Mapping the full buffer is killer on Vtune (either crash or requires a huge processing time).
Instead keep the same ID for code in the same buffers.
I think all buffers are correctly mapped now but I still miss the frame pointer
for VU code.
Cons:
* requires ~180MB of physical memory (virtual memory is the same so it
doesn't impact the 4GB limit)
From steam: 98.81% got at least 2GB of RAM. 83.62% got at least 4GB of RAM.
That being said, it might not really increase RAM requirements as OS could put the
new allocation in the swap.
Pro:
* code is much easier
* remove at least half of the signal listener
* last but not least, it is way easier for profiler/debugger
Doesn't fully work yet
* Unknown stack frame
* Outside any known module
Potential root cause:
* Nvidia driver
* VU code as ebp is required for emulation so likely no frame
* 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
The TLS buffers used by the FastFormatUnicode and FastFormatAscii
classes seem to be responsible for PCSX2 not terminating properly on
Windows under certain conditions (using MTVU before commit
1111e03901, using CDVDgigaherz without a
disc, possibly other conditions).
When PCSX2 shut downs and the FastFormatBuffers are being cleaned up,
the call to pthread_key_delete() would end up calling
WaitForSingleObject(e, INFINITE) and waiting indefinitely for an event
to trigger. It never does get triggered (for reasons unknown) and
therefore PCSX2 doesn't terminate properly.
Remove the usage of TLS buffers in the FastFormatString classes - it
fixes the termination issue on Windows and doesn't seem to have much
effect on performance.
Buttons done, configuration initialization done.
Still need to add Gamepad and Joysticks configuration frames.
Require png file for the moment (the embedded picture will be fixed after).
New Onepad GUI based on wxWidget (Main frame almost finish)
Background picture is now embedded
Button binding works
Loading and saving works
Need to add feedback and gamepad, joysticks configuration frame
Modification of the onepad CMakeList.txt
Automatic generation of images headers using perl script
Modification of the test feedback function
Basically it creates a /tmp/perf-`pid`.map file which will contains
a mapping of the x86 code with the EE/IOP/VU code
* You need to enable the profiler with a define
* You can split the profiling by block (inside a recomp buffer)
v2: add new file to VS xml files
v3: remove useless include
Let's the kernel manage the memory either with builtin lazy allocation or
swapped memory.
Avoid to handle SIGSEGV manually (nicer for debug) and removes 250 lines of code.
