For a stream the control and data are two major parts. +This module implements the control (play/pause/resume/stop/free/alloc) +for a stream. It also implements data play/capture frames where buffers are +sent/received to FW. The objective of SST driver is to achieve Low power +playback by utilizing DSP as much aspossible. So SST gets large music +buffers from player/middleware and sends them to FW in a scatter gather list. +The FW decodes and renders them, while IA can goto low power states + +Signed-off-by: Vinod Koul + + new file: sound/pci/sst/intel_sst_stream.c +Patch-mainline: 2.6.35? +--- + sound/pci/sst/intel_sst_stream.c | 1658 ++++++++++++++++++++++++++++++++++++++ + 1 files changed, 1658 insertions(+), 0 deletions(-) + create mode 100644 sound/pci/sst/intel_sst_stream.c + +diff --git a/sound/pci/sst/intel_sst_stream.c b/sound/pci/sst/intel_sst_stream.c +new file mode 100644 +index 0000000..07a4e55 +--- /dev/null ++++ b/sound/pci/sst/intel_sst_stream.c +@@ -0,0 +1,1658 @@ ++/* ++ * intel_sst_stream.c - Intel SST Driver for audio engine ++ * ++ * Copyright (C) 2008-10 Intel Corp ++ * Authors: Vinod Koul ++ * Harsha Priya ++ * Dharageswari R ++ * KP Jeeja ++ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ++ * ++ * This program is free software; you can redistribute it and/or modify ++ * it under the terms of the GNU General Public License as published by ++ * the Free Software Foundation; version 2 of the License. ++ * ++ * This program is distributed in the hope that it will be useful, but ++ * WITHOUT ANY WARRANTY; without even the implied warranty of ++ * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
