Add missing newlines to logging messages where necessary. Coalesce format strings. Add and use pr_fmt(fmt) KBUILD_MODNAME ": " fmt Other miscellaneous changes: Add const struct hid_device * argument to hid-core functions extract() and implement() so hid_<level> can be used by them.

* | input: mt: Move tracking and pointer emulation to input-mtHenrik Rydberg2010-12-161-28/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The drivers using the type B protocol all report tracking information the same way. The contact id is semantically equivalent to ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates the driver. The situation can be improved upon by providing a common pointer emulation code, thereby removing the need for the tracking id in the driver. This patch moves all tracking event handling over to the input core, simplifying both the existing drivers and the ones currently in preparation.

* | input: mt: Collect slots initialization codeHenrik Rydberg2010-12-161-4/+1
| | | | | | | | | | | | | | | | | | The MT slots devices all follow the same initialization pattern of creating slots and hinting about buffer size. Let drivers call an initialization function instead, and make sure it can be called repeatedly without side effects. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
* | input: mt: Break out slots handlingHenrik Rydberg2010-12-161-0/+1
|/ | | | | | | In preparation for common code to handle a larger set of MT slots devices, move the slots handling over to a separate file. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
* HID: 3m: Adjust major / minor axes to scaleHenrik Rydberg2010-09-221-4/+6
| | | | | | | | | | By visual inspection, the reported touch_major and touch_minor axes are a factor of two too large. Presumably the device actually reports the width_major and width_minor, which are generally about a factor of two larger than the touches themselves.

* HID: 3m: Correct touchscreen emulationHenrik Rydberg2010-09-211-36/+5
| | | | | | | | | | | | The current code sometimes misses to report the last BTN_TOUCH event when multiple fingers are lifted simultaneously. With the introduction of MT slots, the tracking id is available to determine the oldest active contact. Use this information to simplify and correct the touchscreen emulation logic.

* HID: 3m: Convert to MT slotsHenrik Rydberg2010-09-211-11/+43
| | | | | | | | | | | The Microtouch controller is capable of doing finger tracking on up to 60 fingers. To reduce bandwidth and cpu usage, convert the driver to use the MT slots protocol. On Stephane's suggestion, also insert the additional copyright lines.

* HID: 3m: Output proper orientation rangeHenrik Rydberg2010-09-211-1/+1
| | | | | | | | | | The range of orientation values for height/width devices should be [0, 1], but is currently set to [1, 1]. Having min == max also breaks uinput device setup.

* HID: 3m: Adjust to sequential MT HID protocolHenrik Rydberg2010-09-211-4/+18
| | | | | | | | | | | | The multitouch extensions to the HID protocol allows for contact data to be sent over several reports, which is also the case for the 3M M2256PW touchscreen. This patch modifies the logic to only synchronize the input layer when all contacts have been received. Consequentially, the full 60-finger capacity of the device is enabled.

| | | | | | | | | | | | | | | | | | | | | | | | Now support the 22" display and its updated firmware, including touch width and height. The number of touches can now go up to 60, and our single touch emulation will fail when there are more than 6-7 touches; further work is needed on this.

* | 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.
