+/*****************************************/
+Kernel Connector.
+/*****************************************/
+
+Kernel connector - new netlink based userspace <-> kernel space easy
+to use communication module.
+
+Connector driver adds possibility to connect various agents using
+netlink based network. One must register callback and
+identifier. When driver receives special netlink message with
+appropriate identifier, appropriate callback will be called.
+
+From the userspace point of view it's quite straightforward:
+
+ socket();
+ bind();
+ send();
+ recv();
+
+But if kernelspace want to use full power of such connections, driver
+writer must create special sockets, must know about struct sk_buff
+handling... Connector allows any kernelspace agents to use netlink
+based networking for inter-process communication in a significantly
+easier way:
+
+int cn_add_callback(struct cb_id *id, char *name, void (*callback) (void *));
+void cn_netlink_send(struct cn_msg *msg, u32 __group, int gfp_mask);
+
+struct cb_id
+{
+ __u32 idx;
+ __u32 val;
+};
+
+idx and val are unique identifiers which must be registered in
+connector.h for in-kernel usage. void (*callback) (void *) - is a
+callback function which will be called when message with above idx.val
+will be received by connector core. Argument for that function must
+be dereferenced to struct cn_msg *.
+
+struct cn_msg
+{
+ struct cb_id id;
+
+ __u32 seq;
+ __u32 ack;
+
+ __u32 len; /* Length of the following data */
+ __u8 data[0];
+};
+
+/*****************************************/
+Connector interfaces.
+/*****************************************/
+
+int cn_add_callback(struct cb_id *id, char *name, void (*callback) (void *));
+
+Registers new callback with connector core.
+
+struct cb_id *id - unique connector's user identifier.
+ It must be registered in connector.h for legal in-kernel users.
+char *name - connector's callback symbolic name.
+void (*callback) (void *) - connector's callback.
+ Argument must be dereferenced to struct cn_msg *.
+
+void cn_del_callback(struct cb_id *id);
+
+Unregisters new callback with connector core.
+
+struct cb_id *id - unique connector's user identifier.
+
+void cn_netlink_send(struct cn_msg *msg, u32 __groups, int gfp_mask);
+
+Sends message to the specified groups. It can be safely called from
+any context, but may silently fail under strong memory pressure.
+
+struct cn_msg * - message header(with attached data).
+u32 __group - destination group.
+ If __group is zero, then appropriate group will
+ be searched through all registered connector users,
+ and message will be delivered to the group which was
+ created for user with the same ID as in msg.
+ If __group is not zero, then message will be delivered
+ to the specified group.
+int gfp_mask - GFP mask.
+
+Note: When registering new callback user, connector core assigns
+netlink group to the user which is equal to it's id.idx.
+
+/*****************************************/
+Protocol description.
+/*****************************************/
+
+Current offers transport layer with fixed header. Recommended
+protocol which uses such header is following:
+
+msg->seq and msg->ack are used to determine message genealogy. When
+someone sends message it puts there locally unique sequence and random
+acknowledge numbers. Sequence number may be copied into
+nlmsghdr->nlmsg_seq too.
+
+Sequence number is incremented with each message to be sent.
+
+If we expect reply to our message, then sequence number in received
+message MUST be the same as in original message, and acknowledge
+number MUST be the same + 1.
+
+If we receive message and it's sequence number is not equal to one we
+are expecting, then it is new message. If we receive message and it's
+sequence number is the same as one we are expecting, but it's
+acknowledge is not equal acknowledge number in original message + 1,
+then it is new message.
+
+Obviously, protocol header contains above id.
+
+connector allows event notification in the following form: kernel
+driver or userspace process can ask connector to notify it when
+selected id's will be turned on or off(registered or unregistered it's
+callback). It is done by sending special command to connector
+driver(it also registers itself with id={-1, -1}).
+
+As example of usage Documentation/connector now contains cn_test.c -
+testing module which uses connector to request notification and to
+send messages.
+
+/*****************************************/
+Reliability.
+/*****************************************/
+
+Netlink itself is not reliable protocol, that means that messages can
+be lost due to memory pressure or process' receiving queue overflowed,
+so caller is warned must be prepared. That is why struct cn_msg [main
+connector's message header] contains u32 seq and u32 ack fields.

+Apple Touchpad Driver (appletouch)
+----------------------------------
+ Copyright (C) 2005 Stelian Pop <stelian@popies.net>
+
+appletouch is a Linux kernel driver for the USB touchpad found on post
+February 2005 Apple Alu Powerbooks.
