virtio: support specification 1.0
Modern (v1.0) virtio pci device defines several pci capabilities.
Each cap has a configure structure corresponding to it, and the
cap.bar and cap.offset fields tell us where to find it.
Firstly, we map the pci resources by rte_eal_pci_map_device().
We then could easily locate a cfg structure by:
cfg_addr = dev->mem_resources[cap.bar].addr + cap.offset;
Therefore, the entrance of enabling modern (v1.0) pci device support
is to iterate the pci capability lists, and to locate some configs
we care; and they are:
- common cfg
For generic virtio and virtqueue configuration, such as setting/getting
features, enabling a specific queue, and so on.
- nofity cfg
Combining with `queue_notify_off' from common cfg, we could use it to
notify a specific virt queue.
- device cfg
Where virtio_net_config structure is located.
- isr cfg
Where to read isr (interrupt status).
If any of above cap is not found, we fallback to the legacy virtio
handling.
If succeed, hw->vtpci_ops is assigned to modern_ops, where all
operations are implemented by reading/writing a (or few) specific
configuration space from above 4 cfg structures. And that's basically
how this patch works.
Besides those changes, virtio 1.0 introduces a new status field:
FEATURES_OK, which is set after features negotiation is done.
Last, set the VIRTIO_F_VERSION_1 feature flag.

|
* **Virtio 1.0.**
|
|
|
|
|
|
|
|
|
|
|
|
Enabled virtio 1.0 support for virtio pmd driver.
|
|
|

|
|
|
|
* **Supported virtio for ARM.**
|
|
|
|
|
|
|
|
|
|
|
|
Enabled virtio support for armv7/v8. Tested for arm64.
|
|
|
|
|
|
Virtio for arm support VFIO-noiommu mode only.
|
|
|
|
|
|
Virtio can work with other non-x86 arch too like powerpc.
|
|
|
|
|
|

2016-02-05 07:31:38 +00:00
|
|
|
|
* **Supported virtio offload in vhost-user.**
|
|
|
|
|
|
|
vhost: add guest offload setting
Add guest offload setting in vhost lib.
Virtio 1.0 spec (5.1.6.4 Processing of Incoming Packets) says:
1. If the VIRTIO_NET_F_GUEST_CSUM feature was negotiated, the
VIRTIO_NET_HDR_F_NEEDS_CSUM bit in flags can be set: if so,
the packet checksum at offset csum_offset from csum_start
and any preceding checksums have been validated. The checksum
on the packet is incomplete and csum_start and csum_offset
indicate how to calculate it (see Packet Transmission point 1).
2. If the VIRTIO_NET_F_GUEST_TSO4, TSO6 or UFO options were
negotiated, then gso_type MAY be something other than
VIRTIO_NET_HDR_GSO_NONE, and gso_size field indicates the
desired MSS (see Packet Transmission point 2).
In order to support these features, the following changes are added,
1. Extend 'VHOST_SUPPORTED_FEATURES' macro to add the offload features negotiation.
2. Enqueue these offloads: convert some fields in mbuf to the fields in virtio_net_hdr.
There are more explanations for the implementation.
For VM2VM case, there is no need to do checksum, for we think the
data should be reliable enough, and setting VIRTIO_NET_HDR_F_NEEDS_CSUM
at RX side will let the TCP layer to bypass the checksum validation,
so that the RX side could receive the packet in the end.
In terms of us-vhost, at vhost RX side, the offload information is
inherited from mbuf, which is in turn inherited from TX side. If we
can still get those info at RX side, it means the packet is from
another VM at same host. So, it's safe to set the
VIRTIO_NET_HDR_F_NEEDS_CSUM, to skip checksum validation.

