2009-12-11intelhdmi - dont power off HDA linkWu Fengguang
For codecs without EPSS support (G45/IbexPeak), the hotplug event will be lost if the HDA is powered off during the time. After that the pin presence detection verb returns inaccurate info. So always power-on HDA link for !EPSS codecs. KarL offers the fact and Takashi recommends to flag hda_bus. Thanks!

2009-12-11ALSA: intelhdmi - add channel mapping for typical configurationsWu Fengguang
IbexPeak is the first Intel HDMI audio codec to support channel mapping. Currently the outstanding problem is, the HDMI channel order do not agree with that of ALSA. This patch presents workaround for some typical use cases. It gives priority to the typical ALSA surround configurations, and defines channel mapping for them. We may need better kernel+userspace interactive channel mapping scheme. For example, in current scheme if user plays with the surround50 device, the kernel is unaware of this and will still select the surround41 channel allocation and channel mapping.. Thanks to Marcin for offering good tips! Signed-off-by: Wu Fengguang <fengguang.wu@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-12-11ALSA: intelhdmi - channel mapping applies to PinWu Fengguang
HDA036-A specifies that the Audio Sample Packet (ASP) Channel Mapping verbs apply to Digital Display Pin Complex instead of Converter. With this fix, channel mapping is working as expected for IbexPeak. Thanks to Marcin for pointing this out!

2009-12-11ALSA: intelhdmi - accept DisplayPort pinWu Fengguang
HDA036 spec states: DP (Display Port) indicates whether the Pin Complex Widget supports connection to a Display Port sink. Supported if set to 1. Note that it is possible for the pin widget to support more than one digital display connection type, e.g. HDMI and DP bit are both set to 1. Also export the DP pin cap in procfs.

2009-11-18ALSA: intelhdmi - sticky stream id and formatWu Fengguang
We tracked down the first-0.5s-hdmi-audio-samples-lost problem to the AC_VERB_SET_CHANNEL_STREAMID command. It is suspected that many HDMI sinks need some time to adapt to the new state. The workaround is to avoid changing stream id/format whenever possible. Proposed by David.

2009-10-30ALSA: hda - vectorize intelhdmiWu Fengguang
The Intel IbexPeak HDMI codec supports 2 converters and 3 pins, which requires converting the cvt_nid/pin_nid to arrays. The active pin number (the one connected with a live HDMI monitor/sink) will be dynamically identified on hotplug events. It exports two HDMI devices, so that user space can choose the A/V pipe for sending the audio samples. It's still undefined behavior when there are two active monitors connected and routed to the same audio converter.

2009-02-11ALSA: hda - enable HDMI audio pin out at module loading timeWu Fengguang
We found that enabling/disabling HDMI audio pin out at stream start/stop time will kill the leading 500ms or so sound samples. Avoid this by enabling pin out once and for ever at module loading time. The leading ~500ms audio samples will still be lost when switching from X-channel playback to Y-channel playback where X != Y. However there's no much we can do about it: the audio infoframe has to change and it looks like either G45 or YAMAHA requires some time to switch the configuration.

2009-02-11ALSA: hda - allow multi-channel HDMI audio playback when ELD is not presentWu Fengguang
The YAMAHA AV-X1800 requires audio infoframe to include speaker-channel mapping to play >2 channel HDMI audio. In theory that mapping should be derived from its speaker configurations contained in its ELD. However we currently cannot get ELD in console before the KMS functionalities are ready. This is a more or less general issue at least in the near future. As a workaround, we propose to allow playback of mult-channel audio when ELD is not available.

2008-11-27ALSA: hda - Modularize HD-audio driverTakashi Iwai
Split the monolithc HD-audio driver into several pieces: - snd-hda-intel HD-audio PCI controller driver; loaded via udev - snd-hda-codec HD-audio codec bus driver - snd-hda-codec-* Specific HD-audio codec drivers When built as modules, snd-hda-codec (that is invoked by snd-hda-intel) looks up the codec vendor ID and loads the corresponding codec module automatically via request_module(). When built in a kernel, each codec drivers are statically hooked up before probing the PCI. This patch adds appropriate EXPORT_SYMBOL_GPL()'s and the module information for each driver, and driver-linking codes between codec-bus and codec drivers.

2008-11-19ALSA: hda: HDMI channel allocations for audio infoframeWu Fengguang
To play a 3+ channels LPCM/DSD stream via HDMI, - HDMI sink must tell HDMI source about its speaker placements (via ELD, speaker-allocation field) - HDMI source must tell the HDMI sink about channel allocation (via audio infoframe, channel-allocation field) (related docs: HDMI 1.3a spec section 7.4, CEA-861-D section 7.5.3 and 6.6) This patch attempts to set the CA(channel-allocation) byte in the audio infoframe according to - the number of channels in the current stream - the speakers attached to the HDMI sink A channel_allocations[] line must meet the following two criteria to be considered as a valid candidate for CA: 1) its number of allocated channels = substream->runtime->channels 2) its speakers are a subset of the available ones on the sink side If there are multiple candidates, the first one is selected. This simple policy shall cheat the sink into playing music, but may direct data to the wrong speakers. Signed-off-by: Wu Fengguang <wfg@linux.intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2008-11-18ALSA: ELD proc interface for HDMI sinksWu Fengguang
Create /proc/asound/card<card_no>/eld#<codec_no> to reflect the audio configurations and capabilities of the attached HDMI sink. Some notes: - Shall we show an empty file if the ELD content is not valid? Well it's not that simple. There could be partially populated ELD, and there may be malformed ELD provided by buggy drivers/monitors. So expose ELD as it is. - The ELD retrieval routines rely on the Intel HDA interface, others are/could be universal and independent ones. - How do we name the proc file? If there are going to be two HDMI pins per codec, then the current naming scheme (eld#<codec no>) will fail. Luckily the user space dependencies should be minimal, so it would be trivial to do the rename if that happens. - The ELD proc file content is designed to be easy for scripts and human reading. Its lines all have the pattern: <item_name>\t[\t]*<item_value> where <item_name> is a keyword in c language, while <item_value> could be any contents, including white spaces. <item_value> could also be a null value.