+
+This driver is derived from Johannes Berg's appletrackpad driver[1], but it has
+been improved in some areas:
+ * appletouch is a full kernel driver, no userspace program is necessary
+ * appletouch can be interfaced with the synaptics X11 driver, in order
+ to have touchpad acceleration, scrolling, etc.
+
+Credits go to Johannes Berg for reverse-engineering the touchpad protocol,
+Frank Arnold for further improvements, and Alex Harper for some additional
+information about the inner workings of the touchpad sensors.
+
+Usage:
+------
+
+In order to use the touchpad in the basic mode, compile the driver and load
+the module. A new input device will be detected and you will be able to read
+the mouse data from /dev/input/mice (using gpm, or X11).
+
+In X11, you can configure the touchpad to use the synaptics X11 driver, which
+will give additional functionalities, like acceleration, scrolling, 2 finger
+tap for middle button mouse emulation, 3 finger tap for right button mouse
+emulation, etc. In order to do this, make sure you're using a recent version of
+the synaptics driver (tested with 0.14.2, available from [2]), and configure a
+new input device in your X11 configuration file (take a look below for an
+example). For additional configuration, see the synaptics driver documentation.
+

+
+Fuzz problems:
+--------------
+
+The touchpad sensors are very sensitive to heat, and will generate a lot of
+noise when the temperature changes. This is especially true when you power-on
+the laptop for the first time.
+
+The appletouch driver tries to handle this noise and auto adapt itself, but it
+is not perfect. If finger movements are not recognized anymore, try reloading
+the driver.
+
+You can activate debugging using the 'debug' module parameter. A value of 0
+deactivates any debugging, 1 activates tracing of invalid samples, 2 activates
+full tracing (each sample is being traced):
+ modprobe appletouch debug=1
+ or
+ echo "1" > /sys/module/appletouch/parameters/debug

Driver Interface -- OBSOLETE, DO NOT USE!
----------------*************************
+
+Note: pm_register(), pm_access(), pm_dev_idle() and friends are
+obsolete. Please do not use them. Instead you should properly hook
+your driver into the driver model, and use its suspend()/resume()
+callbacks to do this kind of stuff.
+
If you are writing a new driver or maintaining an old driver, it
should include power management support. Without power management
support, a single driver may prevent a system with power management

+ Each SCSI command is represented with struct scsi_cmnd (== scmd). A
+scmd has two list_head's to link itself into lists. The two are
+scmd->list and scmd->eh_entry. The former is used for free list or
+per-device allocated scmd list and not of much interest to this EH
+discussion. The latter is used for completion and EH lists and unless
+otherwise stated scmds are always linked using scmd->eh_entry in this
+discussion.
+
+
+[1-2] How do scmd's get completed?
+
+ Once LLDD gets hold of a scmd, either the LLDD will complete the
+command by calling scsi_done callback passed from midlayer when
+invoking hostt->queuecommand() or SCSI midlayer will time it out.
+
+
+[1-2-1] Completing a scmd w/ scsi_done
+
+ For all non-EH commands, scsi_done() is the completion callback. It
+does the following.
+
+ 1. Delete timeout timer. If it fails, it means that timeout timer
+ has expired and is going to finish the command. Just return.
+
+ 2. Link scmd to per-cpu scsi_done_q using scmd->en_entry
+
+ 3. Raise SCSI_SOFTIRQ
+
+ SCSI_SOFTIRQ handler scsi_softirq calls scsi_decide_disposition() to
+determine what to do with the command. scsi_decide_disposition()
+looks at the scmd->result value and sense data to determine what to do
+with the command.
+
+ - SUCCESS
+ scsi_finish_command() is invoked for the command. The
+ function does some maintenance choirs and notify completion by
+ calling scmd->done() callback, which, for fs requests, would
+ be HLD completion callback - sd:sd_rw_intr, sr:rw_intr,
+ st:st_intr.
+
+ - NEEDS_RETRY
+ - ADD_TO_MLQUEUE
+ scmd is requeued to blk queue.
+
+ - otherwise
+ scsi_eh_scmd_add(scmd, 0) is invoked for the command. See
+ [1-3] for details of this funciton.
