* [SCSI] qla2xxx: Properly acknowledge IDC notification messages.Andrew Vasquez2009-02-10
| | | | | | | | | | | | | To ensure smooth operations amongst the FCoE and NIC side components of the ISP81xx chip, the FCoE driver (qla2xxx) must ensure the 10gb NIC driver (qlge) does not timeout waiting for IDC (Inter-Driver Communication) acknowledgments. The acknowledgment requirements are trivial -- a simple mirroring of incoming mailbox registers during the AEN to a process-context capable mailbox command.

Correct response-queue-0 processing by instructing the firmware to run with interrupt-handshaking disabled, similarly to what is now done for all non-0 response queues. Since all response-queues now run in the same mode, the driver no longer needs the hot-path 'is-disabled-HCCR' test.

* [SCSI] qla2xxx: Always serialize mailbox command execution.Andrew Vasquez2009-01-25
| | | | | | | | | | | Original code would incorrectly bypass serialization if the DPC thread were performing a big-hammer operation (ISP abort). This short circuit, though rare, would subsequently stomp on a secondary thread's mailbox command execution. Found during ISP81XX testing.

| | | | | | | | | | | | | | | | | | 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.

* [SCSI] qla2xxx: Explicitly tear-down vports during PCI remove_one().Andrew Vasquez2008-08-16
| | | | | | | | | | | | | | | | | | | | | 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.

In the process of adding reset support, collapse and consolidate large sections of mailbox-command (TMF issuance) codes, generalize the two 'wait-for-commands-to-complete' functions, and add a generic-reset routine for use by midlayer reset functions.

| | | | | | | | | | | | | | | | | ELS commands. The original code would incorrectly hardcode ELS timeout values rather than using the traditional '2 * r_a_tov' value. In some cases, the hardcoded values would be larger than the mailbox-command-timeout and result in a needless BIG_HAMMER (ISP reset), the typical recovery mechanism employed in such cases. The second defect in the original code was in the assignment of the default 'ha->r_a_tov' to twice the traditional value. Correct this by setting the value to 10 seconds.

* [SCSI] qla2xxx: Add Fibre Channel Event (FCE) tracing support.Andrew Vasquez2008-01-23
| | | | | | | | | | | | | | | | | | | | | FCE support enables the firmware to record FC extended link services and basic link services frames which have been transmitted and received by the ISP. 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.
