If a thread was woken up by something, cancel the wakeup timeout.

There is no documentation available on this function, but we set the result to false as a stub.
This allows Super Little Acorns to move all the way in game with pp3c.

ARM_Disasm only has static methods, so there's no need to have an instance of it.
|
|
|
|
|
|
This will keep track of idle ticks for us, and fixes some tickcount-related issues
|
|
It will now properly wait the specified number of nanoseconds and then wake up the thread.
|
|
These need to be done as a 64-bit operation.
|
|
This thread will not actually execute instructions, it will only advance the timing/events and try to yield immediately to the next ready thread, if there aren't any ready threads then it will be rescheduled and start its job again.
|

|
|
Wasn't doing proper sign-extension
|
|
Replace all the C-style complicated buffer management with a std::deque.
In addition to making the code easier to understand it also adds support
for non-POD IdTypes.
Also clean the rest of the code to follow our code style.
|
|
Implemented the required calls to make it work.
CoreTiming: Added a new logging class Core_Timing.

Just in case some game studio let the intern write inline assembly or something.

- Hack to work around games checking that the DSP event has been signaled by a real DSP interrupt.
|
|
|
|
|
|
This will happen when the mutex is already owned by another thread. Should fix some issues with games being stuck due to waiting threads not being awoken.
|
|
citra already has its own typedefs like this.
|
|
|
|
Each archive now takes a mount point of either NAND or SDMC, and builds its own directory structure there, trying to simulate an HLE-friendly hardware layout
|
|
under /nand/title/high/low/content/00000000.app.romfs
|

(Thanks 3dmoo!)
|
|
|
|
|
|
Also joins the REV ops into one common place.
|
|
|
|
|
|
This is to better represent the hardware layout, they are still aren't quite accurate, but this better and will help a bit when implementing the other archives like NAND-RO and NAND-RW
|
|

|

Fixed a few warnings and cleaned up the code
|
|
This allows Steel Diver to boot further, some files are needed.
This is still not ready and needs a big cleanup, this will possibly be delayed until the way we handle archives is fixed (with factory classes instead of ahead-of-time creation of archives)
|

Technically eliminates two memory leaks as well.

Stubbed CreateMemoryBlock
Using Berkeley sockets, and Winsock2.2 on Windows.
So far ftpony creates the socket and accepts incoming connections
SOC_U: Renamed functions to maintain consistency
Also prevents possible scope errors / conflicts with the actual Berkeley socket functions
SOCU: Close all the opened sockets when cleaning up SOCU

It's not really known how this actually works. Some testing has shown that this probably performs no filtering, and common usage in games suggests it's not actually resizing the image at all.
However, this patch does seem to fix some homebrew showing quasi-duplicated images while still keeping other applications in a working state.

They will be stored in /extsavedata/SDMC and /extsavedata/NAND respectively.
Also redirect some APT_A functions to their APT_U equivalents.
Implemented the gamecoin.dat file in SharedExtSaveData in the PTM module.
Implemented formatting the savegame.
Retake a previous savegame if it exists instead of reporting them as not formatted every time a game is loaded.
|

This handle manager more closely mirrors the behaviour of the CTR-OS
one. In addition object ref-counts and support for DuplicateHandle have
been added.
Note that support for DuplicateHandle is still experimental, since parts
of the kernel still use Handles internally, which will likely cause
troubles if two different handles to the same object are used to e.g.
wait on a synchronization primitive.

That's the language id block, we're using LANGUAGE_EN for now. This block allows some games to boot further
|
|
It is now kept in memory as per 3dbrew, all updates happen on memory, then they can be saved using UpdateConfigNANDSavegame.
|
|
Seems to allow some games to boot further, thanks @Normmatt for sharing this information
|
|
Added a "config" file to the CFG process service (CFG:U), and added a few default blocks to it.
Implemented GetSystemModel and GetModelNintendo2DS
|
|
|
|
Tested with hwtests.
|
|
|
|
- Removed unused VBLANK sleep mode
- Added error log for bad context switch
- Renamed VerifyWait to CheckWaitType to be more clear
|
|
|
|
|
|
|
|
|
|
This boots a few (mostly Nintendo 1st party) games further.

