[PATCH 0/5] kselftest/arm64: add features check to hwcap test

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

 



Add new feature checks and provide testing item to support capturing
SIGBUS exception signal.

The following is a log snippet from my local testing environment:
