cxgbe(4): Add support for Chelsio's Terminator 5 (aka T5) ASIC. This includes support for the NIC and TOE features of the 40G, 10G, and 1G/100M cards based on the T5. The ASIC is mostly backward compatible with the Terminator 4 so cxgbe(4) has been updated instead of writing a brand new driver. T5 cards will show up as cxl (short for cxlgb) ports attached to the t5nex bus driver. Sponsored by: Chelsio

#include "common/common.h"
T4 packet filtering/steering. - Enable 5-tuple and every-packet lookup. - Setup the default filter mode to allow filtering/steering based on IP protocol, ingress port, inner VLAN ID, IP frag, FCoE, and MPS match type; all combined together. You can also filter based on MAC index, Ethernet type, IP TOS/IPv6 Traffic Class, and outer VLAN ID but you'll have to modify the default filter mode and exclude some of the match-fields in it. IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter rules. - Add driver ioctls to get/set the global filter mode. - Add driver ioctls to program and delete hardware filters. A couple of the "switch" actions that rewrite Ethernet and VLAN information and switch the packet out of another port may not work as the L2 code is not yet in place. Everything else, including all "drop" and "pass" rules with RSS or absolute qid, should work. Obtained from: Chelsio Communications

L2 table code. This is enough to get the T4's switch + L2 rewrite filters working. (All other filters - switch without L2 info rewrite, steer, and drop - were already fully-functional). Some contrived examples of "switch" filters with L2 rewriting: # cxgbetool t4nex0 iport 0 dport 80 action switch vlan +9 eport 3 Intercept all packets received on physical port 0 with TCP port 80 as destination, insert a vlan tag with VID 9, and send them out of port 3. # cxgbetool t4nex0 sip 192.168.1.1/32 ivlan 5 action switch \ vlan =9 smac aa:bb:cc:dd:ee:ff eport 0 Intercept all packets (received on any port) with source IP address 192.168.1.1 and VLAN id 5, rewrite the VLAN id to 9, rewrite source mac to aa:bb:cc:dd:ee:ff, and send it out of port 0.

#include "t4_l2t.h"
cxgbe(4): major tx rework. a) Front load as much work as possible in if_transmit, before any driver lock or software queue has to get involved. b) Replace buf_ring with a brand new mp_ring (multiproducer ring). This is specifically for the tx multiqueue model where one of the if_transmit producer threads becomes the consumer and other producers carry on as usual. mp_ring is implemented as standalone code and it should be possible to use it in any driver with tx multiqueue. It also has: - the ability to enqueue/dequeue multiple items. This might become significant if packet batching is ever implemented. - an abdication mechanism to allow a thread to give up writing tx descriptors and have another if_transmit thread take over. A thread that's writing tx descriptors can end up doing so for an unbounded time period if a) there are other if_transmit threads continuously feeding the sofware queue, and b) the chip keeps up with whatever the thread is throwing at it. - accurate statistics about interesting events even when the stats come at the expense of additional branches/conditional code. The NIC txq lock is uncontested on the fast path at this point. I've left it there for synchronization with the control events (interface up/down, modload/unload). c) Add support for "type 1" coalescing work request in the normal NIC tx path. This work request is optimized for frames with a single item in the DMA gather list. These are very common when forwarding packets. Note that netmap tx in cxgbe already uses these "type 1" work requests. d) Do not request automatic cidx updates every 32 descriptors. Instead, request updates via bits in individual work requests (still every 32 descriptors approximately). Also, request an automatic final update when the queue idles after activity. This means NIC tx reclaim is still performed lazily but it will catch up quickly as soon as the queue idles. This seems to be the best middle ground and I'll probably do something similar for netmap tx as well. e) Implement a faster tx path for WRQs (used by TOE tx and control queues, _not_ by the normal NIC tx). Allow work requests to be written directly to the hardware descriptor ring if room is available. I will convert t4_tom and iw_cxgbe modules to this faster style gradually. MFC after: 2 months

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size. T4 gear is totally untested. trantor:~# ./pkt-gen -i ncxl0 -f tx -D 00:07:43:ab:cd:ef 881.952141 main [1621] interface is ncxl0 881.952250 extract_ip_range [275] range is 10.0.0.1:0 to 10.0.0.1:0 881.952253 extract_ip_range [275] range is 10.1.0.1:0 to 10.1.0.1:0 881.962540 main [1804] mapped 334980KB at 0x801dff000 Sending on netmap:ncxl0: 4 queues, 1 threads and 1 cpus. 10.0.0.1 -> 10.1.0.1 (00:00:00:00:00:00 -> 00:07:43:ab:cd:ef) 881.962562 main [1882] Sending 512 packets every 0.000000000 s 881.962563 main [1884] Wait 2 secs for phy reset 884.088516 main [1886] Ready... 884.088535 nm_open [457] overriding ifname ncxl0 ringid 0x0 flags 0x1 884.088607 sender_body [996] start 884.093246 sender_body [1064] drop copy 885.090435 main_thread [1418] 45206353 pps (45289533 pkts in 1001840 usec) 886.091600 main_thread [1418] 45322792 pps (45375593 pkts in 1001165 usec) 887.092435 main_thread [1418] 45313992 pps (45351784 pkts in 1000834 usec) 888.094434 main_thread [1418] 45315765 pps (45406397 pkts in 1002000 usec) 889.095434 main_thread [1418] 45333218 pps (45378551 pkts in 1001000 usec) 890.097434 main_thread [1418] 45315247 pps (45405877 pkts in 1002000 usec) 891.099434 main_thread [1418] 45326515 pps (45417168 pkts in 1002000 usec) 892.101434 main_thread [1418] 45333039 pps (45423705 pkts in 1002000 usec) 893.103434 main_thread [1418] 45324105 pps (45414708 pkts in 1001999 usec) 894.105434 main_thread [1418] 45318042 pps (45408723 pkts in 1002001 usec) 895.106434 main_thread [1418] 45332430 pps (45377762 pkts in 1001000 usec) 896.107434 main_thread [1418] 45338072 pps (45383410 pkts in 1001000 usec) ...

- Updated TOE support in the kernel. - Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs. These are available as t3_tom and t4_tom modules that augment cxgb(4) and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as usual with or without these extra features. - iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the works and will follow soon. Build-tested with make universe. 30s overview ============ What interfaces support TCP offload? Look for TOE4 and/or TOE6 in the capabilities of an interface: # ifconfig -m | grep TOE Enable/disable TCP offload on an interface (just like any other ifnet capability): # ifconfig cxgbe0 toe # ifconfig cxgbe0 -toe Which connections are offloaded? Look for toe4 and/or toe6 in the output of netstat and sockstat: # netstat -np tcp | grep toe # sockstat -46c | grep toe Reviewed by: bz, gnn Sponsored by: Chelsio communications.

T4 packet filtering/steering. - Enable 5-tuple and every-packet lookup. - Setup the default filter mode to allow filtering/steering based on IP protocol, ingress port, inner VLAN ID, IP frag, FCoE, and MPS match type; all combined together. You can also filter based on MAC index, Ethernet type, IP TOS/IPv6 Traffic Class, and outer VLAN ID but you'll have to modify the default filter mode and exclude some of the match-fields in it. IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter rules. - Add driver ioctls to get/set the global filter mode. - Add driver ioctls to program and delete hardware filters. A couple of the "switch" actions that rewrite Ethernet and VLAN information and switch the packet out of another port may not work as the L2 code is not yet in place. Everything else, including all "drop" and "pass" rules with RSS or absolute qid, should work. Obtained from: Chelsio Communications

L2 table code. This is enough to get the T4's switch + L2 rewrite filters working. (All other filters - switch without L2 info rewrite, steer, and drop - were already fully-functional). Some contrived examples of "switch" filters with L2 rewriting: # cxgbetool t4nex0 iport 0 dport 80 action switch vlan +9 eport 3 Intercept all packets received on physical port 0 with TCP port 80 as destination, insert a vlan tag with VID 9, and send them out of port 3. # cxgbetool t4nex0 sip 192.168.1.1/32 ivlan 5 action switch \ vlan =9 smac aa:bb:cc:dd:ee:ff eport 0 Intercept all packets (received on any port) with source IP address 192.168.1.1 and VLAN id 5, rewrite the VLAN id to 9, rewrite source mac to aa:bb:cc:dd:ee:ff, and send it out of port 0.

