Subject: [PATCH v3 1/5] gem/vram: pin to vram in vmap
Date: Thu, 27 Jun 2019 14:23:44 +0200 [thread overview]
Message-ID: <20190627122348.5833-2-kraxel@redhat.com> (raw)
In-Reply-To: <20190627122348.5833-1-kraxel@redhat.com>
drm clients like the generic framebuffer emulation keep a permanent
vmap active, which in turn has a permanent pin. This pin needs to
be in vram, otherwise we can't display the framebuffer.
