+
+ Error handling
+
+
+ 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.
+
+
+ Origins of commands
+
+ 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.
+
+
+ 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.
+
+
+
+ How commands are issued
+
+
+
+ Internal commands
+
+
+ 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.
+
+
+ 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.
+
+
+ Once initialization is complete, host_set lock is acquired
+ and the qc is issued.
+
+
+
+
+ SCSI commands
+
+
+ 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.
+
+
+ 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.
+
+
+ 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().
+
+
+ Note that SCSI midlayer invokes hostt->queuecommand while
+ holding host_set lock, so all above occur while holding
+ host_set lock.
+
+
+
+
+
+
+
+ How commands are processed
+
+ Depending on which protocol and which controller are used,
+ commands are processed differently. For the purpose of
+ discussion, a controller which uses taskfile interface and all
+ standard callbacks is assumed.
+
+
+ Currently 6 ATA command protocols are used. They can be
+ sorted into the following four categories according to how
+ they are processed.
+
+
+
+ ATA NO DATA or DMA
+
+
+ ATA_PROT_NODATA and ATA_PROT_DMA fall into this category.
+ These types of commands don't require any software
+ intervention once issued. Device will raise interrupt on
+ completion.
+
+
+
+
+ ATA PIO
+
+
+ ATA_PROT_PIO is in this category. libata currently
+ implements PIO with polling. ATA_NIEN bit is set to turn
+ off interrupt and pio_task on ata_wq performs polling and
+ IO.
+
+
+
+
+ ATAPI NODATA or DMA
+
+
+ ATA_PROT_ATAPI_NODATA and ATA_PROT_ATAPI_DMA are in this
+ category. packet_task is used to poll BSY bit after
+ issuing PACKET command. Once BSY is turned off by the
+ device, packet_task transfers CDB and hands off processing
+ to interrupt handler.
+
+
+
+
+ ATAPI PIO
+
+
+ ATA_PROT_ATAPI is in this category. ATA_NIEN bit is set
+ and, as in ATAPI NODATA or DMA, packet_task submits cdb.
+ However, after submitting cdb, further processing (data
+ transfer) is handed off to pio_task.
+
+
+
+
+
+
+ How commands are completed
+
+ Once issued, all qc's are either completed with
+ ata_qc_complete() or time out. For commands which are handled
+ by interrupts, ata_host_intr() invokes ata_qc_complete(), and,
+ for PIO tasks, pio_task invokes ata_qc_complete(). In error
+ cases, packet_task may also complete commands.
+
+
+ ata_qc_complete() does the following.
+
+
+
+
+
+
+ DMA memory is unmapped.
+
+
+
+
+
+ ATA_QCFLAG_ACTIVE is clared from qc->flags.
+
+
+
+
+
+ qc->complete_fn() callback is invoked. If the return value of
+ the callback is not zero. Completion is short circuited and
+ ata_qc_complete() returns.
+
+
+
+
+
+ __ata_qc_complete() is called, which does
+
+
+
+
+ qc->flags is cleared to zero.
+
+
+
+
+
+ ap->active_tag and qc->tag are poisoned.
+
+
+
+
+
+ qc->waiting is claread & completed (in that order).
+
+
+
+
+
+ qc is deallocated by clearing appropriate bit in ap->qactive.
+
+
+
+
+
+
+
+
+
+
+ So, it basically notifies upper layer and deallocates qc. One
+ exception is short-circuit path in #3 which is used by
+ atapi_qc_complete().
+
+
+ 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.
+
+
+ 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.
+
+
+ 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.
+
+
+
+
+ ata_scsi_error()
+
+ 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().
+
+
+ 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().
+
+
+ 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.
+
+
+ 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.
+
+
+
+
+ Problems with the current EH
+
+
+
+
+
+ Error representation is too crude. Currently any and all
+ error conditions are represented with ATA STATUS and ERROR
+ registers. Errors which aren't ATA device errors are treated
+ as ATA device errors by setting ATA_ERR bit. Better error
+ descriptor which can properly represent ATA and other
+ errors/exceptions is needed.
