|
|
* Broadcom BCM57xx(x)/BCM590x NetXtreme and NetLink family Ethernet driver
|
2003-04-03 21:36:33 +00:00
|
|
|
*
|
2001-09-27 23:55:28 +00:00
|
|
|
* The Broadcom BCM5700 is based on technology originally developed by
|
2013-01-26 00:11:39 +00:00
|
|
|
* Alteon Networks as part of the Tigon I and Tigon II Gigabit Ethernet
|
2011-05-02 21:04:23 +00:00
|
|
|
* MAC chips. The BCM5700, sometimes referred to as the Tigon III, has
|
2001-09-27 23:55:28 +00:00
|
|
|
* two on-board MIPS R4000 CPUs and can have as much as 16MB of external
|
|
|
|
* SSRAM. The BCM5700 supports TCP, UDP and IP checksum offload, jumbo
|
|
|
|
* frames, highly configurable RX filtering, and 16 RX and TX queues
|
|
|
|
* (which, along with RX filter rules, can be used for QOS applications).
|
|
|
|
* Other features, such as TCP segmentation, may be available as part
|
|
|
|
* of value-added firmware updates. Unlike the Tigon I and Tigon II,
|
|
|
|
* firmware images can be stored in hardware and need not be compiled
|
|
|
|
* into the driver.
|
|
|
|
*
|
|
|
|
* The BCM5700 supports the PCI v2.2 and PCI-X v1.0 standards, and will
|
|
|
|
* function in a 32-bit/64-bit 33/66Mhz bus, or a 64-bit/133Mhz bus.
|
2004-10-30 14:54:51 +00:00
|
|
|
*
|
2001-09-27 23:55:28 +00:00
|
|
|
* The BCM5701 is a single-chip solution incorporating both the BCM5700
|
2002-03-22 06:45:40 +00:00
|
|
|
* MAC and a BCM5401 10/100/1000 PHY. Unlike the BCM5700, the BCM5701
|
2001-09-27 23:55:28 +00:00
|
|
|
* does not support external SSRAM.
|
|
|
|
*
|
|
|
|
* Broadcom also produces a variation of the BCM5700 under the "Altima"
|
|
|
|
* brand name, which is functionally similar but lacks PCI-X support.
|
|
|
|
*
|
|
|
|
* Without external SSRAM, you can only have at most 4 TX rings,
|
|
|
|
* and the use of the mini RX ring is disabled. This seems to imply
|
|
|
|
* that these features are simply not available on the BCM5701. As a
|
|
|
|
* result, this driver does not implement any support for the mini RX
|
|
|
|
* ring.

A big rewrite of receive Jumbo frame handling. Remove the local Jumbo
cluster allocator, that wasn't MPSAFE. Instead, utilize our new generic
UMA jumbo cluster allocator. Since UMA gives us a 9k piece that is contigous
in virtual memory, but isn't contigous in physical memory we need to handle
a few segments. To deal with this we utilize Tigon chip feature - extended
RX descriptors, that can handle up to four DMA segments for one frame.
Details:
o Remove bge_alloc_jumbo_mem(), bge_free_jumbo_mem(),
bge_jalloc(), bge_jfree() functions.
o Remove SLIST heads, bge_jumbo_tag, bge_jumbo_map from softc.
o Use extended RX BDs for Jumbo receive producer ring, and
initialize it appropriately.
o New bge_newbuf_jumbo():
- Allocate an mbuf with Jumbo cluster with help of m_cljget().
- Load the cluster for DMA with help of bus_dmamap_load_mbuf_sg().
- Assert that we got 3 segments in the DMA mapping.
- Fill in these 3 segments into the extended RX descriptor.

A big rewrite of receive Jumbo frame handling. Remove the local Jumbo
cluster allocator, that wasn't MPSAFE. Instead, utilize our new generic
UMA jumbo cluster allocator. Since UMA gives us a 9k piece that is contigous
in virtual memory, but isn't contigous in physical memory we need to handle
a few segments. To deal with this we utilize Tigon chip feature - extended
RX descriptors, that can handle up to four DMA segments for one frame.
Details:
o Remove bge_alloc_jumbo_mem(), bge_free_jumbo_mem(),
bge_jalloc(), bge_jfree() functions.
o Remove SLIST heads, bge_jumbo_tag, bge_jumbo_map from softc.
o Use extended RX BDs for Jumbo receive producer ring, and
initialize it appropriately.
o New bge_newbuf_jumbo():
- Allocate an mbuf with Jumbo cluster with help of m_cljget().
- Load the cluster for DMA with help of bus_dmamap_load_mbuf_sg().
- Assert that we got 3 segments in the DMA mapping.
- Fill in these 3 segments into the extended RX descriptor.

