After libva 2.22 vainfo doesn't launch (libEGL_mesa.so.0: undefined symbol: wl_drm_interface)

Description:

After libva 2.22 vainfo exits with error (libEGL_mesa.so.0: undefined symbol: wl_drm_interface)

If downgrading libva, it launches. Maybe mesa needs to sync with libva.

$ vainfo 
Trying display: wayland
error: failed to resolve wl_drm_interface(): /usr/lib/libEGL_mesa.so.0: undefined symbol: wl_drm_interface
libva error: /usr/lib/dri/i965_drv_video.so init failed
vaInitialize failed with error code -1 (unknown libva error),exit

Additional info:

• libva 2.22.0-1
• libva-utils 2.22.0-1
• mesa 1:24.1.4-2

As far as I can tell from that, the issue is not with libva itself.
/usr/lib/dri/i965_drv_video.so belongs to libva-intel-driver package.

What is interesting here is error: failed to resolve wl_drm_interface(): /usr/lib/libEGL_mesa.so.0: undefined symbol: wl_drm_interface

from the commits of libva:

https://github.com/intel/libva/commit/1b7d71f68b6ebc7f7c3b80e3eb6b3d888b0463e1

wl_drm is a legacy protocol, and wlroots is getting rid of it [1].
Use the newer and standard linux-dmabuf protocol if available to
get the DRM device.

as /usr/lib/libEGL_mesa.so.0 belongs to mesa, and it's not happy, maybe mesa should be compiled against new libva?

Idk, I can't reproduce the issue. I don't have a i965 iGPU.

Are you sure you don't want intel-media-driver instead of libva-intel-driver?

doesn't open at all, even with downgraded libva.

$ vainfo 
Trying display: wayland
libva error: /usr/lib/dri/iHD_drv_video.so init failed
vaInitialize failed with error code -1 (unknown libva error),exit

Hmm, maybe it's indeed not compatble. iHD driver is for Broadwell+. What CPU/iGPU do you have?

Although, it's libva depends on mesa, not vice versa. So I doubt it being a root of the problem. But you could try to rebuild it yourself, if you think it should help.

Btw, does the actual video acceleration works? Or it's only the vainfo command problem?

Judging by intel_gpu_top seems, it has no accel now. Reverting libva helps.

Will try to build mesa.

I found the root cause: https://github.com/intel/intel-vaapi-driver/pull/566

Fetching wl_drm_interface from libEGL used to work but doesn't anymore: it's now a private symbol (wayland-scanner private-code).

Will try to build mesa.

It won't help. Instead, try to rebuild libva-intel-driver with the patch above applied.

Recompiled libva-intel-driver with the patch, it helped.

Ok, I guess you could close this issue then and open a new issue in libva-intel-driver with a backport request, if you want.
