Subject: [PATCH v4 11/12] KVM: arm64: enable KVM_CAP_SET_GUEST_DEBUG
Date: Fri, 15 May 2015 15:27:14 +0100 [thread overview]
Message-ID: <1431700035-23479-12-git-send-email-alex.bennee@linaro.org> (raw)
In-Reply-To: <1431700035-23479-1-git-send-email-alex.bennee@linaro.org>
Finally advertise the KVM capability for SET_GUEST_DEBUG. Once arm
support is added this check can be moved to the common
kvm_vm_ioctl_check_extension() code.
Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
Acked-by: Christoffer Dall <christoffer.dall@linaro.org>

v3:
- separated capability check from previous patches
- moved into arm64 specific ioctl handler.
v4:
- add a-b-tag
