From 001a247324b44c0e0b8fdba41a6fc66e7465b8b6 Mon Sep 17 00:00:00 2001 From: Peter Hutterer Date: Wed, 28 Jan 2015 14:05:01 +1000 Subject: hwdb: add a touchpad hwdb Currently used to tag devices in the new Lenovo *50 series and the X1 Carbon 3rd. These laptops re-introduced the physical trackpoint buttons that were missing from the *40 series but those buttons are now wired up to the touchpad. The touchpad now sends BTN_0, BTN_1 and BTN_2 for the trackpoint. The same button codes were used in older touchpads that had dedicated scroll up/down buttons. Input drivers need to work around this and thus know what they're dealing with. For the previous gen we introduced INPUT_PROP_TOPBUTTONPAD in the kernel, but the resulting mess showed that these per-device quirks should really live in userspace. The list currently includes the X1 Carbon 3rd PNPID, others will be added as get to know which PNPID they have. --- rules/70-touchpad.rules | 12 ++++++++++++ 1 file changed, 12 insertions(+) create mode 100644 rules/70-touchpad.rules (limited to 'rules') diff --git a/rules/70-touchpad.rules b/rules/70-touchpad.rules new file mode 100644 index 0000000000..88e6fd2f25 --- /dev/null +++ b/rules/70-touchpad.rules @@ -0,0 +1,12 @@ +# do not edit this file, it will be overwritten on update + +ACTION=="remove", GOTO="touchpad_end" +KERNEL!="event*", GOTO="touchpad_end" +ENV{ID_INPUT_TOUCHPAD}=="", GOTO="touchpad_end" + +# touchpad:pnpid::* +KERNELS=="serio1", \ + IMPORT{builtin}="hwdb 'touchpad:pnpid:$attr{firmware_id}:'", \ + GOTO="touchpad_end" + +LABEL="touchpad_end" -- cgit v1.2.1
