From 9498f954a4ec389806333041a1018909c6fe0518 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Fri, 18 Mar 2011 14:27:52 +0100 Subject: HID: hid-multitouch: Auto detection of maxcontacts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch enables support of autodetection of maxcontacts. When adding support for a new device, one is now able to let the device tell how many contacts it supports, or to manually set the value if the device happens to provide wrong information.

It differs from hiddev in that reports sent and +received are not parsed by the HID parser, but are sent to and received from +the device unmodified. + +Hidraw should be used if the userspace application knows exactly how to +communicate with the hardware device, and is able to construct the HID +reports manually. This is often the case when making userspace drivers for +custom HID devices. + +Hidraw is also useful for communicating with non-conformant HID devices +which send and receive data in a way that is inconsistent with their report +descriptors. Because hiddev parses reports which are sent and received +through it, checking them against the device's report descriptor, such +communication with these non-conformant devices is impossible using hiddev. +Hidraw is the only alternative, short of writing a custom kernel driver, for +these non-conformant devices. + +A benefit of hidraw is that its use by userspace applications is independent +of the underlying hardware type. Currently, Hidraw is implemented for USB +and Bluetooth. In the future, as new hardware bus types are developed which +use the HID specification, hidraw will be expanded to add support for these +new bus types. + +Hidraw uses a dynamic major number, meaning that udev should be relied on to +create hidraw device nodes. Udev will typically create the device nodes +directly under /dev (eg: /dev/hidraw0). As this location is distribution- +and udev rule-dependent, applications should use libudev to locate hidraw +devices attached to the system. There is a tutorial on libudev with a +working example at: + http://www.signal11.us/oss/udev/ + +The HIDRAW API +--------------- + +read() +------- +read() will read a queued report received from the HID device. On USB +devices, the reports read using read() are the reports sent from the device +on the INTERRUPT IN endpoint. By default, read() will block until there is +a report available to be read. read() can be made non-blocking, by passing +the O_NONBLOCK flag to open(), or by setting the O_NONBLOCK flag using +fcntl(). + +On a device which uses numbered reports, the first byte of the returned data +will be the report number; the report data follows, beginning in the second +byte. For devices which do not use numbered reports, the report data +will begin at the first byte. + +write() +-------- +The write() function will write a report to the device. For USB devices, if +the device has an INTERRUPT OUT endpoint, the report will be sent on that +endpoint. If it does not, the report will be sent over the control endpoint, +using a SET_REPORT transfer. + +The first byte of the buffer passed to write() should be set to the report +number. If the device does not use numbered reports, the first byte should +be set to 0. The report data itself should begin at the second byte. + +ioctl() +-------- +Hidraw supports the following ioctls: + +HIDIOCGRDESCSIZE: Get Report Descriptor Size +This ioctl will get the size of the device's report descriptor. + +HIDIOCGRDESC: Get Report Descriptor +This ioctl returns the device's report descriptor using a +hidraw_report_descriptor struct. Make sure to set the size field of the +hidraw_report_descriptor struct to the size returned from HIDIOCGRDESCSIZE. + +HIDIOCGRAWINFO: Get Raw Info +This ioctl will return a hidraw_devinfo struct containing the bus type, the +vendor ID (VID), and product ID (PID) of the device. The bus type can be one +of: + BUS_USB + BUS_HIL + BUS_BLUETOOTH + BUS_VIRTUAL +which are defined in linux/input.h. + +HIDIOCGRAWNAME(len): Get Raw Name +This ioctl returns a string containing the vendor and product strings of +the device. The returned string is Unicode, UTF-8 encoded. + +HIDIOCGRAWPHYS(len): Get Physical Address +This ioctl returns a string representing the physical address of the device. +For USB devices, the string contains the physical path to the device (the +USB controller, hubs, ports, etc). For Bluetooth devices, the string +contains the hardware (MAC) address of the device. + +HIDIOCSFEATURE(len): Send a Feature Report +This ioctl will send a feature report to the device. Per the HID +specification, feature reports are always sent using the control endpoint. +Set the first byte of the supplied buffer to the report number. For devices +which do not use numbered reports, set the first byte to 0. The report data +begins in the second byte. Make sure to set len accordingly, to one more +than the length of the report (to account for the report number). + +HIDIOCGFEATURE(len): Get a Feature Report +This ioctl will request a feature report from the device using the control +endpoint. The first byte of the supplied buffer should be set to the report +number of the requested report. For devices which do not use numbered +reports, set the first byte to 0. The report will be returned starting at +the first byte of the buffer (ie: the report number is not returned). + +Example +--------- +In samples/, find hid-example.c, which shows examples of read(), write(), +and all the ioctls for hidraw.

