Aimed to fix Ender Magnolia missing shader textures. Main example is Yolvan character bullets.
By using windows version of the game, dxvk lib to make it vulkan, and renderdoc, it was possible to capture bullets, and by tracking backward composition and comparing with a similar scene from eden with missing bullets, it was possible to unveil the missing functionality: conditional Phi inputs resolve for bindless handles.
By ignoring the boolean predicate register in the shader, handles for these shaders were resolving to some old value instead of proper live conditional ones.
TESTS:
-Compare Yolvan bullets
-Usual roam on main titles for regression check.

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.

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

There were two settings related to Controller applet:
-"disable controller applet", which is a boolean toggle;
-"controller configuration" applet mode, which is a "Real"/"Custom" picker;
All i did was to nuke the toggle and add a third option "Disabled" to the picker.
Users which used the disable toggle will have to pick Disabled;
Real/Custom settings wont be affected since their indexes remains.

A new NSO compression method was introduced in Switch 22.0.0. This is a
customized variant of zstd and is used when NSO flags have bit 7 set.
Key characteristics:
- ZSTD_MAGICNUMBER is set to 0x4349425A (b'ZBIC') instead of 0xFD2FB528
- ZSTD_LEGACY_SUPPORT is set to 0
- ZSTD_TRACE is set to 1, zstd version used is 1.5.7 (10507)
- FSE_readNCount is replaced with a BIC (Binary Interpolative Coding)
version which improves compression of entropy tables significantly
Source: https://switchbrew.org/wiki/22.0.0
Implementation:
- Detect ZBIC segments via NSO flag bit 7 (NsoFlags_UseZbicCompression)
and/or ZBIC magic scan in nso.cpp
- Fall back to LZ4 when ZBIC is not detected or returns unexpected size
- Handle segment 0 alternate offset (0x100 vs 0x108) for both ZBIC and LZ4

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`

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

So, about Absolum's no overlay applet P2 issue:
The fallback controller applet ignored keep_controllers_connected, according comment: "This makes it easy to connect the desired controllers". Unfortunately it was not good enough. It disconnected every controller, then reconnected only the minimum player count. That disconnect interacts with some guests (absolum in this case) causing undesired behaviors.
The fix is entwined to original routine but it is a lot simple tho: preserves compatible connected controllers within the requested player range, while the existing routine configures only the remaining slots.
This may fix some games, and should not harm others. Let us give it a go.

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.

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.

Replaces all instances of ankerl's unordered map/set with boost's
`unordered_flat_*` classes. This uses std::hash since boost::hash is
actually a lot slower.
Also adds an abstraction layer in `Common` so future changes are quicker
and easier.
Other implementation details:
- ankerl provided hash specializations for tuple and pair, so those were
ported here
- std::erase_if doesn't work on boost, so just used the ADL'd erase_if
This should be about equal or superior performance as unordered_dense for everything except iteration.

this PR reworks IPS parser to be less stupid
what do i mean by this? well generally give it a bit of
love so it doesn't do a lot of unsound allocations
also simplify the logic greatly (and use memcmp() string idiom
instead of trusting the compiler so blindly...)
no this doesn't mean to uber optimize IPS to handle 999 gb/s
it's more so it doesn't outright crash with edge cases
as the previous codebase was quite spaghetty
also the major overhead is obviously the vector shenanigans
and the I/O -- but thats out of scope
Test that IPSwitch mods still properly work WITH ANY GAME

This one deserves a long story, but imma try to resume:
During investigating Absolum 1.2 black screen of death upon loading intro video, i've discovered guest was aborting for failing to allocate room for the video.
By logging everything prior to crash and decoding guest side instructions managed to confirm its media allocator was reading data faster than it was updating free available bucket list.
Since the IStorage::Read was happening 247 times before the crash, i've decided to add a very small sleep there, and boom, not only Absolum but some other titles got the same issue fixed.
But i was unsatisfied with the sleep and kept tracking guest instructions upstream in order to find a sync point for the read worker and the memory allocation update. But unfortunately the media allocator helpers live in guest, accessing memory directly via MMU, so any sync signaling would need to come from some dynarmic hack.
It's been 6 days now, so i've decided to polish the sleep: Moved it upstream to where i could have access for proper predicate, and added machinery to service and nvhost to support that. Now the sleep is restricted only for nvdec istorage reads. Any other reads will flow normally.
TL;DR: currently our code is so blazing async that guest is capable to request reads before its very self refresh it have freed room to do so. The sleep accepted as broadly stable was 600 us (MICROseconds), and it affects ONLY nvdec chunk reading.
Reports confirm that now videos are smoother now.
Code was polished at my knowledge limits.
Mostly machinery to track when a request comes from a process with nvdec active, and is istorage read.
I can provide more details if it comes to be needed.

An experimental approach to introduce an smarter way to use and access QUAD's capabilities on shaders, suggested by @gidoly some months ago, finally came into something usable; current implementation checks GLASM, GLSL and Vulkan on their own way, stablishes proper emitters and receivers for Quads inside our recompiler, which are the introductions for future changes; checks for support and actual feature bit, OpCodes and mask were added within this PR. Meanwhile the expected behavior was to reduce graphical issues (on games with Quad shaders reliant), we encountered a very slight performance increase depending on what game and shader are actually compiled.

the idea is simple, `std::string{}` adds pressure to the memory allocator
so whats the best next thing we can do? well of course use our stack
its plenty, but we shouldn't be greedy either, BUFSIZ should be a fair amount of
space for any would-be messages anyways
the main idea behind this PR is to remove std::string{} allocations
done with libfmt, that way we have 0-allocs per logging entry
this should 100% remove pressure uneeded from the memory allocator
we should only allocate things that are important, we can use our
trusty fast stack for any string manip we need to do
not await/global lock or do evil things with the memory allocator
obviously stack is thread local already sooo... this is even better
than having to deal with malloc()/free() in any capacity whatsoever
and no clang can't heap ellide this (how would you even?)

This removes the ugly wash from focused game cards, without removing the interaction's cool ripple effects.
I've stumbled upon a reddit complaining about it, and in fact i always hated it but hadn't realized yet.
It happens to any layout.
Joypad users notice more since navigation consists on focusing cards.
Carousel users notice even more coz cards are bigger and always focused.
Border is more than enough to highlight a card, and we want to cherish colors just like creator artists wanted it to be, right?
No chance of bugs. No chance of disagreement (¬¬).
Approve it already so Youtube videos with carousel thumbs get prettier earlier ^^.

This small impl aims to fix an android old visual bug where it could cache/read a base game icon before its update was mounted, so games with update-specific icons kept showing the base icon like almost always (in a way that some players may never have seen the updated icons).
Fix: when scan detects an update matching an already found base game, reload that game’s metadata and refresh only its visible icon if the icon actually changed.
I believe it's polished to the max. No find/scans. When base is found it is tracked via hashmap, and when update is found and conditions met the refresh is triggered.