Try to sort out the correct way to generate async link state change
interrupts. This is a bit harder than it needs to be because there's
more than one way to generate link attentions, at least one of which
does not work on the BCM5700, but does on the 5701.
For the 5701, we can safely use the 'link changed' bit in the status
block, and we enable link change attentions in the mac event register.
For the 5700, we have to use MII interrupts, which require checking
the MAC status register rather than the status block. This requires
doing an extra register access on each interrupt which I'd prefer to
avoid, but them's the breaks. Testing with both a 3c996-T and 3c996B-T
shows that we do in fact detect the link going up and down properly
on cable insertions/disconnections.
Also, avoid twiddling the autopoll enable bit in the MI mode register
when doing a PHY read. I think this coupled with the other changes
will stop the interrupt storms Paul Saab has been harassing me about.
Manually setting the link to 100baseTX full duplex seems to work ok
for me. (I'm typing over the 3c996B-T right now.)
Lastly, teach the driver how to recognize a 3c996B-SX by checking
the hardware config word in the EEPROM in order to detect the media.
We attach 5701 fiber cards correctly now, but I haven't verified that
they send/receive packets yet since I don't have a second fiber
interface at home. (I know that fiber 5700 cards work, so I'm
keeping my fingers crossed.)

A big rewrite of receive Jumbo frame handling. Remove the local Jumbo
cluster allocator, that wasn't MPSAFE. Instead, utilize our new generic
UMA jumbo cluster allocator. Since UMA gives us a 9k piece that is contigous
in virtual memory, but isn't contigous in physical memory we need to handle
a few segments. To deal with this we utilize Tigon chip feature - extended
RX descriptors, that can handle up to four DMA segments for one frame.
Details:
o Remove bge_alloc_jumbo_mem(), bge_free_jumbo_mem(),
bge_jalloc(), bge_jfree() functions.
o Remove SLIST heads, bge_jumbo_tag, bge_jumbo_map from softc.
o Use extended RX BDs for Jumbo receive producer ring, and
initialize it appropriately.
o New bge_newbuf_jumbo():
- Allocate an mbuf with Jumbo cluster with help of m_cljget().
- Load the cluster for DMA with help of bus_dmamap_load_mbuf_sg().
- Assert that we got 3 segments in the DMA mapping.
- Fill in these 3 segments into the extended RX descriptor.

Try to sort out the correct way to generate async link state change
interrupts. This is a bit harder than it needs to be because there's
more than one way to generate link attentions, at least one of which
does not work on the BCM5700, but does on the 5701.
For the 5701, we can safely use the 'link changed' bit in the status
block, and we enable link change attentions in the mac event register.
For the 5700, we have to use MII interrupts, which require checking
the MAC status register rather than the status block. This requires
doing an extra register access on each interrupt which I'd prefer to
avoid, but them's the breaks. Testing with both a 3c996-T and 3c996B-T
shows that we do in fact detect the link going up and down properly
on cable insertions/disconnections.
Also, avoid twiddling the autopoll enable bit in the MI mode register
when doing a PHY read. I think this coupled with the other changes
will stop the interrupt storms Paul Saab has been harassing me about.
Manually setting the link to 100baseTX full duplex seems to work ok
for me. (I'm typing over the 3c996B-T right now.)
Lastly, teach the driver how to recognize a 3c996B-SX by checking
the hardware config word in the EEPROM in order to detect the media.
We attach 5701 fiber cards correctly now, but I haven't verified that
they send/receive packets yet since I don't have a second fiber
interface at home. (I know that fiber 5700 cards work, so I'm
keeping my fingers crossed.)