If you need to write one, read on. + + +THE HIDDEV API +This description should be read in conjunction with the HID +specification, freely available from http://www.usb.org, and +conveniently linked of http://www.linux-usb.org. + +The hiddev API uses a read() interface, and a set of ioctl() calls. + +HID devices exchange data with the host computer using data +bundles called "reports". Each report is divided into "fields", +each of which can have one or more "usages". In the hid-core, +each one of these usages has a single signed 32 bit value. + +read(): +This is the event interface. When the HID device's state changes, +it performs an interrupt transfer containing a report which contains +the changed value. The hid-core.c module parses the report, and +returns to hiddev.c the individual usages that have changed within +the report. In its basic mode, the hiddev will make these individual +usage changes available to the reader using a struct hiddev_event: + + struct hiddev_event { + unsigned hid; + signed int value; + }; + +containing the HID usage identifier for the status that changed, and +the value that it was changed to. Note that the structure is defined +within , along with some other useful #defines and +structures. The HID usage identifier is a composite of the HID usage +page shifted to the 16 high order bits ORed with the usage code. The +behavior of the read() function can be modified using the HIDIOCSFLAG +ioctl() described below. + + +ioctl(): +This is the control interface. There are a number of controls: + +HIDIOCGVERSION - int (read) +Gets the version code out of the hiddev driver. + +HIDIOCAPPLICATION - (none) +This ioctl call returns the HID application usage associated with the +hid device. The third argument to ioctl() specifies which application +index to get. This is useful when the device has more than one +application collection. If the index is invalid (greater or equal to +the number of application collections this device has) the ioctl +returns -1. You can find out beforehand how many application +collections the device has from the num_applications field from the +hiddev_devinfo structure. + +HIDIOCGCOLLECTIONINFO - struct hiddev_collection_info (read/write) +This returns a superset of the information above, providing not only +application collections, but all the collections the device has. It +also returns the level the collection lives in the hierarchy. +The user passes in a hiddev_collection_info struct with the index +field set to the index that should be returned. The ioctl fills in +the other fields. If the index is larger than the last collection +index, the ioctl returns -1 and sets errno to -EINVAL. + +HIDIOCGDEVINFO - struct hiddev_devinfo (read) +Gets a hiddev_devinfo structure which describes the device. + +HIDIOCGSTRING - struct hiddev_string_descriptor (read/write) +Gets a string descriptor from the device. The caller must fill in the +"index" field to indicate which descriptor should be returned. + +HIDIOCINITREPORT - (none) +Instructs the kernel to retrieve all input and feature report values +from the device. At this point, all the usage structures will contain +current values for the device, and will maintain it as the device +changes. Note that the use of this ioctl is unnecessary in general, +since later kernels automatically initialize the reports from the +device at attach time. + +HIDIOCGNAME - string (variable length) +Gets the device name + +HIDIOCGREPORT - struct hiddev_report_info (write) +Instructs the kernel to get a feature or input report from the device, +in order to selectively update the usage structures (in contrast to +INITREPORT). + +HIDIOCSREPORT - struct hiddev_report_info (write) +Instructs the kernel to send a report to the device. This report can +be filled in by the user through HIDIOCSUSAGE calls (below) to fill in +individual usage values in the report before sending the report in full +to the device. + +HIDIOCGREPORTINFO - struct hiddev_report_info (read/write) +Fills in a hiddev_report_info structure for the user. The report is +looked up by type (input, output or feature) and id, so these fields +must be filled in by the user. The ID can be absolute -- the actual +report id as reported by the device -- or relative -- +HID_REPORT_ID_FIRST for the first report, and (HID_REPORT_ID_NEXT | +report_id) for the next report after report_id. Without a-priori +information about report ids, the right way to use this ioctl is to +use the relative IDs above to enumerate the valid IDs. The ioctl +returns non-zero when there is no more next ID. The real report ID is +filled into the returned hiddev_report_info structure. + +HIDIOCGFIELDINFO - struct hiddev_field_info (read/write) +Returns the field information associated with a report in a +hiddev_field_info structure. The user must fill in report_id and +report_type in this structure, as above. The field_index should also +be filled in, which should be a number from 0 and