GetName() creates a new evdev device which calls tons of ioctls. But the
main culprit is close() which for input devices appears to be a slow
path in the kernel.
This commit reduces PopulateDevices() by 50% on my laptop, but ~730 ms
is still ridiculously slow for something that isn't needed right away.
The SDL backend crashes when you close a joystick after SDL_Quit has
been called. Some backends don't need to be shutdown and
re-initialized everytime, we can just ask to enumerate devices again.
Rewrite GetXInputGUIDS to use SetupAPI instead of WMI Queries. When
using a language pack where the system language and user/program
language differ, Windows starts taking a VERY long time (10+ seconds)
to complete Queries for Win32_PNPEntity objects (it's probably
translating every single string since it transfers every single one
from the WMI server into memory in the program).
Fixes Issue 9744.
There is no reason to prevent the user from closing the config dialog
if the device is not found. It's not very good UX…
Also fixes ExpressionParser to return NO_DEVICE if the device doesn't
exist instead of SUCCESS.
This adds hotplugging support to the evdev input backend. We use
libudev to monitor changes to input devices in a separate thread.
Removed devices are removed from the devices list, and new devices
are added to the list.
The effect is that controllers are usable immediately after plugging
them without having to manually refresh devices (if they were
configured to be used, of course).
Changes UpdateInput() to skip if we can't lock the mutex, instead of
potentially blocking the CPU thread and causing a short but noticeable
frame drop.
This adds RemoveDevice() to ControllerInterface, fixes ExpressionParser
and some other code to support device removals without crashing,
and adds an IsValid() method to Device, to prepare for hotplugging.
This adds RegisterHotplugCallback() to register a callback which will
be invoked by the input backends' hotplug threads when there is a new
device, so that Core (GCKeyboard, GCPad, Wiimote, Hotkey) can reload
the configuration without adding a dependency to Core from InputCommon.
This makes the device ID assigning code common to all backends, by
moving it to AddDevice() instead of copy-pasting or replicating
the logic in the backends.
Also, to prepare for hotplugging, instead of relying on a name usage
count, the new ID assigning system always starts from ID 0 and tries
to assign the first ID that is not used.
The values are expected to be in the 0.0-1.0 range (as indicated by the
comment), and other parts of Dolphin also expect it to be in that range
since the "full" axis has a -1.0 to 1.0 range. However, this is not
always the case and fvalue can end up being outside of the range. This
clamps fvalue to always be in the 0.0 and 1.0 range.
Small cleanup by using std::shared_ptr and getting rid of
ciface.Devices() which just returned the m_devices (which defeats the
point of making m_devices protected).
Incidentally, this should make the code safer when we have
different threads accessing devices in the future (for hotplug?).
A lot of code use Device references directly so there is
no easy way to remove FindDevice() and make those unique_ptrs.
Previously, the devices vector would be passed to all backends. They
would then manually push_back to it to add new devices. This was fine
but caused issues when trying to add synchronisation.
Instead, backends now call AddDevice() to fill m_devices so that it is
not accessible from the outside.
Disclaimer: I can't test if this works on xbox one controllers, i don't have one. But i have conformed that this UpdateMotors() is related to rumble for emulated wiimotes.
This partially reverts commit "XInput: Apply immediately as well" (1958a10b6f) from pr # https://github.com/dolphin-emu/dolphin/pull/1560
Hopefully this fixes the xbox one controller rumble issue:
https://bugs.dolphin-emu.org/issues/9071
And in theory it might reduce the used usb bandwidth, as it was originally intended before pr 1560.
@JMC47: Please do a good amount of testing, to see if this breaks rumble for wiimotes or gamecube controllers emulated with xinput devices.
Lets the user set the following in intervals of 10 between 10 and 100;
- Stick/Radius (default 100,000000)
- Triggers/Threshold (default 90,000000)
- Tilt/Modifier/Range (default 50,000000) + mapped Tilt/Modifier button
to the configurations for wiimotes & nunchuks
If there were two commands in the buffer at once, it would only run the
first because of an error in UpdateInput.
If you sent the command "SET C" it would segfault because of a logic
issue in ParseCommand.
