From 8cfb4937af9b214e9855b10dd9bac291bca263b8 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20L=C3=BCtke-Stetzkamp?= Date: Wed, 18 Apr 2018 17:27:43 +0200 Subject: [PATCH] staging: mt7621-mmc: Change default transfer mode to DMA MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The current default transfer is to use DMA or not depending on the size of the data. The upstream driver mtk-sd uses DMA all times, change the standard mode here to DMA for testing, if there are any performance problems with DMA for small data sizes. If not, the option for transfer mode should be removed in the future, Signed-off-by: Christian Lütke-Stetzkamp Signed-off-by: Greg Kroah-Hartman --- drivers/staging/mt7621-mmc/dbg.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/staging/mt7621-mmc/dbg.c b/drivers/staging/mt7621-mmc/dbg.c index 9a1809d74ea31..0d6e21557d8f5 100644 --- a/drivers/staging/mt7621-mmc/dbg.c +++ b/drivers/staging/mt7621-mmc/dbg.c @@ -67,10 +67,10 @@ u32 dma_size[4] = { }; enum msdc_mode drv_mode[4] = { - MODE_SIZE_DEP, /* using DMA or not depend on the size */ - MODE_SIZE_DEP, - MODE_SIZE_DEP, - MODE_SIZE_DEP + MODE_DMA, /* using DMA always */ + MODE_DMA, + MODE_DMA, + MODE_DMA }; #if defined(MT6575_SD_DEBUG) -- 2.30.2
