Subv 38a90882a4 Kernel/Synch: Do not attempt a reschedule on every syscall.
Not all syscalls should cause reschedules, this commit attempts to remedy that, however, it still does not cover all cases.

Subv 5b1edc6ae7 Fixed the codestyle to match our clang-format rules. 2016-12-14 12:35:01 -05:00
Subv 406907d570 Properly remove a thread from its wait_objects' waitlist when it is awoken by a timeout. 2016-12-10 13:29:31 -05:00
Subv ebbb55ec8f Moved the HLE command buffer translation task to ServerSession instead of the HLE handler superclass. 2016-12-09 12:52:12 -05:00
Subv 17b29d8865 WaitSynch: Removed unused variables and reduced SharedPtr copies.
Define a variable with the value of the sync timeout error code.

Use a boost::flat_map instead of an unordered_map to hold the equivalence of objects and wait indices in a WaitSynchN call.
2016-12-09 12:23:09 -05:00
Subv 386112da32 Added a framework for partially handling Session disconnections.
Further implementation will happen in a future commit.

Fixes a regression.

Subv c93c5a72bb Return an error code when connecting to a saturated port.
The error code was taken from the 3DS kernel.
2016-12-05 13:59:57 -05:00
Subv 00f0c77570 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.
2016-12-05 12:05:00 -05:00
Subv 29d809b6e1 Kernel: Remove the Redirection handle type. 2016-12-05 11:13:22 -05:00
Subv dd8887c8cf KServerPorts now have an HLE handler "template", which is inherited by all ServerSessions created from it. 2016-12-05 11:02:08 -05:00
Subv bdad00c73f Threading: Added some utility functions and const correctness. 2016-12-04 09:58:36 -05:00
Subv 8634b8cb83 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.

Subv 2ce61344d6 Declare empty ServerSession and ClientSession constructors as default. 2016-12-02 22:58:02 -05:00
Subv 2eceee3a4c Fixed the rebase mistakes. 2016-11-30 23:28:31 -05:00
Subv 009b15b3aa 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.
2016-11-30 23:12:35 -05:00
Subv c5e7e0fa26 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 c19afd2118 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.
2016-11-30 23:03:59 -05:00
Subv 0a33d915f8 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 073653e858 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.

Subv 1323ab2f5f Kernel/Loader: Grab the system mode from the NCCH ExHeader.

Subv 1bd0cf542f Kernel/SharedMemory: Properly implemented shared memory support.

Shared memory areas are now properly mapped into the target processes when calling svcMapMemoryBlock.

Removed the APT Shared Font hack as it is no longer needed.

Subv 5b7f86708c Kernel/Threading: Warn when a thread can be scheduled in the Syscore (Core 1).
We do not currently implement any cores other than the AppCore (Core 0).
2016-05-07 10:23:03 -05:00
Subv d192fb066d Kernel/Threads: Dynamically allocate the TLS region for threads in the BASE region of the linear heap.
Each thread gets a 0x200-byte area from the 0x1000-sized page, when all 8 thread slots in a single page are used up, the kernel allocates a new page to hold another 8 entries.

This is consistent with what the real kernel does.
