2010-09-06Input: cy8ctmg110 - add fuzz to ABS_X and ABS_Y to remove jitterJames Ketrenos1-2/+2

2010-09-05Input: wacom - add a quirk for low resolution Bamboo devicesHenrik Rydberg2-0/+11
The Bamboo Touch reports a sub-screen resolution of 480x320. The signal-to-noise ratio is only about 100, so filtering is needed in order to reduce the jitter to a usable level. However, the low resolution leads to round-off errors in the EWMA filter, resulting in extremely jerky pointer motion. This patch explicitly sets a higher resolution for those devices, and tells this to the completion handler via a low-resolution quirk.

2010-09-01Staging: mrst-touchscreen - fix channel allocationArjan van de Ven1-17/+12
The touch screen driver tries to find a range of free channels (which are an array of bytes), by scanning for the "end of used channel" marker. However it tries to be WAAAAY too smart and does 32 bit logic on 8 bit quantities, and in the process completely gets it wrong (repeatedly read the same register instead of incrementing in the loop, assuming that if any of the 4 bytes in the 32 byte quantity is free, all four are free, returning the channel number divided by 4 rather than the actual first free channel number) On the setting side, the same mistakes are made by and large; changed this to just use the byte SCU write functions.... With these fixes we go from a completely non detected touchscreen to something that appears to completely get detected.

2010-08-31Input: i8042 - fix device removal on unloadDmitry Torokhov1-1/+1
We need to call platform_device_unregister(i8042_platform_device) before calling platform_driver_unregister() because i8042_remove() resets i8042_platform_device to NULL.

2010-08-28Input: wacom_w8001 - add multitouch slot supportPeter Hutterer1-3/+46
Some serial wacom devices support two-finger touch. Test for this during init and parse the touch packets accordingly. Touch packets are processed using Protocol B (MT Slots). Note: there are several wacom versions that do touch but not two-finger touch. These are not catered for here, touch events for these are simply discarded.

2010-08-28Input: wacom_w8001 - send BTN_TOOL_PEN/RUBBER and BTN_STYLUS eventsPeter Hutterer1-6/+48
The protocol used by the w8001 supports status fields for tip, side switch and eraser as well as a RDY field for proximity. The protocol has a double usage for the f2 bit in the packet. If set, the data is either pen + side2 button or eraser. Assume eraser if the device comes into proximity with the f2 bit set, otherwise trigger the side2 button. If the device comes into proximity with the f2 bit and that bit disappears afterwards, fake proximity out for the eraser and proximity in for the pen.

2010-08-28Input: MT - initialize slots to unusedHenrik Rydberg1-2/+9

2010-08-28Input: use PIT_TICK_RATE in vt beep ioctlArnd Bergmann1-8/+8
The KIOCSOUND and KDMKTONE ioctls are based on the CLOCK_TICK_RATE, which is architecture and sometimes configuration specific. In practice, most user applications assume that it is actually defined as the i8253 PIT base clock of 1193182 Hz, which is true on some architectures but not on others. This patch makes the vt code use the PIT frequency on all architectures, which is much more well-defined. It will change the behavior of user applications sending the beep ioctl on all architectures that define CLOCK_TICK_RATE different from PIT_TICK_RATE. The original breakage was introduced in commit bcc8ca099 "Adapt drivers/char/vt_ioctl.c to non-x86". Hopefully, reverting this change will make the frequency correct in more cases than it will make it incorrect.

2010-08-28Input: wacom - fix mousewheel handling for old wacom tabletsMike Auty1-2/+2
This fixes a regression introduced in 3b57ca0f80c5c8994b5b1e3d3f904cfe727951f2. The data[6] byte contains either 1 or -1 depending on the whether the mouse wheel on older wacom tablets is moved down (1) or up (-1). The patch introduced in the above commit changed the cast from (signed char) to (signed). When cast as a signed integer and negated, the value of -1 (stored in the byte as 0xff) became -255 rather than 1. This patch reverts the cast to a (signed char) and also removes an unnecessary (signed) cast, as all the values operated on are bitmasked.

Recent modprobe and udev versions allow to create device nodes for modules which are not loaded. Only the first access will cause the in-kernel module loader to pull-in the module.

2010-08-15mm: fix up some user-visible effects of the stack guard pageLinus Torvalds2-1/+15
This commit makes the stack guard page somewhat less visible to user space. It does this by: - not showing the guard page in /proc/<pid>/maps It looks like lvm-tools will actually read /proc/self/maps to figure out where all its mappings are, and effectively do a specialized "mlockall()" in user space. By not showing the guard page as part of the mapping (by just adding PAGE_SIZE to the start for grows-up pages), lvm-tools ends up not being aware of it. - by also teaching the _real_ mlock() functionality not to try to lock the guard page. That would just expand the mapping down to create a new guard page, so there really is no point in trying to lock it in place. It would perhaps be nice to show the guard page specially in /proc/<pid>/maps (or at least mark grow-down segments some way), but let's not open ourselves up to more breakage by user space from programs that depends on the exact deails of the 'maps' file. Special thanks to Henrique de Moraes Holschuh for diving into lvm-tools source code to see what was going on with the whole new warning.