+
+
+[1-2-2] Completing a scmd w/ timeout
+
+ The timeout handler is scsi_times_out(). When a timeout occurs, this
+function
+
+ 1. invokes optional hostt->eh_timedout() callback. Return value can
+ be one of
+
+ - EH_HANDLED
+ This indicates that eh_timedout() dealt with the timeout. The
+ scmd is passed to __scsi_done() and thus linked into per-cpu
+ scsi_done_q. Normal command completion described in [1-2-1]
+ follows.
+
+ - EH_RESET_TIMER
+ This indicates that more time is required to finish the
+ command. Timer is restarted. This action is counted as a
+ retry and only allowed scmd->allowed + 1(!) times. Once the
+ limit is reached, action for EH_NOT_HANDLED is taken instead.
+
+ *NOTE* This action is racy as the LLDD could finish the scmd
+ after the timeout has expired but before it's added back. In
+ such cases, scsi_done() would think that timeout has occurred
+ and return without doing anything. We lose completion and the
+ command will time out again.
+
+ - EH_NOT_HANDLED
+ This is the same as when eh_timedout() callback doesn't exist.
+ Step #2 is taken.
+
+ 2. scsi_eh_scmd_add(scmd, SCSI_EH_CANCEL_CMD) is invoked for the
+ command. See [1-3] for more information.
+
+
+[1-3] How EH takes over
+
+ scmds enter EH via scsi_eh_scmd_add(), which does the following.
+
+ 1. Turns on scmd->eh_eflags as requested. It's 0 for error
+ completions and SCSI_EH_CANCEL_CMD for timeouts.
+
+ 2. Links scmd->eh_entry to shost->eh_cmd_q
+
+ 3. Sets SHOST_RECOVERY bit in shost->shost_state
+
+ 4. Increments shost->host_failed
+
+ 5. Wakes up SCSI EH thread if shost->host_busy == shost->host_failed
+
+ As can be seen above, once any scmd is added to shost->eh_cmd_q,
+SHOST_RECOVERY shost_state bit is turned on. This prevents any new
+scmd to be issued from blk queue to the host; eventually, all scmds on
+the host either complete normally, fail and get added to eh_cmd_q, or
+time out and get added to shost->eh_cmd_q.
+
+ If all scmds either complete or fail, the number of in-flight scmds
+becomes equal to the number of failed scmds - i.e. shost->host_busy ==
+shost->host_failed. This wakes up SCSI EH thread. So, once woken up,
+SCSI EH thread can expect that all in-flight commands have failed and
+are linked on shost->eh_cmd_q.
+
+ Note that this does not mean lower layers are quiescent. If a LLDD
+completed a scmd with error status, the LLDD and lower layers are
+assumed to forget about the scmd at that point. However, if a scmd
+has timed out, unless hostt->eh_timedout() made lower layers forget
+about the scmd, which currently no LLDD does, the command is still
+active as long as lower layers are concerned and completion could
+occur at any time. Of course, all such completions are ignored as the
+timer has already expired.
+
+ We'll talk about how SCSI EH takes actions to abort - make LLDD
+forget about - timed out scmds later.
+
+
+[2] How SCSI EH works
+
+ LLDD's can implement SCSI EH actions in one of the following two
+ways.
+
+ - Fine-grained EH callbacks
+ LLDD can implement fine-grained EH callbacks and let SCSI
+ midlayer drive error handling and call appropriate callbacks.
+ This will be dicussed further in [2-1].
+
+ - eh_strategy_handler() callback
+ This is one big callback which should perform whole error
+ handling. As such, it should do all choirs SCSI midlayer
+ performs during recovery. This will be discussed in [2-2].
+
+ Once recovery is complete, SCSI EH resumes normal operation by
+calling scsi_restart_operations(), which
+
+ 1. Checks if door locking is needed and locks door.
+
+ 2. Clears SHOST_RECOVERY shost_state bit
+
+ 3. Wakes up waiters on shost->host_wait. This occurs if someone
+ calls scsi_block_when_processing_errors() on the host.
+ (*QUESTION* why is it needed? All operations will be blocked
+ anyway after it reaches blk queue.)
+
+ 4. Kicks queues in all devices on the host in the asses
+
+
+[2-1] EH through fine-grained callbacks
+
+[2-1-1] Overview
+
+ If eh_strategy_handler() is not present, SCSI midlayer takes charge
+of driving error handling. EH's goals are two - make LLDD, host and
+device forget about timed out scmds and make them ready for new
+commands. A scmd is said to be recovered if the scmd is forgotten by
+lower layers and lower layers are ready to process or fail the scmd
+again.
