One such joystick reported to not work properly is Saitek X52 Pro Flight System. We can't extend the range to fit more buttons in, because of backwards compatibility reasons. Therefore this patch introduces a new BTN_TRIGGER_HAPPY range, and uses these to map the buttons which are over BTN_JOYSTICK limit.

Disabling the hard-coded layout solves the problem that the kernel-module only works perfectly for the english/american version of the Apple aluminum keyboard. Other versions have swapped keys, e.g. the "<"-key is swapped with "^"-key on the german keyboard.

Remove the blacklist entry for this combination of VID/PID completely, and let the user decide and unbind the driver via sysfs eventually, if needed. Proper fix would be fixing the vendor.

This has been fixed by 6bf8268f9a91f1 ("Bluetooth: Use the control channel for raw HID reports") Still, it is necessary to distinguish whether the report in question should be either FEATURE or OUTPUT. For this, we have to extend the generic HID API, so that hid_output_raw_report() callback provides means to specify this value so that it can be passed down to lower level hardware drivers (currently Bluetooth and USB).

This has been introduced on Linus' request from 14 Oct === As to the Kconfig options - do they really add so much space that you need to ask for the quirks? You didn't use to. Can you make the questions depend on EMBEDDED, or at least on the HID_COMPAT thing or whatever? === This still makes perfect sense for small and tiny drivers, which just fix report descriptors, fix up HID->input mappings that slightly violates HUT standard, send one extra packet to the device that is needed before it becomes functional, etc. Since then, we have been gathering more and more HID-bus drivers, which are full-fledged drivers. For these, the size argument becomes more valid. Plus the devices are much more special than "just violates HID specification in this one or two tiny unimportant points". Therefore I am marking such drivers as properly selectable no matter the setting of CONFIG_EMBEDDED, while keeping all the small and tiny ones compiled by default.

The Magic Mouse requires that a driver send an unlock Report(Feature) command, similar to the Wacom wireless tablet and Sixaxis controller quirks. This turns on an Input Report that isn't published in the input Report descriptor that contains touch data (and usually overrides the normal motion and click Report). Because the mouse has only one switch and no scroll wheel, the driver (under control of parameters) emulates a middle button and scroll wheel. User space could also ignore and/or re-synthesize those events based on the reported events.

Taps are now explicitly handled to adjust for the changes in the event stream in multitouch mode. Added triple and quad tap for the benefit of tools that recognize different tap types but do not have full multi touch support. This cleans up the behavior particularly for the latest firmware, which didn't work particularly well with the older version of the driver. In this form, when multitouch is active, both mt and st events will come out of the "N-Trig MultiTouch" device. And when its not st events will come out of "N-Trig Touchscreen".

These are due to hid_debug_event() adding strlen()+1 bytes to the ring buffer (e.g. including the trailing '\0'). Any roll-over causes a '\0' as well as hid_debug_event() handles the ring buffers with HID_DEBUG_BUFSIZE-1 size while hid_debug_events_read() handles it with full HID_DEBUG_BUFSIZE size.

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.
