Subject: [PATCH] arm64: KVM: Force undefined exception for Guest SMC intructions
Date: Thu, 12 Dec 2013 21:42:23 +0530 [thread overview]
Message-ID: <1386864747-29006-2-git-send-email-anup.patel@linaro.org> (raw)
In-Reply-To: <1386864747-29006-1-git-send-email-anup.patel@linaro.org>
The SMC-based PSCI emulation for Guest is going to be very different
from the in-kernel HVC-based PSCI emulation hence for now just inject
undefined exception when Guest executes SMC instruction.
