* Swap write access mode for read write
Opening with access mode w will erase the opened file. We do not want this.
* Create mode
Opening with write access was previously the only way to create a file through open, so add a separate FileAccessMode that uses the write access mode to create files.
* Update file_system.cpp
Remove a hack added to posix_rename to bypass the file clearing behaviors of FileAccessMode::Write
* Check access mode in read functions
Write-only files cause the EBADF return on the various read functions. Now that we're opening files differently, properly handling this is necessary.
* Separate appends into proper modes
Fixes a potential regression from one of my prior PRs, and ensures the Write | Append flag combo also behaves properly in read-related functions.
* Move IsWriteOnly check after device/socket reads
file->f is only valid for files, so checking this before checking for sockets/devices will cause access violations.
* Fix issues
Now that Write is identical to ReadWrite, internal uses of Write need to be swapped to my new Create mode
* Fix remaining uses of FileAccessMode write to create files
Missed these before.
* Fix rebase
* Add stubbed get_authinfo (#3722)
* mostly stubbed get_authinfo
* Return value observed on console if get_authinfo was called for the current thread, esrch otherwise

These are used by LLE libSceVideodec.
From decompiling the two GnmDriver libraries, it seems like sceGnmDrawInitToDefaultContextStateInternalCommand inlines a call to sceGnmDrawInitToDefaultContextState, so I've replaced that with an actual call to the function for readability.
sceGnmDrawInitToDefaultContextStateInternalSize is one to one with decomp.

Reserved memory counts here, so we need to use !IsFree instead of IsMapped.
I swear this is like the 10th time I've messed this sorta thing up. Seems like it's the last case of this type of mistake in our current code though.
* Some structs and function definitions
* Fill in remaining function definitions and structs
The original variants of GetIdToken and GetAuthorizationCode use an online id instead of user id.
The V3 functions use the same internal function, but with a different flag. Unless games show me something different, they likely use the same structs, and definitely use the same parameters.
* Some errors
* Minor formatting change
* Some more errors
* GetIdToken error cases
* Remaining error cases
Just need to tackle request-related logic now.
* Basic request handling
Seems to internally behave similarly to libSceNpManager, but the actual data stored in libSceNpAuth requests appears to be different, so I've kept everything separated.
* NpAuthRequest usage
Again, behavior mirrors libSceNpManager request behavior, though it appears to be a separate implementation.
The only time libSceNpAuth uses libSceNpManager is to actually send the requests, where the act of sending a request involves creating a completely separate NpManager request, using NpManager functions to retrieve the desired data, then deleting the underlying NpManager request. All of this would happen inside GetAuthorizationCode and GetIdToken.
* Oops
* Missing mutexes
* Default output variables to zero
Not sure what all games might check for here, but setting the outputs to zero is probably safe.
* Implement sceNpCheckPlus
* Rework request storage
We'll need to store more data to "fake" async requests.
* sceNpAbortRequest
Pretty simple to add, so might as well.
* Formatting changes
* Async request logic
There's probably some things I'm getting wrong for cases where PSN is connected, but for reasons that should be pretty obvious, learning how that all works is a little more involved than the PSN disconnected results.
* Add missing error check
* Update np_manager.cpp
* Add a mutex to prevent concurrent reads/writes to g_requests
I imagine multi-threading is a lot more commonly used with the async functions, though I haven't tested enough to know.
* Update np_manager.h
* Move request creation to separate internal function
* Oops
Not sure how that got missed, but good thing I spotted it
* Oops
For now, I've included up to Windows 11 22H2 in the workaround.
I've only personally seen reports of issues on Windows 11 21H2, but better safe than sorry (considering Windows 10 22H2 has issues).
Based on the games I've checked, it seems like the service label parameter of sceNpTrophyCreateContext is what determines the trophy list.
Since we're already storing the service label in our contexts, and we're already extracting all trophy lists, all that needs doing is using the service label to select the right trophy list.
* SearchFree adjustments
* Robust address validation
I've adjusted IsValidAddress to take in a size, and check whether the whole range is contained in vma map.
If no size is provided, the function reverts to the old form of address validation instead.
* Map around gaps
As is, this should work mostly.
Only remaining issue is adding logic to pass the "mapped regions" to the guest vma map (and make such logic cross-platform).
