Subject: [Intel-gfx] [PATCH 2/2] drm/i915/dmabuf: drop the flush on discrete
Date: Thu, 21 Oct 2021 13:53:32 +0100	[thread overview]
Message-ID: <20211021125332.2455288-2-matthew.auld@intel.com> (raw)
In-Reply-To: <20211021125332.2455288-1-matthew.auld@intel.com>

We were overzealous here; even though discrete is non-LLC, it should
still be always coherent.
