From bb04aa6f7e40eb92688d5d21f15ada23924f17cb Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Fri, 23 Jan 2015 13:51:30 -0300 Subject: [PATCH] [media] coda: switch BIT decoder source queue to vmalloc Since we have to copy from input buffers into the bitstream ringbuffer with the CPU, there is no need for contiguous DMA buffers on the decoder input side.