maxfield-1, as +returned from a previous HIDIOCGREPORTINFO call. + +HIDIOCGUCODE - struct hiddev_usage_ref (read/write) +Returns the usage_code in a hiddev_usage_ref structure, given that +given its report type, report id, field index, and index within the +field have already been filled into the structure. + +HIDIOCGUSAGE - struct hiddev_usage_ref (read/write) +Returns the value of a usage in a hiddev_usage_ref structure. The +usage to be retrieved can be specified as above, or the user can +choose to fill in the report_type field and specify the report_id as +HID_REPORT_ID_UNKNOWN. In this case, the hiddev_usage_ref will be +filled in with the report and field information associated with this +usage if it is found. + +HIDIOCSUSAGE - struct hiddev_usage_ref (write) +Sets the value of a usage in an output report. The user fills in +the hiddev_usage_ref structure as above, but additionally fills in +the value field. + +HIDIOGCOLLECTIONINDEX - struct hiddev_usage_ref (write) +Returns the collection index associated with this usage. This +indicates where in the collection hierarchy this usage sits. + +HIDIOCGFLAG - int (read) +HIDIOCSFLAG - int (write) +These operations respectively inspect and replace the mode flags +that influence the read() call above. The flags are as follows: + + HIDDEV_FLAG_UREF - read() calls will now return + struct hiddev_usage_ref instead of struct hiddev_event. + This is a larger structure, but in situations where the + device has more than one usage in its reports with the + same usage code, this mode serves to resolve such + ambiguity. + + HIDDEV_FLAG_REPORT - This flag can only be used in conjunction + with HIDDEV_FLAG_UREF.

Each report is divided into "fields", -each of which can have one or more "usages". In the hid-core, -each one of these usages has a single signed 32 bit value. - -read(): -This is the event interface. When the HID device's state changes, -it performs an interrupt transfer containing a report which contains -the changed value. The hid-core.c module parses the report, and -returns to hiddev.c the individual usages that have changed within -the report. In its basic mode, the hiddev will make these individual -usage changes available to the reader using a struct hiddev_event: - - struct hiddev_event { - unsigned hid; - signed int value; - }; - -containing the HID usage identifier for the status that changed, and -the value that it was changed to. Note that the structure is defined -within , along with some other useful #defines and -structures. The HID usage identifier is a composite of the HID usage -page shifted to the 16 high order bits ORed with the usage code. The -behavior of the read() function can be modified using the HIDIOCSFLAG -ioctl() described below. - - -ioctl(): -This is the control interface. There are a number of controls: - -HIDIOCGVERSION - int (read) -Gets the version code out of the hiddev driver. - -HIDIOCAPPLICATION - (none) -This ioctl call returns the HID application usage associated with the -hid device. The third argument to ioctl() specifies which application -index to get. This is useful when the device has more than one -application collection. If the index is invalid (greater or equal to -the number of application collections this device has) the ioctl -returns -1. You can find out beforehand how many application -collections the device has from the num_applications field from the -hiddev_devinfo structure. - -HIDIOCGCOLLECTIONINFO - struct hiddev_collection_info (read/write) -This returns a superset of the information above, providing not only -application collections, but all the collections the device has. It -also returns the level the collection lives in the hierarchy. -The user passes in a hiddev_collection_info struct with the index -field set to the index that should be returned. The ioctl fills in -the other fields. If the index is larger than the last collection -index, the ioctl returns -1 and sets errno to -EINVAL. - -HIDIOCGDEVINFO - struct hiddev_devinfo (read) -Gets a hiddev_devinfo structure which describes the device. - -HIDIOCGSTRING - struct hiddev_string_descriptor (read/write) -Gets a string descriptor from the device. The caller must fill in the -"index" field to indicate which descriptor should be returned. - -HIDIOCINITREPORT - (none) -Instructs the kernel to retrieve all input and feature report values -from the device. At this point, all the usage structures will contain -current values for the device, and will maintain it as the device -changes. Note that the use of this ioctl is unnecessary in general, -since later kernels automatically initialize the reports from the -device at attach time. - -HIDIOCGNAME - string (variable length) -Gets the device name - -HIDIOCGREPORT - struct hiddev_report_info (write) -Instructs the kernel to get a feature or input report from the device, -in order to selectively update the usage structures (in contrast to -INITREPORT). - -HIDIOCSREPORT - struct