Hi
Firstly, apologies if this has been raised before. (It was suggested I place this here)
I have a HP xw4600 workstation PC and am trying to get iommu working.
The bios has VT-x and VT-d enabled as shown in the photos.
In PCI setting it shows 1 of the cards coming up as disabled but it is showing in the logs on unraid.
Has anyone any idea, I have attached logs from my system.
My BIOS is the latest: 01.34 Rev A.
ARK says my chip supports both vt-x and vt-d: http://ark.intel.com/products/33922/Intel-Core2-Quad-Processor-Q9300-6M-Cache-2_50-GHz-1333-MHz-FSB
The 2 graphics cards are : AMD/ATI R7 260X and NVIDIA GFX 1800. I also have an old PCI MGI Matrox card fro unRAID to use (shows the CLI).
I have also tried passing this in the sysconfig.cfg file
vfio_iommu_type1.allow_unsafe_interrupts=1 initrd=/bzroot
On bootup I get failed
Apr 7 09:12:18 Tower kernel: WARNING: CPU: 0 PID: 0 at drivers/iommu/dmar.c:844 warn_invalid_dmar+0x70/0x7d Apr 7 09:12:18 Tower kernel: Your BIOS is broken; DMAR reported at address fed90000 returns all ones!
If anyone can help I'd appreciate it. If anymore info is needed please let me know.
