[libcamera-devel] [PATCH v1 0/6] libcamera: Improve debug messages in V4L2 compat layer

[Laurent Pinchart]

Hello,

This patch series improves the debug messages printed by the file
operation handlers in the V4L2 compat layer.

Before the series, the log messages printed the file descriptor of the
V4L2 file as an integer:

[207:37:26.959469077] [32330] DEBUG V4L2Compat v4l2_camera_proxy.cpp:531 Servicing vidioc_querybuf fd = 3
[207:37:26.959608478] [32330] DEBUG V4L2Compat v4l2_camera_proxy.cpp:549 Servicing vidioc_qbuf, index = 0 fd = 3

Now, the file path is printed as well, and the message is formated as a
function call for better readability:

[207:32:30.769491737] [32181] DEBUG V4L2Compat v4l2_camera_proxy.cpp:544 [/dev/video2 (fd:3)] vidioc_querybuf()
[207:32:30.769565454] [32181] DEBUG V4L2Compat v4l2_camera_proxy.cpp:563 [/dev/video2 (fd:3)] vidioc_qbuf(index=0)
