In this document we call them: + + 1. The "HID I/O Driver" is the driver that performs raw data I/O to the + low-level device. Internally, they register an hid_ll_driver structure with + the HID core. They perform device setup, read raw data from the device and + push it into the HID subsystem and they provide a callback so the HID + subsystem can send data to the device. + + 2. The "HID Device Driver" is the driver that parses HID reports and reacts on + them. There are generic drivers like "generic-usb" and "generic-bluetooth" + which adhere to the HID specification and provide the standardizes features. + But there may be special drivers and quirks for each non-standard device out + there. Internally, they use the hid_driver structure. + +Historically, the USB stack was the first subsystem to provide an HID I/O +Driver. However, other standards like Bluetooth have adopted the HID specs and +may provide HID I/O Drivers, too. The UHID driver allows to implement HID I/O +Drivers in user-space and feed the data into the kernel HID-subsystem. + +This allows user-space to operate on the same level as USB-HID, Bluetooth-HID +and similar. It does not provide a way to write HID Device Drivers, though. Use +hidraw for this purpose. + +There is an example user-space application in ./samples/uhid/uhid-example.c + +The UHID API +------------ + +UHID is accessed through a character misc-device. The minor-number is allocated +dynamically so you need to rely on udev (or similar) to create the device node. +This is /dev/uhid by default. + +If a new device is detected by your HID I/O Driver and you want to register this +device with the HID subsystem, then you need to open /dev/uhid once for each +device you want to register. All further communication is done by read()'ing or +write()'ing "struct uhid_event" objects. Non-blocking operations are supported +by setting O_NONBLOCK. + +struct uhid_event { + __u32 type; + union { + struct uhid_create_req create; + struct uhid_data_req data; + ... + } u; +}; + +The "type" field contains the ID of the event. Depending on the ID different +payloads are sent. You must not split a single event across multiple read()'s or +multiple write()'s. A single event must always be sent as a whole. Furthermore, +only a single event can be sent per read() or write(). Pending data is ignored. +If you want to handle multiple events in a single syscall, then use vectored +I/O with readv()/writev(). + +The first thing you should do is sending an UHID_CREATE event. This will +register the device. UHID will respond with an UHID_START event. You can now +start sending data to and reading data from UHID. However, unless UHID sends the +UHID_OPEN event, the internally attached HID Device Driver has no user attached. +That is, you might put your device asleep unless you receive the UHID_OPEN +event. If you receive the UHID_OPEN event, you should start I/O. If the last +user closes the HID device, you will receive an UHID_CLOSE event. This may be +followed by an UHID_OPEN event again and so on. There is no need to perform +reference-counting in user-space. That is, you will never receive multiple +UHID_OPEN events without an UHID_CLOSE event. The HID subsystem performs +ref-counting for you. +You may decide to ignore UHID_OPEN/UHID_CLOSE, though. I/O is allowed even +though the device may have no users. + +If you want to send data to the HID subsystem, you send an HID_INPUT event with +your raw data payload. If the kernel wants to send data to the device, you will +read an UHID_OUTPUT or UHID_OUTPUT_EV event. + +If your device disconnects, you should send an UHID_DESTROY event. This will +unregister the device. You can now send UHID_CREATE again to register a new +device. +If you close() the fd, the device is automatically unregistered and destroyed +internally. + +write() +------- +write() allows you to modify the state of the device and feed input data into +the kernel. The following types are supported: UHID_CREATE, UHID_DESTROY and +UHID_INPUT. The kernel will parse the event immediately and if the event ID is +not supported, it will return -EOPNOTSUPP. If the payload is invalid, then +-EINVAL is returned, otherwise, the amount of data that was read is returned and +the request was handled successfully. + + UHID_CREATE: + This creates the internal HID device. No I/O is possible until you send this + event to the kernel. The payload is of type struct uhid_create_req and + contains information about your device. You can start I/O now. + + UHID_DESTROY: + This destroys the internal HID device. No further I/O will be accepted. There + may still be pending messages that you can receive with read() but no further + UHID_INPUT events can be sent to the kernel. + You can create a new device by sending UHID_CREATE again. There is no need to + reopen the character device. + + UHID_INPUT: + You must send UHID_CREATE before sending input to the kernel! This event + contains a data-payload. This is the raw data that you read from your device. + The kernel will parse the HID reports and react on it. + + UHID_FEATURE_ANSWER: + If you receive a UHID_FEATURE request you must answer with this request. You + must copy the "id" field from the request into the answer. Set the "err" field + to 0 if no error occured or to EIO if an I/O error occurred. + If "err" is 0 then you should fill the buffer of the answer with the results + of the feature request and set "size" correspondingly. + +read() +------ +read() will return a queued ouput report. These output reports can be of type +UHID_START, UHID_STOP, UHID_OPEN, UHID_CLOSE, UHID_OUTPUT or UHID_OUTPUT_EV. No +reaction is required to any of them but you should handle them according to your +needs. Only UHID_OUTPUT and UHID_OUTPUT_EV have payloads. + + UHID_START: + This is sent when the HID device is started. Consider this as an answer to + UHID_CREATE. This is always the first event that is sent. + + UHID_STOP: + This is sent when the HID device is stopped. Consider this as an answer to + UHID_DESTROY. + If the kernel HID device driver closes the device manually (that is, you + didn't send UHID_DESTROY) then you should consider this device closed and send + an UHID_DESTROY event. You may want to reregister your device, though. This is + always the last message that is sent to you unless you reopen the device with + UHID_CREATE. + + UHID_OPEN: + This is sent when the HID device is opened. That is, the data that the HID + device provides is read by some other process. You may ignore this event but + it is useful for power-management. As long as you haven't received this event + there is actually no other process that reads your data so there is no need to + send UHID_INPUT events to the kernel. + + UHID_CLOSE: + This is sent when there are no more processes which read the HID data. It is + the counterpart of UHID_OPEN and you may as well ignore this event. + + UHID_OUTPUT: + This is sent if the HID device driver wants to send raw data to the I/O + device. You should read the payload and forward it to the device. The payload + is of type "struct uhid_data_req". + This may be received even though you haven't received UHID_OPEN, yet. + + UHID_OUTPUT_EV: + Same as UHID_OUTPUT but this contains a "struct input_event" as payload. This + is called for force-feedback, LED or similar events which are received through + an input device by the HID subsystem. You should convert this into raw reports + and send them to your device similar to events of type UHID_OUTPUT. + + UHID_FEATURE: + This event is sent if the kernel driver wants to perform a feature request as + described in the HID specs. The report-type and report-number are available in + the payload. + The kernel serializes feature requests so there will never be two in parallel. + However, if you fail to respond with a UHID_FEATURE_ANSWER in a time-span of 5 + seconds, then the requests will be dropped and a new one might be sent. + Therefore, the payload also contains an "id" field that identifies every + request. + +Document by: + David Herrmann diff --git a/Documentation/hwmon/da9052 b/Documentation/hwmon/da9052 new file mode 100644 index 0000000000000000000000000000000000000000..ef898553638ef960840202892a0060343c57981a --- /dev/null +++ b/Documentation/hwmon/da9052 @@ -0,0 +1,61 @@ +Supported chips: + * Dialog Semiconductors DA9052-BC and DA9053-AA/Bx PMICs + Prefix: 'da9052' + Datasheet: Datasheet is not publicly available. + +Authors: David Dajun Chen + +Description +----------- + +The DA9052/53 provides an Analogue to Digital Converter (ADC) with 10 bits +resolution and track and hold circuitry combined with an analogue input +multiplexer.

