Subject: [PATCH 4/4] target/ppc: Use probe_write for DCBZ
Date: Wed, 29 Jan 2020 15:50:40 -0800 [thread overview]
Message-ID: <20200129235040.24022-5-richard.henderson@linaro.org> (raw)
In-Reply-To: <20200129235040.24022-1-richard.henderson@linaro.org>
Using probe_write instead of tlb_vaddr_to_host means that we
process watchpoints and notdirty pages more efficiently.
