From mboxrd@z Thu Jan 1 00:00:00 1970 From: Anup Patel Date: Wed, 20 Sep 2023 21:16:05 +0530 Subject: [PATCH v2 1/4] RISC-V: KVM: Fix KVM_GET_REG_LIST API for ISA_EXT registers In-Reply-To: <20230920154608.1447057-1-apatel@ventanamicro.com> References: <20230920154608.1447057-1-apatel@ventanamicro.com> Message-ID: <20230920154608.1447057-2-apatel@ventanamicro.com> List-Id: To: kvm-riscv@lists.infradead.org MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit The ISA_EXT registers to enabled/disable ISA extensions for VCPU are always available when underlying host has the corresponding ISA extension. The copy_isa_ext_reg_indices() called by the KVM_GET_REG_LIST API does not align with this expectation so let's fix it.
