* [SCSI] aacraid: superfluous adapter reset for IBM 8 series ServeRAID controllersSalyzyn, Mark2007-05-061-1/+1
| | | | | | | | | | | | The kexec patch introduced a superfluous (and otherwise inert) reset of some adapters. The register can have a hardware default value that has zeros for the undefined interrupts. This patch refines the test of the interrupt enable register to focus on only the interrupts that affect the driver in order to detect if an incomplete shutdown of the Adapter had occurred (kdump).

| | | | | | | | | | | | | cpu_to_le32 endianness conversions in tmscsim.c, followed by arithmetic operations don't look correct. Besides, {in,out}[wl] already perform the necessary conversions. Further, bus addresses of request buffers are guaranteed to be (mapped) under 4G by current scsi- and block-layer defaults. This could be explicitly enforced by using blk_queue_bounce_limit(), which, however, doesn't seem to be the common practice among SCSI drivers. Signed-off-by: G.

* [SCSI] ipr: Better handle adapter boot time errorsBrian King2007-05-061-1/+6
| | | | | | | | | | | | If an ipr adapter encounters an adapter error requiring an adapter reset to recover from prior to driver load time, the error will be ignored and recovery will not happen until the initial timeout occurs waiting for the firmware to come ready, which means a five minute timeout. Fix is to read the interrupt register before clearing any of the interrupts at probe time.

* [SCSI] fc_transport: make all rports wait dev_loss_tmo before removing themJames Smart2007-05-061-61/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | Per the comment in the change - it's not always prudent to immediately remove the rport upon first notice of a disconnect. Make all rports wait dev_loss_tmo before being deleted (and each could have a separate dev_loss_tmo value). The original post was: http://marc.info/?l=linux-scsi&m=117392196006703&w=2 The repost contains the following changes: - Bug fix in fc_starget_delete(). Dev_loss_tmo_callbk() was called prior to tearing down the target. The callback is to be the last thing called, as it tells the LLDD that the rport is completely finished and can be torn down. Rework so that terminate_rport_io() is called to terminate the outstanding io. Isolated work so it's is simply "starget" work. - Fix holes in original patch. There were code paths that did not expect the dev_loss_tmo timer to be running for the non-fcp rports. - Bug Fix: the transport wasn't protecting against a LLDD calling fc_remote_port_delete() back-to-back. Thus, the dev_loss_tmo timer could be restarted such that it fires after the rport had been deleted. Validate rport state before starting the timer.

* [SCSI] use sysfs configured timeout for EH Start Unit timeoutBrian King2007-05-061-2/+1
| | | | | | | | | | | | | | | Use the sysfs configurable timeout when issuing a START_UNIT command from the scsi error handler. This is needed for devices which take longer than thirty seconds to respond to the start unit. The problem was observed when sending a start unit to a disk array device in an ipr RAID adapter, which results in the adapter firmware sending potentially multiple commands to physical devices as a result of this command, which ended up timing out sometimes.

The modalias format is like this: scsi:type-0x04 (for TYPE_WORM, handled by sr.c now). Several comments. o This hexadecimal type value is because all TYPE_XXX constants in include/scsi/scsi.h are given in hex, but __stringify() will not convert them to decimal (so it will NOT be scsi:type-4). Since it does not really matter in which format it is, while both modalias in module and modalias attribute match each other, I descided to go for that 0x%02x format (and added a comment in include/scsi/scsi.h to keep them that way), instead of changing them all to decimal. o There was no .uevent routine for SCSI bus. It might be a good idea to add some more ueven environment variables in there. o osst.c driver handles tapes too, like st.c, but only SOME tapes. With this setup, hotplug scripts (or whatever is used by the user) will try to load both st and osst modules for all SCSI tapes found, because both modules have scsi:type-0x01 alias). It is not harmful, but one extra module is no good either. It is possible to solve this, by exporting more info in modalias attribute, including vendor and device identification strings, so that modalias becomes something like scsi:type-0x12:vendor-Adaptec LTD:device-OnStream Tape Drive and having that, match for all 3 attributes, not only device type. But oh well, vendor and device strings may be large, and they do contain spaces and whatnot. So I left them for now, awaiting for comments first.

| * [SCSI] sg: cap reserved_size values at max_sectorsAlan Stern2007-04-171-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as857) modifies the SG_GET_RESERVED_SIZE and SG_SET_RESERVED_SIZE ioctls in the sg driver, capping the values at the device's request_queue's max_sectors value. This will permit cdrecord to obtain a legal value for the maximum transfer length, fixing Bugzilla #7026. The patch also caps the initial reserved_size value. There's no reason to have a reserved buffer larger than max_sectors, since it would be impossible to use the extra space. The corresponding ioctls in the block layer are modified similarly, and the initial value for the reserved_size is set as large as possible. This will effectively make it default to max_sectors. Note that the actual value is meaningless anyway, since block devices don't have a reserved buffer. Finally, the BLKSECTGET ioctl is added to sg, so that there will be a uniform way for users to determine the actual max_sectors value for any raw SCSI transport.
