From 606df97b6a2438a8844c828ecdef1e9b25e2e838 Mon Sep 17 00:00:00 2001 From: Peter Hutterer Date: Thu, 26 Mar 2015 14:08:35 +1000 Subject: udev: input_id: tag pointing sticks as ID_INPUT_POINTINGSTICK Also referred to as trackpoint, trackstick. These are marked by recent kernels through an input prop. Forward that prop as udev property so userspace can easily determine whether there is a pointing stick present. These devices were previously marked as ID_INPUT_MOUSE, for backwards compatibility we keep that in place, the new property is an addition. --- src/udev/udev-builtin-input_id.c | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) (limited to 'src/udev/udev-builtin-input_id.c') diff --git a/src/udev/udev-builtin-input_id.c b/src/udev/udev-builtin-input_id.c index 46f1c539d2..d4c38cae6e 100644 --- a/src/udev/udev-builtin-input_id.c +++ b/src/udev/udev-builtin-input_id.c @@ -131,6 +131,7 @@ static void test_pointers (struct udev_device *dev, const unsigned long* bitmask_abs, const unsigned long* bitmask_key, const unsigned long* bitmask_rel, + const unsigned long* bitmask_props, bool test) { int is_mouse = 0; int is_touchpad = 0; @@ -173,6 +174,9 @@ static void test_pointers (struct udev_device *dev, udev_builtin_add_property(dev, test, "ID_INPUT_JOYSTICK", "1"); } + if (test_bit (INPUT_PROP_POINTING_STICK, bitmask_props)) + udev_builtin_add_property(dev, test, "ID_INPUT_POINTINGSTICK", "1"); + if (test_bit (EV_REL, bitmask_ev) && test_bit (REL_X, bitmask_rel) && test_bit (REL_Y, bitmask_rel) && test_bit (BTN_MOUSE, bitmask_key)) @@ -232,6 +236,7 @@ static int builtin_input_id(struct udev_device *dev, int argc, char *argv[], boo unsigned long bitmask_abs[NBITS(ABS_MAX)]; unsigned long bitmask_key[NBITS(KEY_MAX)]; unsigned long bitmask_rel[NBITS(REL_MAX)]; + unsigned long bitmask_props[NBITS(INPUT_PROP_MAX)]; const char *sysname, *devnode; /* walk up the parental chain until we find the real input device; the @@ -248,7 +253,9 @@ static int builtin_input_id(struct udev_device *dev, int argc, char *argv[], boo get_cap_mask(dev, pdev, "capabilities/abs", bitmask_abs, sizeof(bitmask_abs), test); get_cap_mask(dev, pdev, "capabilities/rel", bitmask_rel, sizeof(bitmask_rel), test); get_cap_mask(dev, pdev, "capabilities/key", bitmask_key, sizeof(bitmask_key), test); - test_pointers(dev, bitmask_ev, bitmask_abs, bitmask_key, bitmask_rel, test); + get_cap_mask(dev, pdev, "properties", bitmask_props, sizeof(bitmask_props), test); + test_pointers(dev, bitmask_ev, bitmask_abs, bitmask_key, + bitmask_rel, bitmask_props, test); test_key(dev, bitmask_ev, bitmask_key, test); } -- cgit v1.2.3
