Re: [alsa-devel] No sound with nVidia Corporation MCP79 High Definition Audio (rev b1) (Macbook Pro 5, 5)
by Sean Burke 03 Jul '09

A quick google shows that the vendor ID is Cirrus Logic. The Boot Camp driver set does include installers for Cirrus audio cards. I don't have Windows installed on here, so I can't check to see if it is indeed the Cirrus drivers that get installed. What can be done to facilitate the implementation of this codec? Sean

[alsa-devel] [PATCH] ASoC: Fix wm8753 register cache size and initialization
by Lars-Peter Clausen 03 Jul '09

03 Jul '09

The register cache size is of by one. There are 63 registers in use but the register cache size has only space for 62. Furthermore the codec's reg_cache_size is of by another one. Since the wm8753 register cache uses one-based indexing we have to add one to its size. Register cache initialization only copied the first sizeof(void*) elements leaving the others uninitialized. Fix it by using the size of the reg cache template.

[alsa-devel] [PATCH] ASoC: Zoom2: Update twl4030_setup_data parameters
by Candelaria Villareal, Jorge 03 Jul '09

03 Jul '09

Add support for EXTMUTE in Zoom2 machine driver. This is necessary to further reduce pop noise problem. Signal EXTMUTE is connected to signal GPIO 153 in Zoom2 board. In addition, change ramp delay value to 3 (218/161/109 ms). With previous ramp delay value, pop noise was louder. With a longer value the beep tone can be observed.

[alsa-devel] [PATCH] [RFC 7/13] Intel SST driver stream module
by Vinod Koul 03 Jul '09

03 Jul '09

This adds the stream module which contains the function for stream operations & control. 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 Firmware. The objective of SST driver is to achieve Low power playback by utilizing DSP as much as possible. So SST gets large music buffers from player/middleware and sends them to firmware in a scatter gather list. The firmware decodes and renders them, while IA can goto low power states Signed-off-by: Vinod Koul <vinod.koul(a)intel.com> Signed-off-by: Harsha Priya <priya.harsha(a)intel.com> Signed-off-by: R Dharageswari <dharageswari.r(a)intel.com> new file: sound/pci/sst/intel_sst_stream.c --- sound/pci/sst/intel_sst_stream.c | 711 ++++++++++++++++++++++++++++++++++++++ 1 files changed, 711 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..aabf057 --- /dev/null +++ b/sound/pci/sst/intel_sst_stream.c @@ -0,0 +1,711 @@ +/* + * intel_sst_stream.c - Intel SST Driver for audio engine + * + * Copyright (C) 2008-09 Intel Corp + * Authors: Vinod Koul <vinod.koul(a)intel.com> + * Harsha Priya <priya.harsha(a)intel.com> + * R Dharageswari <dharageswari.r(a)intel.com> + * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + * + * 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.

[alsa-devel] [PATCH] [RFC 6/13] Intel SST driver dsp engine interface module
by Vinod Koul 03 Jul '09

03 Jul '09

This adds the IPC module which uses Inter process mechanism to communicate between driver & SST engine (DSP processor). To communicate between IA processor and DSP, IPC doorbell registers are used. A write to these registers triggers an interrupt to other side. The format of messages and "mailbox" for message payload is defined in intel_lpe_fw_ipc.h Signed-off-by: Vinod Koul <vinod.koul(a)intel.com> Signed-off-by: Harsha Priya <priya.harsha(a)intel.com> new file: sound/pci/sst/intel_sst_fw_ipc.h new file: sound/pci/sst/intel_sst_ipc.c --- sound/pci/sst/intel_sst_fw_ipc.h | 368 ++++++++++++++++++++++++++ sound/pci/sst/intel_sst_ipc.c | 536 ++++++++++++++++++++++++++++++++++++++ 2 files changed, 904 insertions(+), 0 deletions(-) create mode 100644 sound/pci/sst/intel_sst_fw_ipc.h create mode 100644 sound/pci/sst/intel_sst_ipc.c diff --git a/sound/pci/sst/intel_sst_fw_ipc.h b/sound/pci/sst/intel_sst_fw_ipc.h new file mode 100644 index 0000000..6520e4e --- /dev/null +++ b/sound/pci/sst/intel_sst_fw_ipc.h @@ -0,0 +1,368 @@ +#ifndef __INTEL_SST_FW_IPC_H__ +#define __INTEL_SST_FW_IPC_H__ +/* +* intel_sst_fw_ipc.h - Intel SST Driver for audio engine +* +* Copyright (C) 2008-09 Intel Corporation +* Author: Vinod Koul <vinod.koul(a)intel.com> +* Harsha Priya <priya.harsha(a)intel.com> +* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +* +* 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.

[alsa-devel] [PATCH] [RFC 11/13] Intel SST sound card vendor2 module
by Vinod Koul 03 Jul '09

03 Jul '09

This adds the support for vendor PMICs for widget control and configurations. The MID platform supports three different vendor implementation of PMIC. The sound card, ie all analog components like DAC, ADC, mixer settings are different for three vendors. This patch implements these settings for one of the vendor Signed-off-by: Vinod Koul <vinod.koul(a)intel.com> Signed-off-by: Harsha Priya <priya.harsha(a)intel.com> Signed-off-by: R Dharageswari <dharageswari.r(a)intel.com> new file: sound/pci/sst/intelmid_v2_control.c --- sound/pci/sst/intelmid_v2_control.c | 629 +++++++++++++++++++++++++++++++++++ 1 files changed, 629 insertions(+), 0 deletions(-) create mode 100644 sound/pci/sst/intelmid_v2_control.c diff --git a/sound/pci/sst/intelmid_v2_control.c b/sound/pci/sst/intelmid_v2_control.c new file mode 100644 index 0000000..21e3cdb --- /dev/null +++ b/sound/pci/sst/intelmid_v2_control.c @@ -0,0 +1,629 @@ +/* + * intelmid_v2_control.c - Intel Sound card driver for MID + * + * Copyright (C) 2008-09 Intel Corp + * Authors: Vinod Koul <vinod.koul(a)intel.com> + * Harsha Priya <priya.harsha(a)intel.com> + * R Dharageswari <dharageswari.r(a)intel.com> + * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + * + * 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.
