Stenzek 7c9c8e197c Common: Replace MemsetFast routines with C memset 
And associated cleanup.

On most compilers these days, it'll either inline the memset with vector
fills or rep stosq, or outline with a call to memset.

I trust the compiler is probably going to make a better decision here,
than manual SSE intrinsics.

Ends up a couple of percent faster in FMV decoding.

Connor McLaughlin 00bcb4cf02 System: Revamp memory allocation 
Guest memory is now mapped into a shared memory/file mapping, for use
with fastmem.

64-bit and 128-bit arguments are passed by register/value instead of by
reference/address.

LDL/LDR/SDL/SDR now use 64-bit GPRs instead of SSE.

Gregory Hainaut 2ff43f2ed8 core: remove throw specifier on destructor 
It is the 'default' on C++11

Gregory Hainaut 44b5552231 MTVU: hide ring buffer pointer bug under the carpet 
There is a bug lurking around (intro of SotC). Unfortunately, I didn't find it. So instead, I added a safety net
in the ring buffer reservation.

Gregory Hainaut e3d1871f86 MTVU: small thread scheduling improvement 
* Use yield to avoid a spin loop during WAIT
* Don't flush the full buffer when we miss space

Gregory Hainaut fff5230631 MTVU: redo properly atomic management around the MTVU ring buffer 
The ring buffer is composed of severals read/write by transaction.

Atomic operations are only required at the start/end of the full
transaction. In the middle, you can use normal variable (optimization
opportunity for the compiler)

Use acquire/release semantics on isBusy and vuCycles to remain 100% safe
(relaxed might be doable but better be safe than sorry)

Use dedicated cache line for atomic variable to avoid any conflict between CPU

Gregory Hainaut 10ea05bc6f common: remove old atomic wrapper 
Use cross-platform std::atomic instead
 2016-07-14 18:29:41 +02:00
Gregory Hainaut 567976e822 MTVU: port vuCycles to std::atomic 
V2: use relaxed order as the variable doesn't carry load/store dependency
It is only used as a counter for the speed hack
 2016-07-14 18:29:41 +02:00
Gregory Hainaut 3f0655c821 MTVU: port write pointer to atomic and optimize atomic access 
Write pointer can be relaxed-read from the EE thread
Read pointer can be relaxed-read from the VU thread

Warning: AtomicExchange calls were replaced by release-store
However AtomicExchange generates a memory barrier (at least on linux)
So either it is useless and it will be faster, or it will explode ;)
 2016-07-14 18:29:41 +02:00
Gregory Hainaut ca46921796 MTVU: use acquire/release semantics for atomic operation 
* Avoid the generation of memory barrier (mfence)
* Based on the fact that it used to work on previous code without any
  barrier

v2:
* keep basic code in reset path
* use relaxed access for isBusy. The variable doesn't carry load/store
  dependency but is instead an hint to optimize semaphore post

refractionpcsx2 0147e6cb8d Vif: Fix for Unpacks when WL = 0. (KH2 + Tests) Removes a long standing hack. 
Note: CL = 0 behaviour is still not completely accurate, the first vector is incorrect, but will look at that another day, need a game that does it first really so we can see if it helps :)

massive failure
