Description +-------------- + +This driver provides support for the accelerometer found in various Toshiba +laptops, being called "Toshiba HDD Protection - Shock Sensor" officialy, +and detects laptops automatically with this device. +On Windows, Toshiba provided software monitors this device and provides +automatic HDD protection (head unload) on sudden moves or harsh vibrations, +however, this driver only provides a notification via a sysfs file to let +userspace tools or daemons act accordingly, as well as providing a sysfs +file to set the desired protection level or sensor sensibility. + + +2. Interface +------------ + +This device comes with 3 methods: +_STA - Checks existence of the device, returning Zero if the device does not + exists or is not supported. +PTLV - Sets the desired protection level. +RSSS - Shuts down the HDD protection interface for a few seconds, + then restores normal operation. + +Note: +The presence of Solid State Drives (SSD) can make this driver to fail loading, +given the fact that such drives have no movable parts, and thus, not requiring +any "protection" as well as failing during the evaluation of the _STA method +found under this device. + + +3. Accelerometer axes +--------------------- + +This device does not report any axes, however, to query the sensor position +a couple HCI (Hardware Configuration Interface) calls (0x6D and 0xA6) are +provided to query such information, handled by the kernel module toshiba_acpi +since kernel version 3.15. + + +4.
