Subject: [PATCH] docs/tcg-plugins: document QEMU_PLUGIN behaviour
Date: Wed, 16 Mar 2022 13:40:12 +0100 [thread overview]
Message-ID: <20220316124012.1413954-1-cmuellner@linux.com> (raw)
QEMU plugins can be loaded via command line arguments or via
the QEMU_PLUGIN environment variable. Currently, only the first method
is documented. Let's document QEMU_PLUGIN.
