2013-04-04Revert "ALSA: hda - Allow power_save_controller option override DCAPS"Takashi Iwai1-3/+2
This reverts commit 6ab317419c62850a71e2adfd1573e5ee87d8774f. The commit [6ab317419c: ALSA: hda - Allow power_save_controller option override DCAPS] changed the behavior of power_save_controller so that it can override the driver capability. This assumed that this option is rarely changed dynamically unlike power_save option. Too naive. It turned out that the user-space power-management tool tries to set power_save_controller option to 1 together with power_save option without knowing what's actually doing. This enabled forcibly the runtime PM of the controller, which is known to be broken om many chips thus disabled as default. So, the only sane fix is to revert this commit again. It was intended to ease debugging/testing for runtime PM enablement, but obviously we need another way for it.

2012-09-13ALSA: hda - Allow to pass position_fix=0 explicitlyTakashi Iwai1-2/+8
Set the default value of position_fix -1, and allow user passing position_fix=0 explicitly to set the "auto" position-fix mode. Otherwise the auto mode may be switched to others like COMBO of VIACOMBO when the controller prefers it, thus user can't set the auto mode any longer. Also updated the documentation appropriately, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-07-03ALSA: hda - Remove beep_mode=2Takashi Iwai1-2/+1
The beep_mode=2 option was introduced to make the beep mixer controlling the beep input allocation/deallocation dynamically, so that a user can switch between HD-audio codec digital beep and the system beep only via mixer API. This was necessary because the keyboard driver took only the first input beep instance at that time. However, the recent keyboard driver already processes the multiple input instances, thus there is no point to keep this mode. Let's remove it.

2012-03-23Merge tag 'sound-3.4' of ↵Linus Torvalds1-1/+7
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull updates of sound stuff from Takashi Iwai: "Here is the first big update chunk of sound stuff for 3.4-rc1. In the common sound infrastructure, there are a few changes for dynamic PCM support (used in ASoC) and a few clean-ups. Majority of changes are found, as usual, in HD-audio and ASoC. Some highlights of HD-audio changes: - All the long-standing static quirk codes for Realtek codec were finally removed by fixing and extending the Realtek auto-parser. - The mute-LED control is standardized over all HD-audio codec drivers using the extended vmaster hook. - The vmaster slave mixer elements are initialized to 0dB as default so that the user won't be annoyed by the silent output after updates, e.g. due to the additions of new elements. - Other many fix-ups for the misc HD-audio devices. In the ASoC side, this is a very active release, including a quite a few framework enhancements. Some highlights: - Support for widgets not associated with a CODEC, an important part of the dynamic PCM framework. - A library factoring out the common code shared by dmaengine based DMA drivers contributed by Lars-Peter Clausen. This will save a lot of code and make it much easier to deploy enhancements to dmaengine. - Support for binary controls, used for providing runtime configuration of algorithm coefficients. - A new DAPM widget type for regulator supplies allowing drivers for devices that can power down unused supplies while active to do without any per-driver code. - DAPM widgets for DAIs, initially giving a speed boost for playback startup and shutdown and also the basis for CODEC<->CODEC DAI link support. - Support for specifying the number of significant bits on audio interfaces, useful for allowing applications to know how much effort to put into generating data for a larger sample format. - Conversion of the FSI driver used on some SH processors to DMAEngine. - Conversion of EP93xx drivers to DMAEngine. - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics WM2200. - Move audmux driver from arc/arm to sound/soc - McBSP move from arch/ to sound/ and updates Also, a few small updates and fixes for other drivers like au88x0, ymfpci, USB 6fire, USB usx2yaudio are included." * tag 'sound-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (446 commits) ASoC: wm8994: Provide VMID mode control and fix default sequence ASoC: wm8994: Add missing break in resume ASoC: wm_hubs: Don't actively manage LINEOUT_VMID_BUF ASoC: pxa-ssp: atomically set stream active masks ASoC: fsl: p1022ds: tell the WM8776 codec driver that it's the master ASoC: Samsung: Added to support mono recording ALSA: hda - Fix build with CONFIG_PM=n ALSA: au88x0 - Avoid possible Oops at unbinding ALSA: usb-audio - Fix build error by consitification of rate list ASoC: core: Fix obscure leak of runtime array ALSA: pcm - Avoid GFP_ATOMIC in snd_pcm_link() ALSA: pcm: Constify the list in snd_pcm_hw_constraint_list ASoC: wm8996: Add 44.1kHz support ALSA: hda - Fix build of patch_sigmatel.c without CONFIG_SND_HDA_POWER_SAVE ASoC: mx27vis-aic32x4: Convert it to platform driver ALSA: hda - fix printing of high HDMI sample rates ALSA: ymfpci - Fix legacy registers on S3/S4 resume ALSA: control - Fixe a trailing white space error ALSA: hda - Add expose_enum_ctl flag to snd_hda_add_vmaster_hook() ALSA: hda - Add "Mute-LED Mode" enum control ...

