* Fix a hole in the scheduler where collisions between waking blocked threads ↵Michael Sevakis2007-03-26
| | | | | | in mutexes with interrupts waking blocked threads in message queues can occur. Queue posts will put the threads on a separate list that is then added to the running list with IRQs disabled on the next task switch or CPU wakeup. Basically no overhead for other operations. Seems a likely cause of my occasional observation of the backlight fade causing playback threads to stop running and a recently reported blocking violation upon USB plugging. Time will tell but banging the backlight on and off frequently hasn't hiccuped again for me on H120. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12915 a1c6a512-1295-4272-9138-f99709370657

* Fix problem with recording screen creep and bag a bigfoot. Voice clips ↵Michael Sevakis2007-03-06
| | | | | | aren't long enough now to untrigger the thread boost that was supposed to be applied to the codec thread. The voice thread was needlessly boosting the codec thread and leaving it boosted which explains the encoders' ability to flood the output buffer when everything else was stopped in its tracks. Check which thread is calling pcmbuf_under_watermark and only initiate the boost when it's the codec thread. Always return the codec thread to its usual priority in pcmbuf_play_stop. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12649 a1c6a512-1295-4272-9138-f99709370657
* Dual core support for PP502x players (iPod G4 and later, iriver h10, Sansa - ↵Daniel Ankers2007-03-04
| | | | | | iPod G3 will be coming soon.) This allows threads to be run on either core provided that all communications between the cores is done using uncached memory. There should be no significant change in battery life from doing this. Documentation (on the RockboxKernel wiki page) will follow shortly. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12601 a1c6a512-1295-4272-9138-f99709370657

* Thread API enhancements.Brandon Low2006-11-11
| | | | | | | | 1) block_thread -> block_thread + block_thread_w_tmo -- this call was always used in distinct ways so having one call with a conditional was ugly. 2) enhance Slasheri's scheduler controlled boost concept. now any thread may trigger a boost which will last until that thread next sleeps. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11509 a1c6a512-1295-4272-9138-f99709370657

* Big Patch adds primarily: Samplerate and format selection to recording for ↵Michael Sevakis2006-11-06
| | | | | | SWCODEC. Supprort for samplerates changing in playback (just goes with the recording part inseparably). Samplerates to all encoders. Encoders can be configured individually on a menu specific to the encoder in the recording menu. File creation is delayed until flush time to reduce spinups when splitting. Misc: statusbar icons for numbers are individual digits to display any number. Audio buffer was rearranged to maximize memory available to recording and properly reinitialized when trashed. ColdFire PCM stuff moved to target tree to avoid a complicated mess when adding samplerate switching. Some needed API changes and to neaten up growing gap between hardware and software codecs. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11452 a1c6a512-1295-4272-9138-f99709370657
