2007-03-23In reponse to a report of a blocking violation, give sync queues a going ↵Michael Sevakis
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
2007-03-21Update sync queues to use a statically allocated return value in order to ↵Michael Sevakis
facilitate upcoming COP updates. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12881 a1c6a512-1295-4272-9138-f99709370657
2007-03-12Disable bootloader messages in the H10 and Sansa bootloaders unless the PLAY ↵Barry Wardell
(on H10) or RIGHT (on Sansa) button is being held. Messages are still displayed if an error occurs. 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
2007-03-11Optimized the gui list code performance, including automatic frame dropping ↵Miika Pekkarinen
and cpu boosting when button events are getting queued. Improved scrollwheel acceleration code is needed to notice a real change. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12721 a1c6a512-1295-4272-9138-f99709370657
2007-03-09Put an end to priority inversion in the ata driver. Gave up trying to have ↵Michael Sevakis
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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12688 a1c6a512-1295-4272-9138-f99709370657
2007-03-04Dual core support for PP502x players (iPod G4 and later, iriver h10, Sansa - ↵Daniel Ankers
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

2006-11-11Thread API enhancements.Brandon Low
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

2006-09-16New scheduler, with priorities for swcodec platforms. Frequent taskMiika Pekkarinen
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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@10958 a1c6a512-1295-4272-9138-f99709370657

2005-10-03Coldfire: New timer handling on CPU frequency change, adjusting the ↵Jens Arnold
prescaler on the fly, for both tick and user timer. Precondition is that the higher frequencies are integer multiples of the base: now NORMAL is 45 MHz and MAX is 124 MHz. Removes the need for applications with longer timer periods (>= 10 ms) to boost the CPU all the time, e.g. the grayscale lib. Timer counts are now always based on the base frequency (CPU_FREQ). * Adjusted the RAM refresh timers to the new frequencies (all frequencies for H100) * All: Fixed the tick timer count being off by one. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7576 a1c6a512-1295-4272-9138-f99709370657