* Initialize vma_map using gaps
This should allow memory code to catch any issues from address space gaps, and prevent non-fixed mappings from jumping to a location that isn't actually available.
* Clang
* Fix compile
* Clang
* Fix compile again
* Set system_managed_base and system_managed_size based on
Many places in our code use system_managed_base as the minimum mappable address, ensure this fact remains the same on Windows to prevent potential bugs.
* Reduce address validation in SearchFree
Allows SearchFree to function when a certain Windows GPU driver goes and reserves the whole system managed area.
Since SearchFree is only called on flexible addresses, allowing this particular case, where addresses are in bounds, but there's not enough space to map, should be safe enough.
* Bump address space size further
To handle Madden NFL 16 (and any games like it)
* More thorough logging of available memory regions
Should help with spotting weirdness.
* Formatting fixes
* Clang
* Slight reduction of user space
Still large enough to handle EA's shenanigans, but small enough that Linux doesn't break.
* Assert on VirtualQuery failure
* Extra debugging information
* Further reduce user space
This will unfix most of EA's titles, but UFC will still work.
Older windows versions support the high addresses, but trying to actually use them causes significant performance issues.
* Extra debugging info
Just in case other testers still run into issues.
* Remove debug logging
* Revert user space increases
Technically this constant is still higher than before, but weird side effects of our old logic resulted in a max address somewhere around this in main.
* address_space: Support expanded virtual memory space on macOS.
Co-Authored-By: squidbus <175574877+squidbus@users.noreply.github.com>
* Move address space constants to address_space.cpp
This ensures that all code must use the calculated address space memory values instead of the constants, since the calculated values can differ based on the platform.
This does require slight modification to thread state and gnmdriver code, since both were already using these constants directly.
* Workaround Windows 10 limitations
If a Windows 10 device is detected, use a lower value for USER_MAX to prevent system-wide hangs in VirtualAlloc2 calls.
* Fix compile for Windows-Qt
* Move tessellation_factors_ring_addr initialization to sceGnmGetTheTessellationFactorRingBufferBaseAddress
* Set image base address on Windows
This seems to work fine on Windows 11, needs testing from Windows 10 due to the previously discussed bugs.
* Set Linux executable base to 0x700000000000
This allows Linux to map the full user space without any workarounds.

* Basic formatting changes
* Reduce USER_MAX on Linux
Seems like finding a reliable way to move shadPS4's position in memory is difficult, for now limit the user size so we aren't trying to overwrite ourselves.
* Move memory and address_space variables.

Module relocation is not thread safe, games calling LoadAndStartModule on multiple threads can invalidate pointers while iterating through m_modules.
This fixes crashes in some apps on Windows.
* Add RNG device
* rng device implementation
Tailored around libSceSsl2's usage, and based on fpPS4's implementation.
* Device file function types and log fixups
* Updated creates
Updates device file create functions to be the same as the directory file create functions.
* Fix compile
* Includes cleanup
Generally preferred to have full paths. Also removed some unused imports too.
* Fix buffer size
* Bring back cstdlib imports
Needed for Mac OS.
* video_core: Refactor render target bind to allow disabling MSAA
* video_core: Implement swapping of backing samples
* clang format
* video_core: Better implementation
Instead of downgrading to 1 sample, always try to match depth samples. This avoids needing to copy depth-stencil attachment and copying multisampled stencil is not possible on some vendors
* video_core: Small bugfixes
* image: Add null check
* vk_rasterizer: Swap backing samples on resolve dst
* vk_presenter: Reset backing samples before present
* video_core: Small refactor to make this implementation better
* reinterpret: Fix channel check for degamma
Seems this was simpler than I thought, hardware doesn't apply degamma on the W channel regardless of swizzle
* image: Add missing end rendering call
* blit_helper: Fix bug in old reinterpret path
* blit_helper: Remove unused layer vertex
Should be used in the future if copying many layers is needed
* vk_rasterizer: Apply suggestion
* vk_rasterizer: More bind refactor
* vk_instance: Re-enable extensions
* Add configurable extra memory
* lowercase getter and setter
* Refactor memory setup to configure maximum memory limits at runtime
* sir clang offnir, the all-formatting
* Correctly update BackingSize on W*ndows too
* small format change
* remove total_memory_to_use from the header
* i have no idea how to name this commit
"addressing review comments" is a good name i guess
* Do not include extraDmem in the general config
* Fix flag handling on Windows
Fixes a weird homebrew kalaposfos made
* Fix backing protects
Windows requires that protections on areas committed through MapViewOfFile functions are less than the original mapping.
