Subject: [RFC PATCH 0/2] powerpc/64s: scv support
Date: Thu, 30 Apr 2020 14:02:00 +1000 [thread overview]
Message-ID: <20200430040202.1735506-1-npiggin@gmail.com> (raw)
Another round of scv, which is getting closer to done. ABI and
compatibility / feature testing still not set in stone, but some
good discussion among the various libcs etc. and it's close enough
that changes should just be small tweaks to clobbers etc. Posting
now because there is some interest to prototype userspace support
which we should do before fixing the ABI.
This relies on some of the signal handling and kuap patches I
already posted, so tree is here:
https://github.com/npiggin/linux/commits/next-test
I have qemu scv support apatches I need to resend, but they're not
merged yet. POWER9 system simulator should support it, but I have
not tested the public version:

Thanks,
