Subject: [PATCH 4/5] KVM: arm64: Update kvm_arm_exception_class and esr_class_str for new EC
Date: Wed, 31 Jul 2019 18:36:49 +0100 [thread overview]
Message-ID: <20190731173650.12627-5-maz@kernel.org> (raw)
In-Reply-To: <20190731173650.12627-1-maz@kernel.org>
From: Zenghui Yu <yuzenghui@huawei.com>
We've added two ESR exception classes for new ARM hardware extensions:
ESR_ELx_EC_PAC and ESR_ELx_EC_SVE, but failed to update the strings
used in tracing and other debug.
Let's update "kvm_arm_exception_class" for these two EC, which the
new EC will be visible to user-space via kvm_exit trace events
Also update to "esr_class_str" for ESR_ELx_EC_PAC, by which we can
get more readable debug info.
