thanks to @chrelliott978 for the initial impl, basically clang will yell at you if you dare use wstring_codecvt<> and some other shit, and to be fair one day it will be removed because it's deprecated (but it's c++, we know it will NEVER be deprecated)
either way this makes clang shut up

main idea is basically to manually manage the file backed storage ourselves
basically the libc will use pooled workes who will read off sync data and may or may not use mmap, this detail can vary between libcs, so id rather have one unified concept of "paged file" as opposed to relying on the libc doing what it should
the main benefit is that one doesnt need to call fwrite/fread or whatever, they can just do normal paged file ops and such
this pr has seen changes from mapped flags as well, as some OSes; particularly android, do not enjoy being told to make hugepages that are 1GB in size, especially for lower end devices.

This works provides better emulation on certain GS missing for shader invocation data + geometry pass fallback in qcom/turnip drivers, some of those were provided as community patch by @a.kamaltdinov; which was refined to address the requirements on forced gpu reads; which used to kill some performance on low end devices; now, the stability with some of the graphical problems have been addressed and balanced. Shuffle shaders (SHFFL) are not actually provided on QCOM and turnip drivers, so any game that previously required this stage draw, will now avoid being ignored and tax some performance based on the complexity of the stage draw from now on. This will also address partially some tessellation problems as well.

This PR primarily focuses on upbringing constexpr maps for handlers.
Each time an HLE object of a service is construed, it registers it's own handlers, over and over.
Regardless of whetever it needs them at the moment or not.
Additionally we don't require to keep track of different function pointers amongst each object.
This can be done by overriding the given function instead, as opposed to having a separate
hash map for every given object.
In other words: Remove handlers (and handlers_tipc) map for every instance
then read from a static defined per-class.
- [x] Migrate all HLE functions to new `frozen::map` constexpr time finder
- [ ] Measure if this approach actually makes better codegen
Optional:
- [x] Properly gate all functions (that have versions commented next to them)
- [x] Maybe store `HandlerFnP<>` and `const char*` separately, version gating can go in a different map as well
Information such as name can be used on debug builds, but doesn't particularly help on release as one can consult an external reference (or have an annotated IPC map)

the general idea is to have a common procedure form whom to call
this way theres less "jumping around" for values of different sizes
additionally this **should** allow for better codegen since
most of the u8,u16,u32,u64 can be held within a u64
theoretically this means that you could deifne callbacks in suck
a way that it's essentially as costly as a `mov r64, m64`
but that's not doable due to the fact we have to do translations...
Is this a good change?
Primarily aimed for x86 and ARM to benefit, but I suppose LooooooongArch64 can benefit too.

This was intended to fix Dave the Diver issue, but we found a real silly hid bug, then a maybe broader applet issue:
By testing with John it was found out only the last controller connected worked, the others caused the game to freeze peacefully, no crashes, suggesting some loop or deadlock.
After seeking that lead, it was found that the freeze was caused by a malformed HID history entry when the controller applet removed P2.
Pressing P1 opens the controller applet, then Qt applet disconnects P2, which is expected.
Upon seeking callstack and hid sync path, it was found out that NPad::WriteEmptyEntry:
was using: ReadCurrentEntry().sampling_number + 1
instead of: ReadCurrentEntry().state.sampling_number + 1 (checked AtomicStorage in src\hid_core\resources\ring_lifo.h)
Fixing that fixed the freeze, but killed the sound!
Later handheld/docked was accidentally clicked and sound returned. Good lead.
Then i just had to corner which part of the toggle was causing the refresh and do something similar at the controller applet return routine (PopOutData in library_applet_accessor.cpp). This part seems harmless, but i'm not clearly sure about how proper it is, since it was like a transplant and test operation.
UPDATE:
To try Diablo 3 on my machine it was needed to stub HID function 551.
And to fix all abnormalies like multiple applet requests and crash the function PopOutData was reworked to ensurey idempotency among different applet focus conditions:
focus state changed: updates state and signals if needed
no state change, HLE application frontend: requests focus state changed notification
already pending change message: flag remains true and no duplicate pushed to queue entry

