Rather than hard-code the address range to be 36-bit, we can derive the
parameters from supplied NPDM metadata if the supplied exectuable
supports it. This is the bare minimum necessary for this to be possible.
The following commits will rework the memory code further to adjust to
this.
* Implemented fatal:u properly
fatal:u now is properly implemented with all the ipc cmds. Error reports/Crash reports are also now implemented for fatal:u. Crash reports save to yuzu/logs/crash_reports/
The register dump is currently known as sysmodules send all zeros. If there are any non zero values for the "registers" or the unknown values, let me know!
* Fatal:U fixups
* Made fatal:u execution break more clear
* Fatal fixups
* Stubbed IRS
Currently we have no ideal way of implementing IRS. For the time being we should have the functions stubbed until we come up with a way to emulate IRS properly.
* Added IRS to logging backend
* Forward declared shared memory for irs
Preserves the meaning/type-safetiness of the stream state instead of
making it an opaque u32. This makes it usable for other things outside
of the service HLE context.
Even though setting this value to 3 is more correct. We break more games than we fix due to missing implementations. We should keep this as 0 for the time being
The owning process of a thread is required to exist before the thread,
so we can enforce this API-wise by using a reference. We can also avoid
the reliance on the system instance by using that parameter to access
the page table that needs to be set.
Several classes have a lot of non-trivial members within them, or don't
but likely should have the destructor defaulted in the cpp file for
future-proofing/being more friendly to forward declarations.
Leaving the destructor unspecified allows the compiler to inline the
destruction code all over the place, which is generally undesirable from
a code bloat perspective.
This was used in two different translation units
(deconstructed_rom_directory and patch_manager). This means we'd be
pointlessly duplicating the whole array twice due to it being defined
within the header.
These variables aren't used, which still has an impact, as std::vector
cannot be optimized away by the compiler (it's constructor and
destructor are both non-trivial), so this was just wasting memory.
std::shared_ptr isn't strictly necessary here and is only ever used in
contexts where the object doesn't depend on being shared. This also
makes the interface more flexible, as it's possible to create a
std::shared_ptr from a std::unique_ptr (std::shared_ptr has a
constructor that accepts a std::unique_ptr), but not the other way
around.
An instance of the NAX apploader already has an existing NAX instance in
memory. Calling directly into IdentifyType() directly would re-parse the
whole file again into yet another NAX instance, only to toss it away
again.
This gets rid of unnecessary/redundant file parsing and allocations.
AsNCA() allocates an NCA instance every time it's called. In the current
manner it's used, it's quite inefficient as it's making a redundant
allocation.
We can just amend the order of the conditionals to make it easier to
just call it once.
* Reworked incorrect nifm stubs
Need confirmation on `CreateTemporaryNetworkProfile`, unsure which game uses it but according to reversing. It should return a uuid which we currently don't do.
Any 0 client id is considered an invalid client id.
GetRequestState 0 is considered invalid.
* Fixups for nifm
* Fix bug where default username value for yuzu_cmd create an userprofile with uninitialize data as username
* Fix format
* Apply code review changes
* Remove nullptr check
This can just be a regular function, getting rid of the need to also
explicitly undef the define at the end of the file. Given FuncReturn()
was already converted into a function, it's #undef can also be removed.
Previously the second half of the value being written would overwrite
the first half. Thankfully this wasn't a bug that was being encountered,
as the function is currently unused.
This modifies the CPU interface to more accurately match an
AArch64-supporting CPU as opposed to an ARM11 one. Two of the methods
don't even make sense to keep around for this interface, as Adv Simd is
used, rather than the VFP in the primary execution state. This is
essentially a modernization change that should have occurred from the
get-go.
The kernel does the equivalent of the following check before proceeding:
if (address + 0x8000000000 < 0x7FFFE00000) {
return ERR_INVALID_MEMORY_STATE;
}
which is essentially what our IsKernelVirtualAddress() function does. So
we should also be checking for this.
The kernel also checks if the given input addresses are 4-byte aligned,
however our Mutex::TryAcquire() and Mutex::Release() functions already
handle this, so we don't need to add code for this case.

This also moves them into the cpp file and limits the visibility to
where they're directly used. It also gets rid of unused or duplicate
error codes.
The kernel caps the size limit of shared memory to 8589930496 bytes (or
(1GB - 512 bytes) * 8), so approximately 8GB, where every GB has a 512
byte sector taken off of it.
It also ensures the shared memory is created with either read or
read/write permissions for both permission types passed in, allowing the
remote permissions to also be set as "don't care".
Part of the checking done by the kernel is to check if the given
address and size are 4KB aligned, as well as checking if the size isn't
zero. It also only allows mapping shared memory as readable or
read/write, but nothing else, and so we shouldn't allow mapping as
anything else either.
Previously, these were sitting outside of the Kernel namespace, which
doesn't really make sense, given they're related to the Thread class
which is within the Kernel namespace.
There were a few places where nested namespace specifiers weren't being
used where they could be within the service code. This amends that to
make the namespacing a tiny bit more compact.
