Added an external exception check when the CPU writes to the FIFO. This allows
the CPU time to service FIFO overflows. Fixes random hangs caused by FIFO
overflows and desyncs like in "The Last Story" and "Battalion Wars 2". Thanks
to marcosvitali for the research.
Added some code to unlink invalidated blocks so that the recompiled block can be
linked (speed-up).
This release still fixed the hangs produced by fifo overflow without sacrifice
performance. For example you can test Tutorial moves at the beginning of The last history now
is fluid 30/60.
Fixed possibles random hangs in DC mode.
Fixed hangs in DC mode in (Simpsons, Monkey Island, Pokemon XD, etc)
Implemented accurate management of Pixel Engine Interrupts. Now the GPU loop
is stopped when a PE Interrupt needs to be managed and resumed when Pixel Engine
finish.
Fixed Metroid Prime 3 and 2 desync. And other games with desync because of
FIFO Reset. That happens because FIFO_RW_DISTANCE_HI must be written first, for checking
fifo.CPReadWriteDistance == 0, so some fifo resets was not managed in the right
way.
Fixed Super Monkey Ball in some cases when the game write the
WriteReadDistance need to be safe like the SafeCPRead.
Improved the CheckException for the GatherPipe writes in JIT, now only the
External Exceptions are processed.
Fixed definitely Pokemon XD in dual core mode. This game is doing something
not allowed. It attach to CPU the same fifo attached to the GPU in multibuffer
mode. I added a check to prevent overwrite the GPU FIFO with the CPU FIFO. If
the game do that on breakpoint the solution can fail.
Fixed ReadWriteDistance calc when CPRead > CPWrite.
Added Token and Finish cause to GP Jit checking.
Additional cleanup in CommandProcessor.
Fixes issue 5209
Fixes issue 5055
Fixes issue 4889
Fixes issue 4061
Fixes issue 4010
Fixes issue 3902
For example you can test Tutorial moves at the beginning of The last history now is fluid 30/60.
Shuffle2: I've delete the hacky line, I think is not necessary anymore. Additional some clean in CommandProcessor.
Please test The Last Story and others games affected in the previous commits and give me a feedback.
To use the native code handler, place the kenobiwii.bin file into the Sys directory. Dolphin will silently fall-back to the emulated code handler if the file is not there.
Fixes issue 4561.
Use the clobber list instead of the stack to save rbx when executing the cpuid
instruction with inline assembly. This avoids breaking GCC assumptions about
the stack pointer location.
more specifically: if the emulator stops unexpectedly, it is quite possible that one of the shader cache files will have some bytes near the end that never got their values filled in. this change adds an index number at the end of each entry as extra verification that the entry is valid, so that invalid entries can be ignored (and eventually overwritten) instead of causing crashes.
This should make it so if you try to load an incompatible save, it simply doesn't load, instead of crashing dolphin. (I can't guarantee no crash but it's much less likely now)
The code from 748be364e5 incorrectly accepted -0x100000000 on x86_64.
Also if ERANGE is returned by strtoul(), reject the parsed value regardless
of what that value is. This fixes invalid values being returned when compiling
with Visual C++. Thanks to "cotton" for testing this.
On x86-64, "unsigned long" is 64 bits wide, so it is possible for a number
to not trigger a range error on strtoul() but still not fit inside an u32.
An extra check is added to ensure that 32-bit and 64-bit builds will accept
the same numbers.
Passing MAP_FIXED to mmap causes already mapped pages in the requested
region to be replaced. On Mac OS X this caused pages for JIT-generatd
code to appear in the memory range previously auto-allocated for the RAM
of the emulated machine. This led to a hang at boot time. The same problem
can probably occur on FreeBSD, but not on Linux since MAP_32BIT is used
there instead of MAP_FIXED.
The solution is to not use MAP_FIXED, but instead rely on the OS honoring
the hinted address which is below 4 GB: we don't need an exact match,
just a low address.
hopefully this will be the last code change committed directly to master for a while... :/
next is cmake to replace scons on osx hopefully. pointers anyone? (soren?)
