Replace the dmabuf import patch with the two series that it grow into during upstreaming, shipping in the next libcamera release. This will: 1. Improve performance for all devices using the GPU-ISP, including those not able to use dmabuf import. 2. Simplify debugging. 3. Ensure the patches get enough testing before the upstream release. While on it backport some additional patches: 1. A follow-up patch adding the last required step to allow dmabuf import for input buffers to work in almost all cases *if* the V4L2 driver handles custom bytesperline requests for bayer formats. 2. A small logging fix 3. A fix for bad bottom lines of pixels seen on some devices. This is the only patch with visual impact - and a quite desirable one. 4. A patch to log the used driver for easier debugging. This leaves us with only two downstream patches, both specific to the PinePhone (OG). Finally, add a "py3-$pkgname-pyc:pyc" subpackage in order to stay in sync with the upstream package. Part-of: <https://gitlab.postmarketos.org/postmarketOS/pmaports/-/merge_requests/8650>

Subject: [PATCH 01/13] debayer_egl: Include stats computation into benchmark
|
|
|
|
The following commit will allow debayering on the GPU and stats
|
|
computation on the CPU to happen in parallel, requiring this change in
|
|
order to keep the benchmark meaningful.
|
|
|
|
Do the change first in order to make before/after comparisons simpler.
