Subject: [powerpc v4 0/3] Enable IAMR storage keys for radix
Date: Mon, 14 Nov 2016 16:25:09 +1100 [thread overview]
Message-ID: <1479101112-21120-1-git-send-email-bsingharora@gmail.com> (raw)
The first patch sets up AMOR in hypervisor mode. AMOR
needs to be setup before IAMR (details of AMOR/IAMR in
each patch). The second patch enables detection of exceptions
generated due to instruction fetch violations caused
and OOPSs' the task. The third patch enables IAMR for
both hypervisor and guest kernels.
I've tested with patch series with a sample hack and
payload.
Chris Smart helped with the series, reviewing and
providing valuable feedback
