[PATCH 0/5] Fix occasional software ISP assertion error on stop

[Milan Zamazal]

When software ISP is stopped, there can be pending messages in the
message queue that will attempt to call the already stopped IPA,
resulting in an assertion error like this:

  FATAL default soft_ipa_proxy.cpp:456 assertion "state_ == ProxyRunning" failed in processStatsThread()

This patch series fixes the problem and also attempts to prevent other
problems related to message handling when or after software ISP is
stopped.

Milan Zamazal (5):
  libcamera: software_isp: Emit ispStatsReady only if IPA is running
  libcamera: software_isp: Handle queued output buffers on stop
  libcamera: software_isp: Handle queued input buffers on stop
  libcamera: base: Fix formatting in thread.cpp
  libcamera: software_isp: Modify dispatching messages on stop
