drm/xe/uapi: Add block diagram of a device
In order to make proper use the uAPI, a prerequisite is to understand some key concepts about the discrete GPU devices which are supported by the Xe driver. For example, some structs defined in the uAPI are an abstraction of a hardware component with a specific role. This diagram helps to build a mental representation of a device how it is seen by the Xe driver. As written in the documentation, it does not intend to be a literal representation of an existing device. A lot more information could be added but the intention for the overview is to keep it simple, and go into detail as needed in other sections. v2: Add GT1 inside Tile0 (José Roberto de Souza) Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Acked-by: José Roberto de Souza <jose.souza@intel.com> Acked-by: Mateusz Naklicki <mateusz.naklicki@intel.com> Signed-off-by: Francois Dugast <francois.dugast@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
