kernel/codeset: Make CodeSet's memory data member a regular std::vector

Lioncash 781ab8407b general: Use deducation guides for std::lock_guard and std::unique_lock
Since C++17, the introduction of deduction guides for locking facilities
means that we no longer need to hardcode the mutex type into the locks
themselves, making it easier to switch mutex types, should it ever be
necessary in the future.

Merge pull request #2304 from lioncash/memsize
kernel/process: Report total physical memory used to svcGetInfo slightly better

Lioncash 824b8e4086 kernel/scheduler: Remove unused parameter to AddThread()
This was made unused in b404fcdf14, but
the parameter itself wasn't removed.

Lioncash cb805f45ae kernel/scheduler: Use deduction guides on mutex locks
Since C++17, we no longer need to explicitly specify the type of the
mutex within the lock_guard. The type system can now deduce these with
deduction guides.

Lioncash 3a846aa80f kernel/process: Report total physical memory used to svcGetInfo
Reports the (mostly) correct size through svcGetInfo now for queries to
total used physical memory. This still doesn't correctly handle memory
allocated via svcMapPhysicalMemory, however, we don't currently handle
that case anyways.

Lioncash 2289e895aa kernel/process: Store the total size of the code memory loaded

Lioncash 427f1e3e3d kernel/process: Make Run's stack size parameter a u64
This will make operating with the process-related SVC commands much
nicer in the future (the parameter representing the stack size in
svcStartProcess is a 64-bit value).

Lioncash 2aca7b9e1e kernel/process: Ensure that given stack size is always page-aligned
The kernel always makes sure that the given stack size is aligned to
page boundaries.

core/core_timing: Make callback parameters consistent
2019-03-25 21:06:33 -04:00
Lioncash c5d41fd812 core/core_timing: Make callback parameters consistent
In some cases, our callbacks were using s64 as a parameter, and in other
cases, they were using an int, which is inconsistent.

To make all callbacks consistent, we can just use an s64 as the type for
late cycles, given it gets rid of the need to cast internally.

While we're at it, also resolve some signed/unsigned conversions that
were occurring related to the callback registration.

Lioncash bd7ec1a749 kernel/kernel: Remove unnecessary forward declaration
This is no longer necessary, as ResultVal isn't used anywhere in the
header.

Lioncash 7c4bc7b883 kernel/process: Remove unused AddressMapping struct
Another leftover from citra that's now no longer necessary.

Lioncash 1e92ba2785 kernel/vm_manager: Handle shrinking of the heap size within SetHeapSize()
One behavior that we weren't handling properly in our heap allocation
process was the ability for the heap to be shrunk down in size if a
larger size was previously requested.

This adds the basic behavior to do so and also gets rid of HeapFree, as
it's no longer necessary now that we have allocations and deallocations
going through the same API function.

While we're at it, fully document the behavior that this function
performs.

Lioncash 99a163478b kernel/vm_manager: Rename HeapAllocate to SetHeapSize
Makes it more obvious that this function is intending to stand in for
the actual supervisor call itself, and not acting as a general heap
allocation function.

Also the following change will merge the freeing behavior of HeapFree
into this function, so leaving it as HeapAllocate would be misleading.
2019-03-24 17:08:30 -04:00
Lioncash abdb81ccaf kernel/vm_manager: Handle case of identical calls to HeapAllocate
In cases where HeapAllocate is called with the same size of the current
heap, we can simply do nothing and return successfully.

This avoids doing work where we otherwise don't have to. This is also
what the kernel itself does in this scenario.
2019-03-24 17:08:30 -04:00
Lioncash 9f63acac0f kernel/vm_manager: Remove unused class variables
Over time these have fallen out of use due to refactoring, so these can
be removed.
2019-03-24 17:08:30 -04:00
Lioncash 52980df1aa kernel/vm_manager: Remove unnecessary heap_used data member
This isn't required anymore, as all the kernel ever queries is the size
of the current heap, not the total usage of it.
2019-03-24 17:08:16 -04:00
Lioncash 586cab6172 kernel/vm_manager: Tidy up heap allocation code
Another holdover from citra that can be tossed out is the notion of the
heap needing to be allocated in different addresses. On the switch, the
base address of the heap will always be managed by the memory allocator
in the kernel, so this doesn't need to be specified in the function's
interface itself.

The heap on the switch is always allocated with read/write permissions,
so we don't need to add specifying the memory permissions as part of the
heap allocation itself either.

This also corrects the error code returned from within the function.
If the size of the heap is larger than the entire heap region, then the
kernel will report an out of memory condition.

Lioncash c0a01f3adc kernel/codeset: Make CodeSet's memory data member a regular std::vector
The use of a shared_ptr is an implementation detail of the VMManager
itself when mapping memory. Because of that, we shouldn't require all
users of the CodeSet to have to allocate the shared_ptr ahead of time.
It's intended that CodeSet simply pass in the required direct data, and
that the memory manager takes care of it from that point on.

This means we just do the shared pointer allocation in a single place,
when loading modules, as opposed to in each loader.

Lioncash 18918f5f2f kernel/vm_manager: Rename CodeStatic/CodeMutable to Code and CodeData respectively
Makes it more evident that one is for actual code and one is for actual
data. Mutable and static are less than ideal terms here, because
read-only data is technically not mutable, but we were mapping it with
that label.

Lioncash 56c80a2a21 kernel/vm_manager: Amend flag values for CodeMutable

Lioncash 1b6bd9d6df kernel: Move CodeSet structure to its own source files
Given this is utilized by the loaders, this allows avoiding inclusion of
the kernel process definitions where avoidable.

This also keeps the loading format for all executable data separate from
the kernel objects.

Lioncash c892cf01fa kernel/thread: Migrate WaitCurrentThread_Sleep into the Thread interface
Rather than make a global accessor for this sort of thing. We can make
