Clear virtual links was not propagated upwards to bfa from fw. This resulted in HBA and switch being in an inconsistent state. So defined a new LPS event for clear virtual link on a vport, and also now clear virtual link on a baseport, is sent as a link down event from the fw. Signed-off-by:

RAID attributes uses scsi_is_sdev_device() to gate some SCSI specific checking code. This causes two problems. Firstly if SCSI == n just defining scsi_is_sdev_device() to return false might not be enough to prevent gcc from emitting the code (and thus referring to undefined symbols), so this needs surrounding with an ifdef. Secondly, using scsi_is_sdev_device() when SCSI is either y or m gives a subtle problem in the m case: raid_attrs must also be m to use the symbol. Do the usual Kconfig jiggery-pokery to fix this.

Commit e3deec09 incorrectly assumed that the B0 and B1 page lengths were limited to 32 bytes. The B0 VPD page length is defined to be 64 bytes when the device supports thin provisioning. B1 is always defined to be 64 bytes. Signed-off-by:

This uses the scatter-gather chaining feature of Smart Array controllers. 32 scatter-gather elements are embedded in the "command list", and the last element in the list may be marked as a "chain pointer", and point to an additional block of scatter gather elements. The precise number of scatter gather elements supported is dependent on the particular kind of Smart Array, and is determined at runtime by querying the hardware. Signed-off-by:

The intent of the scan thread was to allow a UNIT ATTENTION/LUN DATA CHANGED condition encountered in the interrupt handler to trigger a rescan of devices, which can't be done in interrupt context. However, we weren't able to get this to work, due to multiple such UNIT ATTENTION conditions arriving during the rescan, during updating of the SCSI mid layer, etc. There's no way to tell the devices, "stand still while I scan you!" Since it doesn't work, there's no point in having the thread, as the rescan triggered via ioctl or sysfs can be done without such a thread. Signed-off-by:

Adds support for resuming from suspend for IBM VFC devices. We may have lost an interrupt over the suspend, so we just kick the interrupt handler to process anything that is outstanding. We expect to find a transport event indicating we need to reestablish our CRQ. Signed-off-by:

This patch adds the PCI ID definitions for new adapters based on the next generation 64 bit IOA PCI interface chip. New entries have been added to the ipr_pci_table[] array for the adapters and to the ipr_chip[] array for the new versions of the chip. Older entries have been removed for cards that did not ship.

This patch adds a reboot notifier that will issue a shutdown prepare command to all adapters. This helps to prevent a problem where the primary adapter can get shut down before the secondary adapter and cause the secondary adapter to fail over and log and error. This patch also removes the "enable_cache" paramater as it is obsolete. Write cache for an adapter is now controlled from the iprconfig utility. Signed-off-by:

This patch fixes the request setup code for mode selects. I got the fixes from Hannes Reinecke while trying to hunt down some problems and merged it into one patch. I am sending it because Hannes is busy with other things. The patch fixes: - setting of the length for mode selects. - setting of the data direction for mode select 10. Signed-off-by:
