* Input: MT - initialize slots to unusedHenrik Rydberg2010-08-29
| | | | | | | | | For MT slots, the ABS_MT_TRACKING_ID determines whether a slot is in use, but currently leaves initialization up to the drivers. This patch sets the slot state to unused upon creation. Signed-off-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
* Input: dynamically allocate ABS informationDaniel Mack2010-08-02
| | | | | | | | | | As all callers are now changed to only use the input_abs_*() access helpers, switching over to dynamically allocated ABS information is easy. This reduces size of struct input_dev from 3152 to 1640 on 64 bit architectures. Signed-off-by: Daniel Mack <daniel@caiaq.de> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
* Input: switch to input_abs_*() access functionsDaniel Mack2010-08-02
| | | | | | | | | | | | Change all call sites in drivers/input to not access the ABS axis information directly anymore. Make them use the access helpers instead. Also use input_set_abs_params() when possible. Did some code refactoring as I was on it.

* Input: introduce MT event slotsHenrik Rydberg2010-07-16
| | | | | | | | | | | | | | | | | | | | | With the rapidly increasing number of intelligent multi-contact and multi-user devices, the need to send digested, filtered information from a set of different sources within the same device is imminent. This patch adds the concept of slots to the MT protocol. The slots enumerate a set of identified sources, such that all MT events can be passed independently and selectively per identified source. The protocol works like this: Instead of sending a SYN_MT_REPORT event immediately after the contact data, one sends an ABS_MT_SLOT event immediately before the contact data. The input core will only emit events for slots with modified MT events. It is assumed that the same slot is used for the duration of an initiated contact.

* | include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: implement input filtersDmitry Torokhov2010-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes it is desirable to suppress certain events from reaching input handlers and thus user space. One such example is Mac mouse button emulation code which catches certain key presses and converts them into button clicks as if they were emitted by a virtual mouse. The original key press events should be completely suppressed, otherwise user space will be confused, and while keyboard driver does it on its own evdev is blissfully unaware of this arrangement. This patch adds notion of 'filter' to the standard input handlers, which may flag event as filtered thus preventing it from reaching other input handlers. Filters don't (nor will they ever) have a notion of priority relative to each other, input core will run all of them first and any one of them may mark event as filtered. This patch is inspired by similar patch by Matthew Garret but the implementation and intended usage are quite different. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

* Input: add detailed multi-touch finger data report protocolHenrik Rydberg2009-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to utilize the full power of the new multi-touch devices, a way to report detailed finger data to user space is needed. This patch adds a multi-touch (MT) protocol which allows drivers to report details for an arbitrary number of fingers. The driver sends a SYN_MT_REPORT event via the input_mt_sync() function when a complete finger has been reported. In order to stay compatible with existing applications, the data reported in a finger packet must not be recognized as single-touch events. In addition, all finger data must bypass input filtering, since subsequent events of the same type refer to different fingers. A set of ABS_MT events with the desired properties are defined. The events are divided into categories, to allow for partial implementation. The minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked. If the device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide the size of the approaching finger. Anisotropy and direction may be specified with ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and ABS_MT_ORIENTATION. Devices with more granular information may specify general shapes as blobs, i.e., as a sequence of rectangular shapes grouped together by a ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE may be used to specify whether the touching tool is a finger or a pen. Signed-off-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it.
