[PATCH 0/9] [RFC] store module metadata in .modinfo elf section

Posted by Gerd Hoffmann 2 years, 10 months ago

This patch series stores module metadata in a .modinfo elf section and
adds a utility to read it.  For now the utility just prints the meta
data.  The plan is to store this in some file and have qemu read it.

Background is that the hard-coded lists in util/module.c are somewhat
ugly and also wouldn't work very well with a large number of modules,
so I'm looking for something else.

Posting this now to collect feedback on the apprach.
Should I continue this?
Better ideas?
Other comments & suggestions?

take care,
  Gerd
