A Gentoo bug report [1] showed that as of 2.6.31 lpfc only uses INTx interrupts.
This patch restores lpfc's ability to support MSI-X/MSI interrupts that the
"Addition of SLI4 Interface - Base Support" patch [2] broke.
It reestablishes MSI-X as the default interrupt method and in case MSI-X is not
supported lpfc_sli{4,}_enable_intr fallbacks to MSI and then to INTx.
[1]: http://bugs.gentoo.org/show_bug.cgi?id=296319
[2]: commit da0436e915a5c17ee79e72c1bf978a4ebb1cbf4d
[James Smart:
Background:
Nothing Broke. This was intended.
We had originally enabled MSI-X by default, but in qualification within the
last 12 months, we encountered a major catch-22:
There were at least 4 platforms, from 2 major OEMs, that :
- Say they support MSI-X - platform routines work and act as if they do.
- We enable it, generate a test interrupt to check they really do deliver it,
and it works.
- But shortly after attachment, the system hangs or loses interrupts,
resulting in a bad system behavior.
Given the distro's picking up the 2.6.32 kernel, we had to stick with a
default of MSI-X off, with user-enabled MSI-X as these platforms couldn't get
fixed.
However, we're also now encountering platforms that require MSI-X and never
INTx, so we must change. It's desired also for also for performance reasons.
So - now (2.6.33) is the right time to re-enable MSI-X by default.

In testing 2.6.31 on one of our ia64 platforms I've encountered a hang
due to the driver using hardware ATEs which are a limited resource.
This is because the driver does not set the dma consistent mask to

Some of our virtual SCSI hosts don't have a proper bus parent at the
top, which can be a problem for doing DMA on them
This patch makes the host device cache a pointer to the physical bus
device and provides an extra API for setting it (the normal API picks
it up from the parent). This patch also modifies the qla2xxx and lpfc
vport logic to use the new DMA host setting API.

The checksum format is orthogonal to whether the protection information
is being passed on beyond the HBA or not. It is perfectly valid to use
a non-T10 CRC with WRITE_STRIP and READ_INSERT.
Consequently it no longer makes sense to explicitly refer to the
conversion in the protection operation. Update sd_dif and lpfc
accordingly.

Many developers use "/debug/" or "/debugfs/" or "/sys/kernel/debug/"
directory name to mount debugfs filesystem for ftrace according to
./Documentation/tracers/ftrace.txt file.
And, three directory names(ex:/debug/, /debugfs/, /sys/kernel/debug/) is
existed in kernel source like ftrace, DRM, Wireless, Documentation,
Network[sky2]files to mount debugfs filesystem.
debugfs means debug filesystem for debugging easy to use by greg kroah
hartman. "/sys/kernel/debug/" name is suitable as directory name
of debugfs filesystem.
