From f70000ef23527f6d928d1175c66c5fafa968814b Mon Sep 17 00:00:00 2001 From: Mary Guillemard Date: Mon, 9 Sep 2024 08:48:21 +0200 Subject: drm/panthor: Add DEV_QUERY_GROUP_PRIORITIES_INFO dev query Expose allowed group priorities with a new device query. This new uAPI will be used in Mesa to properly report what priorities a user can use for EGL_IMG_context_priority. Since this extends the uAPI and because userland needs a way to advertise priorities accordingly, this also bumps the driver minor version. v2: - Remove drm_panthor_group_allow_priority_flags definition - Document that allowed_mask is a bitmask of drm_panthor_group_priority v3: - Use BIT macro in panthor_query_group_priorities_info - Add r-b from Steven Price and Boris Brezillon Signed-off-by: Mary Guillemard Reviewed-by: Steven Price Reviewed-by: Boris Brezillon Signed-off-by: Steven Price Link: https://patchwork.freedesktop.org/patch/msgid/20240909064820.34982-4-mary.guillemard@collabora.com --- include/uapi/drm/panthor_drm.h | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) (limited to 'include/uapi') diff --git a/include/uapi/drm/panthor_drm.h b/include/uapi/drm/panthor_drm.h index 011a555e4674..87c9cb555dd1 100644 --- a/include/uapi/drm/panthor_drm.h +++ b/include/uapi/drm/panthor_drm.h @@ -263,6 +263,11 @@ enum drm_panthor_dev_query_type { /** @DRM_PANTHOR_DEV_QUERY_TIMESTAMP_INFO: Query timestamp information. */ DRM_PANTHOR_DEV_QUERY_TIMESTAMP_INFO, + + /** + * @DRM_PANTHOR_DEV_QUERY_GROUP_PRIORITIES_INFO: Query allowed group priorities information. + */ + DRM_PANTHOR_DEV_QUERY_GROUP_PRIORITIES_INFO, }; /** @@ -399,6 +404,23 @@ struct drm_panthor_timestamp_info { __u64 timestamp_offset; }; +/** + * struct drm_panthor_group_priorities_info - Group priorities information + * + * Structure grouping all queryable information relating to the allowed group priorities. + */ +struct drm_panthor_group_priorities_info { + /** + * @allowed_mask: Bitmask of the allowed group priorities. + * + * Each bit represents a variant of the enum drm_panthor_group_priority. + */ + __u8 allowed_mask; + + /** @pad: Padding fields, MBZ. */ + __u8 pad[3]; +}; + /** * struct drm_panthor_dev_query - Arguments passed to DRM_PANTHOR_IOCTL_DEV_QUERY */ -- cgit v1.2.3