+
+
+
+
+
+ When handling timeouts, no action is taken to make device
+ forget about the timed out command and ready for new commands.
+
+
+
+
+
+ EH handling via ata_scsi_error() is not properly protected
+ from usual command processing. On EH entrance, the device is
+ not in quiescent state. Timed out commands may succeed or
+ fail any time. pio_task and atapi_task may still be running.
+
+
+
+
+
+ Too weak error recovery. Devices / controllers causing HSM
+ mismatch errors and other errors quite often require reset to
+ return to known state. Also, advanced error handling is
+ necessary to support features like NCQ and hotplug.
+
+
+
+
+
+ ATA errors are directly handled in the interrupt handler and
+ PIO errors in pio_task. This is problematic for advanced
+ error handling for the following reasons.
+
+
+ First, advanced error handling often requires context and
+ internal qc execution.
+
+
+ Second, even a simple failure (say, CRC error) needs
+ information gathering and could trigger complex error handling
+ (say, resetting & reconfiguring). Having multiple code
+ paths to gather information, enter EH and trigger actions
+ makes life painful.
+
+
+ Third, scattered EH code makes implementing low level drivers
+ difficult. Low level drivers override libata callbacks. If
+ EH is scattered over several places, each affected callbacks
+ should perform its part of error handling. This can be error
+ prone and painful.

+
+ ATA errors & exceptions
+
+
+ This chapter tries to identify what error/exception conditions exist
+ for ATA/ATAPI devices and describe how they should be handled in
+ implementation-neutral way.
+
+
+
+ The term 'error' is used to describe conditions where either an
+ explicit error condition is reported from device or a command has
+ timed out.
+
+
+
+ The term 'exception' is either used to describe exceptional
+ conditions which are not errors (say, power or hotplug events), or
+ to describe both errors and non-error exceptional conditions. Where
+ explicit distinction between error and exception is necessary, the
+ term 'non-error exception' is used.
+
+
+
+ Exception categories
+
+ Exceptions are described primarily with respect to legacy
+ taskfile + bus master IDE interface. If a controller provides
+ other better mechanism for error reporting, mapping those into
+ categories described below shouldn't be difficult.
+
+
+
+ In the following sections, two recovery actions - reset and
+ reconfiguring transport - are mentioned. These are described
+ further in .
+
+
+
+ HSM violation
+
+ This error is indicated when STATUS value doesn't match HSM
+ requirement during issuing or excution any ATA/ATAPI command.
+
+
+
+ Examples
+
+
+
+ ATA_STATUS doesn't contain !BSY && DRDY && !DRQ while trying
+ to issue a command.
+
+
+
+
+
+ !BSY && !DRQ during PIO data transfer.
+
+
+
+
+
+ DRQ on command completion.
+
+
+
+
+
+ !BSY && ERR after CDB tranfer starts but before the
+ last byte of CDB is transferred. ATA/ATAPI standard states
+ that "The device shall not terminate the PACKET command
+ with an error before the last byte of the command packet has
+ been written" in the error outputs description of PACKET
+ command and the state diagram doesn't include such
+ transitions.
+
+
+
+
+
+
+ In these cases, HSM is violated and not much information
+ regarding the error can be acquired from STATUS or ERROR
+ register. IOW, this error can be anything - driver bug,
+ faulty device, controller and/or cable.
+
+
+
+ As HSM is violated, reset is necessary to restore known state.
+ Reconfiguring transport for lower speed might be helpful too
+ as transmission errors sometimes cause this kind of errors.
+
+
+
+
+ ATA/ATAPI device error (non-NCQ / non-CHECK CONDITION)
+
+
+ These are errors detected and reported by ATA/ATAPI devices
+ indicating device problems. For this type of errors, STATUS
+ and ERROR register values are valid and describe error
+ condition. Note that some of ATA bus errors are detected by
+ ATA/ATAPI devices and reported using the same mechanism as
+ device errors. Those cases are described later in this
+ section.
