[PATCH v4 4/7] target/mips: Add implementation of GINVT instruction |
|
Date: |
Fri, 24 Jan 2020 17:38:46 +0100 |
From: Yongbok Kim <address@hidden>
Implement emulation of GINVT instruction. As QEMU doesn't support
caches and virtualization, this implementation covers only GINVT
(Global Invalidate TLB) instruction among TLB-related instructions.