|
|
|
Add the offload and negotiation of checksum and TSO between vhost-user and
|
2016-02-05 07:31:38 +00:00
|
|
|
|
vanilla Linux virtio guest.
|
|
|
|
|
|
|
2016-01-29 04:58:02 +00:00
|
|
|
|
* **Added vhost-user live migration support.**
|
|
|
|
|
|
|
2016-02-14 06:24:47 +00:00
|
|
|
|
* **Added multicast promiscuous mode support on VF for ixgbe.**
|
|
|
|
|
|
|
|
|
|
|
|
Added multicast promiscuous mode support on ixgbe VF driver. So all the VFs
|
|
|
|
|
|
can receive the multicast packets.
|
|
|
|
|
|
|
|
|
|
|
|
Please note if we want to use this promiscuous mode, we need both PF and VF
|
|
|
|
|
|
driver to support it. The reason is this VF feature is configured on PF.
|
|
|
|
|
|
If use kernel PF driver + dpdk VF driver, make sure kernel PF driver support
|
|
|
|
|
|
VF multicast promiscuous mode. If use dpdk PF + dpdk VF, better make sure PF
|
|
|
|
|
|
driver is the same version as VF.
|
|
|
|
|
|
|
2016-03-11 01:10:09 +00:00
|
|
|
|
* **Added support for E-tag on X550.**
|
|
|
|
|
|
|
|
|
|
|
|
E-tag is defined in 802.1br. Please reference
|
|
|
|
|
|
http://www.ieee802.org/1/pages/802.1br.html.
|
|
|
|
|
|
|
|
|
|
|
|
This feature is for VF, but the settings are on PF. It means
|
|
|
|
|
|
the CLIs should be used on PF, but some of their effects will be shown on VF.
|
|
|
|
|
|
The forwarding of E-tag packets based on GRP and E-CID_base will have effect
|
|
|
|
|
|
on PF. Theoretically the E-tag packets can be forwarded to any pool/queue.
|
|
|
|
|
|
But normally we'd like to forward the packets to the pools/queues belonging
|
|
|
|
|
|
to the VFs. And E-tag insertion and stripping will have effect on VFs. When
|
|
|
|
|
|
VF receives E-tag packets, it should strip the E-tag. When VF transmits
|
|
|
|
|
|
packets, it should insert the E-tag. Both can be offloaded.
|
|
|
|
|
|
|
|
|
|
|
|
When we want to use this E-tag support feature, the forwarding should be
|
|
|
|
|
|
enabled to forward the packets received by PF to indicated VFs. And insertion
|
|
|
|
|
|
and stripping should be enabled for VFs to offload the effort to HW.
|
|
|
|
|
|
|
|
|
|
|
|
* Support E-tag offloading of insertion and stripping.
|
|
|
|
|
|
* Support Forwarding E-tag packets to pools based on
|
|
|
|
|
|
GRP and E-CID_base.

|
|
|
|
|
|
2016-03-10 02:42:14 +00:00
|
|
|
|
* **Added support for VxLAN & NVGRE checksum off-load on X550.**
|
|
|
|
|
|
|
|
|
|
|
|
* Added support for VxLAN & NVGRE RX/TX checksum off-load on
|
|
|
|
|
|
X550. RX/TX checksum off-load is provided on both inner and
|
|
|
|
|
|
outer IP header and TCP header.
|
|
|
|
|
|
* Added functions to support VxLAN port configuration. The
|
|
|
|
|
|
default VxLAN port number is 4789 but this can be updated
|
|
|
|
|
|
programmatically.
|
|
|
|
|
|
|
2016-02-14 08:54:56 +00:00
|
|
|
|
* **Added new X550EM_a devices.**
|
|
|
|
|
|
|
|
|
|
|
|
Added new X550EM_a devices and their mac types, X550EM_a and X550EM_a_vf.
|
|
|
|
|
|
Updated the code to use the new devices and mac types.
|
|
|
|
|
|
|
2016-02-14 08:54:57 +00:00
|
|
|
|
* **Added x550em_x V2 device support.**
|
|
|
|
|
|
|
|
|
|
|
|
Only x550em_x V1 was supported before. Now V2 is supported.
|
|
|
|
|
|
A mask for V1 and V2 is defined and used to support both.
|
|
|
|
|
|
|
2016-02-26 03:05:29 +00:00
|
|
|
|
* **Supported link speed auto-negotiation on X550EM_X**
|
|
|
|
|
|
|
|
|
|
|
|
Normally the auto-negotiation is supported by FW. SW need not care about
|
|
|
|
|
|
that. But on x550em_x, FW doesn't support auto-neg. As the ports of x550em_x
|
|
|
|
|
|
are 10G, if we connect the port with a peer which is 1G, the link will always
|
|
|
|
|
|
be down.
|
|
|
|
|
|
We added the support of auto-neg by SW to avoid this link down issue.
|
|
|
|
|
|
|
2016-02-14 08:54:58 +00:00
|
|
|
|
* **Added sw-firmware sync on X550EM_a.**
|
|
|
|
|
|
|
|
|
|
|
|
Added support for sw-firmware sync for resource sharing.
|
|
|
|
|
|
Use the PHY token, shared between sw-fw for PHY access on X550EM_a.
|
|
|
|
|
|
|
2016-03-08 08:14:35 +00:00
|
|
|
|
* **Updated the i40e base driver.**
|
|
|
|
|
|
|
|
|
|
|
|
The i40e base driver was updated with changes including the
|
|
|
|
|
|
following:
|
|
|
|
|
|
|
|
|
|
|
|
* Use Rx control AQ commands to read/write Rx control registers.
|
|
|
|
|
|
* Add new X722 device IDs, and removed X710 one was never used.

|
|
|
* **Enabled PCI extended tag for i40e.**
|
|
|
|
|
|
|
|
|
|
|
|
It enabled extended tag by checking and writing corresponding PCI config
|
|
|
|
|
|
space bytes, to boost the performance. In the meanwhile, it deprecated the
|
|
|
|
|
|
legacy way via reading/writing sysfile supported by kernel module igb_uio.

