Descriptions

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Disable PSR-SU on Parade 08-01 TCON too

Stuart Hayhurst has found that both at bootup and fullscreen VA-API video
is leading to black screens for around 1 second and kernel WARNING [1] traces
when calling dmub_psr_enable() with Parade 08-01 TCON.

These symptoms all go away with PSR-SU disabled for this TCON, so disable
it for now while DMUB traces [2] from the failure can be analyzed and the failure
state properly root caused.

(cherry picked from commit afb634a6823d8d9db23c5fb04f79c5549349628b)

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Deshabilitar PSR-SU también en Parade 08-01 TCON Stuart Hayhurst ha descubierto que tanto en el arranque como en pantalla completa, el vídeo VA-API provoca pantallas negras durante alrededor de 1 segundo y rastros de ADVERTENCIA [1] en el kernel al llamar a dmub_psr_enable() con Parade 08-01 TCON. Todos estos síntomas desaparecen con PSR-SU deshabilitado para este TCON, así que deshabilítelo por ahora mientras se pueden analizar los rastros DMUB [2] del fallo y se puede determinar correctamente el estado del fallo.
