2018-07-17ALSA: hda: Make audio component support more genericTakashi Iwai1-13/+37
This is the final step for more generic support of DRM audio component. The generic audio component code is now moved to its own file, and the symbols are renamed from snd_hac_i915_* to snd_hdac_acomp_*, respectively. The generic code is enabled via the new kconfig, CONFIG_SND_HDA_COMPONENT, while CONFIG_SND_HDA_I915 is kept as the super-class. Along with the split, three new callbacks are added to audio_ops: pin2port is for providing the conversion between the pin number and the widget id, and master_bind/master_unbin are called at binding / unbinding the master component, respectively. All these are optional, but used in i915 implementation and also other later implementations. A note about the new snd_hdac_acomp_init() function: there is a slight difference between this and the old snd_hdac_i915_init(). The latter (still) synchronizes with the master component binding, i.e. it assures that the relevant DRM component gets bound when it returns, or gives a negative error. Meanwhile the new function doesn't synchronize but just leaves as is. It's the responsibility by the caller's side to synchronize, or the caller may accept the asynchronous binding on the fly. v1->v2: Fix missing NULL check in master_bind/unbind Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-07-17ALSA: hda/i915: Associate audio component with devresTakashi Iwai1-2/+3
The HD-audio i915 binding code contains a single pointer, hdac_acomp, for allowing the access to audio component from the master bind/unbind callbacks. This was needed because the callbacks pass only the device pointer and we can't guarantee the object type assigned to the drvdata (which is free for each controller driver implementation). And this implementation will be a problem if we support multiple components for different DRM drivers, not only i915. As a solution, allocate the audio component object via devres and associate it with the given device, so that the component callbacks can refer to it via devres_find(). The removal of the object is still done half-manually via devres_destroy() to make the code consistent (although it may work without the explicit call). Also, the snd_hda_i915_register_notifier() had the reference to hdac_acomp as well. In this patch, the corresponding code is removed by passing hdac_bus object to the function, too.

2018-07-17drm/i915: Split audio component to a generic typeTakashi Iwai1-4/+4
For allowing other drivers to use the DRM audio component, rename the i915_audio_component_* with drm_audio_component_*, and split the generic part into drm_audio_component.h. The i915 specific stuff remains in struct i915_audio_component, which contains drm_audio_component as the base. The license of drm_audio_component.h is kept to MIT as same as the the original i915_component.h. This is a preliminary change for further development, and no functional changes by this patch itself, merely code-split and renames. v1->v2: Use SPDX for drm_audio_component.h, fix remaining i915 argument in drm_audio_component.h Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2018-07-02ALSA: hda - Handle pm failure during hotplugChris Wilson1-5/+14
Obtaining the runtime pm wakeref can fail, especially in a hotplug scenario where i915.ko has been unloaded. If we do not catch the failure, we end up with an unbalanced pm. v2 additions by tiwai: hdmi_present_sense() checks the return value and handle only a negative error case and bails out only if it's really still suspended. Also, snd_hda_power_down() is called at the error path so that the refcount is balanced. Along with it, the spec->pcm_lock is taken outside hdmi_present_sense() in the caller side, so that it won't cause deadlock at reentrace via runtime resume. v3 fix by tiwai: Missing linux/pm_runtime.h is included.

Split snd_hda_codec_new into two separate functions. snd_hda_codec_device_init allocates memory and registers with bus. snd_hda_codec_device_new initialializes the fields and performs snd_device_new. This enables reuse of legacy HDA codec drivers as ASoC codec drivers.

2018-06-21ALSA: hda - Force to link down at runtime suspend on ATI/AMD HDMITakashi Iwai3-2/+9
Henning Kühn reported that the discrete AMD GPU on his hybrid graphics laptop no longer runtime-suspends due to the recent commit 07f4f97d7b4b ("vga_switcheroo: Use device link for HDA controller"). The root cause is that the HDMI codec on AMD GPU doesn't support CLKSTOP and EPSS, which are currently mandatory for powering down the HD-audio link at runtime suspend. Because the HD-audio link is still up, HD-audio controller driver blocks the transition to D3. For addressing the regression, this patch adds a new flag to indicate the forced link-down, and sets it for AMD HDMI codecs appropriately in the codec driver.