* **ixgbe: Set MDIO speed after MAC reset.**
|
|
|
|
|
|
|
|
|
|
|
|
The MDIO clock speed must be reconfigured after the MAC reset. The MDIO clock
|
|
|
|
|
|
speed becomes invalid, therefore the driver reads invalid PHY register values.
|
|
|
|
|
|
The driver now set the MDIO clock speed prior to initializing PHY ops and
|
|
|
|
|
|
again after the MAC reset.

|
|
|
* **i40e: Generated MAC address for each VFs.**
|
|
|
|
|
|
|
|
|
|
|
|
It generates a MAC address for each VFs during PF host initialization,
|
|
|
|
|
|
and keeps the VF MAC address the same among different VF launch.

|
|
|
* **i40e: Fixed failure of reading/writing Rx control registers.**
|
|
|
|
|
|
|
|
|
|
|
|
Fixed i40e issue of failing to read/write rx control registers when
|
|
|
|
|
|
under stress with traffic, which might result in application launch
|
|
|
|
|
|
failure.

|
|
|
* **aesni_mb: Fixed wrong return value when creating a device.**
|
|
|
|
|
|
|
|
|
|
|
|
cryptodev_aesni_mb_init() was returning the device id of the device created,
|
|
|
|
|
|
instead of 0 (when success), that rte_eal_vdev_init() expects.
|
|
|
|
|
|
This made impossible the creation of more than one aesni_mb device
|
|
|
|
|
|
from command line.

|
|
|
|
* **qat: Fixed AES GCM decryption.**
|
|
|
|
|
|
|
|
|
|
|
|
Allowed AES GCM on the cryptodev API, but in some cases gave invalid results
|
|
|
|
|
|
due to incorrect IV setting.

* **hash: Fixed CRC32c hash computation for non multiple of 4 bytes sizes.**
|
|
|
|
|
|
|
|
|
|
|
|
Fix crc32c hash functions to return a valid crc32c value for data lengths
|

* **examples/vhost: Fixed frequent mbuf allocation failure.**
|
|
|
|
|
|
|
|
|
|
|
|
vhost-switch often fails to allocate mbuf when dequeue from vring because it
|
|
|

|
wrongly calculates the number of mbufs needed.

|
|
|
|
This section should contain API changes. Sample format:
|
|
|
|
|
|
|
|
|
|
|
|
* Add a short 1-2 sentence description of the API change. Use fixed width
|
|
|
|
|
|
quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
|
|
|
|
|
|
|
2016-03-10 02:42:10 +00:00
|
|
|
|
* The functions ``rte_eth_dev_udp_tunnel_add`` and ``rte_eth_dev_udp_tunnel_delete``
|
|
|
|
|
|
have been renamed into ``rte_eth_dev_udp_tunnel_port_add`` and
|
|
|
|
|
|
``rte_eth_dev_udp_tunnel_port_delete``.
|
|
|
|
|
|
|
2016-03-10 03:05:59 +00:00
|
|
|
|
* The ``outer_mac`` and ``inner_mac`` fields in structure
|
|
|
|
|
|
``rte_eth_tunnel_filter_conf`` are changed from pointer to struct in order
|
|
|
|
|
|
to keep code's readability.
|
|
|
|
|
|
|
2016-03-09 11:59:03 +00:00
|
|
|
|
* The fields in ethdev structure ``rte_eth_fdir_masks`` were changed
|
|
|
|
|
|
to be in big endian.
|
|
|
|
|
|
|
2016-03-11 16:50:57 +00:00
|
|
|
|
* A parameter ``vlan_type`` has been added to the function
|
|
|
|
|
|
``rte_eth_dev_set_vlan_ether_type``.
|
|
|
|
|
|
|
2016-03-09 16:57:15 +00:00
|
|
|
|
* The LPM ``next_hop`` field is extended from 8 bits to 24 bits for IPv4
|
|
|
|
|
|
while keeping ABI compatibility.
|
|
|
|
|
|
|
2016-03-09 16:57:16 +00:00
|
|
|
|
* A new ``rte_lpm_config`` structure is used so LPM library will allocate
|
|
|
|
|
|
exactly the amount of memory which is necessary to hold application’s rules.
|
|
|
|
|
|
The previous ABI is kept for compatibility.

2016-03-08 18:07:48 +00:00
|
|
|
|
* The prototype for the pipeline input port, output port and table action
|
|
|
|
|
|
handlers are updated: the pipeline parameter is added,
|
|
|
|
|
|
the packets mask parameter has been either removed or made input-only.
