* rt286: add Thinkpad Helix 2 to force_combo_jack_tableYifeng Li2017-07-121-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | commit fe0dfd6358a17c79bd7d6996af7512ba452a7059 upstream. Thinkpad Helix 2 is a tablet PC, the audio is powered by Core M broadwell-audio and rt286 codec. For all versions of Linux kernel, the stereo output doesn't work properly when earphones are plugged in, the sound was coming out from both channels even if the audio contains only the left or right channel. Furthermore, if a music recorded in stereo is played, the two channels cancle out each other out, as a result, no voice but only distorted background music can be heard, like a sound card with builtin a Karaoke sount effect. Apparently this tablet uses a combo jack with polarity incorrectly set by rt286 driver. This patch adds DMI information of Thinkpad Helix 2 to force_combo_jack_table[] and the issue is resolved. The microphone input doesn't work regardless to the presence of this patch and still needs help from other developers to investigate. This is my first patch to LKML directly, sorry for CC-ing too many people here.

* ALSA: hda - set input_path bitmap to zero after moving it to new placeHui Wang2017-07-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | commit a8f20fd25bdce81a8e41767c39f456d346b63427 upstream. Recently we met a problem, the codec has valid adcs and input pins, and they can form valid input paths, but the driver does not build valid controls for them like "Mic boost", "Capture Volume" and "Capture Switch". Through debugging, I found the driver needs to shrink the invalid adcs and input paths for this machine, so it will move the whole column bitmap value to the previous column, after moving it, the driver forgets to set the original column bitmap value to zero, as a result, the driver will invalidate the path whose index value is the original colume bitmap value. After executing this function, all valid input paths are invalidated by a mistake, there are no any valid input paths, so the driver won't build controls for them.

* ALSA: hda - Fix endless loop of codec configureTakashi Iwai2017-07-052-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | commit d94815f917da770d42c377786dc428f542e38f71 upstream. azx_codec_configure() loops over the codecs found on the given controller via a linked list. The code used to work in the past, but in the current version, this may lead to an endless loop when a codec binding returns an error. The culprit is that the snd_hda_codec_configure() unregisters the device upon error, and this eventually deletes the given codec object from the bus. Since the list is initialized via list_del_init(), the next object points to the same device itself. This behavior change was introduced at splitting the HD-audio code code, and forgotten to adapt it here. For fixing this bug, just use a *_safe() version of list iteration.

* ALSA: pcm: Don't treat NULL chmap as a fatal errorTakashi Iwai2017-06-291-2/+2
| | | | | | | | | | | | | | | | | | | commit 2deaeaf102d692cb6f764123b1df7aa118a8e97c upstream. The standard PCM chmap helper callbacks treat the NULL info->chmap as a fatal error and spews the kernel warning with stack trace when CONFIG_SND_DEBUG is on. This was OK, originally it was supposed to be always static and non-NULL. But, as the recent addition of Intel LPE audio driver shows, the chmap content may vary dynamically, and it can be even NULL when disconnected. The user still sees the kernel warning unnecessarily. For clearing such a confusion, this patch simply removes the snd_BUG_ON() in each place, just returns an error without warning.

In this case, PCM substream should be aborted in packet handler. On the other hand, it should not be done in any process context. TO distinguish these two context, use 'in_interrupt()' macro. 2. Any error is detect in process context of ALSA PCM application. In this case, PCM substream should not be aborted in packet handler because PCM substream lock is acquired. The task to abort PCM substream should be done in ALSA PCM core. For this purpose, SNDRV_PCM_POS_XRUN is returned at 'struct snd_pcm_ops.pointer()'.

* drm/i915: Fix runtime PM for LPE audioVille Syrjälä2017-06-141-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 668e3b014afb66ab29e134bca7c258527273ac75 upstream. Not calling pm_runtime_enable() means that runtime PM can't be enabled at all via sysfs. So we definitely need to call it from somewhere. Calling it from the driver seems like a bad idea because it would have to be paired with a pm_runtime_disable() at driver unload time, otherwise the core gets upset. Also if there's no LPE audio driver loaded then we couldn't runtime suspend i915 either. So it looks like a better plan is to call it from i915 when we register the platform device. That seems to match how pci generally does things. I cargo culted the pm_runtime_forbid() and pm_runtime_set_active() calls from pci as well. The exposed runtime PM API is massive an thorougly misleading, so I don't actually know if this is how you're supposed to use the API or not. But it seems to work. I can now runtime suspend i915 again with or without the LPE audio driver loaded, and reloading the LPE audio driver also seems to work. Note that powertop won't auto-tune runtime PM for platform devices, which is a little annoying. So I'm not sure that leaving runtime PM in "on" mode by default is the best choice here. But I've left it like that for now at least. Also remove the comment about there not being much benefit from LPE audio runtime PM. Not allowing runtime PM blocks i915 runtime PM, which will also block s0ix, and that could have a measurable impact on power consumption.

* ASoC: Fix use-after-free at card unregistrationTakashi Iwai2017-06-141-2/+3
| | | | | | | | | | | | | | | | | | | | | commit 4efda5f2130da033aeedc5b3205569893b910de2 upstream. soc_cleanup_card_resources() call snd_card_free() at the last of its procedure. This turned out to lead to a use-after-free. PCM runtimes have been already removed via soc_remove_pcm_runtimes(), while it's dereferenced later in soc_pcm_free() called via snd_card_free(). The fix is simple: just move the snd_card_free() call to the beginning of the whole procedure. This also gives another benefit: it guarantees that all operations have been shut down before actually releasing the resources, which was racy until now.

