From 0386f39b46a28da87647075f0fc20da4ba1f6478 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Cl=C3=A9ment=20Chigot?= Date: Tue, 3 Oct 2023 09:14:23 +0200 Subject: [PATCH] softmmu: add means to pass an exit code when requesting a shutdown MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As of now, the exit code was either EXIT_FAILURE when a panic shutdown was requested or EXIT_SUCCESS otherwise. However, some hardware could want to pass more complex exit codes. Thus, introduce a new shutdown request function allowing that.
