From ae08fd5a365e650d70acfe1d9027501707041b52 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Mon, 15 Jun 2015 14:35:58 +0200 Subject: qemu-options: Improve -global documentation Recent commit 3751d7c "vl: allow full-blown QemuOpts syntax for -global" overloaded its existing argument syntax DRIVER.PROP=VALUE with QemuOpts syntax. Unambigious as long as no DRIVER contains '='. Its documentation claims that "the two syntaxes are equivalent." Improve it to spell out how exactly the old syntax gets desugared into the new one.
