2024-09-27pipeline: simple: Increase buffer count to fourRobert Mader
Which is not only what many other pipeline handlers use, but also a good lower limit when dealing with DRM and similar APIs. Even Mesas EGL and Vulkan WSI implementations use for the reason outlined in mesa commit 992a2dbba80aba35efe83202e1013bd6143f0dba: > When the compositor is directly scanning out from the application's buffer it > may end up holding on to three buffers. These are the one that is is currently > scanning out from, one that has been given to DRM as the next buffer to flip > to, and one that has been attached and will be given to DRM as soon as the > previous flip completes. When we attach a fourth buffer to the compositor it > should replace that third buffer so we should get a release event immediately > after that. This patch therefore also changes the number of buffer slots to 4 > so that we can accomodate that situation. Given the popularity of this buffer number the bump should be unlikely to cause problems. At the same time it may help with performance or even work around glitches. The previous number was introduced in commit a8964c28c80fb520ee3c7b10143371081d41405a without mentioning a specific reason against the change at hand.

2024-09-27libcamera: software_isp: Update black level only on exposure changesMilan Zamazal
The black level is likely to get updated, if ever, only after exposure or gain changes. Don't compute its possible updates if exposure and gain are unchanged. It's probably not worth trying to implement something more sophisticated. Better to spend the effort on supporting tuning files.

2024-09-27libcamera: software_isp: Move exposure+gain to an algorithm moduleMilan Zamazal
This is the last step to fully convert software ISP to Algorithm-based processing. The newly introduced frameContext.sensor parameters are set, and the updated code moved, before calling Algorithm::process() to have the values up-to-date in stats processing.

2024-09-27libcamera: software_isp: Use DelayedControlsMilan Zamazal
Use the standard libcamera mechanism to report the "current" controls rather than delaying updates by counting from the last update. A problem is that with software ISP we cannot be sure about the sensor delay. The original implementation simply skips exposure updates for 2 frames, which should be enough in most cases. After this change, we assume the delay being exactly 2 frames, which may or may not be correct and may work with outdated values if the delay is shorter. According to Kieran, the wrong parts are also wrong on the IPU3/RKISP1/Mali pipelines and only RPi have this correct. We need to fix this, by correctly specifying the gains in the libipa camera sensor helpers. The sooner the better because this change could introduce a risk of increasing oscillations. This patch also prepares moving exposure+gain to an algorithm module where the original delay mechanism would be a (possibly unnecessary) complication. Resolves software ISP TODO #11 + #12.

2024-09-27libcamera: software_isp: Use floating point for color parametersMilan Zamazal
It's more natural to represent color gains as floating point numbers rather than using a particular pixel-related representation. double is used rather than float because it's a more common floating point type in libcamera algorithms. Otherwise there is no obvious reason to select one over the other here. The constructed color tables still use integer representation for efficiency. Black level still uses pixel (integer) values, for consistency with other libcamera parts.

2024-09-27libcamera: software_isp: Move color handling to an algorithm moduleMilan Zamazal
After black level handling has been moved to an algorithm module, white balance and the construction of color tables can be moved to algorithm modules too. This time, the moved code is split between stats processing and parameter construction methods. It is also split to two algorithm modules: - White balance computation. - Gamma table computation and color lookup tables construction. While this applies the color gains computed by the white balance algorithm, it is not directly related to white balance. And we may want to modify the color lookup tables in future according to other parameters than just gamma and white balance gains. Gamma table computation and color lookup tables construction could be split to separate algorithms too. But there is no big need for that now so they are kept together for simplicity. This is the only part of the software ISP algorithms that sets the parameters so emitting setIspParams can be moved to prepare() method. A more natural representation of the gains (and black level) would be floating point numbers. This is not done here in order to minimize changes in code movements. It will be addressed in a followup patch.

