Older tracing of driver messages was to:
- log only debug messages to kernel main trace buffer; and
- log only if extended logging bits corresponding to this message is
off
This has been modified and extended as follows:
- Tracing is now controlled via ql2xextended_error_logging_ktrace
module parameter. Bit usages same as ql2xextended_error_logging.
- Tracing uses "qla2xxx" trace instance, unless instance creation have
issues.
- Tracing is enabled (compile time tunable).
- All driver messages, include debug and log messages are now traced in
kernel trace buffer.
Trace messages can be viewed by looking at the qla2xxx instance at:
/sys/kernel/tracing/instances/qla2xxx/trace
Trace tunable that takes the same bit mask as ql2xextended_error_logging
is:
ql2xextended_error_logging_ktrace (default=1)