FFmpeg offers two opus decoders:
- libopus, this one is fed the same data (that affects output) as the previous libopus decoder had as well
- native opus decoder: this only takes Float32 samples, we then need to invoke swrescale to translate between s16 (what switch sends) and float32 (what FFmpeg expects), the process is computationally more expensive, but trades off neatly as the native opus decoder is very optimised
It also relegates the handling to FFmpeg, which simplifies existing code (more concretely, by using the "fill/drain" scheme for packets/frames)

This issue was observed in MGS Master Collection Volume II, MGS4: Guns of the Patriots, Chapter 4: Shadow Moses
That title is a bundle, and that specific chapter is a program (MGS 1st stage), launched by a program (MGS4), launched by an application (main title bundle).
Upon decoding guest panic message, it was exposed that an abort was triggered after trying to create a save in nand/temp/gclvar.bak file.
Further instrumentation exposed the error on that file's path, caused from a previous deletion of that folder.
In the same session that folder had been already cleaned and created successfully, which evidences an undesired re-cleaning of the temp structure.
The issue was the fact that the MGS4 to MGS transition also calls EnsureSaveData>...>SaveDataFactory creator, and that was destroying the previous created temp structure. After that stage, the return from MSG to MSG4 was causing the same issue again.
By moving the deletion to the guest application level, the factory creation was called only once, as it should be, and the issue is gone.

This is intended to fix Hades II save loading issue.
By analyzing panic dump it was found out that the error code was 0x160A. By decoding firmware it was found that error comes from 'nn::codec::InitializeHardwareOpusDecoder'.
Further decoding revealed that SDK tries to allocate multiple opus instances, up to the fw limit of 24 instances, and when it receives return error ResultOutOfOpusDecoders (385), a software fallback is gracefully used.
Implementing the limitation and the limit reached error code return makes saves load properly, multiple times in a row in both windows and android.
I still wonder why the game allocates too many parallel instances, but the current implementation is a real fw compliant solution, and whether the 24+ is real or some leak may be investigated later, or not.

Very self-explanatory; implementation of the feature for post-processing shaders for Android (at least for now); will allow users to enhance the graphic quality of video games based on the use of multiple shaders adjustable, presets and more, inspired on the PPSSPP implementation, this feature adds 22 customizable shaders (1 pass) that lives on the overlay of the screen, which means that aside of the capability to chain multiple shaders on the screen, this doesn't have depths (pixel/ depth z-buffer) so it ensures the performance with it's use. Few shaders were a faithful port from PPSSPP with their respective attribution on the shader headers for their respective owners; and there are adaptations from public references/ cinematographic (Anime4K) and the rest are my own addition.

Reduces the page entries from 32 bytes to 8 and rewrites `VirtualBuffer` to be more efficient in memory usage and specifically for large zero regions.
The page table will now only reserve 1GiB instead of 4GiB and of this memory it should only use at most ~8MiB.
This PR has the side effect of using Eden on Windows on low memory systems much more plausible since it would previously require ~10GiB of committable memory at front (despite using ~5-6 at most, inadvertently stalling other processes) where as now it should only require around the amount that it'll actually use.

Storage buffers can span GPU pages that aren't contiguous in host memory, but the buffer cache assumed one contiguous buffer per binding, so anything crossing a mapping boundary read the wrong bytes. Multi-range binding resolves the real segments and presents them to the shader as one buffer, aliasing their memory into a sparse VkBuffer or gathering them into a copy, all of this was mostly fixed by making a path to use sparse on buffers (the same way as texture cache has it) and retrieve properly the mapping ranges to the virtual pages, including the actual structure on the use of binding sparse.
Meanwhile this fixes Monster Hunter Sunbreak z-fighting, bad performance and mostly vertex explosions (coming from the contiguous buffer read from the shader's game) it's only the basis for a further investigation towards how are we gonna treat phi calculations, optimized them and mostly eradicate the currently excess of exposure on the textures where the lightning trace should not being reflected.

