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.

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. + + + + + + + CHS set up with INITIALIZE DEVICE PARAMETERS (seldomly used) + + + + + + Parameters set with SET FEATURES including transfer mode setting + + + + + + Block count set with SET MULTIPLE MODE + + + + + + Other parameters (SET MAX, MEDIA LOCK...) + + + + + + + ATA/ATAPI standard specifies that some parameters must be + maintained across hardware or software reset, but doesn't + strictly specify all of them. Always reconfiguring needed + parameters after reset is required for robustness. Note that + this also applies when resuming from deep sleep (power-off). + + + + Also, ATA/ATAPI standard requires that IDENTIFY DEVICE / + IDENTIFY PACKET DEVICE is issued after any configuration + parameter is updated or a hardware reset and the result used + for further operation. OS driver is required to implement + revalidation mechanism to support this. + + + + + + Reconfigure transport + + + For both PATA and SATA, a lot of corners are cut for cheap + connectors, cables or controllers and it's quite common to see + high transmission error rate. This can be mitigated by + lowering transmission speed. + + + + The following is a possible scheme Jeff Garzik suggested. + + +
+ + If more than $N (3?) transmission errors happen in 15 minutes, + + + + + if SATA, decrease SATA PHY speed. if speed cannot be decreased, + + + + + decrease UDMA xfer speed. if at UDMA0, switch to PIO4, + + + + + decrease PIO xfer speed. if at PIO3, complain, but continue + + + +

No drivers take - * advantage of this yet. - * Removed the #ifdef MODULE, now there is no module specific code. - * Cleaned up a few comments in usb-serial.h that were wrong (thanks again - * to Miles Lott). - * Small fix to get_free_serial. - * - * (02/14/2000) gkh - * Removed the Belkin and Peracom functionality from the driver due to - * the lack of support from the vendor, and me not wanting people to - * accidenatly buy the device, expecting it to work with Linux. - * Added read_bulk_callback and write_bulk_callback to the type structure - * for the needs of the FTDI and WhiteHEAT driver. - * Changed all reverences to FTDI to FTDI_SIO at the request of Bill - * Ryder. - * Changed the output urb size back to the max endpoint size to make - * the ftdi_sio driver have it easier, and due to the fact that it didn't - * really increase the speed any. - * - * (02/11/2000) gkh - * Added VISOR_FUNCTION_CONSOLE to the visor startup function.

Also made them always show up in the log file. - * - * (01/25/2000) gkh - * Added initial framework for FTDI serial converter so that Bill Ryder - * has a place to put his code. - * Added the vendor specific info from Handspring. Now we can print out - * informational debug messages as well as understand what is happening. - * - * (01/23/2000) gkh - * Fixed problem of crash when trying to open a port that didn't have a - * device assigned to it. Made the minor node finding a little smarter, - * now it looks to find a continuous space for the new device. - * - * (01/21/2000) gkh - * Fixed bug in visor_startup with patch from Miles Lott (milos@insync.net) - * Fixed get_serial_by_minor which was all messed up for multi port - * devices. Fixed multi port problem for generic devices. Now the number - * of ports is determined by the number of bulk out endpoints for the - * generic device. - * - * (01/19/2000) gkh - * Removed lots of cruft that was around from the old (pre urb) driver - * interface. - * Made the serial_table dynamic. This should save lots of memory when - * the number of minor nodes goes up to 256. - * Added initial support for devices that have more than one port. - * Added more debugging comments for the Visor, and added a needed - * set_configuration call. - * - * (01/17/2000) gkh - * Fixed the WhiteHEAT firmware (my processing tool had a bug) - * and added new debug loader firmware for it. - * Removed the put_char function as it isn't really needed. - * Added visor startup commands as found by the Win98 dump. - * - * (01/13/2000) gkh - * Fixed the vendor id for the generic driver to the one I meant it to be. - * - * (01/12/2000) gkh - * Forget the version numbering...that's pretty useless... - * Made the driver able to be compiled so that the user can select which - * converter they want to use. This allows people who only want the Visor - * support to not pay the memory size price of the WhiteHEAT. - * Fixed bug where the generic driver (idVendor=0000 and idProduct=0000) - * grabbed the root hub. Not good. - * - * version 0.4.0 (01/10/2000) gkh - * Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT - * device. Added startup function to allow firmware to be downloaded to - * a device if it needs to be. - * Added firmware download logic to the WhiteHEAT device. - * Started to add #defines to split up the different drivers for potential - * configuration option. - * - * version 0.3.1 (12/30/99) gkh - * Fixed problems with urb for bulk out. - * Added initial support for multiple sets of endpoints. This enables - * the Handspring Visor to be attached successfully. Only the first - * bulk in / bulk out endpoint pair is being used right now. - * - * version 0.3.0 (12/27/99) gkh - * Added initial support for the Handspring Visor based on a patch from - * Miles Lott (milos@sneety.insync.net) - * Cleaned up the code a bunch and converted over to using urbs only. - * - * version 0.2.3 (12/21/99) gkh - * Added initial support for the Connect Tech WhiteHEAT converter. - * Incremented the number of ports in expectation of getting the - * WhiteHEAT to work properly (4 ports per connection). - * Added notification on insertion and removal of what port the - * device is/was connected to (and what kind of device it was). - * - * version 0.2.2 (12/16/99) gkh - * Changed major number to the new allocated number. We're legal now! - * - * version 0.2.1 (12/14/99) gkh - * Fixed bug that happens when device node is opened when there isn't a - * device attached to it. Thanks to marek@webdesign.no for noticing this. - * - * version 0.2.0 (11/10/99) gkh - * Split up internals to make it easier to add different types of serial - * converters to the code. - * Added a "generic" driver that gets it's vendor and product id - * from when the module is loaded. Thanks to David E. Nelson (dnelson@jump.net) - * for the idea and sample code (from the usb scanner driver.) - * Cleared up any licensing questions by releasing it under the GNU GPL. - * - * version 0.1.2 (10/25/99) gkh - * Fixed bug in detecting device. - * - * version 0.1.1 (10/05/99) gkh - * Changed the major number to not conflict with anything else. - * - * version 0.1 (09/28/99) gkh - * Can recognize the two different devices and start up a read from - * device when asked to. Writes also work. No control signals yet, this - * all is vendor specific data (i.e. no spec), also no control for - * different baud rates or other bit settings. - * Currently we are using the same devid as the acm driver.
