+
+        <para>
+        This chapter describes how errors are handled under libata.
+        Readers are advised to read SCSI EH
+        (Documentation/scsi/scsi_eh.txt) and ATA exceptions doc first.

+        <para>
+        In libata, a command is represented with struct ata_queued_cmd
+        or qc.  qc's are preallocated during port initialization and
+        repetitively used for command executions.  Currently only one
+        qc is allocated per port but yet-to-be-merged NCQ branch
+        allocates one for each tag and maps each qc to NCQ tag 1-to-1.
+        </para>
+        <para>
+        libata commands can originate from two sources - libata itself
+        and SCSI midlayer.  libata internal commands are used for
+        initialization and error handling.  All normal blk requests
+        and commands for SCSI emulation are passed as SCSI commands
+        through queuecommand callback of SCSI host template.

+        <para>
+        First, qc is allocated and initialized using
+        ata_qc_new_init().  Although ata_qc_new_init() doesn't
+        implement any wait or retry mechanism when qc is not
+        available, internal commands are currently issued only during
+        initialization and error recovery, so no other command is
+        active and allocation is guaranteed to succeed.
+        </para>
+        <para>
+        Once allocated qc's taskfile is initialized for the command to
+        be executed.  qc currently has two mechanisms to notify
+        completion.  One is via qc->complete_fn() callback and the
+        other is completion qc->waiting.  qc->complete_fn() callback
+        is the asynchronous path used by normal SCSI translated
+        commands and qc->waiting is the synchronous (issuer sleeps in
+        process context) path used by internal commands.
+        </para>
+        <para>
+        Once initialization is complete, host_set lock is acquired
+        and the qc is issued.

+        <para>
+        All libata drivers use ata_scsi_queuecmd() as
+        hostt->queuecommand callback.  scmds can either be simulated
+        or translated.  No qc is involved in processing a simulated
+        scmd.  The result is computed right away and the scmd is
+        completed.
+        </para>
+        <para>
+        For a translated scmd, ata_qc_new_init() is invoked to
+        allocate a qc and the scmd is translated into the qc.  SCSI
+        midlayer's completion notification function pointer is stored
+        into qc->scsidone.
+        </para>
+        <para>
+        qc->complete_fn() callback is used for completion
+        notification.  ATA commands use ata_scsi_qc_complete() while
+        ATAPI commands use atapi_qc_complete().  Both functions end up
+        calling qc->scsidone to notify upper layer when the qc is
+        finished.  After translation is completed, the qc is issued
+        with ata_qc_issue().
+        </para>
+        <para>
+        Note that SCSI midlayer invokes hostt->queuecommand while
+        holding host_set lock, so all above occur while holding

+        </para>
+        <para>
+        For all non-ATAPI commands, whether it fails or not, almost
+        the same code path is taken and very little error handling
+        takes place.  A qc is completed with success status if it
+        succeeded, with failed status otherwise.
+        </para>
+        <para>
+        However, failed ATAPI commands require more handling as
+        REQUEST SENSE is needed to acquire sense data.  If an ATAPI
+        command fails, ata_qc_complete() is invoked with error status,
+        which in turn invokes atapi_qc_complete() via
+        qc->complete_fn() callback.
+        </para>
+        <para>
+        This makes atapi_qc_complete() set scmd->result to
+        SAM_STAT_CHECK_CONDITION, complete the scmd and return 1.  As
+        the sense data is empty but scmd->result is CHECK CONDITION,
+        SCSI midlayer will invoke EH for the scmd, and returning 1
+        makes ata_qc_complete() to return without deallocating the qc.
+        This leads us to ata_scsi_error() with partially completed qc.

+        <para>
+        ata_scsi_error() is the current hostt->eh_strategy_handler()
+        for libata.  As discussed above, this will be entered in two
+        cases - timeout and ATAPI error completion.  This function
+        calls low level libata driver's eng_timeout() callback, the
+        standard callback for which is ata_eng_timeout().  It checks
+        if a qc is active and calls ata_qc_timeout() on the qc if so.
+        Actual error handling occurs in ata_qc_timeout().
+        </para>
+        <para>
+        If EH is invoked for timeout, ata_qc_timeout() stops BMDMA and
+        completes the qc.  Note that as we're currently in EH, we
+        cannot call scsi_done.  As described in SCSI EH doc, a
+        recovered scmd should be either retried with
+        scsi_queue_insert() or finished with scsi_finish_command().
+        Here, we override qc->scsidone with scsi_finish_command() and
+        calls ata_qc_complete().
+        </para>
+        <para>
+        If EH is invoked due to a failed ATAPI qc, the qc here is
+        completed but not deallocated.  The purpose of this
+        half-completion is to use the qc as place holder to make EH
+        code reach this place.  This is a bit hackish, but it works.
+        </para>
+        <para>
+        Once control reaches here, the qc is deallocated by invoking
+        __ata_qc_complete() explicitly.  Then, internal qc for REQUEST
+        SENSE is issued.  Once sense data is acquired, scmd is
+        finished by directly invoking scsi_finish_command() on the
+        scmd.  Note that as we already have completed and deallocated
+        the qc which was associated with the scmd, we don't need
+        to/cannot call ata_qc_complete() again.

+        <para>

+        <para>
+        Third, scattered EH code makes implementing low level drivers

+        should perform its part of error handling.  This can be error
+        prone and painful.

 4. The I/O scheduler
-I/O schedulers are now per queue. They should be runtime switchable and modular
-but aren't yet. Jens has most bits to do this, but the sysfs implementation is
-missing.
+I/O scheduler, a.k.a. elevator, is implemented in two layers.  Generic dispatch
+queue and specific I/O schedulers.  Unless stated otherwise, elevator is used
+to refer to both parts and I/O scheduler to specific I/O schedulers.
+
+Block layer implements generic dispatch queue in ll_rw_blk.c and elevator.c.
+The generic dispatch queue is responsible for properly ordering barrier
+requests, requeueing, handling non-fs requests and all other subtleties.
+
+Specific I/O schedulers are responsible for ordering normal filesystem
+requests.  They can also choose to delay certain requests to improve
+throughput or whatever purpose.  As the plural form indicates, there are
+multiple I/O schedulers.  They can be built as modules but at least one should
+be built inside the kernel.  Each queue can choose different one and can also
+change to another one dynamically.
 
 A block layer call to the i/o scheduler follows the convention elv_xxx(). This
 calls elevator_xxx_fn in the elevator switch (drivers/block/elevator.c). Oh,
