Subject: [Qemu-devel] [PATCH 7/9] target/xtensa: implement block prefetch option opcodes
Date: Tue, 14 May 2019 13:44:45 -0700	[thread overview]
Message-ID: <20190514204447.17486-8-jcmvbkbc@gmail.com> (raw)
In-Reply-To: <20190514204447.17486-1-jcmvbkbc@gmail.com>

Block prefetch option adds a bunch of non-privileged opcodes that may be
implemented as nops since QEMU doesn't model caches.
