Subject: [PATCH v13 00/56] Add DELETE_BUF ioctl
Date: Thu, 19 Oct 2023 14:51:26 +0200 [thread overview]
Message-ID: <20231019125222.21370-1-benjamin.gaignard@collabora.com> (raw)
Unlike when resolution change on keyframes, dynamic resolution change
on inter frames doesn't allow to do a stream off/on sequence because
it is need to keep all previous references alive to decode inter frames.
This constraint have two main problems:
- more memory consumption.
- more buffers in use.
To solve these issue this series introduce DELETE_BUFS ioctl and remove
the 32 buffers limit per queue.
VP9 conformance tests using fluster give a score of 210/305.
The 20 resize inter tests (vp90-2-21-resize_inter_* files) are ok
but require to use postprocessor.
Kernel branch is available here:
https://gitlab.collabora.com/benjamin.gaignard/for-upstream/-/commits/remove_vb2_queue_limit_v13
GStreamer branch to use DELETE_BUF ioctl and testing dynamic resolution
change is here:
https://gitlab.freedesktop.org/benjamin.gaignard1/gstreamer/-/commits/VP9_drc
changes in version 13:
- Fix typo and wording in commits messages.
- Only apply V4L2_BUF_CAP_SUPPORTS_SET_MAX_BUFS on createbufs ioctl
- Fix queue setup test in test-drivers
changes in version 12:
- Change flag name to V4L2_BUF_CAP_SUPPORTS_SET_MAX_BUFS.
- Rework some commits message.
- Change vb2_queue_or_prepare_buf() prototype.
- Rework patches where 'min_buffers_needed' was badly used.
changes in version 11:
- Patches ordering:
1 to 3: clean up
3 to 42: use vb2_get_buffer() and vb2_get_num_buffers()
43 to 46: allow to use more than 32 buffers per queue
47 to 50: allow verisilicon driver to do VP9 dynamic resolution change
(which was the main purpose of this work)
51 to 56: prepare and introduce delete buffers feature.
- Add a patch to rename 'off' to offset.
- Add maintainers CC to drivers patches
changes in version 10:
- Make BUFFER_INDEX_MASK definition more readable
- Rebase on media_stage/master branch and add a patch for nuvoton
driver.
- Fix issue on patch 13
changes in version 9:
- BUFFER_INDEX_MASK now depends on PAGE_SHIFT value to match
architectures requirements.
- Correctly initialize max_num_buffers in vb2_core_queue_init()
- run 'test-media -kmemleak mc' on top of the series and on patches 1 to 47 without failures.
- fix compilation issue in patch 50
