[Sound-open-firmware] [PATCH 1/4] [RFC]DMIC: Add PDM microphones (DMIC) support to DAI
by Seppo Ingalsuo 07 May '18

07 May '18

This patch adds the DMIC audio capture driver for SOF DAI component use. The DMIC feature allows to directly attach one to (typically) four PDM digital microphones into Intel SoC without a separate codec IC. This is supported by APL and most successor platforms. Corresponding patches are needed for kernel driver and topology to enable this feature. Tested in APL UP squared board without connected microphones SOF git master 3ad69eb715a09de9a0b91c56c9cca8a79ead00a9 Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo(a)linux.intel.com> --- configure.ac | 6 + src/audio/dai.c | 5 + src/drivers/Makefile.am | 6 +- src/drivers/dmic.c | 1331 +++++++++++++++++++++++++++++++++++++++++++++++ src/include/sof/dmic.h | 318 +++++++++++ src/include/sof/io.h | 8 + src/include/sof/trace.h | 3 +- src/include/uapi/ipc.h | 61 ++- 8 files changed, 1734 insertions(+), 4 deletions(-) create mode 100644 src/drivers/dmic.c create mode 100644 src/include/sof/dmic.h diff --git a/configure.ac b/configure.ac index d67c154..49e58a5 100644 --- a/configure.ac +++ b/configure.ac @@ -44,6 +44,12 @@ if test "$have_rimage" = "yes"; then fi AM_CONDITIONAL(BUILD_RIMAGE, test "$have_rimage" = "yes") +# Disable DMIC driver if requested, by default build for supported platforms +AC_ARG_ENABLE([dmic], AS_HELP_STRING([--disable-dmic], [Disable DMIC driver])) +AS_IF([test "x$enable_dmic" != "xno"], [ + AC_DEFINE([CONFIG_DMIC], [1], [Configure to build DMIC driver]) +]) + # Architecture support AC_ARG_WITH([arch], AS_HELP_STRING([--with-arch], [Specify DSP architecture]), diff --git a/src/audio/dai.c b/src/audio/dai.c index 7905665..1eeecd2 100644 --- a/src/audio/dai.c +++ b/src/audio/dai.c @@ -639,6 +639,11 @@ static int dai_config(struct comp_dev *dev, struct sof_ipc_dai_config *config) break; } break; + case SOF_DAI_INTEL_DMIC: + /* TODO: No hardwired values here. */ + dd->config.burst_elems = 2; + dev->frame_bytes = 8; + break; default: /* other types of DAIs not handled for now */ trace_dai_error("de2"); diff --git a/src/drivers/Makefile.am b/src/drivers/Makefile.am index 99232a3..5d0c5b3 100644 --- a/src/drivers/Makefile.am +++ b/src/drivers/Makefile.am @@ -13,12 +13,14 @@ endif if BUILD_APOLLOLAKE libdrivers_a_SOURCES += \ - hda-dma.c + hda-dma.c \ + dmic.c endif if BUILD_CANNONLAKE libdrivers_a_SOURCES += \ - hda-dma.c + hda-dma.c \ + dmic.c endif libdrivers_a_CFLAGS = \ diff --git a/src/drivers/dmic.c b/src/drivers/dmic.c new file mode 100644 index 0000000..d6b623b --- /dev/null +++ b/src/drivers/dmic.c @@ -0,0 +1,1331 @@ +/* + * Copyright (c) 2017, Intel Corporation + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * * Redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer. + * * Redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in the + * documentation and/or other materials provided with the distribution. + * * Neither the name of the Intel Corporation nor the + * names of its contributors may be used to endorse or promote products + * derived from this software without specific prior written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" + * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE + * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE + * ARE DISCLAIMED.

