Subject: [PATCH] KVM: arm64: Update kvm_arm_exception_class and esr_class_str for new EC
Date: Sat, 13 Jul 2019 04:40:54 +0000 [thread overview]
Message-ID: <1562992854-972-1-git-send-email-yuzenghui@huawei.com> (raw)
We've added two ESR exception classes for new ARM hardware extensions:
ESR_ELx_EC_PAC and ESR_ELx_EC_SVE.
This patch updates "kvm_arm_exception_class" for these two EC, which the
new EC will be parsed in kvm_exit trace events (for guest's usage of
Pointer Authentication and Scalable Vector Extension). The same updates
to "esr_class_str" for ESR_ELx_EC_PAC, by which we can get more accurate
debug info. Trivial changes, update them in one go.
