- drm/nouveau: don't attempt to schedule hpd_work on headless cards
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau: don't attempt to schedule hpd_work on headless cards
If the card doesn't have display hardware, hpdwork and hpdlock are left uninitialized which causes BUG when attempting to schedule hpd_work on runtime PM resume.
Fix it by adding headless flag to DRM and skip any hpd if it's set.
