| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This started as a PCI reference fixup but to do that I need to build it, to build it I need to fix it and its full of 32bitisms and uglies. It has been resurrected, I'm not sure if this is a thank you for the work on the license stuff or punishment for some unknown misdeed however 8). I've also fixed a memory scribble in the init code. One oddity - the changes from HZ * to constants are deliberate. Whoever originally wrote the code (or cleaned it up) used HZ for a cycle timing loop even though is not HZ related. I've put it back to the counts used in the old days when the driver was most used. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn: Until the system is stabilized, I am suggesting the enclosed modification to prevent the driver from tickling the panic. Once sysfs and friends are stabilized, the patch may be backed out. We have yet to evaluate if we really want to relinquish existing Scsi Devices in any case, holding on to them as configuration of arrays comes and goes makes some sense as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn: The only real difference between the rkt and rx platform modules is the offset of the message registers. This patch recognizes this similarity and simplifies the driver to reduce it's code footprint and to improve maintainability by reducing the code duplication. Visibly, the 'rkt.c' portion of this patch looks more complicated than it really is. View it as retaining the rkt-only specifics of the interface.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn: I am placing this functionality into an insmod parameter. Normally the physical components are exported to sg, and are blocked from showing up in sd. Note that the pass-through I/O path via the driver through the Firmware to the physical disks is not an optimized path, the card is designed for Hardware RAID, elevator sorting and caching. This should not be used as a means for utilizing the aacraid based controllers as a generic scsi/SATA/SAS controller, performance should suck by a few percentage points, any RAID meta-data on the drives will confuse the controller about who owns the drives and there is a high risk of destroying content in both directions.

Two callers assume the target comes back with reference unincremented and the third assumes its incremented. Fix by always making the reference incremented on return.

Thus, it is called whenever the dev_loss_tmo fires, or when the rport is deleted due to other circumstances (module unload, etc). It is expected that the callback will initiate the termination of any outstanding i/o on the rport. - fast_io_fail_tmo and LLD callback: There are some cases where it may take a long while to truly determine device loss, but the system is in a multipathing configuration that if the i/o was failed quickly (faster than dev_loss_tmo), it could be redirected to a different path and completed sooner.

It is a followup to the original RFC at: http://marc.theaimsgroup.com/?l=linux-scsi&m=114530667923464&w=2 and the initial posting at: http://marc.theaimsgroup.com/?l=linux-scsi&m=115507374832500&w=2 The patch has been updated to optimize the send path, per the discussions in the initial posting. Per discussions at the Storage Summit and at OLS, we are to use netlink for async events from transports. Also per discussions, to avoid a netlink protocol per transport, I've create a single NETLINK_SCSITRANSPORT protocol, which can then be used by all transports. This patch: - Creates new files scsi_netlink.c and scsi_netlink.h, which contains the single and shared definitions for the SCSI Transport. It is tied into the base SCSI subsystem intialization. Contains a single interface routine, scsi_send_transport_event(), for a transport to send an event (via multicast to a protocol specific group). - Creates a new scsi_netlink_fc.h file, which contains the FC netlink event messages - Adds 3 new routines to the fc transport: fc_get_event_number() - to get a FC event # fc_host_post_event() - to send a simple FC event (32 bits of data) fc_host_post_vendor_event() - to send a Vendor unique event, with arbitrary amounts of data. Note: the separation of event number allows for a LLD to send a standard event, followed by vendor-specific data for the event. Note: This patch assumes 2 prior fc transport patches have been installed: http://marc.theaimsgroup.com/?l=linux-scsi&m=115555807316329&w=2 http://marc.theaimsgroup.com/?l=linux-scsi&m=115581614930261&w=2 Sorry - next time I'll do something like making these individual patches of the same posting when I know they'll be posted closely together.
