As a textured_drm pixmap has a drm bo attached to it, and it's the DDX layer to set it stride value. In some case, the stride value is not equal to PixmapBytePad(w, depth) which is used within glamor. Then if it is the case, we have two choice, one is to set the GL_PACK_ROW_LENGTH/GL_UNPACK_ROW_LENGTH when we need to download or upload the pixmap. The other option is to change the pixmap's devKind to match the one glamor is using when downloading the pixmap, and restore it to the drm stride after uploading the pixmap. We choose the 2nd option, as GLES doesn't support the first method. Signed-off-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.
