The intel-media-driver is currently broken on DG1 because it uses EXEC_CAPTURE with recovarable contexts. Relax the check to allow that.
I've also submitted a fix for the intel-media-driver: https://github.com/intel/media-driver/pull/1920

The IS_DGFX check was there because the error capture is expected to be broken on anything with VRAM.
If we have already submitted an userspace fix to remove that flag, that would be the right way to go.
So reverting this for now.

Oh! We need to add a comment there, though, because in the future I expect someone else might decide to send the same patch.

I don't care. It's a regression that prevents current userspace from working.
If we have already submitted an userspace fix to remove that flag, that would be the right way to go.
There has a been an open pull request for that for who knows how long without any action.
So reverting this for now.
*You* make sure a userspace fix actually gets released then.

(Spoiler: The userspace fix seems to be accepted and released.)
It's always bit murky when a platform stays under force_probe for extended period of time, but it was never considered to be finalized from memory management perspective at the time of adding this check.
Now you are just unblocking codepaths that are simply not expected to work, and as it's in rather fragile part of the device resets so that's bit of a no-go.
So if you really would prefer to drop this check for DG1, options would be to implement the page copying for VRAM (probably bit much work) or alternatively we could just ignore the flag for DG1 specifically.
If we have already submitted an userspace fix to remove that flag, that would be the right way to go.

Per GIT history[1] it should already be part of media-driver release 25.2.3 which was released last week. Or am I looking at the wrong fix?
