Descriptions
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Disable idle reallow as part of command/gpint execution
[Why]
Workaroud for a race condition where DMCUB is in the process of
committing to IPS1 during the handshake causing us to miss the
transition into IPS2 and touch the INBOX1 RPTR causing a HW hang.
[How]
Disable the reallow to ensure that we have enough of a gap between entry
and exit and we're not seeing back-to-back wake_and_executes.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amd/display: deshabilite la reasignación inactiva como parte de la ejecución del comando/gpint [Por qué] Workaroud para una condición de ejecución en la que DMCUB está en el proceso de comprometerse con IPS1 durante el protocolo de enlace que causa Nos perdemos la transición a IPS2 y tocamos el RPTR de INBOX1 provocando un bloqueo del HW. [Cómo] Deshabilite la reallow para asegurarnos de que tengamos un espacio suficiente entre la entrada y la salida y que no veamos wake_and_executes consecutivos.
