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.

Allows games to log data to the SD.

Applies the override specifier where applicable. In the case of
destructors that are defaulted in their definition, they can
simply be removed.
This also removes the unnecessary inclusions being done in audin_u and
audrec_u, given their close proximity.
|
|
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.

Services created with the ServiceFramework base class install themselves as HleHandlers with an owning shared_ptr in the ServerPort ServiceFrameworkBase::port member variable, creating a cyclic ownership between ServiceFrameworkBase and the ServerPort, preventing deletion of the service objects.
Fix that by removing the ServiceFrameworkBase::port member because that was only used to detect multiple attempts at installing a port. Instead store a flag if the port was already installed to achieve the same functionality.

VfsFilesystem instance by reference
Neither of these functions alter the ownership of the provided pointer,
so we can simply make the parameters a reference rather than a direct
shared pointer alias. This way we also disallow passing incorrect memory values like
nullptr.
|
|
|
|
Now that we have a class representing the kernel in some capacity, we
now have a place to put the named port map, so we move it over and get
rid of another piece of global state within the core.
|
|
struct should be used when the data type is very simple or otherwise has
no invariants associated with it. Given these are used to form a
hierarchy, class should be used instead.
|
|
|
|
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.
|
|
Avoids unwanted implicit conversions. Thankfully, given the large amount
of cleanup in past PRs, only this tiny amount is left over to cover.

Converts the service manager from a global into an instance-based
variable.

The old "Interface" class had a few problems such as using free
functions (Which didn't allow you to write the service handler as if it
were a regular class.) which weren't very extensible. (Only received one
parameter with a pointer to the Interface object.)
The new ServiceFramework aims to solve these problems by working with
member functions and passing a generic context struct as parameter. This
struct can be extended in the future without having to update all
existing service implementations.
|
|
This has a huge fallout in terms of needing to fix other files because
all service implementations included that file.
|
|
Also enhances the GetServiceHandle implementation to be more accurate.
|
|
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.

the HLE handler superclass.

Further implementation will happen in a future commit.
Fixes a regression.

number of sessions that can be connected to an HLE service at the same time.

TranslateRequest and HandleSyncRequestImpl.
HandleSyncRequest now takes care of calling the command buffer translate function before actually invoking the command handler for HLE services.
|
|
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.

|
if it exists.
Pass the triggering ServerSession to the HLE command handler to differentiate which session caused the request.
|
|
and is now its own standalone class.
Interface is now used by aggregation in ClientPort, to forward service commands to their HLE implementation if needed.

of Inter Process Communication.
|
|
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.

This makes clang-format useful on those.
Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.

This reduces the time for a full recompile from 65.43s to 59.53s (~9%)

This coincidentally fixes an issue about the PTM service failing to create its SharedExtSaveData archive due to the FS service not being initialized by the time the creating code runs.
Ideally I'd like to move each process to its own folder, and have a single file per process that registers the service classes, which would be in their own files inside that folder. Then each service class would just call functions from the process to complete the commands.

Uses less memory (strings and function table is stored in constant data)
and speeds up start up (no need to allocate and copy strings).
