[libcamera-devel] [PATCH v2 00/11] libcamera: Add event notification and timers

[Laurent Pinchart]

Hello everybody,

Here's the second version of the event notification and timer support
patch series for libcamera.

The series starts with small cleanups and changes (01/11 to 04/11), and
then adds a signal/slot mechanism (05/11) that serves to implement event
nofication in the event notifier and the timer (06/11). Patch 07/11 adds
a default poll()-based implementation of the event dispatcher that is
used by libcamera when the application doesn't provide its own
implementation. Patches 08/11 to 11/11 finally add corresponding test
cases.

I've incorporated (to the best of my knowledge) all the feedback I've
received on v1. Please see individual patches for changelogs.

  libcamera: Add event notification infrastructure
  libcamera: Add a poll-based event dispatcher
  test: Rename list test to list-cameras
  test: Add signal/slot test
