Subject: [Intel-gfx] [PATCH 3/3] drm/i915/gtt: ignore min_page_size for paging structures
Date: Wed, 23 Jun 2021 12:26:37 +0100 [thread overview]
Message-ID: <20210623112637.266855-3-matthew.auld@intel.com> (raw)
In-Reply-To: <20210623112637.266855-1-matthew.auld@intel.com>
The min_page_size is only needed for pages inserted into the GTT, and
for our paging structures we only need at most 4K bytes, so simply
ignore the min_page_size restrictions here, otherwise we might see some
severe overallocation on some devices.
