Subject: [PATCH v2 04/18] arm64: KVM: add SPE system registers to sys_reg_descs
Date: Fri, 20 Dec 2019 14:30:11 +0000 [thread overview]
Message-ID: <20191220143025.33853-5-andrew.murray@arm.com> (raw)
In-Reply-To: <20191220143025.33853-1-andrew.murray@arm.com>
From: Sudeep Holla <sudeep.holla@arm.com>
Add the Statistical Profiling Extension(SPE) Profiling Buffer controls
registers such that we can provide initial register values and use the
sys_regs structure as a store for our SPE context.
Signed-off-by: Sudeep Holla <sudeep.holla@arm.com>
[ Reword commit, remove access/reset handlers, defer kvm_arm_support_spe_v1 ]
