- This checks for and removes old updates or dlc based on title id. If a content meta nca exists within the registered cache, it will attempt to remove all the ncas associated with the content meta before installing a new update/dlc
When zero byte files are present, the key (offset) for that file is identical to the file right after. A std::map isn't able to fit key-value pairs with identical keys (offsets), therefore, the solution is to use std::multimap which permits multiple entries with the same key.
This most prominently fixes Pokemon Sword and Shield weather with any RomFS mod applied.
The file wasn't closed prior to being renamed / moved, throwing an error that states "The process cannot access the file because it is being used by another process." Fix this by closing the file prior to a rename / move operation.
Fixes saving in Luigi's Mansion 3 and KATANA KAMI: A Way of the Samurai Story.
We should not be limited by the SDMC's partition size, set this to 1 TiB. Hardware is limited to the max allowed by the MBR partition table which is 2 TiB.
Sets the total space of user and system partitions to their hardware defaults.
Furthermore, return the total space as free space for the user partition to prevent it from reaching zero.
Some games like Bioshock 2 check for the available free space prior to save creation, and we should not be limited by arbitrary limits.
Changes many patch_manager functions to use a case-less variant of
GetSubdirectory. Fixes patches not showing up on *nix systems when
patch directories are named with odd cases, i.e. `exeFS'.
Previously, we were reading the keys everytime a KeyManager object was created, causing yuzu to reread the keys file multiple hundreds of times when loading the game list.
With this change, it is only loaded once.
On my system, this decreased game list loading times by a factor of 20.
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.
After further hardware investigation, it appears that some games, perhaps those more lazily coded, will not call EnsureSaveData, meaning that they expect the normal (current) save to be automatically made. Additionally, some games do not create a cache or temporary save before use.
In these 3 specific instances, the save is created automatically for the game if it doesn't exist.
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.
Migrates the HLE service code off the use of directly accessing the
global system instance where trivially able to do so.
This removes all usages of Core::CurrentProcess from the service code,
only 8 occurrences of this function exist elsewhere. There's still quite
a bit of "System::GetInstance()" being used, however this was able to
replace a few instances.
This is to go with the Atmosphere VM port, now it just contains the callbacks needed for the interface between DmntCheatVm and yuzu, along with the cheat parsers.
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.
DeltaFragments are only used to download and apply partial patches on a real console, and are not useful to us at all. Most patch NSPs do not include them, and when they do, it's a waste of space to install them.
IPC-100 was changed to InitializeApplicationInfoOld instead of InitializeApplicationInfo. IPC-150 makes an indentical call to IPC-100 however does extra processing. They should not have the same name as it's quite confusing to debug.
These can be generified together by using a concept type to designate
them. This also has the benefit of not making copies of potentially very
large arrays.
BitField has been trivially copyable since
e99a148628, so we can eliminate these
TODO comments and use ReadObject() directly instead of memcpying the
data.
Quite a bit of these were out of sync with Switchbrew (and in some cases
entirely wrong). While we're at it, also expand the section of named
members. A segment within the control metadata is used to specify
maximum values for the user, device, and cache storage max sizes and
journal sizes.
These appear to be generally used by the am service (e.g. in
CreateCacheStorage, etc).
This source file was utilizing its own version of the NSO header.
Instead of keeping this around, we can have the patch manager also use
the version of the header that we have defined in loader/nso.h
Provides extra information that makes it easier to tell if an executable
being run is using a 36-bit address space or a 39-bit address space.
While we don't support AArch32 executables yet, this also puts in
distinguishing information for the 32-bit address space types as well.
This stores a file in the save directory called '.yuzu_save_size' which stores the two save sizes (normal area and journaled area) sequentially as u64s.
fmt::format() returns a std::string instance by value, so calling
.c_str() on it here is equivalent to doing:
auto* ptr = std::string{}.c_str();
The data being pointed to isn't guaranteed to actually be valid anymore
after that expression ends. Instead, we can just take the string as is,
and provide the necessary formatting parameters.
Amends it with missing values deduced from RE (ProperSystem being from
SwitchBrew for naming)
(SdCardUser wasn't that difficult to discern given it's used alongside
SdCardSystem when creating the save data indexer, based off the usage of
the string "saveDataIxrDbSd" nearby).
