Subject: [Intel-gfx] [PATCH v2 01/15] drm/i915: add io_size plumbing
Date: Thu, 10 Feb 2022 12:12:59 +0000 [thread overview]
Message-ID: <20220210121313.701004-2-matthew.auld@intel.com> (raw)
In-Reply-To: <20220210121313.701004-1-matthew.auld@intel.com>
With small LMEM-BAR we need to be able to differentiate between the
total size of LMEM, and how much of it is CPU mappable. The end goal is
to be able to utilize the entire range, even if part of is it not CPU
accessible.
v2: also update intelfb_create
