Also add DRM_XE_OA_CAPS_SYNCS bit in OA capabilities for userspace. v2: Fix and document DRM_XE_SYNC_TYPE_USER_FENCE for OA (Matt B) Add DRM_XE_OA_CAPS_SYNCS bit to OA capabilities (Jose) Acked-by: José Roberto de Souza Reviewed-by: Jonathan Cavitt Signed-off-by: Ashutosh Dixit Link: https://patchwork.freedesktop.org/patch/msgid/20241022200352.1192560-3-ashutosh.dixit@intel.com Stable-dep-of: f0ed39830e60 ("xe/oa: Fix query mode of operation for OAR/OAC") Signed-off-by: Sasha Levin --- include/uapi/drm/xe_drm.h | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) (limited to 'include/uapi') diff --git a/include/uapi/drm/xe_drm.h b/include/uapi/drm/xe_drm.h index c4182e95a619..4a8a4a63e99c 100644 --- a/include/uapi/drm/xe_drm.h +++ b/include/uapi/drm/xe_drm.h @@ -1485,6 +1485,7 @@ struct drm_xe_oa_unit { /** @capabilities: OA capabilities bit-mask */ __u64 capabilities; #define DRM_XE_OA_CAPS_BASE (1 << 0) +#define DRM_XE_OA_CAPS_SYNCS (1 << 1) /** @oa_timestamp_freq: OA timestamp freq */ __u64 oa_timestamp_freq; @@ -1634,6 +1635,22 @@ enum drm_xe_oa_property_id { * to be disabled for the stream exec queue. */ DRM_XE_OA_PROPERTY_NO_PREEMPT, + + /** + * @DRM_XE_OA_PROPERTY_NUM_SYNCS: Number of syncs in the sync array + * specified in @DRM_XE_OA_PROPERTY_SYNCS + */ + DRM_XE_OA_PROPERTY_NUM_SYNCS, + + /** + * @DRM_XE_OA_PROPERTY_SYNCS: Pointer to struct @drm_xe_sync array + * with array size specified via @DRM_XE_OA_PROPERTY_NUM_SYNCS.