This is specifically for the tx multiqueue model where one of the if_transmit producer threads becomes the consumer and other producers carry on as usual. mp_ring is implemented as standalone code and it should be possible to use it in any driver with tx multiqueue. It also has: - the ability to enqueue/dequeue multiple items. This might become significant if packet batching is ever implemented. - an abdication mechanism to allow a thread to give up writing tx descriptors and have another if_transmit thread take over. A thread that's writing tx descriptors can end up doing so for an unbounded time period if a) there are other if_transmit threads continuously feeding the sofware queue, and b) the chip keeps up with whatever the thread is throwing at it. - accurate statistics about interesting events even when the stats come at the expense of additional branches/conditional code. The NIC txq lock is uncontested on the fast path at this point. I've left it there for synchronization with the control events (interface up/down, modload/unload). c) Add support for "type 1" coalescing work request in the normal NIC tx path. This work request is optimized for frames with a single item in the DMA gather list. These are very common when forwarding packets. Note that netmap tx in cxgbe already uses these "type 1" work requests. d) Do not request automatic cidx updates every 32 descriptors. Instead, request updates via bits in individual work requests (still every 32 descriptors approximately). Also, request an automatic final update when the queue idles after activity. This means NIC tx reclaim is still performed lazily but it will catch up quickly as soon as the queue idles. This seems to be the best middle ground and I'll probably do something similar for netmap tx as well. e) Implement a faster tx path for WRQs (used by TOE tx and control queues, _not_ by the normal NIC tx). Allow work requests to be written directly to the hardware descriptor ring if room is available. I will convert t4_tom and iw_cxgbe modules to this faster style gradually. MFC after: 2 months

cxgbe(4): Add functions to help synchronize "slow" operations (those not on the fast data path) and use them instead of frobbing the adapter lock and busy flag directly. Other changes made while reworking all slow operations: - Wait for the reply to a filter request (add/delete). This guarantees that the operation is complete by the time the ioctl returns. - Tidy up the tid_info structure. - Do not allow the tx queue size to be set to something that's not a power of 2.

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now.

Add support for packet-sniffing tracers to cxgbe(4). This works with all T4 and T5 based cards and is useful for analyzing TSO, LRO, TOE, and for general purpose monitoring without tapping any cxgbe or cxl ifnet directly. Tracers on the T4/T5 chips provide access to Ethernet frames exactly as they were received from or transmitted on the wire. On transmit, a tracer will capture a frame after TSO segmentation, hw VLAN tag insertion, hw L3 & L4 checksum insertion, etc. It will also capture frames generated by the TCP offload engine (TOE traffic is normally invisible to the kernel). On receive, a tracer will capture a frame before hw VLAN extraction, runt filtering, other badness filtering, before the steering/drop/L2-rewrite filters or the TOE have had a go at it, and of course before sw LRO in the driver. There are 4 tracers on a chip. A tracer can trace only in one direction (tx or rx). For now cxgbetool will set up tracers to capture the first 128B of every transmitted or received frame on a given port. This is a small subset of what the hardware can do. A pseudo ifnet with the same name as the nexus driver (t4nex0 or t5nex0) will be created for tracing. The data delivered to this ifnet is an additional copy made inside the chip. Normal delivery to cxgbe<n> or cxl<n> will be made as usual. /* watch cxl0, which is the first port hanging off t5nex0. */ # cxgbetool t5nex0 tracer 0 tx0 (watch what cxl0 is transmitting) # cxgbetool t5nex0 tracer 1 rx0 (watch what cxl0 is receiving) # cxgbetool t5nex0 tracer list # tcpdump -i t5nex0 <== all that cxl0 sees and puts on the wire If you were doing TSO, a tcpdump on cxl0 may have shown you ~64K "frames" with no L3/L4 checksum but this will show you the frames that were actually transmitted. /* all done */ # cxgbetool t5nex0 tracer 0 disable # cxgbetool t5nex0 tracer 1 disable # cxgbetool t5nex0 tracer list # ifconfig t5nex0 destroy

cxgbe(4): Add support for Chelsio's Terminator 5 (aka T5) ASIC. This includes support for the NIC and TOE features of the 40G, 10G, and 1G/100M cards based on the T5. The ASIC is mostly backward compatible with the Terminator 4 so cxgbe(4) has been updated instead of writing a brand new driver. T5 cards will show up as cxl (short for cxlgb) ports attached to the t5nex bus driver. Sponsored by: Chelsio

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size.

Add support for packet-sniffing tracers to cxgbe(4). This works with all T4 and T5 based cards and is useful for analyzing TSO, LRO, TOE, and for general purpose monitoring without tapping any cxgbe or cxl ifnet directly. Tracers on the T4/T5 chips provide access to Ethernet frames exactly as they were received from or transmitted on the wire. On transmit, a tracer will capture a frame after TSO segmentation, hw VLAN tag insertion, hw L3 & L4 checksum insertion, etc. It will also capture frames generated by the TCP offload engine (TOE traffic is normally invisible to the kernel). On receive, a tracer will capture a frame before hw VLAN extraction, runt filtering, other badness filtering, before the steering/drop/L2-rewrite filters or the TOE have had a go at it, and of course before sw LRO in the driver. There are 4 tracers on a chip. A tracer can trace only in one direction (tx or rx). For now cxgbetool will set up tracers to capture the first 128B of every transmitted or received frame on a given port. This is a small subset of what the hardware can do. A pseudo ifnet with the same name as the nexus driver (t4nex0 or t5nex0) will be created for tracing. The data delivered to this ifnet is an additional copy made inside the chip. Normal delivery to cxgbe<n> or cxl<n> will be made as usual. /* watch cxl0, which is the first port hanging off t5nex0. */ # cxgbetool t5nex0 tracer 0 tx0 (watch what cxl0 is transmitting) # cxgbetool t5nex0 tracer 1 rx0 (watch what cxl0 is receiving) # cxgbetool t5nex0 tracer list # tcpdump -i t5nex0 <== all that cxl0 sees and puts on the wire If you were doing TSO, a tcpdump on cxl0 may have shown you ~64K "frames" with no L3/L4 checksum but this will show you the frames that were actually transmitted. /* all done */ # cxgbetool t5nex0 tracer 0 disable # cxgbetool t5nex0 tracer 1 disable # cxgbetool t5nex0 tracer list # ifconfig t5nex0 destroy

- Updated TOE support in the kernel. - Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs. These are available as t3_tom and t4_tom modules that augment cxgb(4) and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as usual with or without these extra features. - iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the works and will follow soon. Build-tested with make universe. 30s overview ============ What interfaces support TCP offload? Look for TOE4 and/or TOE6 in the capabilities of an interface: # ifconfig -m | grep TOE Enable/disable TCP offload on an interface (just like any other ifnet capability): # ifconfig cxgbe0 toe # ifconfig cxgbe0 -toe Which connections are offloaded?

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done.

Add a new sysctl, dev.cxgbe.N.rsrv_noflow, and a companion tunable, hw.cxgbe.rsrv_noflow. When set, queue 0 of the port is reserved for TX packets without a flowid. The hash value of packets with a flowid is bumped up by 1. The intent is to provide a private queue for link-level packets like LACP that is unlikely to overflow or suffer deep queue latency.

- Updated TOE support in the kernel. - Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs. These are available as t3_tom and t4_tom modules that augment cxgb(4) and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as usual with or without these extra features. - iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the works and will follow soon. Build-tested with make universe. 30s overview ============ What interfaces support TCP offload? Look for TOE4 and/or TOE6 in the capabilities of an interface: # ifconfig -m | grep TOE Enable/disable TCP offload on an interface (just like any other ifnet capability): # ifconfig cxgbe0 toe # ifconfig cxgbe0 -toe Which connections are offloaded? Look for toe4 and/or toe6 in the output of netstat and sockstat: # netstat -np tcp | grep toe # sockstat -46c | grep toe Reviewed by: bz, gnn Sponsored by: Chelsio communications.

