* Add CPU mode asserts to kernel on blocking functions.Michael Sevakis2017-01-21
| | | | | | | | | This scourge finds it's way back in far too often. Right now, only defined for ARM. Have fun! Change-Id: Ib21be09ebf71dec10dc652a7a664779251f49644
* Create fimrware/asm directory for assembly optimized stuff.Thomas Martitz2012-01-22
| | | | | | | | | | | | | | | | This dir is suitable for stuff that doesn't fit the target tree, e.g. because it also builds on hosted or otherwise. It also has a generic subfolder for fallback C implementations so that not all archs need to provide asm files. SOURCES should only contain "foo.c" where foo.c includes the specific <arch>/foo.c files from the subdirs using the preprocessor. This way automatic selection of asm versions or generic C verion is possible. For the start, the thread support files are moved, since ASM threads can be used on hosted platforms as well. Since core_sleep() remains platform specific it's moved to the corresponding system.h headers. Change-Id: Iebff272f3407a6eaafeb7656ceb0ae9eca3f7cb9
* AS3525v1/2: Enable nested handling of interruptsMichael Sevakis2012-01-08
| | | | | | | | | | | | | | | | | | | | Mostly for the sake of reducing latency for audio servicing where other service routines can take a long time to complete, leading to occasional drops of a few samples, especially in recording, where they are fairly frequent. One mystery that remains is GPIOA IRQ being interrupted causes strange undefined instruction exceptions, most easily produced on my Fuze V2 with a scrollwheel. Making GPIOA the top ISR for now, thus not interruptible, cures it. SVC mode is used during the actual calls. Hopefully the SVC stack size is sufficient. Prologue and epilogue code only uses the IRQ stack and is large enough. Any routine code that should not be interrupted should disable IRQ itself from here on in. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31642 a1c6a512-1295-4272-9138-f99709370657
* Merge functionality of wakeups and semaphores-- fewer APIs and object types. ↵Michael Sevakis2011-03-02
| | | | | | semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29492 a1c6a512-1295-4272-9138-f99709370657