Problem: In cyrilic idioms, Absolum won't past beyond 1st area (intro miniboss).
From the user panic i`ve extracted these strings:
> GlobalState.request_next()
> save_state_to_saveGame(...)
> platform.ProcessSave()
> bin_serialize_to_file(...)
> StandaloneTypeModel.Write(SaveGame, ...)
> Write(SaveGame.AdventureSaveSlot, ...)
> Write(PlayerState, ...)
> ProtoBuf.ProtoWriter.WriteString(...) + 0xcc
> ProtoBuf.Helpers.DebugAssert(...)
> Debug.Fail(...)
By debugging ProtoBuf.ProtoWriter.WriteString(...) argument it was found that the string Отлично! (Great! expression for combos between 6 and 30 iirc) was reaching a size comparison of different values and causing an assert in guest side..
It seems the game tries to save highest combo level. I've managed to skip this bug by doing a perfect combo for entire level, so that the problematic word never was generated or attempted to be saved.
After further research, the issue chain was identified: Game maths literal string size via two ways and compare, and one of them was getting replaced by a wrong value due to Eden letting the literal string be interpreted as a real instruction.
Logic added:
const bool pair = decltype(l)::ExtractValue(raw) & 1;
const bool fixed_rt2 = decltype(rt2)::ExtractValue(raw) == 0b11111;
return pair || fixed_rt2;
- pair checks bit 21 (L & 1): register-pair instructions actually use Rt2, so they remain accepted.
- For single-register forms, require Rt2 == 31. The table word fails this check, so NCE leaves it intact.

Altough the solution is a case specific guard, it is data agnostic: This is a true fix to avoid a specific case in which a literal may be interpreted as a valid instruction, without interfering with other true instruction cases.

## Pull Requests
Pull requests are only to be merged by core developers when properly tested and discussions conclude on Discord or other communication channels. Labels are recommended but not required. However, all PRs MUST be namespaced and optionally typed:
```txt
[cmake] refactor: CPM over submodules
[desktop] feat: implement firmware install from ZIP
[hle] stub fw20 functions
[core] test: raise maximum CPU cores to 6
[cmake, core] Unbreak FreeBSD Building Process
```
- The level of namespacing is generally left to the committer's choice.
- However, we never recommend going more than two levels *except* in `hle`, in which case you may go as many as four levels depending on the specificity of your changes.
- Ocassionally, up to two additional namespaces may be provided for more clarity.
- Changes that affect the entire project (sans CMake changes) should be namespaced as `meta`.
- Maintainers are permitted to change namespaces at will.
- Commits within PRs are not required to be namespaced, but it is highly recommended.

## Adding new settings
When adding new settings, use `tr("Setting:")` if the setting is meant to be a field, otherwise use `tr("Setting")` if the setting is meant to be a Yes/No or checkmark type of setting, see [this short style guide](https://learn.microsoft.com/en-us/style-guide/punctuation/colons#in-ui).

