Hi, I have just upgraded my computer to Intel Core i5-4430 Quad Core @ 3.0 GHz (supports VT-d), ASRock B85M Pro4 micro-ATX LGA1150 motherboard (supports VT-d), 8 GB Kingston DDR3-1600 memory and Cooler Master Elite 311 ATX casing (all for SGD$501). I made my computer upgrade on Independence Day 4th July 2013. I have also flashed the UEFI BIOS of ASRock B85M Pro4 motherboard to version 1.50. In the UEFI B...

...ning merge (98bdc74b36) plus the DMA mapping merge (4e94d08734) reverted allows amdgpu + IOMMU + SME to once again work. I think that nobody is really working on amdgpu + SME, but it would be a shame if it was supported and then incidentally broken by a small change. I am using an ASRock B450 Pro4 with Ryzen 1600 and ASUS RX 480. I don't understand this code at all, but let me know what I can do to troubleshoot. Thanks, Alex.

Hello all, I just installed CentOS 7.8 on ASRock B460M Pro4 board. CPU is i5-10400. The display device is inside the CPU and the max resolution is 4096x2160 for HDMI. But when I connect my small screen (max full HD), the display resolution is only 800x600. >From seeing some info here, I installed EPEL for yum, and inxi. The "inxi -G" comman...

...and Debian Xen Team, I originally reported this bug in src:linux, as described above, but recent tests indicate a fix can be made in src:xen without any modifications to src:linux, so I suggest reassigning it from src:linux to src:xen. My explanation follows: On my system which is an ASRock B85M Pro4 (Haswell), with BIOS P2.50 12/11/2015, and with a jessie Xen Dom0 with a few patches to the old jessie Xen packages, I was able to successfully pass through the USB 3.0 controller, the sound card, and the Intel IGD to an unmodified bullseye HVM DomU without any of the problems I reported in the ori...

All the issues I had with the IOMMU, ACPI and ASPM are gone. I still have to pass the intel_iommu=igfx_off kernel parameter or I continue to see lots of DMAR errors for the first couple of seconds after booting and I can´t use the DVB tuners either. This last point...

This bug, at its core, is that currently there is no supported solution for VGA passthrough on Xen for stable version Jessie from Debian. After browsing Xen's repositories, I found out that Xen did not claim to support VGA passthrough with the upstream qemu-xen device model until Sep 25, 2015, the date the xl.cfg man page was updated to indicate support for VGA passthrough with upstream
