2024-06-25libcamera: v4l2_subdevice: Add new metadata formatsLaurent Pinchart
Support the newly introduced V4L2 media bus formats for metadata. This includes generic metadata formats, and two sensor-specific embedded data formats. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2024-06-25v4l2: v4l2_compat: Move `open*()` flag check into functionBarnabás Pőcze
This commit moves the check that determines whether the mode argument of `open*()` exists into a separate function. With that, the check is fixed because previously it failed to account for the fact that `O_TMPFILE` is not a power of two. Furthermore, add `assert()`s in the fortified variants that ensure that no mode is required by the specified flags.

2024-06-25v4l2: v4l2_compat: Fix redirect from `__open(at)64_2()`Barnabás Pőcze
To avoid confusion, have `__open64_2()` and `__openat64_2()` delegate to `open64()` and `openat64()`, respectively, instead of `open()` and `openat()`. This does not change the behaviour because `V4L2CompatManager::instance()->openat()` calls `openat64()` internally, and that adds the `O_LARGEFILE` flag unconditionally.

2024-06-24libcamera: yaml_parser: Add support for float typesLaurent Pinchart
The YamlObject::get<T>() function template has a specialization for double but not for float. When used in an IPA module, the issue is caught at module load time only, when dynamic links are resolved, causing errors such as Failed to open IPA module shared object: /usr/lib/libcamera/ipa_rkisp1.so: undefined symbol: _ZNK9libcamera10YamlObject6GetterIfE3getERK_ Fix it by adding a float specialization.

generateConfiguration() called validate() as a final step, causing the stride and frameSize fields in StreamConfiguration to be filled in based on the pixel format and width/height. If a user application did not clear the stride field when setting up a custom pixel format and width/height, the pipeline handler would respect this stride and possibly overallocate buffers with a larger stride than needed. Fix this by removing the call to validate() completely, leaving the stride and frameSize fields defaulting to 0. Removal of this call is inconsequential as we hard-code a valid configuration for Raspberry Pi platforms in generateConfiguration().
