21590b0709 Miscellaneous DSi NAND fixes (#1852)
* Replace some standard I/O calls with Platform equivalents

- I missed a spot when I submitted that PR a few months ago

* Include <memory> in DSi_NAND.h

- Because it uses unique_ptr

* Split DSi_NAND::ReadHardwareInfo into ReadSerialData and ReadHardwareInfoN

* Add a RegionMask enum

* Move DSi NAND patching to the frontend

* Add DSiSupportedLanguageMask

- Not currently used by the frontend, but I use it in melonDS DS

* Remove some Platform::ConfigEntry values

- The core no longer needs to know about them
- The corresponding Config values are unchanged

* Mark NANDMount's destructor as noexcept

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

d4e51f8060 Refactor DSi_NAND (#1844)
* Refactor diskio's contents

- Change ff_disk_read_cb/write_cb into a std::function instead of a raw pointer
- Add const specifiers as needed

* Refactor DSi_NAND to manage the file system's mounted lifetime with RAII

* Split NANDMount into NANDMount and NANDImage

- NANDImage is used for information about the NAND that doesn't require decryption or filesystem access
- NANDMount is used to actually access the file system
- Both classes manage their respective resources (the NAND file handle and the NAND's mount) with RAII
- Also split the file loading into another function that I will remove in a later PR

* Make NANDMount immovable

* Remove NAND-loading code that I had sectioned off into a function

- Incomplete copypasta
- I must have gotten distracted

* Tidy up NANDImage's initialization

- Don't unmount the disk image if the constructor fails (that's NANDMount's job now)
- Only assign CurFile if the constructor succeeds

* Add some const-correctness

* Move DSi NAND initialization to the frontend

- The NANDImage is now installed via a unique_ptr in DSi

* Remove Platform::DSi_NANDPath

- Not Config::DSiNANDPath; that can still be configured as usual
- The core no longer needs to care

* Remove some stray parens

* Fix some firmware-related bugs I introduced

- Firmware settings are now properly saved to disk (beforehand I misunderstood when the firmware blob was written)
- Firmware is no longer overwritten by contents of wfcsettings.bin

* Slight cleanup

ee55677086 Assorted portability enhancements (#1800)
* Introduce some Platform calls for managing dynamic libraries

* Add Platform::WriteFATSectors

* Introduce some Platform calls for managing dynamic libraries

* Add Platform::WriteFATSectors

* Change includes of "../types.h" to "types.h"

- Makes it easier to directly include these headers in downstream projects

* Change an include of "../Wifi.h" to "Wifi.h"

* Allow CommonFuncs.cpp to compile on Android

* Tidy up some logging calls

- Use Platform::Log in LAN_Socket.cpp
- Soften some warnings to Debug logs (since they don't necessarily represent problems)

* Add Platform::EnterGBAMode

- Gracefully stop the emulator if trying to enter GBA mode

* Soften some logs that most players won't care about

* Soften some more logs

* Introduce Platform wrappers for file operations

* Fix pointer spacing

* Fix more style nits

* Log the errno when ftruncate fails

* Fix FileSeek offset argument

- With an s32 offset, we couldn't access files larger than 2GB

* Revise Platform::StopEmu to address feedback

- Remove Platform::EnterGBAMode in favor of adding a reason to Platform::StopEmu
- Also rename Platform::StopEmu to Platform::SignalStop
- Add an optional argument to NDS::Stop
- Use the new argument everywhere that the console stops itself

* Rename FileGetString to FileReadLine

- It conveys the meaning better

* Rename FileSeekOrigin::Set to Start

- It conveys the meaning better

* Change definition of FileGetString to FileReadLine

- Oops, almost forgot it

* Rename FlushFile to FileFlush

- To remain consistent with the other File functions

* Add a FileType usage

* Fix line break in FileSeekOrigin

- The enum is converted to fopen flags under the hood
- The file type is used to decide whether to add the "b" flag
- Some helper functions are exposed for the benefit of consistent behavior among frontends
- Equivalent behavior is maintained

* Fix a tab that should be spaces

* Use Windows' 64-bit implementations of fseek/ftell

* Move Platform::IsBinaryFile to Platform.cpp

- It could vary by frontend

* Remove an unused FileType

* Rename an enum constant

* Use Platform::DynamicLibrary to load libandroid

- And clean it up at the end

* Fix a typo

* Pass the correct filetype to FATStorage

- Since it can be used for DSI NAND images or for SD cards

* Remove Platform::FileType

2022-10-02 16:47:57 +02:00
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
