| | | | | | | | | | | | | | | | | | | | We should only wake waiters on the event device when we actually post an EV_SYN/SYN_REPORT to the queue. Otherwise we end up making waiting threads runnable only to go right back to sleep because the device still isn't readable.

* | Revert "tty: make receive_buf() return the amout of bytes received"Linus Torvalds2011-06-041-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit b1c43f82c5aa265442f82dba31ce985ebb7aa71c. It was broken in so many ways, and results in random odd pty issues. It re-introduced the buggy schedule_work() in flush_to_ldisc() that can cause endless work-loops (see commit a5660b41af6a: "tty: fix endless work loop when the buffer fills up"). It also used an "unsigned int" return value fo the ->receive_buf() function, but then made multiple functions return a negative error code, and didn't actually check for the error in the caller. And it didn't actually work at all. BenH bisected down odd tty behavior to it: "It looks like the patch is causing some major malfunctions of the X server for me, possibly related to PTYs. For example, cat'ing a large file in a gnome terminal hangs the kernel for -minutes- in a loop of what looks like flush_to_ldisc/workqueue code, (some ftrace data in the quoted bits further down). ... Some more data: It -looks- like what happens is that the flush_to_ldisc work queue entry constantly re-queues itself (because the PTY is full ?) and the workqueue thread will basically loop forver calling it without ever scheduling, thus starving the consumer process that could have emptied the PTY." which is pretty much exactly the problem we fixed in a5660b41af6a. Milton Miller pointed out the 'unsigned int' issue.

* | mfd: Use mfd cell platform_data for twl4030 codec cells platform bitsSamuel Ortiz2011-05-261-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | With the addition of a platform device mfd_cell pointer, MFD drivers can go back to passing platform data back to their sub drivers. This allows for an mfd_cell->mfd_data removal and thus keep the sub drivers MFD agnostic. This is mostly needed for non MFD aware sub drivers.

Most of these files are new, generally adding a foo_64.c file where previously there was just a foo_32.c file. The ARCH=tilegx directive redirects to arch/tile, not arch/tilegx, using the existing SRCARCH mechanism in the top-level Makefile. Changes to existing files: - <asm/bitops.h> and <asm/bitops_32.h> changed to factor the include of <asm-generic/bitops/non-atomic.h> in the common header. - <asm/compat.h> and arch/tile/kernel/compat.c changed to remove the "const" markers I had put on compat_sys_execve() when trying to match some recent similar changes to the non-compat execve. It turns out the compat version wasn't "upgraded" to use const. - <asm/opcode-tile_64.h> and <asm/opcode_constants_64.h> were previously included accidentally, with the 32-bit contents. Now they have the proper 64-bit contents. Finally, I had to hack the existing hacky drivers/input/input-compat.h to add yet another "#ifdef" for INPUT_COMPAT_TEST (same as x86_64).

Looking at oscilloscope snapshots, this seems to be caused by the touch event disappearing during the measurements. These bogus values result in misclicks, where the X and Y values deviate from the real position. Most of these misclicks can be filtered out by setting a low enough threshold for the maximum resistance (which is loosely the inverse of the pressure) allowed to consider a set of values valid. Since this behaviour is largely dependent on the type and quality of the panel, this commit introduces the max_rt parameter. The default value is kept at MAX_12BIT.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apparently somewhere someone had a proprietary X driver. To get the multitouch info, it uses some hack on the normal API instead of using the multitouch protocol. Now that the multitouch info is transmitted correctly it makes not much sense to keep it.

Let's report the multitouch info also following the official MT protocol. It's semi-mt because the device only reports the lowest/highest coordinates. This was done following the multi-touch-protocol.txt documentation, and inspired by the bcm5974 and elantech implementations. Testing was light as there is not many applications using this protocol yet, but the X synaptics driver didn't complain and the X multitouch driver behaved correctly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch modifies evdev so that it only becomes readable when the buffer contains an EV_SYN/SYN_REPORT event. On SMP systems, it is possible for an evdev client blocked on poll() to wake up and read events from the evdev ring buffer at the same rate as they are enqueued. This can result in high CPU usage, particularly for MT devices, because the client ends up reading events one at a time instead of reading complete packets. We eliminate this problem by making the device readable only when the buffer contains at least one complete packet. This causes clients to block until the entire packet is available.
