In function xf86VGAarbiterScrnInit when the "pEnt->bus.type" is BUS_PLATFORM, the "pScrn->vgaDev" won't be set, so the "pScrn->vgaDev" is equal to zero. The variable "rsrc_decodes" in function "xf86VGAarbiterAllowDRI" is not initialized. So it will occur error when "pScrn->vgaDev == 0", and "vga_count > 1". For this case, as "pScrn->vgaDev == 0", the function "pci_device_vgaarb_get_info" will only set the value of "vga_count", but won't set the value of "rsrc_decodes", so it will has two different return values for function "xf86VGAarbiterAllowDRI" in different platforms. One platform will return TRUE, as the "rsrc_decodes" 's default value is 0, but another platform will return FALSE, as the "rsrc_decodes" 's default value is "32767", this will cause disable direct rendering.

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.
For a comprehensive overview of X Server and X Window System, consult the
following article:
