Subject: [PATCH v2 0/6] drm/vc4: kms: Misc fixes for HVS commits
Date: Wed, 17 Nov 2021 10:45:21 +0100	[thread overview]
Message-ID: <20211117094527.146275-1-maxime@cerno.tech> (raw)

Hi,

The conversion to DRM commit helpers (f3c420fe19f8, "drm/vc4: kms: Convert to
atomic helpers") introduced a number of issues in corner cases, most of them
showing themselves in the form of either a vblank timeout or use-after-free
error.

These patches should fix most of them, some of them still being debugged.

Maxime

Changes from v1:
  - Prevent a null pointer dereference

Maxime Ripard (6):
  drm/vc4: kms: Wait for the commit before increasing our clock rate
  drm/vc4: kms: Fix return code check
  drm/vc4: kms: Add missing drm_crtc_commit_put
  drm/vc4: kms: Clear the HVS FIFO commit pointer once done
  drm/vc4: kms: Don't duplicate pending commit
  drm/vc4: kms: Fix previous HVS commit wait
