Hey yall,
I’m trying to switch the gpu I use for my vfio/looking glass setup I updated my grub to have the new pci-stub.ids and black listed the drivers but im getting iommu ivhd0: AMD-Vi: Event logged [IOTLB_INV_TIMEOUT device=0000:05:00.0 address=0x100314eb0]
I had everything working for the past year with my gtx1080 being passed through and my gtx1060 as the host device. Any suggestions or places to start? New gpu is intel arc b580. Mobo x570 phantom gaming 4 and cpu is 3900x
I also see [ 137.988206] vfio-pci 0000:05:00.0: No more image in the PCI ROM
in my dmesg.
Grub line
GRUB_CMDLINE_LINUX="rd.driver.blacklist=nouveau,xe modprobe.blacklist=nouveau,xe rhgb quiet amd_iommu=on iommu=pt rd.driver.pre=vfio-pci pci-stub.ids=8086:e20b,8086:e2f7 rd.driver.blacklist=nouveau,xe modprobe.blacklist=nouveau,xe amd_pstate.shared_mem=1 amd_pstate=enable"
Oddly it looks like the kernel module was ignored so I don’t think my grub options are the issue? lspci -nnk output below

I know my setup still works as I was able to swap my old 1080 back in and set its stubs back in grub and everything works as it should with looking glass and the whole system. Any suggestions or help would be greatly appreciated.
