[PATCH v3 0/8] Fixes and updates when using AUX backlight using Luminance

[Suraj Kandpal]

This series aims to fix/update some code with respect to AUX backlight
via luminance values for both VESA and INTEL HDR codepaths.
The below are the major changes made in this series.
- Do not allow 0 brightness  by default which makes the screen go blank
leaving user with no way to see the screen and increase brightness.
- Take into account luminance_set variable when we decide which funcs
need to be enabled
- Update debug logs to make them more concise and help debug which
code path was taken

[PATCH v3 1/8] drm/i915/backlight: Use default/max brightness for VESA AUX backlight init

[Suraj Kandpal]

If the brightness fetched from VBT/previous state is 0 on backlight
initialization, then set the brightness to a default/max value.
Whenever the minimum brightness is reported as 0 there are chances
we end up with blank screen. This confuses the user into thinking
the display is acting weird. This occurs in eDP 1.5 when
we are using PANEL_LUMINANCE_OVERRIDE mode to mainpulate brightness
via luminance values.

How does this help when .enabled is still based on level != 0 above?

Well we keep the backlight.enabled as false if we read a 0 back from the DPCD or the current level state is 0.
This is to maintain the policy that if during setup we get 0 as backlight value eDP backlight is currently disabled
(which means __intel_backlight_enable needs be called). We then change the current level to max so that when
backlight enable is called after setup from intel_backlight_update, we enable backlight with max level so that we
do not end up with a blank screen. This is also where we set backlight.enabled = true.
This is  to tackle different eDP behavior where, some preserve the last brightness value programmed in them (in that case
users want the same brightness to continue) while others don't and just 0 it out instead of having some default value (in that
case we keep backlight.enabled = false later to be made true during the __intel_backlight_enable call).
We face these scenarios in some compositors during the pass key phase where the compositor is still totally not doing everything and does not send
us any explicit brightness value to set thinking eDP would have some basic default value of it's own . We end up getting a 0 from DPCD and we enable and set the backlight enable with 0 value which anyways later causes us to call backlight disable.
In this case during authentication in some compositors like Fedora there are cases where we do not get a explicitly backlight value till the user has to blindly enter their
Passkey, after which the compositor sends us some sane value which we then program.

There's a long history of problems with the PWM backlight unexpectedly
going from 0 to max.

Right but at least with this now luminance values will continue if DPCD maintains its state if we get a value back, otherwise we set a
Default value.
Can we proceed with getting this merged ? Would really help the user.

What's the brightness control mode *before* we enable luminance control?

When taking over, we should try to read the current brightness setting
with the current brightness control method. If we're switching to
luminance control, the existing luminance value is meaningless.

AFAICT drm_edp_backlight_probe_state() uses bl->luminance_set to
determine the value to read, not the current mode. At a glance, seems
wrong to me.

Of course, regressions have priority, so a revert should also be a
consideration before quickly going for adding level = max in there.

The real problem with quick fixes to help the user is that they have the
potential to make it a lot harder for a lot more users and developers in
the long run.

Luminance mode is the current mode. Which we determine that by checking different capabilities from the and setting them
In this case aux_set and aux_enable to represent them.

In this case aux_set = 1 and luminance_set = 1 which means we are in luminance mode

From what I can see
We are in Luminance Mode to begin with. From logs there is a level mentioned in VBT should we use that ?

VBT here says use level 255 would it be okay if we set that to level as VBT level, if no value is returned from DPCD panel.

The question is not about the panel's *ability* to use luminance mode,
it's about whether that mode was set and in use by GOP/pre-os.

I did some more digging and for aux_set enabled we really do not need to do get_backlight 
And read register again that is filled in probe state and fills up the current_level variable that can be use.
Check drm_edp_backlight_probe_state.
I also found this little comment there

        /*
         * If we're not in DPCD control mode yet, the programmed brightness value is meaningless and
         * the driver should assume max brightness
         */
        return bl->max;

So this was a policy that was decided during VESA AUX Backlight implementation time. Also that Mode will not be DPCD
Initially and will change later during backlight enable so we get to assume max brightness . That should be okay to do with
Luminance_set case too then.

The comment says, if the panel is not in DPCD control mode, the value in
DPCD is meaningless.

Ditto, if the panel is not in luminance control mode (or whatever the
specific name for it is), the luminance value in DPCD is meaningless.

However, if the panel is in DPCD control mode but not in luminance
control mode, we should be able to read the non-luminance DPCD
brightness value and use that.

BR,
Jani.

picture we need to take care that we do not enable PWM function if
luminance_set is set.

[Suraj Kandpal]

intel_dp_aux_supports_hdr_backlight() prints debug message for
intel HDR backlight version. This is fine when dealing with eDP 1.4b
and lower. When we are talking about eDP 1.5 it causes confusion in
logs since we need to use VESA AUX backlight functions but this
print causes confusion as to which path code take.
Short circuit this function with a eDP version check. Make sure this
is only called if eDP <= 1.4b

[PATCH v3 8/8] drm/i915/backlight: Use default/max brightness for INTEL AUX HDR backlight init

[Suraj Kandpal]

If the brightness fetched from VBT/previous state is 0 on backlight
initialization, then set the brightness to a default/max value.
Whenever the minimum brightness is reported as 0 there are chances
we maybe sometimes end up with blank screen. This confuses the user
into thinking the display is acting weird. This occurs in eDP 1.4b
when we use proprietary INTEL AUX HDR DPCD registers to manipulate
brightness via luminance values.

v1 -> v2:
- Let users set brightness to 0, make it so that it's just not
done by default (Arun)

v1 -> v2:
- Update commit header & message (Arun)

Same here, .enabled is still based on level != 0 above.