|
|
|
|
*
|
|
|
|
* Note: we have to be able to handle two possibilities here:
|
A big rewrite of receive Jumbo frame handling. Remove the local Jumbo
cluster allocator, that wasn't MPSAFE. Instead, utilize our new generic
UMA jumbo cluster allocator. Since UMA gives us a 9k piece that is contigous
in virtual memory, but isn't contigous in physical memory we need to handle
a few segments. To deal with this we utilize Tigon chip feature - extended
RX descriptors, that can handle up to four DMA segments for one frame.
Details:
o Remove bge_alloc_jumbo_mem(), bge_free_jumbo_mem(),
bge_jalloc(), bge_jfree() functions.
o Remove SLIST heads, bge_jumbo_tag, bge_jumbo_map from softc.
o Use extended RX BDs for Jumbo receive producer ring, and
initialize it appropriately.
o New bge_newbuf_jumbo():
- Allocate an mbuf with Jumbo cluster with help of m_cljget().
- Load the cluster for DMA with help of bus_dmamap_load_mbuf_sg().
- Assert that we got 3 segments in the DMA mapping.
- Fill in these 3 segments into the extended RX descriptor.

- Remove attempts to implement setting of BMCR_LOOP/MIIF_NOLOOP
(reporting IFM_LOOP based on BMCR_LOOP is left in place though as
it might provide useful for debugging). For most mii(4) drivers it
was unclear whether the PHYs driven by them actually support
loopback or not. Moreover, typically loopback mode also needs to
be activated on the MAC, which none of the Ethernet drivers using
mii(4) implements. Given that loopback media has no real use (and
obviously hardly had a chance to actually work) besides for driver
development (which just loopback mode should be sufficient for
though, i.e one doesn't necessary need support for loopback media)
support for it is just dropped as both NetBSD and OpenBSD already
did quite some time ago.
- Let mii_phy_add_media() also announce the support of IFM_NONE.
- Restructure the PHY entry points to use a structure of entry points
instead of discrete function pointers, and extend this to include
a "reset" entry point. Make sure any PHY-specific reset routine is
always used, and provide one for lxtphy(4) which disables MII
interrupts (as is done for a few other PHYs we have drivers for).
This includes changing NIC drivers which previously just called the
generic mii_phy_reset() to now actually call the PHY-specific reset
routine, which might be crucial in some cases. While at it, the
redundant checks in these NIC drivers for mii->mii_instance not being
zero before calling the reset routines were removed because as soon
as one PHY driver attaches mii->mii_instance is incremented and we
hardly can end up in their media change callbacks etc if no PHY driver
has attached as mii_attach() would have failed in that case and not
attach a miibus(4) instance.
Consequently, NIC drivers now no longer should call mii_phy_reset()
directly, so it was removed from EXPORT_SYMS.
- Add a mii_phy_dev_attach() as a companion helper to mii_phy_dev_probe().
The purpose of that function is to perform the common steps to attach
a PHY driver instance and to hook it up to the miibus(4) instance and to
optionally also handle the probing, addition and initialization of the
supported media. So all a PHY driver without any special requirements
has to do in its bus attach method is to call mii_phy_dev_attach()
along with PHY-specific MIIF_* flags, a pointer to its PHY functions
and the add_media set to one. All PHY drivers were updated to take
advantage of mii_phy_dev_attach() as appropriate. Along with these
changes the capability mask was added to the mii_softc structure so
PHY drivers taking advantage of mii_phy_dev_attach() but still
handling media on their own do not need to fiddle with the MII attach
arguments anyway.
- Keep track of the PHY offset in the mii_softc structure. This is done
for compatibility with NetBSD/OpenBSD.
- Keep track of the PHY's OUI, model and revision in the mii_softc
structure. Several PHY drivers require this information also after
attaching and previously had to wrap their own softc around mii_softc.
NetBSD/OpenBSD also keep track of the model and revision on their
mii_softc structure. All PHY drivers were updated to take advantage
as appropriate.
- Convert the mebers of the MII data structure to unsigned where
appropriate. This is partly inspired by NetBSD/OpenBSD.
- According to IEEE 802.3-2002 the bits actually have to be reversed
when mapping an OUI to the MII ID registers. All PHY drivers and
miidevs where changed as necessary. Actually this now again allows to
largely share miidevs with NetBSD, which fixed this problem already
9 years ago. Consequently miidevs was synced as far as possible.
- Add MIIF_NOMANPAUSE and mii_phy_flowstatus() calls to drivers that
weren't explicitly converted to support flow control before. It's
unclear whether flow control actually works with these but typically
it should and their net behavior should be more correct with these
changes in place than without if the MAC driver sets MIIF_DOPAUSE.
