[Qemu-devel] [PATCH] riscv: virt: Add cpu-topology DT node.

2019-06-24 Thread Atish Patra
Currently, there is no cpu topology defined in RISC-V. Define a device tree node that clearly describes the entire topology. This saves the trouble of scanning individual cache to figure out the topology. Here is the linux kernel patch series that enables topology for RISC-V.
