The "close window" keyboard hotkey (Guide-B) now toggles between loglevel -1 and the loglevel set in your config.
Added LoggerBatch class, which accumulates strings into the threads scratch buffer. This is only intended to be used for very high frequency debug logging. if it exhausts the thread buffer, it just silently stops.
Cleaned nearly 8 years of dust off of the pm4 packet disassembler code, now supports all packets that the command processor supports.
Added extremely verbose logging for gpu register writes. This is not compiled in outside of debug builds, requires LogLevel::Debug and log_guest_driven_gpu_register_written_values = true.
Added full logging of all PM4 packets in the cp. This is not compiled in outside of debug builds, requires LogLevel::Debug and disassemble_pm4.
Piggybacked an implementation of guest callstack backtraces using the stackpoints from enable_host_guest_stack_synchronization. If enable_host_guest_stack_synchronization = false, no backtraces can be obtained.
Added log_ringbuffer_kickoff_initiator_bts. when a thread updates the cp's read pointer, it dumps the backtrace of that thread
Changed the names of the gpu registers CALLBACK_ADDRESS and CALLBACK_CONTEXT to the correct names.
Added a note about CP_PROG_COUNTER
Added CP_RB_WPTR to the gpu register table
Added notes about CP_RB_CNTL and CP_RB_RPTR_ADDR. Both aren't necessary for HLE
Changed name of UNKNOWN_0E00 gpu register to TC_CNTL_STATUS. Games only seem to write 1 to it (L2 invalidate)
* Added controller hotkeys setting
Added option to disable controller hotkeys
Minor Changes
* Fixed locked input system
The input system lock should be released even if a controller is not connected.
Implemented Controller Hotkeys
Added controller hotkeys
Added guide button support for XInput and winkey
The hotkey configurations can be found in HID -> Display controller hotkeys
If the Xbox Gamebar overlay is enabled then use the Back button instead of the Guide button.
- Fixed hotkey thread destruction
- Fixed XINPUT_STATE by padding 4 bytes
- Added hotkey vibration for user feedback
- Replaced MessageBoxA with ImGuiDialog::ShowMessageBox

PM4 buffer handling made a virtual member of commandprocessor, place the implementation/declaration into reusable macro files. this is probably the biggest boost here.
Optimized SET_CONSTANT/ LOAD_CONSTANT pm4 ops based on the register range they start writing at, this was also a nice boost
Expose X64 extension flags to code outside of x64 backend, so we can detect and use things like avx512, xop, avx2, etc in normal code
Add freelists for HIR structures to try to reduce the number of last level cache misses during optimization (currently disabled... fixme later)
Analyzed PGO feedback and reordered branches, uninlined functions, moved code out into different functions based on info from it in the PM4 functions, this gave like a 2% boost at best.
Added support for the db16cyc opcode, which is used often in xb360 spinlocks. before it was just being translated to nop, now on x64 we translate it to _mm_pause but may change that in the future to reduce cpu time wasted
texture util - all our divisors were powers of 2, instead we look up a shift. this made texture scaling slightly faster, more so on intel processors which seem to be worse at int divs. GetGuestTextureLayout is now a little faster, although it is still one of the heaviest functions in the emulator when scaling is on.
xe_unlikely_mutex was not a good choice for the guest clock lock, (running theory) on intel processors another thread may take a significant time to update the clock? maybe because of the uint64 division? really not sure, but switched it to xe_mutex. This fixed audio stutter that i had introduced to 1 or 2 games, fixed performance on that n64 rare game with the monkeys.
Took another crack at DMA implementation, another failure.
Instead of passing as a parameter, keep the ringbuffer reader as the first member of commandprocessor so it can be accessed through this
Added macro for noalias
Applied noalias to Memory::LookupHeap. This reduced the size of the executable by 7 kb.
Reworked kernel shim template, this shaved like 100kb off the exe and eliminated the indirect calls from the shim to the actual implementation. We still unconditionally generate string representations of kernel calls though :(, unless it is kHighFrequency
Add nvapi extensions support, currently unused. Will use CPUVISIBLE memory at some point
Inserted prefetches in a few places based on feedback from vtune.
Add native implementation of SHA int8 if all elements are the same
Vectorized comparisons for SetViewport, SetScissorRect
Vectorized ranged comparisons for WriteRegister
Add XE_MSVC_ASSUME
Move FormatInfo::name out of the structure, instead look up the name in a different table. Debug related data and critical runtime data are best kept apart
Templated UpdateSystemConstantValues based on ROV/RTV and primitive_polygonal
Add ArchFloatMask functions, these are for storing the results of floating point comparisons without doing costly float->int pipeline transfers (vucomiss/setb)
Use floatmasks in UpdateSystemConstantValues for checking if dirty, only transfer to int at end of function.
Instead of dirty |= (x == y) in UpdateSystemConstantValues, now we do dirty_u32 |= (x^y). if any of them are not equal, dirty_u32 will be nz, else if theyre all equal it will be zero. This is more friendly to register renaming and the lack of dependencies on EFLAGS lets the compiler reorder better
Add PrefetchSamplerParameters to D3D12TextureCache
use PrefetchSamplerParameters in UpdateBindings to eliminate cache misses that vtune detected
Add PrefetchTextureBinding to D3D12TextureCache
Prefetch texture bindings to get rid of more misses vtune detected (more accesses out of order with random strides)
Rewrote DMAC, still terrible though and have disabled it for now.
Replace tiny memcmp of 6 U64 in render_target_cache with inline loop, msvc fails to make it a loop and instead does a thunk to their memcmp function, which is optimized for larger sizes
PrefetchTextureBinding in AreActiveTextureSRVKeysUpToDate
Replace memcmp calls for pipelinedescription with handwritten cmp
Directly write some registers that dont have special handling in PM4 functions
Changed EstimateMaxY to try to eliminate mispredictions that vtune was reporting, msvc ended up turning the changed code into a series of blends
in ExecutePacketType3_EVENT_WRITE_EXT, instead of writing extents to an array on the stack and then doing xe_copy_and_swap_16 of the data to its dest, pre-swap each constant and then store those. msvc manages to unroll that into wider stores
stop logging XE_SWAP every time we receive XE_SWAP, stop logging the start and end of each viz query
Prefetch watch nodes in FireWatches based on feedback from vtune
Removed dead code from texture_info.cc
NOINLINE on GpuSwap, PGO builds did it so we should too.
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
