faf3c0f2e0 Add Gaussian (SNES) audio interpolation
Probably not a good choice for most DS games unless you really want a
very soft sound, but it could be fun if you wanted to run lolSnes in
melonDS :p

a4b2b0c40d Resolve or silence some warnings (#1905)
* Resolve some warnings

- Their frequent appearance in the build logs is driving me nuts

* Silence warnings about `offsetof`

* Don't apply `-Wno-invalid-offset` to C, only to C++

9bfc9c08ff Sprinkle const around where appropriate (#1909)
* Sprinkle `const` around where appropriate

- This will make it easier to use `NDS` objects in `const` contexts (e.g. `const` parameters or methods)

* Remove the `const` qualifier on `DSi_DSP::DSPRead16`

- MMIO reads can be non-pure, so this may not be `const` in the future

090627b3c1 Remove the last ConfigEntry state (#1902)
* Get rid of `ConfigEntry::ExternalBIOSEnable`

- Now the BIOS files themselves are checked
- The frontend's `Config::ExternalBIOSEnable` is not affected

* Add `JITArgs`

* Pass the JIT status to the `ARM` constructors

* Encapsulate `NDS::EnableJIT`

* Pass `JITArgs` to `ARMJIT`'s constructor

* Remove the `JIT_*` `ConfigEntry`s in favor of members

- Allow all the JIT args to be set with `NDS::SetJITArgs`
- Encapsulate the JIT-related parameters in `ARMJIT` so they can reset the block cache if changed
- Update the active (or newly-created) console in the frontend with adjusted JIT args

* Make audio bit depth and interpolation configurable in `NDSArgs`

- Define enums for both
- Give those settings default values in `NDSArgs`
- Remove `ConfigEntry::AudioBitDepth`
- Initialize these settings in the relevant SPU constructors

* Move the last DSi-specific logic in `Reset` to its own subclass

* Remove `ConfigEntry::DSi_FullBIOSBoot`

- Add members to `DSi` instead for getting and setting this
- Update the frontend to accommodate these changes

* Oops, missed a spot

* Remove `ConfigEntry::Firm_MAC` and `Platform::GetConfigArray`

- Also move the MAC parsing code to `ROMManager`

* Remove the last `ConfigEntry` state

- Make GDB support configurable via members

* Add some `#ifdef`s that I'd almost forgotten

ae91d89f7c Use a constexpr-friendly cosine implementation (#1903) 2023-12-05 12:41:28 +01:00
da8d413ad9 Slight cleanup to SPU (#1900)
* Move `SPUChannel` and `SPUCaptureUnit` to be stored inside `array`s instead of allocated separately

* Default-initialize most of `SPU`'s fields

* Generate the interpolation tables at compile-time with `constexpr`

- Now it's faster and thread-safe

* Slight cleanup in SPU

- Iniitialize most fields in the class declaration

* Mark `SPU` as `explicit`

e973236203 Refactor NDS and DSi to be objects (#1893)
* First crack at refactoring NDS and DSi into objects

- Remove all global/`static` variables in `NDS` and related classes
- Rely more on virtual dispatch when we need to pick methods at runtime
- Pass `NDS&` or `DSi&` to its constituent components where necessary
- Introduce some headers or move some definitions to break `#include` cycles

* Refactor the frontend to accommodate the core's changes

* Move up `SchedList`'s declaration

- Move it to before the components are initialized so the `map`s inside are initialized
- Fields in C++ are initialized in the order they're declared

* Fix a crash when allocating memory

* Fix JIT-free builds

* Fix GDB-free builds

* Fix Linux builds

- Explicitly qualify some member types in NDS, since they share the same name as their classes

* Remove an unnecessary template argument

- This was causing the build to fail on macOS

* Fix ARM and Android builds

* Rename `Constants.h` to `MemConstants.h`

* Add `NDS::IsRunning()`

* Use an `#include` guard instead of `#pragma once`
2023-11-28 23:16:41 +01:00
346dd4006e Move all core types into namespaces (#1886)
* Reorganize namespaces

- Most types are now moved into the `melonDS` namespace
- Only good chance to do this for a while, since a big refactor is next

* Fix the build

* implement DSi RTC commands

* set up RTC clock timer. lay down basic idea of a clock.

* make the date/time registers writable

* move RTC state to its own structure, to make it easier to deal with

* more RTC work
lay base for date/time dialog

3ab752b8ca GDB stub (#1583)
* gdbstub beginnings

* gdbstub: finish gdb impl things, next up is integration with melonDS

* holy fuck the gdbstub works

* gdb breakpoints work, but there's a mysterious crash on continue

* fix memory corruption that sometimes happened, and make resetting the console thru gdb work

* remove some gdb debug printing

* fix things in gdbstub

* separate option for enabling gdbstub

* add mode-dependent CPU registers

* C++ize the GDBstub code

* add gdbstub config in emu settings dialog

* make sure gdb is disabled when jit is enabled

* Remove unnecessary compiler flags, mark ARMJIT assembly code as no-execute-stack

This hardens the binary a little bit against common exploitation methods

* add option to wait for debugger attach on startup

* only insert GNU stack notes on linux

* disable gdbstub enable checkbox when jit is enabled

* fix non-linux incompatibilities

* enable gdbstub by default

* fix issues with gdbstub settings disable stuff

* format stuff

* update gdb test code

* Fix segfault when calling StubCallbacks->GetCPU()

C++ overrides are hard. Please I'm just a lowly C programmer.

