X-Received-From: 2607:f8b0:400e:c05::241 Subject: [Qemu-devel] [PATCH v2 21/21] RISC-V Build Infrastructure X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Bastian Koppelmann , RISC-V Patches , Michael Clark , Palmer Dabbelt , Sagar Karandikar Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" X-Virus-Scanned: ClamAV using ClamSMTP This adds RISC-V into the build system enabling the following targets: - riscv32-softmmu - riscv64-softmmu - riscv32-linux-user - riscv64-linux-user This adds defaults configs for RISC-V, enables the build for the RISC-V CPU core, hardware, and Linux User Emulation. The 'qemu-binfmt-conf.sh' script is updated to add the RISC-V ELF magic.
