+config RAMLOG
+ bool "RAM log device support"
+ default n
+ ---help---
+ This is a driver that was intended to support debugging output,
+ aka syslogging, when the normal serial output is not available.
+ For example, if you are using a telnet or USB serial console,
+ the debug output will get lost. However, the RAMLOG device should
+ be usable even if system logging is disabled.
+
+ This driver is similar to a pipe in that it saves the debugging
+ output in a FIFO in RAM. It differs from a pipe in numerous
+ details as needed to support logging.
+
+if RAMLOG
+config RAMLOG_SYSLOG
+ bool "Use RAMLOG for SYSLOG"
+ default n
+ depends on SYSLOG
+ ---help---
+ Use the RAM logging device for the syslogging interface. If this feature
+ is enabled (along with SYSLOG), then all debug output (only) will be re-directed
+ to the circular buffer in RAM. This RAM log can be view from NSH using the
+ 'dmesg'command.
+
+ Do not enable more than one SYSLOG device.
+
+config RAMLOG_CONSOLE
+ bool "Use RAMLOG for /dev/console"
+ default n
+ depends on DEV_CONSOLE
+ ---help---
+ Use the RAM logging device as a system console. If this feature is enabled (along
+ with DEV_CONSOLE), then all console output will be re-directed to a circular
+ buffer in RAM. This is useful, for example, if the only console is a Telnet
+ console. Then in that case, console output from non-Telnet threads will go to
+ the circular buffer and can be viewed using the NSH 'dmesg' command.
+
+config RAMLOG_CONSOLE_BUFSIZE
+ int "RAMLOG buffer size"
+ default 1024
+ depends on RAMLOG_SYSLOG || RAMLOG_CONSOLE
+ ---help---
+ Size of the console RAM log. Default: 1024
+
+config RAMLOG_CRLF
+ bool "RAMLOG CR/LF"
+ default n
+ ---help---
+ Pre-pend a carriage return before every linefeed that goes into the RAM log.
+
+config RAMLOG_NONBLOCKING
+ bool "RAMLOG non-block reads"
+ default y
+ ---help---
+ Reading from the RAMLOG will never block if the RAMLOG is empty. If the RAMLOG
+ is empty, then zero is returned (usually interpreted as end-of-file).
+
+config RAMLOG_NPOLLWAITERS
+ int "RAMLOG number of poll waiters"
+ default 4
+ depends on !DISABLE_POLL
+ ---help---
+ The maximum number of threads that may be waiting on the poll method.