The lower-bound would never be negative like it should
|
|
|
|
|
|
|
|
Maybe sometime when we actually implement that
|
|
|
|
We still don't know what the other parameters do, but they appear to be very similar to those of FormatThisUserSaveData.
Most likely FormatThisUserSaveData is just an alias for FormatSaveData with LowPathType Empty

It will be stored in the /syssavedata folder. This archive is user by various Services and possibly games via the FS:U service.
|
|
|
|
The savedata for each game is stored in /savedata/<ProgramID> for NCCH files. ELF files and 3DSX files use the folder 0 because they have no ID information
Got rid of the code duplication in File and Directory
Files that deal with the host machine's file system now live in DiskFile, similarly for directories and DiskDirectory and archives with DiskArchive.
FS_U: Use the correct error code when a file wasn't found
|
|
Reference manual states these must be set to zero if this case is true.
|
|
Broken from the same reason SADD16 was.
The lo part of the result should only be constructed from the lo halfwords of rm and rn.
The hi part of the result should only be constructed from the hi halfwords of rm and rn.
|
|
|
|
There's no reason to have these in the outer-most scope.
|
|
The lo and hi parts of the result were being constructed as a result of hi and lo halfword intermixing from the rm and rn regs. However the lo part of the result should be constructed only from the lo halfwords of rm and rn, and the hi part of the result should only be constructed from the hi halfwords of rm and rn.

Wrong values were being multiplied together.
|
|
|

The only difference between these ops is one adds and one subtracts. Everything is literally the same.
|

|
- Refactor FS::Archive internals to make Archive creation and lifetime
management clearer.
- Remove the "Archive as a File" hack.

I couldn't find any information about this service...
|
|
|
|
Apparently nothing at all is known about this service...
|
|
This is a first step at fixing the conceptual insanity that is our
handling of service and IPC calls. For now, interfaces still directly
derived from Session because we don't have the infrastructure to do it
properly. (That is, Processes and scheduling them.)
|
|
Rotation bits are 10 and 11, not 9 and 10.
|
|
|
|
|
|
Got rid of I/O address's since the I/O addresses range's overlap with other
address's types such as vram, these I/O addresses need to be done in an different
way.

This behavior was tested on hardware, however i'm still not sure what use the "initial_count" parameter has
|
|
ToDo: Implement svcReleaseSemaphore
* Some testing against hardware needed
|

- Linear simply indicates that the mapped physical address is always MappedVAddr+0x0C000000, thus this memory can be used for hardware devices' DMA (such as the GPU).

The 3DS allows the user to read from files opened with the Write access modifier, even if he did not specify the Read access modifier.
Open the files in binary mode so that we can prevent CR/LF problems in Windows, where a line-end is replaced by these two bytes instead of just 0xA, this was causing problems with the GetSize test
|
|
|
|
|
|
|
|
|
|
This is in line with what the hardware itself does.
It does this by splitting the initial directory opening into Directory.Open(), which will return false if a stat fails.
Then, Archive::OpenDirectory will return nullptr, and archive.cpp will return an error code .
|
|
Moved Mutex::WaitSynchronization to the end of the file.
|
|
|
|
Also resume only the next immediate thread waiting for the mutex when it is released, instead of resuming them all.
|
|
Use the next_thread_id variable directly.
|
|
|
|
|
|
For now threads are using their Handle value as their Id, it should not really cause any problems because Handle values are unique in Citra, but it should be changed. I left a ToDo there because this is not correct behavior as per hardware.
|

Should theoretically push retail stuff further along

Seems (probably just placebo/wishful thinking) to make it slightly
faster. Also reduces memory usage and makes shutdown when debugging from
MSVC fast.

All service calls in the CTR OS return result codes indicating the
success or failure of the call. Previous to this commit, Citra's HLE
emulation of services and the kernel universally either ignored errors
or returned dummy -1 error codes.
This commit makes an initial effort to provide an infrastructure for
error reporting and propagation which can be use going forward to make
HLE calls accurately return errors as the original system. A few parts
of the code have been updated to use the new system where applicable.
One part of this effort is the definition of the `ResultCode` type,
which provides facilities for constructing and parsing error codes in
the structured format used by the CTR.
The `ResultVal` type builds on `ResultCode` by providing a container for
values returned by function that can report errors. It enforces that
correct error checking will be done on function returns by preventing
the use of the return value if the function returned an error code.
Currently this change is mostly internal since errors are still
suppressed on the ARM<->HLE border, as a temporary compatibility hack.
As functionality is implemented and tested this hack can be eventually
removed.

Most functions already operate on std::strings. This also removes the need to manually null terminate thread names.

entry_point would not be added to the string. Also used StringFromFormat

HID: Fix typo with DisableGyroscopeLow command.

This cleans up the mess that address reading/writing had become and makes the code a *lot* more sensible.
This adds a physical<->virtual address converter to mem_map.h. For further accuracy, we will want to properly extend this to support a wider range of address regions. For now, this makes simply homebrew applications work in a good manner though.
|
|
|
|
While it was some nice and fancy template usage, it ultimately had many practical issues regarding length of involved expressions under regular usage as well as common code completion tools not being able to handle the structures.
Instead, we now use a more conventional approach which is a lot more clean to use.
