* [SCSI] qla2xxx: changes in multiq codeAnirban Chakraborty2008-12-291-78/+98
| | | | | | | | | | Following changes have been made: 1. Scan outstanding commands only in the queue where it is submitted 2. Update queue registers directly in the fast path 3. Queue specific BAR is remapped only for multiq capable adapters Signed-off-by: Anirban Chakraborty <anirban.chakraborty@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* [SCSI] qla2xxx: add support for multi-queue adapterAnirban Chakraborty2008-12-291-148/+275
| | | | | | | | | | | | | | | | | | Following changes have been made. 1. qla_hw_data structure holds an array for request queue pointers, and an array for response queue pointers. 2. The base request and response queues are created by default. 3. Additional request and response queues are created at the time of vport creation. If queue resources are exhausted during vport creation, newly created vports use the default queue. 4. Requests are sent to the request queue that the vport was assigned in the beginning. 5. Responses are completed on the response queue with which the request queue is associated with.

| | | | | | | | | | The following patch changes the handling of bus reset when issued from a vport. In the bus reset code, an extra check is made to make sure that the lip reset is not done before resetting the targets if the bus reset came from a vport.

* [SCSI] qla2xxx: Return a FAILED status when abort mailbox-command fails.Michael Reed2008-11-051-0/+1
| | | | | | | | | | | | | | | | | Mike Reed noted (https://bugzilla.novell.com/show_bug.cgi?id=421330) that the driver was incorrectly returning a SUCCESS status if the driver's request to the firmware to abort a command failed. By doing so, the mid-layer believed, incorrectly, that the command has completed and has been returned (ultimately clearing scsi_cmnd.request_buffer) yet the driver still has the command. What should correctly happen is a mid-layer escalation (device-reset, etc.) of recovery during which the driver will eventually return the outstanding commands to the mid-layer.

* [SCSI] qla2xxx: Explicitly tear-down vports during PCI remove_one().Andrew Vasquez2008-08-161-3/+10
| | | | | | | | | | | | | | | | | | | | | During internal testing, we've seen issues (hangs) with the 'deferred' vport tear-down-processing typically accompanied with the fc_remove_host() call. This is due to the current implementation's back-end vport handling being performed by the physical-HA's DPC thread where premature shutdown could lead to latent vport requests without a processor. This should also address a problem reported by Gal Rosen (http://marc.info/?l=linux-scsi&m=121731664417358&w=2) where the driver would attempt to awaken a previously torn-down DPC thread from interrupt context by implicitly calling wake_up_process() rather than the driver's qla2xxx_wake_dpc() helper. Rather, than reshuffle the remove_one() device-removal code, during unload, depend on the driver's timer to wake-up the DPC process, by limiting wake-ups based on an 'unloading' flag.

| | | | | | | | | | | | | | iIDMA support requires the driver issue several additional fabric-managegment (FM) commands per port discovered during SNS scanning -- GFPN (Get Fabric Port Name) and GPSC (Get Port Speed Capabilities). It has been found during testing that some switches do not respond as *well* as expected to these commands (silence -- no ACC nor BS_RJT).

This allows for a limited view of the FC traffic through the ISP without using a FC analyzer. This can be useful in situations where a physical connection to the FC bus is not possible. The driver exports this information in two ways -- first, via a debugfs node exported for all supported ISPs under: <debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce where a read of the 'fce' file will provide a snapshot of the firmware's FCE buffer; and finally, the FCE buffer will be extracted during a firmware-dump scenario.
