Honour the return value of pci_enable_device(), which
seems to be a desirable thing to do:
2.6.20-rc4
gcc (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)
CC [M] drivers/message/fusion/mptbase.o
drivers/message/fusion/mptbase.c: In function `mpt_resume':
drivers/message/fusion/mptbase.c:1541: warning: ignoring return value
of `pci_enable_device', declared with attribute warn_unused_result
It also in turn has mptscsih_resume() honour the return value of
mpt_resume()
I'm not sure about the handling of the other potential error cases
in mpt_resume(), of which there appear to be many. But this does
seem to be a good start.

Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.
The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around. On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).
Where appropriate, an arch may override the generic storage facility and do
something different with the variable. On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.
Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions. Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller. A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.
I've build this code with allyesconfig for x86_64 and i386. I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.
This will affect all archs. Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
struct pt_regs *old_regs = set_irq_regs(regs);
And put the old one back at the end:
set_irq_regs(old_regs);
Don't pass regs through to generic_handle_irq() or __do_IRQ().
In timer_interrupt(), this sort of change will be necessary:
- update_process_times(user_mode(regs));
- profile_tick(CPU_PROFILING, regs);
+ update_process_times(user_mode(get_irq_regs()));
+ profile_tick(CPU_PROFILING);
I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().
Some notes on the interrupt handling in the drivers:
(*) input_dev() is now gone entirely. The regs pointer is no longer stored in
the input_dev struct.
(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
something different depending on whether it's been supplied with a regs
pointer or not.
(*) Various IRQ handler function pointers have been moved to type
irq_handler_t.

This ugly hack was long overdue to die.
It was a way to print out Sparc interrupts in a more freindly format,
since IRQ numbers were arbitrary opaque 32-bit integers which vectored
into PIL levels. These 32-bit integers were not necessarily in the
0-->NR_IRQS range, but the PILs they vectored to were.
The idea now is that we will increase NR_IRQS a little bit and use a
virtual<-->real IRQ number mapping scheme similar to PowerPC.
That makes this IRQ printing hack irrelevant, and furthermore only a
handful of drivers actually used __irq_itoa() making it even less
useful.

The driver uses msleep_interruptible() in the code path responsible
for resetting the card's ports via the lsiutil command. If a
<ctrl-c> is received during the reset it can leave a port in such
a state that the only way to regain its use is to reboot the system.
Changing from msleep_interruptible() to msleep() corrects the problem.

o Kdump capture kernel boot fails during initialization of MPT fusion driver.
(LSI Logic / Symbios Logic SAS1064E PCI-Express Fusion-MPT SAS (rev 01))
o Problem is easily reproducible, if system crashed while some disk activity
like cp operation was going on.
o After a system crash, devices are not shutdown and capture kernel starts
booting while skipping BIOS. Hence underlying device is left in operational
state. In this case scsi contoller was left with interrupt line asserted
reply FIFO was not empty. When driver starts initializing in the second
kernel, it receives the interrupt the moment request_irq() is called.
Interrupt handler, reads the message from reply FIFO and tries to access
the associated message frame and panics, as in the new kernel's context
that message frame is not valid at all.
o In this scenario, probably we should delay the request_irq() call. First
bring up the IOC, reset it if needed and then should register for irq.
o I have tested the patch with SAS1064E and 53c1030 controllers.

All registered reset callback handlers are called during reset processing.
The mptspi modules has its own reset callback handler, just recently
added for issuing domain validation after host reset. If either the mptsas or
mptfc driver are loaded, this callback could be called. Thus resulting
in domain validation being issued for sas or fibre end devices.
Fix this by having mptbase.c check the bus type against the driver
type and only call the reset handler if they match (or if it's a
non-bus specific reset handler).

mptscsih.c
when firmware reports target is no longer there, return

when the "eh_abort" routine is called, check to see if the
driver has the command or not before looking to see if a reset
is pending. James Smart and I talked about this and believe
that the API for this routine is: if driver doesn't have
command, return SUCCESS. This change helps prevent a target
from being taken offline. SUCCESS is returned because it's
likely that the command completed after error recovery timed
it out but before it could be aborted.
provide a routine to queue work to newly created workq, and
use it.
remove "ioc" from mptscsih_abort() it was only used one time.
the other references were via hd->ioc, so I just moved it....
net change in references to ioc via hd->ioc is zero
move hd->resetPending test and hd->timeouts increment to after
the test for whether the command to be aborted remains known
to the driver
Make certain that the workq exists before queuing work to it.

no longer need to lock rport data structures as I was able to
single thread the code! I fixed up the debug code to
eliminate compilation messages due to type mismatch in the

Initialize and destroy the workq used for the rescan work.
simplify the logic regarding the increment of
fc_rescan_work_count. use post increment and test for zero
vs. pre increment and test for one; eliminate work_count

it doesn't sleep

This is the first half of a patch to add the generic domain validation
to mptspi. It also creates a secondary "virtual" channel for raid
component devices since these are now exported with no_uld_attach.
What Eric and I would have really liked is to export all physical
components on channel 0 and all raid components on channel 1.
Unfortunately, this would result in device renumbering on platforms with
mixed RAID/Physical devices which was considered unacceptable for
userland stability reasons.
Still to be done is to plug back the extra parameter setting and DV
pieces on reset and hotplug.
