* [SCSI] qla2xxx: defer topology discovery to DPC thread during initialization.Andrew Vasquez2006-11-221-22/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Modify intialization semantics: - perform basic hardware configuration only (as usual) - allocate resources - load and execute firmware - defer link (transport) negotiations to the DPC thread - again the code in qla2x00_initialize_adapter() to stall probe() completion was needed for legacy-style scanning. - DPC thread stalls until probe() complete. - before probe() completes, set DPC flags to perform loop-resync logic (similar to what's done during cable-insertion/removal). Benefits: user does not have to wait 20+ seconds in case the FC cable is unplugged during driver load, code consolidation (removal of redundant link negotiation logic during initialize_adaoter()), and finilly, the driver no longer needs to defer the fc_remote_port_add() calls to hold off lun-scanning prior to returning from the probe() function.

| * [SCSI] qla2xxx: Workaround D3 power-management issues.Andrew Vasquez2006-10-251-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Early ISP2432 parts have a known hardware issue when coming out of a D3 hot state. This issue can result in a hung PCIe link. Recent firmwares contain a workaround whereby the stop-firmware mailbox command prevents the ISP from entering the D3 hot state. In order to ensure that the workaround succeeded the driver must verify that the stop-firmware mailbox command completes successfully. In the event of a failure, the driver attempts a shutdown-retry after resetting the ISP and re-executing firmware.

* [SCSI] qla2xxx: Add iIDMA support.Andrew Vasquez2006-10-031-1/+1
| | | | | | | | | | | | | | | | iIDMA (Intelligent Interleaved Direct Memory Access) allows for the HBA hardware to send FC frames at the rate at which they can be received by a target device. By taking advantage of the higher link rate, the HBA can maximize bandwidth utilization in a heterogeneous multi-speed SAN. Within a fabric topology, port speed detection is done via a Name Server command (GFPN_ID) followed by a Fabric Management command (GPSC). In an FCAL/N2N topology, port speed is based on the HBA link-rate. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] qla2xxx: Correct PLOGI retry logic.Andrew Vasquez2006-08-261-3/+0
| | | | | | | | | | | | | | Original code attempts to retry PLOGIs to fcports that are FCP_TARGETs only. If the driver never performed a successful PLOGI/PRLI, the port-type would never be assigned, and the relogin logic would silently drop the request (and thus the port would not be recognized and registered). The fix is relatively straightforward, drop the FCP_TARGET-only check. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] qla2xxx: Fix to allow to reset devices using sg interface (sg_reset).Vladislav Bolkhovitin2006-08-061-9/+3
| | | | | | | | | | | | | | | | | | | | Currently it is impossible to reset provided by Qlogic QLA2xxx driver SCSI devices externally using corresponding sg devices, particularly via sg_reset utility, because qla2xxx driver in qla2xxx_eh_device_reset() function checks if the input scsi_cmnd has its private data (CMD_SP()) attached. Then the found pointer isn't used anywhere inside of qla2xxx_eh_device_reset(). If the RESET request comes from sg device, it doesn't have such private data. The attached patch removes check for non-NULL CMD_SP() from qla2xxx_eh_device_reset(), hence allows to reset QLA2xxx's devices using corresponding sg devices. AV: change applies to bus/host reset handlers as well.
