Subject: [PATCH 7/7] drm/ttm: do not keep GPU dependent addresses
Date: Mon, 17 Feb 2020 11:18:41 +0100 [thread overview]
Message-ID: <20200217101841.7437-8-nirmoy.das@amd.com> (raw)
In-Reply-To: <20200217101841.7437-1-nirmoy.das@amd.com>
GPU address handling is device specific and should be handle by its device
driver.
