- improvement of the way hid-bpf coexists with specific drivers (others than hid-generic) that are already bound to devices (Benjamin Tissoires)
2024-10-04HID: add per device quirk to force bind to hid-genericBenjamin Tissoires
We already have the possibility to force not binding to hid-generic and rely on a dedicated driver, but we couldn't do the other way around. This is useful for BPF programs where we are fixing the report descriptor and the events, but want to avoid a specialized driver to come after BPF which would unwind everything that is done there.

2024-10-02move asm/unaligned.h to linux/unaligned.hAl Viro
asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

2018-04-26HID: generic: create one input report per application typeBenjamin Tissoires
It is not a good idea to try to fit all types of applications in the same input report. There are a lot of devices that are needing the quirk HID_MULTI_INPUT but this quirk doesn't match the actual HID description as it is based on the report ID. Given that most devices with MULTI_INPUT I can think of split nicely the devices inputs into application, it is a good thing to split the devices by default based on this assumption. Also make hid-multitouch following this rule, to not have to deal with too many input created. While we are at it, fix some checkpatch complaints about converting 'unsigned' to 'unsigned int'.

2018-03-06HID: core: rewrite the hid-generic automatic unbindBenjamin Tissoires
We actually can have the unbind/rebind logic in hid-core.c, leaving only the match function in hid-generic. This makes hid-generic simpler and the whole logic simpler too. Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2017-11-21HID: core: remove the absolute need of hid_have_special_driver[]Benjamin Tissoires
Most HID devices behave properly when they are used with hid-generic. Since kernel v4.12, we do not poll for input reports at plug in, so hid-generic should behave properly with all HID devices. There has been a long standing list of HID devices that have a special driver. It used to be just a few, but with time, this list went too big, and we can not ask users to know which HID special driver will pick up their device. We can teach hid-generic to be nice with others. If a device is not explicitly marked with HID_QUIRK_HAVE_SPECIAL_DRIVER, we can allow hid-generic to pick up the device as long as no other loaded HID driver will match the device. When the special driver appears, hid-generic can step back and let the special driver handling the device. In case this special driver is removed, this good old pal of hid-generic will rebind to the device. This basically makes the list hid_have_special_driver[] useless. It still allows to not see a hid-generic driver bound and removed during boot, so we can keep it around. This will also help other people to have a special HID driver without the need of recompiling hid-core.

2013-01-03HID: Use module_hid_driver macroH Hartley Sweeten
Use the new module_hid_driver macro in all HID drivers that have a simple register/unregister init/exit. This also converts the hid drivers that test for a failure of hid_register_driver() and report the failure. Using module_hid_driver in those drivers removes the failure message.

2012-05-01HID: Create a common generic driverHenrik Rydberg
Move the hid drivers of the bus drivers to a common generic hid driver, and make it a proper module. This ought to simplify device handling moving forward. Cc: Gustavo Padovan <gustavo@padovan.org> Signed-off-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