* fix packet size not being sent correctly

Thanks to @GlowingUmbreon on Github for troubleshooting this

* fix select(2) calls (i should read docs more properly)

* fix GDB command sequencing/parsing issue (hopefully)

* [GDB] implement no-ack mode

* fix sending ack on handshake

* get lldb to work

db963aa002 Make the NDS teardown more robust (#1798)
* Make cleanup a little more robust to mitigate undefined behavior

- Add some null checks before cleaning up the GPU3D renderer
- Make sure that all deleted objects are null
- Move cleanup logic out of an assert call
- Note that deleting a null pointer is a no-op, so there's no need to check for null beforehand
- Use RAII for GLCompositor instead of Init/DeInit methods

* Replace a DeInit call that I missed

* Make ARMJIT_Memory less likely to generate errors

- Set FastMem7/9Start to nullptr at the end
- Only close and unmap the file if it's initialized

* Make Renderer3D manage its resources with RAII

* Don't try to deallocate frontend resources that aren't loaded

* Make ARMJIT_Memory::DeInit more robust on the Switch

* Reset MemoryFile on Windows to INVALID_HANDLE_VALUE, not nullptr

- There is a difference

* Don't explicitly store a Valid state in GLCompositor or the 3D renderers

- Instead, create them with static methods while making the actual constructors private

* Make initialization of OpenGL resources fail if OpenGL isn't loaded

* assert that OpenGL is loaded instead of returning failure

79dfb8dc8f Introduce Platform::Log (#1640)
* Add Platform::Log and Platform::LogLevel

* Replace most printf calls with Platform::Log calls

* Move a brace down

* Move some log entries to one Log call

- Some implementations of Log may assume a full line

* Log the MAC address as LogLevel::Info

b1e4bd5520 merge local_wifi (#1516)
* attempt at betterer wifi

* add preliminary sync mechanism
* fix gaps in wifi implementation

* move local-MP comm to its own module instead of cramping Platform.cpp

* remove some stupid cruft

* as you wish, Sorer

(starting work on shared-memory system)

* shared-memory IPC that actually works (albeit Windows-only for now)

* shut up logging from NULL writes on ARM7 (ffs Nintendo learn to code)

* get this somewhat good

* leave client sync mode when host deauths. makes download play actually work.

* start implementing MP-comm error handling

* * add MP-reply error counters
* feeble attempt at fixing slowdown/desync/etc problems

* somewhat better exchange/sync method

* * when entering power-saving mode, be sure to finish transferring the current frame first
* fix misc bug due to old cruft leftover

makes for a more stable connection

* remove a bunch of cruft

* set wifi time interval to 34 cycles instead of 33. games seem sensitive to the general timing of wifi vs the rest of the system, and this seems to make things run better, atleast until I rewrite this to use a proper scheduler.

* more graceful handling of disconnects

* deal with FIFO overflow more gracefully

* BAHAHAHAHAHAHAHAHHHH

THE SNEAKY BASTARDS

so, when the DS receives a beacon with the right BSSID

that beacon's timestamp is copied to USCOUNTER

* attempt at making the connection process smoother for weird games

* * begin adding POWCNT2, only applies to wifi for now
* begin work on wifi scheduler

* implement the shitty timers

* add the RF wakeup thing

* begin work on receiving frames. for now it can just receive melonAP beacons, but hey, it's a start.

* add enough TX functionality that online wifi is a possibility again.

* there are problems with this scheduler thing. committing it anyway

* kind of a rollback... we're gonna work out a compromise on this, I guess

* don't transmit shit if RXCNT.bit15 isn't set

* move RX-finish to its own function. more accurate filtering. implement RXFILTER.

* remove some cruft

* fix some of the shittiness when trying to connect more than two players

* fix some more shittiness

* fix more wifi shittiness (mainly don't try to receive shit while sending a frame)

* run wifi every 8µs. improves performance.

* fix IRQ14/IRQ15

* make this work under Linux

* Make it work on macOS, for now using a custom sem_timedwait
implementation.

If anyone knows anything about mach ports and have an idea for how to
make this work using mach IPC, please do let me know.

* 25ms seems like a good timeout

* begin work on proper multiplayer UI shito.

for now, determine a global instance ID, and derivate the system MAC from it. remove 'randomize MAC' option.

* finish removing RandomizeMAC

* lay groundwork for instance-unique config

* work some on the UI... make it not labelled Fart

* more UI work: make it explicit that some things are instance-unique

* separate firmware files for multiplayer instances

* make instances save to different save files, too

* more UI work, make things somewhat less shitty

* lay base for the multiplayer settings dialog

* actually hook up most of that dialog

* actually implement the fun audio settings

* ensure all the wifi shit is properly savestated and reset. properly update timings for the wifi region when wifi is disabled.

* add more fun labels

* * ignore WEP frames if WEP is off
* implement RX_LEN_CROP

* fake enough of WEP processing to make Inazuma Eleven work

* * do not copy more ROM banner data than actually needed
* avoid trying to read out of bounds if the banner offset is bad

* Fix oversight with the preferences action causing the build to fail on macOS
