-config TIPC_LOG
- int "Size of log buffer"
- depends on TIPC_ADVANCED
- range 0 32768
- default "0"
- help
- Size (in bytes) of TIPC's internal log buffer, which records the
- occurrence of significant events. Can range from 0 to 32768 bytes;
- default is 0.
-
- There is no need to enable the log buffer unless the node will be
- managed remotely via TIPC.
-
-config TIPC_DEBUG
- bool "Enable debugging support"
- default n
- help
- Saying Y here enables TIPC debugging capabilities used by developers.
- Most users do not need to bother; if unsure, just say N.
-
- Enabling debugging support causes TIPC to display data about its
- internal state when certain abnormal conditions occur. It also
- makes it easy for developers to capture additional information of
- interest using the dbg() or msg_dbg() macros.
