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 parking interface in the Linux kernel. -+ -+ -+The interface -+------------- -+The interface works as follows: Writing an integer value to -+/sys/block/*/queue/protect will park the respective drive and freeze -+the block layer queue for the specified number of seconds. When the -+timeout expires and no further disk park request has been issued in -+the meantime, the queue is unfrozen and accumulated I/O operations are -+performed. -+ -+IMPORTANT NOTE: -+Not all ATA drives implement IDLE IMMEDIATE with UNLOAD FEATURE and -+quite a few of those that do so, don't report this capability as -+described in the specs. When a disk park has been requested through -+sysfs as described above, the kernel will try to determine if the -+drive supports the UNLOAD FEATURE by default. The kernel will only -+rely on the IDLE IMMEDIATE with UNLOAD FEATURE command if it is -+convinced that this command is actually supported by the disk drive; -+otherwise, it will fall back to STANDBY IMMEDIATE. Resuming from the -+latter will take much longer and it is generally more likely to have a -+negative impact on the drive's lifetime due to the inclease of spin -+down and up cycles. If you want to use this interface in a shock -+protection framework and you know that your drive does indeed support -+the IDLE IMMEDIATE with UNLOAD FEATURE command despite not saying so, -+you can force the kernel to issue that command by doing the following -+on the command line: -+# echo -n unload > /sys/block/sda/queue/protect_method -+(replace sda by the drive identifier as appropriate). -+ -+/sys/block/*/queue/protect_method accepts auto, unload and standby -+respectively. Reading from protect_method shows the available options -+surrounding the active one with brackets. When auto is active, this -+will change to whatever the kernel sees fit after the next disk park -+command has been issued. -+ -+ -+References -+---------- -+ -+There are several laptops from different brands 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 poiters at different projects aiming at an implementation of shock -+protection on different systeems. Unfortunately, I only know of a -+single project which, although still considered experimental, is fit -+for use. Please feel free to add projects that have been the victims -+of my ignorance. -+ -+- http://www.thinkwiki.org/wiki/HDAPS -+ See this page for information about Linux support of the hard disk -+ active protection syystem as implemented in IBM/Lenovo Thinkpads. -+ -+ -+CREDITS -+------- -+ -+The patch to implement the interface described in this file has -+originally been published by Jon Escombe <lists@...>. -+ -+ -+05 Dec 2006, Elias Oltmanns <eo@...> -diff --git a/block/blk-core.c b/block/blk-core.c -index 2a438a9..5affbf3 100644 ---- a/block/blk-core.c -+++ b/block/blk-core.c -@@ -320,6 +320,46 @@ void blk_unplug(struct request_queue *q) - } - EXPORT_SYMBOL(blk_unplug); - -+/* -+ * Issue lower level unprotect function if no timers are pending. -+ */ -+void blk_unfreeze_work(struct work_struct *work) -+{ -+ struct request_queue *q = container_of(work, struct request_queue, unfreeze_work); -+ int pending; -+ unsigned long flags; -+ -+ spin_lock_irqsave(q->queue_lock, flags); -+ pending = timer_pending(&q->unfreeze_timer); -+ spin_unlock_irqrestore(q->queue_lock, flags); -+ if (!pending) -+ q->issue_unprotect_fn(q); -+} -+ -+/* -+ * Called when the queue freeze timeout expires... -+ */ -+void blk_unfreeze_timeout(unsigned long data) -+{ -+ struct request_queue *q = (struct request_queue *) data; -+ -+ kblockd_schedule_work(&q->unfreeze_work); -+} -+ -+/* -+ * The lower level driver parks and freezes the queue, and this block layer -+ * function sets up the freeze timeout timer on return.
