Small initialization fixes: o 'point-to-point preferred, else loop' is not a safe connection mode setting for ISP2200 boards. Use 'loop preferred, else point-to-point.' o Add modules parameter to enable ZIO -- Support mode 5 only. o No point in doing a PRLI (process login) to the SNS port. o Fix problem where the driver would incorrectly skip ports with the same domain and area of the HBA.

Problem reported/corrected by Michael Reed [mdr@sgi.com]: We have a 2312 that puts the 8.00.00b12-k qla2xxx driver into an infinite loop with a solid interrupt, 0x8008, hcsr = 0x7430, risc status register 0x40008110, immediately after enabling parity on the board. It looks as though the early out test in qla_isr.c:qla2x00_intr_handler() against stat is broken. HSR_RISC_PAUSED is set. Also, there's a stale mailbox completion flagged (stat&0xff) which will short circuit the default case in the switch if it got that far. Signed-off-by:

Problem reported/corrected by Tony Battersby [tonyb@cybernetics.com]: o The qla2xxx driver calculates data transfer residuals for some but not all circumstances. The patch below adds data transfer residual calculations for the remaining cases. o Interrogate the proper cmnd[] array when determining the transfer direction. Signed-off-by: -

While reviewing tmscsim, I noticed something, I didn't quite like / understand. The driver takes the host_lock (with irqsave) at the entry to the ISR, and releases it at the exit. And inside the ISR there are potentially long busy-waits... Like int ctr = 6000000; /* only try for about a second */ while( --ctr && !((dstate = DC390_read8 (DMA_Status)) & DMA_XFER_DONE) && pSRB->SGToBeXferLen ); The attached patch is attempting to fix those places. Not sure if this is a proper fix though. In my understanding, after looking through the code, the host_lock is used to protect host-specific data and host-registers. The ->queuecommand is already called with it help, so, one just, basically, have to protect other contexts - interrupt, timer,... So, looks mostly right. Signed-off-by: -

Also fixed some __init / __devinit and __exit / __devexit attributes.

From: Matthew Wilcox <willy@debian.org> - remove all of the PCI chips (8xx series) leaving only 720 - pull out stand alone initialisation code (driver becomes a chip only driver for NCR Q720 and Zalon) - remove most vestiges of PCI support (chip driver should be bus neutral) - tidy up typedefs - remove simulated intfly (may need putting back for 770) Signed-off-by: -

Some SCSI-IDE cdrom drives take up to 15 seconds to respond following an abort being issued to them. This patch changes ipr to only send a cancel all to a device as part of request sense processing when the device is running tagged command queueing. Signed-off-by: -
Brian King authored
The following patch fixes a hang that occurs when an abort is issued by the midlayer. The hang is the result of overriding a field in the union of the ipr_cmd struct. It is fixed by moving this pointer outside of the union, since it is not mutually exclusive with the other fields in the union. Signed-off-by: -

The BLIST_REPORTLUN2 blacklist item has exactly the behavior that the MYLEX DACARMRB (and SGI TP9100, which is really a 2Gb upgrade to the DACARMRB) need. These devices use a PQ of 1 instead of 3 for unconfigured luns, which means that every RAID has 32 luns, many or most of which are just phantoms. However, it does support Report Luns, and it returns the correct data. Signed-off-by: -

The object of this infrastructure is to give HBAs early warning that error handling is about to happen and also provide them with the opportunity to do something about it. It introduces the extra template callback: eh_timed_out() which scsi_times_out() will call if it is populated to notify the LLD that an outstanding command took a timeout. There are three possible returns: EH_HANDLED: I've fixed the problem, please complete the command for me (as soon as the timer fires, scsi_done will do nothing, so the timer itself will call a special version of scsi_done that doesn't check the timer). EH_NOT_HANDLED: Invoke error recovery as normal EH_RESET_TIMER: The command will complete, reset the timer to its original value and start it ticking again. Signed-off-by: -

I've been going through Mark's changes with a fine toothcomb and this merges most of them. Its tested on 64bit SMP hardware and seems to be fine. There are a couple of Mark's changes I've left out for now but there isnt really an easy way to break down the changes further. This fixes a whole host of problems including random hangs under high load Signed-off-by:

This is a fix for when we encounter an alias during insert. When that happens we move the request to dispatch, but it may happen that this request is also the ->last_merge hint. So we may attempt to merge with this later, when it's either in progress or already freed. Rearrange the logic a bit so we clear the merge hint there as well. It looks more complex than it is, the only real code change is the addition of a cfq_remove_merge_hints() in cfq_dispatch_sort(). Signed-off-by:Linus Torvalds <torvalds@osdl.org>

This cset adds the code to handle the hardware vector floating point unit found on some ARM926 and later CPUs. The hardware provides an implementation for the common cases, and bounces exceptions for other cases, which have to be handled in software, and signalling SIGFPE as appropriate.
