Subject: [RFC PATCH 1/7] build: add debug menu to Kconfig
Date: Sun,  1 May 2016 23:10:40 -0500	[thread overview]
Message-ID: <1462162246-32413-2-git-send-email-cardoe@cardoe.com> (raw)
In-Reply-To: <1462162246-32413-1-git-send-email-cardoe@cardoe.com>

There are a number of debugging options for Xen so the idea is to have a
menu to group them all together. Enabling this menu item will also
disable NDEBUG which will result in more debug prints. This was
previously wired into the 'debug=y' command line option.
