Subv a7a5c5aa0d Kernel/IPC: Partially implement MappedBuffer translation. 
Right now only MappedBuffers that only span a single page and are not aligned are implemented.

MappedBuffers are unmapped during the reply part of ReplyAndReceive. Only unmapping of ReadOnly buffers is currently implemented.
 2018-01-23 08:27:00 -05:00
Subv 928202f744 Kernel/VMManager: Added a function to map a block of memory into the first available address after a given base. 2018-01-23 08:24:15 -05:00
Subv 07089cfb3c Tests: Added some tests for the VMManager class. 
Covering basic operations like mapping, unmapping, reprotecting and changing memory state.
 2018-01-23 08:21:12 -05:00
Subv e4f35f70ac Memory: Added a function to change the memory state of an address range. 
This will be useful when implementing memory aliasing operations.
 2018-01-23 08:19:47 -05:00
Subv 34685f48dc GSP: Allow the signaling of the PDC0/1 interrupts even if the GPU right hasn't been acquired. 
This was verified with a hwtest.
 2018-01-06 13:51:33 -05:00
Subv aa90198ec5 Services: Make SessionDataBase's destructor virtual. 2018-01-03 10:52:46 -05:00
Subv 75f68c4860 Services/GSP: Mark the thread ids as unused when a GSP session is destroyed. 
This fixes the games that call RegisterInterruptRelayQueue and UnregisterInterruptRelayQueue frequently.
 2018-01-02 12:10:58 -05:00
Subv d17f148e48 Services/GSP: Assign a thread id to each connected session when the session is created. 
Most applications call AcquireRight before calling RegisterInterruptRelayQueue so we can't assign the thread id there.
This fixes the bug with LLE applets not launching properly.
 2018-01-02 12:07:26 -05:00
Subv fbef978b98 GSP: Return the correct result code if AcquireRight is called multiple times from the same thread. 2017-12-24 12:15:01 -05:00
Subv 68fc3b36e6 HLE/GSP: Only trigger GSP interrupts for the current active GSP thread. 
This is true for all interrupts except PDC0 and PDC1, which should be triggered for all registered threads.

TODO: The real GSP module seems to only trigger PDC0 after updating the screens (both top and bottom). PDC1 doesn't seem to be triggered at all.
 2017-12-24 12:15:00 -05:00
Subv 05a44ed353 HLE/GSP: Keep track of the thread that currently has the GPU right. 
This thread is the only one for which the GSP interrupts should be signaled, except for the PDC0/1 interrupts.
 2017-12-24 12:14:59 -05:00
Subv aabb07cca4 HLE/GSP: Make RegisterInterruptRelayQueue work in a per-session basis. 
The registered interrupt event is unique to each session that calls RegisterInterruptRelayQueue, and only that event should be reset when UnregisterInterruptRelayQueue is called.

Subv 3652809408 HLE: Convert GSP_GPU to ServiceFramework. 
The only functional change is the error handling of GSP_GPU::ReadHWRegs function. We previously didn't return error codes (not even for success). The new returns were found by reverse engineering the GSP module.

Subv f4b595331f GSP/GPU: Make FrameBufferInfo::active_fb use the entire u32 instead of just one bit. 
The GSP module reads the entire 32 bit word from this field to determine the framebuffer.

Terminating processes with ready threads is not currently implemented and will assert. It is currently unknown how the 3DS kernel stops ready threads or threads running in another core.

Subv daecd812b0 HLE/Services: Allow specifying a SessionData template parameter to ServiceFramework. 
Some services can have multiple clients at the same time, and they identify the different clients using the server session as a key.
This parameter (if present) should be a structure that contains the per-session data for each service.
The data can be retrieved using ServiceFramework::GetSessionData(session)

Subv c9ddd5b0ae HLE/FS: Implemented FSFile::OpenSubFile. 
The File class now holds a list of connected sessions along with data unique to each session.

A subfile is a window into an existing file. They have a few limitations compared to normal files:

* They can't be written to.
* They can't be flushed.
* Their size can not be changed.
* New subfiles can't be created from another subfile.

We don't yet implement the SEEDDB store.
This number is supposed to be modified by the AddSeed function (0x087A0180) but there's too little info about it on 3dbrew.

Subv 8e9b55e939 NCCH: Load the "logo" file from the specified offset if it's present instead of the ExeFS. 
This is "new" behavior as of firmware 5.0.0-11, older titles have the logo offset and size set to 0, indicating that the logo is stored in the ExeFS.

Subv 37cb18358b HLE/FS: Always use 0x48000 as the high dword when opening the SharedExtData archive 
The FS module overrides whatever value was in the saveid high dword with 0x48000 when trying to open the archive.

This fixes the problem where the Home Menu would create a few SharedExtData archives with 0x48000 as the saveid high, but then try to open them with 0 as the high value and fail.

Subv e90daa6a4f Kernel/IPC: Add a small delay after each SyncRequest to prevent thread starvation. 
In a real 3DS, threads that call svcSyncRequest are put to sleep until the server responds via svcReplyAndReceive. Our HLE services don't implement this mechanism and are effectively immediate from the 3DS's point of view. This commit makes it so that we at least simulate the IPC delay.

Specific HLE handlers might need to put their callers to sleep for a longer period of time to simulate IO timings. This is their responsibility but doing so is currently not implemented.

See https://gist.github.com/ds84182/4a7690c5376e045cab9129ca4185bbeb for a test that was not passing before this commit.

Subv afb6dd7747 HLE/SRV: Don't return the port handle if it isn't available when calling GetServiceHandle. 
This was incorrect behavior that somehow found its way to 3dbrew. The correct behavior is to sleep until the port becomes available again and then return a session to it.

This is currently unimplemented due to the inability to put a guest thread to sleep during HLE requests.

The correct behavior was reverse engineered by TuxSH a while ago but we never corrected the code in citra.

Subv 35a61ab053 HLE/Tests: Added tests for the StaticBuffer IPC HLE translation. 2017-11-12 11:00:00 -05:00
Subv c9c1ba0952 Kernel/IPC: Implement StaticBuffer translation for HLE services that use the HLERequestContext architecture. 
The real kernel requires services to set up their static buffer targets ahead of time. This implementation does not require that and will simply create the storage for the buffers as they are processed in the incoming IPC request.

Static buffers are kept in an unordered_map keyed by their buffer id, and are written into the already-setup area of the request thread when responding an IPC request.

This fixes a regression (crash) introduced in #2992.

This PR introduces more warnings due to the [[deprecated]] attribute being added to void PushStaticBuffer(VAddr buffer_vaddr, size_t size, u8 buffer_id); and VAddr PopStaticBuffer(size_t* data_size);

This lets LLE services be properly notified of clients closing the connection so they can end their handler threads instead of letting them linger indefinitely, taking up connection slots in their parent port.