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size. T4 gear is totally untested. trantor:~# ./pkt-gen -i ncxl0 -f tx -D 00:07:43:ab:cd:ef 881.952141 main [1621] interface is ncxl0 881.952250 extract_ip_range [275] range is 10.0.0.1:0 to 10.0.0.1:0 881.952253 extract_ip_range [275] range is 10.1.0.1:0 to 10.1.0.1:0 881.962540 main [1804] mapped 334980KB at 0x801dff000 Sending on netmap:ncxl0: 4 queues, 1 threads and 1 cpus. 10.0.0.1 -> 10.1.0.1 (00:00:00:00:00:00 -> 00:07:43:ab:cd:ef) 881.962562 main [1882] Sending 512 packets every 0.000000000 s 881.962563 main [1884] Wait 2 secs for phy reset 884.088516 main [1886] Ready... 884.088535 nm_open [457] overriding ifname ncxl0 ringid 0x0 flags 0x1 884.088607 sender_body [996] start 884.093246 sender_body [1064] drop copy 885.090435 main_thread [1418] 45206353 pps (45289533 pkts in 1001840 usec) 886.091600 main_thread [1418] 45322792 pps (45375593 pkts in 1001165 usec) 887.092435 main_thread [1418] 45313992 pps (45351784 pkts in 1000834 usec) 888.094434 main_thread [1418] 45315765 pps (45406397 pkts in 1002000 usec) 889.095434 main_thread [1418] 45333218 pps (45378551 pkts in 1001000 usec) 890.097434 main_thread [1418] 45315247 pps (45405877 pkts in 1002000 usec) 891.099434 main_thread [1418] 45326515 pps (45417168 pkts in 1002000 usec) 892.101434 main_thread [1418] 45333039 pps (45423705 pkts in 1002000 usec) 893.103434 main_thread [1418] 45324105 pps (45414708 pkts in 1001999 usec) 894.105434 main_thread [1418] 45318042 pps (45408723 pkts in 1002001 usec) 895.106434 main_thread [1418] 45332430 pps (45377762 pkts in 1001000 usec) 896.107434 main_thread [1418] 45338072 pps (45383410 pkts in 1001000 usec) ...

cxgbe(4): Add support for Chelsio's Terminator 5 (aka T5) ASIC. This includes support for the NIC and TOE features of the 40G, 10G, and 1G/100M cards based on the T5. The ASIC is mostly backward compatible with the Terminator 4 so cxgbe(4) has been updated instead of writing a brand new driver.

L2 table code. This is enough to get the T4's switch + L2 rewrite filters working. (All other filters - switch without L2 info rewrite, steer, and drop - were already fully-functional). Some contrived examples of "switch" filters with L2 rewriting: # cxgbetool t4nex0 iport 0 dport 80 action switch vlan +9 eport 3 Intercept all packets received on physical port 0 with TCP port 80 as destination, insert a vlan tag with VID 9, and send them out of port 3. # cxgbetool t4nex0 sip 192.168.1.1/32 ivlan 5 action switch \ vlan =9 smac aa:bb:cc:dd:ee:ff eport 0 Intercept all packets (received on any port) with source IP address 192.168.1.1 and VLAN id 5, rewrite the VLAN id to 9, rewrite source mac to aa:bb:cc:dd:ee:ff, and send it out of port 0.

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done.

Add support for packet-sniffing tracers to cxgbe(4). This works with all T4 and T5 based cards and is useful for analyzing TSO, LRO, TOE, and for general purpose monitoring without tapping any cxgbe or cxl ifnet directly. Tracers on the T4/T5 chips provide access to Ethernet frames exactly as they were received from or transmitted on the wire. On transmit, a tracer will capture a frame after TSO segmentation, hw VLAN tag insertion, hw L3 & L4 checksum insertion, etc. It will also capture frames generated by the TCP offload engine (TOE traffic is normally invisible to the kernel). On receive, a tracer will capture a frame before hw VLAN extraction, runt filtering, other badness filtering, before the steering/drop/L2-rewrite filters or the TOE have had a go at it, and of course before sw LRO in the driver. There are 4 tracers on a chip. A tracer can trace only in one direction (tx or rx). For now cxgbetool will set up tracers to capture the first 128B of every transmitted or received frame on a given port. This is a small subset of what the hardware can do. A pseudo ifnet with the same name as the nexus driver (t4nex0 or t5nex0) will be created for tracing. The data delivered to this ifnet is an additional copy made inside the chip. Normal delivery to cxgbe<n> or cxl<n> will be made as usual. /* watch cxl0, which is the first port hanging off t5nex0. */ # cxgbetool t5nex0 tracer 0 tx0 (watch what cxl0 is transmitting) # cxgbetool t5nex0 tracer 1 rx0 (watch what cxl0 is receiving) # cxgbetool t5nex0 tracer list # tcpdump -i t5nex0 <== all that cxl0 sees and puts on the wire If you were doing TSO, a tcpdump on cxl0 may have shown you ~64K "frames" with no L3/L4 checksum but this will show you the frames that were actually transmitted. /* all done */ # cxgbetool t5nex0 tracer 0 disable # cxgbetool t5nex0 tracer 1 disable # cxgbetool t5nex0 tracer list # ifconfig t5nex0 destroy

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size. T4 gear is totally untested. trantor:~# ./pkt-gen -i ncxl0 -f tx -D 00:07:43:ab:cd:ef 881.952141 main [1621] interface is ncxl0 881.952250 extract_ip_range [275] range is 10.0.0.1:0 to 10.0.0.1:0 881.952253 extract_ip_range [275] range is 10.1.0.1:0 to 10.1.0.1:0 881.962540 main [1804] mapped 334980KB at 0x801dff000 Sending on netmap:ncxl0: 4 queues, 1 threads and 1 cpus. 10.0.0.1 -> 10.1.0.1 (00:00:00:00:00:00 -> 00:07:43:ab:cd:ef) 881.962562 main [1882] Sending 512 packets every 0.000000000 s 881.962563 main [1884] Wait 2 secs for phy reset 884.088516 main [1886] Ready... 884.088535 nm_open [457] overriding ifname ncxl0 ringid 0x0 flags 0x1 884.088607 sender_body [996] start 884.093246 sender_body [1064] drop copy 885.090435 main_thread [1418] 45206353 pps (45289533 pkts in 1001840 usec) 886.091600 main_thread [1418] 45322792 pps (45375593 pkts in 1001165 usec) 887.092435 main_thread [1418] 45313992 pps (45351784 pkts in 1000834 usec) 888.094434 main_thread [1418] 45315765 pps (45406397 pkts in 1002000 usec) 889.095434 main_thread [1418] 45333218 pps (45378551 pkts in 1001000 usec) 890.097434 main_thread [1418] 45315247 pps (45405877 pkts in 1002000 usec) 891.099434 main_thread [1418] 45326515 pps (45417168 pkts in 1002000 usec) 892.101434 main_thread [1418] 45333039 pps (45423705 pkts in 1002000 usec) 893.103434 main_thread [1418] 45324105 pps (45414708 pkts in 1001999 usec) 894.105434 main_thread [1418] 45318042 pps (45408723 pkts in 1002001 usec) 895.106434 main_thread [1418] 45332430 pps (45377762 pkts in 1001000 usec) 896.107434 main_thread [1418] 45338072 pps (45383410 pkts in 1001000 usec) ...

Other changes made while reworking all slow operations: - Wait for the reply to a filter request (add/delete). This guarantees that the operation is complete by the time the ioctl returns. - Tidy up the tid_info structure. - Do not allow the tx queue size to be set to something that's not a power of 2.

Add support for packet-sniffing tracers to cxgbe(4). This works with all T4 and T5 based cards and is useful for analyzing TSO, LRO, TOE, and for general purpose monitoring without tapping any cxgbe or cxl ifnet directly. Tracers on the T4/T5 chips provide access to Ethernet frames exactly as they were received from or transmitted on the wire. On transmit, a tracer will capture a frame after TSO segmentation, hw VLAN tag insertion, hw L3 & L4 checksum insertion, etc. It will also capture frames generated by the TCP offload engine (TOE traffic is normally invisible to the kernel). On receive, a tracer will capture a frame before hw VLAN extraction, runt filtering, other badness filtering, before the steering/drop/L2-rewrite filters or the TOE have had a go at it, and of course before sw LRO in the driver. There are 4 tracers on a chip. A tracer can trace only in one direction (tx or rx). For now cxgbetool will set up tracers to capture the first 128B of every transmitted or received frame on a given port. This is a small subset of what the hardware can do. A pseudo ifnet with the same name as the nexus driver (t4nex0 or t5nex0) will be created for tracing. The data delivered to this ifnet is an additional copy made inside the chip. Normal delivery to cxgbe<n> or cxl<n> will be made as usual. /* watch cxl0, which is the first port hanging off t5nex0. */ # cxgbetool t5nex0 tracer 0 tx0 (watch what cxl0 is transmitting) # cxgbetool t5nex0 tracer 1 rx0 (watch what cxl0 is receiving) # cxgbetool t5nex0 tracer list # tcpdump -i t5nex0 <== all that cxl0 sees and puts on the wire If you were doing TSO, a tcpdump on cxl0 may have shown you ~64K "frames" with no L3/L4 checksum but this will show you the frames that were actually transmitted. /* all done */ # cxgbetool t5nex0 tracer 0 disable # cxgbetool t5nex0 tracer 1 disable # cxgbetool t5nex0 tracer list # ifconfig t5nex0 destroy

- Updated TOE support in the kernel. - Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs. These are available as t3_tom and t4_tom modules that augment cxgb(4) and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as usual with or without these extra features. - iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the works and will follow soon. Build-tested with make universe. 30s overview ============ What interfaces support TCP offload? Look for TOE4 and/or TOE6 in the capabilities of an interface: # ifconfig -m | grep TOE Enable/disable TCP offload on an interface (just like any other ifnet capability): # ifconfig cxgbe0 toe # ifconfig cxgbe0 -toe Which connections are offloaded?

