Subject: [Intel-gfx] [PATCH 2/3] drm/i915/gem: sanity check object size in gem_create
Date: Thu, 14 Jan 2021 18:24:01 +0000	[thread overview]
Message-ID: <20210114182402.840247-2-matthew.auld@intel.com> (raw)
In-Reply-To: <20210114182402.840247-1-matthew.auld@intel.com>

Depending on the regions min_page_size we might need to adjust the
object size, ensure this matches our expectations.
