Given we don't currently implement the personal heap yet, the existing
memory querying functions are essentially doing what the memory querying
types introduced in 6.0.0 do.
So, we can build the necessary machinery over the top of those and just
use them as part of info types.
Previously, the code was accumulating data into a std::vector and then
tossing all of it away if a setting was disabled.
Instead, we can just check if it's disabled and do no work at all if
possible. If it's enabled, then we can append to the vector and
allocate.
Unlikely to impact usage much, but it is slightly less sloppy with
resources.
A few of the aoc service stubs/implementations weren't fully popping all
of the parameters passed to them. This ensures that all parameters are
popped and, at minimum, logged out.
These are only used from within this translation unit, so they don't
need to have external linkage. They were intended to be marked with this
anyways to be consistent with the other service functions.
Renames the members to more accurately indicate what they signify.
"OneShot" and "Sticky" are kind of ambiguous identifiers for the reset
types, and can be kind of misleading. Automatic and Manual communicate
the kind of reset type in a clearer manner. Either the event is
automatically reset, or it isn't and must be manually cleared.
The "OneShot" and "Sticky" terminology is just a hold-over from Citra
where the kernel had a third type of event reset type known as "Pulse".
Given the Switch kernel only has two forms of event reset types, we
don't need to keep the old terminology around anymore.
This reduces the boilerplate that services have to write out the current thread explicitly. Using current thread instead of client thread is also semantically incorrect, and will be a problem when we implement multicore (at which time there will be multiple current threads)
This corrects cases where it was possible to write more entries into the
write buffer than were requested. Now, we check the size of the buffer
before actually writing into them.
We were also returning the wrong value for
GetAvailableLanguageCodeCount2(). This was previously returning 64, but
only 17 should have been returned. 64 entries is the size of the static
array used in MakeLanguageCode() within the service binary itself, but
isn't the actual total number of language codes present.
Also introduced in REV5 was a variable-size audio command buffer. This
also affects how the size of the work buffer should be determined, so we
can add handling for this as well.
Thankfully, no other alterations were made to how the work buffer size
is calculated in 7.0.0-8.0.0. There were indeed changes made to to how
some of the actual audio commands are generated though (particularly in
REV7), however they don't apply here.
Introduced in REV5. This is trivial to add support for, now that
everything isn't a mess of random magic constant values.
All this is, is a change in data type sizes as far as this function
cares.
"Unmagics" quite a few magic constants within this code, making it much
easier to understand. Particularly given this factors out specific
sections into their own self-contained lambda functions.
These are actually quite important indicators of thread lifetimes, so
they should be going into the debug log, rather than being treated as
misc info and delegated to the trace log.
Makes the code much nicer to follow in terms of behavior and control
flow. It also fixes a few bugs in the implementation.
Notably, the thread's owner process shouldn't be accessed in order to
retrieve the core mask or ideal core. This should be done through the
current running process. The only reason this bug wasn't encountered yet
is because we currently only support running one process, and thus every
owner process will be the current process.
We also weren't checking against the process' CPU core mask to see if an
allowed core is specified or not.
With this out of the way, it'll be less noisy to implement proper
handling of the affinity flags internally within the kernel thread
instances.