The best way to make sure everything works is to VirtualProtect the code area with the requested protection instead of applying prot directly.
* Fix error code for sceKernelMapDirectMemory2
Real hardware returns EINVAL instead of EACCES here
* Fix prot setting in ProtectBytes
* Handle some extra protection-related edge cases.
Real hardware treats read and write as separate perms, but appends read if you call with write-only (this is visible in VirtualQuery calls)
Additionally, execute permissions are ignored when protecting dmem mappings.
* Properly handle exec permission behavior for memory pools
Calling sceKernelMemoryPoolCommit with executable permissions returns EINVAL, mprotect on pooled mappings ignores the exec protection.
* Clang
* Allow execution protection for direct memory
Further hardware tests show that the dmem area is actually executable, this permission is just hidden from the end user.
* Clang
* More descriptive assert message
* Align address and size in mmap
Like most POSIX functions, mmap aligns address down to the nearest page boundary, and aligns address up to the nearest page boundary.
Since mmap is the only memory mapping function that doesn't error early on misaligned length or size, handle the alignment in the libkernel code.
* Clang
* Fix valid flags
After changing the value, games that specify just CpuWrite would hit the error return.
* Fix prot conversion functions
The True(bool) function returns true whenever value is greater than 0. While this rarely manifested before because of our wrongly defined CpuReadWrite prot, it's now causing trouble with the corrected values.
Technically this could've also caused trouble with games mapping GpuRead permissions, but that seems to be a rare enough use case that I guess it never happened?
I've also added a warning for the case where `write & !read`, since we don't properly handle write-only permissions, and I'm not entirely sure what it would take to deal with that.
* Fix some lingering dmem issues
ReleaseDirectMemory was always unmapping with the size parameter, which could cause it to unmap too much. Since multiple mappings can reference the same dmem area, I've calculated how much of each VMA we're supposed to unmap.
Additionally, I've adjusted the logic for carving out the free dmem area to properly work if ReleaseDirectMemory is called over multiple dmem areas.
Finally, I've patched a bug with my code in UnmapMemory.
* Remove mapped dmem type
Since physical addresses can be mapped multiple times, tracking mapped pages is not necessary.
This also allows me to significantly simplify the MapMemory physical address validation logic.
* Proper implementation for sceKernelMtypeprotect
I've rewritten SetDirectMemoryType to use virtual addresses instead of physical addresses, allowing it to be used in sceKernelMtypeprotect.
To accommodate this change, I've also moved address and size alignment out of MemoryManager::Protect
* Apply memory type in sceKernelMemoryPoolCommit
* Organization
Some potentially important missing mutexes, removed some unnecessary mutexes, moved some mutexes after early error returns, and updated copyright dates
* Iterator logic cleanup
Missing end check in ClampRangeSize, and adjusted VirtualQuery and DirectMemoryQuery.
* Clang
* Adjustments
* Properly account for behavior differences in MapDirectMemory2
Undid the changes to direct memory areas, added more robust logic for changing dma types, and fixed DirectMemoryQuery to return hardware-accurate direct memory information in cases where dmas split here, but not on real hardware.
I've also changed MapMemory's is_exec flag to a validate_dmem flag, used to handle alternate behavior in MapDirectMemory2. is_exec is now determined by the use of MemoryProt::CpuExec instead.
* Clang
* Add execute permissions to physical backing
Needed for executable mappings to work properly on Windows, fixes regression in RE2 with prior commit.
* Minor variable cleanup
* Update memory.h
* Prohibit direct memory mappings with exec protections
Did a quick hardware test to confirm, only seems to be prohibited for dmem mappings though.
* Update memory.cpp
* 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
* Implement sceKernelMemoryPoolGetBlockStats
Not entirely sure on the logic behind the cached blocks work, but flushed blocks seems to just be based on committed direct memory.
* Fix comment
* Refactor direct memory areas
At this point, swapping the multiple booleans for an enum is cleaner, and makes it easier to track the state of a direct memory area.
I've also sped up the logic for mapping direct memory by checking for out-of-bounds physical addresses before looping, and made the logic more solid using my dma type logic.
* Fix PoolCommit assert
Windows devices will throw an access violation if we don't check for iterator reaching end.
