Merge remote-tracking branch 'origin/master' into next
libcamera v0.7.2
This release brings 113 commits, and interestingly fixes two separate
saturation handling bugs in both the SoftISP and the Raspberry Pi IPA
independently. In particular the fixes to the SoftISP mean we can look forward
to tuning cameras on laptops and mobile phones with real CCMs now.
Also on the SoftISP 12-bit formats are now supported, black level correction is
'fixed' and there are interesting performance improvements with eGL buffer
caching.
Within the IPA handling, we have added support for Sony IMX678, as well as
Omnivision OV08x40 and OV01A10, and moved to a proportional AGC algorithm for
the simple pipeline handler.
Otherwise we have lots of fixes and improvements to Raspberry Pi, and ongoing
cleanup and improvements to many areas of core. It may be noteworthy for
distributions that the virtual pipeline handler is now enabled by default from
meson.

Integration Overview:
ABI:
The abi-compliance checker reports 100% *binary* compatibility in this release,
so the SONAME is maintained at 0.7.
Validating ABI compatibility between v0.7.1 and v0.7.2
Preparing, please wait ...
Comparing ABIs ...
Comparing APIs ...
Creating compatibility report ...
Binary compatibility: 100%
Source compatibility: 97.9%
Total binary compatibility problems: 0, warnings: 2
Total source compatibility problems: 13, warnings: 2
These source compatibility problems are bisected to 597a5bb ("libcamera:
bound_method: Use std::apply") and this looks to be a false positive and as far
as I can tell do not actually prevent any external application compiling
against libcamera.
The following commits in this release relate to either a bug fix or an
improvement to an existing commit.

- libcamera: egl: Don't depend on libdrm

libcamera Debian release 0.7.1+rpt20260429-1
Merge branch 'master' into next Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
libcamera v0.7.1
This release brings 142 commits with the largest developments in the core of
libcamera components. Perhaps the most obvious is that we now use C++20 for the
project. The Configuration file handling has had a substantial rework with
updates to the yaml_parser.
The RKISP1 IPA has now added a new Hue control which brought with it a rework
of how we manage fixed point arithmetic with the Quantized class. I hope this
makes it easier to convey types with hardware operations.
The SoftISP has the ability to perform CPU debaying with multiple threads which
helps throughput on platforms such as the Arduino Uno Q.
The Mali-C55 pipeline handler now has full support for the RZG2LCRU and inline
handling which enables camera support on the Renesas RZ/V2H and RZ/V2NP
platforms.
And of interest in the apps components, the gstreamer plugin now has the
ability to select and configure the sensor mode configuration properties.
Finally a new script "libcamera-bug-report" is available to be packaged which
will help users identify issues when reporting bugs.