2024-09-27libcamera: software_isp: Move black level to an algorithm moduleMilan Zamazal
The black level determination, already present as a separate class, can be moved to the prepared Algorithm processing structure. It is the first of the current software ISP algorithms that is called in the stats processing sequence, which means it is also the first one that should be moved to the new structure. Stats processing starts with calling Algorithm-based processing so the call order of the algorithms is retained. Movement of this algorithm is relatively straightforward because all it does is processing stats. The comment about getting black level from the tuning files is dropped. The black level will be taken from CameraSensorHelper if available and that will be implemented in one of the followup patches. Black level is now recomputed on each stats processing. In a future patch, after DelayedControls are used, this will be changed to recompute the black level only after exposure/gain changes. The black level depends on the sensor used, the computed value can be reused in a followup capture sessions with the same sensor. Thus it is sufficient to (re)set the initial value in BlackLevel::init.

This patch adds frame and bufferId arguments to stats related calls. Although the parameters are currently unused, because frame ids are not tracked and used and the stats buffer is passed around directly rather than being referred by its id, they bring the internal APIs closer to their counterparts in hardware pipelines. It serves as a preparation for followup patches that will introduce: - Frame number tracking in order to switch to DelayedControls (software ISP TODO #11 + #12). - A ring buffer for stats in order to improve passing the stats (software ISP TODO #2). Frame and buffer ids are unrelated for the given purposes but since they are passed together at the same places, the change is implemented as a single patch rather than two, basically the same, patches.

2024-09-27libcamera: software_isp: Define skeletons for IPA refactoringMilan Zamazal
Software ISP image processing algorithms are currently defined in a simplified way, different from other libcamera pipelines. This is not good for several reasons: - It makes the software ISP code harder to understand due to its different structuring. - Adding more algorithms may make the code harder to understand generally. - Mass libcamera code changes may not be easily applicable to software ISP. - Algorithm sharing with other pipelines is not easily possible. This patch introduces basic software ISP IPA skeletons structured similarly to the other pipelines. The newly added files are currently not used or compiled and the general skeleton structures don't contain anything particular. It is just a preparation step for a larger refactoring and the code will be actually used and extended as needed in followup patches.

This allows applications to query the ControlId for the names of the enum values, so that they can be displayed on a UI, for example.

2024-09-23ipa: libipa: Add generic Interpolator classStefan Klug
The MatrixInterpolator is great for interpolation of matrices for different color temperatures. It has however one limitation - it can only handle matrices. For LSC it would be great to interpolate the LSC tables (or even polynomials) using the same approach. Add a generic Interpolator class based on the existing MatrixInterpolator. This class can be adapted to any other type using partial template specialization.

2024-09-23libcamera: yaml-parser: Differentiate between empty and empty stringStefan Klug
When accessing a nonexistent key on a dict the YamlObject returns an empty element. This element can happily be cast to a string which is unexpected. For example the following statement: yamlDict["nonexistent"].get<string>("default") is expected to return "default" but actually returns "". Fix this by introducing an empty type to distinguish between an empty YamlObject and a YamlObject of type value containing an empty string. For completeness add an isEmpty() function and an explicit cast to bool to be able to test for that type. Extend the tests accordingly.

2024-09-20libcamera: debayer_cpu: Sync DMABUFsRobert Mader
Using `DMA_BUF_IOCTL_SYNC` is required for DMABUFs in order to ensure correct output. Not doing so currently results in occasional tearing and/or backlashes in GL/VK clients that use the buffers directly for rendering. An alternative approach to have the sync code in `MappedFrameBuffer` was considered but rejected for now, in order to allow clients more flexibility. While the new helper is added to an annoymous namespace, add timeDiff to the same namespace and remove the static definition as a drive by.

The handling for the sequence number validation within V4L2VideoDevice::dequeueBuffer makes use of a std::optional, which can be used as a boolean in conditional statements. This has the impact in this use case that it can be mis-read to be interpretting the value for firstFrame_ which is assigned as the buf.sequence. Remove this potential for confusion by making it clear that the first frame handling is only performed when firstFrame_ does not have a value assigned.
