[alsa-devel] snd_seq_parse_address matching prefix
by Henning Thielemann 14 Mar '12

14 Mar '12

snd_seq_parse_address(seq, addr, "foo") does not look for a client named "foo" but for a client with prefix "foo". I always found this to be a feature, not a bug, although it is not documented. Is this behavior intended? If yes, how to cope with the case where one client's name is the prefix of another one? E.g. let the clients be "foobar" "foo" (in this order) then parsing "foo" will return the client address of "foobar", not that of "foo". Even more there is no prefix that will select "foo", but not "foobar". Sorting the clients with respect to increasing name lengths and then searching for matching prefixes in the sorted list would solve that problem. Currently it's only a theoretical problem but if that behavior is intended it should at least be documented. Using snd_seq_query_next_client everyone can write his own parse_address. We should only know about the theoretical problem.

[alsa-devel] Clean up of PCM spinlocks
by Takashi Iwai 14 Mar '12

14 Mar '12

Hi, below is a patch I posted to LKML as the follow up for the lockdep report from Dave Jones. It's a resurrected patch from what I worked on quite ago. Although this fix is suboptimal, I see no better way. If this looks OK, I'm going to queue it as a 3.4 material. thanks, Takashi === From: Takashi Iwai <tiwai(a)suse.de> Subject: [PATCH] ALSA: pcm - Simplify linked PCM substream spinlocks The spinlocks held for PCM substreams have been always messy. For the better concurrent accessibility, we took always the substream's lock first. When substreams are linked, we need a group-wide lock, but this should be applied outside substream's lock. So, we unlock the substream's lock first, then do locks twice. This scheme is known to be problematic with lockdep. Maybe because the nested lock isn't marked properly, and partly because the lock and unlock sequences are different (A/B -> A/B). This patch tries to simplify the scheme. Instead of holding the substream's lock, we take the group lock always at first. A drawback of this is that the access to the individual substream in a same group won't be allowed any longer. But, the code looks much easier, and likely less buggy. Note that the group lock is identical with the substream's lock initially before the substream is linked with others. So, in the case of non-linked PCM, the new code behaves exactly same as before.

[alsa-devel] [PATCH] ASoC: max98095: add jack detection
by Rhyland Klein 14 Mar '12

14 Mar '12

This change adds the logic to support using the jack detect mechanism built in to the codec to detect both when a jack was inserted and what type of jack is present. This change also supports the use of an external mechanism for headphone detection. If this mechanism exists, when the max98095_jack_detect function is called, the hp_jack is simply passed NULL. This change supports both simple headphones, powered headphones, microphones and headsets with both headphones and a mic.

In general there's a pretty enormous abstraction layer in here which probably isn't doing all that much if this stuff is internal to the audio subsystem - my overall feeling reading the code is that the abstraction layer should be removed as it's internal to this driver. > +static struct ux500_platform_drvdata platform_drvdata[UX500_NBR_OF_DAI] = { > + { > + .msp_i2s_drvdata = NULL, > + .fmt = 0, > + .slots = 1, > + .tx_mask = 0x01, > + .rx_mask = 0x01, > + .slot_width = 16, > + .playback_active = false, > + .capture_active = false, > + .configured = 0, > + .master_clk = UX500_MSP_INTERNAL_CLOCK_FREQ, > + }, This looks like it should be dynamically created by the platform device, not a static struct. > +static const char *stream_str(struct snd_pcm_substream *substream) > +{ > + if (substream->stream == SNDRV_PCM_STREAM_PLAYBACK) > + return "Playback"; > + else > + return "Capture"; > +} Don't add generic code in drivers. > + if (mode_playback) > + drvdata->playback_active = true; > + else > + drvdata->capture_active = true; All this mode_playback stuff is non-idiomatic. > +static void ux500_msp_dai_shutdown(struct snd_pcm_substream *substream, > + struct snd_soc_dai *dai) > +{ > + struct ux500_platform_drvdata *drvdata = &platform_drvdata[dai->id]; > + bool mode_playback = (substream->stream == SNDRV_PCM_STREAM_PLAYBACK); > + > + dev_dbg(dai->dev, "%s: MSP %d (%s): Enter.\n", __func__, dai->id, > + stream_str(substream)); > + > + if (drvdata == NULL) > + return; Why might that happen? > + prot_desc->total_clocks_for_one_frame = > + prot_desc->frame_period+1; > + > + dev_dbg(dai->dev, "%s: Total clocks per frame: %u\n", > + __func__, > + prot_desc->total_clocks_for_one_frame); This looks like your clock calculation stuff may be replicating framework features. > + switch (fmt & SND_SOC_DAIFMT_INV_MASK) { > + default: > + case SND_SOC_DAIFMT_NB_NF: > + break; > + > + case SND_SOC_DAIFMT_NB_IF: > + msp_config->tx_frame_sync_pol ^= 1 << TFSPOL_SHIFT; > + msp_config->rx_frame_sync_pol ^= 1 << RFSPOL_SHIFT; > + break; > + } Shold be returning an error for unsupported modes. > + if ((fmt & SND_SOC_DAIFMT_MASTER_MASK) == SND_SOC_DAIFMT_CBM_CFM) { > + dev_dbg(dai->dev, "%s: Codec is MASTER.\n", This should be a switch statement and again should error out on unsupporetd modes.

[alsa-devel] Triple implementation of WM8766 and quadruple WM8776!
by Ondrej Zary 13 Mar '12

13 Mar '12

Hello, I'm trying do implement support for Philips PSC724 Ultimate Edge card, which is based on VT1722 + WM8776 + WM8766 chips. Found that the best file to base my work on is sound/pci/ice1712/se.c (as SE-200PCI card contains both WM8776 and WM8766 chips). While doing this, found that there are three implementations of WM8766 codec control, two of them in the same driver(!): sound/pci/ice1712/se.c sound/pci/ice1712/prodigy_hifi.c sound/pci/oxygen/xonar_wm87x6.c (+sound/pci/oxygen/wm8766.h) And WM8776 status is even worse, there are four implementations, again two being in the same driver: sound/pci/ice1712/se.c sound/pci/ice1712/maya44.c sound/pci/oxygen/xonar_wm87x6.c (+sound/pci/oxygen/wm8776.h) sound/soc/codecs/wm8776.c (this one being official and stand-alone module but it does not seem to be usable as a part of sound card driver) My code would enlarge both of these lists and I don't like that. What to do? -- Ondrej Zary

[alsa-devel] [PATCH] ASoC: jack: Push locking for jacks down to the jack
by Mark Brown 13 Mar '12

13 Mar '12

Currently operations on jack reporting take the CODEC mutex both to protect the current jack status and also to protect the DAPM run which is triggered on status updates. Since the addition of a DAPM-specific lock we no longer need to worry about locking DAPM as it has its own finer grained lock so create a per jack lock to take care of the jack status. This is both cleaner where the jack isn't specifically associated with a CODEC and clearer as it's much more obvious what the lock is protecting.

[alsa-devel] [PATCH] ALSA: hda - fix printing of high HDMI sample rates
by Anssi Hannula 13 Mar '12

13 Mar '12

A previous commit af65cbf296 (ALSA: hdmi: fix printout of SAD sampling rates) fixed the sample rates shown in /proc/asound/cardX/eldY and kernel log to not be entirely wrong. However, a missing rate from the array added in the patch causes HDMI rates 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz to be shown as 96 kHz, 176.4 kHz, 192 kHz, and 384 kHz, respectively. Fix the reporting by adding the ALSA rate 64 kHz into the conversion array between 48 kHz and 88.2 kHz.
