Anup Patel d47390ade4 target/riscv: Emulate TIME CSRs for privileged mode ... Currently, TIME CSRs are emulated only for user-only mode. This patch add TIME CSRs emulation for privileged mode. For privileged mode, the TIME CSRs will return value provided by rdtime callback which is registered by QEMU machine/platform emulation (i.e. CLINT emulation). If rdtime callback is not available then the monitor (i.e. OpenSBI) will trap-n-emulate TIME CSRs in software. We see 25+% performance improvement in hackbench numbers when TIME CSRs are not trap-n-emulated. Backports commit c695724868ce4049fd79c5a509880dbdf171e744 from qemu		2020-03-22 02:22:17 -04:00
