rockbox/firmware/asm/thread-unix.c, branch master My Rockbox tree thread-unix patchup! 2014-08-18T14:40:44+00:00 Michael Sevakis jethead71@rockbox.org 2014-08-18T13:44:55+00:00 a9713d89e76158c6b7be4d8873a921e30efe688f The changed thread code may not wish to save the old context under certain circumstances but thread-unix.c assumed it would, cached it and used it unconditionally. Also, prevent it from leaking away all the jump buffers (old problem). Creating and removing threads would eventually run it out of buffers and then it would crash after that. Plugins, like Pictureflow, which have worker threads could only be started a few times. Implement a simple O(1) allocator that will reuse them and stays self-contained to its own types (as it appears the original author intended). Change-Id: Icf65413c086b346fb79bf827102b725269e2812c

Create fimrware/asm directory for assembly optimized stuff. 2012-01-22T17:46:44+00:00 Thomas Martitz kugel@rockbox.org 2012-01-04T17:07:21+00:00 991ae1e39553172a7dd6cd8c634aebfce892e261 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
