Nekotekina	050c3e1d6b	Rewrite cpu_thread::suspend_all Now it's a function of higher order. Make only one thread do the hard work of thread pausing.	2020-10-10 13:58:48 +03:00

Nekotekina	090c71aa7c	TSX: Improve cpu_thread::suspend_all implementation Implement low_lock and vip_lock (for shared_mutex). Try to simplify suspend_all implementation with updated shared_mutex.	2019-07-24 17:25:52 +03:00
Nekotekina	e064b92058	mutex.h: fix warning (unary minus unsigned)	2019-04-13 22:56:11 +03:00
Nekotekina	f50d9cc136	Initial support for HLE in internal API atomic_storage<>: add compare_exchange_hle_acq and fetch_add_hle_rel shared_mutex: add methods (un)lock_hle and (un)lock_shared_hle Clang: 👅	2019-01-29 04:33:59 +03:00
Nekotekina	6a30d5a6c1	shared_mutex: increase max_readers to 16383 Standard requires at least 10000 for SharedMutex concept	2018-11-09 16:19:59 +03:00

Nekotekina	9e5b633779	shared_mutex cleanup Rewrite to use unsigned arithmetic, shrink to u32 Ensure zero default unlocked state (will need it later) Inline all public methods, rewrite lock_upgrade() Remove try_lock_degrade(), lock_degrade() methods Implement lock_downgrade() (now trivial) Remove is_reading(), added is_free() Added reader_lock::try_upgrade()	2018-09-27 12:16:43 +03:00
Nekotekina	445e5def42	Remove safe_reader_lock, safe_writer_lock It worked as a simple recursive locker for shared_mutex But its design is flawed and thus can't be fully implemented	2018-09-15 17:09:56 +03:00
Nekotekina	ca5158a03e	Cleanup semaphore<> (sema.h) and mutex.h (shared_mutex) Remove semaphore_lock and writer_lock classes, replace with std::lock_guard Change semaphore<> interface to Lockable (+ exotic try_unlock method)	2018-09-03 23:00:36 +03:00