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now.

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done.

cxgbe(4): Add functions to help synchronize "slow" operations (those not on the fast data path) and use them instead of frobbing the adapter lock and busy flag directly. Other changes made while reworking all slow operations: - Wait for the reply to a filter request (add/delete). This guarantees that the operation is complete by the time the ioctl returns. - Tidy up the tid_info structure. - Do not allow the tx queue size to be set to something that's not a power of 2.

cxgbe(4): major tx rework. a) Front load as much work as possible in if_transmit, before any driver lock or software queue has to get involved. b) Replace buf_ring with a brand new mp_ring (multiproducer ring). This is specifically for the tx multiqueue model where one of the if_transmit producer threads becomes the consumer and other producers carry on as usual. mp_ring is implemented as standalone code and it should be possible to use it in any driver with tx multiqueue. It also has: - the ability to enqueue/dequeue multiple items. This might become significant if packet batching is ever implemented. - an abdication mechanism to allow a thread to give up writing tx descriptors and have another if_transmit thread take over. A thread that's writing tx descriptors can end up doing so for an unbounded time period if a) there are other if_transmit threads continuously feeding the sofware queue, and b) the chip keeps up with whatever the thread is throwing at it. - accurate statistics about interesting events even when the stats come at the expense of additional branches/conditional code. The NIC txq lock is uncontested on the fast path at this point. I've left it there for synchronization with the control events (interface up/down, modload/unload). c) Add support for "type 1" coalescing work request in the normal NIC tx path. This work request is optimized for frames with a single item in the DMA gather list. These are very common when forwarding packets. Note that netmap tx in cxgbe already uses these "type 1" work requests. d) Do not request automatic cidx updates every 32 descriptors. Instead, request updates via bits in individual work requests (still every 32 descriptors approximately). Also, request an automatic final update when the queue idles after activity. This means NIC tx reclaim is still performed lazily but it will catch up quickly as soon as the queue idles. This seems to be the best middle ground and I'll probably do something similar for netmap tx as well. e) Implement a faster tx path for WRQs (used by TOE tx and control queues, _not_ by the normal NIC tx). Allow work requests to be written directly to the hardware descriptor ring if room is available. I will convert t4_tom and iw_cxgbe modules to this faster style gradually. MFC after: 2 months

A thread that's writing tx descriptors can end up doing so for an unbounded time period if a) there are other if_transmit threads continuously feeding the sofware queue, and b) the chip keeps up with whatever the thread is throwing at it. - accurate statistics about interesting events even when the stats come at the expense of additional branches/conditional code. The NIC txq lock is uncontested on the fast path at this point. I've left it there for synchronization with the control events (interface up/down, modload/unload). c) Add support for "type 1" coalescing work request in the normal NIC tx path. This work request is optimized for frames with a single item in the DMA gather list. These are very common when forwarding packets. Note that netmap tx in cxgbe already uses these "type 1" work requests. d) Do not request automatic cidx updates every 32 descriptors. Instead, request updates via bits in individual work requests (still every 32 descriptors approximately). Also, request an automatic final update when the queue idles after activity. This means NIC tx reclaim is still performed lazily but it will catch up quickly as soon as the queue idles. This seems to be the best middle ground and I'll probably do something similar for netmap tx as well. e) Implement a faster tx path for WRQs (used by TOE tx and control queues, _not_ by the normal NIC tx). Allow work requests to be written directly to the hardware descriptor ring if room is available. I will convert t4_tom and iw_cxgbe modules to this faster style gradually. MFC after: 2 months

Fix a couple of bad races that can occur when a cxgbe interface is taken down. The ingress queue lock was unused and has been removed as part of these changes. - An in-flight egress update from the SGE must be handled before the queue that requested it is destroyed. Wait for the update to arrive. - Interrupt handlers must stop processing rx events for a queue before the queue is destroyed. Events that have not yet been processed should be ignored once the queue disappears. MFC after: 1 week

cxgbe(4): major tx rework. a) Front load as much work as possible in if_transmit, before any driver lock or software queue has to get involved. b) Replace buf_ring with a brand new mp_ring (multiproducer ring). This is specifically for the tx multiqueue model where one of the if_transmit producer threads becomes the consumer and other producers carry on as usual. mp_ring is implemented as standalone code and it should be possible to use it in any driver with tx multiqueue. It also has: - the ability to enqueue/dequeue multiple items. This might become significant if packet batching is ever implemented. - an abdication mechanism to allow a thread to give up writing tx descriptors and have another if_transmit thread take over.

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size.

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done.

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done.

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software.

Many updates to cxgbe(4) - Device configuration via plain text config file. Also able to operate when not attached to the chip as the master driver. - Generic "work request" queue that serves as the base for both ctrl and ofld tx queues. - Generic interrupt handler routine that can process any event on any kind of ingress queue (via a dispatch table). - A couple of new driver ioctls. cxgbetool can now install a firmware to the card ("loadfw" command) and can read the card's memory ("memdump" and "tcb" commands). - Lots of assorted information within dev.t4nex.X.misc.* This is primarily for debugging and won't show up in sysctl -a. - Code to manage the L2 tables on the chip. - Updates to cxgbe(4) man page to go with the tunables that have changed. - Updates to the shared code in common/ - Updates to the driver-firmware interface (now at fw 1.4.16.0) MFC after: 1 month

cxgbe(4): Add support for Chelsio's Terminator 5 (aka T5) ASIC. This includes support for the NIC and TOE features of the 40G, 10G, and 1G/100M cards based on the T5. The ASIC is mostly backward compatible with the Terminator 4 so cxgbe(4) has been updated instead of writing a brand new driver. T5 cards will show up as cxl (short for cxlgb) ports attached to the t5nex bus driver. Sponsored by: Chelsio

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size. T4 gear is totally untested. trantor:~# ./pkt-gen -i ncxl0 -f tx -D 00:07:43:ab:cd:ef 881.952141 main [1621] interface is ncxl0 881.952250 extract_ip_range [275] range is 10.0.0.1:0 to 10.0.0.1:0 881.952253 extract_ip_range [275] range is 10.1.0.1:0 to 10.1.0.1:0 881.962540 main [1804] mapped 334980KB at 0x801dff000 Sending on netmap:ncxl0: 4 queues, 1 threads and 1 cpus. 10.0.0.1 -> 10.1.0.1 (00:00:00:00:00:00 -> 00:07:43:ab:cd:ef) 881.962562 main [1882] Sending 512 packets every 0.000000000 s 881.962563 main [1884] Wait 2 secs for phy reset 884.088516 main [1886] Ready... 884.088535 nm_open [457] overriding ifname ncxl0 ringid 0x0 flags 0x1 884.088607 sender_body [996] start 884.093246 sender_body [1064] drop copy 885.090435 main_thread [1418] 45206353 pps (45289533 pkts in 1001840 usec) 886.091600 main_thread [1418] 45322792 pps (45375593 pkts in 1001165 usec) 887.092435 main_thread [1418] 45313992 pps (45351784 pkts in 1000834 usec) 888.094434 main_thread [1418] 45315765 pps (45406397 pkts in 1002000 usec) 889.095434 main_thread [1418] 45333218 pps (45378551 pkts in 1001000 usec) 890.097434 main_thread [1418] 45315247 pps (45405877 pkts in 1002000 usec) 891.099434 main_thread [1418] 45326515 pps (45417168 pkts in 1002000 usec) 892.101434 main_thread [1418] 45333039 pps (45423705 pkts in 1002000 usec) 893.103434 main_thread [1418] 45324105 pps (45414708 pkts in 1001999 usec) 894.105434 main_thread [1418] 45318042 pps (45408723 pkts in 1002001 usec) 895.106434 main_thread [1418] 45332430 pps (45377762 pkts in 1001000 usec) 896.107434 main_thread [1418] 45338072 pps (45383410 pkts in 1001000 usec) ...

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done.

cxgbe(4): Add functions to help synchronize "slow" operations (those not on the fast data path) and use them instead of frobbing the adapter lock and busy flag directly. Other changes made while reworking all slow operations: - Wait for the reply to a filter request (add/delete). This guarantees that the operation is complete by the time the ioctl returns. - Tidy up the tid_info structure. - Do not allow the tx queue size to be set to something that's not a power of 2.