AI and LLM use is *strictly* prohibited within our codebase and surrounding community, including issues and comments. This includes using AI or LLMs to write docs/commit messages, debug issues, brainstorm ideas, research concepts, or search the codebase.
AI is notorious for producing low-quality code; be it:
- nonfunctional,
- verbose/inefficient,
- breaking other parts of the codebase,
- or writing/architecting in a completely different style
All code, AI or not, is held under a **strict standard of excellence**. AI/LLM-generated code will fail this test 10 times out of 10.
## Licensing concerns
This is an area of ongoing litigation, and as such, is still very iffy. For the time being, know that allowing AI to ingest the codebase may end up with its copyleft code regurgitated into incompatibly-licensed proprietary or permissive software. For you, this means to **not** feed code into LLMs.
AI models may have also ingested AGPLv3 code, which is license-incompatible with our codebase.
## Vibe-coding
Just don't. If you're not going to put the effort in to understand every line of code you wrote, neither will we, and your patch or pull request will be ignored.
## Commit messages
AI-generated commit messages are absolutely terrible, and your pull request or patch will immediately be rejected if you choose to do this. They are, quite simply, actively detrimental to our understanding of your changes, and if you're not willing to summarize the intent behind your changes, then we're not going to bother reading the code you wrote.
Write concise, simple, and descriptive commit messages that actually convey the proper intent behind what your change is trying to do.
See the [Addendum](#addendum-commit-messages) for an instance of how bad AI models are at commit messages.
## Miscellaneous concerns
- While many environmental concerns about AI are typically blown out of proportion, it *is* a legitimate issue, and should be taken into account.
- Many people have significant concerns over the ethics of AI usage due to inhumane and predatory behavior by large AI companies, particularly Anthropic and OpenAI. This can technically be avoided through the usage of local LLMs.
- LLMs have a tendency to add unicode characters (such as the arrow → and the em-dash — symbols) to their output, which can make viewing code or documents harder on command-line editors and viewers.
- Dedicated coding models--namely Claude--also like to add a lot of comments to overexplain every individual line of code it produces. This actually makes it *harder* to understand the code!
## Unacceptable Use Examples
Here are a few examples of unacceptable use:
- Solving problems
- Slapping a few files and a "please fix bug XYZ" into an LLM is a recipe for disaster that will pretty much never work.
- Fully AI-generated code, aka "vibecoding"
- Writing code based on pseudo-instructions
- If you don't know how to write code, don't. If you've figured out the root cause (preferably without feeding random files into an LLM) and actively know what's going on, provide information to other developers or friends of yours who have knowledge of the language and/or the codebase.
## Addendum: Commit Messages
The patchset for pull request [#3422](https://git.eden-emu.dev/eden-emu/eden/pulls/3422) was fed into several LLMs to generate a commit message. One LLM produced the following:
```txt
profile_manager: Refactor user deletion to use index instead of UUID
This commit improves the user profile deletion flow in the following ways:
1. **UI layer (ConfigureProfileManager)**:
- Replaces UUID-based deletion with index-based deletion
- Passes the selected row index from the tree view to the confirmation dialog
- Emits deleteUser(int index) signal from ConfigureProfileManagerDeleteDialog
- Removes lambda capture and std::function callback in favor of direct signal/slot connection
2. **Delete dialog**:
- Changes SetInfo() signature to accept index instead of accept callback
- Stores index internally and emits it via deleteUser signal on acceptance
- Removes duplicated stable_partition + save logic from RemoveUser()
- Centralizes profile removal and save-file writing in RemoveProfileAtIndex()
4. **Minor follow-up**:
- Adds profile_manager.ResetUserSaveFile() call in PopulateUserList() to ensure consistent state when refreshing the user list
These changes eliminate redundant code, reduce the risk of UUID → index mismatch bugs, and make the deletion path more straightforward and maintainable.
Fixes: potential inconsistency when user order changes between UI and backend
```
This is:
- Needlessly verbose (nobody cares about most of these details)
- Doesn't address the actual purpose of the PR (fixing a double-deletion bug in the profile manager)
- Has unicode arrows (this is bad for command-line editors)
- Uses corporate and word-salad language
Another (code-oriented) LLM output the following:
```txt
profile(manager/ui): switch to index-based deletion and unify removal logic
- Make ConfigureProfileManagerDeleteDialog emit a deleteUser(int) signal instead of taking a callback. Store the target index in the dialog (m_index) and emit it on acceptance.
- Change ConfigureProfileManager to pass an index to SetInfo and to accept an index in DeleteUser. Wire the dialog signal to the new DeleteUser slot.
- Update headers: add the signal and m_index, add TODO to move dialog to a .ui file, and update slot/signature declarations.
- Add ProfileManager::RemoveProfileAtIndex(std::size_t) and refactor RemoveUser(UUID) to call RemoveProfileAtIndex to avoid duplicated removal logic. Ensure the removal path marks saves as needed and writes the user save file.
- Ensure the profile list updates immediately after deletes by calling profile_manager.ResetUserSaveFile() when populating the user list (qlaunch fix).
- Misc: update SPDX copyright year and fix build breakages caused by the API changes.
This consolidates profile removal behavior, fixes potential race conditions in the profile dialog, and removes duplicated removal code.
```
This has all of the same problems as the other one. Needlessly verbose, doesn't address *what* it actually fixes ("consolidates profile removal behavior"... okay, why? What does it fix?), etc. It even has the bonus of totally hallucinating the addition of a method!
On a more "philosophical" note, LLMs tend to be geared towards *corporate language*, as that's what they're trained on. This is why AI-generated commit messages feel like "word salad", and typically pad out the commit message to make it *look* like a lot of things were changed (trust me, it's like that in the corporate world). They typically also drift towards unneeded buzzwords and useless implementation details.
