From 4749b0a28feddeaeffa8044cd3ae1711cc15c8da Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sun, 23 Jul 2017 17:26:19 +0100 Subject: input: tsc2007 - drop the driver_module assignment in iio interface. This is now handled via some macro magic during the register. The field in iio_info will be removed shortly.

So far, there's been no reason to change most existing uses of ACCESS_ONCE(), as these aren't harmful, and changing them results in churn. However, for some features, the read/write distinction is critical to correct operation. To distinguish these cases, separate read/write accessors must be used. This patch migrates (most) remaining ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following coccinelle script: ---- // Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and // WRITE_ONCE() // $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch virtual patch @ depends on patch @ expression E1, E2; @@ - ACCESS_ONCE(E1) = E2 + WRITE_ONCE(E1, E2) @ depends on patch @ expression E; @@ - ACCESS_ONCE(E) + READ_ONCE(E) ---- Signed-off-by: Mark Rutland Signed-off-by: Paul E.

These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

Conversion was done with the following scripts: perl -pi -e 's|\(TIMER_FUNC_TYPE\)||g' \ $(git grep TIMER_FUNC_TYPE | cut -d: -f1 | sort -u) perl -pi -e 's|\(TIMER_DATA_TYPE\)||g' \ $(git grep TIMER_DATA_TYPE | cut -d: -f1 | sort -u) The now unused macros are also dropped from include/linux/timer.h.

This product has five "buttons" (one of which is the click action on the first wheel) and TWO scroll wheels. However for a byte comprising d0-d7 instead of setting one of d6-7 in the forth byte of the mouse data packet and a twos complement number of scroll steps in the remaining d5-d0 (or d3-d0 should there be a fourth (BTN_SIDE - d4) or fifth (BTN_EXTRA - d5) button to report; they only report a single +/- event for each wheel and use a bit pattern that corresponds to +/-1 for the first wheel and +/- 2 for the second in the lower nibble of the fourth byte. The effect with existing code is that the second mouse wheel merely repeats the effect of the first but providing two steps per click rather than the one of the first wheel - so there is no HORIZONTAL scroll wheel movement detected from the device as far as the rest of the kernel sees it. This patch, if enabled by the "a4tech_workaround" module parameter modifies the handling just for mice of type PSMOUSE_IMEX so that the second scroll wheel movement gets correctly reported as REL_HWHEEL events. Should this module parameter be activated for other mice of the same PSMOUSE_IMEX type then it is possible that at the point where the mouse reports more than a single movement step the user may start seeing horizontal rather than vertical wheel events, but should the movement steps get to be more than two at a time the hack will get immediately deactivated and the behaviour will revert to the past code. This was discussed around *fifteen* *years* *ago* on the LKML and the best summary is in post https://lkml.org/lkml/2002/7/18/111 "Re: PS2 Input Core Support" by Vojtech Pavlik. I was not able to locate any discussion later than this on this topic. Given that most users of the "psmouse" module will NOT want this additional feature enabled I have taken the apparently erroneous step of defaulting the module parameter that enables it to be "disabled" - this functionality may interfere with the operation of "normal" mice of this type (until a large enough scroll wheel movement is detected) so I cannot see how it would want to be enabled for "normal" users - i.e. everyone without this brand of mouse. I am using this patch at the moment and I can confirm that it is working for me as both a module and compiled into the kernel for my mouse that is of the type (WOP-35) described - I note that it is still available from certain on-line retailers and that the manufacturers site does not list GNU/Linux as being supported on the product page - this patch however does enable full use of this product: http://www.a4tech.com/product.asp?cid=3D1&scid=3D8&id=3D22 Signed-off-by: Stephen Lyons Signed-off-by: Dmitry Torokhov --- drivers/input/mouse/psmouse-base.c | 19 +++++++++++++++++-- 1 file changed, 17 insertions(+), 2 deletions(-) (limited to 'drivers/input') diff --git a/drivers/input/mouse/psmouse-base.c b/drivers/input/mouse/psmouse-base.c index 074bc647509d..f0b16eb4a32a 100644 --- a/drivers/input/mouse/psmouse-base.c +++ b/drivers/input/mouse/psmouse-base.c @@ -70,6 +70,10 @@ static bool psmouse_smartscroll = true; module_param_named(smartscroll, psmouse_smartscroll, bool, 0644); MODULE_PARM_DESC(smartscroll, "Logitech Smartscroll autorepeat, 1 = enabled (default), 0 = disabled."); +static bool psmouse_a4tech_2wheels; +module_param_named(a4tech_workaround, psmouse_a4tech_2wheels, bool, 0644); +MODULE_PARM_DESC(a4tech_workaround, "A4Tech second scroll wheel workaround, 1 = enabled, 0 = disabled (default)."); + static unsigned int psmouse_resetafter = 5; module_param_named(resetafter, psmouse_resetafter, uint, 0644); MODULE_PARM_DESC(resetafter, "Reset device after so many bad packets (0 = never)."); @@ -150,6 +154,7 @@ psmouse_ret_t psmouse_process_byte(struct psmouse *psmouse) { struct input_dev *dev = psmouse->dev; u8 *packet = psmouse->packet; + int wheel; if (psmouse->pktcnt < psmouse->pktsize) return PSMOUSE_GOOD_DATA; @@ -175,8 +180,18 @@ psmouse_ret_t psmouse_process_byte(struct psmouse *psmouse) break; case 0x00: case 0xC0: - input_report_rel(dev, REL_WHEEL, - -sign_extend32(packet[3], 3)); + wheel = sign_extend32(packet[3], 3); + + /* + * Some A4Tech mice have two scroll wheels, with first + * one reporting +/-1 in the lower nibble, and second + * one reporting +/-2. + */ + if (psmouse_a4tech_2wheels && abs(wheel) > 1) + input_report_rel(dev, REL_HWHEEL, wheel / 2); + else + input_report_rel(dev, REL_WHEEL, -wheel); + input_report_key(dev, BTN_SIDE, BIT(4)); input_report_key(dev, BTN_EXTRA, BIT(5)); break; -- cgit v1.2.3 From d5e0d9187abd5e3ce23884c375c4b36f403e42be Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Thu, 4 Jan 2018 11:05:30 -0800 Subject: Input: libps2 - fix switch statement formatting Individual labels of switch statements should have the same indentation level as the switch statement itself.

That means that the device may be transmitting motion or keystroke data, while we expect ACK response. Instead of signaling failure if we see anything but ACK/NAK let's ignore "garbage" response until we see ACK for the command byte (first byte).

charset=UTF-8 Content-Transfer-Encoding: 8bit ALPS v3 and v7 packet formats reports trackstick pressure. This information is already parsed in unused "z" variable. ALPS SS4 S2 devices already reports trackstick pressure as ABS_PRESSURE attribute, therefore reports pressure in the same way also for v3 and v7. This patch also updates parsing v3 pressure information, it is also stored in 7 bits.

As the MUX is disabled for all VAIO machines by the nomux blacklist, the data from touch sensor buttons and touchpad are combined. The protocol used by the buttons is probably similar to the touchpad protocol (both are Synaptics) so both devices get enabled. The controller combines the data, creating a mess which results in random button clicks, touchpad stopping working and lost sync error messages: psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 4 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: issuing reconnect request Add a new i8042_dmi_forcemux_table whitelist with VGN-CS.
