Subject: [PATCH v10 16/19] RISC-V: KVM: Implement ONE REG interface for FP registers
Date: Mon, 23 Dec 2019 11:37:24 +0000 [thread overview]
Message-ID: <20191223113443.68969-17-anup.patel@wdc.com> (raw)
In-Reply-To: <20191223113443.68969-1-anup.patel@wdc.com>
From: Atish Patra <atish.patra@wdc.com>
Add a KVM_GET_ONE_REG/KVM_SET_ONE_REG ioctl interface for floating
point registers such as F0-F31 and FCSR. This support is added for
both 'F' and 'D' extensions.
