2008-07-26[SCSI] qla2xxx: Additional NPIV corrections.Andrew Vasquez
Minor fixes addressing: - rport managements during vport deletion. - acquire proper physical-ha during qla24xx_abort_command() and qla24xx_queuecommand() - do not needlessly acquire the pha for non-NPIV capable ISPs.

2008-07-26[SCSI] qla2xxx: Issue proper ISP callbacks during stop-firmware.Andrew Vasquez
As the original code would incorrectly call the non-ISP24xx/25xx callbacks during recovery, a stop-firmware failure could result in improper bit-banging of the RISC and in some cases manifest in a NMI-watchdog trigger due to the RISC not coming out of its reset state.

2008-07-26[SCSI] qla2xxx: Correct rport/fcport visibility-state handling during ↵Seokmann Ju
loop-resync. There were several issues here, one, during RSCN handling if a follow-on RSCN occurred (within interrupt context) the DPC thread could inadvertantly leave the fcport in a stale lost state. Secondly, scheduled rport removal is handled exclusively by the 'parent' DPC thread, so wake up the proper thread. Finally, process vport loop-resync's only when the vport has in an "active" state (ID acquired).

2008-07-26[SCSI] qla2xxx: Swap enablement order of EFT and FCE.Andrew Vasquez
The firmware group has suggested that FCE (Fibre Channel Event) tracing be enabled prior to EFT (Extended Firmware Tracing) to maximize the capturing of data on the wire. This change has no real semantic effect on driver operation, as it's mostly a shuffling of code.

2008-07-26[SCSI] qla2xxx: Retrieve board serial-number and description from VPD.Joe Carnuccio
Recent ISPs have this information written at manufacturing time, so use the information. This also reduces future churn of the qla_devtbl.h file contents, as the driver can now depend on the information to be present in VPD.

2008-07-26[SCSI] qla2xxx: Allow the user the option of disabling iIDMA.Andrew Vasquez
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). So, to handle such conditions, allow the user the ability to indirectly disable the FM commands by disabling iIDMA with the ql2xiidmaenable module-parameter.

2008-03-03[SCSI] qla2xxx: Correct usage of inconsistent timeout values while issuing ↵Andrew Vasquez
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.

2008-03-03[SCSI] qla2xxx: Correct needless clean-up resets during shutdown.Andrew Vasquez
There's no point in hitting the RISC with what will most assuredly be an unsucessful reset of the RISC hardware if the initial stop-firmware mailbox command fails with a time-out status. Instead, to avoid what could amount to a lengthy stop-firmware/detect-failure/reset-risc loop, continue with driver unloading and discard the stop-firmware requirement.

2008-01-23[SCSI] qla2xxx: Correct late-memset() of EFT buffer.Andrew Vasquez

2008-01-23[SCSI] qla2xxx: Add Fibre Channel Event (FCE) tracing support.Andrew Vasquez
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.

2007-07-11PCI: Change all drivers to use pci_device->revisionAuke Kok
Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance.