+
+
+
+ For ATA commands, this type of errors are indicated by !BSY
+ && ERR during command execution and on completion.
+
+
+ For ATAPI commands,
+
+
+
+
+
+ !BSY && ERR && ABRT right after issuing PACKET
+ indicates that PACKET command is not supported and falls in
+ this category.
+
+
+
+
+
+ !BSY && ERR(==CHK) && !ABRT after the last
+ byte of CDB is transferred indicates CHECK CONDITION and
+ doesn't fall in this category.
+
+
+
+
+
+ !BSY && ERR(==CHK) && ABRT after the last byte
+ of CDB is transferred *probably* indicates CHECK CONDITION and
+ doesn't fall in this category.
+
+
+
+
+
+
+ Of errors detected as above, the followings are not ATA/ATAPI
+ device errors but ATA bus errors and should be handled
+ according to .
+
+
+
+
+
+ CRC error during data transfer
+
+
+ This is indicated by ICRC bit in the ERROR register and
+ means that corruption occurred during data transfer. Upto
+ ATA/ATAPI-7, the standard specifies that this bit is only
+ applicable to UDMA transfers but ATA/ATAPI-8 draft revision
+ 1f says that the bit may be applicable to multiword DMA and
+ PIO.
+
+
+
+
+
+ ABRT error during data transfer or on completion
+
+
+ Upto ATA/ATAPI-7, the standard specifies that ABRT could be
+ set on ICRC errors and on cases where a device is not able
+ to complete a command. Combined with the fact that MWDMA
+ and PIO transfer errors aren't allowed to use ICRC bit upto
+ ATA/ATAPI-7, it seems to imply that ABRT bit alone could
+ indicate tranfer errors.
+
+
+ However, ATA/ATAPI-8 draft revision 1f removes the part
+ that ICRC errors can turn on ABRT. So, this is kind of
+ gray area. Some heuristics are needed here.
+
+
+
+
+
+
+
+ ATA/ATAPI device errors can be further categorized as follows.
+
+
+
+
+
+ Media errors
+
+
+ This is indicated by UNC bit in the ERROR register. ATA
+ devices reports UNC error only after certain number of
+ retries cannot recover the data, so there's nothing much
+ else to do other than notifying upper layer.
+
+
+ READ and WRITE commands report CHS or LBA of the first
+ failed sector but ATA/ATAPI standard specifies that the
+ amount of transferred data on error completion is
+ indeterminate, so we cannot assume that sectors preceding
+ the failed sector have been transferred and thus cannot
+ complete those sectors successfully as SCSI does.
+
+
+
+
+
+ Media changed / media change requested error
+
+
+ <<TODO: fill here>>
+
+
+
+
+ Address error
+
+
+ This is indicated by IDNF bit in the ERROR register.
+ Report to upper layer.
+
+
+
+
+ Other errors
+
+
+ This can be invalid command or parameter indicated by ABRT
+ ERROR bit or some other error condition. Note that ABRT
+ bit can indicate a lot of things including ICRC and Address
+ errors. Heuristics needed.
+
+
+
+
+
+
+
+ Depending on commands, not all STATUS/ERROR bits are
+ applicable. These non-applicable bits are marked with
+ "na" in the output descriptions but upto ATA/ATAPI-7
+ no definition of "na" can be found. However,
+ ATA/ATAPI-8 draft revision 1f describes "N/A" as
+ follows.
+
+
+
+
+ 3.2.3.3a N/A
+
+
+ A keyword the indicates a field has no defined value in
+ this standard and should not be checked by the host or
+ device. N/A fields should be cleared to zero.
+
+
+
+
+
+
+
+ So, it seems reasonable to assume that "na" bits are
+ cleared to zero by devices and thus need no explicit masking.
