Nekotekina fd7ea82965 atomic.cpp: fix 3-arg notify functions
Third arg forces comparison with itself, and possibly forced wakeup.
2020-11-07 19:18:14 +03:00
Nekotekina 0bd989b118 atomic.cpp: allow waiting on multiple variables simultaneously
Arbitrary maximum set to 8, but really we need 2, maybe 3.
Added atomic_wait::list object for multi-waiting.
Added atomic_wait::get_unique_tsc just in case.
2020-11-07 18:18:02 +03:00
Nekotekina bd0b292b39 atomic.cpp: adjust assumed pointer mask

Nekotekina 0a5742587a atomic.cpp: upgrade raw_notify()

2020-10-28 03:47:41 +03:00
Nekotekina 6806e3d5c7 atomic.cpp: implement notify callback
Notification can be very heavy, especially if we need to wake many threads.
Callback is set for cpu_thread in order to set wait flag accordingly.

2020-10-24 14:16:32 +03:00
Nekotekina 8628fc441d atomic.cpp: rewrite internals (again)
Use individual semaphore for each thread.
Unfortunately, limit max thread waiting for single address (60).
If limit is reached, use busy waiting.

Nekotekina dc8252bb9f Remove XABORT in PPU/SPU transactions.

Add some minor improvements. Use g_sudo_addr.