2018-06-17ALSA: hda/ca0132: Fix DMic data rate for Alienware M17x R4Alastair Bridgewater1-1/+6
The commentary says to use various parameters, and lays out what the mapping is... The code used a 32KHz rate when the comment says that it needs to use a 48KHz rate. And this has been the case since day one. On the Alienware M17x R4, the DMic used to have exceptionally quiet pickup and a lot of noise. Changing the data rate fixes both of these issues. Searching the kernel bug tracker for ca0132-related issues shows no mention of this being an issue for other hardware, and I have no other hardware to test with, so a quirk is used to limit the effect to just the M17x R4.

QUIRK_NONE is, quite explicitly, the default case. The entire point of a quirks system is to allow "programming by difference" from a given base case, which requires that merely defining a new quirk for some piece of hardware should not change the behavior of the driver for that hardware. In turn, this means that testing for QUIRK_NONE explicitly is a violation of that implicit contract. Change a test for QUIRK_NONE and QUIRK_ALIENWARE to default, and add a test for QUIRK_SBZ to disable the default behavior in that instance.

2018-06-13ALSA: hda/realtek - Add shutup hintTakashi Iwai1-0/+3
The pin shutup callback seems working well on some devices while it does harm on some other devices; e.g. Lenovo laptops show often the noises at (runtime) PM with the pin shutup enabled. Currently, the only way to disable the pin shutup is to hard-code spec->shutup = alc_no_shutup; in the fixup, and this makes the debugging harder for normal users. For allowing users to test the similar effect without recompiling the kernel, this patch adds a new hint string "shutup". It's a boolean value, and by passing false to this, user can turn off the pin shutup call. For example, to turn off the shutup on Lenovo P50, create a "firmware patch" file (e.g. /lib/firmware/alsa/lenovo-p50) containing the following lines: [codec] 0x10ec0298 0x17aa222e 0 [hint] shutup = no and pass the file via patch option of snd-hda-intel module (e.g. patch=alsa/lenovo-p50).

2018-06-01ALSA: hda - Handle kzalloc() failure in snd_hda_attach_pcm_stream()Bo Chen1-1/+3
When 'kzalloc()' fails in 'snd_hda_attach_pcm_stream()', a new pcm instance is created without setting its operators via 'snd_pcm_set_ops()'. Following operations on the new pcm instance can trigger kernel null pointer dereferences and cause kernel oops. This bug was found with my work on building a gray-box fault-injection tool for linux-kernel-module binaries. A kernel null pointer dereference was confirmed from line 'substream->ops->open()' in function 'snd_pcm_open_substream()' in file 'sound/core/pcm_native.c'. This patch fixes the bug by calling 'snd_device_free()' in the error handling path of 'kzalloc()', which removes the new pcm instance from the snd card before returns with an error code.

2018-05-24ALSA: hda - Fix runtime PMLukas Wunner1-2/+4
Before commit 3b5b899ca67d ("ALSA: hda: Make use of core codec functions to sync power state"), hda_set_power_state() returned the response to the Get Power State verb, a 32-bit unsigned integer whose expected value is 0x233 after transitioning a codec to D3, and 0x0 after transitioning it to D0. The response value is significant because hda_codec_runtime_suspend() does not clear the codec's bit in the codec_powered bitmask unless the AC_PWRST_CLK_STOP_OK bit (0x200) is set in the response value. That in turn prevents the HDA controller from runtime suspending because azx_runtime_idle() checks that the codec_powered bitmask is zero. Since commit 3b5b899ca67d, hda_set_power_state() only returns 0x0 or 0x1, thereby breaking runtime PM for any HDA controller. That's because an inline function introduced by the commit returns a bool instead of a 32-bit unsigned int. The change was likely erroneous and resulted from copying and pasting snd_hda_check_power_state(), which is immediately preceding the newly introduced inline function. Fix it.
