* Finally, out goes struct spinlock for anything but mutiprocessor targets ↵Michael Sevakis2008-01-18
| | | | | | where it becomes a reenterable corelock. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16105 a1c6a512-1295-4272-9138-f99709370657

| | | | | | now but would be with mutex recursion on one used for > 1 core where ownership transfer and cs entry/recursion are allowed to run in parallel (by design). TODO: Add true exchange to wakeup_thread but that's not really important for the time being. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15251 a1c6a512-1295-4272-9138-f99709370657
* Finally full multicore support for PortalPlayer 502x targets with an eye ↵Michael Sevakis2007-10-16
| | | | | | towards the possibility of other types. All SVN targets the low-lag code to speed up blocking operations. Most files are modified here simple due to a name change to actually support a real event object and a param change to create_thread. Add some use of new features but just sit on things for a bit and leave full integration for later. Work will continue on to address size on sensitive targets and simplify things if possible. Any PP target having problems with SWP can easily be changed to sw corelocks with one #define change in config.h though only PP5020 has shown an issue and seems to work without any difficulties. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15134 a1c6a512-1295-4272-9138-f99709370657

* Commit a subset of the dual core changes that have to do with cache ↵Michael Sevakis2007-09-28
| | | | | | handling, stacks, firmware startup and thread startup. Tested on e200, H10-20GB, iPod Color and 5.5G. Thread function return implemented for all targets. Some changes to plugins to follow shortly. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14879 a1c6a512-1295-4272-9138-f99709370657

* Messages queues must be guarded on both ends or else it's a race between ↵Michael Sevakis2007-05-12
| | | | | | 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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13374 a1c6a512-1295-4272-9138-f99709370657
* Simplification, queue pointers don't wrap (except at INT_MAX, but the ↵Jens Arnold2007-04-14
| | | | | | calculation is still correct in this case). Implemented queue_count() for the simulator. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13154 a1c6a512-1295-4272-9138-f99709370657
* Make scheduler functions thread safe core wise. A big step towards playback ↵Miika Pekkarinen2007-03-26
| | | | | | running on COP (not yet possible because more protection on file system level is necessary). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12926 a1c6a512-1295-4272-9138-f99709370657
* 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
* PNX0101 changes:Tomasz Malesinski2007-03-24
| | | | | | | | | | Make PNX0101-specific system.c and crt0.S. Add new register names from LPC2880 user manual. Add support for timer. Enable CPU frequency changing. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12904 a1c6a512-1295-4272-9138-f99709370657
* In reponse to a report of a blocking violation, give sync queues a going ↵Michael Sevakis2007-03-23
| | | | | | over and catch any old, obscure leftover issues. A couple spots needed interrupt stopage where there could be confict if an IRQ post wakes a waiting thread because the queue is overflowing. There does appear to be an issue with wakeup_thread, interrupts and running list modification in general. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12895 a1c6a512-1295-4272-9138-f99709370657

This has already been implemented for iPod bootloaders, but still needs implementing for the other bootloaders. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12742 a1c6a512-1295-4272-9138-f99709370657
* Optimized the gui list code performance, including automatic frame dropping ↵Miika Pekkarinen2007-03-11

* 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.

* 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
