Subject: [PATCH 0/2] MTE support for KVM guest
Date: Mon, 13 Jul 2020 11:01:00 +0100	[thread overview]
Message-ID: <20200713100102.53664-1-steven.price@arm.com> (raw)

These patches add support to KVM to enable MTE within a guest. They are
based on Catalin's v6 MTE user-space support series[1]. Changes since
the previous RFC posting[2]:

* Correctly read/write TFSR_EL1 using {read,write}_sysreg_el1()
* Set SCTLR_EL2.ITFSB bit for non-VHE
* Minor updates to deal with rebasing
