Detailed Description

struct drm_xe_gt - describe an individual GT.

To be used with drm_xe_query_gt_list, which will return a list with all the existing GT individual descriptions. Graphics Technology (GT) is a subset of a GPU/tile that is responsible for implementing graphics and/or media operations.

The index in @type can be:

DRM_XE_QUERY_GT_TYPE_MAIN
DRM_XE_QUERY_GT_TYPE_MEDIA

Member Data Documentation

◆ far_mem_regions

__u64 drm_xe_gt::far_mem_regions

@far_mem_regions: Bit mask of instances from drm_xe_query_mem_regions that are far from the engines of this GT. In general, they have extra indirections when compared to the @near_mem_regions. For a discrete device this could mean system memory and memory living in a different tile. Each index in this mask refers directly to the struct drm_xe_query_mem_regions' instance, no assumptions should be made about order. The type of each region is described by struct drm_xe_query_mem_regions' mem_class.

◆ gt_id

__u16 drm_xe_gt::gt_id

@gt_id: Unique ID of this GT within the PCI Device

◆ ip_ver_major

__u16 drm_xe_gt::ip_ver_major

@ip_ver_major: Graphics/media IP major version on GMD_ID platforms

◆ ip_ver_minor

__u16 drm_xe_gt::ip_ver_minor

@ip_ver_minor: Graphics/media IP minor version on GMD_ID platforms

◆ ip_ver_rev

__u16 drm_xe_gt::ip_ver_rev

@ip_ver_rev: Graphics/media IP revision version on GMD_ID platforms

◆ near_mem_regions

__u64 drm_xe_gt::near_mem_regions

@near_mem_regions: Bit mask of instances from drm_xe_query_mem_regions that are nearest to the current engines of this GT. Each index in this mask refers directly to the struct drm_xe_query_mem_regions' instance, no assumptions should be made about order. The type of each region is described by struct drm_xe_query_mem_regions' mem_class.

◆ pad

__u16 drm_xe_gt::pad[3]

@pad: MBZ

◆ pad2

__u16 drm_xe_gt::pad2

@pad2: MBZ

◆ reference_clock

__u32 drm_xe_gt::reference_clock

@reference_clock: A clock frequency for timestamp

◆ reserved

__u64 drm_xe_gt::reserved[7]

@reserved: Reserved

◆ tile_id

__u16 drm_xe_gt::tile_id

@tile_id: Tile ID where this GT lives (Information only)

◆ type

__u16 drm_xe_gt::type

@type: GT type: Main or Media
