2019-04-10ALSA: hda: Fix racy display power accessTakashi Iwai3-2/+6
snd_hdac_display_power() doesn't handle the concurrent calls carefully enough, and it may lead to the doubly get_power or put_power calls, when a runtime PM and an async work get called in racy way. This patch addresses it by reusing the bus->lock mutex that has been used for protecting the link state change in ext bus code, so that it can protect against racy display state changes. The initialization of bus->lock was moved from snd_hdac_ext_bus_init() to snd_hdac_bus_init() as well accordingly.

2019-02-25ALSA: hda: Extend i915 component bind timeoutTakashi Iwai1-2/+2
I set 10 seconds for the timeout of the i915 audio component binding with a hope that recent machines are fast enough to handle all probe tasks in that period, but I was too optimistic. The binding may take longer than that, and this caused a problem on the machine with both audio and graphics driver modules loaded in parallel, as Paul Menzel experienced. This problem haven't hit so often just because the KMS driver is loaded in initrd on most machines. As a simple workaround, extend the timeout to 60 seconds.

2019-02-14snd/hda, drm/i915: Track the display_power_status using a cookieChris Wilson1-6/+12
drm/i915 is tracking all wakeref owners with a cookie in order to identify leaks. To that end, each rpm acquisition ops->get_power is assigned a cookie which should be passed to ops->put_power to signify its release (and removal from the list of wakeref owners). As snd/hda is already using a bool to track current status of display_power extending that to an unsigned long to hold the boolean cookie is a trivial extension, and will quell all doubt that snd/hda is the cause of the device runtime pm leaks. v2: Keep using the power abstraction for local wakeref tracking. v3: BUILD_BUG_ON impedance mismatch Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Takashi Iwai <tiwai@suse.de> Cc: Jani Nikula <jani.nikula@intel.com> Acked-by: Takashi Iwai <tiwai@suse.de> Reviewed-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190213152109.16997-1-chris@chris-wilson.co.uk

2018-12-11ALSA: hda: Refactor display power managementTakashi Iwai2-30/+22
The current HD-audio code manages the DRM audio power via too complex redirections, and this seems even still unbalanced in a corner case as Intel DRM CI has been intermittently reporting. This patch is a big surgery for addressing the complexity and the possible unbalance. Basically the patch changes the display PM in the following ways: - Both HD-audio controller and codec drivers call a single helper, snd_hdac_display_power(). (Formerly, the display power control from a codec was done indirectly via link_power bus ops.) - snd_hdac_display_power() receives the codec address index. For turning on/off from the controller, pass HDA_CODEC_IDX_CONTROLLER. - snd_hdac_display_power() doesn't manage refcounts any longer, but keeps the power status in bitmap. If any of controller or codecs is turned on, the function updates the DRM power state via get_power() or put_power(). Also this refactor allows us more cleanup: - The link_power bus ops is dropped, so there is no longer indirect management, as mentioned in the above. - hdac_device link_power_control flag is moved to hda_codec display_power_control flag, as it's only for HDA legacy.

2018-09-12sound: don't call skl_init_chip() to reset intel skl socYu Zhao1-3/+4
Internally, skl_init_chip() calls snd_hdac_bus_init_chip() which 1) sets bus->chip_init to prevent multiple entrances before device is stopped; 2) enables interrupt. We shouldn't use it for the purpose of resetting device only because 1) when we really want to initialize device, we won't be able to do so; 2) we are ready to handle interrupt yet, and kernel crashes when interrupt comes in. Rename azx_reset() to snd_hdac_bus_reset_link(), and use it to reset device properly.

2018-09-12sound: enable interrupt after dma buffer initializationYu Zhao1-2/+6
In snd_hdac_bus_init_chip(), we enable interrupt before snd_hdac_bus_init_cmd_io() initializing dma buffers. If irq has been acquired and irq handler uses the dma buffer, kernel may crash when interrupt comes in. Fix the problem by postponing enabling irq after dma buffer initialization. And warn once on null dma buffer pointer during the initialization. Reviewed-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Yu Zhao <yuzhao@google.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-09-07regmap: split up regmap_config.use_single_rwDavid Frey1-1/+2
Split regmap_config.use_single_rw into use_single_read and use_single_write. This change enables drivers of devices which only support bulk operations in one direction to use the regmap_bulk_*() functions for both directions and have their bulk operation split into single operations only when necessary. Update all struct regmap_config instances where use_single_rw==true to instead set both use_single_read and use_single_write. No attempt was made to evaluate whether it is possible to set only one of use_single_read or use_single_write.

2018-07-24ALSA: hda/i915: Allow delayed i915 audio component bindingTakashi Iwai1-2/+22
Currently HD-audio i915 audio binding doesn't support any delayed binding, and supposes that the i915 driver registers the component immediately. This has been OK, so far, but the work-in-progress change in i915 may introduce the asynchronous binding, which effectively delays the component registration. For addressing it, implement a completion to be synced with the master binding. The timeout is set to 10 seconds which should be long enough and hopefully be not too annoying if anyone boots up a debugging session with i915 KMS turned off.

2018-07-17ALSA: hda: Make audio component support more genericTakashi Iwai4-332/+354
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 Iwai1-13/+21
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.

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>
