Stub XamVoiceSubmitPacket
Stubs for __CAP_Start_Profiling/End_Profiling/Enter_Function/Exit_Function
add a note about io_status_block in NtDeviceIoControlFile, change the param's type
move the X_IOCTL_ constants from NtDeviceIoControlFile's body into xbox.h
add X_STATUS_INVALID_IMAGE_FORMAT to xbox.h
Implement XexLoadImageHeaders
Much more correct version of IoCreateDevice, properly initializes/allocates device extension data
Stub version of IoDeleteDevice
Open the quickstart guide in the browser the first time a user opens the emulator
Add some persistent flags that are stored in the registry on windows, not in the config. These are just used to indicate whether one-time tasks have run, like showing the quickstart guide. On non-windows platforms a default value is returned that skips any of these tasks so they don't run every single time.
If the user opens a .iso file, show a warning telling them that we do not condone or support piracy. If the user closes the messagebox within two seconds set a sticky flag that will show them the warning every time instead. Otherwise the warning is never shown again. The Beep function is used to spook them a bit, to hopefully make them less likely to skip the message
If a user opens an archive file, which we do not support, explain to them that they're dumb.
Removed messages intended to "catch" pirates. If they're out there, we don't want to know about them. A huge chunk of the discourse on our discord is now about piracy. Hopefully these changes will deter them from coming to us for now, but some of these messages may backfire
properly byteswap r13 for spinlock
Add PPCOpcodeBits
stub out broken fpscr updating in ppc_hir_builder. it's just code that repeatedly does nothing right now.
add note about 0 opcode bytes being executed to ppc_frontend
Add assert to check that function end is greater than function start, can happen with malformed functions
Disable prefetch and cachecontrol by default, automatic hardware prefetchers already do the job for the most part
minor cleanup in simplification_pass, dont loop optimizations, let the pass manager do it for us
Add experimental "delay_via_maybeyield" cvar, which uses MaybeYield to "emulate" the db16cyc instruction
Add much faster/simpler way of directly calling guest functions, no longer have to do a byte by byte search through the generated code
Generate label string ids on the fly
Fix unused function warnings for prefetch on clang, fix many other clang warnings
Eliminated majority of CallNativeSafes by replacing them with naive generic code paths.
^ Vector rotate left, vector shift left, vector shift right, vector shift arithmetic right, and vector average are included
These naive paths are implemented small loops that stash the two inputs to the stack and load them in gprs from there, they are not particularly fast but should be an order of magnitude faster than callnativesafe
to a host function, which would involve a call, stashing all volatile registers, an indirect call, potentially setting up a stack frame for the arrays that the inputs get stashed to, the actual operations, a return, loading all volatile registers, a return, etc
Added the fast SHR_V128 path back in
Implement signed vector average byte, signed vector average word. previously we were emitting no code for them. signed vector average byte appears in many games
Fix bug with signed vector average 32, we were doing unsigned shift, turning negative values into big positive ones potentially
Rather than using `n * 1024 * 1024`, this adds a convenient `_MiB`/`_KiB` user-literal to the new `literals.h` header to concisely describe units of memory in a much more readable way. Any other useful literals can be added to this header. These literals exist in the `xe::literals` namespace so they are opt-in, similar to `std::chrono` literals, and require a `using namespace xe::literals` statement to utilize it within the current scope.
I've done a pass through the codebase to replace trivial instances of `1024 * 1024 * ...` expressions being used but avoided anything that added additional casting complexity from `size_t` to `uint32_t` and such to keep this commit concise.
XMountUtilityDrive code tries reading/writing from \Device\Harddisk0\Cache0 / Cache1 / Partition0, NullDevice handling \Device\Harddisk0 will make that code think that the reads/writes were successful, so the utility-drive mount can proceed without failing.
Changed XEPACKEDSTRUCT to #pragma pack, added setters for some fields that didn't have them, named some anonymous structs which might help with other compilers.
GetBlockHash now visits upper-level hash tables (if needed) to check the active_index flag that decides if secondary hash-block should be used or not.
This should give better support for CON packages, important for X360 profiles/game saves (some well-used profiles can be heavily fragmented)
Previous code would give wrong results for those types of packages as the block_shift would cancel itself out, moving it to happen afterward let it give the right result though, probably a mistake while reversing it.
(eg. block 0 would give 0xB000, but that's wrong for non-read_only packages as 0xA000 and 0xB000 are reserved for the first hash-table there, fixed code returns the correct 0xC000 offset)
Also changed it to a multiply & renamed it to blocks_per_hash_table to make it more obvious what the purpose is.
