| * ide: Implement disk shock protection support (v4)Elias Oltmanns2008-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On user request (through sysfs), the IDLE IMMEDIATE command with UNLOAD FEATURE as specified in ATA-7 is issued to the device and processing of the request queue is stopped thereafter until the specified timeout expires or user space asks to resume normal operation. This is supposed to prevent the heads of a hard drive from accidentally crashing onto the platter when a heavy shock is anticipated (like a falling laptop expected to hit the floor). Port resets are deferred whenever a device on that port is in the parked state. v3: Elias Oltmanns <eo@nebensachen.de> wrote: [...] > >> 1.

Additionally, we should plug the queue when enqueueing the unpark request because there is no guarantee that the park timeout has not expired by then. Even though the chance for that to happen is very slim, the request might end up hanging in the queue until the next I/O operation is queued up. While at it, clean up the code a little: - make issue_park_cmd() a function of type void since nobody cares for the return value anyway; - use blk_start_queueing() instead of __blk_run_queue() since we don't have to worry about recursion; - remove a superfluous pointer deference in task_no_data_intr().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Follow-up to commit 5c05ff68b9a9b40a9be949497e0aa980185565cf ("ide: switch to DMA-mapping API"): * pci_{alloc,free}_consistent() -> dma_{alloc,free}_coherent() in ide_{allocate,release}_dma_engine(). * Add ->prd_max_nents and ->prd_ent_size fields to ide_hwif_t (+ set default values in ide_allocate_dma_engine()). * Make ide_{allocate,release}_dma_engine() available also for CONFIG_BLK_DEV_IDEDMA_SFF=n.
