Nekotekina	8886414013	Use atomic wait in shared_mutex and semaphore	2019-07-29 03:04:55 +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	96cabeadff	Rewrite condition variables ... Implement helper functions balanced_wait_until and balanced_awaken They include new path for Windows 8.1+ (WaitOnAddress) shared_mutex, cond_variable, cond_one, cond_x16 modified to use it Added helper function utils::popcnt16 Replace most semaphore<> with shared_mutex	2018-11-29 01:30:05 +03:00
Nekotekina	6104685ad6	Implement cond_one sync primitive ... Change futex() args to use unsigned int	2018-11-05 13:14:11 +03:00
Nekotekina	7a024f3355	Implement shared_mutex::lock_unlock ... Minor fix for shared_mutex::try_lock - don't optimize for pessimistic case	2018-10-02 02:22:26 +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	fb5cdf9769	atomic_t<>: extend fetch_op to support cancellation ... Use std::invoke inside atomic_op/fetch_op Remove op_fetch because it's easily replaced Add fetch_dec_sat algorithm (conditional decrement)	2018-09-08 00:32:04 +03:00
Nekotekina	7f542a5c99	Fix safe_writer_lock (typo)	2018-03-11 19:33:01 +03:00
