Truncate the name nvidia(nvid), amdgpu(amdg), libva error: vaGetDriverNames() failed with unknown libva error #750

Closed denji closed 1 year ago

denji commented 1 year ago

If VAAPI does not support multiple dGPUs/iGPUs to select, is there a possibility to specify via an environment variable the path drm device /dev/dri/renderD129 to the iGPU that has second priority?

libva does not select the device by itself, it get the device from application or other components. lets use drm as the example: application call fd =open("/dev/dri/renderXXX",...) , then call vaGetDisplayDRM(fd), then call vaInitialize() so, all is controlled in upper layer.

maybe you want a priority list in libva-utils?

@XinfengZhang It seems to be causing the driver to crash https://github.com/intel/libva-utils/blob/2.19.0/common/va_display_drm.c#L49-L51
