Subject: [PATCH v2 RESEND 00/23] scsi: Use pci_enable_msix_range() instead of pci_enable_msix()

Hello,

This is a series of mostly trivial patches. Once accepted,
we could phase out pci_enable_msix() interface.

As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range() or pci_enable_msi_exact()
and pci_enable_msix_range() or pci_enable_msix_exact()
interfaces.

Thanks!

Subject: [PATCH v2 RESEND 13/23] megaraid: Fail resume if MSI-X re-initialization failed

Currently the driver fails to analize MSI-X re-enablement
status on resuming and always assumes the success. This
update checks the MSI-X initialization result and fails
to resume if MSI-Xs re-enablement failed.

Currently the driver falls back to INTx mode when MSI-X

for chips that also support MSI. This update changes that
behaviour and falls back to MSI mode in case MSI-X mode
initialization failed.

Hi Jayamohan,

Could you please review this patch?

Thanks!

I've applied those few patches that did get a review to the
drivers-for-3.17 branch. It still would be great if someone could help
reviewing the others.

Hi,
patch looks good.

A correction in pm8001_request_irq might be added too to allow
the INT-X path when pm8001_setup_msix fails, but that is not part
of this fix.

There's actually an equivalent fix already in through one of the
previous pm8001 updates, so I skipped this one even if it already had an
ACK. The following pm8001 applied just fine, though. Take a look, as
I've already pushed out the updated drivers branch.

I'm a bit confused - you were not commenting my text above I think?

I see in drivers-for-3.17 this patch already applied 5607de7
but not yet the next one (18/23) which also has a review, is there another ack needed?

Looks like I got a bit confused due to a non-applying patch, but it
seems like the one that failed was the second one. I'll look at it time
permitting, but if someone familar with pm8001 can fix the reject for me
that would help me greatly!

Hmm.. 18/23 applies with a minor fuzz against
git://git.infradead.org/users/hch/scsi-queue.git drivers-for-3.17

Okay, it was just git-am being goofy then. I'll take care of it.
