set: Amend return value of GetAvailableLanguageCodes()
|
|
This just returns the size of the language code buffer.
|
|
The return code should be 32-bit in size.

Kernel/SVC: Perform atomic accesses in SignalProcessWideKey as per the real kernel.

Avoids unnecessary construction of std::string instances where
applicable.

file_util: Use an enum class for GetUserPath()
|
|
This behaves quite similarly to the SubmitGPFIFO command. Referenced from Ryujinx.
Many thanks to @gdkchan for investigating this!

Instead of using an unsigned int as a parameter and expecting a user to
always pass in the correct values, we can just convert the enum into an
enum class and use that type as the parameter type instead, which makes
the interface more type safe.
We also get rid of the bookkeeping "NUM_" element in the enum by just
using an unordered map. This function is generally low-frequency in
terms of calls (and I'd hope so, considering otherwise would mean we're
slamming the disk with IO all the time) so I'd consider this acceptable
in this case.

CPU: Save and restore the TPIDR_EL0 system register on every context switch

Note that there's currently a dynarmic bug preventing this register from being written.

Allows pushing strongly-typed enum members without the need to always
cast them at the call sites.
Note that we *only* allow strongly-typed enums in this case. The reason
for this is that strongly typed enums have a guaranteed defined size, so
the size of the data being pushed is always deterministic. With regular
enums this can be a little more error-prone, so we disallow them.
This function simply uses the underlying type of the enum to determine
the size of the data. For example, if an enum is defined as:
enum class SomeEnum : u16 {
SomeEntry
};
if PushEnum(SomeEnum::SomeEntry); is called, then it will push a
u16-size amount of data.

HLE/ACC: Stub IManagerForApplication::GetAccountId to return an error.

audout_u/audren_u: Ensure null terminators are written out in ListAudioOutsImpl(), ListAudioDeviceName(), and GetActiveAudioDeviceName()
|
|
thread: Convert ThreadStatus into an enum class
|
|
And make IManagerForApplication::CheckAvailability always return false.
Returning a bogus id from GetAccountId causes games to crash on boot.
We should investigate this with a hwtest and either stub it properly or implement it.

interface/device name
std::string doesn't include the null-terminator in its data() + size()
range. This ensures that the null-terminator will also be written to the buffer
|
|
interface name
Uses a type that doesn't potentially dynamically allocate, and ensures
that the name of the interface is properly null-terminated when writing
it to the buffer.
|
|
Makes the thread status strongly typed, so implicit conversions can't
happen. It also makes it easier to catch mistakes at compile time.

With the new overload, we can simply pass the container directly.

The default username for now is "yuzu".
We should eventually allow the creation of users in the emulator and have the ability to modify their parameters.

on startup.
In IApplicationFunctions::PopLaunchParameter we tell the games that they were launched as user id 1.
|
|
We only emulate a single user id for now.

nvflinger: Emplace Display instances directly
|
|
This introduces a slightly more generic variant of WriteBuffer().
Notably, this variant doesn't constrain the arguments to only accepting
std::vector instances. It accepts whatever adheres to the
ContiguousContainer concept in the C++ standard library.
This essentially means, std::array, std::string, and std::vector can be
used directly with this interface. The interface no longer forces you to
solely use containers that dynamically allocate.
To ensure our overloads play nice with one another, we only enable the
container-based WriteBuffer if the argument is not a pointer, otherwise
we fall back to the pointer-based one.

nvdrv: Take std::string by const reference in GetDevice()
|
|
Filesystem: Return EntryType::Directory for the root directory.
|
|
This WriteBuffer overload expects its size argument to be in bytes, not
elements.
|

The reason this would never be true is that ideal_processor is a u8 and
THREADPROCESSORID_DEFAULT is an s32. In this case, it boils down to how
arithmetic conversions are performed before performing the comparison.
If an unsigned value has a lesser conversion rank (aka smaller size)
than the signed type being compared, then the unsigned value is promoted
to the signed value (i.e. u8 -> s32 happens before the comparison). No
sign-extension occurs here either.
An alternative phrasing:
Say we have a variable named core and it's given a value of -2.
u8 core = -2;
This becomes 254 due to the lack of sign. During integral promotion to
the signed type, this still remains as 254, and therefore the condition
will always be true, because no matter what value the u8 is given it
will never be -2 in terms of 32 bits.
Now, if one type was a s32 and one was a u32, this would be entirely
different, since they have the same bit width (and the signed type would
be converted to unsigned instead of the other way around) but would
still have its representation preserved in terms of bits, allowing the
comparison to be false in some cases, as opposed to being true all the
time.

We also get rid of two signed/unsigned comparison warnings while we're
at it.

GetSharedFontInOrderOfPriority()
This can just use the fmt specifiers and be type-agnostic.
|
|
hle_ipc: Amend usage of buffer_index within one of HLERequestContext's WriteBuffer() overloads
|
|
fsp_srv: Misc individual changes
|
|
Modernizes the loops themselves while also getting rid of a signed/unsigned
comparison in a loop condition.
|
|
Gets rid of the use of a magic constant
|
|
It is unknown if this is correct behavior, but it makes sense and fixes a regression with Stardew Valley.
|
|
Prevents implicit construction and makes these lingering non-explicit
constructors consistent with the rest of the other classes in services.
|
|
We can use emplace_back to construct the Display instances directly,
instead of constructing them separately and copying them, avoiding the
need to copy std::string and std::vector instances that are part of the
Display struct.
|
|
This is only ever used as a lookup into the device map, so we don't need to
take the std::string instance by value here.
|
|
WriteBuffer() overloads
Previously, the buffer_index parameter was unused, causing all writes to
use the buffer index of zero, which is not necessarily what is wanted
all the time.
Thankfully, all current usages don't use a buffer index other than zero,
so this just prevents a bug before it has a chance to spring.
|
|
We can avoid constructing a std::vector here by simply passing a pointer
to the original data and the size of the copy we wish to perform to the
backend's Write() function instead, avoiding copying the data where it's
otherwise not needed.
