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.

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.

This patch extends that by actually providing the frame id and passing it through to the stats processor. The frame id is taken from the request sequence number, the same as in hardware pipelines. Dear reviewers: I'm confused even after looking at commit 6084217cd3b52ba5677e3ca2de0e21008fdaa735. What's the relationship between requests, buffers and frames? It's not 1:1:1 or is it? Could you please provide some explanation that could be put here?

As there are currently no control knobs in software ISP nor the corresponding queueRequest call chain, the patch also introduces the queueRequest methods and calls from the pipeline to the IPA. This is preparation only since there are currently no Algorithm based algorithms defined and no current software ISP algorithms support control knobs.

This is preparation only since there are currently no Algorithm based algorithms defined. As software ISP currently doesn't produce any metadata, a dummy and unused metadata instance is created to satisfy Algorithm::process API. This should be changed in future.

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. 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.

This time, the moved code is split between stats processing and parameter construction methods. 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.

Otherwise there is no obvious reason to select one over the other here. The constructed color tables still use integer representation for efficiency.

MY SPECULATION -- valid or not?: 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. 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.
