scsi: ipr: Use pci_irq_allocate_vectors

2016-11-08T22:29:46+00:00

Switch the ipr driver to use pci_alloc_irq_vectors.  We need to two
calls to pci_alloc_irq_vectors as ipr only supports multiple MSI-X
vectors, but not multiple MSI vectors.

Otherwise this cleans up a lot of cruft and allows to use a common
request_irq loop for irq types, which happens to only iterate over a
single line in the non MSI-X case.

scsi: ipr: Don't log unnecessary 9084 error details

2016-09-19T15:57:33+00:00

A 9084 error gets logged by the ipr adapter when adapter raw mode gets
enabled. A bunch of unformatted hex data also gets logged for this
error, which is of little use, so let's avoid logging it by default in
order to avoid the log getting polluted with useless data.

scsi: ipr: Add asynchronous error notification

2016-08-26T03:39:15+00:00

This patch implements functions for pushing HCAM (host controlled
asynchronous messages) error buffers to userspace through sysfs
attributes.  Reads to the "async_err_log" attribute will result in a
single HCAM buffer being copied to userspace; one can process the next
HCAM buffer by writing any string to the same attribute.

A new list was added to the ioa_cfg structure to store the HCAM buffers
for later reporting. We also send a KOBJ_CHANGE event whenever a new
HCAM buffer is made available to userspace.

ipr: Wait to do async scan until scsi host is initialized

2016-07-27T04:32:07+00:00

When performing an async scan, make sure the kthread doing scanning
doesn't start before the scsi host is fully initialized.

irq_poll: make blk-iopoll available outside the block layer

The new name is irq_poll as iopoll is already taken.  Better suggestions

ipr: Issue Configure Cache Parameters command.

2015-11-10T00:32:08+00:00

Some new adapters require a special Configure Cache Parameters command
to enable the adapter write cache, so send this during the adapter
initialization if the adapter requires it.

ipr: Inquiry IOA page 0xC4 during initialization.

2015-11-10T00:31:37+00:00

Add an IOA Inquiry command for Page 0xC4 during IOA initialization to
collect cache capabilities, particularly to check if Sync IOA Write
Cache is supported.

Inquiry will happen right after Cap Inquiry on page 0xD0; and will
execute only if the "Supported Pages" field in Inquiry Page 0x0 shows
support for Page 0xC4.  Otherwise, assume Sync IOA Write Cache is
not supported.

ipr: Add delay to ensure coherent dumps.

2015-11-10T00:29:54+00:00

Add a holding pattern prior to collecting dump data, to wait for the IOA
indication that the Mailbox register is stable and won't change without
an explicit reset.  This ensures we'll be collecting meaningful dump
data, even when dumping right after an adapter reset.

In the event of a timeout, we still force the dump, since a partial dump
still might be useful.
