glamor calls DRM_IOCTL_GEM_FLINK to get a name for a buffer object. It only works for driver that support GEM, such as intel i915 driver. But for pvr driver who doesn't has GEM, we can't do it this way. According to Chris's comments, we check the has_gem as the following method: Here we just try to flink handle 0. If that fails with ENODEV or ENOTTY instead of ENOENT (or EINVAL on older kernels), set has_gem=0. Signed-off-by: Li Peng <peng.li@intel.com> Reviewed-by: Zhigang Gong <zhigang.gong@linux.intel.com>
X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
