Subject: [kvm-unit-tests PATCH v3 0/2] arm: MMU extentions to enable litmus7
Date: Tue, 10 Nov 2020 18:09:22 +0000 [thread overview]
Message-ID: <20201110180924.95106-1-nikos.nikoleris@arm.com> (raw)
Hi all,
litmus7 [1][2], a tool that we develop and use to test the memory
model on hardware, is building on kvm-unit-tests to encapsulate full
system tests and control address translation. This series extends the
kvm-unit-tests arm MMU API and adds two memory attributes to MAIR_EL1
to make them available to the litmus tests.
