Lioncash f9951352f6 service/nvdrv: Take std::string in Open() by const reference 
Avoids copies from being made, since the string is only ever used for

Ideally, we'd use a std::string_view here, but devices is a
std::unordered_map, not a std::map, so we can't use heterogenous lookup
here.

 2018-07-21 15:50:02 -05:00
Lioncash d66b43dadf file_util: Use an enum class for GetUserPath() 
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.

Lioncash 0a0b3c4b9f ipc_helpers: Add PushEnum() member function to ResponseBuilder 
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.

Lioncash ff500a7b68 hle_ipc: Introduce generic WriteBuffer overload for multiple container types 
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.

Lioncash b879fb84a2 svc: Correct always true assertion case in SetThreadCoreMask 
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.

Lioncash af2698dcea hle_ipc: Amend usage of buffer_index within one of HLERequestContext's 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.

Lioncash 6c1ba02e0c fsp_srv: Remove unnecessary vector construction in IFile's Write() function

backend's Write() function instead, avoiding copying the data where it's
otherwise not needed.

Lioncash 3e9b79e088 fsp_srv: Remove unnecessary std::vector construction in IDirectory's Read() function 
We were using a second std::vector as a buffer to convert another
std::vector's data into a byte sequence, however we can just use
pointers to the original data and use them directly with WriteBuffer,
which avoids copying the data at all into a separate std::vector.

We simply cast the pointers to u8* (which is allowed by the standard,
given std::uint8_t is an alias for unsigned char on platforms that we
support).

Lioncash d6e9b96e2f fsp_srv: Respect write length in Write() 
Previously we were just copying the data whole-sale, even if the length
was less than the total data size. This effectively makes the
actual_data vector useless, which is likely not intended.

Instead, amend this to only copy the given length amount of data.

At the same time, we can avoid zeroing out the data before using it by
passing iterators to the constructor instead of a size.
