[libcamera-devel] [PATCH v3 0/6] IPU3 Stability

[Kieran Bingham]

A reduced set of patches from the previous iteration of the IPU3
Stability developments.


Patches [1/6] and [2/6] are split from a test patch provided to me by
Laurent, where I have added the commit messages.

These ensure that messages sent by the IPA are handled correctly and do
not race at stop() time

Patch [3/6] was identified by valgrind and fixes an issue related to
uninitialised accesses on the buffers. It has been reworked since v2.

Patch [4/6] fixes the ordering of stopping the IPA and video devices,
with [5/6] fixing an issue which previously completed requests (and
associated frame info) before all buffers had completed.

Finally patch [6/6] moves an asynchronous callback out of the
synchronous configure() call, and into start(). This is not expected to
be a substantial change in functionality currently, but should be
considered in follow on developments with the IPA.

Kieran Bingham (4):
  libcamera: buffer: Initialise status
  libcamera: pipeline: ipu3: Stop IPA before stopping devices
  libcamera: pipeline: ipu3: Do not mark metadata complete early
  ipa: ipu3: Do not set controls during configure

Laurent Pinchart (2):
  utils: ipc: proxy: Assert asynchronous calls execute in the running
    state
  utils: ipc: proxy: Process pending messages
