ControllerEmu::Control instances have a unique_ptr<ControlReference>
member, which is passed either an InputReference or OutputReference.
Without this virtual destructor, deleting a derived class through a
pointer to the base class is undefined behavior.
This prevents Dolphin from writing to /sys/uid.sys (on the host; root
partition) when installing a WAD before starting emulation, because
the session root is not initialized at that moment.
Incidentally, this also gets rid of a singleton.
instruction tables
Previously, all of the internals that handled how the instruction tables
are initialized were exposed externally. However, this can all be made
private to each CPU backend.
If each backend has an Init() function, then this is where the instruction
tables should be initialized, it shouldn't be the responsibility of
external code to ensure internal validity.
This allows for getting rid of all the table initialization shenanigans
within JitInterface and PPCTables.
ControllerEmu, the class, is essentially acting like a namespace for
ControlGroup. This makes it impossible to forward declare any of the
internals. It also globs a bunch of classes together which is kind of a
pain to manage.
This splits ControlGroup and the classes it contains into their own source
files and situates them all within a namespace, which gets them out of
global scope.
Since this allows forward declarations for the once-internal classes, it
now requires significantly less files to be rebuilt if anything is changed
in the ControllerEmu portion of code.
It does not split out the settings classes yet, however, as it
would be preferable to make a settings base class that all settings derive
from, but this would be a functional change -- this commit only intends to
move around existing code. Extracting the settings class will be done in
another commit.
Several of the things done while performing a scan are logically their own
behavior (e.g. loading a titles file, checking if an entry should be added, etc).
The three parameter AnalogStick constructor takes an internal name, a
display name, and a default radius argument. The delegated constructor is
the one that calls the ControlGroup constructor, setting the group type,
so passing the group type here is a logic bug.
The only reason this appeared to work despite this bug is because
GROUP_TYPE_STICK has a value of 1, and the default radius value used for
attachment sticks is 1.0.
This implements MIOS's PPC bootstrapping functionality, which enables
users to start a GameCube game from the Wii System Menu.
Because we aren't doing Starlet LLE (and don't have a boot1), we can
just jump to MIOS when the emulated software does an ES_LAUNCH or uses
ioctlv 0x25 to launch BC.
Note that the process is more complex on a real Wii and goes through
several more steps before getting to MIOS:
* The System Menu detects a GameCube disc and launches BC (1-100)
instead of the game. [Dolphin does this too.]
* BC, which is reportedly very similar to boot1, lowers the Hollywood
clock speed to the Flipper's and then launches boot2.
* boot2 sees the lowered clock speed and launches MIOS (1-101) instead
of the System Menu.
MIOS runs instead of IOS in GC mode and has an embedded GC IPL (which
is the code actually responsible for loading the disc game) and a PPC
bootstrap code. To get things working properly, we simply need to load
both to memory, then jump to the bootstrap code at 0x3400.
Obviously, because of the way this works, a real MIOS is required.
It held a raw pointer to a IOS::HLE::Device::BluetoothEmu that is not
guaranteed to exist (and of course, nothing checked that it wasn't
nullptr), but what is more, it's totally unnecessary because we have
IOS::HLE::GetDeviceByName().
Since we cannot always inform the host that Wii remotes are
disconnected from ES, that is now done in BluetoothEmu's destructor.
Unless IOS failed at ES_Launch, it doesn't appear to write anything
back to the request after a launch, because the request is never
actually replied to in the normal way.
So let's just drop the writes to make things less confusing.
This ioctlv is used to launch BC. Not sure if that's useful,
since only the system menu is known to launch BC and it does that
through a regular ES_LAUNCH; but let's implement it anyway.
(Implementation based on IOS59.)
Some minor changes to make things slightly less confusing:
* Reinit doesn't actually init anything. It just adds static devices to
the map, so let's give it an actually descriptive name. And let's not
expose it in the header when it should not be.
* Reset's parameter name was changed from "force" -- which totally does
not describe what it does -- to "clear_devices".
* Add a reload function which handles the reload process properly
(reset all devices, set up memory values, re-add devices) and
without publicly exposing implementation details.
Shouldn't make any difference in practice because
both IsRecordingInput and IsNetPlayRunning should
be false if a temporary NAND isn't being set up,
but doing it this way is cleaner regardless.
Splits DVD reads up into smaller chunks so that data is available
before the final interrupt is triggered. This better simulates the DMA
that happens on a real device, which some games will take advantage of -
by either playing back data as it is loading or by using data that is
going to be overwritten shortly by an outstanding read.
Better separation of concerns. Relegates `ControllerInterface` to
enumerating input controls, and the new `ControlReference` deals with
combining inputs and configuration expression parsing.
ControllerEmu is a massive class with a lot of nested public classes.
The only reason these are nested is because the outer class acts as a
namespace. There's no reason to keep these classes nested just for that.
Keeping these classes nested makes it impossible to forward declare them, which leads to quite a few includes in other headers, making compilation take
longer.
This moves the source files to their own directory so classes can be
separated as necessary to their own source files, and be namespaced under the
ControllerEmu namespace.