+
+
+
+
+
+ ATAPI device CHECK CONDITION
+
+
+ ATAPI device CHECK CONDITION error is indicated by set CHK bit
+ (ERR bit) in the STATUS register after the last byte of CDB is
+ transferred for a PACKET command. For this kind of errors,
+ sense data should be acquired to gather information regarding
+ the errors. REQUEST SENSE packet command should be used to
+ acquire sense data.
+
+
+
+ Once sense data is acquired, this type of errors can be
+ handled similary to other SCSI errors. Note that sense data
+ may indicate ATA bus error (e.g. Sense Key 04h HARDWARE ERROR
+ && ASC/ASCQ 47h/00h SCSI PARITY ERROR). In such
+ cases, the error should be considered as an ATA bus error and
+ handled according to .
+
+
+
+
+
+ ATA device error (NCQ)
+
+
+ NCQ command error is indicated by cleared BSY and set ERR bit
+ during NCQ command phase (one or more NCQ commands
+ outstanding). Although STATUS and ERROR registers will
+ contain valid values describing the error, READ LOG EXT is
+ required to clear the error condition, determine which command
+ has failed and acquire more information.
+
+
+
+ READ LOG EXT Log Page 10h reports which tag has failed and
+ taskfile register values describing the error. With this
+ information the failed command can be handled as a normal ATA
+ command error as in and all
+ other in-flight commands must be retried. Note that this
+ retry should not be counted - it's likely that commands
+ retried this way would have completed normally if it were not
+ for the failed command.
+
+
+
+ Note that ATA bus errors can be reported as ATA device NCQ
+ errors. This should be handled as described in .
+
+
+
+ If READ LOG EXT Log Page 10h fails or reports NQ, we're
+ thoroughly screwed. This condition should be treated
+ according to .
+
+
+
+
+
+ ATA bus error
+
+
+ ATA bus error means that data corruption occurred during
+ transmission over ATA bus (SATA or PATA). This type of errors
+ can be indicated by
+
+
+
+
+
+
+ ICRC or ABRT error as described in .
+
+
+
+
+
+ Controller-specific error completion with error information
+ indicating transmission error.
+
+
+
+
+
+ On some controllers, command timeout. In this case, there may
+ be a mechanism to determine that the timeout is due to
+ transmission error.
+
+
+
+
+
+ Unknown/random errors, timeouts and all sorts of weirdities.
+
+
+
+
+
+
+ As described above, transmission errors can cause wide variety
+ of symptoms ranging from device ICRC error to random device
+ lockup, and, for many cases, there is no way to tell if an
+ error condition is due to transmission error or not;
+ therefore, it's necessary to employ some kind of heuristic
+ when dealing with errors and timeouts. For example,
+ encountering repetitive ABRT errors for known supported
+ command is likely to indicate ATA bus error.
+
+
+
+ Once it's determined that ATA bus errors have possibly
+ occurred, lowering ATA bus transmission speed is one of
+ actions which may alleviate the problem. See for more information.
+
+
+
+
+
+ PCI bus error
+
+
+ Data corruption or other failures during transmission over PCI
+ (or other system bus). For standard BMDMA, this is indicated
+ by Error bit in the BMDMA Status register. This type of
+ errors must be logged as it indicates something is very wrong
+ with the system. Resetting host controller is recommended.
+
+
+
+
+
+ Late completion
+
+
+ This occurs when timeout occurs and the timeout handler finds
+ out that the timed out command has completed successfully or
+ with error. This is usually caused by lost interrupts. This
+ type of errors must be logged. Resetting host controller is
+ recommended.
+
+
+
+
+
+ Unknown error (timeout)
+
+
+ This is when timeout occurs and the command is still
+ processing or the host and device are in unknown state. When
+ this occurs, HSM could be in any valid or invalid state. To
+ bring the device to known state and make it forget about the
+ timed out command, resetting is necessary. The timed out
+ command may be retried.
+
+
+
+ Timeouts can also be caused by transmission errors. Refer to
+ for more details.

+
+
+
+ EH recovery actions
+
+
+ This section discusses several important recovery actions.
