Stopping of one stream is killing the other stream when they are running simultaneously. This is because, IER register is cleared which disables I2S and overrides any other block enables. Clearing IER register only when all streams on a channel are disabled, fixes the issue. Signed-off-by:

Multiple Intel ASoC machine drivers repeat the same pattern in their .late_probe() methods: they first check whether the common HDMI codec driver is used, if not, they proceed by linking the legacy HDMI driver to each HDMI port. While doing that they use some inconsistent code: 1. after the loop they check, whether the list contained at least one element and if not, they return an error. However, the earlier code to use the common HDMI driver uses the first element of the same list without checking. To fix this we move the check to the top of the function. 2. some of those .late_probe() implementations execute code, only needed for the common HDMI driver, before checking, whether the driver is used. Move the code to after the check. 3. Some of those functions also perform a redundant initialisation of the "err" variable. This patch fixes those issues. Signed-off-by:

Check if DMA pages were successfully allocated in initialization before calling free. For many types of memory (like sgbufs) the extra free is harmless, but not all backends track allocation state, so add an explicit check. Signed-off-by:

The initial intent of releasing resources in the .remove does not work well with HDaudio codecs. If the probe_continue() fails in a work queue, e.g. due to missing firmware or authentication issues, we don't release any resources, and as a result the kernel oopses during suspend operations. The suggested fix is to release all resources during errors in probe_continue(), and use fw_state to track resource allocation state, so that .remove does not attempt to release the same hardware resources twice. PM operations are also modified so that no action is done if DSP resources have been freed due to an error at probe. Reported-by:

It is possible to create invalid topology that will cause a kernel Oops when trying to allocate buffers for a NULL substream. Specifically such an Oops was caused by a topology, where a DAI on a capture pipeline was referencing the PCM ID from a playback pipeline. Fix the Oops by explicitly checking for NULL. Signed-off-by:

Change HDA probe behaviour slightly so that i915 power is not turned off if i915 audio codecs are found in the initial probe done by SOF Intel driver, and power is kept on until HDA codec driver probe runs. This will reduce number of mode sets on platforms with low minimum CDCLK (like GLK) and brings the SOF probe sequence closer to legacy HDA driver in terms of i915 audio codec power management.

The current interface to control i915 display power is misleading. The hda_codec_i915_get() and hda_codec_i915_put() names suggest a refcounting based interface. This is confusing as no refcounting is done and the underlying HDAC library interface does not support refcounts eithers. Clarify the code by replacing the functions with a single hda_codec_i915_display_power() that is aligned with snd_hdac_display_power(). Signed-off-by:

Commit 08df0d9a ("ASoC: max98090: revert "ASoC: max98090: fix lockdep warning"") provided a good rationale for removing separate lock for the SHDN register access. However it restored the lockdep warning during the system boot. To silence the lockdep warning, mark the mutex taken in the max98090_shdn_save() function with the lockdep class dedicated for the runtime DAPM operations: SND_SOC_DAPM_CLASS_RUNTIME. This finally fixes the following lockdep warning observed on Exynos4412-based Odroid U3 board: ====================================================== WARNING: possible circular locking dependency detected 5.5.0-rc7-next-20200123 #7329 Not tainted ------------------------------------------------------ alsactl/1105 is trying to acquire lock: ed4f7cf4 (&card->dapm_mutex){+.+.}, at: max98090_shdn_save+0x1c/0x28 but task is already holding lock: edb8d49c (&card->controls_rwsem){++++}, at: snd_ctl_ioctl+0xcc/0xbb8 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (&card->controls_rwsem){++++}: snd_ctl_add_replace+0x3c/0x84 dapm_create_or_share_kcontrol+0x24c/0x2e0 snd_soc_dapm_new_widgets+0x308/0x594 snd_soc_bind_card+0x834/0xa94 devm_snd_soc_register_card+0x34/0x6c odroid_audio_probe+0x288/0x34c platform_drv_probe+0x6c/0xa4 really_probe+0x200/0x48c driver_probe_device+0x78/0x1f8 bus_for_each_drv+0x74/0xb8 __device_attach+0xd4/0x16c bus_probe_device+0x88/0x90 deferred_probe_work_func+0x3c/0xd0 process_one_work+0x230/0x7bc worker_thread+0x44/0x524 kthread+0x130/0x164 ret_from_fork+0x14/0x20 0x0 -> #0 (&card->dapm_mutex){+.+.}: lock_acquire+0xe8/0x270 __mutex_lock+0x9c/0xb18 mutex_lock_nested+0x1c/0x24 max98090_shdn_save+0x1c/0x28 max98090_put_enum_double+0x20/0x40 snd_ctl_ioctl+0x190/0xbb8 ksys_ioctl+0x484/0xb10 ret_fast_syscall+0x0/0x28 0xbede0564 other info that might help us debug this: Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&card->controls_rwsem); lock(&card->dapm_mutex); lock(&card->controls_rwsem); lock(&card->dapm_mutex); *** DEADLOCK *** 1 lock held by alsactl/1105: #0: edb8d49c (&card->controls_rwsem){++++}, at: snd_ctl_ioctl+0xcc/0xbb8 stack backtrace: CPU: 2 PID: 1105 Comm: alsactl Not tainted 5.5.0-rc7-next-20200123 #7329 Hardware name: Samsung Exynos (Flattened Device Tree) [<c01126f0>] (unwind_backtrace) from [<c010e1e8>] (show_stack+0x10/0x14) [<c010e1e8>] (show_stack) from [<c0b5234c>] (dump_stack+0xb4/0xe0) [<c0b5234c>] (dump_stack) from [<c018a610>] (check_noncircular+0x1ec/0x208) [<c018a610>] (check_noncircular) from [<c018ca2c>] (__lock_acquire+0x1210/0x25ec) [<c018ca2c>] (__lock_acquire) from [<c018e728>] (lock_acquire+0xe8/0x270) [<c018e728>] (lock_acquire) from [<c0b71928>] (__mutex_lock+0x9c/0xb18) [<c0b71928>] (__mutex_lock) from [<c0b723c0>] (mutex_lock_nested+0x1c/0x24) [<c0b723c0>] (mutex_lock_nested) from [<c086097c>] (max98090_shdn_save+0x1c/0x28) [<c086097c>] (max98090_shdn_save) from [<c08613f8>] (max98090_put_enum_double+0x20/0x40) [<c08613f8>] (max98090_put_enum_double) from [<c0833f20>] (snd_ctl_ioctl+0x190/0xbb8) [<c0833f20>] (snd_ctl_ioctl) from [<c02cae14>] (ksys_ioctl+0x484/0xb10) [<c02cae14>] (ksys_ioctl) from [<c0101000>] (ret_fast_syscall+0x0/0x28) Exception stack(0xed331fa8 to 0xed331ff0) ...

