Contents +----------- + +1. Intro +2. The interface +3. References +4. CREDITS + + +1. Intro +-------- + +ATA/ATAPI-7 specifies the IDLE IMMEDIATE command with unload feature. +Issuing this command should cause the drive to switch to idle mode and +unload disk heads. This feature is being used in modern laptops in +conjunction with accelerometers and appropriate software to implement +a shock protection facility. The idea is to stop all I/O operations on +the internal hard drive and park its heads on the ramp when critical +situations are anticipated. The desire to have such a feature +available on GNU/Linux systems has been the original motivation to +implement a generic disk head parking interface in the Linux kernel. +Please note, however, that other components have to be set up on your +system in order to get disk shock protection working (see +section 3. References below for pointers to more information about +that). + + +2. The interface +---------------- + +For each ATA device, the kernel exports the file +block/*/device/unload_heads in sysfs (here assumed to be mounted under +/sys). Access to /sys/block/*/device/unload_heads is denied with +-EOPNOTSUPP if the device does not support the unload feature. +Otherwise, writing an integer value to this file will take the heads +of the respective drive off the platter and block all I/O operations +for the specified number of milliseconds. When the timeout expires and +no further disk head park request has been issued in the meantime, +normal operation will be resumed. The maximal value accepted for a +timeout is 30000 milliseconds. Exceeding this limit will return +-EOVERFLOW, but heads will be parked anyway and the timeout will be +set to 30 seconds. However, you can always change a timeout to any +value between 0 and 30000 by issuing a subsequent head park request +before the timeout of the previous one has expired. In particular, the +total timeout can exceed 30 seconds and, more importantly, you can +cancel a previously set timeout and resume normal operation +immediately by specifying a timeout of 0. Values below -2 are rejected +with -EINVAL (see below for the special meaning of -1 and -2). If the +timeout specified for a recent head park request has not yet expired, +reading from /sys/block/*/device/unload_heads will report the number +of milliseconds remaining until normal operation will be resumed; +otherwise, reading the unload_heads attribute will return 0. + +For example, do the following in order to park the heads of drive +/dev/sda and stop all I/O operations for five seconds: + +# echo 5000 > /sys/block/sda/device/unload_heads + +A simple + +# cat /sys/block/sda/device/unload_heads + +will show you how many milliseconds are left before normal operation +will be resumed. + +A word of caution: The fact that the interface operates on a basis of +milliseconds may raise expectations that cannot be satisfied in +reality. In fact, the ATA specs clearly state that the time for an +unload operation to complete is vendor specific. The hint in ATA-7 +that this will typically be within 500 milliseconds apparently has +been dropped in ATA-8. + +There is a technical detail of this implementation that may cause some +confusion and should be discussed here. When a head park request has +been issued to a device successfully, all I/O operations on the +controller port this device is attached to will be deferred. That is +to say, any other device that may be connected to the same port will +be affected too. The only exception is that a subsequent head unload +request to that other device will be executed immediately. Further +operations on that port will be deferred until the timeout specified +for either device on the port has expired. As far as PATA (old style +IDE) configurations are concerned, there can only be two devices +attached to any single port. In SATA world we have port multipliers +which means that a user-issued head parking request to one device may +actually result in stopping I/O to a whole bunch of devices. However, +since this feature is supposed to be used on laptops and does not seem +to be very useful in any other environment, there will be mostly one +device per port. Even if the CD/DVD writer happens to be connected to +the same port as the hard drive, it generally *should* recover just +fine from the occasional buffer under-run incurred by a head park +request to the HD. Actually, when you are using an ide driver rather +than its libata counterpart (i.e. your disk is called /dev/hda +instead of /dev/sda), then parking the heads of one drive (drive X) +will generally not affect the mode of operation of another drive +(drive Y) on the same port as described above. It is only when a port +reset is required to recover from an exception on drive Y that further +I/O operations on that drive (and the reset itself) will be delayed +until drive X is no longer in the parked state. + +Finally, there are some hard drives that only comply with an earlier +version of the ATA standard than ATA-7, but do support the unload +feature nonetheless. Unfortunately, there is no safe way Linux can +detect these devices, so you won't be able to write to the +unload_heads attribute. If you know that your device really does +support the unload feature (for instance, because the vendor of your +laptop or the hard drive itself told you so), then you can tell the +kernel to enable the usage of this feature for that drive by writing +the special value -1 to the unload_heads attribute: + +# echo -1 > /sys/block/sda/device/unload_heads + +will enable the feature for /dev/sda, and giving -2 instead of -1 will +disable it again. + + +3. References +------------- + +There are several laptops from different vendors featuring shock +protection capabilities. As manufacturers have refused to support open +source development of the required software components so far, Linux +support for shock protection varies considerably between different +hardware implementations. Ideally, this section should contain a list +of pointers at different projects aiming at an implementation of shock +protection on different systems.

