Troubleshooting Intel B580 GPU for encoding

[chanthemad]

So I bought an Intel Arc B580 (Battlemage) GPU in order to do some encoding for Jellyfin. I'm running Ubuntu 24.04 LTS 6.14 HWE Kernel.  

However, I can't get it to work. I followed https://jellyfin.org/docs/general/post-i...nux-setups

I did check version of the intel-opencl-icd. It is up to date. 

Then I checked the supported QSV/VA-API codecs. How it supposed to look like is this: 

sudo /usr/lib/jellyfin-ffmpeg/vainfo --display drm --device /dev/dri/renderD128

libva info: VA-API version 1.17.0
libva info: Trying to open /usr/lib/jellyfin-ffmpeg/lib/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_17
libva info: va_openDriver() returns 0
Trying display: drm
vainfo: VA-API version: 1.17 (libva 2.17.0)
vainfo: Driver version: Intel iHD driver for Intel® Gen Graphics - 23.1.2 (xxxxxxx)
vainfo: Supported profile and entrypoints

Mines looks like this: 

sudo /usr/lib/jellyfin-ffmpeg/vainfo --display drm --device /dev/dri/renderD128

Trying display: drm
libva info: VA-API version 1.22.0
libva info: Trying to open /usr/lib/jellyfin-ffmpeg/lib/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_22

Bus error

How would I fix this bus error? 

Also I checked the Open CL runtime status. Supposed to look like this... 

sudo /usr/lib/jellyfin-ffmpeg/ffmpeg -v verbose -init_hw_device vaapi=vadev/dri/renderD128 -init_hw_device opencl@va

[AVHWDeviceContext @ 0x55cc8ac21a80] 0.0: Intel® OpenCL HD Graphics / Intel® Iris® Xe Graphics [0x9a49]

Mines looks like this: 

sudo /usr/lib/jellyfin-ffmpeg/ffmpeg -v verbose -init_hw_device vaapi=vadev/dri/renderD128 -init_hw_device opencl@va

Bus error

Another bus error. So my question is, how do we fix this problem? 

When I try to detect the GPU with lspci -nn | grep -Ei "3d|display|vga"

11:00.0 VGA compatible controller [0300]: Intel Corporation Device..  [8086:e20b]

It is getting picked up. 

Also on the encoding dashboard, which codecs should I check? 

Thanks in advance.

Well I fixed it, I just checked to enable Re-sizable BAR or ReBAR in the BIOS.

I posted this on this forum because I thought I had enabled it in the BIOS, but upon further review, it wasn't enabled. 

Credit this post for pointing me in the right direction.  https://github.com/jellyfin/jellyfin/issues/13944

Curious, what encoding settings should I use now?
