[PATCH v3 1/6] RISC-V: KVM: Set initial value of hedeleg in kvm_arch_vcpu_create()
Posted by Anup Patel 1 month, 1 week ago
The hedeleg may be updated by ONE_REG interface before the VCPU
is run at least once hence set the initial value of hedeleg in
kvm_arch_vcpu_create() instead of kvm_riscv_vcpu_setup_config().
