2023-08-21scsi: qla2xxx: Fix firmware resource trackingQuinn Tran
The storage was not draining I/Os and the work load was not spread out across different CPUs evenly. This led to firmware resource counters getting overrun on the busy CPU. This overrun prevented error recovery from happening in a timely manner. By switching the counter to atomic, it allows the count to be little more accurate to prevent the overrun.

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.

2008-12-29[SCSI] qla2xxx: Refactor qla data structuresAnirban Chakraborty
Following changes have been made to the qla2xxx FC driver in preparation for the multi- queue and future SR IOV hardware. 1. scsi_qla_host structure has been changed to contain scsi host specific data only. 2. A new structure, qla_hw_data is created to contain HBA specific hardware data. 3. Request and response IO specific data strucures are created. 4. The global list of fcports for the hba is not maintained anymore, instead a fcport list is construted on per scsi_qla_host.
