Hi,
This is a series of patches to introduce scripts for the boot-time tracing.
- bconf2ftrace.sh generates a shell script from a bootconfig file which setup ftrace via tracefs. This is useful for checking whether your boot-time tracing bootconfig is working as you expected.
- ftrace2bconf.sh generates a bootconfig file from current ftrace setting. You can set up the ftrace manually and run a test on it before dump it to a bootconfig file. Note that some function-tracer/fgraph-tracer options are not supported by ftrace2bconf.sh, because the original wildcard expression has been lost during setup ftrace.
Also, this series improve the bootconfig command to increase usability.
- The bootconfig can format the bootconfig file without initrd. You don't need a dummy initrd anymore :) - The bootconfig command supports -l (format as a list) option which outputs the bootconfig as a key-value list, as same as /proc/bootconfig.
Thank you,