+
+
+
+ Clearing error condition
+
+
+ Many controllers require its error registers to be cleared by
+ error handler. Different controllers may have different
+ requirements.
+
+
+
+ For SATA, it's strongly recommended to clear at least SError
+ register during error handling.
+
+
+
+
+ Reset
+
+
+ During EH, resetting is necessary in the following cases.
+
+
+
+
+
+
+ HSM is in unknown or invalid state
+
+
+
+
+
+ HBA is in unknown or invalid state
+
+
+
+
+
+ EH needs to make HBA/device forget about in-flight commands
+
+
+
+
+
+ HBA/device behaves weirdly
+
+
+
+
+
+
+ Resetting during EH might be a good idea regardless of error
+ condition to improve EH robustness. Whether to reset both or
+ either one of HBA and device depends on situation but the
+ following scheme is recommended.
+
+
+
+
+
+
+ When it's known that HBA is in ready state but ATA/ATAPI
+ device in in unknown state, reset only device.
+
+
+
+
+
+ If HBA is in unknown state, reset both HBA and device.
+
+
+
+
+
+
+ HBA resetting is implementation specific. For a controller
+ complying to taskfile/BMDMA PCI IDE, stopping active DMA
+ transaction may be sufficient iff BMDMA state is the only HBA
+ context. But even mostly taskfile/BMDMA PCI IDE complying
+ controllers may have implementation specific requirements and
+ mechanism to reset themselves. This must be addressed by
+ specific drivers.
+
+
+
+ OTOH, ATA/ATAPI standard describes in detail ways to reset
+ ATA/ATAPI devices.
+
+
+
+
+ PATA hardware reset
+
+
+ This is hardware initiated device reset signalled with
+ asserted PATA RESET- signal. There is no standard way to
+ initiate hardware reset from software although some
+ hardware provides registers that allow driver to directly
+ tweak the RESET- signal.
+
+
+
+
+ Software reset
+
+
+ This is achieved by turning CONTROL SRST bit on for at
+ least 5us. Both PATA and SATA support it but, in case of
+ SATA, this may require controller-specific support as the
+ second Register FIS to clear SRST should be transmitted
+ while BSY bit is still set. Note that on PATA, this resets
+ both master and slave devices on a channel.
+
+
+
+
+ EXECUTE DEVICE DIAGNOSTIC command
+
+
+ Although ATA/ATAPI standard doesn't describe exactly, EDD
+ implies some level of resetting, possibly similar level
+ with software reset. Host-side EDD protocol can be handled
+ with normal command processing and most SATA controllers
+ should be able to handle EDD's just like other commands.
+ As in software reset, EDD affects both devices on a PATA
+ bus.
+
+
+ Although EDD does reset devices, this doesn't suit error
+ handling as EDD cannot be issued while BSY is set and it's
+ unclear how it will act when device is in unknown/weird
+ state.
+
+
+
+
+ ATAPI DEVICE RESET command
+
+
+ This is very similar to software reset except that reset
+ can be restricted to the selected device without affecting
+ the other device sharing the cable.
+
+
+
+
+ SATA phy reset
+
+
+ This is the preferred way of resetting a SATA device. In
+ effect, it's identical to PATA hardware reset. Note that
+ this can be done with the standard SCR Control register.
+ As such, it's usually easier to implement than software
+ reset.
+
+
+
+
+
+
+
+ One more thing to consider when resetting devices is that
+ resetting clears certain configuration parameters and they
+ need to be set to their previous or newly adjusted values
+ after reset.
+
+
+
+ Parameters affected are.

+PEC Support
+-----------
+
+The ADM1032 is the only chip of the family which supports PEC. It does
+not support PEC on all transactions though, so some care must be taken.
+
+When reading a register value, the PEC byte is computed and sent by the
+ADM1032 chip. However, in the case of a combined transaction (SMBus Read
+Byte), the ADM1032 computes the CRC value over only the second half of
+the message rather than its entirety, because it thinks the first half
+of the message belongs to a different transaction. As a result, the CRC
+value differs from what the SMBus master expects, and all reads fail.
