Lioncash fbb82e61e3 kernel/hle_ipc: Convert std::shared_ptr IPC header instances to std::optional
There's no real need to use a shared lifetime here, since we don't
actually expose them to anything else. This is also kind of an
unnecessary use of the heap given the objects themselves are so small;
small enough, in fact that changing over to optionals actually reduces
the overall size of the HLERequestContext struct (818 bytes to 808
bytes).

Lioncash 221613d4ea kernel/server_session: Make data members private
Makes it much nicer to locally reason about server session behavior, as
part of its functionality isn't placed around other classes.

Lioncash 7526b6fce3 kernel/client_session: Make data members private
These can be made private, as they aren't accessed in contexts that
require them to be public.

Lioncash c161389a0f kernel/address_arbiter: Pass in system instance to constructor
Allows getting rid of reliance on the global accessor functions and
instead operating on the provided system instance.

Lioncash ec6664f6d6 kernel/address_arbiter: Convert the address arbiter into a class
Places all of the functions for address arbiter operation into a class.
This will be necessary for future deglobalizing efforts related to both
the memory and system itself.

Lioncash 79f970e6de kernel/thread: Remove obsolete TODO in Create()
This is a TODO carried over from Citra that doesn't apply here.

Lioncash 02bc9e9de1 core/hle/ipc: Remove unnecessary includes
Removes a few inclusion dependencies from the headers or replaces
existing ones with ones that don't indirectly include the required
headers.

This allows removing an inclusion of core/memory.h, meaning that if the
memory header is ever changed in the future, it won't result in
rebuilding the entirety of the HLE services (as the IPC headers are used
quite ubiquitously throughout the HLE service implementations).

Lioncash 40de7f6fe8 vm_manager: Use range helpers in HeapAlloc() and HeapFree()

Lioncash 6c42a23550 vm_manager: Provide address range checking functions for other memory regions

regions.

Lioncash fad20213e6 kernel/scheduler: Pass in system instance in constructor
Avoids directly relying on the global system instance and instead makes
an arbitrary system instance an explicit dependency on construction.

This also allows removing dependencies on some global accessor functions
as well.

Lioncash f59040d752 kernel/shared_memory: Get rid of the use of global accessor functions within Create()
Given we already pass in a reference to the kernel that the shared
memory instance is created under, we can just use that to check the
current process, rather than using the global accessor functions.

This allows removing direct dependency on the system instance entirely.

Lioncash 0be8fffc99 svc: Migrate address range checking functions to VMManager
Provides a bit of a more proper interface for these functions.

Lioncash d29f9e9709 kernel/handle_table: Make local variables as const where applicable
Makes immutable state explicit.
2019-02-25 11:12:38 -05:00
Lioncash 5167d1577d kernel/handle_table: Allow process capabilities to limit the handle table size
The kernel allows restricting the total size of the handle table through
the process capability descriptors. Until now, this functionality wasn't
hooked up. With this, the process handle tables become properly restricted.

In the case of metadata-less executables, the handle table will assume
the maximum size is requested, preserving the behavior that existed
before these changes.

Lioncash 4f8cd74061 kernel/handle-table: In-class initialize data members
Directly initializes members where applicable.

Lioncash 0220862ba5 kernel/handle_table: Resolve truncation warnings
Avoids implicit truncation warnings from u32 -> u16 (the truncation is
desirable behavior here).

Lioncash 0113c36300 address_arbiter: Use nested namespaces where applicable
A fairly trivial change. Other sections of the codebase use nested
namespaces instead of separate namespaces here. This one must have just
been overlooked.

Lioncash bd983414f6 core_timing: Convert core timing into a class
Gets rid of the largest set of mutable global state within the core.
This also paves a way for eliminating usages of GetInstance() on the
System class as a follow-up.

