2021-11-17drm/i915: Clarify probing order in intel_dp_aux_init_backlight_funcs()Lyude Paul1-5/+11
Hooray! We've managed to hit enough bugs upstream that I've been able to come up with a pretty solid explanation for how backlight controls are actually supposed to be detected and used these days. As well, having the rest of the PWM bits in VESA's backlight interface implemented seems to have fixed all of the problematic brightness controls laptop panels that we've hit so far. So, let's actually document this instead of just calling the laptop panels liars. As well, I would like to formally apologize to all of the laptop panels I called liars. I'm sorry laptop panels, hopefully you can all forgive me and we can move past this~ Signed-off-by: Lyude Paul <lyude@redhat.com> Acked-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211105183342.130810-6-lyude@redhat.com
2021-11-17drm/dp, drm/i915: Add support for VESA backlights using PWM for brightness controlLyude Paul2-31/+85
Now that we've added support to i915 for controlling panel backlights that need PWM to be enabled/disabled, let's finalize this and add support for controlling brightness levels via PWM as well. This should hopefully put us towards the path of supporting _ALL_ backlights via VESA's DPCD interface which would allow us to finally start trusting the DPCD again. Note however that we still don't enable using this by default on i915 when it's not needed, primarily because I haven't yet had a chance to confirm if it's safe to do this on the one machine in Intel's CI that had an issue with this: samus-fi-bdw. I have done basic testing of this on other machines though, by manually patching i915 to force it into PWM-only mode on some of my laptops. v2: * Correct documentation (thanks Doug!) * Get rid of backlight caps Signed-off-by: Lyude Paul <lyude@redhat.com> Reviewed-by: Doug Anderson <dianders@chromium.org> Cc: Rajeev Nandan <rajeevny@codeaurora.org> Cc: Satadru Pramanik <satadru@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211105183342.130810-5-lyude@redhat.com
2021-11-17drm/dp: Don't read back backlight mode in drm_edp_backlight_enable()Lyude Paul1-28/+12
As it turns out, apparently some machines will actually leave additional backlight functionality like dynamic backlight control on before the OS loads. Currently we don't take care to disable unsupported features when writing back the backlight mode, which can lead to some rather strange looking behavior when adjusting the backlight. So, let's fix this by just not reading back the current backlight mode on initial enable. I don't think there should really be any downsides to this, and this will ensure we don't leave any unsupported functionality enabled. This should fix at least one (but not all) of the issues seen with DPCD backlight support on fi-bdw-samus v5: * Just avoid reading back DPCD register - Doug Anderson Signed-off-by: Lyude Paul <lyude@redhat.com> Fixes: 867cf9cd73c3 ("drm/dp: Extract i915's eDP backlight code into DRM helpers") Reviewed-by: Douglas Anderson <dianders@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20211105183342.130810-4-lyude@redhat.com

2021-11-17drm/i915: Add support for panels with VESA backlights with PWM enable/disableLyude Paul1-6/+21
This simply adds proper support for panel backlights that can be controlled via VESA's backlight control protocol, but which also require that we enable and disable the backlight via PWM instead of via the DPCD interface. We also enable this by default, in order to fix some people's backlights that were broken by not having this enabled. For reference, backlights that require this and use VESA's backlight interface tend to be laptops with hybrid GPUs, but this very well may change in the future. v4: * Make sure that we call intel_backlight_level_to_pwm() in intel_dp_aux_vesa_enable_backlight() - vsyrjala Signed-off-by: Lyude Paul <lyude@redhat.com> Link: https://gitlab.freedesktop.org/drm/intel/-/issues/3680 Fixes: fe7d52bccab6 ("drm/i915/dp: Don't use DPCD backlights that need PWM enable/disable") Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: <stable@vger.kernel.org> # v5.12+ Link: https://patchwork.freedesktop.org/patch/msgid/20211105183342.130810-2-lyude@redhat.com

2021-11-17drm/amd/display: retain/release stream pointer in link enc tableSung Joon Kim1-0/+2
[why] At every reference to stream pointer, we need to increment/decrement the kref_count. Not doing so will result in invalid stream pointer still alive after hibernate cycle. [how] Call stream retain/release whenever the link encoder assignment is set to true/false since it indicates if we want to reference the stream pointer or not.

2021-11-17drm/amd/display: fix stale info in link encoder assignmentRoy Chan1-22/+14
[Why] The link encoder assignment leaves the old stream data when it was unassigned. When the clear encoder assignment is called, it based on the old stale data to access the de-allocated stream. [How] There should be no need to explicitly clean up the link encoder assignment if the unassign loop does the work properly, the loop should base on the current state to clean up the assignment. Also, the unassignment should better clean up the values in the assignement slots as well.

2021-11-17drm/amd/display: Fix detection of aligned DMUB firmware meta infoNicholas Kazlauskas1-16/+27
[Why] A built firmware binary may be aligned to 16-bytes with padding at the end as necessary. In the case that padding was applied the meta info will not be detected correctly and we won't be able to allocate the appropriate firmware and tracebuffer sizes. [How] To maintain compatibility with already released firmware where this occurs we need to try every meta offset from 0..15 inclusive. Extract out the meta info checker into a helper function that's called for each of these offsets and exit early when we've found it.
