>From 1e8c0757f37656273772ef0e53914c99ace9a5d0 Mon Sep 17 00:00:00 2001 From: Hari Kanigeri <[email protected]> Date: Thu, 26 Mar 2009 16:38:10 -0500 Subject: [PATCH] DSPBRIDGE: Add DSP_MMU_DEBUG
This patch enables to monitor the usage of DSP Virtual memory by printing the used memory region, free memory region, and the largest contiguous memory region.
