Wayne Boyer 3feeb89d40 [SCSI] ipr: add workaround for MSI interrupts on P7
This patch adds some additional logic to the interrupt service routine to fix
a potential problem where an MSI interrupt does not get cleared the first time.

Wayne Boyer 1be7bd82bf ipr: differentiate pci-x and pci-e based adapters
MSI has only been tested on and known to work with PCI-E based adapters.  This
patch adds a field to struct ipr_chip_t to indicate which type of interrupt to
use based on what is known about the chip.

Wayne Boyer 95fecd9039 ipr: add test for MSI interrupt support
The return value from pci_enable_msi() can not always be trusted.  This patch
adds code to generate an interrupt after MSI has been enabled and tests
whether or not we can receive and process it.  If the tests fails, then fall
back to LSI.

Brian King 463fc696ed [SCSI] ipr: Use PCI-E reset API for new ipr adapter
Use a newly added PCI API to issue a PCI Fundamental reset
(warm reset) to a new ipr PCI-E adapter. Typically, the
ipr adapter uses the start BIST bit in config space to reset
an adapter. Issuing start BIST on this particular adapter
results in the PCI-E logic on the card losing sync, which
causes PCI-E errors, making the card unusable. The only reset
mechanism that exists on this hardware that does not have this
problem is PCI Fundamental reset (warm reset).

Brian King 4733804c9f [SCSI] ipr: Fix adapter initialization failure
Since scsi core is always sending scatterlists now, remove
some code which was written with the bad assumption that
a small transfer would not be sent down in a scatterlist.
Without this fix, the ipr driver ends up sending garbage
data to the adapter following a reset, causing it to
fail the reset and take the adapter offline.

brking@us.ibm.com ce155ccecd [SCSI] ipr: Driver initialization fix for kexec/kdump
When kexec booting a kernel when the previous kernel did not
call ipr's shutdown method, the ipr adapter does not get
properly initialized, which can result in the ipr adapter
completing commands issued by the previous kernel. Fix ipr
to detect this scenario by reading the adapter's interrupt
mask register and the microprocessor interrupt register.
If the interrupt mask register indicates that interrupts
are enabled or the reset alert bit is set when the card is
probed, this means the card is in an unknown state and we
hard reset the card.

brking@us.ibm.com ee0a90fa3e [SCSI] ipr: Support new device queueing model
New ipr adapters support a new device queueing model in the
adapter firmware. The queueing model is the NACA queueing model,
but it does not mean use of NACA is required. The new model removes
some of the adapter firmware queue state that made handling QERR=0
almost impossible. The queueing model on older adapters included the
concept of a queue frozen state, which would freeze the response
queue in the adapter when a check condition occurred, requiring a
a primitive to resume the queue. The new queueing model removes this
complexity.
