Subject: [PATCH] drm: Separate BOE and SDC OLED Deck panel valid refresh rates
|
||
|
|
|
||
|
|
OLED Decks with BOE panels seem to struggle with a few different
|
||
|
|
specific modesets (51hz/55hz/65hz) that SDC panels have no issues with.
|
||
|
|
To work around this, let's make use of Gamescope recognizing each
|
||
|
|
display manufacturer to correct the bad modesets while leaving
|
||
|
|
SDC panel units alone. This can be reverted if an underlying cause can
|
||
|
|
be found in the kernel in the future.
