Nekotekina badb3dc2dd atomic.cpp/threads: remove old wait callback
Add new wait callback which simply collects statistics.
Shift workarounds towards actual problem detection.

Nekotekina 5b69eda39a Fix suspend_all bug (TSX, TSX-FA)
Could cause freezes.
2020-11-14 10:56:05 +03:00
Nekotekina ab365fe494 Fixed thread pool a bit
Use 128-bit allocator instead of queue.
When pool is full (128), threads just terminate as before.

Nekotekina cdaa8cb5c4 CPU: Improve suspend_all g_suspend_counter handling
Increase in two stages, giving more chances to use it.
Second stage is when all wait flags have been seen.

Nekotekina 557f0c5a8a atomic.cpp: remove load() from notify functions
Only compare masks for overlap for second overload (with mask provided).
Explicit "new value" can be provided in new 3-arg overloads.
Also rename atomic_storage_futex -> atomic_wait_engine.
2020-11-06 04:44:31 +03:00

Nekotekina dea8aa675a Optimize cpu check_state() a bit
Move cpu_flag::dbg_pause check from the start.
To the moment before it actually goes to sleep.

Nekotekina 86fc842c89 TSX: new fallback method (time-based)
Basically, using timestamp counter.
Rewritten vm::reservation_op with the same principle.
Rewritten another transaction helper.
Add two new settings for configuring fallbacks.
Two limits are specified in nanoseconds (first and second).
Fix PUTLLC reload logic (prevent reusing garbage).
2020-10-31 15:34:14 +03:00
Nekotekina ba26e16411 Rename vm::reservation_light_op -> light_op
Rename vm::reservation_peek_op -> peek_op
Also remove overkill assertion for cpu_flag::temp.

Nekotekina f972fa26a4 Derive RSX Replay thread from cpu_thread
Its id is set to 0, so fix some id_type() usages.
2020-10-30 17:36:11 +03:00
Nekotekina 150e18539c Allow cpu_thread& arg passed to the syscalls
Minor cleanup. cpu_mem(), cpu_unmem() removed.
2020-10-30 17:03:32 +03:00
Nekotekina 0da24f21d6 CPU: improve cpu_thread::suspend_all for cache efficiency (TSX)
Add prefetch hint list parameter.
Workloads may be executed by another thread on another CPU core.
It means they may benefit from directly prefetching the data as hinted.
Also implement mov_rdata_nt, for "streaming" data from such workloads.

Nekotekina d6daa0d05b Fix cpu_flag::temp, make sure it removes cpu_flag::wait 2020-10-28 14:00:09 +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.
2020-10-27 17:56:19 +03:00
Nekotekina f1e66085cd Fixup for cpu_flag::temp
Wrong check_state() result was triggering assertion.
2020-10-26 01:18:26 +03:00
Nekotekina 130a0ef20e Implement cpu_flag::temp flag
Accompanies wait flag, indicating that it was set in limited conditions.
Such condition don't allow thread to terminate after its removal.
