From 89e74ed89899ac57c155b57b57682edd39fc8c48 Mon Sep 17 00:00:00 2001 From: Mohit Khanna Date: Sat, 6 May 2017 13:13:17 -0700 Subject: defconfig: msmcortex: Disable CONFIG_FORCE_ALLOC_FROM_DMA_ZONE This flag is primarily being used for WLAN to support WLAN hardware which cannot handle "> 32 bit" physical addresses for DMA. Disable this flag for the perf variant of msm8998. This flag forces DMA addresses to be in 32 bit region. Using this flag with ihelium WLAN solution (which can handle 64 bit physical DMA addresses) is causing a reduction in peak KPIs for TCP RX. Since kernel 4.4 is being used only by ihelium and not being used for older versions of WLAN hardware (e.g. ROME), we can safely disable this flag.
