[alsa-devel] [RFC] ASoC: Intel: skl_hda_dsp_common: set long name for skl_hda_card
by Rander Wang 21 May '19

21 May '19

skl_hda_generic machine driver is used by many different devices and userspace uses the card long name to differentiate devices. The card long name is figured out by DMI info and is in format of "vendor-product-version-board". Ucm file is searched by this card long name and one problem is different devices can't share one ucm file based on this type of long name. We have three different product devices with the same codecs and audio settings, and these devices can share the same ucm setting, but now we need to provide three ucm files with different long names, because we can't get a same long name from DMI info. The solution is to provide card long name in machine driver like bytcr_rt5640 and ASoC will use this long name to generate final long name. The card long name is composed of codec name, input and output enabled by devices. The long name should be initialized after hda codec is initialized and before sound card checking long name which is done after dai link initialization, so the long name is set in codec dai link initialization function. Possible card long names may be: skl-hda-ALC233-config135440 skl-hda-ALC700-config69649 skl-hda-ALC3204-config135185 Tested on intel hda platform whiskylake with SOF driver and gemilake with intel SST driver Signed-off-by: Rander Wang <rander.wang(a)linux.intel.com> --- sound/soc/intel/boards/skl_hda_dsp_common.c | 54 +++++++++++++++++++++++++++++ 1 file changed, 54 insertions(+) diff --git a/sound/soc/intel/boards/skl_hda_dsp_common.c b/sound/soc/intel/boards/skl_hda_dsp_common.c index 8b68f41a5b88..0193d2138e16 100644 --- a/sound/soc/intel/boards/skl_hda_dsp_common.c +++ b/sound/soc/intel/boards/skl_hda_dsp_common.c @@ -11,11 +11,18 @@ #include <sound/pcm.h> #include <sound/pcm_params.h> #include <sound/soc.h> +#include <sound/hda_codec.h> +#include "../../../pci/hda/hda_jack.h" +#include "../../../pci/hda/hda_local.h" +#include "../../../pci/hda/hda_auto_parser.h" +#include "../../../pci/hda/hda_generic.h" #include "../../codecs/hdac_hdmi.h" +#include "../../codecs/hdac_hda.h" #include "../skylake/skl.h" #include "skl_hda_dsp_common.h" #define NAME_SIZE 32 +static char skl_hda_long_name[NAME_SIZE]; int skl_hda_hdmi_add_pcm(struct snd_soc_card *card, int device) { @@ -39,6 +46,52 @@ int skl_hda_hdmi_add_pcm(struct snd_soc_card *card, int device) return 0; } +int skl_hda_long_name_init(struct snd_soc_pcm_runtime *rtd) +{ + struct snd_soc_rtdcom_list *new_rtdcom; + struct snd_soc_component *component; + struct hdac_hda_priv *hda_pvt; + struct auto_pin_cfg *autocfg; + struct hda_gen_spec *spec; + struct snd_soc_card *card; + const char *name; + int config; + + name = rtd->dai_link->codecs->name; + card = rtd->card; + + list_for_each_entry(new_rtdcom, &rtd->component_list, list) { + component = new_rtdcom->component; + if (name && strcmp(component->name, name) == 0) { + hda_pvt = snd_soc_component_get_drvdata(component); + + if (!hda_pvt) + return -EINVAL; + + spec = hda_pvt->codec.spec; + autocfg = &spec->autocfg; + + /* + * config is figured out by combining the number of + * enabled input and output. + */ + config = autocfg->speaker_outs | (autocfg->hp_outs << 4) + | (autocfg->dig_outs << 8) + | (autocfg->line_outs << 12) + | (autocfg->num_inputs << 16); + snprintf(skl_hda_long_name, sizeof(skl_hda_long_name), + "skl-hda-%s-config%d", + hda_pvt->codec.core.chip_name, + config); + + card->long_name = skl_hda_long_name; + break; + } + } + + return 0; +} + /* skl_hda_digital audio interface glue - connects codec <--> CPU */ struct snd_soc_dai_link skl_hda_be_dai_links[HDA_DSP_MAX_BE_DAI_LINKS] = { /* Back End DAI links */ @@ -79,6 +132,7 @@ struct snd_soc_dai_link skl_hda_be_dai_links[HDA_DSP_MAX_BE_DAI_LINKS] = { .dpcm_playback = 1, .dpcm_capture = 1, .no_pcm = 1, + .init = skl_hda_long_name_init, }, { .name = "Digital Playback and Capture", -- 2.14.1

[alsa-devel] [PATCH - alsa-lib 3/4] pcm: add mmap_begin callback to snd_pcm_fast_ops_t api
by Adam Miartus 21 May '19

21 May '19

main motivation for adding the callback is to use it to enable operation on mmaped buffer before user access for pcm_file plugin support for MMAP read access with masking by data from input file is not implemented for pcm_file plugin, by adding this callback implementing such feature can be done by rewriting next continuous portion of buffer on each mmap_begin call plugins like softvol use pcm_plugin interface and overwrite the buffer by looping around it in avail_update callback, this patch hopes to simplify the task by adding new api callback, removing the need for rewriting pcm_file (to use pcm_plugin callbacks) and careful checking when looping around whole mmaped buffer Signed-off-by: Adam Miartus <amiartus(a)de.adit-jv.com> Reviewed-by: Timo Wischer <twischer(a)de.adit-jv.com> diff --git a/src/pcm/pcm.c b/src/pcm/pcm.c index 3a71d79..323926e 100644 --- a/src/pcm/pcm.c +++ b/src/pcm/pcm.c @@ -7129,7 +7129,13 @@ int __snd_pcm_mmap_begin(snd_pcm_t *pcm, const snd_pcm_channel_area_t **areas, snd_pcm_uframes_t f;
