musl - musl - an implementation of the standard library for Linux-based systems

Age	Commit message (Collapse)	Author	Lines
2016-03-02	add sched_getcpu vDSO support	Nathan Zadoks	-0/+31
	This brings the call to an actually usable speed. Quick unscientific benchmark: 14ns : 102ns :: vDSO : syscall
2016-03-02	add sched_getcpu	Nathan Zadoks	-0/+13
	This is a GNU extension, but a fairly minor one, for a system call that otherwise has no libc wrapper.
2014-12-02	fix return value of pthread_getaffinity_np and pthread_setaffinity_np	Rich Felker	-8/+11
	these functions are expected to return an error code rather than setting errno and returning -1.
2014-12-02	fix uninitialized output from sched_getaffinity	Rich Felker	-1/+5
	the sched_getaffinity syscall only fills a cpu set up to the set size used/supported by the kernel. the rest is left untouched and userspace is responsible for zero-filling it based on the return value of the syscall.
2014-05-04	remove useless __yield alias for sched_yield	Rich Felker	-4/+1
	this is no longer used for anything, and reportedly clashed with a builtin on certain compilers.
2013-08-10	add pthread_setaffinity_np and pthread_getaffinity_np functions	Rich Felker	-18/+26

2013-08-10	add cpu affinity interfaces	Rich Felker	-0/+29
	this first commit just includes the CPU_* and sched_* interfaces, not the pthread_* interfaces, which may be added later. simple sanity-check testing has been done for the basic interfaces, but most of the macros have not yet been tested.
2012-11-11	add support for thread scheduling (POSIX TPS option)	Rich Felker	-9/+11
	linux's sched_* syscalls actually implement the TPS (thread scheduling) functionality, not the PS (process scheduling) functionality which the sched_* functions are supposed to have. omitting support for the PS option (and having the sched_* interfaces fail with ENOSYS rather than omitting them, since some broken software assumes they exist) seems to be the only conforming way to do this on linux.
2012-05-03	avoid setting nondefault scheduler too	Rich Felker	-1/+1

2012-05-03	implement stub versions of sched_*	Rich Felker	-0/+59
	these actually work, but for now they prohibit actually setting priority levels and report min/max priority as 0.
