iris_drv_video.so not exsit #502

I'm using mesa20 and new "iris" driver for intel gen8+ graphic card(In my case is HD 530).

libva try to load iris_drv_video.so when mesa using iris driver, but it don't exsit . A workaround is create a symbol link to i965_drv_video.so.

$ vainfo
libva info: VA-API version 1.6.0
libva info: Trying to open /usr/lib/va/drivers/iris_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit
$ cd /usr/lib/va/drivers
$ ls
i965_drv_video.so
$ sudo ln -s i965_drv_video.so iris_drv_video.so
$ ls
i965_drv_video.so  iris_drv_video.so

The iris driver is part of the mesa project... so, this sounds like a mesa bug. Please file a report with them.

This project is for the i965 video driver. Mesa's i965 and iris drivers are opengl drivers.

Perhaps look at https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/283
