Nekotekina f0cba1371c vm: adjustments 
Increase max range lock size (less than 512 MiB)
Remove "range_executable" flag, make it reserved.

Eladash fefab50e06 Fix vm::range_lock, imporve vm::check_addr 2020-11-11 10:30:09 +03:00
Nekotekina 8bc9868c1f SPU/vm: Improve vm::range_lock a bit 
Use some prefetching
Use optimistic locking
 2020-11-08 17:23:17 +03:00
Nekotekina 3507cd0a37 SPU: improve spu_thread::reservation_check 
Use optimistic locking and optimistic loop (expecting 1 iteration).

Nekotekina 21ec32b465 vm: implement g_shmem for range locks 
Renamed from g_shareable. Contains pointers instead of bits.
Used in range locks to prevent any "collision" between memory.

Nekotekina b68bdafadc vm: refactor vm::range_lock again 
Move bits to the highest, set RWX order.
Use only one reserved value (W = locked).
Assume lock size 128 for range_locked.
Add new "Size" template argument that replaces normal argument.

Eladash 6dcd482dd0 SPU reservations: Do not illegally dereference reservation data 2020-11-07 14:03:09 +03:00
Nekotekina ba5ed5f380 Fix vm::lock_range wrong check 
Minor header refactoring.

Nekotekina 5d7acda80e vm: minor refactoring 
Renamed internal main range locking method.

Nekotekina 06ecc2ae68 vm::range_lock cleanup and minor optimization 
Removed unused arg.
Linearized some branches.

Nekotekina 46d3066c62 Optimize vm::range_lock 
Only test address on `range_locked`
Don't check current transaction
Remove vm::clear_range_locks completely

Nekotekina ca57f25f26 Fix vm::page_protect and range flags 
Should fix assertion in vm.cpp
Minor refactoring of internal locking

Nekotekina 78c986b5dd Improve vm::range_lock 
Not sure how it ever worked
Clear redundant vm::clear_range_lock usage

Nekotekina 80530e8aef vm: rename g_addr_lock to g_range_lock 
Reduce size to 29 bits and use 3 bits to communicate some information.
This information can be used to to a very cheap lock-free access tests.
 2020-10-31 15:08:49 +03:00
Nekotekina 3419d15878 vm: add extern clear_range_locks function 
Allows to wait for range locks to clear for specified range.
vm::range_lock now monitors specified reservation lock as well.
 2020-10-30 07:58:16 +03:00
Nekotekina 86785dffa4 SPU: make vm::check_addr checks safe under vm::range_lock 
Reuse some internal locking mechanisms.
Also fix vm::range_lock missing check.

Nekotekina 4966f6de73 vm: improve range_lock and shareable cache (Non-TSX) 
Allocate "personal" range lock variable for each spu_thread.
Switch from reservation_lock to range lock for all stores.
Detect actual memory mirrors in shareable cache setup logic.

Nekotekina c7fe8567b8 Experimental squashing of reservation memory area. 
Enables trivial synchronization between shared mem.
Reduces memory usage, but potentially degrades performance.
Rename an overload of vm::passive_lock to vm::range_lock.

Lassi Hämäläinen 499035512b Split Emu/Memory into more logical headers 
- Add vm_locking.h and vm_reservation.h and move relevant functions
  and types to these headers.
- Change include order and make vm_ptr.h, vm_var.h and vm_ref.h headers
  usable invidually and them including vm.h instead of other way around
- Because usage of vm::ptr now requires including vm_ptr.h instead of
  vm.h updated multiple #includes
- Added additional #includes to vm_reservation.h and vm_locking to
  where vm::reservation_* and locking related functions are used
