From 057dc9a635fe37118a98b32e8bd9d8ed47b1a102 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Tue, 4 Jan 2022 11:33:19 +0100 Subject: docs/tools/qemu-trace-stap.rst: Do not hard-code the QEMU binary name MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In downstream, we want to use a different name for the QEMU binary, and some people might also use the docs for non-x86 binaries, that's why we already created the |qemu_system| placeholder in the past. Use it now in the stap trace doc, too.
