From d560225fc4c3b75e65665df503c0641e3030bd08 Mon Sep 17 00:00:00 2001 From: Anton Johansson Date: Tue, 12 Sep 2023 17:34:23 +0200 Subject: [PATCH] accel/tcg: Modify atomic_mmu_lookup() to use CPUState MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The goal is to (in the future) allow for per-target compilation of functions in atomic_template.h whilst atomic_mmu_lookup() and cputlb.c are compiled once-per user- or system mode.
