Nekotekina ea5f5aea5f vm: memory locking rewritten
Added vm::lock_sudo method (wrapper for utils::memory_lock).
Put locking outside of vm::g_mutex scope.
Prelock sudo memory for RSX, vm::stack, vm::main.
Prelock sudo memory for shared memory objects.
Don't check for TSX path.

Nekotekina eaf0bbc108 SPU: don't allocate SPU LS in vm::main
Create its own shared memory object.
Use vm::spu to allocate all SPU types.
Use vm::writer_lock for shm::map_critical.

SPU Debugger: Implement float registers view + General debugger fixes (#9265)
* SPU Debugger: Fix try_get_insert_mask_info
* Debugger: Always update thread state on context's data change
No longer needing to press on thread's instructions for actions to work!

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

Nekotekina 3ac819ee70 atomic.cpp: fix waiting on multiple variables
Silly bugs are so silly...

Nekotekina 00f877e812 atomic.cpp: fix rare overload scenario
If slot allocation fails, increase reference counter in every slot.
This prevents search routine from "losing" some slots.

Nekotekina 1e269751bf Temporarily disable memory locking if TSX is not used
It's a very heavy operation that could cause some problem under mutex lock.

Nekotekina 5b69eda39a Fix suspend_all bug (TSX, TSX-FA)
Could cause freezes.

Nekotekina 71ca413067 Don't add lonely cpu_flag::memory on TSX path (bug) 2020-11-14 09:03:33 +03:00
Nekotekina 0c7f9458c0 Fix thread pool resource management.
Make sure no tail call happens (change ret address to a trampoline).
Make sure thread handles don't leak if the pool is full.
2020-11-13 17:17:45 +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 e48f160a29 atomic.cpp: continuation of fixing all-ones masks
Also added missing const noexcept.

Nekotekina cfda4d0ade atomic.cpp: optimize raw_notify() for unspecified pointer mode
Remove unnecessary optimization from cond_alloc().
Optimistic case was absolutely dominating anyway.
Although the whole function is a dirty hack.
Now scanning through all threads is faster.

Nekotekina 70761a4ef0 atomic.cpp: fix notification bug from few commits before
Make sure forced notification ignores mask comparison.
Also fix masks provided by smaller types to correct ones.

Nekotekina e37df998e9 atomic.cpp: minor optimization
Silly MSVC emits unnecessary initialize-on-first-use code guards.
Didn't check other compiler. But workaround just works anyway.
2020-11-12 03:41:19 +03:00
Nekotekina c30cdfb3a7 atomic.cpp: merge more atomic variables for simplicity
Compress 16-bit ref counter and two 48+64 bit slot allocators.
This allowed to remove some weird unnecessary logic paths.
Adjust hashtable size to keep it the same.
2020-11-12 03:39:05 +03:00
Nekotekina 350b704cd7 atomic.cpp: combine two atomics (ref ctr and wait ptr)
Should fit into cache line perfectly.
Also makes ptr check more robust.

Nekotekina ad013d59f4 atomic.cpp: don't load actual memory on empty mask
It's not an optimization. It just allows some tricks safely.
2020-11-11 23:59:09 +03:00
Nekotekina d391133524 atomic.cpp: minor notification improvement
Check mask before locking the reference.
Can help to not bother non-eligible waiters.
2020-11-11 23:51:41 +03:00
Nekotekina 4b823469f7 atomic.cpp: restore notify_all() behaviour
Restore batch notification with non-blocking attempts.
2020-11-11 22:43:13 +03:00
Nekotekina 7cd1e767be atomic.cpp: implement some atomic wait operations.
Instead of plain waiting while equal to some value,
it can be something like less, or greater, or even bitcount.
But it's a draft and untested. Hopefully doesn't break anything.

Nekotekina c047ab6147 atomic.cpp: waitable atomics got brutally rewritten
Hashtable increased and flatten, tree-alike extensions removed.
Some things simplified, so it can actually decrease perf a bit.
But most platforms shouldn't be affected.
Removed limit of 56 waiters per pointer.
Real limit now is about 65535.

Nekotekina d1ee7c651f Make memory locking optional (mlock, VirtualLock).
Fix desired locking operation (to fix "sudo" memory).
It was discovered that some systems have outdated configuration.
With too tight limit, it's almost impossible to lock anything in memory.
2020-11-10 06:05:37 +03:00
Nekotekina dcbe8ef5f4 Import VirtualAlloc2 if available (Win10+)
Import MapViewOfFile3 as well.
Unused, this crap is tricky.
