Title:
Guest hangs during option rom loading with certain cards
Status in QEMU:
Fix Released
Bug description:
With a Broadcom Corporation NetXtreme II BCM57810 10 Gigabit Ethernet
card, device assignment does not work. The guest hangs during option
rom execution. Moreover, if an attempt is made to quit qemu when the
guest is in the hung state, the card gets into an inoperable state.
Only a powercycle then, restores the card back into working order,
just unloading/loading the driver does not help.
Qemu version - 1.6.2 or current master
Distribution - FC19
Kernel Version - 3.12.9-201.fc19.x86_64
Details of the card -
# ethtool -i p2p2
driver: bnx2x
version: 1.78.17-0
firmware-version: bc 7.8.22
bus-info: 0000:08:00.1
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes
The output of lspci when the card is broken -
03:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM57810 10
Gigabit Ethernet (rev ff) (prog-if ff)
!!! Unknown header type 7f
Kernel driver in use: bnx2x

I will post if I get a chance to try out a newer than 7.8.22 for the
option rom and see if this issue is fixed. However it appears we need
to have a unified approach to automatically avoid loading the rom
based on certain criteria. Manually, looking out for fixes to
firmware and hard coding decisions based on those is neither desirable
nor easy to maintain.
