Subject: [PATCH v2 17/19] KVM: arm64: selftests: Add physical timer registers to the sysreg list
Date: Mon, 13 Mar 2023 12:48:35 +0000	[thread overview]
Message-ID: <20230313124837.2264882-18-maz@kernel.org> (raw)
In-Reply-To: <20230313124837.2264882-1-maz@kernel.org>

Now that KVM exposes CNTPCT_EL0, CNTP_CTL_EL0 and CNT_CVAL_EL0 to
userspace, add them to the get-reg-list selftest.
