* Input: synaptics - ignore bogus mt packetHenrik Rydberg2010-12-22
| | | | | | | | | | | | | In multitouch mode, at least one device (fw: 7.4 id: 0x1c0b1) sometimes sends a final main packet with x == 1. Since the normal values are above 1472, this is clearly bogus. At the same time, a two-finger touch is signaled, even though only one finger was on the pad to begin with. This patch ignores the packet altogether, removing the problem.

* Input: synaptics - add multi-finger and semi-mt supportHenrik Rydberg2010-12-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Synaptics 2.7 series of touchpads support a mode for reporting two sets of X/Y/Pressure data (advanced gesture mode). By default, these devices report only single finger data, depriving userspace of the nowadays ubiquitous two-finger scroll gesture. Enabling advanced gesture mode also enables the multi-finger report, although the device does not claim that capability. Up to three fingers can be reported this way. While two or three fingers are touching, the normal packet is prepended by a reduced finger packet of lower resolution. From the two packets (which do not represent the actual fingers), the bounding rectangle of the individual contacts can be extracted. This information is sufficient to perform scaling gestures and a limited form of rotation gesture. The behavior has been coined semi-mt capability, and is signaled to userspace via the INPUT_PROP_SEMI_MT device property. Work to decode the advanced gesture packet: Takashi Iwai. Cleanup and testing of the original patch: Chase Douglas. Minor cleanup and testing: Chris Bagwell. Finalization and semi-mt support: Henrik Rydberg.

* Input: synaptics - report clickpad propertyHenrik Rydberg2010-12-21
| | | | | | | | | | With the new input property interface, it is possible to report the special quirks of a device using ioctl/sysfs. This patch sets up the device as a pointer, and reports the clickpad functionality via the INPUT_PROP_BUTTONPAD property.

* Input: fix double equality sign in ueventHenrik Rydberg2010-12-20
| | | | | | | | | | | Looking at the uevent stream for input devices, all properties are on the form "A=B" except the bitmap values, which are on the form "A==B". This bug has been around at least since 2007, and the input uevent code has been untouched since. The recent addition of device properties suggests this is a good time for a remedy.

* Input: introduce device propertiesHenrik Rydberg2010-12-20
| | | | | | | | | | | | | | | | | | Today, userspace sets up an input device based on the data it emits. This is not always enough; a tablet and a touchscreen may emit exactly the same data, for instance, but the former should be set up with a pointer whereas the latter does not need to. Recently, a new type of touchpad has emerged where the buttons are under the pad, which changes logic without changing the emitted data. This patch introduces a new ioctl, EVIOCGPROP, which enables user access to a set of device properties useful during setup. The properties are given as a bitmap in the same fashion as the event types, and are also made available via sysfs, uevent and /proc/bus/input/devices.

* hid: egalax: Convert to MT slotsHenrik Rydberg2010-12-16
| | | | | | | | | | | | | The firmware in the joojoo reports touches sequentially, one per report, which confuses the current driver. A further complication is the absense of any indication of a touch frame. This patch converts the driver to the MT slots protocol, and outputs one full touch frame per report. This way, proper handling for both firmwares is ensured.

* input: mt: Move tracking and pointer emulation to input-mtHenrik Rydberg2010-12-16
| | | | | | | | | | | | | | | 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.

The convention is intended to reduce text usage by sharing the common bits of the string, but the implementation is inherently fragile (a change to one format string but not the other will nullify any possible advantage), it isn't necessarily a net win depending on what this compiler does, and it it reduces code readability.

The AD7879 data available interrupt signals (DAV) completion, however some X,Y values are not valid because the screen inputs were floating during the acquisition. The AD7877 acts differently here, since it only asserts DAV if the touch is still present when the conversion sequence finished. Based on the fact that this can only happen in the last sample of the repeated conversion sequence, we simply skip the last (short glitches are filtered by the AD7879 internal median and average filters). This doesn't cause noticeable side effects, since the minimum conversion interval is 9.44ms. We receive ~100 waypoint samples per second, so we simply delay the result by 9.44ms. We also reject samples where pressure is greater than pressure_max. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

| * | | | | [SCSI] libosd: Support for scatter gather write/read commandsBoaz Harrosh2010-10-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the Scatter-Gather (sg) API to libosd. Scatter-gather enables a write/read of multiple none-contiguous areas of an object, in a single call. The extents may overlap and/or be in any order. The Scatter-Gather list is sent to the target in what is called a "cdb continuation segment". This is yet another possible segment in the osd-out-buffer. It is unlike all other segments in that it sits before the actual "data" segment (which until now was always first), and that it is signed by itself and not part of the data buffer. This is because the cdb-continuation-segment is considered a spill-over of the CDB data, and is therefor signed under OSD_SEC_CAPKEY and higher. TODO: A new osd_finalize_request_ex version should be supplied so the @caps received on the network also contains a size parameter and can be spilled over into the "cdb continuation segment". Thanks to John Chandy <john.chandy@uconn.edu> for the original code, and investigations. And the implementation of SG support in the osd-target.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At osd_end_request first free the request that might point to pages, then free these pages. In reverse order of allocation. For now it's just anal neatness. When we'll use mempools It'll also pay in performance.

| * | | | | [SCSI] libosd: Fix bug in attr_page handlingBoaz Harrosh2010-10-26

Also properly support when we don't have any attribute to set while getting a full page. And when clearing an attribute by setting it's size to zero.
