Some cards need to pause the sequencer before the SBLKCTL register is touched. This fixes a PCI related oops seen on powerpc macs with this card caused by trying to ascertain the bus signalling before beginning domain validation. Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

For cards that don't support LVD, checking the SBLKCTL register to determine the bus singalling doesn't work. So, check that the card supports LVD first (AHC_ULTRA2) before checking the register. Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

Read the transciever register and display in the host transport properties. I'm still not entirely sure what this does for multiple transciever adapters (like some 160 ones) however, I suspect it displays the transciever state of the switchable bus segment.

The driver is doing a rather stupid mod_timer allegedly to "give request sense more time to complete". This is illegal and pointless, so just eliminate it. Also eliminate all the other uses of struct timer_list in the driver, which are mostly bogus. Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

To transport scsi reset command to device aic7xxx reset handler looks at the driver's pending_list and searches any proper command. However the search condition has been inverted: ahc_match_scb() returns TRUE if a matched command is found. As a result the reset on required devices did not turn out well, a correctly working neighbour device may be surprised by the reset. aic7xxx reset handler reports about the success, but really the original situation is not corrected yet. Signed-off-by: NVasily Averin <vvs@sw.ru> Naturally, there's a corresponding problem in the aic79xx driver, so I've also added the same fix for that.

In these drivers, scsi_remove_host() is called too late, at the point it is called, the driver has already shut down too far to accept any I/O that the shutdown might generate. Any generated I/O actually triggers a panic. Fix this by calling scsi_remove_host() as early as possible and not calling scsi_host_put() until just before we kfree the ahc_softc.

This patch moves aic7xxx over to the dma_get_required_mask() API and dumps its open coded memory check. It also appears from this bug: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=167049 That 39 bit addressing doesn't work on older cards. I surmise that the AHC_LARGE_SCBS flag is the one that marks cards capable of using 39 bit addressing, so I also folded that check into the code.

Several people noticed we dropped quite a bit on benchmark figures. OK, it was my fault but unfortunately I discovered I ran out of brown paper bags a while ago and forgot to reorder them. The issue is that a construct introduced in the conversion of the driver to use the transport class keyed off whether the block request was tagged or not. However, the aic7xxx driver doesn't properly set up the block layer TCQ (it uses the wrong API), so the driver now things all requests are untagged and we keep it to a queue depth of a single element. Oops. The fix is to use the correct TCQ API. Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

Apparently these are the only drives that try to negotiate IU and QAS at u160 speeds. The aic7xxx driver can't cope with this. The fix is to eliminate the IU and QAS setting routines. I've #if 0'd them out, just in case we ever get the sequencer documentation out of Adaptec, since we'd then be able to fix the driver. Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

The allocation of all of our components should be done in slave alloc. Currently it's rather fancifully refcounted in the queuecommand callback. This patch moves allocation and destroy to their correct places in slave_alloc/slave_destory. Now we can guarantee that everywhere a device is requested, it's actually been allocated, so don't check for this anymore. Additionally, the per device busy timer was the only source of potential use after free. It's been deleted because Linux does the correct thing with busy returns, so there's no need to implement a separate timer in the driver. Finally, implement code that forces all the device parameters to zero (i.e. async and narrow) in the slave alloc, inform the spi class of the bios recorded maximums and wait until slave configure before trying anything more adventurous.