It + will talk only briefly about how to use MSF within composite + gadgets. + +* Module parameters + + The mass storage gadget accepts the following mass storage specific + module parameters: + + - file=filename[,filename...] + + This parameter lists paths to files or block devices used for + backing storage for each logical unit. There may be at most + FSG_MAX_LUNS (8) LUNs set. If more files are specified, they will + be silently ignored.

The logical block size is 2048 bytes for LUNs + simulating CD-ROM, block size of the device if the backing file is + a block device, or 512 bytes otherwise. + + - removable=b[,b...] + + This parameter specifies whether each logical unit should be + removable. “b” here is either “y”, “Y” or “1” for true or “n”, + “N” or “0” for false. + + If this option is set for a logical unit, gadget will accept an + “eject” SCSI request (Start/Stop Unit). When it is sent, the + backing file will be closed to simulate ejection and the logical + unit will not be mountable by the host until a new backing file is + specified by userspace on the device (see “sysfs entries” + section). + + If a logical unit is not removable (the default), a backing file + must be specified for it with the “file” parameter as the module + is loaded.

Thus to + maintain compatibility with older kernels, it's best to specify + the default values. Also, if one relied on old default, explicit + “n” needs to be specified now. + + Note that “removable” means the logical unit's media can be + ejected or removed (as is true for a CD-ROM drive or a card + reader).

