- Subject: kABI compability checking
I have investigated the kernel ABI compatibility checking. There are
some scripts at Red Hat that do this checking on the RPMs. However,
these scripts are probably not appropriate for development. The scripts
make a number of assumptions about environment (the build system) that
are unlikely to exist on most developers machine. The scripts check for
comptibility across all the various target architectures.
The core of the checking is to compare the Module.symvers file from
different builds. I have attached a simple-minded script to point out
these problems given two different kernel build directories. It will
need refinement.
