Bananymous fb61cab70d LibC: Rewrite pthread_mutex using a futex 2025-08-21 02:52:49 +03:00
Bananymous eb7922ab88 LibC: Implement pthread_cond_* using a futex 2025-08-05 03:09:24 +03:00
Bananymous 658a001d91 LibC: Make pthread_barrier safe 
It used to deadlock and it was not safe if more threads than the target
were attempting to wait on it.

Bananymous 57c9f5a8a8 LibC: lock mutex when pthread_cond_timedwait times out 2025-08-05 03:09:24 +03:00
Bananymous d25a5034db LibC: Update thread id on fork 2025-08-05 03:09:24 +03:00
Bananymous f197d39aaf LibC: Don't allow pthread_join to return EINTR 2025-08-05 03:09:24 +03:00
Bananymous 4a95343936 LibC: Make _get_uthread a macro 
This allows nice inlining :)

Bananymous 4e705a91af LibC: Fix pthread keys 
I had misunderstood how these are supposed to work :D
 2025-08-05 03:09:24 +03:00
Bananymous 0f2c02fb04 LibC: Add stubs for pthread_{get,set}schedparam 2025-06-28 16:55:13 +03:00
Bananymous f9451915b9 LibC: Use `pause` in pthread spinlock locking 2025-06-16 15:07:58 +03:00
Bananymous 5ad7d7edb1 DynamicLoader: Fix TLS on 32 bit platform 
There were two problems with my previous implementation
- TLS was not allocated if nothing used it. There is a fallback
  initialization in _init_libc, but this was not enough if one of the
  init functions tried to access errno.
- __tls_get_addr was not resolved. If __tls_get_addr was called through
  a plt entry, everything would just break :(

Bananymous df7f245cf8 LibC: Implement pthread_atfork 
Again this code is not tested but *feels* right :D
 2025-06-01 13:48:03 +03:00
Bananymous dbdefa0f4a LibC: Implement pthread cancelation 
This code is not tested at all but it looks correct xD
 2025-06-01 13:48:03 +03:00
Bananymous c957f1ddca LibC: Cleanup pthread code and add some pthread_attr functions 
errno, pthread cleanup and pthread id are now stored in uthread. This
allows using these without TLS
 2025-06-01 13:48:03 +03:00
Bananymous b774f147da LibC: Implement dummy pthread_attr_{get,set}detachstate 
detached threads are not yet supported, but this allows implementation
to make sure threads are joinable.
 2025-04-21 19:58:01 +03:00
Bananymous 2a5921b9c9 LibC: Implement pthread_barrier 
This is not fully working but should be fine for most cases
 2025-04-21 19:53:38 +03:00
Bananymous 60cb392e97 LibC: Implement pthread_barrier 
This is yet another bad sched_yield implementation :D
 2025-04-21 19:52:14 +03:00
Bananymous 1c88d0d7f7 LibC: Implement pthread_rwlock 
This uses the same dumb sched_yield instead of actually blocking :D
 2025-04-21 18:48:47 +03:00
Bananymous 5d8dd090a9 LibC: Implement `pthread_once` 2025-04-21 14:17:17 +03:00
Bananymous 265b4c2b22 LibC: Implement `thread_equal` 2025-04-20 03:27:16 +03:00
Bananymous db9db2cc40 LibC: Implement basic pthread mutexes 
This implementation is just calling sched_yield if it could not get
mutex. This is not optimal as it does not allow the CPU to idle, but it
works for now :)

Also I did not test this code at all, but it feels correct :D

Bananymous 3642eabac0 LibC: Use BAN::atomic_* functions in pthread spinlock 
This allows us not to reinterpret_cast pthread_spin_t to
BAN::Atomic<pthread_spin_t> which is much better :)

Bananymous 1ccff9478f LibC: Don't define __tls_get_addr if TLS is disabled 
This makes linking fail if something tries to use TLS :)
 2025-04-20 03:11:41 +03:00
Bananymous 85f9b585f5 LibC: Don't yield on `pthread_spin_lock` 
Thats kinda the whole point of spinlocks :D

Bananymous 01626b4c9f LibC: Add stub for `pthread_detach` 2025-04-20 03:11:41 +03:00

Bananymous ac90800c3c Kernel/LibC/DynamicLoader: Implement thread local storage 
For some reason this does not work on 32 bit version, so it is disabled
on that platform. I'll have to look into it later to find the bug :)
