If you set the bit immediately, you get into the situation where the transport parameters report something as being set even if the drive cannot support it. I patched the driver to do it this way and also corrected a panic in the proc routines.

This reduced the PCI traffic in the driver to submit a command to the queue to near zero allowing a significant number of commands to be turned around with no need to block for the PCI bridge to flush the notify request to the adapter. Interrupt mitigation has always been present in the driver; it was turned off because of a bug that prevented one from realizing the usefulness of the feature. This bug is fixed in this patch.

The timeout is there to clean up should the management application die and fail to poll for updated AIF event packets. Moving the timer update from the ioctl code that delivers an AIF to the polling registrant to the bottom of the ioctl means the timeout is reset with any management application polling activity regardless if an AIF is delivered or not removing the erroneous timeout cleanups.

Brian King has acknowledged that it fixes the problems he has seen. Seems mature enough for inclusion into 2.6.14 (or later)? Nate's explanation of the changes: I've attached patches against 2.6.13rc2. These are basically identical to my earlier patches, as I found that all issues I'd seen in earlier kernels still existed in this kernel. To summarize, the changes are: (more details in my original email) - add a kref to the scsi_tape structure, and associate reference counting stuff - set sr_request->end_io = blk_end_sync_rq so we get notified when an IO is rejected when the device goes away - check rq_status when IOs complete, else we don't know that IOs rejected for a dead device in fact did not complete - change last_SRpnt so it's set before an async IO is issued (in case st_sleep_done is bypassed) - fix a bogus use of last_SRpnt in st_chk_result Signed-off-by: Nate Dailey Signed-off-by: Kai Makisara Signed-off-by: James Bottomley diff --git a/drivers/scsi/st.c b/drivers/scsi/st.c index 0291a8f..47a5698 100644 --- a/drivers/scsi/st.c +++ b/drivers/scsi/st.c @@ -17,7 +17,7 @@ Last modified: 18-JAN-1998 Richard Gooch Devfs support */ -static char *verstr = "20050501"; +static char *verstr = "20050802"; #include @@ -219,6 +219,12 @@ static int switch_partition(struct scsi_tape *); static int st_int_ioctl(struct scsi_tape *, unsigned int, unsigned long); +static void scsi_tape_release(struct kref *); + +#define to_scsi_tape(obj) container_of(obj, struct scsi_tape, kref) + +static DECLARE_MUTEX(st_ref_sem); + #include "osst_detect.h" #ifndef SIGS_FROM_OSST @@ -230,6 +236,46 @@ static int st_int_ioctl(struct scsi_tape *, unsigned int, unsigned long); {"OnStream", "FW-", "", "osst"} #endif +static struct scsi_tape *scsi_tape_get(int dev) +{ + struct scsi_tape *STp = NULL; + + down(&st_ref_sem); + write_lock(&st_dev_arr_lock); + + if (dev < st_dev_max && scsi_tapes != NULL) + STp = scsi_tapes[dev]; + if (!STp) goto out; + + kref_get(&STp->kref); + + if (!STp->device) + goto out_put; + + if (scsi_device_get(STp->device)) + goto out_put; + + goto out; + +out_put: + kref_put(&STp->kref, scsi_tape_release); + STp = NULL; +out: + write_unlock(&st_dev_arr_lock); + up(&st_ref_sem); + return STp; +} + +static void scsi_tape_put(struct scsi_tape *STp) +{ + struct scsi_device *sdev = STp->device; + + down(&st_ref_sem); + kref_put(&STp->kref, scsi_tape_release); + scsi_device_put(sdev); + up(&st_ref_sem); +} + struct st_reject_data { char *vendor; char *model; @@ -311,7 +357,7 @@ static int st_chk_result(struct scsi_tape *STp, struct scsi_request * SRpnt) return 0; cmdstatp = &STp->buffer->cmdstat; - st_analyze_sense(STp->buffer->last_SRpnt, cmdstatp); + st_analyze_sense(SRpnt, cmdstatp); if (cmdstatp->have_sense) scode = STp->buffer->cmdstat.sense_hdr.sense_key; @@ -399,10 +445,10 @@ static void st_sleep_done(struct scsi_cmnd * SCpnt) (STp->buffer)->cmdstat.midlevel_result = SCpnt->result; SCpnt->request->rq_status = RQ_SCSI_DONE; - (STp->buffer)->last_SRpnt = SCpnt->sc_request; DEB( STp->write_pending = 0; ) - complete(SCpnt->request->waiting); + if (SCpnt->request->waiting) + complete(SCpnt->request->waiting); } /* Do the scsi command.

This code will apply a global timeout (of the total number of retries times the per command timer) to a given command. If it is exceeded, the command is completed regardless of its state. The patch also removes the unused field in the command: timeout and timeout_total. This solves the problem of detecting an endless loop in the mid-layer because of BUSY/QUEUE_FULL bouncing, but will not recover the device. In the aic7xxx case, the driver can be recovered by sending a bus reset, so possibly this should be tied into the error handler?
