[PATCH v2 i-g-t] igt/list-workarounds: Extend the script to Mesa

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Updated the list-workarounds script so that it
can parse Mesa directory if provided. Moved the
common code to a separate function to allow
reuse for both kernel and mesa.

The new command line is:
Usage: list-workarounds [options] path-to-kernel
       -k path-to-kernel -m path-to-mesa

The legacy usage is retained to avoid breaking
backwards compatibility. New parameters -k and
-m are added for the new behavior.

Either kernel or mesa or both paths can be specified.
If path-to-mesa is invalid, error is reported.
