From d3b6e2706dbb7595cf4e5e59ffffe4528ee02517 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Mon, 30 Jan 2017 21:27:49 +0200 Subject: ARM: exynos_defconfig: Enable DYNAMIC_DEBUG and get rid of old ext3 DYNAMIC_DEBUG is quite useful for debugging kernels and should not cause noticeable performance regressions. It makes the kernel bigger (around 4%) but this difference should not impact typical developer and reference usage of this defconfig.

For example, if the s5p-mfc driver needs to pre-allocate CMA memory to decode a H.264 1080p video, then there won't be enough CMA memory left for other drivers, such as the exynos-drm driver that may need to allocate GEM buffers for the display manager. Increasing CMA size to 96 Mbytes in exynos_defconfig addresses use-cases such as these.
