From 6d6c9853a8484a22c3aaada5664b15afae1f31cd Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 10 Jan 2014 14:20:42 +0100 Subject: ALSA: Enable CONFIG_ZONE_DMA for smaller PCI DMA masks commit 80ab8eae70e51d578ebbeb228e0f7a562471b8b7 upstream. The PCI devices with DMA masks smaller than 32bit should enable CONFIG_ZONE_DMA. Since the recent change of page allocator, page allocations via dma_alloc_coherent() with the limited DMA mask bits may fail more frequently, ended up with no available buffers, when CONFIG_ZONE_DMA isn't enabled. With CONFIG_ZONE_DMA, the system has much more chance to obtain such pages.
