b74cec98319cdf0854be09126da89ba80d5baa2eCharles Stephens * SiliconImage 3124/3132/3531 sata controller driver
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Few Design notes
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * I. General notes
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Even though the driver is named as si3124, it is actually meant to
b74cec98319cdf0854be09126da89ba80d5baa2eCharles Stephens * work with SiI3124, SiI3132 and SiI3531 controllers.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * The current file si3124.c is the main driver code. The si3124reg.h
b74cec98319cdf0854be09126da89ba80d5baa2eCharles Stephens * holds the register definitions from SiI 3124/3132/3531 data sheets. The
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * si3124var.h holds the driver specific definitions which are not
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * directly derived from data sheets.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * II. Data structures
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * si_ctl_state_t: This holds the driver private information for each
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * controller instance. Each of the sata ports within a single
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * controller are represented by si_port_state_t. The
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * sictl_global_acc_handle and sictl_global_address map the
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * controller-wide global register space and are derived from pci
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * BAR 0. The sictl_port_acc_handle and sictl_port_addr map the
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * per-port register space and are derived from pci BAR 1.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * si_port_state_t: This holds the per port information. The siport_mutex
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * holds the per port mutex. The siport_pending_tags is the bit mask of
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * commands posted to controller. The siport_slot_pkts[] holds the
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * pending sata packets. The siport_port_type holds the device type
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * connected directly to the port while the siport_portmult_state
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * holds the similar information for the devices behind a port
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * multiplier.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * si_prb_t: This contains the PRB being posted to the controller.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * The two SGE entries contained within si_prb_t itself are not
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * really used to hold any scatter gather entries. The scatter gather
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * list is maintained external to PRB and is linked from one
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * of the contained SGEs inside the PRB. For atapi devices, the
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * first contained SGE holds the PACKET and second contained
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * SGE holds the link to an external SGT. For non-atapi devices,
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * the first contained SGE works as link to external SGT while
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * second SGE is blank.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * external SGT tables: The external SGT tables pointed to from
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * within si_prb_t are actually abstracted as si_sgblock_t. Each
81a0678e1c5837dd278edbcc4a617a6c976e7673xun ni - Sun Microsystems - Beijing China * si_sgblock_t contains si_dma_sg_number number of
81a0678e1c5837dd278edbcc4a617a6c976e7673xun ni - Sun Microsystems - Beijing China * SGT tables linked in a chain. Currently this default value of
81a0678e1c5837dd278edbcc4a617a6c976e7673xun ni - Sun Microsystems - Beijing China * SGT tables per block is at 85 as which translates
81a0678e1c5837dd278edbcc4a617a6c976e7673xun ni - Sun Microsystems - Beijing China * to a maximum of 256 dma cookies per single dma transfer.
81a0678e1c5837dd278edbcc4a617a6c976e7673xun ni - Sun Microsystems - Beijing China * This value can be changed through the global var: si_dma_sg_number
81a0678e1c5837dd278edbcc4a617a6c976e7673xun ni - Sun Microsystems - Beijing China * in /etc/system, the maxium is at 21844 as which translates to 65535
81a0678e1c5837dd278edbcc4a617a6c976e7673xun ni - Sun Microsystems - Beijing China * dma cookies per single dma transfer.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * III. Driver operation
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Command Issuing: We use the "indirect method of command issuance". The
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * PRB contains the command [and atapi PACKET] and a link to the
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * external SGT chain. We write the physical address of the PRB into
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * command activation register. There are 31 command slots for
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * each port. After posting a command, we remember the posted slot &
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * the sata packet in siport_pending_tags & siport_slot_pkts[]
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * respectively.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Command completion: On a successful completion, intr_command_complete()
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * receives the control. The slot_status register holds the outstanding
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * commands. Any reading of slot_status register automatically clears
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * the interrupt. By comparing the slot_status register contents with
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * per port siport_pending_tags, we determine which of the previously
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * posted commands have finished.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Timeout handling: Every 5 seconds, the watchdog handler scans thru the
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * pending packets. The satapkt->satapkt_hba_driver_private field is
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * overloaded with the count of watchdog cycles a packet has survived.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * If a packet has not completed within satapkt->satapkt_time, it is
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * failed with error code of SATA_PKT_TIMEOUT. There is one watchdog
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * handler running for each instance of controller.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Error handling: For 3124, whenever any single command has encountered
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * an error, the whole port execution completely stalls; there is no
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * way of canceling or aborting the particular failed command. If
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * the port is connected to a port multiplier, we can however RESUME
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * other non-error devices connected to the port multiplier.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * The only way to recover the failed commands is to either initialize
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * the port or reset the port/device. Both port initialize and reset
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * operations result in discarding any of pending commands on the port.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * All such discarded commands are sent up to framework with PKT_RESET
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * satapkt_reason. The assumption is that framework [and sd] would
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * retry these commands again. The failed command itself however is
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * sent up with PKT_DEV_ERROR.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Here is the implementation strategy based on SiliconImage email
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * regarding how they handle the errors for their Windows driver:
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * a) for DEVICEERROR:
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * If the port is connected to port multiplier, then
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * 1) Resume the port
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * 2) Wait for all the non-failed commands to complete
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * 3) Perform a Port Initialize
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * If the port is not connected to port multiplier, issue
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * a Port Initialize.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * b) for SDBERROR: [SDBERROR means failed command is an NCQ command]
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Handle exactly like DEVICEERROR handling.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * After the Port Initialize done, do a Read Log Extended.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * c) for SENDFISERROR:
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * If the port is connected to port multiplier, then
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * 1) Resume the port
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * 2) Wait for all the non-failed commands to complete
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * 3) Perform a Port Initialize
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * If the port is not connected to port multiplier, issue
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * a Device Reset.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * d) for DATAFISERROR:
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * If the port was executing an NCQ command, issue a Device
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Otherwise, follow the same error recovery as DEVICEERROR.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * e) for any other error, simply issue a Device Reset.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * To synchronize the interactions between various control flows (e.g.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * error recovery, timeout handling, si_poll_timeout, incoming flow
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * from framework etc.), the following precautions are taken care of:
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * a) During mopping_in_progress, no more commands are
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * accepted from the framework.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * b) While draining the port multiplier commands, we should
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * handle the possibility of any of the other waited commands
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * failing (possibly with a different error code)
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Atapi handling: For atapi devices, we use the first SGE within the PRB
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * to fill the scsi cdb while the second SGE points to external SGT.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Queuing: Queue management is achieved external to the driver inside sd.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Based on sata_hba_tran->qdepth and IDENTIFY data, the framework
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * enables or disables the queuing. The qdepth for si3124 is 31
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * commands.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Port Multiplier: Enumeration of port multiplier is handled during the
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * controller initialization and also during the a hotplug operation.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Current logic takes care of situation where a port multiplier
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * is hotplugged into a port which had a cdisk connected previously
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * and vice versa.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * Register poll timeouts: Currently most of poll timeouts on register
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * reads is set to 0.5 seconds except for a value of 10 seconds
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * while reading the device signature. [Such a big timeout values
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * for device signature were found needed during cold reboots
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * for devices behind port multiplier].
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * IV. Known Issues
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * 1) Currently the atapi packet length is hard coded to 12 bytes
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * This is wrong. The framework should determine it just like they
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * determine ad_cdb_len in legacy atapi.c. It should even reject
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * init_pkt() for greater CDB lengths. See atapi.c. Revisit this
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * in 2nd phase of framework project.
66f9d5cb3cc0652e2d9d1366fb950efbe4ca2f24mlf * 2) Do real REQUEST SENSE command instead of faking for ATAPI case.
