Subject: [PATCH v2 17/18] target/riscv/kvm.c: add kvmconfig_get_cfg_addr() helper
Date: Tue, 13 Jun 2023 17:58:56 -0300 [thread overview]
Message-ID: <20230613205857.495165-18-dbarboza@ventanamicro.com> (raw)
In-Reply-To: <20230613205857.495165-1-dbarboza@ventanamicro.com>
There are 2 places in which we need to get a pointer to a certain
property of the cpu->cfg struct based on property offset. Next patch
will add a couple more.
Create a helper to avoid repeating this code over and over.