+
+ To achieve these goals, EH performs recovery actions with increasing
+severity. Some actions are performed by issueing SCSI commands and
+others are performed by invoking one of the following fine-grained
+hostt EH callbacks. Callbacks may be omitted and omitted ones are
+considered to fail always.
+
+int (* eh_abort_handler)(struct scsi_cmnd *);
+int (* eh_device_reset_handler)(struct scsi_cmnd *);
+int (* eh_bus_reset_handler)(struct scsi_cmnd *);
+int (* eh_host_reset_handler)(struct scsi_cmnd *);
+
+ Higher-severity actions are taken only when lower-severity actions
+cannot recover some of failed scmds. Also, note that failure of the
+highest-severity action means EH failure and results in offlining of
+all unrecovered devices.
+
+ During recovery, the following rules are followed
+
+ - Recovery actions are performed on failed scmds on the to do list,
+ eh_work_q. If a recovery action succeeds for a scmd, recovered
+ scmds are removed from eh_work_q.
+
+ Note that single recovery action on a scmd can recover multiple
+ scmds. e.g. resetting a device recovers all failed scmds on the
+ device.
+
+ - Higher severity actions are taken iff eh_work_q is not empty after
+ lower severity actions are complete.
+
+ - EH reuses failed scmds to issue commands for recovery. For
+ timed-out scmds, SCSI EH ensures that LLDD forgets about a scmd
+ before reusing it for EH commands.
+
+ When a scmd is recovered, the scmd is moved from eh_work_q to EH
+local eh_done_q using scsi_eh_finish_cmd(). After all scmds are
+recovered (eh_work_q is empty), scsi_eh_flush_done_q() is invoked to
+either retry or error-finish (notify upper layer of failure) recovered
+scmds.
+
+ scmds are retried iff its sdev is still online (not offlined during
+EH), REQ_FAILFAST is not set and ++scmd->retries is less than
+scmd->allowed.
+
+
+[2-1-2] Flow of scmds through EH
+
+ 1. Error completion / time out
+ ACTION: scsi_eh_scmd_add() is invoked for scmd
+ - set scmd->eh_eflags
+ - add scmd to shost->eh_cmd_q
+ - set SHOST_RECOVERY
+ - shost->host_failed++
+ LOCKING: shost->host_lock
+
+ 2. EH starts
+ ACTION: move all scmds to EH's local eh_work_q. shost->eh_cmd_q
+ is cleared.
+ LOCKING: shost->host_lock (not strictly necessary, just for
+ consistency)
+
+ 3. scmd recovered
+ ACTION: scsi_eh_finish_cmd() is invoked to EH-finish scmd
+ - shost->host_failed--
+ - clear scmd->eh_eflags
+ - scsi_setup_cmd_retry()
+ - move from local eh_work_q to local eh_done_q
+ LOCKING: none
+
+ 4. EH completes
+ ACTION: scsi_eh_flush_done_q() retries scmds or notifies upper
+ layer of failure.
+ - scmd is removed from eh_done_q and scmd->eh_entry is cleared
+ - if retry is necessary, scmd is requeued using
+ scsi_queue_insert()
+ - otherwise, scsi_finish_command() is invoked for scmd
+ LOCKING: queue or finish function performs appropriate locking
+
+
+[2-1-3] Flow of control
+
+ EH through fine-grained callbacks start from scsi_unjam_host().
+
+<<scsi_unjam_host>>
+
+ 1. Lock shost->host_lock, splice_init shost->eh_cmd_q into local
+ eh_work_q and unlock host_lock. Note that shost->eh_cmd_q is
+ cleared by this action.
+
+ 2. Invoke scsi_eh_get_sense.
+
+ <<scsi_eh_get_sense>>
+
+ This action is taken for each error-completed
+ (!SCSI_EH_CANCEL_CMD) commands without valid sense data. Most
+ SCSI transports/LLDDs automatically acquire sense data on
+ command failures (autosense). Autosense is recommended for
+ performance reasons and as sense information could get out of
+ sync inbetween occurrence of CHECK CONDITION and this action.
+
+ Note that if autosense is not supported, scmd->sense_buffer
+ contains invalid sense data when error-completing the scmd
+ with scsi_done(). scsi_decide_disposition() always returns
+ FAILED in such cases thus invoking SCSI EH. When the scmd
+ reaches here, sense data is acquired and
+ scsi_decide_disposition() is called again.