Note that no behavioral changes have been made, and this simply extracts
the functionality into a class. This also has the benefit of making
dependencies on the core timing functionality explicit within the
relevant interfaces.
2019-02-15 21:50:25 -05:00
Lioncash 48d9d66dc5 core_timing: Rename CoreTiming namespace to Core::Timing
Places all of the timing-related functionality under the existing Core
namespace to keep things consistent, rather than having the timing
utilities sitting in its own completely separate namespace.

Lioncash 414cc1eb1f kernel: Remove the Timer class
A holdover from citra, the Horizon kernel on the switch has no
prominent kernel object that functions as a timer. At least not
to the degree of sophistication that this class provided.

As such, this can be removed entirely. This class also wasn't used at
all in any meaningful way within the core, so this was just code sitting
around doing nothing. This also allows removing a few things from the
main KernelCore class that allows it to use slightly less resources
overall (though very minor and not anything really noticeable).

Lioncash a3cdd773c3 kernel/wait_object: Devirtualize functions related to manipulating the thread list directly
No inheritors of the WaitObject class actually make use of their own
implementations of these functions, so they can be made non-virtual.

It's also kind of sketchy to allow overriding how the threads get added
to the list anyways, given the kernel itself on the actual hardware
doesn't seem to customize based off this.

Lioncash 4596ef5274 kernel/timer: Remove unnecessary WakeupAllWaitingThreads() override
This implementation just calls the base class variant of the function,
so this isn't necessary.

Lioncash 1a302d4d47 kernel/readable_event: Remove unnecessary WakeupAllWaitingThreads() override

kernel/svc: Log out uncaught C++ exceptions from svcBreak
Looking into the implementation of the C++ standard facilities that seem
to be within all modules, it appears that they use 7 as a break reason
to indicate an uncaught C++ exception.

This was primarily found via the third last function called within
Horizon's equivalent of libcxxabi's demangling_terminate_handler(),
which passes the value 0x80000007 to svcBreak.

Lioncash b4242633ad kernel/svc: Correct misleading error message within CreateThread()
This is a bounds check to ensure that the thread priority is within the
valid range of 0-64. If it exceeds 64, that doesn't necessarily mean
that an actual priority of 64 was expected (it actually means whoever
called the function screwed up their math).

Instead clarify the message to indicate the allowed range of thread
priorities.

Lioncash 3a8d38be7e kernel/svc: Sanitize core number and thread priorities in CreateThread()
Now that we handle the kernel capability descriptors we can correct
CreateThread to properly check against the core and priority masks
like the actual kernel does.

Lioncash 8769604144 kernel/process: Rename GetAllowedProcessorMask() and GetAllowedThreadPriorityMask()

Lioncash 205e6d3b97 kernel/svc: Simplify thread core ID sanitizing in CreateThread
Rather than use a switch here, this can be collapsed into a simple range
check, which is a little easier on the eyes.

Lioncash a81ff6f54c kernel/process: Start the main thread using the specified ideal core
This matches kernel behavior in that processes are started using their
specified ideal core, rather than always starting on core 0.

Lioncash f80bc712ea kernel: Rename 'default' CPU core to 'ideal' core
This makes the naming more closely match its meaning. It's just a
preferred core, not a required default core. This also makes the usages
of this term consistent across the thread and process implementations.
2018-12-27 21:48:49 -05:00
Lioncash 771431f625 kernel/thread: Move process thread initialization into process.cpp
This function isn't a general purpose function that should be exposed to
everything, given it's specific to initializing the main thread for a
Process instance.

Given that, it's a tad bit more sensible to place this within
process.cpp, which keeps it visible only to the code that actually needs
it.

Lioncash fbeaa330a3 kernel/process: Remove most allocation functions from Process' interface
In all cases that these functions are needed, the VMManager can just be
retrieved and used instead of providing the same functions in Process'
interface.

This also makes it a little nicer dependency-wise, since it gets rid of
cases where the VMManager interface was being used, and then switched
over to using the interface for a Process instance. Instead, it makes
all accesses uniform and uses the VMManager instance for all necessary
tasks.

All the basic memory mapping functions did was forward to the Process'
VMManager instance anyways.
