bf232b89f3 Improved the algorithm for GetHighestPriorityReadyThread. 2016-12-06 19:15:32 -05:00
Subv
06b2b80d31 Return an error code when connecting to a saturated port. 
The error code was taken from the 3DS kernel.

708ece3fff Split SessionRequestHandler::HandleSyncRequest into HandleSyncRequest, TranslateRequest and HandleSyncRequestImpl. 
HandleSyncRequest now takes care of calling the command buffer translate function before actually invoking the command handler for HLE services.

728bb5f40b Kernel: Remove the Redirection handle type. 2016-12-05 11:13:22 -05:00
Subv
977039e722 KServerPorts now have an HLE handler "template", which is inherited by all ServerSessions created from it. 2016-12-05 11:02:08 -05:00

44c59feca6 Threading: Added some utility functions and const correctness. 2016-12-04 09:58:36 -05:00
Subv
5bc10a74f6 Threading: Reworked the way our scheduler works. 
Threads will now be awakened when the objects they're waiting on are signaled, instead of repeating the WaitSynchronization call every now and then.

The scheduler is now called once after every SVC call, and once after a thread is awakened from sleep by its timeout callback.

This new implementation is based off reverse-engineering of the real kernel.

See https://gist.github.com/Subv/02f29bd9f1e5deb7aceea1e8f019c8f4 for a more detailed description of how the real kernel handles rescheduling.

4703561c9e Declare empty ServerSession and ClientSession constructors as default. 2016-12-02 22:58:02 -05:00
Subv
4c4f50dfaf Fixed the rebase mistakes. 2016-11-30 23:28:31 -05:00
Subv
4f2326c8a9 A bit of a redesign. 
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.

d2305d375f IPC/HLE: Associate the ClientSessions with their parent port's HLE interface if it exists. 
Pass the triggering ServerSession to the HLE command handler to differentiate which session caused the request.
 2016-11-30 23:04:00 -05:00
Subv
edcacd7cdd Kernel/HLE: Service::Interface no longer inherits from any Kernel object, 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.

96df92e98f fixup! Kernel/IPC: Use Ports and Sessions as the fundamental building block of Inter Process Communication. 2016-11-30 23:02:06 -05:00
Subv
302ef594a6 Kernel/IPC: Use Ports and Sessions as the fundamental building block of 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.

d00d0d61e0 Kernel/Loader: Grab the system mode from the NCCH ExHeader. 
3dsx and elf files default to system mode 2 (96MB allocated to the application).

This allows Home Menu to boot without modifications.

1138ec0d49 Remove empty newlines in #include blocks. 
This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.
