      ata: Add documentation for hard disk shock protection interface (v3) · 9c6102d4
      Elias Oltmanns authored
      Put some information (and pointers to more) into the kernel's doc tree,
      describing briefly the interface to the kernel's disk head unloading
      facility. Information about how to set up a complete shock protection
      system under GNU/Linux can be found on the web and is referenced
      accordingly.
      
      v3:
      Here is some final polish including various spelling corrections
      pointed out by Grant Grundler and Peter Moulder. Also, I have added some
      information about the timing constraints related to disk head parking.
      The patch looks more impressive than it really is and I think it would
      be alright just to incorporate it into the original patch so as not to
      clutter up the git log.

      ide: Implement disk shock protection support (v4) · 4abdc6ee
      Elias Oltmanns authored
      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.

      v4:
      Fix a memory leak due to a missing blk_put_request() in
      issue_park_cmd(). 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().

      Also,
      
      - leave in the possibility for optimizing away all debugging macros
      - add a PFX macro and prepend all printk calls with it for consistency
      - add debug macro calls in important driver paths
      - remove #if 0-ed code
      - mv restore_request -> ide_cd_restore_request
      - add a driver registration printk
      
      v2:
      failed_command can be NULL so check it before accessing it
      
      v3:
      fix another NULL ptr in debug statement

      ide: switch to DMA-mapping API part #2 · 2bbd57ca
      Bartlomiej Zolnierkiewicz authored
      Follow-up to commit 5c05ff68
      ("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.  Then convert au1xxx-ide.c,
        scc_pata.c and sgiioc4.c to use them.
      
      * Add missing ->init_dma method to scc_pata.
      
      This patch also fixes:
      - ->dmatable_cpu leak for au1xxx-ide
      - too early realease of ->dmatable_cpu for scc_pata
      - wrong amount of ->dmatable_cpu memory being freed for sgiioc4
      
      While at it:
      - remove superfluous ->dma_base check from ide_unregister()
      - return -ENOMEM on error in ide_release_dma_engine()
      - beautify error message in ide_release_dma_engine()
