#define DRM_PVR_BO_BYPASS_DEVICE_CACHE   _BITULL(0)

DOC: PowerVR IOCTL CREATE_BO interface DOC: Flags for CREATE_BO

We use "device" to refer to the GPU here because of the ambiguity between CPU and GPU in some fonts.

Device mapping options :DRM_PVR_BO_BYPASS_DEVICE_CACHE: Specify that device accesses to this memory will bypass the cache. This is used for buffers that will either be regularly updated by the CPU (eg free lists) or will be accessed only once and therefore isn't worth caching (eg partial render buffers). By default, the device flushes its memory caches after every job, so this is not normally required for coherency. :DRM_PVR_BO_PM_FW_PROTECT: Specify that only the Parameter Manager (PM) and/or firmware processor should be allowed to access this memory when mapped to the device. It is not valid to specify this flag with DRM_PVR_BO_ALLOW_CPU_USERSPACE_ACCESS.

CPU mapping options :DRM_PVR_BO_ALLOW_CPU_USERSPACE_ACCESS: Allow userspace to map and access the contents of this memory. It is not valid to specify this flag with DRM_PVR_BO_PM_FW_PROTECT.

DOC: PowerVR IOCTL interface PVR_IOCTL() - Build a PowerVR IOCTL number @_ioctl: An incrementing id for this IOCTL. Added to DRM_COMMAND_BASE. @_mode: Must be one of DRM_IOR, DRM_IOW or DRM_IOWR. @_data: The type of the args struct passed by this IOCTL.

The struct referred to by @_data must have a drm_pvr_ioctl_ prefix and an _args suffix. They are therefore omitted from @_data.

This should only be used to build the constants described below; it should never be used to call an IOCTL directly.

Return: An IOCTL number to be passed to ioctl() from userspace.

enum drm_pvr_static_data_area_usage - Array index for static data area info returned by DRM_PVR_DEV_QUERY_STATIC_DATA_AREAS_GET.

For compatibility reasons all indices will be present in the returned array, however some areas may not be present. These are indicated where &struct drm_pvr_static_data_area.size is set to zero.

Enumerator
DRM_PVR_STATIC_DATA_AREA_EOT	@DRM_PVR_STATIC_DATA_AREA_EOT: End of Tile PDS program code segment. The End of Tile PDS task runs at completion of a tile during a fragment job, and is responsible for emitting the tile to the Pixel Back End.
DRM_PVR_STATIC_DATA_AREA_FENCE	@DRM_PVR_STATIC_DATA_AREA_FENCE: MCU fence area, used during cache flush and invalidation. This must point to valid physical memory but the contents otherwise are not used.
DRM_PVR_STATIC_DATA_AREA_VDM_SYNC	@DRM_PVR_STATIC_DATA_AREA_VDM_SYNC: VDM sync program. The VDM sync program is used to synchronise multiple areas of the GPU hardware.
DRM_PVR_STATIC_DATA_AREA_YUV_CSC	@DRM_PVR_STATIC_DATA_AREA_YUV_CSC: YUV coefficients. Area contains up to 16 slots with stride of 64 bytes. Each is a 3x4 matrix of u16 fixed point numbers, with 1 sign bit, 2 integer bits and 13 fractional bits. The slots are : 0 = VK_SAMPLER_YCBCR_MODEL_CONVERSION_RGB_IDENTITY_KHR 1 = VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_IDENTITY_KHR (full range) 2 = VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_IDENTITY_KHR (conformant range) 3 = VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_709_KHR (full range) 4 = VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_709_KHR (conformant range) 5 = VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_601_KHR (full range) 6 = VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_601_KHR (conformant range) 7 = VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_2020_KHR (full range) 8 = VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_2020_KHR (conformant range) 9 = VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_601_KHR (conformant range, 10 bit) 10 = VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_709_KHR (conformant range, 10 bit) 11 = VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_2020_KHR (conformant range, 10 bit) 14 = Identity (biased) 15 = Identity
