Descriptions

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

drm/amd/display: Wake DMCUB before executing GPINT commands

[Why]
DMCUB can be in idle when we attempt to interface with the HW through
the GPINT mailbox resulting in a system hang.

[How]
Add dc_wake_and_execute_gpint() to wrap the wake, execute, sleep
sequence.

If the GPINT executes successfully then DMCUB will be put back into
sleep after the optional response is returned.

It functions similar to the inbox command interface.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Activa DMCUB antes de ejecutar comandos GPINT [Por qué] DMCUB puede estar inactivo cuando intentamos interactuar con el HW a través del buzón GPINT, lo que provoca un bloqueo del sistema. [Cómo] Agregue dc_wake_and_execute_gpint() para ajustar la secuencia de activación, ejecución y suspensión. Si GPINT se ejecuta correctamente, DMCUB volverá a entrar en modo de suspensión después de que se devuelva la respuesta opcional. Funciona de manera similar a la interfaz de comando de la bandeja de entrada.
