Re: Kernel ABI Monitoring and toolchain support

["Guillermo E. Martinez" <guillermo.e.martinez@oracle.com>]

Hello guys,

On our side we are working on:

  * Gives the support  to extract the ABI for Linux kernel image 
  and Linux  kernel modules using the CFT backed in with
  libabigail tools.
  * Add support to compare packages with CTF debug format by using
  abipkgdiff and other related libabigail tools.

   * https://sourceware.org/pipermail/libabigail/2022q2/004340.html
   * https://sourceware.org/pipermail/libabigail/2022q2/004345.html

If you think that it could be a point to talk as part of your MC,  I can for sure
provides more details about it.

Thanks for your comments,
Guillermo
