Subject: [PATCH 2/8] ARM: etm: Don't limit tracing to only non-secure code.
Date: Mon, 14 Feb 2011 22:11:10 -0800 [thread overview]
Message-ID: <1297750276-12475-2-git-send-email-arve@android.com> (raw)
In-Reply-To: <1296701663-12168-1-git-send-email-arve@android.com>
On some systems kernel code is considered secure, and this code
already limits tracing to the kernel text segment which results
in no trace data.