You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size.

cxgbe(4): major tx rework. a) Front load as much work as possible in if_transmit, before any driver lock or software queue has to get involved. b) Replace buf_ring with a brand new mp_ring (multiproducer ring). This is specifically for the tx multiqueue model where one of the if_transmit producer threads becomes the consumer and other producers carry on as usual. mp_ring is implemented as standalone code and it should be possible to use it in any driver with tx multiqueue. It also has: - the ability to enqueue/dequeue multiple items. This might become significant if packet batching is ever implemented. - an abdication mechanism to allow a thread to give up writing tx descriptors and have another if_transmit thread take over. A thread that's writing tx descriptors can end up doing so for an unbounded time period if a) there are other if_transmit threads continuously feeding the sofware queue, and b) the chip keeps up with whatever the thread is throwing at it. - accurate statistics about interesting events even when the stats come at the expense of additional branches/conditional code. The NIC txq lock is uncontested on the fast path at this point. I've left it there for synchronization with the control events (interface up/down, modload/unload). c) Add support for "type 1" coalescing work request in the normal NIC tx path. This work request is optimized for frames with a single item in the DMA gather list. These are very common when forwarding packets. Note that netmap tx in cxgbe already uses these "type 1" work requests. d) Do not request automatic cidx updates every 32 descriptors. Instead, request updates via bits in individual work requests (still every 32 descriptors approximately). Also, request an automatic final update when the queue idles after activity. This means NIC tx reclaim is still performed lazily but it will catch up quickly as soon as the queue idles. This seems to be the best middle ground and I'll probably do something similar for netmap tx as well. e) Implement a faster tx path for WRQs (used by TOE tx and control queues, _not_ by the normal NIC tx). Allow work requests to be written directly to the hardware descriptor ring if room is available. I will convert t4_tom and iw_cxgbe modules to this faster style gradually. MFC after: 2 months

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size. T4 gear is totally untested. trantor:~# ./pkt-gen -i ncxl0 -f tx -D 00:07:43:ab:cd:ef 881.952141 main [1621] interface is ncxl0 881.952250 extract_ip_range [275] range is 10.0.0.1:0 to 10.0.0.1:0 881.952253 extract_ip_range [275] range is 10.1.0.1:0 to 10.1.0.1:0 881.962540 main [1804] mapped 334980KB at 0x801dff000 Sending on netmap:ncxl0: 4 queues, 1 threads and 1 cpus. 10.0.0.1 -> 10.1.0.1 (00:00:00:00:00:00 -> 00:07:43:ab:cd:ef) 881.962562 main [1882] Sending 512 packets every 0.000000000 s 881.962563 main [1884] Wait 2 secs for phy reset 884.088516 main [1886] Ready... 884.088535 nm_open [457] overriding ifname ncxl0 ringid 0x0 flags 0x1 884.088607 sender_body [996] start 884.093246 sender_body [1064] drop copy 885.090435 main_thread [1418] 45206353 pps (45289533 pkts in 1001840 usec) 886.091600 main_thread [1418] 45322792 pps (45375593 pkts in 1001165 usec) 887.092435 main_thread [1418] 45313992 pps (45351784 pkts in 1000834 usec) 888.094434 main_thread [1418] 45315765 pps (45406397 pkts in 1002000 usec) 889.095434 main_thread [1418] 45333218 pps (45378551 pkts in 1001000 usec) 890.097434 main_thread [1418] 45315247 pps (45405877 pkts in 1002000 usec) 891.099434 main_thread [1418] 45326515 pps (45417168 pkts in 1002000 usec) 892.101434 main_thread [1418] 45333039 pps (45423705 pkts in 1002000 usec) 893.103434 main_thread [1418] 45324105 pps (45414708 pkts in 1001999 usec) 894.105434 main_thread [1418] 45318042 pps (45408723 pkts in 1002001 usec) 895.106434 main_thread [1418] 45332430 pps (45377762 pkts in 1001000 usec) 896.107434 main_thread [1418] 45338072 pps (45383410 pkts in 1001000 usec) ...

Add support for packet-sniffing tracers to cxgbe(4). This works with all T4 and T5 based cards and is useful for analyzing TSO, LRO, TOE, and for general purpose monitoring without tapping any cxgbe or cxl ifnet directly. Tracers on the T4/T5 chips provide access to Ethernet frames exactly as they were received from or transmitted on the wire. On transmit, a tracer will capture a frame after TSO segmentation, hw VLAN tag insertion, hw L3 & L4 checksum insertion, etc. It will also capture frames generated by the TCP offload engine (TOE traffic is normally invisible to the kernel). On receive, a tracer will capture a frame before hw VLAN extraction, runt filtering, other badness filtering, before the steering/drop/L2-rewrite filters or the TOE have had a go at it, and of course before sw LRO in the driver. There are 4 tracers on a chip. A tracer can trace only in one direction (tx or rx). For now cxgbetool will set up tracers to capture the first 128B of every transmitted or received frame on a given port. This is a small subset of what the hardware can do. A pseudo ifnet with the same name as the nexus driver (t4nex0 or t5nex0) will be created for tracing. The data delivered to this ifnet is an additional copy made inside the chip. Normal delivery to cxgbe<n> or cxl<n> will be made as usual. /* watch cxl0, which is the first port hanging off t5nex0. */ # cxgbetool t5nex0 tracer 0 tx0 (watch what cxl0 is transmitting) # cxgbetool t5nex0 tracer 1 rx0 (watch what cxl0 is receiving) # cxgbetool t5nex0 tracer list # tcpdump -i t5nex0 <== all that cxl0 sees and puts on the wire If you were doing TSO, a tcpdump on cxl0 may have shown you ~64K "frames" with no L3/L4 checksum but this will show you the frames that were actually transmitted. /* all done */ # cxgbetool t5nex0 tracer 0 disable # cxgbetool t5nex0 tracer 1 disable # cxgbetool t5nex0 tracer list # ifconfig t5nex0 destroy

cxgbe(4): major tx rework. a) Front load as much work as possible in if_transmit, before any driver lock or software queue has to get involved. b) Replace buf_ring with a brand new mp_ring (multiproducer ring). This is specifically for the tx multiqueue model where one of the if_transmit producer threads becomes the consumer and other producers carry on as usual. mp_ring is implemented as standalone code and it should be possible to use it in any driver with tx multiqueue. It also has: - the ability to enqueue/dequeue multiple items. This might become significant if packet batching is ever implemented. - an abdication mechanism to allow a thread to give up writing tx descriptors and have another if_transmit thread take over. A thread that's writing tx descriptors can end up doing so for an unbounded time period if a) there are other if_transmit threads continuously feeding the sofware queue, and b) the chip keeps up with whatever the thread is throwing at it. - accurate statistics about interesting events even when the stats come at the expense of additional branches/conditional code. The NIC txq lock is uncontested on the fast path at this point. I've left it there for synchronization with the control events (interface up/down, modload/unload). c) Add support for "type 1" coalescing work request in the normal NIC tx path. This work request is optimized for frames with a single item in the DMA gather list. These are very common when forwarding packets. Note that netmap tx in cxgbe already uses these "type 1" work requests. d) Do not request automatic cidx updates every 32 descriptors. Instead, request updates via bits in individual work requests (still every 32 descriptors approximately). Also, request an automatic final update when the queue idles after activity. This means NIC tx reclaim is still performed lazily but it will catch up quickly as soon as the queue idles. This seems to be the best middle ground and I'll probably do something similar for netmap tx as well. e) Implement a faster tx path for WRQs (used by TOE tx and control queues, _not_ by the normal NIC tx). Allow work requests to be written directly to the hardware descriptor ring if room is available. I will convert t4_tom and iw_cxgbe modules to this faster style gradually. MFC after: 2 months

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size.

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size.

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size.

- Updated TOE support in the kernel. - Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs. These are available as t3_tom and t4_tom modules that augment cxgb(4) and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as usual with or without these extra features. - iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the works and will follow soon. Build-tested with make universe. 30s overview ============ What interfaces support TCP offload? Look for TOE4 and/or TOE6 in the capabilities of an interface: # ifconfig -m | grep TOE Enable/disable TCP offload on an interface (just like any other ifnet capability): # ifconfig cxgbe0 toe # ifconfig cxgbe0 -toe Which connections are offloaded? Look for toe4 and/or toe6 in the output of netstat and sockstat: # netstat -np tcp | grep toe # sockstat -46c | grep toe Reviewed by: bz, gnn Sponsored by: Chelsio communications.

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done.

