PATCH [0/15] qla2xxx: summary of changes...

James,

Please apply the following patches I'm about to send to update the qla2xxx driver. A summary of the patches can be found towards the end of this message.

With the exception of the rather large firmware image update (direct pointer to bzip'd patch listed), subsequent messages will contain inlined patches.

All patches can be found at the following URL:

ISP dump routine fixes:

o Properly release hardware_lock in failure path.

o Fix inability to complete ISP2100 dump, by properly reseting the RISC after register reads.

Remove flash support from embedded driver:

o Remove unused option-rom variables from host structure.
o Remove flash manipulation routines.

Older, notably the ISP2100, chips have some contraints for the request queue depth and number of scatter-gather elements allowed for a given command. For this chip, reduce request queue size to 128 and maximum number of scatter-gather entries for a command to 32.

Fix problem where port ID binding would not be honoured when a device was moved within the fabric.

Issue a kernel warning message before initiating an ISP abort (big hammer) -- additional debugging mechanism in case of event.

Fix problem where the driver would incorrectly down-cast the target loop_id while retrieving link statistics.

Cleanup retrieval and update of firmware options:

o Update only valid for non-(2[12]00) ISPs.
o Instruct firmware to return completed IOCBs without waiting for an ABTS to complete.

Fix problem where during ISP initialization in a volatile topology (i.e. fabric environment with large number of streaming RSCNs) the driver would loop indefinitely or hang due to termination of an invalid thread pid.

Fix several problems when handling commands issued to tape devices:

1) insure commands are not prematurely returned to the mid-layer with a failed status during loop/fabric transitions.

2) tape commands tend to have rather 'long' timeout values, unfortunately, as the these values increase into the 17 to 20 minute range (and larger), the cumulative skew of the RISC's own timer result in commands being held for seconds beyond their defined timeout values. Compensate for this in the driver's command timeout function.

Jeremy Higdon <jeremy () sgi ! com>:

For those to whom this is new (it was discussed on linux-kernel and linux-ia64 I believe), normal PCI register reads imply that PCI DMA writes that occured prior to the PCI MMR (memory mapped register) read (on the PCI bus) will be reflected in system memory once the MMR read is complete.

On our platforms, we can speed up the MMR read significantly if that ordering requirement is "relaxed".

So I attempted to find the common register reads that don't have a need for this ordering so that I could make them use this faster read.

/proc file updates:

o Address 'unaligned access' message on ia64 platorms while displaying bit-field flags.

o Iterate through the the OS target array to display target ID bindings.

RIO/ZIO fixes:

o Reduce register access during RIO operation by checking for a 'dirtied' signature.

o Fix problem where ZIO mode handling could result in a nasty recursive call-frame.

Misc. driver scrubbing:

o Use kernel #define for PCI command register bit.

o Fix rate-limiting check the queue-depth module parameter.

o Clean-up comments.