+
+For this reason, the lm90 driver will enable PEC for the ADM1032 only if
+the bus supports the SMBus Send Byte and Receive Byte transaction types.
+These transactions will be used to read register values, instead of
+SMBus Read Byte, and PEC will work properly.
+
+Additionally, the ADM1032 doesn't support SMBus Send Byte with PEC.
+Instead, it will try to write the PEC value to the register (because the
+SMBus Send Byte transaction with PEC is similar to a Write Byte transaction
+without PEC), which is not what we want. Thus, PEC is explicitely disabled
+on SMBus Send Byte transactions in the lm90 driver.
+
+PEC on byte data transactions represents a significant increase in bandwidth
+usage (+33% for writes, +25% for reads) in normal conditions. With the need
+to use two SMBus transaction for reads, this overhead jumps to +50%. Worse,
+two transactions will typically mean twice as much delay waiting for
+transaction completion, effectively doubling the register cache refresh time.
+I guess reliability comes at a price, but it's quite expensive this time.
+
+So, as not everyone might enjoy the slowdown, PEC can be disabled through
+sysfs. Just write 0 to the "pec" file and PEC will be disabled. Write 1
+to that file to enable PEC again.

+===================

+Supported chips:
+ * Xicor X1205 RTC
+ Prefix: 'x1205'
+ Addresses scanned: none
+ Datasheet: http://www.intersil.com/cda/deviceinfo/0,1477,X1205,00.html
+
+Authors:

+
+Description
+-----------
+
+This module aims to provide complete access to the Xicor X1205 RTC.
+Recently Xicor has merged with Intersil, but the chip is
+still sold under the Xicor brand.
+
+This chip is located at address 0x6f and uses a 2-byte register addressing.
+Two bytes need to be written to read a single register, while most
+other chips just require one and take the second one as the data
+to be written. To prevent corrupting unknown chips, the user must
+explicitely set the probe parameter.
+
+example:
+
+modprobe x1205 probe=0,0x6f
+
+The module supports one more option, hctosys, which is used to set the
+software clock from the x1205. On systems where the x1205 is the
+only hardware rtc, this parameter could be used to achieve a correct
+date/time earlier in the system boot sequence.
+
+example:
+
+modprobe x1205 probe=0,0x6f hctosys=1

+
+FILES, CONFIGS AND COMPATABILITY
+--------------------------------
+
+Two files are introduced:
+
+ a) 'include/asm-mips/mach-au1x00/au1xxx_ide.h'
+ containes : struct _auide_hwif
+ struct drive_list_entry dma_white_list
+ struct drive_list_entry dma_black_list
+ timing parameters for PIO mode 0/1/2/3/4
+ timing parameters for MWDMA 0/1/2
+
+ b) 'drivers/ide/mips/au1xxx-ide.c'
+ contains the functionality of the AU1XXX IDE driver
+
+Four configs variables are introduced:
+
+ CONFIG_BLK_DEV_IDE_AU1XXX_PIO_DBDMA - enable the PIO+DBDMA mode
+ CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA - enable the MWDMA mode
+ CONFIG_BLK_DEV_IDE_AU1XXX_BURSTABLE_ON - set Burstable FIFO in DBDMA
+ controler
+ CONFIG_BLK_DEV_IDE_AU1XXX_SEQTS_PER_RQ - maximum transfer size
+ per descriptor
+
+If MWDMA is enabled and the connected hard disc is not on the white list, the
+kernel switches to a "safe mwdma mode" at boot time. In this mode the IDE
+performance is substantial slower then in full speed mwdma. In this case
+please add your hard disc to the white list (follow instruction from 'ADD NEW
+HARD DISC TO WHITE OR BLACK LIST' section).
+
+
+SUPPORTED IDE MODES
+-------------------
+
+The AU1XXX IDE driver supported all PIO modes - PIO mode 0/1/2/3/4 - and all
+MWDMA modes - MWDMA 0/1/2 -. There is no support for SWDMA and UDMA mode.