+
+ 1. Invoke scsi_request_sense() which issues REQUEST_SENSE
+ command. If fails, no action. Note that taking no action
+ causes higher-severity recovery to be taken for the scmd.
+
+ 2. Invoke scsi_decide_disposition() on the scmd
+
+ - SUCCESS
+ scmd->retries is set to scmd->allowed preventing
+ scsi_eh_flush_done_q() from retrying the scmd and
+ scsi_eh_finish_cmd() is invoked.
+
+ - NEEDS_RETRY
+ scsi_eh_finish_cmd() invoked
+
+ - otherwise
+ No action.
+
+ 3. If !list_empty(&eh_work_q), invoke scsi_eh_abort_cmds().
+
+ <<scsi_eh_abort_cmds>>
+
+ This action is taken for each timed out command.
+ hostt->eh_abort_handler() is invoked for each scmd. The
+ handler returns SUCCESS if it has succeeded to make LLDD and
+ all related hardware forget about the scmd.
+
+ If a timedout scmd is successfully aborted and the sdev is
+ either offline or ready, scsi_eh_finish_cmd() is invoked for
+ the scmd. Otherwise, the scmd is left in eh_work_q for
+ higher-severity actions.
+
+ Note that both offline and ready status mean that the sdev is
+ ready to process new scmds, where processing also implies
+ immediate failing; thus, if a sdev is in one of the two
+ states, no further recovery action is needed.
+
+ Device readiness is tested using scsi_eh_tur() which issues
+ TEST_UNIT_READY command. Note that the scmd must have been
+ aborted successfully before reusing it for TEST_UNIT_READY.
+
+ 4. If !list_empty(&eh_work_q), invoke scsi_eh_ready_devs()
+
+ <<scsi_eh_ready_devs>>
+
+ This function takes four increasingly more severe measures to
+ make failed sdevs ready for new commands.
+
+ 1. Invoke scsi_eh_stu()
+
+ <<scsi_eh_stu>>
+
+ For each sdev which has failed scmds with valid sense data
+ of which scsi_check_sense()'s verdict is FAILED,
+ START_STOP_UNIT command is issued w/ start=1. Note that
+ as we explicitly choose error-completed scmds, it is known
+ that lower layers have forgotten about the scmd and we can
+ reuse it for STU.
+
+ If STU succeeds and the sdev is either offline or ready,
+ all failed scmds on the sdev are EH-finished with
+ scsi_eh_finish_cmd().
+
+ *NOTE* If hostt->eh_abort_handler() isn't implemented or
+ failed, we may still have timed out scmds at this point
+ and STU doesn't make lower layers forget about those
+ scmds. Yet, this function EH-finish all scmds on the sdev
+ if STU succeeds leaving lower layers in an inconsistent
+ state. It seems that STU action should be taken only when
+ a sdev has no timed out scmd.
+
+ 2. If !list_empty(&eh_work_q), invoke scsi_eh_bus_device_reset().
+
+ <<scsi_eh_bus_device_reset>>
+
+ This action is very similar to scsi_eh_stu() except that,
+ instead of issuing STU, hostt->eh_device_reset_handler()
+ is used. Also, as we're not issuing SCSI commands and
+ resetting clears all scmds on the sdev, there is no need
+ to choose error-completed scmds.
+
+ 3. If !list_empty(&eh_work_q), invoke scsi_eh_bus_reset()
+
+ <<scsi_eh_bus_reset>>
+
+ hostt->eh_bus_reset_handler() is invoked for each channel
+ with failed scmds. If bus reset succeeds, all failed
+ scmds on all ready or offline sdevs on the channel are
+ EH-finished.
+
+ 4. If !list_empty(&eh_work_q), invoke scsi_eh_host_reset()
+
+ <<scsi_eh_host_reset>>
+
+ This is the last resort. hostt->eh_host_reset_handler()
+ is invoked. If host reset succeeds, all failed scmds on
+ all ready or offline sdevs on the host are EH-finished.
+
+ 5. If !list_empty(&eh_work_q), invoke scsi_eh_offline_sdevs()
+
+ <<scsi_eh_offline_sdevs>>
+
+ Take all sdevs which still have unrecovered scmds offline
+ and EH-finish the scmds.
+
+ 5. Invoke scsi_eh_flush_done_q().
