| | | | | | | | | | | | | | | | | | | | | | We used a on-demand i915 component binding for IvyBridge and SandyBridge HDMI codecs, but it has a potential problem of the nested module loading. For avoiding that situation, assure the i915 binding happening at the controller driver level for PCH controller devices, where the initialization is performed in a detached work, instead of calling from the codec driver probe.

* | ALSA: hda - add DP MST audio supportLibin Yang2017-01-121-52/+193
|/ | | | | | | | | | | | | | | | | | | | | | This patch adds the DP MST audio support on i915 platform and it will enable dyn_pcm_assign feature. DP MST supports several device entry on the same port and each device entry can map to one pcm stream. For example, on i915, there are 3 pins, and each pin has 3 device entries. This means there should be 3x3 pcms. However, there is only 3 pipe lines in i915. This means 3 pcms are actived at most at the same moment. We will create 5 pcms (pin number + dev entry num - 1) in this case. For the details, please refer commit a76056f2e57e ("ALSA: hda - hdmi dynamically bind PCM to pin when monitor hotplug") Each device entry is a virtual pin. It is described by pin_nid and dev_id in struct hdmi_spec_per_pin.

* drm/i915/dp: DP audio API changes for MSTPandiyan, Dhinakaran2016-09-221-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DP MST provides the capability to send multiple video and audio streams through a single port. This requires the API's between i915 and audio drivers to distinguish between multiple audio capable displays that can be connected to a port. Currently only the port identity is shared in the APIs. This patch adds support for MST with an additional parameter 'int pipe'. The existing parameter 'port' does not change it's meaning. pipe = MST : display pipe that the stream originates from Non-MST : -1 Affected APIs: struct i915_audio_component_ops - int (*sync_audio_rate)(struct device *, int port, int rate); + int (*sync_audio_rate)(struct device *, int port, int pipe, + int rate); - int (*get_eld)(struct device *, int port, bool *enabled, - unsigned char *buf, int max_bytes); + int (*get_eld)(struct device *, int port, int pipe, + bool *enabled, unsigned char *buf, int max_bytes); struct i915_audio_component_audio_ops - void (*pin_eld_notify)(void *audio_ptr, int port); + void (*pin_eld_notify)(void *audio_ptr, int port, int pipe); This patch makes dummy changes in the audio drivers (thanks Libin) for build to succeed. The audio side drivers will send the right 'pipe' values for MST in patches that will follow. v2: Renamed the new API parameter from 'dev_id' to 'pipe'. (Jim, Ville) Included Asoc driver API compatibility changes from Jeeja. Added WARN_ON() for invalid pipe in get_saved_encoder(). (Takashi) Added comment for av_enc_map[] definition.

This is of little use to the userspace application. With this patch, it parses the spk_alloc block as queried from the ELD, and copies only the corresponding mapping channel allocation entries from the cea channel speaker allocation table. Thus the user can parse the TLV container to identify sink's capability and set the channel map accordingly. It shouldn't impact the behavior in AMD chipset, as this makes use of already parsed spk alloc block to calculate the channel map. Signed-off-by: Subhransu S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intel IronLake and ValleyView platforms have different HDMI widget pin and digital port mapping from other newer ones. The recent ones (HSW+) have NID 0x05 to 0x07 for port B to port D, while these chips have NID 0x04 to 0x06. For adapting this mapping, pass the codec object instead of the bus object to snd_hdac_sync_audio_rate() and snd_hdac_acomp_get_eld() so that they can check the codec ID and calculate the mapping properly. The changes in the HDMI codec driver side will follow in the later patch. Signed-off-by: Takashi Iwai <tiwai@suse.de>

For HSW+ and VLV+ codecs, set this ops so that the driver can call the Intel-specific workarounds appropriately.

And this makes it difficult to adjust per chipset, e.g. for allowing the audio notifier on an old chipset, one would need to add an explicit if() check. This patch attempts some code refactoring and cleanups in this regard; the Intel-specific codes are moved out of patch_generic_hdmi() into the new functions, patch_i915_hsw_hdmi() and patch_i915_byt_hdmi(), depending on the chipset. The other old Intel chipsets keep using patch_generic_hdmi() without Intel hacks. The existing patch_generic_hdmi() is also split to a few components so that they can be called from the Intel codec parsers. There are still many is_haswell*() and is_valleyview*() macro usages in the code. They will be cleaned up later. For the time being, only the entry are concerned. Along with this change, the i915_bound flag and the on-demand i915 component binding have been removed as a cleanup, since there is no user at this moment. This will be added back later once when Cougar Point and else start using the i915 eld notifier. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* | | ALSA: hda - Fix regression on ATI HDMI audioTakashi Iwai2016-05-111-4/+3
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The HDMI/DP audio output on ATI/AMD chips got broken due to the recent restructuring of chmap. Fortunately, Daniel Exner could bisect, and pointed the culprit commit [739ffee97ed5: ALSA: hda - Add hdmi chmap verb programming ops to chmap object]. This commit moved some ops from hdmi_ops to chmap_ops, and reassigned the ops in the embedded chmap object in hdmi_spec instead. Unfortunately, the reassignment of these ops in patch_atihdmi() were moved into an if block that is performed only for old chips. Thus, on newer chips, the generic ops is still used, which doesn't work for such ATI/AMD chips. This patch addresses the regression, simply by moving the assignment of chmap ops to the right place.