To use it, with a modern LLVM (3.9+), set your CMAKE_PREFIX_PATH
to point to the LLVM install folder or to a LLVM build folder.
We're linking ALL of LLVM libs since I don't really know which ones we need.
LTO will take care of sliming the binary size...
The second output vector should not be written to for
IOCTLV_NCD_READCONFIG. If it is, the system menu will never attempt
to open /dev/net/wd/command and request a Wi-Fi scan.
Symbols map may not only end with a \n, but they may also end with \r\n and only the \n would get removed. This is the case with the Super Mario Sunshine map file which resulted in a weird looking symbols list and thus made it harder to scroll through it. This removes the \r after the \n has been removed if it's present.
Using the AVCodecContext contained in AVStream for muxing is officially
discouraged[1] and AVStream::codec was deprecated in favor of
AVStream::codecpar in libavformat 57.33.100 / 57.5.0.

Any functions left exposed are used elsewhere through the main_window
global. May as well prevent any more functions from being used in that
manner where possible.
Utilizes the event system (which is what should have been done here
initially), in order to prevent coupling between two different window frames.
This also makes booting games more versatile using the UI event system,
as the event can just act as a carrier for the filename, making directly
calling boot functions unnecessary. All that's needed is for the event to
propagate to the frame.
Since files from Data/Sys are collected and added to a built macOS .app
bundle using GLOB, any new files won't get picked up until the next time
CMake is run. Tell CMake it should re-run itself every time the directory
is touched.
This prevents panic alerts from showing up three times when starting
Wii emulation whenever libusb could not be initialized. The user has
already seen a warning at startup -- no need to warn them 3 more times.
The built-in `configure_file` command correctly handles the case where
none of the variables change and scmrev.h doesn't need to be rebuilt.
This saves a full re-link of Dolphin any time CMake is re-run.
The usbdk backend is the only libusb backend that has official support
for isochronous transfers (which are required for Wii Speak,
microphones and cameras). And it's actively developed and maintained.
This reimplements the USB HID v4 IOS device using the new common
USB code (to reuse more code and allow emulated HIDs to be added
more easily in the future).
The main difference is that HIDs now have to be whitelisted, like
every other USB device for OH0 and VEN.
libusb on Windows is limited to only a single context. Trying to open
more than one can cause device enumerations to fail randomly.
libusb is thread-safe and we don't use the manual polling support (with
`poll()`) so this should be safe.
The Host class will be used by the OH0, VEN and HID implementations
as the base class for the IOS HLE device. It handles scanning devices,
detecting device changes and everything that will be needed for OH0,
VEN and HID to be implemented, while mostly abstracting libusb away.
The Device class is for actual USB devices. This commit adds a
LibusbDevice which interacts with a real USB device and enables
USB passthrough.
The NullAudio backend is guaranteed to be compiled in, so no reason
to check it.
In addition to that, if it wasn't valid, it wouldn't work as a fallback
in InitSoundStream as there are uses to g_sound_stream later.
Keeps associated data together. It also eliminates the possibility of out
parameters not being initialized properly. For example, consider the
following example:
-- some FramebufferManager implementation --
void FBMgrImpl::GetTargetSize(u32* width, u32* height) override
{
// Do nothing
}
-- somewhere else where the function is used --
u32 width, height;
framebuffer_manager_instance->GetTargetSize(&width, &height);
if (texture_width != width) <-- Uninitialized variable usage
{
...
}
It makes it much more obvious to spot any initialization issues, because
it requires something to be returned, as opposed to allowing an
implementation to just not do anything.
Movie basically just wants to get the title ID of
the initally booted game, so let's set the title ID in
ConfigManager at boot like we do with the regular game ID.
Aside from being cleaner, this should make the approach to
title IDs compatible with booting non-disc software (WADs).
This is unnecessary now that IOS::HLE is responsible for writing the
values to memory; removing the writes also prevents the IOS minor
version from being mangled (by the write to 0x3142).
Instead of using install() commands, we use the MACOSX_PACKAGE_LOCATION
property, which will allow the files to be identified and updated individually
by the build system without having to remove the entire folder and copy it
each time.
deploy-mac.py is now idempotent and should be working properly, so we'll
call it all the time from now on.
On macOS, we want them copied in the bundle directly, otherwise we will
install them later in the system folder.
Obviously not working for Windows, but that's not any different from before!
Forward declaring functions from a completely different header inside a cpp
file can lead to linker errors. Forward declaring also doesn't really
provide any benefit within cpp files unless it's to bring an internally
linked function within the same file into scope.
Hopefully will fix the crash in vkDestroyInstance on the NV Shield TV,
and likely reduce boot times slightly for drivers that take a while
to create instances.
Makes it more self-documenting which stack is being loaded or stored to,
as C, D, and magic numbers are extremely vague. It also enforces a
strongly-typed API instead of accepting arbitrary integral values.
It also adds the two other missing stack register names -- loop address
and loop counter.
This fixes a crash when trying to open the advanced input config dialog on the wiimote extensions. The device_cbox wasn't initialised and it should have been with the wiimote one.
These quite clearly have a dependency on the emitter itself, so these
should be a part of the emitter itself.
The template function can be modified to just simply take functions as a
parameter.