This will prevent host from modifying the + backing files. + + Note that if this flag for given logical unit is false but the + backing file could not be opened in read/write mode, the gadget + will fall back to read only mode anyway. + + The default value for non-CD-ROM logical units is false; for + logical units simulating CD-ROM it is forced to true. + + - nofua=b[,b...] + + This parameter specifies whether FUA flag should be ignored in SCSI + Write10 and Write12 commands sent to given logical units. + + MS Windows mounts removable storage in “Removal optimised mode” by + default. All the writes to the media are synchronous, which is + achieved by setting the FUA (Force Unit Access) bit in SCSI + Write(10,12) commands.

It is limited by FSG_MAX_LUNS (8) and higher value will be + capped. + + If this parameter is provided, and the number of files specified + in “file” argument is greater then the value of “luns”, all excess + files will be ignored. + + If this parameter is not present, the number of logical units will + be deduced from the number of files specified in the “file” + parameter. If the file parameter is missing as well, one is + assumed. + + - stall=b + + Specifies whether the gadget is allowed to halt bulk endpoints. + The default is determined according to the type of USB device + controller, but usually true. + + In addition to the above, the gadget also accepts the following + parameters defined by the composite framework (they are common to + all composite gadgets so just a quick listing): + + - idVendor -- USB Vendor ID (16 bit integer) + - idProduct -- USB Product ID (16 bit integer) + - bcdDevice -- USB Device version (BCD) (16 bit integer) + - iManufacturer -- USB Manufacturer string (string) + - iProduct -- USB Product string (string) + - iSerialNumber -- SerialNumber string (sting) + +* sysfs entries + + For each logical unit, the gadget creates a directory in the sysfs + hierarchy.

All users need to transition + to the Mass Storage Gadget by that time. The two gadgets behave + mostly the same from the outside except: + + 1.

FSG's “serial”, “vendor”, “product” and “release” module + parameters are handled in MSG by the composite layer's parameters + named respectively: “iSerialnumber”, “idVendor”, “idProduct” and + “bcdDevice”. + + 3. MSG does not support FSG's test mode, thus “transport”, + “protocol” and “buflen” FSG's module parameters are not + supported.

This includes x86 hardware with AMD-Vi and Intel VT-d, +POWER systems with Partitionable Endpoints (PEs) and embedded PowerPC +systems such as Freescale PAMU. The VFIO driver is an IOMMU/device +agnostic framework for exposing direct device access to userspace, in +a secure, IOMMU protected environment. In other words, this allows +safe[2], non-privileged, userspace drivers. + +Why do we want that? Virtual machines often make use of direct device +access ("device assignment") when configured for the highest possible +I/O performance. From a device and host perspective, this simply +turns the VM into a userspace driver, with the benefits of +significantly reduced latency, higher bandwidth, and direct use of +bare-metal device drivers[3]. + +Some applications, particularly in the high performance computing +field, also benefit from low-overhead, direct device access from +userspace. Examples include network adapters (often non-TCP/IP based) +and compute accelerators. Prior to VFIO, these drivers had to either +go through the full development cycle to become proper upstream +driver, be maintained out of tree, or make use of the UIO framework, +which has no notion of IOMMU protection, limited interrupt support, +and requires root privileges to access things like PCI configuration +space. + +The VFIO driver framework intends to unify these, replacing both the +KVM PCI specific device assignment code as well as provide a more +secure, more featureful userspace driver environment than UIO. + +Groups, Devices, and IOMMUs +------------------------------------------------------------------------------- + +Devices are the main target of any I/O driver. Devices typically +create a programming interface made up of I/O access, interrupts, +and DMA. Without going into the details of each of these, DMA is +by far the most critical aspect for maintaining a secure environment +as allowing a device read-write access to system memory imposes the +greatest risk to the overall system integrity. + +To help mitigate this risk, many modern IOMMUs now incorporate +isolation properties into what was, in many cases, an interface only +meant for translation (ie. solving the addressing problems of devices +with limited address spaces). With this, devices can now be isolated +from each other and from arbitrary memory access, thus allowing +things like secure direct assignment of devices into virtual machines. + +This isolation is not always at the granularity of a single device +though. Even when an IOMMU is capable of this, properties of devices, +interconnects, and IOMMU topologies can each reduce this isolation. +For instance, an individual device may be part of a larger multi- +function enclosure. While the IOMMU may be able to distinguish +between devices within the enclosure, the enclosure may not require +transactions between devices to reach the IOMMU. Examples of this +could be anything from a multi-function PCI device with backdoors +between functions to a non-PCI-ACS (Access Control Services) capable +bridge allowing redirection without reaching the IOMMU. Topology +can also play a factor in terms of hiding devices. A PCIe-to-PCI +bridge masks the devices behind it, making transaction appear as if +from the bridge itself. Obviously IOMMU design plays a major factor +as well. + +Therefore, while for the most part an IOMMU may have device level +granularity, any system is susceptible to reduced granularity. The +IOMMU API therefore supports a notion of IOMMU groups. A group is +a set of devices which is isolatable from all other devices in the +system. Groups are therefore the unit of ownership used by VFIO. + +While the group is the minimum granularity that must be used to +ensure secure user access, it's not necessarily the preferred +granularity. In IOMMUs which make use of page tables, it may be +possible to share a set of page tables between different groups, +reducing the overhead both to the platform (reduced TLB thrashing, +reduced duplicate page tables), and to the user (programming only +a single set of translations). For this reason, VFIO makes use of +a container class, which may hold one or more groups. A container +is created by simply opening the /dev/vfio/vfio character device. + +On its own, the container provides little functionality, with all +but a couple version and extension query interfaces locked away. +The user needs to add a group into the container for the next level +of functionality. To do this, the user first needs to identify the +group associated with the desired device. This can be done using +the sysfs links described in the example below. By unbinding the +device from the host driver and binding it to a VFIO driver, a new +VFIO group will appear for the group as /dev/vfio/$GROUP, where +$GROUP is the IOMMU group number of which the device is a member. +If the IOMMU group contains multiple devices, each will need to +be bound to a VFIO driver before operations on the VFIO group +are allowed (it's also sufficient to only unbind the device from +host drivers if a VFIO driver is unavailable; this will make the +group available, but not that particular device). TBD - interface +for disabling driver probing/locking a device. + +Once the group is ready, it may be added to the container by opening +the VFIO group character device (/dev/vfio/$GROUP) and using the +VFIO_GROUP_SET_CONTAINER ioctl, passing the file descriptor of the +previously opened container file. If desired and if the IOMMU driver +supports sharing the IOMMU context between groups, multiple groups may +be set to the same container.

