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_v12 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 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 changes in version 8: - Add V4L2_BUF_CAP_SUPPORTS_SET_MAX_BUFS and new 'max_buffers' field in v4l2_create_buffers structure to report the maximum number of buffers that a queue could allocate. - Add V4L2_BUF_CAP_SUPPORTS_DELETE_BUFS to indicate that a queue support DELETE_BUFS ioctl. - Make some test drivers use more than 32 buffers and DELETE_BUFS ioctl. - Fix remarks done by Hans - Move "media: core: Rework how create_buf index returned value is computed" patch to the top of the serie.