* | ALSA: hda - Update BCLK also at hotplug for i915 HSW/BDWTakashi Iwai2016-04-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent bug report suggests that BCLK setup for i915 HSW/BDW needs to be updated at each HDMI hotplug, not only at initialization and resume. That is, we need to update HSW_EM4 and HSW_EM5 registers at ELD notification, too. Otherwise the HDMI audio may be out of sync and played in a wrong pitch. However, the HDA codec driver has no access to the controller registers, and currently the code managing these registers is in hda_intel.c, i.e. local to the controller driver. For allowing the explicit BCLK update from the codec driver, as in this patch, the former haswell_set_bclk() in hda_intel.c is moved to hdac_i915.c and exposed as snd_hdac_i915_set_bclk(). This is called from both the HDA controller driver and intel_pin_eld_notify() in HDMI codec driver. Along with this change, snd_hdac_get_display_clk() gets dropped as it's no longer used.

The fix is to update pin_eld->monitor_present as well before calling update_eld(). Note that this may still leave monitor_present flag in an inconsistent state when the driver repolls, but this is at least the old behavior. More proper fix will follow in the later patch.

* ALSA: hda - Workaround for unbalanced i915 power refcount by concurrent probeTakashi Iwai2016-03-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent addition of on-demand i915 audio component binding in the codec driver seems leading to the unbalanced i915 power refcount, according to Intel CI tests. Typically, it gets a kernel WARNING like: WARNING: CPU: 3 PID: 173 at sound/hda/hdac_i915.c:91 snd_hdac_display_power+0xf1/0x110 [snd_hda_core]() Call Trace: [<ffffffff813fef15>] dump_stack+0x67/0x92 [<ffffffff81078a21>] warn_slowpath_common+0x81/0xc0 [<ffffffff81078b15>] warn_slowpath_null+0x15/0x20 [<ffffffffa00f77e1>] snd_hdac_display_power+0xf1/0x110 [snd_hda_core] [<ffffffffa015039d>] azx_intel_link_power+0xd/0x10 [snd_hda_intel] [<ffffffffa011e32a>] azx_link_power+0x1a/0x30 [snd_hda_codec] [<ffffffffa00f21f9>] snd_hdac_link_power+0x29/0x40 [snd_hda_core] [<ffffffffa01192a6>] hda_codec_runtime_suspend+0x76/0xa0 [snd_hda_codec] ..... The scenario is like below: - HD-audio driver and i915 driver are probed concurrently at the (almost) same time; HDA bus tries to bind with i915, but it fails because i915 initialization is still being processed. - Later on, HD-audio probes the HDMI codec, where it again tries to bind with i915. At this time, it succeeds. - At finishing the probe of HDA, it decreases the refcount as if it were already bound at the bus probe, since the component is bound now. This triggers a kernel WARNING due to the unbalance. As a workaround, in this patch, we just disable the on-demand i915 component binding in the codec driver. This essentially reverts back to the state of 4.4 kernel. We know that this is no real solution, but it's a minimalistic simple change that can be applied to 4.5.x kernel as stable.

The fix is to limit the call of this function again only for the chips with the proper binding. This can be identified by the same flag as the eld notifier.

| | | | | | | | | | | | | | | | | | The commit [b62232d429fa: ALSA: hda - Limit i915 HDMI binding only for HSW and later] tried to limit the usage of i915 audio notifier to the recent Intel models and switch to the old method on pre-Haswell models. However, it assumed that the i915 component binding hasn't been done on such models, and the assumption was wrong: namely, Baytrail had already the i915 component binding due to powerwell control. Thus, the workaround wasn't applied to Baytrail. For fixing this properly, this patch introduces a new flag indicating the usage of audio notifier and codec_has_acomp() refers to this flag instead of checking the existence of audio component.

* ALSA: hda - Fix mutex deadlock at HDMI/DP hotplugTakashi Iwai2016-03-171-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent change in HD-audio HDMI/DP codec driver for allowing the dynamic PCM binding introduced a new spec->pcm_mutex. One of the protected area by this mutex is hdmi_present_sense(). As reported by Intel CI tests, unfortunately, the new mutex causes a deadlock when the hotplug/unplug is triggered during the codec is in runtime suspend. The buggy code path is like the following: hdmi_unsol_event() -> ... -> hdmi_present_sense() ==> ** here taking pcm_mutex -> hdmi_present_sense_via_verbs() -> snd_hda_power_up_pm() -> ... (runtime resume calls) -> generic_hdmi_resume() -> hdmi_present_sense() ==> ** here taking pcm_mutex again! As we can see here, the problem is that the mutex is taken before snd_hda_power_up_pm() call that triggers the runtime resume. That is, the obvious solution is to move the power up/down call outside the mutex; it is exactly what this patch provides. The patch also clarifies why this bug wasn't caught beforehand. We used to have the i915 audio component for hotplug for all Intel chips, and in that code path, there is no power up required but the information is taken directly from the graphics side. However, we recently switched back to the old method for some old Intel chips due to regressions, and now the deadlock issue is surfaced.

* ALSA: hda - Limit i915 HDMI binding only for HSW and laterTakashi Iwai2016-03-151-2/+3
| | | | | | | | | | | | | | It turned out that the pre-HSW Intel chips are incompatible with the naive assumption we had -- the fixed mapping between the port and the HD-audio widget. This may result in the bad access, as captured by the recent patch to add a WARN_ON() for the port mapping check. As a quick workaround, disable the i915 audio component binding for all pre-Haswell models.

| * ALSA: hda - Don't handle ELD notify from invalid portTakashi Iwai2016-03-101-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current Intel HDMI codec driver supports only three fixed ports from port B to port D. However, i915 driver may assign a DP on other ports, e.g. port A, when no eDP is used. This incompatibility is caught later at pin_nid_to_pin_index() and results in a warning message like "HDMI: pin nid 4 not registered" at each time. This patch filters out such invalid events beforehand, so that the kernel won't be too grumbling.
