- Display xex filenames in title selection.
- Fixed fullscreen controller hotkeys executing from a non-UI thread.
- Fixed recent_titles_entry_amount not disabling if set to <= 0.
- Use RunTitle instead of LaunchPath which does more error checking.
AVX512 has native unsigned integer comparisons instructions, removing
the need to XOR the most-significant-bit with a constant in memory to
use the signed comparison instructions. These instructions only write to
a k-mask register though and need an additional call to `vpmovm2*` to
turn the mask-register into a vector-mask register.
As of Icelake:
`vpcmpu*` is all L3/T1
`vpmovm2d` is L1/T0.33
`vpmovm2{b,w}` is L3/T0.33
As of Zen4:
`vpcmpu*` is all L3/T0.50
`vpmovm2*` is all L1/T0.25
Other half of #2125. I don't know of any title that utilizes this instruction, but I went ahead and implemented it for completeness.
Verified the implementation with `instr__gen_vsubcuw` from #1348. Can be grabbed with:
```
git checkout origin/gen_tests -- src\xenia\cpu\ppc\testing\*vsubcuw.s
```

There's no limit on the number of memory exports in a shader on the real
Xenos, and exports can be done anywhere, including in loops. Now, instead
of deferring the exports to the end of the shader, and assuming that export
allocs are executed only once, Xenia flushes exports when it reaches an
alloc (allocs terminate memory exports on Xenos, as well as individual ALU
instructions with `serialize`, but not handling this case for simplicity,
it's only truly mandatory to flush memory exports before starting a new
one), the end of the shader, or a pixel with outstanding exports is killed.
To know which eM# registers need to be flushed to the memory, traversing
the successors of each exec potentially writing any eM#, and specifying
that certain eM# registers might have potentially been written before each
reached control flow instruction, until a flush point or the end of the
shader is reached.
Also, some games export to sub-32bpp formats. These are now supported via
atomic AND clearing the bits of the dword to replace followed by an atomic
OR inserting the new byte/short.
Move impl of XamAlloc into XamAllocImpl
Implement XamAllocEx
Implement XamIsCurrentTitleDash
Implement XamGetLocaleDateFormat
Implement "stub" of XFileFsDeviceInformation, XFileSectorInformation (log warnings when they're executed so this doesnt get mistaken for an actual implementation)
Added xboxkrnl_memory file
Moved meat of MmAllocatePhysicalMemoryEx into xeMmAllocatePhysicalMemoryEx, exposed its definition via xboxkrnl_memory.
Moved impl of RtlImageHeaderNt into a helper function
Implement RtlImageDirectoryEntryToData
Implement KeSuspendThread
Check for bad handles passed in XOVERLAPPED, fixes crash in 415608D8
… over to referencing state through ppc_context as much as possible, it'll make implementing things like kernel processes much easier in the future
Move forward definitions of kernel types into kernel_fwd.h
Stub implementation of XamLoaderGetMediaInfoEx
Partially implement XamSetDashContext
implement XamGetDashContext
Stub implementation of XamUserIsUnsafeProgrammingAllowed
Stub implementation of XamUserGetSubscriptionType
Expanded the supported object types for ObReferenceObjectByHandle and wrapped the logic for encoding the type in a constexpr function
ObReferenceObjectByName was taking lpstring_t for first param, but the function actually takes X_ANSI_STRING ptr
NtReleaseMutant actually does not return anything from KeReleaseMutant, it just checks the handle and returns whether it was invalid.
Changed the raise/lower irql functions to just set the irql on the pcr instead of setting it on field of Processor, processor is a shared object and irql is per-thread
Semi-stub implementation of KeGetImagePageTableEntry. I locked at it in the HV and got it so the values are in the same range the HV returns + actually reflect the page & memory range, but i doubt its equal to the values the hv returns on real hw. Used by modern dashboards, don't know for what.
Log error message for ObDereferenceObject w/ null ptr.
Allocate a special fixed page that dashboards reference, currently don't know what the data on that page is supposed to be.
Add current_irql field to X_KPCR
Added Device object member of XObject::Type enum
Added some notes about other gpu registers, found a table of register names and indices in xam
stub XeKeysGetConsoleType
Removed the breakpoints in HandleCppException and RtlRaiseException until we have a real implementation of them. Some apps can continue fine afterwards.
Stub version of HalGetCurrentAVPack
Implement MmIsAddressValid
Implement RtlGetStackLimits
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)
Fully defined the structure.
Single copy of it + single timer across all modules, managing it is now the responsibility of KernelState.
add global_critical_region::PrepareToAcquire, which uses Prefetchw on the global crit. We now know we can use Prefetchw on all cpus that have AVX.
add KeQueryInterruptTime, which is used by some dashboards.
add threading::NanoSleep
uses a bitmap that splits up the memory space into 65k blocks per bit. Currently is using the guest virtual address but should be using physical addresses instead.
Currently if a guest does a reserve on a location and then a reserved store to a totally different location we trigger a breakpoint. This should never happen
Also removed the NEGATED_MUL_blah operations. They weren't necessary, nothing special is needed for the negated result variants.
Added a log message for when watched physical memory has a race, it just would be nice to know when it happens and in what games.
