[Qemu-devel] [PATCH 9/9] target-mips: Add EVA support to P5600 |
Date: |
Tue, 6 Sep 2016 12:03:44 +0100 |
Add the Enhanced Virtual Addressing (EVA) feature to the P5600 core
configuration, along with the related Segmentation Control (SC) feature
and writable CP0_EBase.WG bit.
This allows it to run Malta EVA kernels.
