Subject: [PATCH 1/6] RISC-V: KVM: Set initial value of hedeleg in kvm_arch_vcpu_create()
Date: Thu, 14 Aug 2025 21:25:43 +0530 [thread overview]
Message-ID: <20250814155548.457172-2-apatel@ventanamicro.com> (raw)
In-Reply-To: <20250814155548.457172-1-apatel@ventanamicro.com>
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().
