ameerj 48b09cc56d kernel: KScopedReservation implementation
This implements KScopedReservation, allowing resource limit reservations to be more HW accurate, and release upon failure without requiring too many conditionals.

Chloe e62886ead0 kernel: Unify result codes (#5890)
* kernel: Unify result codes

Drop the usage of ERR_NAME convention in kernel for ResultName. Removed seperation between svc_results.h & errors.h as we mainly include both most of the time anyways.

* oops

* rename errors to svc_results

Lioncash 6764c7ce52 k_address_arbiter: Unfold R_UNLESS macros
Allows for more descriptive error messages and also doesn't hide
control-path exit returns from the reader.

Lioncash 8884e73c8b k_address_arbiter: Remove unnecessary usages of std::addressof
This is a useful function in a generic context or with types that
overload unary operator&. However, primitives and pointers will never do
this, so we can opt for a more straightforward syntax.

Lioncash c8cc1c301e k_address_arbiter: Remove dead code
This code is never used, so we can remove it. It's in version control,
so it can always be brought back when needed.

Lioncash 8618ac9b8b svc: Provide more detailed error logs for svc functions
Allows SVC calls to have much more informative information during error
cases. This also doesn't hide control flow returns from the reader.

Lioncash 7da83ef6f7 k_affinity_mask: Avoid implicit truncation to bool
This can cause compiler warnings. Instead, we can explicitly add a
boolean expression around it to naturally turn the result into a bool.

Lioncash 9fb1a47658 k_priority_queue: Unfold several declval usages
Given these are only used as function existence checks, we can simplify
some usages of declval, given they aren't particularly useful here.

Reduces a few template instantiations, which at most reduces compile
times a tiny bit.

Lioncash 4431b499d0 k_priority_queue: Resolved reserved identifier
An identifier containing a starting underscore followed by a capital
letter is reserved by the standard. It's trivial to avoid this by moving
the underscore to the end of the identifier.

While the likelihood of clashing here being minimal, we can turn a
"should not break" scenario into a definitive "will not break" one, so
why not?.

ReinUsesLisp 8bfa4d6dbf core/memory: Read and write page table atomically
Squash attributes into the pointer's integer, making them an uintptr_t
pair containing 2 bits at the bottom and then the pointer. These bits
are currently unused thanks to alignment requirements.

Configure Dynarmic to mask out these bits on pointer reads.

While we are at it, remove some unused attributes carried over from
Citra.

Read/Write and other hot functions use a two step unpacking process that
is less readable to stop MSVC from emitting an extra AND instruction in
the hot path:

 mov         rdi,rcx
 shr         rdx,0Ch
 mov         r8,qword ptr [rax+8]
 mov         rax,qword ptr [r8+rdx*8]
 mov         rdx,rax
-and         al,3
 and         rdx,0FFFFFFFFFFFFFFFCh
 je          Core::Memory::Memory::Impl::Read<unsigned char>
 mov         rax,qword ptr [vaddr]

- For `std::same_as`, add missing include of `<concepts>`.

  and use that instead.

  This would also be found in `<concepts>`, but unlike `std::same_as`,
  `std::convertible_to` is not yet implemented in libc++, LLVM's STL
  implementation - not even in master.  (In fact, `std::same_as` is the
  *only* concept currently implemented.  For some reason.)

comex 086238f1ac Fix "explicitly defaulted but implicitly deleted" warning
`PhysicalCore`'s move assignment operator was declared as `= default`,
but was implicitly deleted because `PhysicalCore` has fields
of reference type.  Switch to explicitly deleting it to avoid a Clang
warning.

The move *constructor* is still defaulted, and is required to exist due
to the use of `std::vector<PhysicalCore>`.

ReinUsesLisp a13623c68b kernel: Implement host thread register methods without locking
Locks on GetCurrentHostThreadID were causing performance issues
according to Visual Studio's profiler. It was consuming twice the time
as arm_interface.Run(). The cost was not in the function itself but in
the lockinig it required.

Reimplement these functions using atomics and static storage instead of
an unordered_map. This is a side effect to avoid locking and using linked
lists for reads.

Replace unordered_map with a linear search.

lat9nq 61519c20c3 configuration: implement per-game configurations (#4098)
* Switch game settings to use a pointer

In order to add full per-game settings, we need to be able to tell yuzu to switch
to using either the global or game configuration. Using a pointer makes it easier
to switch.

* configuration: add new UI without changing existing funcitonality

The new UI also adds General, System, Graphics, Advanced Graphics,
and Audio tabs, but as yet they do nothing. This commit keeps yuzu
to the same functionality as originally branched.

* configuration: Rename files

These weren't included in the last commit. Now they are.

* configuration: setup global configuration checkbox

Global config checkbox now enables/disables the appropriate tabs in the game
properties dialog. The use global configuration setting is now saved to the
config, defaulting to true. This also addresses some changes requested in the PR.

* configuration: swap to per-game config memory for properties dialog

Does not set memory going in-game. Swaps to game values when opening the
properties dialog, then swaps back when closing it. Uses a `memcpy` to swap.
Also implements saving config files, limited to certain groups of configurations
so as to not risk setting unsafe configurations.

* configuration: change config interfaces to use config-specific pointers

When a game is booted, we need to be able to open the configuration dialogs
without changing the settings pointer in the game's emualtion. A new pointer
specific to just the configuration dialogs can be used to separate changes
to just those config dialogs without affecting the emulation.

* configuration: boot a game using per-game settings

Swaps values where needed to boot a game.

