Subject: [PATCH 05/19] drm/i915/stolen: enforce the min_page_size contract
Date: Mon, 12 Apr 2021 10:05:12 +0100	[thread overview]
Message-ID: <20210412090526.30547-6-matthew.auld@intel.com> (raw)
In-Reply-To: <20210412090526.30547-1-matthew.auld@intel.com>

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

Since stolen can now be device local-memory underneath, we should try to
enforce any min_page_size restrictions when allocating pages.
