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 <[email protected]> # Conflicts: # drivers/gpu/drm/panthor/panthor_drv.c From: Maarten Lankhorst <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

The drm/Panthor driver implements the DRM client usage stats specification as

Possible `drm-engine-` key names are: `panthor`.
36+
`drm-curfreq-` values convey the current operating frequency for that engine.
37+
38+
Users must bear in mind that engine and cycle sampling are disabled by default,
39+
because of power saving concerns. `fdinfo` users and benchmark applications which
40+
query the fdinfo file must make sure to toggle the job profiling status of the
41+
driver by writing into the appropriate sysfs node::
42+
43+
echo <N> > /sys/bus/platform/drivers/panthor/[a-f0-9]*.gpu/profiling
44+
45+
Where `N` is a bit mask where cycle and timestamp sampling are respectively
46+
enabled by the first and second bits.