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size.

cxgbe(4): major tx rework. a) Front load as much work as possible in if_transmit, before any driver lock or software queue has to get involved. b) Replace buf_ring with a brand new mp_ring (multiproducer ring). This is specifically for the tx multiqueue model where one of the if_transmit producer threads becomes the consumer and other producers carry on as usual. mp_ring is implemented as standalone code and it should be possible to use it in any driver with tx multiqueue. It also has: - the ability to enqueue/dequeue multiple items. This might become significant if packet batching is ever implemented. - an abdication mechanism to allow a thread to give up writing tx descriptors and have another if_transmit thread take over. A thread that's writing tx descriptors can end up doing so for an unbounded time period if a) there are other if_transmit threads continuously feeding the sofware queue, and b) the chip keeps up with whatever the thread is throwing at it. - accurate statistics about interesting events even when the stats come at the expense of additional branches/conditional code. The NIC txq lock is uncontested on the fast path at this point. I've left it there for synchronization with the control events (interface up/down, modload/unload). c) Add support for "type 1" coalescing work request in the normal NIC tx path. This work request is optimized for frames with a single item in the DMA gather list. These are very common when forwarding packets. Note that netmap tx in cxgbe already uses these "type 1" work requests. d) Do not request automatic cidx updates every 32 descriptors. Instead, request updates via bits in individual work requests (still every 32 descriptors approximately). Also, request an automatic final update when the queue idles after activity. This means NIC tx reclaim is still performed lazily but it will catch up quickly as soon as the queue idles. This seems to be the best middle ground and I'll probably do something similar for netmap tx as well. e) Implement a faster tx path for WRQs (used by TOE tx and control queues, _not_ by the normal NIC tx). Allow work requests to be written directly to the hardware descriptor ring if room is available. I will convert t4_tom and iw_cxgbe modules to this faster style gradually. MFC after: 2 months

Many updates to cxgbe(4) - Device configuration via plain text config file. Also able to operate when not attached to the chip as the master driver. - Generic "work request" queue that serves as the base for both ctrl and ofld tx queues. - Generic interrupt handler routine that can process any event on any kind of ingress queue (via a dispatch table). - A couple of new driver ioctls. cxgbetool can now install a firmware to the card ("loadfw" command) and can read the card's memory ("memdump" and "tcb" commands). - Lots of assorted information within dev.t4nex.X.misc.* This is primarily for debugging and won't show up in sysctl -a. - Code to manage the L2 tables on the chip. - Updates to cxgbe(4) man page to go with the tunables that have changed. - Updates to the shared code in common/ - Updates to the driver-firmware interface (now at fw 1.4.16.0) MFC after: 1 month

cxgbe(4): major tx rework. a) Front load as much work as possible in if_transmit, before any driver lock or software queue has to get involved. b) Replace buf_ring with a brand new mp_ring (multiproducer ring). This is specifically for the tx multiqueue model where one of the if_transmit producer threads becomes the consumer and other producers carry on as usual. mp_ring is implemented as standalone code and it should be possible to use it in any driver with tx multiqueue. It also has: - the ability to enqueue/dequeue multiple items. This might become significant if packet batching is ever implemented. - an abdication mechanism to allow a thread to give up writing tx descriptors and have another if_transmit thread take over. A thread that's writing tx descriptors can end up doing so for an unbounded time period if a) there are other if_transmit threads continuously feeding the sofware queue, and b) the chip keeps up with whatever the thread is throwing at it. - accurate statistics about interesting events even when the stats come at the expense of additional branches/conditional code. The NIC txq lock is uncontested on the fast path at this point. I've left it there for synchronization with the control events (interface up/down, modload/unload). c) Add support for "type 1" coalescing work request in the normal NIC tx path. This work request is optimized for frames with a single item in the DMA gather list. These are very common when forwarding packets. Note that netmap tx in cxgbe already uses these "type 1" work requests. d) Do not request automatic cidx updates every 32 descriptors. Instead, request updates via bits in individual work requests (still every 32 descriptors approximately). Also, request an automatic final update when the queue idles after activity. This means NIC tx reclaim is still performed lazily but it will catch up quickly as soon as the queue idles. This seems to be the best middle ground and I'll probably do something similar for netmap tx as well. e) Implement a faster tx path for WRQs (used by TOE tx and control queues, _not_ by the normal NIC tx). Allow work requests to be written directly to the hardware descriptor ring if room is available. I will convert t4_tom and iw_cxgbe modules to this faster style gradually. MFC after: 2 months

cxgbe(4): Add support for Chelsio's Terminator 5 (aka T5) ASIC. This includes support for the NIC and TOE features of the 40G, 10G, and 1G/100M cards based on the T5. The ASIC is mostly backward compatible with the Terminator 4 so cxgbe(4) has been updated instead of writing a brand new driver. T5 cards will show up as cxl (short for cxlgb) ports attached to the t5nex bus driver. Sponsored by: Chelsio

The ASIC is mostly backward compatible with the Terminator 4 so cxgbe(4) has been updated instead of writing a brand new driver. T5 cards will show up as cxl (short for cxlgb) ports attached to the t5nex bus driver. Sponsored by: Chelsio

- Updated TOE support in the kernel. - Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs. These are available as t3_tom and t4_tom modules that augment cxgb(4) and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as usual with or without these extra features. - iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the works and will follow soon. Build-tested with make universe. 30s overview ============ What interfaces support TCP offload? Look for TOE4 and/or TOE6 in the capabilities of an interface: # ifconfig -m | grep TOE Enable/disable TCP offload on an interface (just like any other ifnet capability): # ifconfig cxgbe0 toe # ifconfig cxgbe0 -toe Which connections are offloaded? Look for toe4 and/or toe6 in the output of netstat and sockstat: # netstat -np tcp | grep toe # sockstat -46c | grep toe Reviewed by: bz, gnn Sponsored by: Chelsio communications.

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size.

cxgbe(4): major tx rework. a) Front load as much work as possible in if_transmit, before any driver lock or software queue has to get involved. b) Replace buf_ring with a brand new mp_ring (multiproducer ring). This is specifically for the tx multiqueue model where one of the if_transmit producer threads becomes the consumer and other producers carry on as usual. mp_ring is implemented as standalone code and it should be possible to use it in any driver with tx multiqueue. It also has: - the ability to enqueue/dequeue multiple items. This might become significant if packet batching is ever implemented. - an abdication mechanism to allow a thread to give up writing tx descriptors and have another if_transmit thread take over. A thread that's writing tx descriptors can end up doing so for an unbounded time period if a) there are other if_transmit threads continuously feeding the sofware queue, and b) the chip keeps up with whatever the thread is throwing at it. - accurate statistics about interesting events even when the stats come at the expense of additional branches/conditional code. The NIC txq lock is uncontested on the fast path at this point. I've left it there for synchronization with the control events (interface up/down, modload/unload). c) Add support for "type 1" coalescing work request in the normal NIC tx path. This work request is optimized for frames with a single item in the DMA gather list. These are very common when forwarding packets. Note that netmap tx in cxgbe already uses these "type 1" work requests. d) Do not request automatic cidx updates every 32 descriptors. Instead, request updates via bits in individual work requests (still every 32 descriptors approximately). Also, request an automatic final update when the queue idles after activity. This means NIC tx reclaim is still performed lazily but it will catch up quickly as soon as the queue idles. This seems to be the best middle ground and I'll probably do something similar for netmap tx as well. e) Implement a faster tx path for WRQs (used by TOE tx and control queues, _not_ by the normal NIC tx). Allow work requests to be written directly to the hardware descriptor ring if room is available. I will convert t4_tom and iw_cxgbe modules to this faster style gradually. MFC after: 2 months

Add a new sysctl, dev.cxgbe.N.rsrv_noflow, and a companion tunable, hw.cxgbe.rsrv_noflow. When set, queue 0 of the port is reserved for TX packets without a flowid. The hash value of packets with a flowid is bumped up by 1. The intent is to provide a private queue for link-level packets like LACP that is unlikely to overflow or suffer deep queue latency.

#ifdef SBUF_DRAIN
Many updates to cxgbe(4) - Device configuration via plain text config file. Also able to operate when not attached to the chip as the master driver. - Generic "work request" queue that serves as the base for both ctrl and ofld tx queues. - Generic interrupt handler routine that can process any event on any kind of ingress queue (via a dispatch table). - A couple of new driver ioctls. cxgbetool can now install a firmware to the card ("loadfw" command) and can read the card's memory ("memdump" and "tcb" commands). - Lots of assorted information within dev.t4nex.X.misc.* This is primarily for debugging and won't show up in sysctl -a. - Code to manage the L2 tables on the chip. - Updates to cxgbe(4) man page to go with the tunables that have changed. - Updates to the shared code in common/ - Updates to the driver-firmware interface (now at fw 1.4.16.0) MFC after: 1 month

cxgbe(4): Add support for Chelsio's Terminator 5 (aka T5) ASIC. This includes support for the NIC and TOE features of the 40G, 10G, and 1G/100M cards based on the T5. The ASIC is mostly backward compatible with the Terminator 4 so cxgbe(4) has been updated instead of writing a brand new driver. T5 cards will show up as cxl (short for cxlgb) ports attached to the t5nex bus driver. Sponsored by: Chelsio

T4 packet filtering/steering. - Enable 5-tuple and every-packet lookup. - Setup the default filter mode to allow filtering/steering based on IP protocol, ingress port, inner VLAN ID, IP frag, FCoE, and MPS match type; all combined together. You can also filter based on MAC index, Ethernet type, IP TOS/IPv6 Traffic Class, and outer VLAN ID but you'll have to modify the default filter mode and exclude some of the match-fields in it. IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter rules. - Add driver ioctls to get/set the global filter mode. - Add driver ioctls to program and delete hardware filters. A couple of the "switch" actions that rewrite Ethernet and VLAN information and switch the packet out of another port may not work as the L2 code is not yet in place.

IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter rules. - Add driver ioctls to get/set the global filter mode. - Add driver ioctls to program and delete hardware filters. A couple of the "switch" actions that rewrite Ethernet and VLAN information and switch the packet out of another port may not work as the L2 code is not yet in place. Everything else, including all "drop" and "pass" rules with RSS or absolute qid, should work. Obtained from: Chelsio Communications

cxgbe(4): major tx rework. a) Front load as much work as possible in if_transmit, before any driver lock or software queue has to get involved. b) Replace buf_ring with a brand new mp_ring (multiproducer ring). This is specifically for the tx multiqueue model where one of the if_transmit producer threads becomes the consumer and other producers carry on as usual. mp_ring is implemented as standalone code and it should be possible to use it in any driver with tx multiqueue. It also has: - the ability to enqueue/dequeue multiple items. This might become significant if packet batching is ever implemented. - an abdication mechanism to allow a thread to give up writing tx descriptors and have another if_transmit thread take over. A thread that's writing tx descriptors can end up doing so for an unbounded time period if a) there are other if_transmit threads continuously feeding the sofware queue, and b) the chip keeps up with whatever the thread is throwing at it. - accurate statistics about interesting events even when the stats come at the expense of additional branches/conditional code. The NIC txq lock is uncontested on the fast path at this point. I've left it there for synchronization with the control events (interface up/down, modload/unload). c) Add support for "type 1" coalescing work request in the normal NIC tx path. This work request is optimized for frames with a single item in the DMA gather list. These are very common when forwarding packets. Note that netmap tx in cxgbe already uses these "type 1" work requests. d) Do not request automatic cidx updates every 32 descriptors. Instead, request updates via bits in individual work requests (still every 32 descriptors approximately). Also, request an automatic final update when the queue idles after activity. This means NIC tx reclaim is still performed lazily but it will catch up quickly as soon as the queue idles. This seems to be the best middle ground and I'll probably do something similar for netmap tx as well. e) Implement a faster tx path for WRQs (used by TOE tx and control queues, _not_ by the normal NIC tx). Allow work requests to be written directly to the hardware descriptor ring if room is available. I will convert t4_tom and iw_cxgbe modules to this faster style gradually. MFC after: 2 months

T4 packet filtering/steering. - Enable 5-tuple and every-packet lookup. - Setup the default filter mode to allow filtering/steering based on IP protocol, ingress port, inner VLAN ID, IP frag, FCoE, and MPS match type; all combined together. You can also filter based on MAC index, Ethernet type, IP TOS/IPv6 Traffic Class, and outer VLAN ID but you'll have to modify the default filter mode and exclude some of the match-fields in it. IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter rules. - Add driver ioctls to get/set the global filter mode. - Add driver ioctls to program and delete hardware filters. A couple of the "switch" actions that rewrite Ethernet and VLAN information and switch the packet out of another port may not work as the L2 code is not yet in place. Everything else, including all "drop" and "pass" rules with RSS or absolute qid, should work. Obtained from: Chelsio Communications

cxgbe(4): major tx rework. a) Front load as much work as possible in if_transmit, before any driver lock or software queue has to get involved. b) Replace buf_ring with a brand new mp_ring (multiproducer ring). This is specifically for the tx multiqueue model where one of the if_transmit producer threads becomes the consumer and other producers carry on as usual. mp_ring is implemented as standalone code and it should be possible to use it in any driver with tx multiqueue. It also has: - the ability to enqueue/dequeue multiple items. This might become significant if packet batching is ever implemented. - an abdication mechanism to allow a thread to give up writing tx descriptors and have another if_transmit thread take over. A thread that's writing tx descriptors can end up doing so for an unbounded time period if a) there are other if_transmit threads continuously feeding the sofware queue, and b) the chip keeps up with whatever the thread is throwing at it. - accurate statistics about interesting events even when the stats come at the expense of additional branches/conditional code. The NIC txq lock is uncontested on the fast path at this point. I've left it there for synchronization with the control events (interface up/down, modload/unload). c) Add support for "type 1" coalescing work request in the normal NIC tx path. This work request is optimized for frames with a single item in the DMA gather list. These are very common when forwarding packets. Note that netmap tx in cxgbe already uses these "type 1" work requests. d) Do not request automatic cidx updates every 32 descriptors. Instead, request updates via bits in individual work requests (still every 32 descriptors approximately). Also, request an automatic final update when the queue idles after activity. This means NIC tx reclaim is still performed lazily but it will catch up quickly as soon as the queue idles. This seems to be the best middle ground and I'll probably do something similar for netmap tx as well. e) Implement a faster tx path for WRQs (used by TOE tx and control queues, _not_ by the normal NIC tx). Allow work requests to be written directly to the hardware descriptor ring if room is available. I will convert t4_tom and iw_cxgbe modules to this faster style gradually. MFC after: 2 months

cxgbe(4): major tx rework. a) Front load as much work as possible in if_transmit, before any driver lock or software queue has to get involved. b) Replace buf_ring with a brand new mp_ring (multiproducer ring). This is specifically for the tx multiqueue model where one of the if_transmit producer threads becomes the consumer and other producers carry on as usual. mp_ring is implemented as standalone code and it should be possible to use it in any driver with tx multiqueue. It also has: - the ability to enqueue/dequeue multiple items. This might become significant if packet batching is ever implemented. - an abdication mechanism to allow a thread to give up writing tx descriptors and have another if_transmit thread take over. A thread that's writing tx descriptors can end up doing so for an unbounded time period if a) there are other if_transmit threads continuously feeding the sofware queue, and b) the chip keeps up with whatever the thread is throwing at it. - accurate statistics about interesting events even when the stats come at the expense of additional branches/conditional code. The NIC txq lock is uncontested on the fast path at this point. I've left it there for synchronization with the control events (interface up/down, modload/unload). c) Add support for "type 1" coalescing work request in the normal NIC tx path. This work request is optimized for frames with a single item in the DMA gather list. These are very common when forwarding packets. Note that netmap tx in cxgbe already uses these "type 1" work requests. d) Do not request automatic cidx updates every 32 descriptors. Instead, request updates via bits in individual work requests (still every 32 descriptors approximately). Also, request an automatic final update when the queue idles after activity. This means NIC tx reclaim is still performed lazily but it will catch up quickly as soon as the queue idles. This seems to be the best middle ground and I'll probably do something similar for netmap tx as well. e) Implement a faster tx path for WRQs (used by TOE tx and control queues, _not_ by the normal NIC tx). Allow work requests to be written directly to the hardware descriptor ring if room is available. I will convert t4_tom and iw_cxgbe modules to this faster style gradually. MFC after: 2 months

Fix some bad interaction between cxgbe(4) and lacp lagg(4) that could leave a port permanently disabled when a copper cable is unplugged and then plugged right back in. lacp_linkstate goes looking for the current ifmedia on a link state change and it could get stale information from cxgbe(4) on a module unplug followed by replug. The fix is to process module events before link-state events within the driver, and to always rebuild the ifmedia list on a module change event (instead of rebuilding it lazily). Thanks to asomers@ for the problem report and detailed analysis to go with it. MFC after: 1 week

