From 33edcde7c8e0a94e93dc4fcc47b70e8f90891581 Mon Sep 17 00:00:00 2001 From: Daniel Henrique Barboza Date: Wed, 2 Mar 2022 06:51:36 +0100 Subject: [PATCH] target/ppc: make power8-pmu.c CONFIG_TCG only MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This is an exclusive TCG helper. Gating it with CONFIG_TCG and changing meson.build accordingly will prevent problems --disable-tcg and --disable-linux-user later on. We're also changing the uses of !kvm_enabled() to tcg_enabled() to avoid adding "defined(CONFIG_TCG)" ifdefs, since tcg_enabled() will be defaulted to false with --disable-tcg and the block will always be skipped.
