I (and a lot of other users) have been experiencing the frequent sky2
transmit timeout problem [1] (on 88E8053/Yukon2 EC gig hardware); this
is a result of the embedded NIC controller locking up, and I've found
that updating the firmware addresses this issue. I'm still seeing a
previous and different issue [2] from time to time though (silicon
bug?).
Thanks for the info. I've been dealing with this problem for some long
time, hopefully sky driver from the latest kernels is able to recover
from such hangs, so it is not that critical problem now.
Marvell shipping broken firmware is completely unpublicised or
acknowledged, however updated firmware is available through your
motherboard vendor, so all hope it not lost after all...
Unfortunately not through all vendors. :( Or maybe not *yet*?
My 8053/EC is using firmware 2.2 (previously 1.9) - you can check in
DOS with 'yukondg.exe' from
http://www.marvell.com/drivers/files/yukondg_v6.53.4.3.zip .
Stephen, is it possible for sky2 driver to check and print the
firmware version?
It is possible to dump and program eeprom from linux, and the version
maybe buried in the VPD, but some hardware has non-functional VPD.
The revision number in the VPD matches the revision number (from PCI)
that is already printed by the driver. Since I don't have enough documentation
on the firmware to know the format, there is no way to print anything
really useful.
$ lspci -d11ab:
02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053
PCI-E Gigabit Ethernet Controller (rev 22)
07:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8036
PCI-E Fast Ethernet Controller (rev 15)
$ dmesg | grep sky2.*rev
[ 33.998133] sky2 0000:02:00.0: v1.20 addr 0xd6000000 irq 16
Yukon-EC (0xb6) rev 2
[ 33.999085] sky2 0000:07:00.0: v1.20 addr 0xd8000000 irq 18
Yukon-FE (0xb7) rev 1
The 'rev' reported by the driver is from:
hw->chip_rev = (sky2_read8(hw, B2_MAC_CFG) & CFG_CHIP_R_MSK) >> 4;
which is the chip/silicon revision, whereas the rev reported by the
PCI device is the firmware revision, as you've found.
How about:
02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053
PCI-E Gigabit Ethernet Controller (silicon rev 2, firmware/PCI rev 22)
This introduces perhaps something even more useful - we know there are
really major issues with (eg) 88E8053 before firmware 2.2; is it worth
adding a warning, such as:
sky2: firmware earlier than rev 2.2 detected - if you experience
transmit timeouts, ask vendor for 88E8053 firmware update
There are a lot of bug reports on the web pointing the finger at the
sky2 driver, and waiting for a 'fixed' version, but the issue is
elsewhere...part of the problem, if there is (almost) no
documentation/evidence of this problem posted anywhere.
Many thanks,
Daniel
lspci reports PCI rev. driver reports chip rev.
But the PCI revision is also the firmware revision - I didn't know
this until you mentioned it, so it would be handy to make it explicit
in the driver's output; also we don't always have the 'lspci' output
in bug reports. Let me know if you'd like a patch...
If this is correct then I have hideously old version the firmware:
02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 15)
Is it possible/safe to use the firmware privided by Gigabyte/Jetway to
flash chipset in mainboards from other vendors?
Best regards,
Krzysztof Olędzki
