Working on previous weeks' patches. Received lots of useful feedback on most of them. sound: Refactor the format conversion framework: https://reviews.freebsd.org/D47932 - Implemented unit tests for the format conversion functions and fixed some regressions. - Made the conversion functions alignment-agnostic to reduce code size and complexity. - Still addressing some comments. sound: Allocate vchans on-demand: https://reviews.freebsd.org/D47917 - Addressed comments, fixed bugs. sound: Implement AFMT_FLOAT support: https://reviews.freebsd.org/D47638 - Added support in feeder_chain.c, feeder_rate.c and feeder_volume.c. - Rebase to work with D47932. - Define AFMT_F32_OE. - Making the implementation alignment-agnostic, similar to how D47932 works for the other formats. - Writing unit tests. sound: Bail out early if a format is not supported: https://reviews.freebsd.org/D48031 sound: Remove macro magic from pcm/feeder_eq.c: https://reviews.freebsd.org/D48032 sound: Remove macro magic from pcm/feeder_matrix.c: https://reviews.freebsd.org/D48035 sound: Remove feed_matrix_apply_generic(): https://reviews.freebsd.org/D48036 sound: Refactor the format conversion framework: https://reviews.freebsd.org/D47932 sound: Do not return an error from chn_notify() if the children list is empty: https://reviews.freebsd.org/D48156 sound: Call vchan_destroy() on vchan_create() failure: https://reviews.freebsd.org/D48183 sound: Do not fail from vchan_destroy() if children list is empty: https://reviews.freebsd.org/D48185 2024Q4 report committed: https://cgit.freebsd.org/doc/commit/?id=cb4812ed9af51a701f72874e54fcfbf97f5e2346 FreeBSD Foundation laptop project - Getting more familiar with snd_hda(4) internals to start working on automatic pin-patching. This is an experimental project, so it is not guaranteed to be successful. - Discussed with emaste@ about the first iteration's project (automatic pin-patching). - Attended Laptop and Desktop Working Group call. This work is sponsored by the FreeBSD Foundation. Christoshelp
