Hello all
I tried to enable PCI Passthrough in my Debian Squeeze installation.
Unfortunately, it didnt work. The following bug showed up (excerpt
>from dmesg):
[ 10.148612] uhci_hcd 0000:00:14.2: PCI INT D -> Link[LNKD] -> GSI 11
(level, low) -> IRQ 11
[ 4.678352] Failed to setup GSI :11, err_code:-22
[ 4.678480] dmfe 0000:00:0e.0: PCI INT A -> Link[LNKB] -> GSI 11 (level,
low) -> IRQ 11
[ 6.868419] Failed to setup GSI :10, err_code:-22
That is most strange. Your interrupts are below IRQ 16, and they are level?
They should have been edge, unless you have some strange machine.
Hm... it's a rather old one: Compaq Deskpro PD1006 (Pentium III)
Can you boot the same kernel but without Xen and send the bootup output?
And also the /proc/interrupts (the full one).
This is from Standard debian kernel (2.6.32-5-686):
CPU0
0: 33706 XT-PIC-XT timer
1: 154 XT-PIC-XT i8042
2: 0 XT-PIC-XT cascade
5: 0 XT-PIC-XT ES18xx
6: 3 XT-PIC-XT floppy
7: 1 XT-PIC-XT parport0
8: 0 XT-PIC-XT rtc0
9: 0 XT-PIC-XT acpi
10: 250 XT-PIC-XT eth1
11: 796 XT-PIC-XT uhci_hcd:usb1, eth0
12: 4 XT-PIC-XT i8042
14: 16290 XT-PIC-XT ata_piix
15: 206 XT-PIC-XT ata_piix
NMI: 0 Non-maskable interrupts

TLB: 0 TLB shootdowns
TRM: 0 Thermal event interrupts
THR: 0 Threshold APIC interrupts
MCE: 0 Machine check exceptions
MCP: 2 Machine check polls
ERR: 0
MIS: 0
For dmesg see attachment.
If you don't pass in the card to the DomU, but run it under Dom0, what is
the GSI and /proc/interrupts for the dmfe?
/proc/interrupts for dmfe in Dom0 (card is up and running, I disabled the
other):
cat /proc/interrupts | grep eth
11: 893 xen-pirq-xt-pic uhci_hcd:usb1, eth0
GSI: I'm not so sure what you mean but this must be GSI 11 (see above or dmesg
in attachment)
<blinks> Well, it looks like your motherboard has the IRQs below 16 to be
level.
That is odd.
Can you also attach the full serial output? (so we can see the Xen hypervisor
output
and the Linux Dom0 output).
This is what i get (see attached logs)
Thank you.
No, thank you for looking at this! :)
