Subject: [PATCH 0/4] powerpc/64: syscalls in C
Date: Tue, 27 Aug 2019 13:30:05 +1000 [thread overview]
Message-ID: <20190827033010.28090-1-npiggin@gmail.com> (raw)
This hasn't been highly stress tested or tested all cases (like 32-bit
binaries, single stepping, etc.) but so far it's running stable doing
normal kernel development and microbenchmarks.
Thanks,
Nick