2011-09-28ALSA: hda - Add snoop optionTakashi Iwai1-0/+1
Added a new option "snoop" for the traffic control of the HD-audio controller chip. When set to 0, the non-snooping mode is used with the traffic control bit is set in each stream control register. This may allow better operations in the low power mode, but the actual implementation is depending pretty much on the chipset. As already implemented, more or less each chipset has own snoop-control register bit. Now this setup refers to the snoop option, too. Also, a new VIA chipset may require the non-snooping mode when set so in BIOS. In such a case, the option value is overridden. As default, it's still set to snoop=1 for keeping the same behavior as before. In near future, it'll be set to 0 as default after checking it works in every system well.

2011-08-04ALSA: hda: option to enable arbitrary buffer/period sizesPierre-Louis Bossart1-0/+5
Add new parameter to disable rounding of buffer/period sizes to multiples of 128 bytes. This is more efficient in terms of memory access but isn't required by the HDA spec and prevents users from specifying exact period/buffer sizes. For example for 44.1kHz, a period size set to 20ms will be rounded to 19.59ms. Tested and enabled on Intel HDA controllers. Option is disabled by default for other controllers.

Added a new driver for supporting Digigram Lola PCI-e boards. Lola has a similar h/w design like HD-audio but with extended verbs. Thus the driver is written similarly like HD-audio driver in the bus part. The codec part is rather written in a fixed way specific to the Lola board because of the verb incompatibility.

2010-08-13ALSA: ISA: New Aztech Sound Galaxy driverRené Herman1-0/+68
This is a new driver for Aztech Sound Galaxy ISA soundcards based on the AZT1605 and AZT2316 chipsets. It's constructed as two seperate drivers for either chipset generated from the same source file, with (very) minimal ifdeffery. The drivers check the SB DSP version to decide if they are being loaded for the right chip. AZT1605 returns 2.1 by default and AZT2316 3.1. This isn't full-proof as the DSP version can actually be set through software but it's close enough -- as far as I've been able to see, the DSP version can not be stored in the EEPROM and the cards will therefore startup with the defaults. This distinction could (with the same success rate) also be used to decide which chip we're looking at at runtime meaning a single, merged driver is also an option but I feel it's actually nicer this way. A merged driver would have to postpone translating the passed in resource values to the card configuration until it knew which one it was looking at and would need to postpone erring out on mpu_irq=10 for azt1605 and mpu_irq=3 for azt2316. The drivers have been tested on various cards. For snd-azt1605: FCC-ID I38-MMSN811: Aztech Sound Galaxy Nova 16 Extra FCC-ID I38-MMSN822: Aztech Sound Galaxy Pro 16 II and for snd-azt2316: FCC-ID I38-MMSN824: Aztech Sound Galaxy Pro 16 AB FCC-ID I38-MMSN826: Trust Sound Expert DeLuxe Wave 32 (05201) FCC-ID I38-MMSN830: Trust Sound Expert DeLuxe 16+ (05202) FCC-ID I38-MMSN837: Packard Bell ISA Soundcard 030069 FCC-ID I38-MMSN846: Trust Sound Expert DeLuxe 16-3D (06300) FCC-ID I38-MMSN847: Trust Sound Expert DeLuxe Wave 32-3D (06301) FCC-ID I38-MMSN852: Aztech Sound Galaxy Waverider Pro 32-3D 826 and 846 were also marketed directly by Aztech and then known as: FCC-ID I38-MMSN826: Aztech Sound Galaxy Waverider 32+ FCC-ID I38-MMSN846: Aztech Sound Galaxy Nova 16 Extra II-3D Together, these cover the AZT1605 and AT2316A, AZT2316R and AZT2316-S chipsets. All cards work fully -- full-duplex PCM, MIDI and FM. Full duplex is a little flaky on some. I38-MSN811 tends to not work in full-duplex but sometimes does with the highest success rate being achieved when you first start the capture and then a playback instead of the other way around (it's a CS4231-KL codec). The cards with an AD1845XP codec (my I38-MMSN826 and one of my I38-MMSN830s) are also somewhat duplex-challenged. Sometimes full-duplex works, sometimes not and this varies from try to try. This seems likely to be a timing problem somewhere inside wss-lib. I38-MMSN826 has an additional "ICS2115 WaveFront" wavetable synth onboard that isn't supported yet. The wavetable synths on I38-MMSN847 and I38-MMSN852 are wired directly to the standard MPU-401 UART and the AUX1 input on the codec and work without problem. CD-ROM audio on the cards is routed to the codec "Line" input, Line-In to its Aux input, and FM/Wavetable to its AUX1 input. I did not rename the controls due to the capture source enumeration: I see that capture-source overrides are hardcoded in wss-lib and this is just too ugly to live. Versus the old snd-sgalaxy driver these drivers add support for the models without a configuration EEPROM (which are common), full-duplex, MPU-401 UART and OPL3. In the future they might grow support for that ICS2115 WaveFront synth on 826 and an hwdep interface to write to the EEPROM on the models that have one.

The ESS ES968 chip is nothing more then a PnP companion for a non-PnP audio chip. It was paired with non-PnP ESS' chips: ES688 and ES1688. The ESS' audio chips are handled by the es1688 driver in native mode. The PnP cards are handled by the ES968 driver in SB compatible mode. Move the ES968 chip handling to the es1688 driver so the driver can handle both PnP and non-PnP cards. The es968 is removed.