Currently only works on unix, but can be extended to other systems. Can
also be extended to do wiimotes.
Searches the Pipes folder for readable named pipes and creates a dolphin
input device out of them. Send controller inputs to the game by writing
to the file. Commands are described in Pipes.h.
Previously, MacOpenFile only overrode anything on OS X; otherwise it was
just a useless method, which is presumably why it wasn't marked override
in the first place. Address this more sanely by wrapping it in #ifdef
__APPLE__.
Using SDL_INIT_JOYSTICK implies SDL_INIT_EVENTS which installs a signal
handler for SIGINT and SIGTERM. There will be a way to prevent this in
2.0.4 but for now we'll need to handle SDL_QUIT.
- Simplified the locking mechanism when controllers were updated
- Reloaded the config of the controls instead of re-initialising the control plugins
- Fixed controls being unresponsive after the Refresh button was pressed
- Disables the hotkeys while the controller config is open
My keyboard layout does not have Alt_R but ISO_Level3_Shift. As a
consequence any control expression containing Alt_R fails to evaluate
completely and is unusable. This modification replace the missing term
of the expression by a dummy expression which always evaluate to
0. This way, the keybinding can work even if some keys are not
available.
We can compile with haptic support, and then not initialize due to haptics not being available.
So if we are compiling with haptics, test initializing with haptics and if that fails attempt to initialize without haptics before bailing out.
I'm not sure when this nonsense of forcing locking the mutex when it's
already taken should have ever taken effect, but let's be thankful it
isn't now. That was a badly worded sentence.
This is good hygiene, and also happens to be required to build Dolphin
using Clang modules.
(Under this setup, each header file becomes a module, and each #include
is automatically translated to a module import. Recursive includes
still leak through (by default), but modules are compiled independently,
and can't depend on defines or types having previously been set up. The
main reason to retrofit it onto Dolphin is compilation performance - no
more textual includes whatsoever, rather than putting a few blessed
common headers into a PCH. Unfortunately, I found multiple Clang bugs
while trying to build Dolphin this way, so it's not ready yet, but I can
start with this prerequisite.)
Initialize now just takes the handle directly. Reinitialize is added because it is much more straightforward in comparison to doing the Shutdown-Initialize manually.
strictStrings is not supported by debug libraries, and indeed breaks the build.
Drop wbemidl.h (incompatible with strictStrings) dependency by using SDL-style search for XInput GUIDs.
Yes, this is a fancy new feature, but our Wayland support was
particularly bitrotten, and ideally this would be handled by a platform
layer like SDL. If not, we can always add this back in when GLInterface
has caught up. We might be able to even support wxWidgets and GL
together with subsurfaces!
It was broken by e15ec56bf0 because it wasn't deemed important. However chances are people will eventually start using Dolphin on that configuration, so we shouldn't frivolously drop compatibility without good reason.
We can't use RendererHasFocus for this purpose because of some issues
with exclusive fullscreen, and the new RendererHasFocus implementation
didn't work for non-Render to Main Window cases, since the renderer
window wasn't managed by wx.
Looking at the old code for the ButtonManager was a brainfsck. This fixes a ton of bugs I kept uncovering as I was moving along.
Fixes the gamepad configuration file being incorrect.
No longer treats touchscreen in a special way. Ends up as a regular device with a "Touchscreen" device name.
Was incorrectly converting a index from integer to ButtonType. Wouldn't work due to the addition of some unused(in JNI) enumerators in ButtonType.
Fixes an issue where a map had a key as an axis which was causing its binding to be overwritten for every axis that was used twice (eg main stick left and right);
Fixes Triggers not working at all.
Fixes DPad not working at all.
Fixes C-Stick only half working.
Removes touch screen specific nativelibrary types onTouchAxisEvent and onTouchEvent.
Adds a configuration version configuration option. Allows easy configuration overwriting if the options need to be changed during updating.
Supersedes github PR #291.
- remove unused variables
- reduce the scope where it makes sense
- correct limits (did you know that strcat()'s last parameter does not
include the \0 that is always added?)
- set some free()'d pointers to NULL
