[Intel-gfx] [PATCH] drm/i915/gt: Taint the reset mutex with the shrinker

[Intel-gfx] [PATCH] drm/i915/gt: Taint the reset mutex with the shrinker

[Chris Wilson]

Declare that, under extreme circumstances, the shrinker may need to wait
upon a request, in which case reset must not itself deadlock in order to
ensure forward progress of the driver. That is since the shrinker may
depend upon a reset, any reset cannot touch the shrinker.

Re: [Intel-gfx] [PATCH] drm/i915/gt: Taint the reset mutex with the shrinker

[Mika Kuoppala]

Chris Wilson <chris@chris-wilson.co.uk> writes:

> Declare that, under extreme circumstances, the shrinker may need to wait
> upon a request, in which case reset must not itself deadlock in order to
> ensure forward progress of the driver. That is since the shrinker may
> depend upon a reset, any reset cannot touch the shrinker.
