Hi Mauro,
You might want to read the patches more carefully, because what you're
demanding is what my patches do. Short summary:
- if STRICT_FOLLOW_PFN is set:
a) normal memory is handled as-is (i.e. your example works) through
the addition of FOLL_LONGTERM. This is the "pin the pages correctly"
Functions (disable_all_writeback_pipes_for_stream &
dc_enable_stereo & dc_post_update_surfaces_to_stream)
always return true, there is no need to keep the return value.
This change is to make the code a bit more readable.

Add it in edid quirks to force using DPCD backlight control.
Then the brightness can be controlled.

Hello,

In function dpu_core_irq_enable & dpu_core_irq_disable, when
some index enable or disable failed, return value will be
covered by next success index. Upper call function will not

BOE panel with ID 2270 claims both PWM_PIN_CAP and AUX_SET_CAP backlight
control bits, but default chip backlight failed to control brightness.
Check AUX_SET_CAP and proceed to check quirks or VBT backlight type.
DPCD can control the brightness of this pannel.
