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.

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_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.

config SYSLOG_CONSOLE
|
|
bool "Use SYSLOG for /dev/console"
|
|
default n
|
|
depends on DEV_CONSOLE
|
|
---help---
|
|
Use the syslog logging device as a system console. If this feature is enabled
|
|
(along with DEV_CONSOLE), then all console output will be re-directed to syslog
|
|
output (syslog_putc). 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 syslog output.

config DRIVER_NOTE
|
|
bool "Scheduler instrumentation driver"
|
|
default n
|
|
depends on SCHED_INSTRUMENTATION_BUFFER
|
|
---help---
|
|
Enable building a serial driver that can be used by an application to read data
|
|
from the in-memory, scheduler instrumentatin "note" buffer.
