34  * Kernel-only values allowed in &pvr_gem_object->flags. The majority of options
35  * for this field are specified in the UAPI header "pvr_drm.h" with a

40  * To avoid potentially confusing gaps in the UAPI options, these kernel-only
43  * We use "reserved" to refer to bits defined here and not exposed in the UAPI.
47  *    :PVR_BO_CPU_CACHED: By default, all GEM objects are mapped write-combined on the CPU. Set this
61 /* Bits 2..0 are defined in the UAPI. */
67  * All firmware-mapped memory uses (mostly) the same flags. Specifically,
68  * firmware-mapped memory should be:
71  *  * Write-combined on the CPU.
79  * struct pvr_gem_object - powervr-specific wrapper for &struct drm_gem_object
91 	 * @flags: Options set at creation-time. Some of these options apply to
