Subject: [PATCH 08/19] drm/i915: Return error value when bo not in LMEM for discrete
Date: Mon, 12 Apr 2021 10:05:15 +0100 [thread overview]
Message-ID: <20210412090526.30547-9-matthew.auld@intel.com> (raw)
In-Reply-To: <20210412090526.30547-1-matthew.auld@intel.com>
From: Mohammed Khajapasha <mohammed.khajapasha@intel.com>
Return EREMOTE value when frame buffer object is not backed by LMEM
for discrete. If Local memory is supported by hardware the framebuffer
backing gem objects should be from local memory.
