Subject: [Intel-gfx] [PATCH 2/3] drm/i915: prefer FORCE_WC for the blitter routines
Date: Mon, 18 Jan 2021 14:17:31 +0000	[thread overview]
Message-ID: <20210118141732.90173-2-matthew.auld@intel.com> (raw)
In-Reply-To: <20210118141732.90173-1-matthew.auld@intel.com>

From: CQ Tang <cq.tang@intel.com>

The pool is shared and so we might find that there is a pool object with
an existing mapping, but is mapped with different underlying type, which
will result in -EBUSY.
