2015-12-09ALSA: hda - Less grumbling about lack of i915 bindingTakashi Iwai
The recent commit [6603249dcdbb: ALSA: hda - Enable audio component for old Intel PCH devices] enabled the i915 binding for HDMI/DP on old Intel PCHs. But many boards are without HDMI/DP, and they actually don't need i915 binding, and yet the driver has a check of i915 binding and complains like Haswell must be built with CONFIG_SND_HDA_I915 This error is false-positive, and it should be put only for HSW/BDW, instead of all devices that may be bound with i915. This patch fixes the condition to check, as well as rephrasing the message specific to HSW/BDW HDMI/DP.

2015-12-04ALSA: hda - Enable audio component for old Intel PCH devicesTakashi Iwai
As i915 graphics driver provides the notification via audio component, not only the currently implemented HSW+ and VLV+ platforms but also all other PCH-based platforms (e.g. Cougar Point, Panther Point, etc) can use this infrastructure. It'll improve the reliability and the power consumption significantly, especially once when we implement the ELD notification via component. As a preliminary, this patch enables the usage of audio component for all PCH platforms. The HDA controller just needs to set AZX_DCAPS_I915_POWERWELL flag appropriately. The name of the flag is a bit confusing, but this actually works even on the chips without the powerwell but accesses only the other component ops. In the HDMI/DP codec driver side, we just need to register/unregister the notifier for such chips. This can be identified by checking the audio_component field in the assigned hdac_bus. One caveat is that PCH for Haswell and Broadwell must not be bound with i915 audio component, as there are dedicated HD-audio HDMI controllers on these platforms. Ditto for Poulsbo and Oaktrail as they use gma500 graphics, not i915. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-10-27ALSA: hda - Disable 64bit address for Creative HDA controllersTakashi Iwai
We've had many reports that some Creative sound cards with CA0132 don't work well. Some reported that it starts working after reloading the module, while some reported it starts working when a 32bit kernel is used. All these facts seem implying that the chip fails to communicate when the buffer is located in 64bit address. This patch addresses these issues by just adding AZX_DCAPS_NO_64BIT flag to the corresponding PCI entries. I casually had a chance to test an SB Recon3D board, and indeed this seems helping. Although this hasn't been tested on all Creative devices, it's safer to assume that this restriction applies to the rest of them, too. So the flag is applied to all Creative entries.

2015-09-24vga_switcheroo: Set active attribute to false for audio clientsLukas Wunner
The active attribute in struct vga_switcheroo_client denotes whether the outputs are currently switched to this client. The attribute is only meaningful for vga clients. It is never used for audio clients. The function vga_switcheroo_register_audio_client() misuses this attribute to store whether the audio device is fully initialized. Most likely there was a misunderstanding about the meaning of "active" when this was added. Comment from Takashi's review: "Not really. The full initialization of audio was meant that the audio is active indeed. Admittedly, though, the active flag for each audio client doesn't play any role because the audio always follows the gfx state changes, and the value passed there doesn't reflect the actual state due to the later change. So, I agree with the removal of the flag itself -- or let the audio active flag following the corresponding gfx flag. The latter will make the proc output more consistent while the former is certainly more reduction of code." Set the active attribute to false for audio clients. Remove the active parameter from vga_switcheroo_register_audio_client() and its sole caller, hda_intel.c:register_vga_switcheroo(). vga_switcheroo_register_audio_client() was introduced by 3e9e63dbd374 ("vga_switcheroo: Add the support for audio clients"). Its use in hda_intel.c was introduced by a82d51ed24bb ("ALSA: hda - Support VGA-switcheroo"). v1.1: The changes above imply that in find_active_client() the call to client_is_vga() is now superfluous. Drop it.

2015-07-20ALSA: hda - Fix Skylake codec timeoutDavid Henningsson
When the controller is powered up but the HDMI codec is powered down on Skylake, the power well is turned off. When the codec is then powered up again, we need to poke the codec a little extra to make sure it wakes up. Otherwise we'll get sad "no response from codec" messages and broken audio. This also changes azx_runtime_resume to actually call snd_hdac_set_codec_wakeup for Skylake (before STATETS read). (Otherwise it would only have been called for Haswell and Broadwell, which both do not need it, so this probably was not the author's intention.)

2015-06-12ALSA: hda - Abort the probe without i915 binding for HSW/BDWTakashi Iwai
The previous patch tried to continue the probe if i915 binding fails. For for simplicity reason, we haven't implemented abort even for controller chips that are dedicated for HDMI/DP on HSW and BDW. However, Mengdong suggested that this can be dangerous; BIOS may disable gfx power well although the PCI entry for HD-audio is left, and this may result in the unexpected behavior, kernel errors, etc. For avoiding this situation, abort the probe at i915 binding failure only for HSW/BDW chips selectively. For other chips, it still continues.

