bfb281ff63 Messages queues must be guarded on both ends or else it's a race between detecting a message present and missing a wakeup on thread about to wait. Keeping IRQs from interacting with the scheduler would be preferable but this should do at the moment. Add more detailed panic info regarding blocking violations so we know who. Make panicf function well enough on Gigabeat and PortalPlayer targets. Move the core sleep instructions into a CPU-specific inline to keep thing organized.

d95c39072a Portal Player: Add invalidate_icache and flush_icache. Flush the cache on the core for newborn threads. In doing so, move more ARM stuff to the target tree and organize it to make a clean job of it. If anything isn't appropriate for some particular device give a hollar or even just fix it by some added #ifdefing. I was informed that the PP targets are register compatible so I'm going off that advice. The Sansa likes it though.

66258a30a4 Make scheduler functions thread safe core wise. A big step towards playback running on COP (not yet possible because more protection on file system level is necessary).

165f62d0cd Fix a hole in the scheduler where collisions between waking blocked threads 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.

dee43ece20 Put an end to priority inversion in the ata driver. Gave up trying to have fully atomic dual use mutexes so just replaced the ata driver locking with spins. Maybe I'll have better luck later. Things should run smoothly with database updates and such happening in the background.

b425de71df Fix problem with recording screen creep and bag a bigfoot. Voice clips 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.

82f9056988 Dual core support for PP502x players (iPod G4 and later, iriver h10, Sansa - 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.

8a82892e52 Thread API enhancements. 
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.

0f5cb94aa4 Big Patch adds primarily: Samplerate and format selection to recording for 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.

a85044bf9e New scheduler, with priorities for swcodec platforms. Frequent task 
switching should be more efficient and tasks are stored in linked
lists to eliminate unnecessary task switching to improve performance.
Audio should no longer skip on swcodec targets caused by too CPU
hungry UI thread or background threads.

abd9f83e92 Two new sections for IRAM usage: .irodata (selectable with the ICONST_ATTR attribute macro), allowing to put 'const' data into IRAM without causing a section type conflict, and .ibss (selectable with the IBSS_ATTR attribute macro) for uninitialised data. * Rockbox core: Adjusted the linker scripts and init code to not include the .ibss section in the binary, it is cleared instead. Saves ~500 bytes on archos and ~30KB on iriver. Codecs and plugins don't handle .ibss in a special way yet. * The init code properly handles empty sections now (except .stack, which should never be empty). * Unified the init code for SH1 and coldfire a bit.
