Hi VFIO,
I'm hoping to get some help with an error i'm receiving when trying to
passthrough a creative soundblaster pcie card. the vm crashes with the
following message in the vm log file
2017-01-17T19:51:09.573169Z qemu-system-x86_64: VFIO_MAP_DMA: -14
2017-01-17T19:51:09.573195Z qemu-system-x86_64: vfio_dma_map(0x5613ff681480,
0x98000000, 0x4000, 0x7f22a4c22000) = -14 (Bad address)
Ok, first off. HARDWARE:
I am running a dell precision t5500 with dual hexa-core processors running
NUMA. the MB has 5 pcie slots, and according to the service manual, slots 1,3,5
are pcix16 wired at 8x. slot 2 has my "host" graphics Nvidia Quadro 4000, and
slot 4 has my guest gpu Radein rx480, each one hooked up to a separate monitor.
(the reason i mention the slots is further down)
OS
Linux fedser.localdomain 4.8.6-300.fc25.x86_64 #1 SMP Tue Nov 1 12:36:38 UTC
2016 x86_64 x86_64 x86_64 GNU/Linux
IOMMU_GROUP
IOMMU Group 17 22:00.0 PCI bridge [0604]: Creative Labs [SB X-Fi Xtreme Audio]
CA0110-IBG PCIe to PCI Bridge [1102:7006]
IOMMU Group 17 23:00.0 Audio device [0403]: Creative Labs CA0110 [Sound Blaster
X-Fi Xtreme Audio] [1102:0009]
No matter whether i put it in slot 1,3 or 5. The grouping is always the same,
the pcie bridge and the sound card. I am only stubbing the sound card itself
and not the bridge.
So i don't think grouping is an issue.

BUT, here is where i'm getting stuck. The other day, i decided to try something
different. I moved the Nvidia card from slot2 to slot3 and put the soundblaster
into slot2. And lo and behold, it worked. I already have a win7 vm with ovmf
and the radeon up and working, and i was able to add the soundblaster to the vm
and windows recognized it, i was able to install the software and it tested out
perfectly. However, apparently my bios is limited by what slots it looks at for
video cards, so i actually lost my display thru nvidia. It wouldn't show up at
all. in my bios i found that i have 2 choices for video either it looks for
cards in one of two orders; pcix,pcieslot2,pcieslot4,pci or
pci,pcieslot4,pcieslot2,pcix. So it won't even look in slot3 for video unless i
force it by removing all other cards. And actually, no matter the setting, it
would actually default to the AMD monitor even though i have the driver stubbed.
I would really like to get this card into my win7 vm, and i've been researching
for about a week and haven't gotten any further than getting it to work but
losing my display in the process.
Any help or ideas would be appreciated, and please let me know any other info
that is needed.
Thanks,
Jeff
