Makes the interface future-proofed for supporting other platforms in the event we ever support platforms with differing pointer sizes. This way, we have a type in place that is always guaranteed to be able to represent a pointer exactly.
These aren't directly important or commonly used within the process, so
we can move these to the bottom to allow everything else to be more
likely to be within a cache line.
Profiling shows that this is a highly contested mutex, causing dimishing
results compared to a OS lock. std::mutex implementations can spin for a
while before falling back to an OS lock.
This avoids wasting precious CPU cycles in a no-op.
* 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!

* 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.

* 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.

This commit: Implements CPU Interrupts, Replaces Cycle Timing for Host
Timing, Reworks the Kernel's Scheduler, Introduce Idle State and
Suspended State, Recreates the bootmanager, Initializes Multicore
system.
Previously if applications would send faulty buffers(example homebrew) it would lead to us returning uninitalized data. Switching from ASSERT_MSG to ASSERT_OR_EXECUTE_MSG allows us to have a fail safe to prevent crashes but also continue execution without introducing undefined behavior
GetTotalPhysicalMemoryAvailableWithoutSystemResource & GetTotalPhysicalMemoryUsedWithoutSystemResource seem to subtract the resource size from the usage.
While èis generally representable in some language encodings, in some
it isn't and will result in compilation warnings occurring. To remain
friendly with other language's codepages on Windows, we normalize it to
an ASCII e.
We can also allow unicorn to be constructed in 32-bit mode or 64-bit
mode to satisfy the need for both interpreter instances.
Allows this code to compile successfully of non x86-64 architectures.
Any time the lambda function is called, the permission being used in the
capture would be passed in as an argument to the lambda, so the capture
is unnecessary.
These were added in the change that enabled -Wextra on linux builds so
as not to introduce interface changes in the same change as a
build-system flag addition.
Now that the flags are enabled, we can freely change the interface to
make these unnecessary.
Allows reporting more cases where logic errors may exist, such as
implicit fallthrough cases, etc.
We currently ignore unused parameters, since we currently have many
cases where this is intentional (virtual interfaces).
While we're at it, we can also tidy up any existing code that causes
warnings. This also uncovered a few bugs as well.
This can result in silent logic bugs within code, and given the amount
of times these kind of warnings are caused, they should be flagged at
compile-time so no new code is submitted with them.
shared_ptr was used in 2d1984c20c due to a
misunderstanding of how the language generates move constructors and
move assignment operators.
If a destructor is user-provided, then the compiler won't generate the
move constructor and move assignment operators by default--they must be
explicitly opted into.
The reason for the compilation errors is due to the fact that the
language will fall back to attempting to use the copy constructor/copy
assignment operators if the respective move constructor or move
assignment operator is unavailable.
Given that we explicitly opt into them now, the the move constructor and
move assignment operators will be generated as expected.
This isn't used within the class, so it can be removed to simplify the
overall interface.
While we're in the same area, we can simplify a unique_ptr reset() call.
module._memory was already moved over to a new shared_ptr.
So code_memory_size was not increased at all.
This lowers the heap space and so saves a bit of memory, usually between 50 to 100 MB.
This fixes a regression of c0a01f3adc
* Kernel: Correct behavior of Address Arbiter threads.
This corrects arbitration threads to behave just like in Horizon OS.
They are added into a container and released according to what priority
they had when added. Horizon OS does not reorder them if their priority
changes.
* Kernel: Address Feedback.
Over the course of the changes to the kernel code, a few includes are no
longer necessary, particularly with the change over to std::shared_ptr
from Boost's intrusive_ptr.
These are fairly trivial to implement, we can just do nothing. This also
provides a spot for us to potentially dump out any relevant info in the
future (e.g. for debugging purposes with homebrew, etc).
While we're at it, we can also correct the names of both of these
supervisor calls.
This commit corrects an error in which a Core could remain with an
exclusive state after running, leaving space for possible race
conditions between changing cores.
Now that literally every other API function is converted over to the
Memory class, we can just move the file-local page table into the Memory
implementation class, finally getting rid of global state within the
memory code.
The Write functions are used slightly less than the Read functions,
which make these a bit nicer to move over.
The only adjustments we really need to make here are to Dynarmic's
exclusive monitor instance. We need to keep a reference to the currently
active memory instance to perform exclusive read/write operations.
With all of the trivial parts of the memory interface moved over, we can
get right into moving over the bits that are used.
Note that this does require the use of GetInstance from the global
system instance to be used within hle_ipc.cpp and the gdbstub. This is
fine for the time being, as they both already rely on the global system
instance in other functions. These will be removed in a change directed
at both of these respectively.
For now, it's sufficient, as it still accomplishes the goal of
de-globalizing the memory code.
Amends a few interfaces to be able to handle the migration over to the
new Memory class by passing the class by reference as a function
parameter where necessary.
Notably, within the filesystem services, this eliminates two ReadBlock()
calls by using the helper functions of HLERequestContext to do that for
us.
A fairly straightforward migration. These member functions can just be
mostly moved verbatim with minor changes. We already have the necessary
plumbing in places that they're used.
IsKernelVirtualAddress() can remain a non-member function, since it
doesn't rely on class state in any form.
Migrates all of the direct mapping facilities over to the new memory
class. In the process, this also obsoletes the need for memory_setup.h,
so we can remove it entirely from the project.
* core_timing: Use better reference tracking for EventType.
- Moves ownership of the event to the caller, ensuring we don't fire events for destroyed objects.
- Removes need for unique names - we won't be using this for save states anyways.
This commit ensures cond var threads act exactly as they do in the real
console. The original implementation uses an RBTree and the behavior of
cond var threads is that at the same priority level they act like a
FIFO.
This commit corrects the behavior of cancel synchronization when the
thread is running/ready and ensures the next wait is cancelled as it's
suppose to.
Uncovered a bug within Thread's SetCoreAndAffinityMask() where an
unsigned variable (ideal_core) was being compared against "< 0", which
would always be a false condition.
We can also get rid of an unused function (GetNextProcessorId) which contained a sign
mismatch warning.
- This does not actually seem to exist in the real kernel - games reset these automatically.