Typically a + specialised interface, present on many SoCs, e.g., PXA27x and PXA3xx, SuperH, + AVR32, i.MX27, i.MX31. + - camera host bus - a connection between a camera host and a camera. Can be + parallel or serial, consists of data and control lines, e.g., clock, vertical + and horizontal synchronization signals. + +Purpose of the soc-camera subsystem +----------------------------------- + +The soc-camera subsystem provides a unified API between camera host drivers and +camera sensor drivers. It implements a V4L2 interface to the user, currently +only the mmap method is supported. + +This subsystem has been written to connect drivers for System-on-Chip (SoC) +video capture interfaces with drivers for CMOS camera sensor chips to enable +the reuse of sensor drivers with various hosts. The subsystem has been designed +to support multiple camera host interfaces and multiple cameras per interface, +although most applications have only one camera sensor. + +Existing drivers +---------------- + +As of 2.6.27-rc4 there are two host drivers in the mainline: pxa_camera.c for +PXA27x SoCs and sh_mobile_ceu_camera.c for SuperH SoCs, and four sensor drivers: +mt9m001.c, mt9m111.c, mt9v022.c and a generic soc_camera_platform.c driver. This +list is not supposed to be updated, look for more examples in your tree. + +Camera host API +--------------- + +A host camera driver is registered using the + +soc_camera_host_register(struct soc_camera_host *); + +function. The host object can be initialized as follows: + +static struct soc_camera_host pxa_soc_camera_host = { + .drv_name = PXA_CAM_DRV_NAME, + .ops = &pxa_soc_camera_host_ops, +}; + +All camera host methods are passed in a struct soc_camera_host_ops: + +static struct soc_camera_host_ops pxa_soc_camera_host_ops = { + .owner = THIS_MODULE, + .add = pxa_camera_add_device, + .remove = pxa_camera_remove_device, + .suspend = pxa_camera_suspend, + .resume = pxa_camera_resume, + .set_fmt_cap = pxa_camera_set_fmt_cap, + .try_fmt_cap = pxa_camera_try_fmt_cap, + .init_videobuf = pxa_camera_init_videobuf, + .reqbufs = pxa_camera_reqbufs, + .poll = pxa_camera_poll, + .querycap = pxa_camera_querycap, + .try_bus_param = pxa_camera_try_bus_param, + .set_bus_param = pxa_camera_set_bus_param, +}; + +.add and .remove methods are called when a sensor is attached to or detached +from the host, apart from performing host-internal tasks they shall also call +sensor driver's .init and .release methods respectively. .suspend and .resume +methods implement host's power-management functionality and its their +responsibility to call respective sensor's methods. .try_bus_param and +.set_bus_param are used to negotiate physical connection parameters between the +host and the sensor. .init_videobuf is called by soc-camera core when a +video-device is opened, further video-buffer management is implemented completely +by the specific camera host driver. The rest of the methods are called from +respective V4L2 operations. + +Camera API +---------- + +Sensor drivers can use struct soc_camera_link, typically provided by the +platform, and used to specify to which camera host bus the sensor is connected, +and arbitrarily provide platform .power and .reset methods for the camera. +soc_camera_device_register() and soc_camera_device_unregister() functions are +used to add a sensor driver to or remove one from the system. The registration +function takes a pointer to struct soc_camera_device as the only parameter. +This struct can be initialized as follows: + + /* link to driver operations */ + icd->ops = &mt9m001_ops; + /* link to the underlying physical (e.g., i2c) device */ + icd->control = &client->dev; + /* window geometry */ + icd->x_min = 20; + icd->y_min = 12; + icd->x_current = 20; + icd->y_current = 12; + icd->width_min = 48; + icd->width_max = 1280; + icd->height_min = 32; + icd->height_max = 1024; + icd->y_skip_top = 1; + /* camera bus ID, typically obtained from platform data */ + icd->iface = icl->bus_id; + +struct soc_camera_ops provides .probe and .remove methods, which are called by +the soc-camera core, when a camera is matched against or removed from a camera +host bus, .init, .release, .suspend, and .resume are called from the camera host +driver as discussed above. Other members of this struct provide respective V4L2 +functionality. + +struct soc_camera_device also links to an array of struct soc_camera_data_format, +listing pixel formats, supported by the camera. + +-- +Author: Guennadi Liakhovetski <g.liakhovetski@gmx.de> |