T4 packet filtering/steering. - Enable 5-tuple and every-packet lookup. - Setup the default filter mode to allow filtering/steering based on IP protocol, ingress port, inner VLAN ID, IP frag, FCoE, and MPS match type; all combined together. You can also filter based on MAC index, Ethernet type, IP TOS/IPv6 Traffic Class, and outer VLAN ID but you'll have to modify the default filter mode and exclude some of the match-fields in it. IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter rules. - Add driver ioctls to get/set the global filter mode. - Add driver ioctls to program and delete hardware filters. A couple of the "switch" actions that rewrite Ethernet and VLAN information and switch the packet out of another port may not work as the L2 code is not yet in place. Everything else, including all "drop" and "pass" rules with RSS or absolute qid, should work. Obtained from: Chelsio Communications

cxgbe(4): major tx rework. a) Front load as much work as possible in if_transmit, before any driver lock or software queue has to get involved. b) Replace buf_ring with a brand new mp_ring (multiproducer ring). This is specifically for the tx multiqueue model where one of the if_transmit producer threads becomes the consumer and other producers carry on as usual. mp_ring is implemented as standalone code and it should be possible to use it in any driver with tx multiqueue. It also has: - the ability to enqueue/dequeue multiple items. This might become significant if packet batching is ever implemented. - an abdication mechanism to allow a thread to give up writing tx descriptors and have another if_transmit thread take over. A thread that's writing tx descriptors can end up doing so for an unbounded time period if a) there are other if_transmit threads continuously feeding the sofware queue, and b) the chip keeps up with whatever the thread is throwing at it. - accurate statistics about interesting events even when the stats come at the expense of additional branches/conditional code. The NIC txq lock is uncontested on the fast path at this point. I've left it there for synchronization with the control events (interface up/down, modload/unload). c) Add support for "type 1" coalescing work request in the normal NIC tx path. This work request is optimized for frames with a single item in the DMA gather list. These are very common when forwarding packets. Note that netmap tx in cxgbe already uses these "type 1" work requests. d) Do not request automatic cidx updates every 32 descriptors. Instead, request updates via bits in individual work requests (still every 32 descriptors approximately). Also, request an automatic final update when the queue idles after activity. This means NIC tx reclaim is still performed lazily but it will catch up quickly as soon as the queue idles. This seems to be the best middle ground and I'll probably do something similar for netmap tx as well. e) Implement a faster tx path for WRQs (used by TOE tx and control queues, _not_ by the normal NIC tx). Allow work requests to be written directly to the hardware descriptor ring if room is available. I will convert t4_tom and iw_cxgbe modules to this faster style gradually. MFC after: 2 months

Add support for packet-sniffing tracers to cxgbe(4). This works with all T4 and T5 based cards and is useful for analyzing TSO, LRO, TOE, and for general purpose monitoring without tapping any cxgbe or cxl ifnet directly. Tracers on the T4/T5 chips provide access to Ethernet frames exactly as they were received from or transmitted on the wire. On transmit, a tracer will capture a frame after TSO segmentation, hw VLAN tag insertion, hw L3 & L4 checksum insertion, etc. It will also capture frames generated by the TCP offload engine (TOE traffic is normally invisible to the kernel). On receive, a tracer will capture a frame before hw VLAN extraction, runt filtering, other badness filtering, before the steering/drop/L2-rewrite filters or the TOE have had a go at it, and of course before sw LRO in the driver. There are 4 tracers on a chip. A tracer can trace only in one direction (tx or rx). For now cxgbetool will set up tracers to capture the first 128B of every transmitted or received frame on a given port. This is a small subset of what the hardware can do. A pseudo ifnet with the same name as the nexus driver (t4nex0 or t5nex0) will be created for tracing. The data delivered to this ifnet is an additional copy made inside the chip. Normal delivery to cxgbe<n> or cxl<n> will be made as usual. /* watch cxl0, which is the first port hanging off t5nex0. */ # cxgbetool t5nex0 tracer 0 tx0 (watch what cxl0 is transmitting) # cxgbetool t5nex0 tracer 1 rx0 (watch what cxl0 is receiving) # cxgbetool t5nex0 tracer list # tcpdump -i t5nex0 <== all that cxl0 sees and puts on the wire If you were doing TSO, a tcpdump on cxl0 may have shown you ~64K "frames" with no L3/L4 checksum but this will show you the frames that were actually transmitted. /* all done */ # cxgbetool t5nex0 tracer 0 disable # cxgbetool t5nex0 tracer 1 disable # cxgbetool t5nex0 tracer list # ifconfig t5nex0 destroy

Many updates to cxgbe(4) - Device configuration via plain text config file. Also able to operate when not attached to the chip as the master driver. - Generic "work request" queue that serves as the base for both ctrl and ofld tx queues. - Generic interrupt handler routine that can process any event on any kind of ingress queue (via a dispatch table). - A couple of new driver ioctls. cxgbetool can now install a firmware to the card ("loadfw" command) and can read the card's memory ("memdump" and "tcb" commands). - Lots of assorted information within dev.t4nex.X.misc.* This is primarily for debugging and won't show up in sysctl -a. - Code to manage the L2 tables on the chip. - Updates to cxgbe(4) man page to go with the tunables that have changed. - Updates to the shared code in common/ - Updates to the driver-firmware interface (now at fw 1.4.16.0) MFC after: 1 month

Change t4_list_lock and t4_uld_list_lock from mutexes to sx'es. - tom_uninit had to be reworked not to hold the adapter lock (a mutex) around t4_deactivate_uld, which acquires the uld_list_lock. - the ifc_match for the interface cloner that creates the tracer ifnet had to be reworked as the kernel calls ifc_match with the global if_cloners_mtx held.

cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size. T4 gear is totally untested. trantor:~# ./pkt-gen -i ncxl0 -f tx -D 00:07:43:ab:cd:ef 881.952141 main [1621] interface is ncxl0 881.952250 extract_ip_range [275] range is 10.0.0.1:0 to 10.0.0.1:0 881.952253 extract_ip_range [275] range is 10.1.0.1:0 to 10.1.0.1:0 881.962540 main [1804] mapped 334980KB at 0x801dff000 Sending on netmap:ncxl0: 4 queues, 1 threads and 1 cpus. 10.0.0.1 -> 10.1.0.1 (00:00:00:00:00:00 -> 00:07:43:ab:cd:ef) 881.962562 main [1882] Sending 512 packets every 0.000000000 s 881.962563 main [1884] Wait 2 secs for phy reset 884.088516 main [1886] Ready... 884.088535 nm_open [457] overriding ifname ncxl0 ringid 0x0 flags 0x1 884.088607 sender_body [996] start 884.093246 sender_body [1064] drop copy 885.090435 main_thread [1418] 45206353 pps (45289533 pkts in 1001840 usec) 886.091600 main_thread [1418] 45322792 pps (45375593 pkts in 1001165 usec) 887.092435 main_thread [1418] 45313992 pps (45351784 pkts in 1000834 usec) 888.094434 main_thread [1418] 45315765 pps (45406397 pkts in 1002000 usec) 889.095434 main_thread [1418] 45333218 pps (45378551 pkts in 1001000 usec) 890.097434 main_thread [1418] 45315247 pps (45405877 pkts in 1002000 usec) 891.099434 main_thread [1418] 45326515 pps (45417168 pkts in 1002000 usec) 892.101434 main_thread [1418] 45333039 pps (45423705 pkts in 1002000 usec) 893.103434 main_thread [1418] 45324105 pps (45414708 pkts in 1001999 usec) 894.105434 main_thread [1418] 45318042 pps (45408723 pkts in 1002001 usec) 895.106434 main_thread [1418] 45332430 pps (45377762 pkts in 1001000 usec) 896.107434 main_thread [1418] 45338072 pps (45383410 pkts in 1001000 usec) ...

cxgbe(4): Keep track of the clusters that have to be freed by the custom free routine (rxb_free) in the driver. Fail MOD_UNLOAD with EBUSY if any such cluster has been handed up to the kernel but hasn't been freed yet. This prevents a panic later when the cluster finally needs to be freed but rxb_free is gone from the kernel. MFC after: 1 week

Many updates to cxgbe(4) - Device configuration via plain text config file. Also able to operate when not attached to the chip as the master driver. - Generic "work request" queue that serves as the base for both ctrl and ofld tx queues. - Generic interrupt handler routine that can process any event on any kind of ingress queue (via a dispatch table). - A couple of new driver ioctls. cxgbetool can now install a firmware to the card ("loadfw" command) and can read the card's memory ("memdump" and "tcb" commands). - Lots of assorted information within dev.t4nex.X.misc.* This is primarily for debugging and won't show up in sysctl -a. - Code to manage the L2 tables on the chip. - Updates to cxgbe(4) man page to go with the tunables that have changed. - Updates to the shared code in common/ - Updates to the driver-firmware interface (now at fw 1.4.16.0) MFC after: 1 month

cxgbe(4): Add support for Chelsio's Terminator 5 (aka T5) ASIC. This includes support for the NIC and TOE features of the 40G, 10G, and 1G/100M cards based on the T5. The ASIC is mostly backward compatible with the Terminator 4 so cxgbe(4) has been updated instead of writing a brand new driver. T5 cards will show up as cxl (short for cxlgb) ports attached to the t5nex bus driver. Sponsored by: Chelsio
