…g/drm/misc/kernel into drm-next drm-misc-next for v6.13: UAPI Changes: - Add drm fdinfo support to panthor, and add sysfs knob to toggle. Cross-subsystem Changes: - Convert fbdev drivers to use backlight power constants. - Some small dma-fence fixes. - Some kernel-doc fixes. Core Changes: - Small drm client fixes. - Document requirements that you need to file a bug before marking a test as flaky. - Remove swapped and pinned bo's from TTM lru list. Driver Changes: - Assorted small fixes to panel/elida-kd35t133, nouveau, vc4, imx. - Fix some bridges to drop cached edids on power off. - Add Jenson BL-JT60050-01A, Samsung s6e3ha8 & AMS639RQ08 panels. - Make 180° rotation work on ilitek-ili9881c, even for already-rotated panels. - Signed-off-by: Dave Airlie <airlied@redhat.com> # Conflicts: # drivers/gpu/drm/panthor/panthor_drv.c From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/8dc111ca-d20c-4e0d-856e-c12d208cbf2a@linux.intel.com

+Panthor DRM client usage stats implementation
+==============================================
+
+The drm/Panthor driver implements the DRM client usage stats specification as
+documented in :ref:`drm-client-usage-stats`.
+
+Example of the output showing the implemented key value pairs and entirety of
+the currently possible format options:
+

+     pos:    0
+     flags:  02400002

+     drm-resident-memory:    16480 KiB
+     drm-purgeable-memory:   0
+
+Possible `drm-engine-` key names are: `panthor`.
+`drm-curfreq-` values convey the current operating frequency for that engine.
+
+Users must bear in mind that engine and cycle sampling are disabled by default,
+because of power saving concerns. `fdinfo` users and benchmark applications which
+query the fdinfo file must make sure to toggle the job profiling status of the
+driver by writing into the appropriate sysfs node::
+
+    echo <N> > /sys/bus/platform/drivers/panthor/[a-f0-9]*.gpu/profiling
+
+Where `N` is a bit mask where cycle and timestamp sampling are respectively
+enabled by the first and second bits.
