channel.c/channel_if.m: - Macros cleanups, prefer inlined min() over MIN(). - Rework chn_read()/chn_write() for better dead interrupt detection policy. Reduce scheduling overhead by doing pure 5 seconds sleep before giving up, instead of several cycle of brute micro sleeping. - Avoid calling wakeup_one() for non-sleeping channel (for example, vchan parent channel). - EWOULDBLOCK -> EAGAIN. - Fix possible divide-by-zero panic on chn_sync(). - Re-enforce ^2 blocksize policy, since there are too many broken userland apps that blindly assume it without even trying to do serious calculations. - New channel method - CHANNEL_SETFRAGMENTS(), a refined version of CHANNEL_SETBLOCKSIZE(). It accept _both_ blocksize and blockcount arguments, so the driver internals will have better hints for buffering and timing calculations. - Hook FEEDER_SWAPLR into feederchain building process. feeder_fmt.c: - Unified version of various filters, avoiding duplications. - malloc()less feeder_fmt. Informations can be retrieved dynamically by doing table lookup on static data. For cases such as converting from stereo to mono or reducing bit depth where input data is larger than output, cycle remaining available free space until it has been exhausted and start kicking 8 bytes reservoir space from there to complete the remaining requested count. - Introduce FEEDER_SWAPLR. Few super broken hardwares (found on several extremely cheap uaudio stick, possibly others) mistakenly wired left and right channels wrongly, screwing output or input. |