In case of redundant yields, the scheduler will now idle the core for
it's timeslice, in order to avoid continuously yielding the same thing
over and over.
This only encourages the use of the global system instance (which will
be phased out long-term). Instead, we use the direct system function
call directly to remove the appealing but discouraged short-hand.
If an unmapping operation fails, we shouldn't be decrementing the amount
of memory mapped and returning that the operation was successful. We
should actually be returning the error code in this case.
Avoids potentially expensive (depending on the size of the memory block)
allocations by reserving the necessary memory before performing both
insertions. This avoids scenarios where the second insert may cause a
reallocation to occur.
Avoids needing to read the same long sequence of code in both code
paths. Also makes it slightly nicer to read and debug, as the locals
will be able to be shown in the debugger.
This commit ensures that all backing memory allocated for the Guest CPU
is aligned to 256 bytes. This due to how gpu memory works and the heavy
constraints it has in the alignment of physical memory.
This was initially necessary when AArch64 JIT emulation was in its
infancy and all memory-related instructions weren't implemented.
Given the JIT now has all of these facilities implemented, we can remove
these functions from the CPU interface.
Prior to PR, Yuzu did not restore memory to RW-
on unmap of mirrored memory or unloading of NRO.
(In fact, in the NRO case, the memory was unmapped
instead of reprotected to --- on Load, so it was
actually lost entirely...)
This PR addresses that, and restores memory to RW-
as it should.
This fixes a crash in Super Smash Bros when creating
a World of Light save for the first time, and possibly
other games/circumstances.
This sets the DeviceMapped attribute for GPU-mapped memory blocks,
and prevents merging device mapped blocks. This prevents memory
mapped from the gpu from having its backing address changed by
block coalesce.
This implements svcMapPhysicalMemory/svcUnmapPhysicalMemory for Yuzu,
which can be used to map memory at a desired address by games since
3.0.0.
It also properly parses SystemResourceSize from NPDM, and makes
information available via svcGetInfo.
This is needed for games like Super Smash Bros. and Diablo 3 -- this
PR's implementation does not run into the "ASCII reads" issue mentioned
in the comments of #2626, which was caused by the following bugs in
Yuzu's memory management that this PR also addresses:
* Yuzu's memory coalescing does not properly merge blocks. This results
in a polluted address space/svcQueryMemory results that would be
impossible to replicate on hardware, which can lead to game code making
the wrong assumptions about memory layout.
* This implements better merging for AllocatedMemoryBlocks.
* Yuzu's implementation of svcMirrorMemory unprotected the entire
virtual memory range containing the range being mirrored. This could
lead to games attempting to map data at that unprotected
range/attempting to access that range after yuzu improperly unmapped
it.
* This PR fixes it by simply calling ReprotectRange instead of
Reprotect.
Prior to execution within a process beginning, the process establishes
its own TLS region for uses (as far as I can tell) related to exception
handling.
Now that TLS creation was decoupled from threads themselves, we can add
this behavior to our Process class. This is also good, as it allows us
to remove a stub within svcGetInfo, namely querying the address of that
region.
Provides a more accurate name for the memory region and also
disambiguates between the map and new map regions of memory, making it
easier to understand.
Handles the placement of the stack a little nicer compared to the
previous code, which was off in a few ways. e.g.
The stack (new map) region, shouldn't be the width of the entire address
space if the size of the region calculation ends up being zero. It
should be placed at the same location as the TLS IO region and also have
the same size.
In the event the TLS IO region contains a size of zero, we should also
be doing the same thing. This fixes our memory layout a little bit and
also resolves some cases where assertions can trigger due to the memory
layout being incorrect.
Extracts out all of the thread local storage management from thread
instances themselves and makes the owning process handle the management
of the memory. This brings the memory management slightly more in line
with how the kernel handles these allocations.
Furthermore, this also makes the TLS page management a little more
readable compared to the lingering implementation that was carried over
from Citra.
This will be necessary for making our TLS slot management slightly more
straightforward. This can also be utilized for other purposes in the
future.
We can implement the existing simpler overload in terms of this one
anyways, we just pass the beginning and end of the ASLR region as the
boundaries.
The old implementation had faulty Threadsafe methods where events could
be missing. This implementation unifies unsafe/safe methods and makes
core timing thread safe overall.
This is performing more work than would otherwise be necessary during
VMManager's destruction. All we actually want to occur in this scenario
is for any allocated memory to be freed, which will happen automatically
as the VMManager instance goes out of scope.
Anything else being done is simply unnecessary work.
Given we don't currently implement the personal heap yet, the existing
memory querying functions are essentially doing what the memory querying
types introduced in 6.0.0 do.
So, we can build the necessary machinery over the top of those and just
use them as part of info types.
