This implements memory transaction support for: * Intel Restricted Transactional Memory (RTM), also known as TSX-NI (Transactional Synchronization Extensions New Instructions) * POWER v2.09 Hardware Trace Monitor (HTM) on GNU/Linux transactional_lock_guard, transactional_shared_lock_guard: RAII lock guards that try to elide the lock acquisition when transactional memory is available. buf_pool.page_hash: Try to elide latches whenever feasible. Related to the InnoDB change buffer and ROW_FORMAT=COMPRESSED tables, this is not always possible. In buf_page_get_low(), memory transactions only work reasonably well for validating a guessed block address. TMLockGuard, TMLockTrxGuard, TMLockMutexGuard: RAII lock guards that try to elide lock_sys.latch and related latches. |
