Subject: [Patch 5/6] MIPS: Scheduler support for HARDWARE_WATCHPOINTS.
Date: Thu, 28 Aug 2008 15:11:57 -0700 [thread overview]
Message-ID: <48B722AD.3000703@avtrex.com> (raw)
In-Reply-To: <48B71ADD.601@avtrex.com>
Here we hook up the scheduler. Whenever we switch to a new process,
we check to see if the watch registers should be installed, and do it
if needed.
