Using the general purpose "debug" and "verbose" kernel parameters to increase logging in the init script has the disadvantage that it also increases logging in other components, making the output hard to read (in particular with "debug").
The new init_verbose parameter only affects the init script: init_verbose, init_verbose=1, init_verbose=true: enable just some info messages init_verbose=2: debug messages Signed-off-by: Patrick Ohly <[email protected]> --- meta/recipes-core/initrdscripts/initramfs-framework/init | 16 ++++++++++++++-- 1 file changed, 14 insertions(+), 2 deletions(-) diff --git a/meta/recipes-core/initrdscripts/initramfs-framework/init b/meta/recipes-core/initrdscripts/initramfs-framework/init index e8f4713..cd55ee2 100755 --- a/meta/recipes-core/initrdscripts/initramfs-framework/init +++ b/meta/recipes-core/initrdscripts/initramfs-framework/init @@ -14,6 +14,13 @@ # 'foo=value' as 'bootparam_foo=value' # 'foo' as 'bootparam_foo=true' # 'foo.bar[=value] as 'foo_bar=[value|true]' +# +# Special boot parameters always recognized by initramfs-framework (see modules +# like "debug" for additional ones): +# debug: enable debug logging (beware, also enables debug output in other system components) +# verbose: similar do debug, just less output +# init_verbose[=true|1|2]: same output as for verbose when no value or true/1 are given, +# same as debug for 2 - only affects logging in initramfs-framework # Register a function to be called before running a module # The hook is called as: @@ -45,12 +52,12 @@ msg() { # Prints information if verbose bootparam is used info() { - [ -n "$bootparam_verbose" ] && echo "$@" >/dev/console + ( [ -n "$bootparam_verbose" ] || [ "${bootparam_init_verbose:-0}" -gt 0 ] ) && echo "$@" >/dev/console } # Prints information if debug bootparam is used debug() { - [ -n "$bootparam_debug" ] && echo "DEBUG: $@" >/dev/console + ( [ -n "$bootparam_debug" ] || [ "${bootparam_init_verbose:-0}" -gt 1 ] ) && echo "DEBUG: $@" >/dev/console } # Prints a message and start a endless loop @@ -89,6 +96,11 @@ for p in `cat /proc/cmdline`; do fi done +# Simplify log level check in debug() and info(). +if [ "x$bootparam_init_verbose" = "xtrue" ]; then + bootparam_init_verbose=1 +fi + # use /dev with devtmpfs if grep -q devtmpfs /proc/filesystems; then mkdir -p /dev -- 2.1.4 -- _______________________________________________ Openembedded-core mailing list [email protected] http://lists.openembedded.org/mailman/listinfo/openembedded-core