+
+To change the PIO mode use the program hdparm with option -p, e.g.
+'hdparm -p0 [device]' for PIO mode 0. To enable the MWDMA mode use the option
+-X, e.g. 'hdparm -X32 [device]' for MWDMA mode 0.
+
+
+PERFORMANCE CONFIGURATIONS
+--------------------------
+
+If the used system doesn't need USB support enable the following kernel configs:
+
+CONFIG_IDE=y
+CONFIG_BLK_DEV_IDE=y
+CONFIG_IDE_GENERIC=y
+CONFIG_BLK_DEV_IDEPCI=y
+CONFIG_BLK_DEV_GENERIC=y

+CONFIG_BLK_DEV_IDE_AU1XXX_SEQTS_PER_RQ=128
+CONFIG_BLK_DEV_IDEDMA=y
+CONFIG_IDEDMA_AUTO=y
+
+If the used system need the USB support enable the following kernel configs for
+high IDE to USB throughput.
+
+CONFIG_BLK_DEV_IDEDISK=y
+CONFIG_IDE_GENERIC=y
+CONFIG_BLK_DEV_IDEPCI=y
+CONFIG_BLK_DEV_GENERIC=y

+CONFIG_BLK_DEV_IDE_AU1XXX_SEQTS_PER_RQ=128
+CONFIG_BLK_DEV_IDEDMA=y
+CONFIG_IDEDMA_AUTO=y
+
+
+ADD NEW HARD DISC TO WHITE OR BLACK LIST
+----------------------------------------
+
+Step 1 : detect the model name of your hard disc
+
+ a) connect your hard disc to the AU1XXX
+
+ b) boot your kernel and get the hard disc model.
+
+ Example boot log:
+
+ --snipped--
+ Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
+ ide: Assuming 50MHz system bus speed for PIO modes; override with idebus=xx
+ Au1xxx IDE(builtin) configured for MWDMA2
+ Probing IDE interface ide0...
+ hda: Maxtor 6E040L0, ATA DISK drive
+ ide0 at 0xac800000-0xac800007,0xac8001c0 on irq 64
+ hda: max request size: 64KiB
+ hda: 80293248 sectors (41110 MB) w/2048KiB Cache, CHS=65535/16/63, (U)DMA
+ --snipped--
+
+ In this example 'Maxtor 6E040L0'.
+
+Step 2 : edit 'include/asm-mips/mach-au1x00/au1xxx_ide.h'
+
+ Add your hard disc to the dma_white_list or dma_black_list structur.
+
+Step 3 : Recompile the kernel
+
+ Enable MWDMA support in the kernel configuration. Recompile the kernel and
+ reboot.
+
+Step 4 : Tests
+
+ If you have add a hard disc to the white list, please run some stress tests
+ for verification.
+
+
+ACKNOWLEDGMENTS

+ * the reserved page
*
- * SAL provides one page per partition of reserved memory. When SAL
- * initialization is complete, SAL_signature, SAL_version, partid,
- * part_nasids, and mach_nasids are set.
+ * SAL reserves one page of memory per partition for XPC. Though a full page
+ * in length (16384 bytes), its starting address is not page aligned, but it
+ * is cacheline aligned. The reserved page consists of the following:
+ *
+ * reserved page header
+ *
+ * The first cacheline of the reserved page contains the header
+ * (struct xpc_rsvd_page). Before SAL initialization has completed,
+ * SAL has set up the following fields of the reserved page header:
+ * SAL_signature, SAL_version, partid, and nasids_size. The other
+ * fields are set up by XPC. (xpc_rsvd_page points to the local
+ * partition's reserved page.)
