In some games (Splatoon 2 and Splatoon 2 Splatfest World Premiere, notably), pass offset=0 and count=2047 into the ListAddOnContent method which should return all DLCs for the current title. The (presumably) intended behavior is to successfully return a empty array but because of a < v. <= in an if statement, a failure error code was returned causing these games to svcBreak. This fixes that if statement.

Adds new functions that have been given names to the table. Information
is based off what is provided on Switchbrew.

Amends the lbl service table to include new names of functions that were
added to Switchbrew.

Avoid resource-heavy classes and remove quasi-duplicated code.

While PatchExeFS operated on the entire directory, this function operates on the uncompressed NSO. Avoids copying decompression code to PatchManager.

Previous behavior was to assert. Seems to mirror expected game behavior.

Implement ISystemDisplayService::GetDisplayMode
|
|
Now that we have all of the rearranging and proper structure sizes in
place, it's fairly trivial to implement svcGetThreadContext(). In the
64-bit case we can more or less just write out the context as is, minus
some minor value sanitizing. In the 32-bit case we'll need to clear out
the registers that wouldn't normally be accessible from a 32-bit
AArch32 exectuable (or process).
|
|
This will be necessary for the implementation of svcGetThreadContext(),
as the kernel checks whether or not the process that owns the thread
that has it context being retrieved is a 64-bit or 32-bit process.
If the process is 32-bit, then the upper 15 general-purpose registers
and upper 16 vector registers are cleared to zero (as AArch32 only has
15 GPRs and 16 128-bit vector registers. not 31 general-purpose
registers and 32 128-bit vector registers like AArch64).
|
|
Makes the public interface consistent in terms of how accesses are done
on a process object. It also makes it slightly nicer to reason about the
logic of the process class, as we don't want to expose everything to
external code.
|
|
Internally within the kernel, it also includes a member variable for the
floating-point status register, and TPIDR, so we should do the same here to match
it.
While we're at it, also fix up the size of the struct and add a static
assertion to ensure it always stays the correct size.

a SharedPtr
A process should never require being reference counted in this
situation. If the handle to a process is freed before this function is
called, it's definitely a bug with our lifetime management, so we can
put the requirement in place for the API that the process must be a
valid instance.

kernel/object: Remove unnecessary std::move from DynamicObjectCast()
|
|
process/vm_manager: Initial modifications to load NPDM metadata
|
|
boost::static_pointer_cast for boost::intrusive_ptr (what SharedPtr is),
takes its parameter by const reference. Given that, it means that this
std::move doesn't actually do anything other than obscure what the
function's actual behavior is, so we can remove this. To clarify, this
would only do something if the parameter was either taking its argument
by value, by non-const ref, or by rvalue-reference.

stream: Preserve enum class type in GetState()
|
|
FPCR register was uninitialized at start up
|
|
Avoids making copies of large std::vector instances where it's trivially
avoidable to do so.
|
|
Theres no need to do explicit bitwise arithmetic here, when we have a
function that does this with a more descriptive name.

|
kernel/scheduler: Take ARM_Interface instances by reference
|
|
service: Add missing headers inclusions where applicable
|
|
Avoids the need to nest code quite a bit by early-exiting in error
cases.
|
|
initializer list
Orders the initializer list members to be in the same order that they
would be initialized in. Avoids compiler warnings.
|
|
Cast where explicitly necessary and in other cases we can simply modify
the algorithm to accomodate larger data.
|
|
RomFSBuildFileContext and RomFSBuildDirectoryContext
There's no need to duplicate in-class initializers with a constructor
initializer list. std::strings also initialize to empty by default.
|
|
The std::vector instances are already initially allocated with all
entries having these values, there's no need to loop through and fill
them with it again when they aren't modified.
|
|
auto x = 0;
auto-deduces x to be an int. This is undesirable when working with
unsigned values. It also causes sign conversion warnings. Instead, we
can make it a proper unsigned value with the correct width that the
following expressions operate on.
|
|
Given we just recently had a patch backport this from citra, let's try
and keep the convention uniform.
|
|
Given these are only added to the class to allow those functions to
access the private constructor, it's a better approach to just make them
static functions in the interface, to make the dependency explicit.
|
|
This converts it into a regular constructor parameter. There's no need
to make this a template parameter on the class when it functions
perfectly well as a constructor argument.
This also reduces the amount of code bloat produced by the compiler, as
it doesn't need to generate the same code for multiple different
instantiations of the same class type, but with a different fill value.
|
|
Gets rid of a few indirect inclusions.

|
file_sys: Add support for LayeredFS mods
|
|
This is only exposed by reference, so we can just make it a unique
pointer to get rid of the need to also use reference counting for the
pointer.
|
|
It doesn't make sense to allow a scheduler to be constructed around a
null pointer.

|
svc: Updated svc names
|
|
The locations of these can actually vary depending on the address space
layout, so we shouldn't be using these when determining where to map
memory or be using them as offsets for calculations. This keeps all the
memory ranges flexible and malleable based off of the virtual memory
manager instance state.
