[PATCH v6 01/11] sysemu/tcg: Introduce tcg_builtin() helper


From: Philippe Mathieu-Daudé
Subject: [PATCH v6 01/11] sysemu/tcg: Introduce tcg_builtin() helper
Date: Sun, 31 Jan 2021 12:50:12 +0100

Modules are registered early with type_register_static().

We would like to call tcg_enabled() when registering QOM types,
but tcg_enabled() returns tcg_allowed which is a runtime property
initialized later (See commit 2f181fbd5a9 which introduced the
MachineInitPhase in "hw/qdev-core.h" representing the different
phases of machine initialization and commit 0427b6257e2 which
document the initialization order).

As we are only interested if the TCG accelerator is builtin,
regardless of being enabled, introduce the tcg_builtin() helper.
