This adds just enough performance counter support to measure the clock. We don't have linux kernel drivers for the clock driving the HW, and this was useful for determining that the V3D HW is running on a slow clock, not that the driver was slow. Signed-off-by:

Once we push the job, the scheduler could run it and free it. So, if we want to reference their fences, we need to grab them before then. I haven't seen this happen in many days of conformance test runtime, but let's still close the race. Signed-off-by:

drm_dp_cec_register_connector() is called when registering each DP connector in DRM, while sounds a good idea register CEC adapters as earlier as possible, it causes some driver initialization delay trying to do DPCD transactions in disconnected connectors. This change will cause no regressions as drm_dp_cec_set_edid() will still be called in further detection of connected connectors with a valid edid parameter. This change reduced the module load of i915 by average 0.5sec in a machine with just one DP port disconnected while reducing more than 3sec in a machine with 4 DP ports disconnected.

Since tcon->panel is a pointer returned by of_drm_find_panel() need to check if it is not NULL, hence a valid pointer. IS_ERR() instead checks return error values, not NULL pointers. Substitute "if (!IS_ERR(tcon->panel))" with "if (tcon->panel)". Signed-off-by:

With armada the last bigger driver that realistically needed these to convert from legacy kms to atomic is converted. These helpers have been broken more often than not the past 2 years, and as this little patch series shows, tricked a bunch of people into using the wrong helpers for their functions. Aside: I think a lot more drivers should be using the device-level drm_atomic_helper_shutdown/suspend/resume helpers and related functions. In almost all the cases they get things exactly right.

drm_plane_helper_disable is a non-atomic drivers only function, and will blow up (since no one passes the locking context it needs). Atomic drivers which want to quiescent their hw on unload should use drm_atomic_helper_shutdown() instead. Reviewed-by:

Atomic drivers which want to quiescent their hw on unload should use drm_atomic_helper_shutdown() instead. The sti cleanup code seems supremely confused: - In the load error path it calls drm_mode_config_cleanup before it stops various kms services like poll worker or fbdev emulation. That's going to oops. - The actual unload code doesn't even bother with the cleanup and just leaks. Try to fix this while at it. Reviewed-by:

It's the default. The exported version was kinda a transition state, before we made this the default.

For atomic driver this is the default, no need to reimplement it. We still need to keep the copypasta for not-atomic drivers though, since no one polished the legacy crtc helpers as much as the atomic ones. v2: amdgpu uses ->best_encoder internally, give it a local copy. It might be a good idea to merge the connector and encoder into one amdgpu_dm_sink structure, that might match DC internals better. At least for non-DPMST outputs. Kudos to Ville for spotting this. v3: Rebase onto a487411a ("drm/amd/display: Use DRM helper for best_encoder"). Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Let's make the infoframe pack functions usable with a const infoframe structure. This allows us to precompute the infoframe earlier, and still pack it later when we're no longer allowed to modify the structure. So now we end up with a _check()+_pack_only() or _pack() functions depending on whether you want to precompute the infoframes or not. The names aren't great but I was lazy and didn't want to change all the drivers. v2: Deal with exynos churn Actually export the new funcs v3: Fix various documentation fails (Hans) Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Hans Verkuil <hans.verkuil@cisco.com> Cc: linux-media@vger.kernel.org Signed-off-by:
