[PATCH] arm: exynos increase CONFIG_CMA_SIZE_MBYTES to 96
From: Shuah Khan
Date: Mon Feb 27 2017 - 22:15:43 EST
Current CMA size of 64 Mbytes is right on the edge of being too small
for some display managers. With the proposed s5p_mfc patch series that
pre-allocate buffers, when display manager starts, it fails to get GEM
buffers. Increasing the CMA size to 96 solves the problem.
Change CONFIG_CMA_SIZE_MBYTES to 96 in exynos_defconfig to address the
problem.