+
+ <<scsi_eh_flush_done_q>>
+
+ At this point all scmds are recovered (or given up) and
+ put on eh_done_q by scsi_eh_finish_cmd(). This function
+ flushes eh_done_q by either retrying or notifying upper
+ layer of failure of the scmds.
+
+
+[2-2] EH through hostt->eh_strategy_handler()
+
+ hostt->eh_strategy_handler() is invoked in the place of
+scsi_unjam_host() and it is responsible for whole recovery process.
+On completion, the handler should have made lower layers forget about
+all failed scmds and either ready for new commands or offline. Also,
+it should perform SCSI EH maintenance choirs to maintain integrity of
+SCSI midlayer. IOW, of the steps described in [2-1-2], all steps
+except for #1 must be implemented by eh_strategy_handler().
+
+
+[2-2-1] Pre hostt->eh_strategy_handler() SCSI midlayer conditions
+
+ The following conditions are true on entry to the handler.
+
+ - Each failed scmd's eh_flags field is set appropriately.
+
+ - Each failed scmd is linked on scmd->eh_cmd_q by scmd->eh_entry.
+
+ - SHOST_RECOVERY is set.
+
+ - shost->host_failed == shost->host_busy
+
+
+[2-2-2] Post hostt->eh_strategy_handler() SCSI midlayer conditions
+
+ The following conditions must be true on exit from the handler.
+
+ - shost->host_failed is zero.
+
+ - Each scmd's eh_eflags field is cleared.
+
+ - Each scmd is in such a state that scsi_setup_cmd_retry() on the
+ scmd doesn't make any difference.
+
+ - shost->eh_cmd_q is cleared.
+
+ - Each scmd->eh_entry is cleared.
+
+ - Either scsi_queue_insert() or scsi_finish_command() is called on
+ each scmd. Note that the handler is free to use scmd->retries and
+ ->allowed to limit the number of retries.
+
+
+[2-2-3] Things to consider
+
+ - Know that timed out scmds are still active on lower layers. Make
+ lower layers forget about them before doing anything else with
+ those scmds.
+
+ - For consistency, when accessing/modifying shost data structure,
+ grab shost->host_lock.
+
+ - On completion, each failed sdev must have forgotten about all
+ active scmds.
+
+ - On completion, each failed sdev must be ready for new commands or
+ offline.

- * Packet writing layer for ATAPI and SCSI CD-R, CD-RW, DVD-R, and
- * DVD-RW devices (aka an exercise in block layer masturbation)
+ * Packet writing layer for ATAPI and SCSI CD-RW, DVD+RW, DVD-RW and
+ * DVD-RAM devices.
*
+ * Theory of operation:
*
- * TODO: (circa order of when I will fix it)
- * - Only able to write on CD-RW media right now.
- * - check host application code on media and set it in write page
- * - interface for UDF <-> packet to negotiate a new location when a write
- * fails.
- * - handle OPC, especially for -RW media
+ * At the lowest level, there is the standard driver for the CD/DVD device,
+ * typically ide-cd.c or sr.c. This driver can handle read and write requests,
+ * but it doesn't know anything about the special restrictions that apply to
+ * packet writing. One restriction is that write requests must be aligned to
+ * packet boundaries on the physical media, and the size of a write request
+ * must be equal to the packet size. Another restriction is that a
+ * GPCMD_FLUSH_CACHE command has to be issued to the drive before a read
+ * command, if the previous command was a write.
*
- * Theory of operation:
+ * The purpose of the packet writing driver is to hide these restrictions from
+ * higher layers, such as file systems, and present a block device that can be
+ * randomly read and written using 2kB-sized blocks.
+ *
+ * The lowest layer in the packet writing driver is the packet I/O scheduler.
+ * Its data is defined by the struct packet_iosched and includes two bio
+ * queues with pending read and write requests. These queues are processed
+ * by the pkt_iosched_process_queue() function. The write requests in this
+ * queue are already properly aligned and sized. This layer is responsible for
+ * issuing the flush cache commands and scheduling the I/O in a good order.
*
- * We use a custom make_request_fn function that forwards reads directly to
- * the underlying CD device. Write requests are either attached directly to
- * a live packet_data object, or simply stored sequentially in a list for
- * later processing by the kcdrwd kernel thread. This driver doesn't use
- * any elevator functionally as defined by the elevator_s struct, but the
- * underlying CD device uses a standard elevator.
+ * The next layer transforms unaligned write requests to aligned writes. This
+ * transformation requires reading missing pieces of data from the underlying
+ * block device, assembling the pieces to full packets and queuing them to the
+ * packet I/O scheduler.
