Previously, the height of the frame offset was also considered for the total height of the texture which was obviously wrong as the portion before the offset value isn't part of the frame memory.
In the previous code, the threads were created and destroyed in the base
class constructor and destructor, so the threads could potentially be
active while the object is in a partially constructed or destroyed state.
The thread however, relies on a virtual function to process the queue
items, and the vtable might not be in the desired state when the object
is partially constructed or destroyed.
This probably only matters during object destruction - no items are in
the queue during object construction so the virtual function won't be
called, but items may still be queued up when the destructor is called,
so the virtual function can be called. It wasn't an issue because all
uses of the thread explicitly waited for the queues to be empty before
invoking the destructor.
Adjust the constructor to take a std::function parameter, which the
thread will use instead to process queue items, and avoid inheriting
from the GSJobQueue class. This will also eliminate the need to
explicitly wait for all jobs to finish (unless there are other external
factors, of course), which would probably make future code safer.
The previous implementation of HPO adds an offset on vertex position. It
doesn't always work beside it moves the rendering window.
The new implementation will add a texture offset so that instead to sample
the middle of the GS texel, we will sample the middle of the real texture texel.
It must be manually enabled with
* UserHacks_HalfPixelOffset_New = 1 (keep a small offset as intended by GS effect)
* UserHacks_HalfPixelOffset_New = 2 (no offset)
v2: always apply a 0.5 offset in case of float coordinates (Tales of Abyss)
Might break other games but few of them uses float coordinates to read
back the target
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
* Use POD type to avoid SSE/AVX compilation dependency
* global object to reduce cache miss
* dynamically object so give a chance to allocate below 2GB (allow x64
optimization)
Fixes Coverity CID 127721: Program hangs
Change the sleep to a condition variable wait, which has the added
benefit of allowing the plugin to close ever so slightly faster if
there's no disc in the drive.
tex address is a3
vm address is a1
Could help to avoid REX prefix
Reduce prologue/epilogue register copy
Byte code size 41893 => 38912 (on my testcase)
* bin2hex.h is removed
* vptest/vpblendvb YMM support integrated upsteam
* better support of rip for 64 bits
* AVX512 support (only miss the CPU now)
Local change: add BSD3 clause
It will requires a generic (register naming) linear interpolation to use it properly
Gather instruction requires an extra mask register therefore all registers name will be shuffled
Perf wise, initial haswell implementation seems to be microcode emulated.
