2012-09-19HID: hid-multitouch: Simplify setup and frame synchronizationHenrik Rydberg
With the input_configured() callback in place, the setup and frame synchronization can be simplified. The input device initialization is moved to mt_input_configured(), to make sure the full HID report has been seen.

2012-09-19HID: Allow more fields in the hid reportHenrik Rydberg

2012-09-19HID: Add an input configured notification callbackHenrik Rydberg
A hid device may create several input devices, and a driver may need to prepare or finalize the configuration per input device. Currently, there is no sane way for a driver to know when a device has been configured. This patch adds a callback providing that information.

2012-09-19Input: MT - Add in-kernel trackingHenrik Rydberg
With the INPUT_MT_TRACK flag set, the function input_mt_assign_slots() can be used to match a new set of contacts against the currently used slots. The algorithm used is based on Lagrange relaxation, and performs very well in practice; slower than mtdev for a few corner cases, but faster in most commonly occuring cases.

2012-09-19Input: MT - Handle frame synchronization in coreHenrik Rydberg
Most MT drivers perform the same actions on frame synchronization. Some actions, like dropping unseen contacts, are also unnecessarily complex. Collect common frame synchronization tasks in a new function, input_mt_sync_frame(). Depending on the flags set, it drops unseen contacts and performs pointer emulation. With init flags and frame synchronization in place, most MT drivers can be simplified. First out are the bcm5974 and hid-multitouch drivers, following this patch.

2012-09-19Input: Send events one packet at a timeHenrik Rydberg
On heavy event loads, such as a multitouch driver, the irqsoff latency can be as high as 250 us. By accumulating a frame worth of data before passing it on, the latency can be dramatically reduced. As a side effect, the special EV_SYN handling can be removed, since the frame is now atomic. This patch adds the events() handler callback and uses it if it exists. The latency is improved by 50 us even without the callback.

2012-09-19Input: Improve the events-per-packet estimateHenrik Rydberg
The events-per-packet estimate has so far been used by MT devices only. This patch adjusts the packet buffer size to also accomodate the KEY and MSC events. Keyboards normally send one or two keys at a time. MT devices normally send a number of button keys along with the MT information. The buffer size chosen here covers those cases, and matches the default buffer size in evdev. Since the input estimate is now preferred, remove the special input-mt estimate.

2012-09-19Revert "input: ab8500-ponkey: Create AB8500 domain IRQ mapping"Dmitry Torokhov
This reverts commit ca3b3faf9bee4dc5df4f10eae2d1e48f7de0a8ad. There was a plan to place ab8500_irq_get_virq() calls in each AB8500 child device prior to requesting an IRQ, but as we're no longer using Device Tree to collect our IRQ numbers, it's actually better to allow the core to do this during device registration time. So the IRQ number we pull from its resource has already been converted to a virtual IRQ.

2012-09-19cpufreq/powernow-k8: workqueue user shouldn't migrate the kworker to another CPUTejun Heo
powernowk8_target() runs off a per-cpu work item and if the cpufreq_policy->cpu is different from the current one, it migrates the kworker to the target CPU by manipulating current->cpus_allowed. The function migrates the kworker back to the original CPU but this is still broken. Workqueue concurrency management requires the kworkers to stay on the same CPU and powernowk8_target() ends up triggerring BUG_ON(rq != this_rq()) in try_to_wake_up_local() if it contends on fidvid_mutex and sleeps. It is unclear why this bug is being reported now. Duncan says it appeared to be a regression of 3.6-rc1 and couldn't reproduce it on 3.5. Bisection seemed to point to 63d95a91 "workqueue: use @pool instead of @gcwq or @cpu where applicable" which is an non-functional change. Given that the reproduce case sometimes took upto days to trigger, it's easy to be misled while bisecting. Maybe something made contention on fidvid_mutex more likely? I don't know. This patch fixes the bug by using work_on_cpu() instead if @pol->cpu isn't the same as the current one. The code assumes that cpufreq_policy->cpu is kept online by the caller, which Rafael tells me is the case. stable: ed48ece27c ("workqueue: reimplement work_on_cpu() using system_wq") should be applied before this; otherwise, the behavior could be horrible.

