Net and virtio problem with QEMU 0.10.0 and coreboot v2

[rukhsana ansari]

Hi,

Software used :
qemu-0.10.0, coreboot-v2, filo(latest svn version), fedora9 image

Problem encountered:
qemu boots Fedora9 image successfully. However, the ethernet interface isn't
up and dmesg shows an irq problem.

Thhings tried out:
I've tried pci=biosirq and problems still remains.
I've also patched with the qemu bios patch (0.9.1) available at:
http://www.mail-archive.com/[e-mail]/msg01771.html
However, I haven't applied the other patches that are meant for 0.9 and
available at

ttp://www.coreboot.org/QEMU_Build_Tutorial#Building_Qemu
http://www.coreboot.org/QEMU_Build_Tutorial#Building_Qemu
because the code difference with 0.10.0

Any suggestions from coreboot experts on howto proceed to resolve this issue?

The following is an edited version of dmesg that shows an irq problem:

Net and virtio problem with QEMU 0.10.0 and coreboot v2

I wonder if qemu changed how they are "routing" IRQs.

Can you boot and run getpir and we can compare what you get vs. what
is in the existing v2 tables?

Sorry, couldn't run it from Linux.
Can you give me the instructions on when and how to run it?

send me your errors. It should "just work" when run as root.

Not sure if this is the procedure:
I copied util/getpir to the fedora9 image, booted qemu with that image and
ran getpir.
Got the following error:
Probing PIRQ table in memory.
No PCI IRQ routing table signature found.

well that does explain the other error.

I'm sorry, my fault; this is under coreboot or under the standard qemu
bios? I'd like to see it from the standard.

Ron,

The following was the irq_tables.c file created when getpir was run with
QEMU using its default Bochs BIOS.

Rukhsana, please test qemu again with v2. The qemu problem should be fixed.