2015-06-11ALSA: hda - Continue probing even if i915 binding failsTakashi Iwai
Currently snd-hda-intel driver aborts the probing of Intel HD-audio controller with i915 power well management when binding with i915 driver via hda_i915_init() fails. This is no big problem for Haswell and Broadwell where the HD-audio controllers are dedicated to HDMI/DP, thus i915 link is mandatory. However, Skylake, Baytrail and Braswell have only one controller and both HDMI/DP and analog codecs share the same bus. Thus, even if HDMI/DP isn't usable, we should keep the controller working for other codecs. For fixing this, this patch simply allows continuing the probing even if hda_i915_init() call fails. This may leave stale sound components for HDMI/DP devices that are unbound with graphics. We could abort the probing selectively, but from the code simplicity POV, it's better to continue in all cases.

2015-04-29ALSA: hda - divide controller and codec dependency on i915 gfx power wellMengdong Lin
This patch can improve power saving for Intel platforms on which only the display audio codec is in the shared i915 power well: - Add a flag "need_i915_power" to indicate whether the controller needs the i915 power well. - The driver will always request the i915 power when probing the controller and codecs if AZX_DCAPS_I915_POWERWELL is set (either the controller or a codec needs this power). - If the controller needs the i915 power, the power will be held after probe until the controller is runtime suspended or S3. If the controller doesn't need the power, the power will be released the after probe, and a codec that needs the power can request/release the power via bus link_power ops. Background: - For Haswell/Broadwell, which has a separate HD-A controller for display audio, both the controller and the display codec are in the i915 power well. - For Baytrail/Braswell, the display and analog audio share the same HDA controller and link, and only the display codec is in the i915 power well. - For Skylake, the display and analog audio share the same HDA controller but use separate links. Only the display codec is in the i915 power well. And in legacy mode we take the two links as one. So it can follow Baytrail/Braswell.

2015-04-21ALSA: hda - add AZX_DCAPS_I915_POWERWELL to BaytrailMengdong Lin
This patch addes AZX_DCAPS_I915_POWERWELL to BYT (Baytrail). Like Braswell and Skylake, the HDMI codec on Bytrail is also in the shared power well with GPU. This power well must be turned on before we reset link to probe the codec, to avoid communication failure with the codec. The side effect is that this power is always ON in S0 because the BYT HDMI codec does not support EPSS or D3ClkStop and so the controller doesn't enter D3 at runtime, and the HDMI codec and analog codec share a single physical HD-A link and so we cannot reset the HD-A link freely when we re-enable the power to use the HDMI codec. Next step is to test if an AGP reset or double AGP reset on BYT HDMI codec is okay to bring the HDMI codec back to a functional state after restoring the power. If okay, we can bind the power on/off with the HDMI codec PM without interrupting the analog audio. Signed-off-by: Mengdong Lin <mengdong.lin@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

They are no longer used (only one place which can be replaced with a proper helper function). Let's drop. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-04-16ALSA: hda - Minor refactoringTakashi Iwai
Move the small portion of the common sequence in hda_intel.c and hda_tegra.c into hda_controller.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-04-16ALSA: hda - Embed bus into controller objectTakashi Iwai
... and replace with the existing hda-core helper codes. This reduces lots of lines, finally. Since struct hda_bus is now embedded into struct azx, snd_hda_bus_new() is moved and expanded from hda_codec.c to hda_controller.c, accordingly. Also private_free bus ops and private_data field are removed because we no longer need to point azx object from bus (we can use container_of()) The spin locks are consolidated into the single one, bus->reg_lock.

2015-04-16ALSA: hda - Migrate more hdac_stream codesTakashi Iwai
... including dsp loader helpers. Lots of codes removed. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-04-16ALSA: hda - Migrate hdac_stream into legacy driverTakashi Iwai
Embed hdac_stream object into azx_dev, and use a few basic helper functions. The most of helper codes for hdac_stream aren't still used yet. Also this commit disables the tracepoints temporarily due to build problems. It'll be enabled again later. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-04-16ALSA: hda - Pass bus io_ops directly from the top-level driverTakashi Iwai
One less redirection again. This also requires the change of the call order in the toplevel divers. Namely, the bus has to be created at first before other initializations since the memory allocation ops are called through bus object now. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-04-07ALSA: hda_intel: add AZX_DCAPS_I915_POWERWELL for SKL and BSWLibin Yang
HDMI/DP codec on SKL/BSW is in the power well. The power well must be turned on before probing the HDMI/DP codec. This is a temporary patch, which will power on the powerwell by adding AZX_DCAPS_I915_POWERWELL for SKL and BSW. After restructuring and new flag is added, this patch will be reverted.

2015-03-26ALSA: hda_intel: apply the Seperate stream_tag for Sunrise PointLibin Yang
The total stream number of Sunrise Point's input and output stream exceeds 15, which will cause some streams do not work because of the overflow on SDxCTL.STRM field if using the legacy stream tag allocation method. This patch uses the new stream tag allocation method by add the flag AZX_DCAPS_SEPARATE_STREAM_TAG for Skylake platform.

2015-03-23ALSA: hda - Move some codes up to hdac_bus structTakashi Iwai
A few basic codes for communicating over HD-audio bus are moved to struct hdac_bus now. It has only command and get_response ops in addition to the unsolicited event handling. Note that the codec-side tracing support is disabled temporarily during this transition due to the code shuffling. It will be re-enabled later once when all pieces are settled down.