+ *
+ * part_nasids mask
+ * mach_nasids mask
+ *
+ * SAL also sets up two bitmaps (or masks), one that reflects the actual
+ * nasids in this partition (part_nasids), and the other that reflects
+ * the actual nasids in the entire machine (mach_nasids). We're only
+ * interested in the even numbered nasids (which contain the processors
+ * and/or memory), so we only need half as many bits to represent the
+ * nasids. The part_nasids mask is located starting at the first cacheline
+ * following the reserved page header. The mach_nasids mask follows right
+ * after the part_nasids mask. The size in bytes of each mask is reflected
+ * by the reserved page header field 'nasids_size'. (Local partition's
+ * mask pointers are xpc_part_nasids and xpc_mach_nasids.)
+ *
+ * vars
+ * vars part
+ *
+ * Immediately following the mach_nasids mask are the XPC variables
+ * required by other partitions. First are those that are generic to all
+ * partitions (vars), followed on the next available cacheline by those
+ * which are partition specific (vars part). These are setup by XPC.
+ * (Local partition's vars pointers are xpc_vars and xpc_vars_part.)
*
* Note: Until vars_pa is set, the partition XPC code has not been initialized.

- ---help---
- Some Atari 68k machines (including the 520STF and 1020STE) divide
- their addressable memory into ST and TT sections. The TT section
- (up to 512MB) is the main memory; the ST section (up to 4MB) is
- accessible to the built-in graphics board, runs slower, and is
- present mainly for backward compatibility with older machines.
-
- This enables support for using (parts of) ST-RAM as swap space,
- instead of as normal system memory. This can first enhance system
- performance if you have lots of alternate RAM (compared to the size
- of ST-RAM), because executable code always will reside in faster
- memory. ST-RAM will remain as ultra-fast swap space. On the other
- hand, it allows much improved dynamic allocations of ST-RAM buffers
- for device driver modules (e.g. floppy, ACSI, SLM printer, DMA
- sound). The probability that such allocations at module load time
- fail is drastically reduced.

- * New Nov 1997: Use ST-RAM as swap space!
- *
- * In the past, there were often problems with modules that require ST-RAM
- * buffers. Such drivers have to use __get_dma_pages(), which unfortunately
- * often isn't very successful in allocating more than 1 page :-( [1] The net
- * result was that most of the time you couldn't insmod such modules (ataflop,
- * ACSI, SCSI on Falcon, Atari internal framebuffer, not to speak of acsi_slm,
- * which needs a 1 MB buffer... :-).
- *
- * To overcome this limitation, ST-RAM can now be turned into a very
- * high-speed swap space. If a request for an ST-RAM buffer comes, the kernel
- * now tries to unswap some pages on that swap device to make some free (and
- * contiguous) space. This works much better in comparison to
- * __get_dma_pages(), since used swap pages can be selectively freed by either
- * moving them to somewhere else in swap space, or by reading them back into
- * system memory. Ok, there operation of unswapping isn't really cheap (for
- * each page, one has to go through the page tables of all processes), but it
- * doesn't happen that often (only when allocation ST-RAM, i.e. when loading a
- * module that needs ST-RAM). But it at least makes it possible to load such
- * modules!
- *
- * It could also be that overall system performance increases a bit due to
- * ST-RAM swapping, since slow ST-RAM isn't used anymore for holding data or
- * executing code in. It's then just a (very fast, compared to disk) back
- * storage for not-so-often needed data. (But this effect must be compared
- * with the loss of total memory...) Don't know if the effect is already
- * visible on a TT, where the speed difference between ST- and TT-RAM isn't
- * that dramatic, but it should on machines where TT-RAM is really much faster
- * (e.g. Afterburner).
- *
- * [1]: __get_free_pages() does a fine job if you only want one page, but if
- * you want more (contiguous) pages, it can give you such a block only if
- * there's already a free one. The algorithm can't try to free buffers or swap
- * out something in order to make more free space, since all that page-freeing
- * mechanisms work "target-less", i.e. they just free something, but not in a
- * specific place. I.e., __get_free_pages() can't do anything to free
- * *adjacent* pages :-( This situation becomes even worse for DMA memory,
- * since the freeing algorithms are also blind to DMA capability of pages.
