2011-08-29[SCSI] qla2xxx: Add support for ISP82xx to capture dump (minidump) on failure.Giridhar Malavali
Minidump allows us to catpure a snapshot of the firmware/hardware states at the time of failure for further analysis.

2011-07-27[SCSI] qla2xxx: Code changes to support new dynamic logging infrastructure.Saurav Kashyap
The code is changed to support the new dynamic logging infrastructure. Following are the levels added. Default is 0 - no logging. 0x40000000 - Module Init & Probe. 0x20000000 - Mailbox Cmnds. 0x10000000 - Device Discovery. 0x08000000 - IO tracing. 0x04000000 - DPC Thread. 0x02000000 - Async events. 0x01000000 - Timer routines. 0x00800000 - User space. 0x00400000 - Task Management. 0x00200000 - AER/EEH. 0x00100000 - Multi Q. 0x00080000 - P3P Specific. 0x00040000 - Virtual Port. 0x00020000 - Buffer Dump. 0x00010000 - Misc. 0x7fffffff - For enabling all logs, can be too many logs. Setting ql2xextended_error_logging module parameter to any of the above value, will enable the debug for that particular level. Do LOGICAL OR of the value to enable more than one level.

2011-07-27[SCSI] qla2xxx: Basic infrastructure for dynamic logging.Saurav Kashyap
This patch adds the dynamic logging framework to the qla2xxx driver. The user will be able to change the logging levels on the fly i.e. without load/unload of the driver. This also enables logging to be enabled for a particular section of the driver such as initialization, device discovery etc. Signed-off-by: Saurav Kashyap <saurav.kashyap@qlogic.com> Signed-off-by: Giridhar Malavali <giridhar.malavali@qlogic.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

2010-12-23[SCSI] qla2xxx: Update FCP priority information to firmware before sending IOsMadhuranath Iyengar
The FCP priority info was not being updated properly in certain situations. Here are the changes that needs to be done to take care of this issue: 1. No need to check fcport->state for FCS_UNCONFIGURED in qla24xx_update_fcport_fcp_prio(), since an invalid loop id check is already performed which is sufficient. 2. Add the missing qla24xx_update_fcport_fcp_prio() function call within qla2x00_update_fcport() function, so that the priority info is updated on every port addition or change. 3. Perform proper adapter types checking. 4. Other changes, associated with DEBUG/printk's and parameter passing.

2010-12-23[SCSI] qla2xxx: Added support for quiescence mode for ISP82xx.Saurav Kashyap
Support is added for quiescence mode. This feature is for P3P adapters. Any of the functions can put the firmware into quiescence state. All the others have to ack that request. During quiescence mode current commands are processed and all the new incoming I/Os are blocked. Loop resync is performed after firmware comes out of quiescence state.

2010-07-28[SCSI] qla2xxx: Use GFF_ID to check FCP-SCSI FC4 type before logging into ↵Chad Dupuis
Nx_Ports The default method that qla2xxx uses is the GID_PT nameserver command to get a list of Nx_Ports. This patch adds a GFF_ID call for each port returned by GID_PT to get the FC4 type. If the FC4 type is not FCP SCSI then the qla2xxx driver will not record that port in it's port database. For switches that do not support the GFF_ID command, the behavior will be for qla2xxx to store that port anyways.

2010-05-16[SCSI] qla2xxx: Support for asynchronous TM and Marker IOCBs.Madhuranath Iyengar
Currently we can only issue the task management (TM) commands via the mailbox mechanism. This is a limitation, since only one mailbox command can be issued at a time. The purpose of this effort is to provide support for issuing and processing the respose to TM and Marker IOCBs asynchronously. Towards achieving this, the consolidated srb architecture that is currently used for BSG and IOCB/Logio commands has been enhanced and used.
