Subject: [PATCH 2/2] Revert "drm/i915/edp: Allow alternate fixed mode for eDP
|
||||
if available."
|
||||
|
||||
This reverts commit dc911f5bd8aacfcf8aabd5c26c88e04c837a938e.
|
||||
|
||||
Per the report, no matter what display mode you select with xrandr, the
|
||||
i915 driver will always select the alternate fixed mode. For the
|
||||
reporter this means that the display will always run at 40Hz which is
|
||||
quite annoying. This may be due to the mode comparison.
|
||||
|
||||
But there are some other potential issues. The choice of alt_fixed_mode
|
||||
seems dubious. It's the first non-preferred mode, but there are no
|
||||
guarantees that the only difference would be refresh rate. Similarly,
|
||||
there may be more than one preferred mode in the probed modes list, and
|
||||
the commit changes the preferred mode selection to choose the last one
|
||||
on the list instead of the first.
|
||||
|
||||
(Note that the probed modes list is the raw, unfiltered, unsorted list
|
||||
of modes from drm_add_edid_modes(), not the pretty result after a
|
||||
drm_helper_probe_single_connector_modes() call.)
|
||||
|
||||
Finally, we already have eerily similar code in place to find the
|
||||
downclock mode for DRRS that seems like could be reused here.
|
||||
|
||||
Back to the drawing board.
|
||||
|
||||
Note: This is a hand-crafted revert due to conflicts. If it fails to
|
||||
backport, please just try reverting the original commit directly.
