…conky Conky is a light-weight system monitor that can be easily customized with lua scripts. This adds a module that can be directly loaded via conky.conf and be used to display information about current usage of boards controlled by cdba. Put the script under a new directory: contrib/. It'll be used to store misc files that don't fit anywhere else. Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@oss.qualcomm.com>

System-specific details. Also cdba might be using a central db (/etc/cdba) instead.

Any suggestion on how to handle that?

Use posix.getpwnam to locate cdba's home dir. If ~cdba/.cdba doesn't exist, resort to /etc/cdba.

Would it be easier to use luaflock instead of parsing /proc/locks?

No, that requires CAP_SYS_PTRACE, my solution does not as it uses info available to an unprivileged user.

Conky is a light-weight system monitor that can be easily customized with lua scripts.
I'm running my cdba lab with a small display using conky to display system information. I wrote this lua script that uses the information about the cdba lock files and the cdba config to determine which boards are being used and for how long.
It can be easily integrated into conky.conf like so:
I figured it may be useful to others and it makes sense to carry it in the cdba repo.