hiddev_report_info (write) -Instructs the kernel to send a report to the device. This report can -be filled in by the user through HIDIOCSUSAGE calls (below) to fill in -individual usage values in the report before sending the report in full -to the device. - -HIDIOCGREPORTINFO - struct hiddev_report_info (read/write) -Fills in a hiddev_report_info structure for the user. The report is -looked up by type (input, output or feature) and id, so these fields -must be filled in by the user. The ID can be absolute -- the actual -report id as reported by the device -- or relative -- -HID_REPORT_ID_FIRST for the first report, and (HID_REPORT_ID_NEXT | -report_id) for the next report after report_id. Without a-priori -information about report ids, the right way to use this ioctl is to -use the relative IDs above to enumerate the valid IDs. The ioctl -returns non-zero when there is no more next ID. The real report ID is -filled into the returned hiddev_report_info structure. - -HIDIOCGFIELDINFO - struct hiddev_field_info (read/write) -Returns the field information associated with a report in a -hiddev_field_info structure. The user must fill in report_id and -report_type in this structure, as above. The field_index should also -be filled in, which should be a number from 0 and maxfield-1, as -returned from a previous HIDIOCGREPORTINFO call. - -HIDIOCGUCODE - struct hiddev_usage_ref (read/write) -Returns the usage_code in a hiddev_usage_ref structure, given that -given its report type, report id, field index, and index within the -field have already been filled into the structure. - -HIDIOCGUSAGE - struct hiddev_usage_ref (read/write) -Returns the value of a usage in a hiddev_usage_ref structure. The -usage to be retrieved can be specified as above, or the user can -choose to fill in the report_type field and specify the report_id as -HID_REPORT_ID_UNKNOWN. In this case, the hiddev_usage_ref will be -filled in with the report and field information associated with this -usage if it is found. - -HIDIOCSUSAGE - struct hiddev_usage_ref (write) -Sets the value of a usage in an output report. The user fills in -the hiddev_usage_ref structure as above, but additionally fills in -the value field. - -HIDIOGCOLLECTIONINDEX - struct hiddev_usage_ref (write) -Returns the collection index associated with this usage. This -indicates where in the collection hierarchy this usage sits. - -HIDIOCGFLAG - int (read) -HIDIOCSFLAG - int (write) -These operations respectively inspect and replace the mode flags -that influence the read() call above. The flags are as follows: - - HIDDEV_FLAG_UREF - read() calls will now return - struct hiddev_usage_ref instead of struct hiddev_event. - This is a larger structure, but in situations where the - device has more than one usage in its reports with the - same usage code, this mode serves to resolve such - ambiguity. - - HIDDEV_FLAG_REPORT - This flag can only be used in conjunction - with HIDDEV_FLAG_UREF. With this flag set, when the device - sends a report, a struct hiddev_usage_ref will be returned - to read() filled in with the report_type and report_id, but - with field_index set to FIELD_INDEX_NONE.

To keep devices working the same way they used to with hid-3m-pct, we need to add two signal/noise ratios for width and height. We also need to work on width/height to send proper ABS_MT_ORIENTATION flag. Importing 3M into hid-multitouch also solved the bug in which devices handling width and height in their report descriptors did not show ABS_MT_TOUCH_MAJOR and ABS_MT_TOUCH_MINOR.

However, devices reporting in serial mode (DWAV and PenMount) do not send this field. Other devices (3M) add other fields in the reports descriptor that are not multitouch related at the end, thus the need to add a special case in the default case when handling events. A first work around has been set up but with PenMount devices, we have reached the limit. The idea is to calculate the last_field_index by relying only on multitouch fields the device send. This allows us to remove the handling of non-multitouch events in hid-multitouch, and guarantee that the function mt_emit_event is always called.

I'd initially written additions to hid-input.c with just this device in mind, including some bits that were specific to the device. This go around, I'm looking at adding/correcting as many generic HID usages from the HID Usage Tables, version 1.12, as I can -- which also serves to enable all but four of the buttons on the Tivo Slide remote[*]. Outside of fixing the obviously incorrect mapping of 0xc 0x45 from KEY_RADIO to KEY_RIGHT, and making use of the new KEY_IMAGES (just added in 2.6.39-rc4) for AL Image Browser instead of KEY_MEDIA, these are purely additions, and thus should have no negative impact on any already functional HID devices. Most of the added mappings seemed to be perfectly logical to me, but there were a few that were mapped on more of an "I think this makes the most sense" basis.