* configuration: user correct config during emulation

Creates a new pointer specifically for modifying the configuration while
emulation is in progress. Both the regular configuration dialog and the game
properties dialog now use the pointer Settings::config_values to focus edits to
the correct struct.

* settings: split Settings::values into two different structs

By splitting the settings into two mutually exclusive structs, it becomes easier,
as a developer, to determine how to use the Settings structs after per-game
configurations is merged. Other benefits include only duplicating the required
settings in memory.

* settings: move use_docked_mode to Controls group

`use_docked_mode` is set in the input settings and cannot be accessed from the
system settings. Grouping it with system settings causes it to be saved with
per-game settings, which may make transferring configs more difficult later on,
especially since docked mode cannot be set from within the game properties
dialog.

* configuration: Fix the other yuzu executables and a regression

In main.cpp, we have to get the title ID before the ROM is loaded, else the
renderer will reflect only the global settings and now the user's game specific
settings.

* settings: use a template to duplicate memory for each setting

Replaces the type of each variable in the Settings::Values struct with a new
class that allows basic data reading and writing. The new struct
Settings::Setting duplicates the data in memory and can manage global overrides
per each setting.

* configuration: correct add-ons config and swap settings when apropriate

Any add-ons interaction happens directly through the global values struct.
Swapping bewteen structs now also includes copying the necessary global configs
that cannot be changed nor saved in per-game settings. General and System config
menus now update based on whether it is viewing the global or per-game settings.

* settings: restore old values struct

No longer needed with the Settings::Setting class template.

* configuration: implement hierarchical game properties dialog

This sets the apropriate global or local data in each setting.

* clang format

* clang format take 2

can the docker container save this?

* address comments and style issues

* config: read and write settings with global awareness

Adds new functions to read and write settings while keeping the global state in
focus. Files now generated per-game are much smaller since often they only need
address the global state.

* settings: restore global state when necessary

Upon closing a game or the game properties dialog, we need to restore all global
settings to the original global state so that we can properly open the
configuration dialog or boot a different game.

* configuration: guard setting values incorrectly

This disables setting values while a game is running if the setting is
overwritten by a per game setting.

* config: don't write local settings in the global config

Simple guards to prevent writing the wrong settings in the wrong files.

* configuration: add comments, assume less, and clang format

No longer assumes that a disabled UI element means the global state is turned
off, instead opting to directly answer that question. Still however assumes a
game is running if it is in that state.

* configuration: fix a logic error

Should not be negated

* restore settings' global state regardless of accept/cancel

Fixes loading a properties dialog and causing the global config dialog to show
local settings.

* fix more logic errors

Fixed the frame limit would set the global setting from the game properties
dialog. Also strengthened the Settings::Setting member variables and simplified
the logic in config reading (ReadSettingGlobal).

* fix another logic error

In my efforts to guard RestoreGlobalState, I accidentally negated the IsPowered
condition.

* configure_audio: set toggle_stretched_audio to tristate

* fixed custom rtc and rng seed overwriting the global value

* clang format

* rebased

* clang format take 4

* address my own review

Basically revert unintended changes

* settings: literal instead of casting

"No need to cast, use 1U instead"
Thanks, Morph!

Co-authored-by: Morph <39850852+Morph1984@users.noreply.github.com>

* Revert "settings: literal instead of casting
"

This reverts commit 95e992a87c898f3e882ffdb415bb0ef9f80f613f.

* main: fix status buttons reporting wrong settings after stop emulation

* settings: Log UseDockedMode in the Controls group

This should have happened when use_docked_mode was moved over to the controls group
internally. This just reflects this in the log.

* main: load settings if the file has a title id

In other words, don't exit if the loader has trouble getting a title id.

* use a zero

* settings: initalize resolution factor with constructor instead of casting

* Revert "settings: initalize resolution factor with constructor instead of casting"

This reverts commit 54c35ecb46a29953842614620f9b7de1aa9d5dc8.

* configure_graphics: guard device selector when Vulkan is global

Prevents the user from editing the device selector if Vulkan is the global
renderer backend. Also resets the vulkan_device variable when the users
switches back-and-forth between global and Vulkan.

* address reviewer concerns

Changes function variables to const wherever they don't need to be changed. Sets Settings::Setting to final as it should not be inherited from. Sets ConfigurationShared::use_global_text to static.

Co-Authored-By: VolcaEM <volcaem@users.noreply.github.com>

* main: load per-game settings after LoadROM

This prevents `Restart Emulation` from restoring the global settings *after* the per-game settings were applied. Thanks to BSoDGamingYT for finding this bug.

* Revert "main: load per-game settings after LoadROM"

This reverts commit 9d0d48c52d2dcf3bfb1806cc8fa7d5a271a8a804.

* main: only restore global settings when necessary

Loading the per-game settings cannot happen after the ROM is loaded, so we have to specify when to restore the global state. Again thanks to BSoD for finding the bug.

* configuration_shared: address reviewer concerns except operator overrides

Dropping operator override usage in next commit.

Co-Authored-By: LC <lioncash@users.noreply.github.com>

* settings: Drop operator overrides from Setting template

Requires using GetValue and SetValue explicitly. Also reverts a change that broke title ID formatting in the game properties dialog.

* complete rebase

* configuration_shared: translate "Use global configuration"

Uses ConfigurePerGame to do so, since its usage, at least as of now, corresponds with ConfigurationShared.

* configure_per_game: address reviewer concern

As far as I understand, it prevents the program from unnecessarily copying strings.
