Hi,
I recently got myself a brand new Intel GPU, I understand it's very recent hardware and I'm not expecting the most stable experience on Linux, still I wanted to get one. I updated my kernel and my system for the new GPU and everything seemed to work just fine, but mpv was failing to start, I tried in my terminal and this is the error I got :
| Code: | ● Video --vid=1 (vp9 1920x1080 25 fps) [default]
● Audio --aid=1 --alang=eng (opus 2ch 48000 Hz) [default]
Bus error
|
I disabled the hwdec=auto option and the video started playing. I also tried running vainfo and this is the error I got :
| Code: | Trying display: wayland
libva info: VA-API version 1.22.0
libva info: User environment variable requested driver 'iHD'
libva info: Trying to open /usr/lib64/va/drivers/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_22
Bus error
|
Anybody has an idea what am I doing wrong ?
Here are some info on my system, feel free to ask for more :

A brand new Intel graphics card in an AMD machine ... what could possibly go wrong ... 
But quite frankly: I have rarely seen such a clean (manual) kernel configuration. The only thing that gives me pause for thought is this:
| Code: | | [ 6.103353] xe 0000:07:00.0: [drm] Can't resize VRAM BAR - platform support is missing. Consider enabling 'Resizable BAR' support in your BIOS |
If that doesn't help, then you could still activate this (but I don't think that's the problem):
| Code: | # CONFIG_ACPI_FPDT is not set
# CONFIG_ACPI_PROCESSOR_AGGREGATOR is not set
# CONFIG_ACPI_HMAT is not set |
XE is still quite new ... and there are patches in every new kernel MINOR version ... 
Have you tried installing the latest version of “mesa”? If so, then you will probably have to wait for newer kernel versions.
BTW:
You definitely don't need this (only Intel CPUs have/need this):
| Code: | CONFIG_INTEL_MEI=y
CONFIG_INTEL_IOMMU=y |
And I just don't think so:
This does not work:
| Code: | | CONFIG_GENTOO_KERNEL_SELF_PROTECTION=y |
The reason why it does not work you could read here: https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Kernel_Hardening_with_KSPP
