I found a missing new line in xboxkrnl_video and corrected it. I also found the name of an unknown function in xam table. Here is my source for it. https://pastebin.com/NbpVq9jG
Proper handling of nans for VMX max/min on x64 (minps/maxps has special behavior depending on the operand order that vmx does not have for vminfp/vmaxfp)
Add extremely unintrusive guest code profiler utilizing KUSER_SHARED systemtime. This profiler is disabled on platforms other than windows, and on windows is disabled by default by a cvar
Repurpose GUEST_SCRATCH64 stack offset to instead be for storing guest function profile times, define GUEST_SCRATCH as 0 instead, since thats already meant to be a scratch area
Fix xenia silently closing on config errors/other fatal errors by setting has_console_attached_'s default to false
Add alternative code path for guest clock that uses kusershared systemtime instead of QueryPerformanceCounter. This is way faster and I have tested it and found it to be working, but i have disabled it because i do not know how well it works on wine or on processors other than mine
Significantly reduce log spam by setting XELOGAPU and XELOGGPU to be LogLevel::Debug
Changed some LOGI to LOGD in places to reduce log spam
Mark VdSwap as kHighFrequency, it was spamming up logs
Make logging calls less intrusive for the caller by forcing the test of log level inline and moving the format/AppendLogLine stuff to an outlined cold function
Add swcache namespace for software cache operations like prefetches, streaming stores and streaming loads.
Add XE_MSVC_REORDER_BARRIER for preventing msvc from propagating a value too close to its store or from its load
Add xe_unlikely_mutex for locks we know have very little contention
add XE_HOST_CACHE_LINE_SIZE and XE_RESTRICT to platform.h
Microoptimization: Changed most uses of size_t to ring_size_t in RingBuffer, this reduces the size of the inlined ringbuffer operations slightly by eliminating rex prefixes, depending on register allocation
Add BeginPrefetchedRead to ringbuffer, which prefetches the second range if there is one according to the provided PrefetchTag
added inline_loadclock cvar, which will directly use the value of the guest clock from clock.cc in jitted guest code. off by default
change uses of GUEST_SCRATCH64 to GUEST_SCRATCH
Add fast vectorized xenos_half_to_float/xenos_float_to_half (currently resides in x64_seq_vector, move to gpu code maybe at some point)
Add fast x64 codegen for PackFloat16_4/UnpackFloat16_4. Same code can be used for Float16_2 in future commit. This should speed up some games that use these functions heavily
Remove cvar for toggling old float16 behavior
Add VRSAVE register, support mfspr/mtspr vrsave
Add cvar for toggling off codegen for trap instructions and set it to true by default.
Add specialized methods to CommandProcessor: WriteRegistersFromMem, WriteRegisterRangeFromRing, and WriteOneRegisterFromRing. These reduce the overall cost of WriteRegister
Use a fixed size vmem vector for upload ranges, realloc/memsetting on resize in the inner loop of requestranges was showing up on the profiler (the search in requestranges itself needs work)
Rename fixed_vmem_vector to better fit xenia's naming convention
Only log unknown register writes in WriteRegister if DEBUG :/. We're stuck on MSVC with c++17 so we have no way of influencing the branch ordering for that function without profile guided optimization
Remove binding stride assert in shader_translator.cc, triangle told me its leftover ogl stuff
Mark xe::FatalError as noreturn
If a controller is not connected, delay by 1.1 seconds before checking if it has been reconnected. Asking Xinput about a controller slot that is unused is extremely slow, and XinputGetState/SetState were taking up
an enormous amount of time in profiles. this may have caused a bit of input lag
Protect accesses to input_system with a lock
Add proper handling for user_index>= 4 in XamInputGetState/SetState, properly return zeroed state in GetState
Add missing argument to NtQueryVirtualMemory_entry
Fixed RtlCompareMemoryUlong_entry, it actually does not care if the source is misaligned, and for length it aligns down
Fixed RtlUpperChar and RtlLowerChar, added a table that has their correct return values precomputed
C++17ification!
- Filesystem interaction now uses std::filesystem::path.
- Usage of const char*, std::string have been changed to
std::string_view where appropriate.
- Usage of printf-style functions changed to use fmt.
- Convert http to https, provide archive link when possible.
- Made CPU-JIT.png more readable on dark themes;
Added a white background so there isn't black text on a black
background.
- [GPU] Precalculate memory byte usage for base mip (and any additional mip levels).
- [GPU] Change TextureCache::WatchCallback so that if it's fired multiple times for the same texture it does not assert.
- [GPU] Add write watches for texture memory associated with additional mipmap levels.
