Subject: [PATCH v14 00/17] HID: nintendo
Date: Sat, 24 Jul 2021 23:26:50 -0400 [thread overview]
Message-ID: <20210725032707.440071-1-djogorchock@gmail.com> (raw)
I've updated the driver to use the "player" string introduced in
Roderick's pending patch. I'll update the series again if that pending
patch is altered or a different approach is decided on.
Some stability improvements are included as well.
Version 14 changes:
- Use proper LED classdev name scheme
- Prevent situations where a missed zero amplitude rumble packet would
leave the controller stuck vibrating until a timeout
- Introduce a max rate at which subcommands or rumble packets can be
sent to the controller. This reduces bluetooth disconnects.
- Send rumble packets immediately after receiving input reports. This
reduces bluetooth disconnects (similar technique was already used
for subcommands).
Version 13 changes:
- Switched to using the dedicated rumble data message type, rather
than constantly resending the rumble enabled subcommand. This more
closely resembles how the console itself handles rumble data.
- Applied revisions based on Silvan Jegen's feedback on v12.
Version 12 changes:
- Added support for reading user calibration from the controller's
SPI flash (written when someone calibrates the controller on the
Nintendo switch).
- Added patch to prevent sending rumble subcommands when no effect
is being played. This turned out to drastically improve bluetooth
connection reliability.
- Set the battery description to POWER_SUPPLY_TYPE_BATTERY (was
missing in previous revisions due to oversight). This fixes problems
with desktop environments not handling the controller batteries
properly.
- Reintroduced IMU patch with improvements to documentation, packet
drop handling, and increased precision for gyro readings. Also
now blacklists the IMU input dev from joydev like hid-sony.
Version 11 changes:
- Removed IMU patch for now, since it has some issues to work out.
- Fixed bug introduced in v10 which led to the joy-cons' S-triggers
not being configured as an input.
- Changed the pro controller's d-pad input from buttons to a hat to be
more in line with other controller drivers.
Version 10 changes:
- Removed duplicate reporting of one of the triggers that Billy noticed
- The joy-cons now only report having the buttons they actually have
(they used to register the input devices with the buttons of the
other joy-con as well).
- The input device is now created after the LEDs/power supply.
- The removed state handling bool has been removed, instead opting to
add a new controller state (removed).
- Eliminated a 1 second delay when probing a USB controller.
- Added support for the IMU. This mostly consisted of merging in some
work provided by Carl. I'm not incredibly familiar with proper
gyro/accelerometer handling in linux, so this might need some
tweaking. Preliminary tests in evtest show the gyro/accel values
being reported.
- Added support for the joy-con USB charging grip.
Version 9 changes:
- Fixed compiler errors on gcc versions older than 8.2
- Set input device's uniq value to the controller's MAC address
Version 8 changes:
- Corrected the handshaking protocol with USB pro controllers. A
handshake now occurs both prior and after the baudrate set. This
doesn't appear to have a noticeable difference, but it more
accurately follows documentation found online.
- Fixed potential race condition which could lead to a slightly longer
delay sending subcommands in rare circumstances.
- Moved the rumble worker to its own workqueue, since it can block.
This prevents it from having a negative impact on the default kernel
workqueue. It also prevents dropped subcommands due to something
else blocking the kernel workqueue. The benefit is most obvious when
using multiple controllers at once, since the controller subcommand
timings are very picky.
- Added a patch to set the most significant bit of the hid hw version.
Roderick had mentioned needing to probably do this awhile ago, but I
had forgotten about it until now. This is the same thing hid-sony
does. It allows SDL2 to have different mappings for the hid-nintendo
driver vs the default hid mappings.
Version 7 changes:
- Changed name to hid-nintendo to fit modern naming conventions
- Removed joycon_ctlr_destroy(), since it wasn't needed an could
potentially invalidate a mutex while it could be in use on other
threads
- Implemented minor code improvements suggested by Silvan
- The driver now waits to send subcommands until after receiving an
input report. This significantly reduces dropped subcommands.
- Reduced the number of error messages when disconnecting a
controller.
Version 6 changes:
- Improved subcommand sending reliabilty
- Decreased rumble period to 50ms
- Added rumble queue to avoid missing ff_effects if sent too quickly
- Code cleanup and minor refactoring
- Added default analog stick calibration
Version 5 changes:
- Removed sysfs interface to control motor frequencies.
- Improved rumble reliability by using subcommands to set it.
- Changed mapping of the SL/SR triggers on the joy-cons to map to
whichever triggers they lack (e.g. a left joycon's sl/sr map to
TR and TR2). This allows userspace to distinguish between the
normal and S triggers.
- Minor refactors
Version 4 changes:
- Added support for the Home button LED for the pro controller and
right joy-con
- Changed name from hid-switchcon to hid-joycon
- Added rumble support
- Removed ctlr->type and use hdev->product instead
- Use POWER_SUPPLY_CAPACITY_LEVEL enum instead of manually translating
to capacity percentages
- Misc. minor refactors based on v3 feedback
Version 3 changes:
- Added led_classdev support for the 4 player LEDs
- Added power_supply support for the controller's battery
- Made the controller number mutex static
- Minor refactoring/style fixes based on Roderick's feedback from v2
Version 2 changes:
- Switched to using a synchronous method for configuring the
controller.
- Removed any pairing/orientation logic in the driver. Every
controller now corresponds to its own input device.
- Store controller button data as a single u32.
- Style corrections