*
- * This strategy makes it possible to do very late merging of IO requests.
- * A new bio sent to pkt_make_request can be merged with a live packet_data
- * object even if the object is in the data gathering state.
+ * At the top layer there is a custom make_request_fn function that forwards
+ * read requests directly to the iosched queue and puts write requests in the
+ * unaligned write queue. A kernel thread performs the necessary read
+ * gathering to convert the unaligned writes to aligned writes and then feeds
+ * them to the packet I/O scheduler.

+ * Watchdog Timer Configuration
+ *
+ * The function of the watchdog timer is to reset the system automatically
+ * and is defined at I/O port 0120H and 0121H. To enable the watchdog timer
+ * and allow the system to reset, write appropriate values from the table
+ * below to I/O port 0120H and 0121H. To disable the timer, write a zero
+ * value to I/O port 0121H for the system to stop the watchdog function.
+ *
+ * The following describes how the timer should be programmed (according to
+ * the vendor documentation)
+ *
+ * Enabling Watchdog:
+ * MOV AX,000AH (enable, phase I)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000BH (enable, phase II)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000nH (set multiplier n, from 1-4)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000mH (set base timer m, from 0-F)
+ * MOV DX,0121H
+ * OUT DX,AX
+ *
+ * Reset timer:
+ * MOV AX,000mH (same as set base timer, above)
+ * MOV DX,0121H
+ * OUT DX,AX
+ *
+ * Disabling Watchdog:
+ * MOV AX,0000H (a zero value)
+ * MOV DX,0120H
+ * OUT DX,AX
+ *
+ * Watchdog timeout configuration values:
+ * N
+ * M | 1 2 3 4
+ * --|----------------------------------
+ * 0 | 0.5s 5s 50s 100s

+ This driver provides support for the IBM Hard Drive Active Protection
+ System (hdaps), which provides an accelerometer and other misc. data.
+ Supported laptops include the IBM ThinkPad T41, T42, T43, and R51.
+ The accelerometer data is readable via sysfs.
+
+ This driver also provides an input class device, allowing the
+ laptop to act as a pinball machine-esque mouse. This is off by
+ default but enabled via sysfs or the module parameter "mousedev".
+
+ Say Y here if you have an applicable laptop and want to experience
+ the awesome power of hdaps.

+ * interfaces to userspace.
+ *
+ * In addition to the basic SCSI core objects this transport class
+ * introduces two additional intermediate objects: The SAS PHY
+ * as represented by struct sas_phy defines an "outgoing" PHY on
+ * a SAS HBA or Expander, and the SAS remote PHY represented by
+ * struct sas_rphy defines an "incoming" PHY on a SAS Expander or
+ * end device. Note that this is purely a software concept, the
+ * underlying hardware for a PHY and a remote PHY is the exactly
+ * the same.
+ *
+ * There is no concept of a SAS port in this code, users can see
+ * what PHYs form a wide port based on the port_identifier attribute,
+ * which is the same for all PHYs in a port.

+ Say Y here if you want a VGA text console via the USB dongle or
+ want to support userland applications that utilize the driver's
+ display mode switching capabilities.
+
+ Note that this console supports VGA/EGA text mode only.
+
+ By default, the console part of the driver will not kick in when
+ the driver is initialized. If you want the driver to take over
+ one or more of the consoles, you need to specify the number of
+ the first and last consoles (starting at 1) as driver parameters.
+
+ For example, if the driver is compiled as a module:
+
+ modprobe sisusbvga first=1 last=5
+
+ If you use hotplug, add this to your modutils config files with
+ the "options" keyword, such as eg.
+
+ options sisusbvga first=1 last=5
+
+ If the driver is compiled into the kernel image, the parameters
+ must be given in the kernel command like, such as
+
+ sisusbvga.first=1 sisusbvga.last=5
+

+ * Implements the standard CRC-16:
* Width 16
* Poly 0x8005 (x^16 + x^15 + x^2 + 1)
* Init 0
*
- * For 1-wire devices, the CRC is stored inverted, LSB-first
- *
- * Example buffer with the CRC attached:
- * 31 32 33 34 35 36 37 38 39 C2 44
- *
- * The CRC over a buffer with the CRC attached is 0xB001.
- * So, if (crc16(0, buf, size) == 0xB001) then the buffer is valid.
