Pokechu22 558de04cfc Common/Assert: Actually use the ASSERT_MSG's log type parameter
Since it was unused, nonexistent values were used in a few places.  I've replaced them.

Filoppi 81092cf7e4 InputCommon: replace SerialInterface log with ControllerInterface

Dentomologist 1fd332d3b7 ControllerInterface: Fix unused-result warning
Add ! before unused variables to 'use' them.

Ubuntu-x64 emits warnings for unused variables because gcc decides
it should ignore the void cast around them. See thread for discussion:

Jordan Woyak ac907ef977 ControllerInterface: Combine evdev devices with the same unique ID.
This works around Linux drivers for DS4 (Playstation 4) controllers splitting the device into three separate event nodes which makes configuration difficult.
To prevent collisions of input names in combined devices more descriptive names are now used when possible.

Document the evdev "interesting" heuristic
Was checking over this old code, and saw a comment calling me out for a lack of documentation.

Lioncash 50a476c371 Assert: Uppercase assertion macros
Macros should be all upper-cased. This is also kind of a wart that's

Léo Lam 6a93223283 evdev: Always unref received udev devices
Whenever udev_monitor_receive_device() returns a non-null pointer,
the device must be unref'd after use with udev_device_unref().

We previously missed some unref calls for non-evdev devices.

Léo Lam 9a3705f82d evdev: Fix select() call
It's not guaranteed that the eventfd is smaller than the monitor fd,
because fds are not always monotonically allocated. To select()
correctly in all cases, use the max between the monitor fd and eventfd.

Scott Pleb 0bede93daa evdev: Correctly calculate axis range for min values greater than 0.
Axis range was previously calculated as max + abs(min), which relies on the assumption that
min will not exceed 0. For (min, max) values like (0, 255) or (-128, 127), which I assume to
be the most common cases, the range is correctly calculated as 255. However, given (20,
235), the range is erroneously calculated as 255, leading to axis values being normalized
incorrectly.

SDL already handles this case correctly. After changing the range calculation to max - min,
the axis values received from the evdev backend are practically identical to the values
received from the SDL backend.

Lioncash 696e1b40b5 Common: Move version strings to their own header
Ideally Common.h wouldn't be a header in the Common library, and instead be renamed to something else, like PlatformCompatibility.h or something, but even then, there's still some things in the header that don't really fall under that label

This moves the version strings out to their own version header that doesn't dump a bunch of other unrelated things into scope, like what Common.h was doing.

This also places them into the Common namespace, as opposed to letting them sit in the global namespace.

Tillmann Karras 57a005ff3e evdev: reduce startup time
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.

safe to be called multiple times.

Michael Maltese 3e69d066f5 ControllerInterface: replace Reinitialize with RefreshDevices
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.

Léo Lam 135641404a evdev: Add hotplugging support
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).

Léo Lam 788e19f54d ControllerInterface: Make the ID assigning code common
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.

Léo Lam 6cc4591226 evdev: Clamp axis values to the 0.0-1.0 range
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.

Léo Lam 8678133e87 ControllerInterface: Switch to std::shared_ptr
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.

Léo Lam fd29e5c4cc ControllerInterface: Don't pass m_devices to the backends
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.