[Sound-open-firmware] Introduce a module parameter to configure SOF driver debug output?
by Lin, Mengdong 03 May '18

03 May '18

Hi, Sorry for the long mail. The kernel debug message from SOF driver can help us to debug issues and CI to provide hints for failed test cases. But it will be too much to output all of debug message by default. So maybe we can try to manage SOF debug messages as drm does? DRM is kernel gfx subsystem and Intel i915 driver is based on it. drm defines a module parameter 'debug' for user to specify a debug mask when booting the kernel. The debug mask is a bit mask of different message categories. By setting a suitable mask, user or CI can make DRM driver output message of specified categories. Usually we use drm.debug=0x0e to get most important debug messages. Maybe SOF driver can use this method to configure its messages? If this is doable, we can do some RFC patch. Here is how drm defines its debug mode in drivers/gpu/drm/drm_drv.c: MODULE_PARM_DESC(debug, "Enable debug output, where each bit enables a debug category.\n" "\t\tBit 0 (0x01) will enable CORE messages (drm core code)\n" "\t\tBit 1 (0x02) will enable DRIVER messages (drm controller code)\n" "\t\tBit 2 (0x04) will enable KMS messages (modesetting code)\n" "\t\tBit 3 (0x08) will enable PRIME messages (prime code)\n" "\t\tBit 4 (0x10) will enable ATOMIC messages (atomic code)\n" "\t\tBit 5 (0x20) will enable VBL messages (vblank code)\n" "\t\tBit 7 (0x80) will enable LEASE messages (leasing code)"); module_param_named(debug, drm_debug, int, 0600); void drm_dev_printk(const struct device *dev, const char *level, unsigned int category, const char *function_name, const char *prefix, const char *format, ...) { struct va_format vaf; va_list args; if (category != DRM_UT_NONE && !(drm_debug & category)) return; va_start(args, format); vaf.fmt = format; vaf.va = &args; if (dev) dev_printk(level, dev, DRM_PRINTK_FMT, function_name, prefix, &vaf); ... } Then base on this, it defines macros for outputting of different categories: #define DRM_DEV_DEBUG(dev, fmt, args...) \ drm_dev_printk(dev, KERN_DEBUG, DRM_UT_CORE, __func__, "", fmt, \ ##args) #define DRM_DEBUG(fmt, ...) \ drm_printk(KERN_DEBUG, DRM_UT_CORE, fmt, ##__VA_ARGS__) #define DRM_DEV_DEBUG_DRIVER(dev, fmt, args...) \ drm_dev_printk(dev, KERN_DEBUG, DRM_UT_DRIVER, __func__, "", \ fmt, ##args) #define DRM_DEBUG_DRIVER(fmt, ...) \ drm_printk(KERN_DEBUG, DRM_UT_DRIVER, fmt, ##__VA_ARGS__) #define DRM_DEV_DEBUG_KMS(dev, fmt, args...) \ drm_dev_printk(dev, KERN_DEBUG, DRM_UT_KMS, __func__, "", fmt, \ ##args) Thanks Mengdong

And if this is doable, how can we define the categories: IPC, PCM, TOPOLOGY, VIRTIO, DEV, DRIVER? Then we may define some macro like: SND_SOF_DEBUG_IPC(dev, fmt, args...) SND_SOF_DEBUG_PCM(dev, fmt, args...) SND_SOF_DEBUG_TPLG(dev, fmt, args...) ... for topology ... And we can also define category for different levels: SND_SOF_INFO_IPC SND_SOF_WARN_IPC SND_SOF_ERR_IPC ... > > >drm defines a module parameter 'debug' for user to specify the DRM > >debug mode when booting the kernel > And adding my two cents to it. > DRM provides a sysfs as well to change the value of debug parameters at > runtime.

[Sound-open-firmware] [PATCH] topology: mirror alsa-lib definitions for mclk/bclk
by Pierre-Louis Bossart 30 Apr '18

30 Apr '18

ALSA-lib introduced new definitions to work around an logical inversion for master/slave definitions. see e.g. commit 3778a30bb00 ('ASoC: topology: Fix bclk and fsync inversion in set_link_hw_format()') Make sure clarifications are reflected in the topology files bclk/fsync slave -> codec_slave mclk slave -> codec_mclk_in This patch requires the use of the latest alsa-lib git master (v1.1.6 does not contain the relevant patches). This patch also requires an updated kernel.

Thanks, that can be ~/bin, I'll fix it. Or I could skip the install step in this script. That avoids needing to specify the path and still avoids a sudo. For my workflow that's find since I just want the topologies generated, would that be sufficient for others too? > > +make -j$(nproc) > > +make install > > +cd ../sof.git > >
