- Fixes a circular dependency which prevented threads from being released on shutdown.
|
|
|
|
With this, the kernel finally doesn't depend directly on the global
system instance anymore.
|
|
- helpful to disambiguate Kernel::Memory namespace.

reflect RE.

|
|
Amends a few interfaces to be able to handle the migration over to the
new Memory class by passing the class by reference as a function
parameter where necessary.
Notably, within the filesystem services, this eliminates two ReadBlock()
calls by using the helper functions of HLERequestContext to do that for
us.

kernel objects. (#3154)
* kernel: Replace usage of boost::intrusive_ptr with std::shared_ptr for kernel objects.
- See https://github.com/citra-emu/citra/pull/4710 for details.
|
|
Some objects declare their handle type as const, while others declare it
as constexpr. This makes the const ones constexpr for consistency, and
prevent unexpected compilation errors if these happen to be attempted to be
used within a constexpr context.
|
|
Keeps the return type consistent with the function name. While we're at
it, we can also reduce the amount of boilerplate involved with handling
these by using structured bindings.

kernel/server_session: Provide a GetName() override
|
|
Given server sessions can be given a name, we should allow retrieving
it instead of using the default implementation of GetName(), which would
just return "[UNKNOWN KERNEL OBJECT]".
|
|
Given this is intended as a querying function, it doesn't make sense to
allow the implementer to modify the state of the given thread.
|
|
Makes it much nicer to locally reason about server session behavior, as
part of its functionality isn't placed around other classes.
|
|
Gets rid of a few unnecessary header dependencies in some source files.
|
|
As means to pave the way for getting rid of global state within core,
This eliminates kernel global state by removing all globals. Instead
this introduces a KernelCore class which acts as a kernel instance. This
instance lives in the System class, which keeps its lifetime contained
to the lifetime of the System class.
This also forces the kernel types to actually interact with the main
kernel instance itself instead of having transient kernel state placed
all over several translation units, keeping everything together. It also
has a nice consequence of making dependencies much more explicit.
This also makes our initialization a tad bit more correct. Previously we
were creating a kernel process before the actual kernel was initialized,
which doesn't really make much sense.
The KernelCore class itself follows the PImpl idiom, which allows
keeping all the implementation details sealed away from everything else,
which forces the use of the exposed API and allows us to avoid any
unnecessary inclusions within the main kernel header.
|
|
Allows querying the inverse of IsDomain() to make things more readable.
This will likely also be usable in the event of implementing
ConvertDomainToSession().
|
|
General moving to keep kernel object types separate from the direct
kernel code. Also essentially a preliminary cleanup before eliminating
global kernel state in the kernel code.
|
|
Removes unnecessary direct dependencies in some headers and also gets
rid of indirect dependencies that were being relied on to be included.

starvation.
Ported from citra PR #3091
The delay specified here is from a Nintendo 3DS, and should be measured in a Nintendo Switch.
This change is enough to prevent Puyo Puyo Tetris's main thread starvation.

This allows attaching a HLE handle to a ServerPort at any point after it
is created, allowing port/session creation to be generic between HLE and
regular services.
|
|
Most of the code that works with this is or will be in the kernel, so
it's a more appropriate place for it to be.
|
|
|
|
Now that HandleTable doesn't directly depend on WaitObject anymore, this
can be separated from the main kernel.h header.

session pair.
Reduce the associated port's connection count when a ServerSession is destroyed.
|
|
Corrects a few issues with regards to Doxygen documentation, for example:
- Incorrect parameter referencing.
- Missing @param tags.
- Typos in @param tags.
and a few minor other issues.

This will be useful when implementing mutex priority inheritance.

ServerSessions created from it.
|
|
|
|
Sessions and Ports are now detached from each other.
HLE services are handled by means of a SessionRequestHandler class, Interface now inherits from this class.
The File and Directory classes are no longer kernel objects, but SessionRequestHandlers instead, bound to a ServerSession when requested.
File::OpenLinkFile now creates a new session pair and binds the File instance to it.

Inter Process Communication.
All handles obtained via srv::GetServiceHandle or svcConnectToPort are references to ClientSessions.
Service modules will wait on the counterpart of those ClientSessions (Called ServerSessions) using svcReplyAndReceive or svcWaitSynchronization[1|N], and will be awoken when a SyncRequest is performed.
HLE Interfaces are now ClientPorts which override the HandleSyncRequest virtual member function to perform command handling immediately.