This allows the array to be constexpr. std::function is also allowed to
allocate memory, which makes its constructor non-trivial, we definitely
don't want to have all of these execute at runtime, taking up time
before the application can actually load.
We can just return a new instance of this when it's requested. This only
ever holds pointers to the existing registed caches, so it's not a large
object. Plus, this also gets rid of the need to keep around a separate
member function just to properly clear out the union.
Gets rid of one of five globals in the filesystem code.
This is the same behavior-wise as DeleteDirectoryRecursively, with the
only difference being that it doesn't delete the top level directory in
the hierarchy, so given:
root_dir/
- some_dir/
- File.txt
- OtherFile.txt
The end result is just:
root_dir/
These parameters don't need to utilize a shared lifecycle directly in
the interface. Instead, the caller should provide a regular reference
for the function to use. This also allows the type system to flag
attempts to pass nullptr and makes it more generic, since it can now be
used in contexts where a shared_ptr isn't being used (in other words, we
don't constrain the usage of the interface to a particular mode of
memory management).
While we're at it, organize the array linearly, since clang formats the
array elements quite wide length-wise with the addition of the missing
'u'.
Technically also fixes patch lookup and icon lookup with Portuguese,
though I doubt anyone has actually run into this issue.
The decision was made to name them LayeredExeFS instead of just LayeredFS to differentiate from normal RomFS-based mods. The name may be long/unweildy, but conveys the meaning well.
This will scan the <mod>/exefs dir for all files and then layer those on top of the game's exefs and use this as the new exefs. This allows for overriding of the compressed NSOs or adding new files. This does use the same dir as IPS/IPSwitch patch, but since the loader will not look for those they are ignored.
There's no real point to keeping the separate enum around, especially
given the name of the error code itself is supposed to document what the
value actually represents.
Allows resuing a common KeyManager when a large amount of NCAs are handled by the same class. Should the parameter not be provided, a new KeyManager will be constructed, as was the default behavior prior to this.
* get rid of boost::optional
* Remove optional references
* Use std::reference_wrapper for optional references
* Fix clang format
* Fix clang format part 2
* Adressed feedback
* Fix clang format and MacOS build
Returns the raw NACP bytes and the raw icon bytes into a title-provided buffer. Pulls from Registration Cache for control data, returning all zeros should it not exist.
When enabled in settings, PatchNSO will dump the unmodified NSO that it was passed to a file named <build id>.nso in the dump root for the current title ID.
When writing VFS, it initally seemed useful to include a function to in-place convert container files into directories in one homogenous directory structure, but re-evaluating it now there have been plenty of chances to use it and there has always been a better way. Removing as it is unused and likely will not be used.
The constructor alone is pretty large, the reading code should be split
into its consistuent parts to make it easier to understand it without
having to build a mental model of a 300+ line function.
The only reason the getter existed was to check whether or not the
program NCA was null. Instead, we can just provide a function to query
for the existence of it, instead of exposing it entirely.
The data retrieved in these cases are ultimately chiefly owned by either
the RegisteredCache instance itself, or the filesystem factories. Both
these should live throughout the use of their contained data. If they
don't, it should be considered an interface/design issue, and using
shared_ptr instances here would mask that, as the data would always be
prolonged after the main owner's lifetime ended.
This makes the lifetime of the data explicit and makes it harder to
accidentally create cyclic references. It also makes the interface
slightly more flexible than the previous API, as a shared_ptr can be
created from a unique_ptr, but not the other way around, so this allows
for that use-case if it ever becomes necessary in some form.
Neither of these functions require the use of shared ownership of the
returned pointer. This makes it more difficult to create reference
cycles with, and makes the interface more generic, as std::shared_ptr
instances can be created from a std::unique_ptr, but the vice-versa
isn't possible. This also alters relevant functions to take NCA
arguments by const reference rather than a const reference to a
std::shared_ptr. These functions don't alter the ownership of the memory
used by the NCA instance, so we can make the interface more generic by
not assuming anything about the type of smart pointer the NCA is
contained within and make it the caller's responsibility to ensure the
supplied NCA is valid.
We can just compare the existing std::vector instance with a constexpr
std::array containing the desired match. This is lighter resource-wise,
as we don't need to allocate on the heap.
