Keeping my heap API definition fixes though, since that's a valid change.
Also adding back libScePadTracker LLE, shadow removed it during rebase, but it should still "work" with these changes.
* improve signal emulation
* make the sce function use the new posix ones
* ifdefing away the issues
* fix me being very tired yesterday night
* let macOS handle SIGRT signals with the native sigaction call instead of an early error return
* windows still has no clue what the fuck is going on
* the loathsome clang-formatter
* fix oact
* return the guest handler, not the host one
* Clear any existing signal mask for game threads.
* don't rely on implementation specific things
* Fix Windows support and sceKernelRaiseException bug
* Review suggestions
@kalaposfos13 suggested I push these.

* Replace sysmodule enums with table
Dumped this from the 12.52 module, using a script I created.
* Better documentation
* Separate from system libraries
That system folder is going to be getting quite large if I left all the sysmodule stuff in there.
* More arrays from library
* Found another preload list
Ghidra really hates decompiling libSceSysmodule, so I didn't notice this one at first.
Also documented specific versions tied to each preload list.
* Start work on implementation
* Some basic implementations
* Initial stub for module loading
Just enough to see if the logic functions appropriately.
* Clang
* sceSysmoduleLoadModule
Now I need to get sceSysmodulePreloadModuleForLibkernel done so that we don't have bugs from not loading internal LLEs.
* sceSysmoduleLoadModuleInternal
* sceSysmodulePreloadModuleForLibkernel
I have successfully broken quite literally everything.
I shall debug this tomorrow.
* Slight fix
* Maybe fix?
* Change log
Enjoy the log spam 😄
* Increased defined stub count
Now that libc and libSceLibcInternal loads later, all the auto stubs are getting consumed by it.
* sceSysmoduleUnloadModule stub
Also a couple fixes. Sysmodule does pass argc and argv to game modules, but only after loading them once to check binaries.
Shouldn't matter for the most part.
* Clang
* Less stubs
2 thousand is seemingly enough.
* sceSysmoduleLoadModuleInternalWithArg
Doesn't hurt to have, since Apex Legends calls it.
* Oops
* Oops 2
* Rename isModuleLoaded to getModuleHandle
Review comment
* Remove debug game module loads
These cases only trigger when specific sceRegMgr key values are set, and for our purposes, we can treat that case as false.
* Allow preloading to fail
For kalaposfos
* Clang
* Remove SceKernelInternalMemory mapping
Contrary to my initial beliefs, this is very much a hack.
* Unreachable for unpatched code
This will always infinitely loop, making logs extremely large.
* Update linker.cpp
* Avoid storing the Tcb pointer on the stack
* Just return the already stored pointer in GetTcbBase
* Replace uses of GetTcbBase with g_curthread->tcb
* copyright 2025
* sir clang offnir, the all-formatting
* Add support for restarting the emulator with new configurations
- Implement `Restart` function in `Emulator` to enable process relaunch with updated parameters.
- Modify `sceSystemServiceLoadExec` to use the restart functionality.
* Add logging for emulator restart and system service load execution
* Add IPC emulator PID output command
Impl `PID` output command to return the emulator process ID
- required for launches supporting emulator restart
* Add log file append mode support (used after restarting to keep the same log file)
* Keep game root between restarts
* add --wait-for-debugger option flag
* add --wait-for-pid flag
used for sync between parent & child process during restart
* impl restart via ipc
* fix override game root
* add qt flags to allow restart
* Fix isDevKit
Previously, isDevKit could increase the physical memory used above the length we reserve in the backing file.
* Physical backing for flexible allocations
I took the simple approach here, creating a separate map for flexible allocations and pretty much just copying over the logic used in the direct memory map.
* Various fixups
* Fix mistake #1
* Assert + clang
* Fix 2
* Clang
* Fix CanMergeWith
Validate physical base for flexible mappings
* Clang
* Physical backing for pooled memory
* Allow VMA splitting in NameVirtualRange
This should be safe, since with the changes in this PR, the only issues that come from discrepancies between address space and vma_map are issues related to vmas being larger than address space mappings. NameVirtualRange will only ever shrink VMAs by naming part of one.
* Fix
* Fix NameVirtualRange
* Revert NameVirtualRange changes
Seems like it doesn't play nice for Windows
* Clean up isDevKit logic
We already log both isNeo and isDevKit in Emulator::Run, so the additional logging in MemoryManager::SetupMemoryRegions isn't really necessary.
I've also added a separate constant for non-pro devkit memory, as suggested.
Finally I've changed a couple constants to use the ORBIS prefix we generally follow here, instead of the SCE prefix.
* Erase flexible memory contents from physical memory on unmap
Flexible memory should not be preserved on unmap, so erase flexible contents from the physical backing when unmapping.
* Expand flexible memory map
Some games will end up fragmenting the physical backing space used for flexible memory. To reduce the frequency of this happening under normal circumstances, allocate the entirety of the remaining physical backing to the flexible memory map.
This is effectively a workaround to the problem, but at the moment I think this should suffice.
* Clang
* Remove checks for module version_major and version_minor
Following this rule broke linking for some libraries, and introduced extra effort needed to get some homebrew running.
* Clang
* Fix rebase
* Disable libSceSsl HLE
Real hardware uses a title workaround to determine if base libSceSsl is needed. Currently, this title workaround applies to absolutely nothing.
Under normal circumstances, this mapping should only occur when libSceGnmDriver initializes. From what I can tell, this can be after game code starts running. Until there's a better way to accurately handle this, allocating this memory breaks some games.
This revert fixes the regression in games using the GFD engine.
* Emulate memory behavior of libSceGnmDriver _DT_INIT
Due to the unique way some games check for sceKernelAllocateDirectMemory failures, emulating this properly is necessary.
* Clang
* Fix address input for direct memory call
* Fix bug with DirectQueryAvailable
Missed this in my prior PR.
* DirectQueryAvailable fix
Fixes error cases to be more hardware accurate.
