* Input: sentelic - silence some underflow warningsDan Carpenter2015-08-211-6/+8
| | | | | | | | | | | I have a static checker that complains when we check for an upper bound but don't have a corresponding check for a lower bound. With this code, the upper bound check seems not really required, so it is not a bug to leave the lower bound check out as well. But let's silence the warning by making these variables unsigned.

* Input: sentelic - only report position of first finger as ST coordinatesChristophe TORDEUX2012-12-241-1/+1
| | | | | | | | | | | | Report only the position of the first finger as absolute non-MT coordinates, instead of reporting both fingers alternatively. Actual MT events are unaffected. This fixes horizontal and improves vertical scrolling with the touchpad.

* | Input: sentelic - filter out erratic movement when lifting fingerTai-hwa Liang2012-09-191-0/+11
|/ | | | | | | | | | | | | | | | When lifing finger off the surface some versions of touchpad send movement packets with very low coordinates, which cause cursor to jump to the upper left corner of the screen. Let's ignore least significant bits of X and Y coordinates if higher bits are all zeroes and consider finger not touching the pad.

| | | | | | | | | | | | Hardware since Cx supports an unique identity (used to identify OEM vendors and released lot number) which is very helpful for diagnostic purpose.

* Input: sentelic - filter taps in absolute modeOskari Saarenmaa2012-04-031-0/+8
| | | | | | | | | | | | | | Taps in absolute positioning single-finger mode are currently reported as physical clicks by the driver. This should be handled by userspace, not the kernel. When a tap occurs, the FSP_PB0_LBTN bit is set, but the FSP_PB0_PHY_BTN is not. We use this to filter out physical clicks from taps.

* Input: sentelic - enabling absolute coordinates output for newer hardwareTai-hwa Liang2012-03-251-3/+111
| | | | | | | | | | | | | | | | | | - Hooking multi-finger coordinates output with kernel multitouch library; - Enabling absolute coordinates output for Cx+ hardware. The older hardware performs much better in relative mode; thus relative mode related code are preserved. Part of the code is based on the work done by Oskari Saarenmaa <os@ohmu.fi>, which was used to support the clickpad found on ASUS UX21/31 Ultrabook. On the other hand, the FSP found on UX21/31 doesn't have hardware capability register other than PnP ID, which means that we'll have to figure out an alternative approach to identify such pad correctly; otherwise, blindly adding INPUT_PROP_BUTTONPAD property may compatability issues amongst existing FSPs.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* Input: libps2 - additional locking for i8042 portsDmitry Torokhov2009-09-171-8/+10
| | | | | | | | | | | | | | | | | The serio ports on i8042 are not completely isolated; while we provide enough locking to ensure proper serialization when accessing control and data registers AUX and KBD ports can still have an effect on each other on PS/2 protocol level. The most prominent effect is that issuing a command for the device connected to one port may cause abort of the command currently executing by the device connected to another port. Since i8042 nor serio subsystem are not aware of the details of the PS/2 protocol (length of the commands and their replies and so on) the locking should be done on libps2 level by adding special handling when we see that we are dealing with serio port on i8042.
