rockbox/uisimulator/sdl/kernel.c, branch master My Rockbox tree Add a complete priority inheritance implementation to the scheduler (all mutex ownership and queue_send calls are inheritable). Priorities are differential so that dispatch depends on the runnable range of priorities. Codec priority can therefore be raised in small steps (pcmbuf updated to enable). Simplify the kernel functions to ease implementation and use the same kernel.c for both sim and target (I'm tired of maintaining two ;_). 1) Not sure if a minor audio break at first buffering issue will exist on large-sector disks (the main mutex speed issue was genuinely resolved earlier). At this point it's best dealt with at the buffering level. It seems a larger filechunk could be used again. 2) Perhaps 64-bit sims will have some minor issues (finicky) but a backroll of the code of concern there is a 5-minute job. All kernel objects become incompatible so a full rebuild and update is needed. 2008-03-25T02:34:12+00:00 Michael Sevakis jethead71@rockbox.org 2008-03-25T02:34:12+00:00 27cf67733936abd75fcb1f8da765977cd75906ee git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16791 a1c6a512-1295-4272-9138-f99709370657

Do some simplification in switch_thread regarding interrupt enabling which simplifies kernel objects as well. Simply doing unconditional disable/enable should be fine in the firmware. Not sure about the case in the bootloader for all targets and so will evaluate but that should be fine too if everything is masked. 2008-01-19T13:27:47+00:00 Michael Sevakis jethead71@rockbox.org 2008-01-19T13:27:47+00:00 32a531b09bf05000048bb3e1cbc25556075e2334 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16107 a1c6a512-1295-4272-9138-f99709370657

Finally, out goes struct spinlock for anything but mutiprocessor targets where it becomes a reenterable corelock. 2008-01-18T13:12:33+00:00 Michael Sevakis jethead71@rockbox.org 2008-01-18T13:12:33+00:00 6a8379674c43103c008f841968b84287b8fdaf89 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16105 a1c6a512-1295-4272-9138-f99709370657

Add queue_peek to the kernel (written by Mike Sevakis), and use it to improve upon my previous commit. 2007-10-27T18:08:18+00:00 Nicolas Pennequin nicolas.pennequin@free.fr 2007-10-27T18:08:18+00:00 1839edf64ad0a4b6d96a5dd5ce24ab8075954dc6 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15336 a1c6a512-1295-4272-9138-f99709370657

Implement as genuine a set_irq_level function for the sim as possible. The yield added earlier is still nescessary since other threads won't run anyway while viewing the database screen on either sim or target. 2007-10-26T23:11:18+00:00 Michael Sevakis jethead71@rockbox.org 2007-10-26T23:11:18+00:00 d6af28739747099f98f541d1b76ba501882e113c git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15321 a1c6a512-1295-4272-9138-f99709370657

Finally full multicore support for PortalPlayer 502x targets with an eye 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. 2007-10-16T01:25:17+00:00 Michael Sevakis jethead71@rockbox.org 2007-10-16T01:25:17+00:00 a9b2fb5ee3114fe835f6515b6aeae7454f66d821 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15134 a1c6a512-1295-4272-9138-f99709370657