2012-09-19workqueue: reimplement work_on_cpu() using system_wqTejun Heo
The existing work_on_cpu() implementation is hugely inefficient. It creates a new kthread, execute that single function and then let the kthread die on each invocation. Now that system_wq can handle concurrent executions, there's no advantage of doing this. Reimplement work_on_cpu() using system_wq which makes it simpler and way more efficient. stable: While this isn't a fix in itself, it's needed to fix a workqueue related bug in cpufreq/powernow-k8. AFAICS, this shouldn't break other existing users.

2012-09-19linux/kernel.h: Fix warning seen with W=1 due to change in DIV_ROUND_CLOSESTGuenter Roeck
After commit b6d86d3d (Fix DIV_ROUND_CLOSEST to support negative dividends), the following warning is seen if the kernel is compiled with W=1 (-Wextra): warning: comparison of unsigned expression >= 0 is always true The warning is due to the test '((typeof(x))-1) >= 0', which is used to detect if the variable type is unsigned. Research on the web suggests that the warning disappears if '>' instead of '>=' is used for the comparison. Tests after changing the macro along that line show that the warning is gone, and that the result is still correct: i=-4: DIV_ROUND_CLOSEST(i, 2)=-2 i=-3: DIV_ROUND_CLOSEST(i, 2)=-2 i=-2: DIV_ROUND_CLOSEST(i, 2)=-1 i=-1: DIV_ROUND_CLOSEST(i, 2)=-1 i=0: DIV_ROUND_CLOSEST(i, 2)=0 i=1: DIV_ROUND_CLOSEST(i, 2)=1 i=2: DIV_ROUND_CLOSEST(i, 2)=1 i=3: DIV_ROUND_CLOSEST(i, 2)=2 i=4: DIV_ROUND_CLOSEST(i, 2)=2 Code size is the same as before.

2012-09-19staging: comedi: sparse warning in insn_rw_emulate_bits()Ian Abbott
`insn_rw_emulate_bits()` is used to emulate the `INSN_READ` and `INSN_WRITE` comedi instructions for subdevices that don't have an `insn_read()` or `insn_write()` handler but do have an `insn_bits()` handler. The function fills in a temporary `struct comedi_insn` called `new_insn` to pass to the subdevice's `insn_bits()` handler. In doing so, it sets the `new_insn.data` pointer to point to a temporary data array. This results in a warning from "sparse" because the `data` pointer in `struct comedi_insn` has the `__user` tag. The subdevice's `insn_bits()` handler ignores it anyway as it gets passed a pointer to the temporary data array in a separate parameter. Don't bother setting `new_insn.data`; just leave it set to `NULL` (done by an earlier `memset()`).

2012-09-19staging: comedi: fix sparse warning in do_devconfig_ioctl()Ian Abbott
For the COMEDI_DEVCONFIG ioctl, the user application may embed a pointer to firmware data within a designated element (or two elements for 64-bit pointers) of the `options[]` array in the `struct comedi_devconfig`. `do_devconfig_ioctl()` calls `comedi_aux_data()` to extract the pointer value. It needs to be treated as a `__user` pointer so the firmware data can be copied into kernel memory, so cast the result of `comedi_aux_data()` to avoid a "sparse" warning. This is not ideal but `comedi_aux_data()` is called elsewhere in a wholly kernel memory context so we can't just change its return type to include the `__user` tag.

2012-09-19staging: comedi: daqboard2000: use attach_pci callbackH Hartley Sweeten
Convert this PCI driver to use the comedi PCI auto config attach mechanism by adding an 'attach_pci' callback function. Since the driver does not require any external configuration options. and the legacy 'attach' callback is now optional, remove it.

2012-09-19staging: comedi: daqboard2000: use request_firmware()H Hartley Sweeten
This driver requires loading a firmware file for the cpld. This is currently being done by passing the firmware data using the COMEDI_DEVCONFIG ioctl through the attach() hook in the driver. This does not work for auto-configured PCI devices due to the firmware loading options not being set in the comedi_devconfig parameter passed to the driver. Change the driver so it gets the firmware using request_firmware() and ignore any firmware options passed in the comedi_devconfig.
