29a336d6a8 sched/tls: remove PTHREAD_CLEANUP from Kconfig 
use PTHREAD_CLEANUP_STACKSIZE to enable or disable interfaces pthread_cleanup_push() and pthread_cleanup_pop().
reasons:(1)same as TLS_TASK_NELEM (2)it is no need to use two variables

d189a86a35 system: pthread_barrierwait should be moved to kernel space 
The current implementation requires the use of enter_critical_section, so the source code needs to be moved to kernel space

fork isn't supported yet, so the dummy implementation is enough.

9ce03b1660 Move pthread-specific data into TLS 
1. Move pthread-specific data files from sched/pthread/ to libs/libc/pthread.
2. Remove pthread-specific data functions from syscalls.
3. Implement tls_alloc() and tls_free() with system calls.
4. Reimplement pthread_key_create() and pthread_key_free() using tls_alloc() and tls_free().
5. Reimplement pthread_set_specific() and pthread_get_specicif() using tls_set_value() and tls_get_value()

00933cfece sched/sched: Add sched_get_stackinfo() 
The new OS interface, sched_get_stackinfo() combines two pthread-specific interfaces into a single generic interface.  The existing pthread_get_stackaddr_np() and pthread_get_stacksize_np() are moved from sched/pthread to libs/libc/pthread.

There are two motivations for this change:  First, it reduces the number of system calls.  Secondly, it adds a common hook that is going to used for a future implementation of TLS.

b2f110e0b0 include/pthread.h and libs/libc/pthread/pthread_spinlock.c: Add a very preliminary implementation of the new POSIX pthread_spinlock_* interfaces. This feature is marked EXPERIMENTAL. There are usage model issues to be examined and there are also architectural issues that currently limit the implemantion to the FLAT build (that is, however, fixable when the APIs are needed. 2019-02-28 10:21:05 -06:00

0951151c33 libs/libc/pthread, syscall/, and include/sys/syscall.h: Support for pthread_mutex_timedlock() was added recently, however no new system call was added for the API make is usable only in the FLAT build. With a pthread_mutex_timedlock() system call, there is no reason for a pthread_mutex_lock() system call since it is now nothing more than an wrapper around pthread_mutex_timedlock(), passing NULL for the time value. The pthread_mutex_lock() syscall was removed and the pthread_mutex_lock() implemented was moved from /sched/pthread to where it now belows in libs/libc/pthread. 2019-02-25 18:19:13 -06:00

2c93467436 pthreads: Add support static pthread stack. Add standard pthread_attr_setstack() and pthread_attr_getstack(). In all cases where the stack is released, add check to see which allocator must be used to free the stack: The user or the kernel allocator. 2018-08-23 09:49:20 -06:00

cf99fb40c9 This commit moves all of the libraries under a common directory called libs/. This most certainly break libcxx and uClibc++ for now. 
Squashed commit of the following:

    libs/libxx:  Fix some confusing in naming.  If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
    libs/:  Fix paths in moved library directories.
    libs:  Brute force move of libc, libnx, and libxx to libs.  Cannot yet build it in that configuration.