When devices are bound and unbound to the driver, +the driver should call vfio_add_group_dev() and vfio_del_group_dev() +respectively: + +extern int vfio_add_group_dev(struct iommu_group *iommu_group, + struct device *dev, + const struct vfio_device_ops *ops, + void *device_data); + +extern void *vfio_del_group_dev(struct device *dev); + +vfio_add_group_dev() indicates to the core to begin tracking the +specified iommu_group and register the specified dev as owned by +a VFIO bus driver. The driver provides an ops structure for callbacks +similar to a file operations structure: + +struct vfio_device_ops { + int (*open)(void *device_data); + void (*release)(void *device_data); + ssize_t (*read)(void *device_data, char __user *buf, + size_t count, loff_t *ppos); + ssize_t (*write)(void *device_data, const char __user *buf, + size_t size, loff_t *ppos); + long (*ioctl)(void *device_data, unsigned int cmd, + unsigned long arg); + int (*mmap)(void *device_data, struct vm_area_struct *vma); +}; + +Each function is passed the device_data that was originally registered +in the vfio_add_group_dev() call above. This allows the bus driver +an easy place to store its opaque, private data. The open/release +callbacks are issued when a new file descriptor is created for a +device (via VFIO_GROUP_GET_DEVICE_FD). The ioctl interface provides +a direct pass through for VFIO_DEVICE_* ioctls. The read/write/mmap +interfaces implement the device region access defined by the device's +own VFIO_DEVICE_GET_REGION_INFO ioctl. + +------------------------------------------------------------------------------- + +[1] VFIO was originally an acronym for "Virtual Function I/O" in its +initial implementation by Tom Lyon while as Cisco. We've since +outgrown the acronym, but it's catchy. + +[2] "safe" also depends upon a device being "well behaved". It's +possible for multi-function devices to have backdoors between +functions and even for single function devices to have alternative +access to things like PCI config space through MMIO registers. To +guard against the former we can include additional precautions in the +IOMMU driver to group multi-function PCI devices together +(iommu=group_mf). The latter we can't prevent, but the IOMMU should +still provide isolation. For PCI, SR-IOV Virtual Functions are the +best indicator of "well behaved", as these are designed for +virtualization usage models. + +[3] As always there are trade-offs to virtual machine device +assignment that are beyond the scope of VFIO.