However, snd_soc_dapm_put_enum_double() in max98090_dapm_put_enum_double() acquires the dapm_mutex again which cause a deadlock. Use snd_soc_dapm_put_enum_double_locked() instead to fix the deadlock.

Commit 2dc98af6 ("ASoC: max98090: fix lockdep warning") introduced a helpful-less small lock: shdn_lock. Reverts the commit. Reasons: 1. Lockdep should not be happy by either the original or current code. From lockdep's point of view, there is a lock inversion anyway. Let d = dapm_mutex, c = controls_rwsem, s = shdn_lock, From the reported calling stack: lock acquisition order of snd_soc_register_card() is: d -> c. > snd_ctl_add_replace+0x3c/0x84 > dapm_create_or_share_kcontrol+0x24c/0x2e0 > snd_soc_dapm_new_widgets+0x308/0x594 > snd_soc_bind_card+0x80c/0xad4 > devm_snd_soc_register_card+0x34/0x6c If calling snd_soc_dapm_put_enum_double() in kcontrol's put (e.g. SOC_DAPM_ENUM_EXT), lock acquisition order is: c -> d. Note that, snd_soc_dapm_put_enum_double() acquires d. The possible lock inversion is always there if registering sound card and putting mixer control happen at the same time. In fact, it never happens because the control device don't show up to the userspace until the sound card build success. Commit 2dc98af6 ("ASoC: max98090: fix lockdep warning") changes the order to: c -> s -> d. The lock inversion is still there. 2. Commit 62d5ae4c ("ASoC: max98090: save and restore SHDN when changing sensitive registers SHDN bit") designed to use dapm_mutex to protect SHDN bit. Use a separate lock breaks the protection. DAPM changes SHDN bit automatically when it finds the path. Thus, any code wants to change the SHDN bit, need to acquire the dapm_mutex first. > SND_SOC_DAPM_SUPPLY("SHDN", M98090_REG_DEVICE_SHUTDOWN, > M98090_SHDNN_SHIFT, 0, NULL, 0), Fixes: 2dc98af6 ("ASoC: max98090: fix lockdep warning") Signed-off-by:

Now, snd_soc_dai_driver::bus_control is used for how to resume. But, no driver which has bus_control has DAI driver suspend/resume support. This patch removes pointless bus_control from ALSA SoC. Signed-off-by:

Kuninori Morimoto authored
Historically, CPU and Codec were implemented different, but now it is merged as Component. ALSA SoC is supporting suspend/resume at DAI and Component level. The method is like below. 1) Suspend/Resume all CPU DAI if bus-control was 0 2) Suspend/Resume all Component 3) Suspend/Resume all CPU DAI if bus-control was 1 Historically 2) was Codec special operation. Because CPU and Codec were merged into Component, CPU suspend/resume has 3 chance to suspend(= 1/2/3), but Codec suspend/resume has 1 chance (= 2). Here, DAI side suspend/resume is caring bus-control, but no driver which is supporting suspend/resume is setting bus-control. This means 3) was never used. Here, used parameter for suspend/resume component->dev and dai->dev are same pointer. For that reason, we can merge DAI and Component suspend/resume. One note is that we should use 2), because it is caring BIAS level. This patch removes 1) and 3). Signed-off-by:

There is no big difference at implementation for .suspend/.resume between DAI driver and Component driver. But because some driver is using DAI version, thus ALSA SoC needs to keep supporting it, hence, framework becoming verbose. If we can switch all DAI driver .suspend/.resume to Component driver, we can remove verbose code from ALSA SoC. Driver is getting its private data via dai->dev. But dai->dev and component->dev are same dev, thus, we can convert these. For same reason, we can convert dai->active to component->active if necessary. Signed-off-by:
