This makes their - * adaptation to platforms like the Mac (Some of which use NCR5380's) - * more difficult than it has to be. - * - * Also, many of the SCSI drivers were written before the command queuing - * routines were implemented, meaning their implementations of queued - * commands were hacked on rather than designed in from the start. - * - * When I designed the Linux SCSI drivers I figured that - * while having two different SCSI boards in a system might be useful - * for debugging things, two of the same type wouldn't be used. - * Well, I was wrong and a number of users have mailed me about running - * multiple high-performance SCSI boards in a server. - * - * Finally, when I get questions from users, I have no idea what - * revision of my driver they are running. - * - * This driver attempts to address these problems : - * This is a generic 5380 driver. To use it on a different platform, - * one simply writes appropriate system specific macros (ie, data - * transfer - some PC's will use the I/O bus, 68K's must use - * memory mapped) and drops this file in their 'C' wrapper. - * - * As far as command queueing, two queues are maintained for - * each 5380 in the system - commands that haven't been issued yet, - * and commands that are currently executing. This means that an - * unlimited number of commands may be queued, letting - * more commands propagate from the higher driver levels giving higher - * throughput. Note that both I_T_L and I_T_L_Q nexuses are supported, - * allowing multiple commands to propagate all the way to a SCSI-II device - * while a command is already executing. - * - * To solve the multiple-boards-in-the-same-system problem, - * there is a separate instance structure for each instance - * of a 5380 in the system. So, multiple NCR5380 drivers will - * be able to coexist with appropriate changes to the high level - * SCSI code. - * - * A NCR5380_PUBLIC_REVISION macro is provided, with the release - * number (updated for each public release) printed by the - * NCR5380_print_options command, which should be called from the - * wrapper detect function, so that I know what release of the driver - * users are using. - * - * Issues specific to the NCR5380 : - * - * When used in a PIO or pseudo-dma mode, the NCR5380 is a braindead - * piece of hardware that requires you to sit in a loop polling for - * the REQ signal as long as you are connected. Some devices are - * brain dead (ie, many TEXEL CD ROM drives) and won't disconnect - * while doing long seek operations. - * - * The workaround for this is to keep track of devices that have - * disconnected. If the device hasn't disconnected, for commands that - * should disconnect, we do something like - * - * while (!REQ is asserted) { sleep for N usecs; poll for M usecs } - * - * Some tweaking of N and M needs to be done. An algorithm based - * on "time to data" would give the best results as long as short time - * to datas (ie, on the same track) were considered, however these - * broken devices are the exception rather than the rule and I'd rather - * spend my time optimizing for the normal case. - * - * Architecture : - * - * At the heart of the design is a coroutine, NCR5380_main, - * which is started when not running by the interrupt handler, - * timer, and queue command function. It attempts to establish - * I_T_L or I_T_L_Q nexuses by removing the commands from the - * issue queue and calling NCR5380_select() if a nexus - * is not established. - * - * Once a nexus is established, the NCR5380_information_transfer() - * phase goes through the various phases as instructed by the target. - * if the target goes into MSG IN and sends a DISCONNECT message, - * the command structure is placed into the per instance disconnected - * queue, and NCR5380_main tries to find more work. If USLEEP - * was defined, and the target is idle for too long, the system - * will try to sleep. - * - * If a command has disconnected, eventually an interrupt will trigger, - * calling NCR5380_intr() which will in turn call NCR5380_reselect - * to reestablish a nexus. This will run main if necessary. - * - * On command termination, the done function will be called as - * appropriate. - * - * SCSI pointers are maintained in the SCp field of SCSI command - * structures, being initialized after the command is connected - * in NCR5380_select, and set as appropriate in NCR5380_information_transfer. - * Note that in violation of the standard, an implicit SAVE POINTERS operation - * is done, since some BROKEN disks fail to issue an explicit SAVE POINTERS. - */ - -/* - * Using this file : - * This file a skeleton Linux SCSI driver for the NCR 5380 series - * of chips.

Some notes: - * - * Using consecutive numbers for the tags is no good idea in my eyes. There - * could be wrong re-usings if the counter (8 bit!) wraps and some early - * command has been preempted for a long time. My solution: a bitfield for - * remembering used tags. - * - * There's also the problem that each target has a certain queue size, but we - * cannot know it in advance :-( We just see a QUEUE_FULL status being - * returned. So, in this case, the driver internal queue size assumption is - * reduced to the number of active tags if QUEUE_FULL is returned by the - * target. The command is returned to the mid-level, but with status changed - * to BUSY, since --as I've seen-- the mid-level can't handle QUEUE_FULL - * correctly. - * - * We're also not allowed running tagged commands as long as an untagged - * command is active. And REQUEST SENSE commands after a contingent allegiance - * condition _must_ be untagged. To keep track whether an untagged command has - * been issued, the host->busy array is still employed, as it is without - * support for tagged queuing. - * - * One could suspect that there are possible race conditions between - * is_lun_busy(), cmd_get_tag() and cmd_free_tag(). But I think this isn't the - * case: is_lun_busy() and cmd_get_tag() are both called from NCR5380_main(), - * which already guaranteed to be running at most once. It is also the only - * place where tags/LUNs are allocated. So no other allocation can slip - * between that pair, there could only happen a reselection, which can free a - * tag, but that doesn't hurt.