* ALSA: timer: Fix missing queue indices reset at SNDRV_TIMER_IOCTL_SELECTTakashi Iwai2017-06-141-0/+1

Using jiffies in hdac_wait_for_cmd_dmas() to determine when to time out when interrupts are off (snd_hdac_bus_stop_cmd_io()/spin_lock_irq()) causes hard lockup so unlock while waiting using jiffies. ---<-snip->--- <0>[ 1211.603046] NMI watchdog: Watchdog detected hard LOCKUP on cpu 3 <4>[ 1211.603047] Modules linked in: snd_hda_intel i915 vgem <4>[ 1211.603053] irq event stamp: 13366 <4>[ 1211.603053] hardirqs last enabled at (13365): ... <4>[ 1211.603059] Call Trace: <4>[ 1211.603059] ? delay_tsc+0x3d/0xc0 <4>[ 1211.603059] __delay+0xa/0x10 <4>[ 1211.603060] __const_udelay+0x31/0x40 <4>[ 1211.603060] snd_hdac_bus_stop_cmd_io+0x96/0xe0 [snd_hda_core] <4>[ 1211.603060] ? azx_dev_disconnect+0x20/0x20 [snd_hda_intel] <4>[ 1211.603061] snd_hdac_bus_stop_chip+0xb1/0x100 [snd_hda_core] <4>[ 1211.603061] azx_stop_chip+0x9/0x10 [snd_hda_codec] <4>[ 1211.603061] azx_suspend+0x72/0x220 [snd_hda_intel] <4>[ 1211.603061] pci_pm_suspend+0x71/0x140 <4>[ 1211.603062] dpm_run_callback+0x6f/0x330 <4>[ 1211.603062] ? pci_pm_freeze+0xe0/0xe0 <4>[ 1211.603062] __device_suspend+0xf9/0x370 <4>[ 1211.603062] ? dpm_watchdog_set+0x60/0x60 <4>[ 1211.603063] async_suspend+0x1a/0x90 <4>[ 1211.603063] async_run_entry_fn+0x34/0x160 <4>[ 1211.603063] process_one_work+0x1f4/0x6d0 <4>[ 1211.603063] ? process_one_work+0x16e/0x6d0 <4>[ 1211.603064] worker_thread+0x49/0x4a0 <4>[ 1211.603064] kthread+0x107/0x140 <4>[ 1211.603064] ? process_one_work+0x6d0/0x6d0 <4>[ 1211.603065] ? kthread_create_on_node+0x40/0x40 <4>[ 1211.603065] ret_from_fork+0x2e/0x40 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=100419 Fixes: 38b19ed7f81ec ("ALSA: hda: fix to wait for RIRB & CORB DMA to set") Reported-by: Marta Lofstedt <marta.lofstedt@intel.com> Suggested-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jeeja KP <jeeja.kp@intel.com> Acked-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With RTlinux a race condition has been found that leads to NULL ptr crash: - On CPU 0: uni_player_irq_handler is called to treat XRUN "(player->state == UNIPERIF_STATE_STOPPED)" is FALSE so status is checked, dev_err(player->dev, "FIFO underflow error detected") is printed and then snd_pcm_stream_lock should be called to lock stream for stopping. - On CPU 1: application stop and close the stream. Issue is that the stop and shutdown functions are executed while "FIFO underflow error detected" is printed. So when CPU 0 calls snd_pcm_stream_lock, player->substream is already null.

Drop these superfluous flags for fixing the behavior. Also, the bytcr_rt5640 driver lacks of nonatomic flag in some FE definitions, which leads to the kernel Oops at suspend/resume like: BUG: scheduling while atomic: systemd-sleep/3144/0x00000003 Call Trace: dump_stack+0x5c/0x7a __schedule_bug+0x55/0x70 __schedule+0x63c/0x8c0 schedule+0x3d/0x90 schedule_timeout+0x16b/0x320 ? del_timer_sync+0x50/0x50 ? sst_wait_timeout+0xa9/0x170 [snd_intel_sst_core] ? sst_wait_timeout+0xa9/0x170 [snd_intel_sst_core] ? remove_wait_queue+0x60/0x60 ? sst_prepare_and_post_msg+0x275/0x960 [snd_intel_sst_core] ? sst_pause_stream+0x9b/0x110 [snd_intel_sst_core] ....

Each driver can utilize this abstraction to transfer MIDI messages via fixed-length payload of transaction to a certain unit address. Filling payload of the transaction is done by callback. In this callback, each driver can return negative error code, however current implementation assigns the return value to unsigned variable. This commit changes type of the variable to fix the bug.

It was introduced from the beginning, just to be "safer", in terms of avoiding the stupid bugs. However, as Ben Hutchings suggested, this timeout rather introduces a potential leak or use-after-free that was apparently fixed by the commit 2d7d54002e39 ("ALSA: seq: Fix race during FIFO resize"): for example, snd_seq_fifo_event_in() -> snd_seq_event_dup() -> copy_from_user() could block for a long time, and snd_use_lock_sync() goes timeout and still leaves the cell at releasing the pool. For fixing such a problem, we remove the break by the timeout while still keeping the warning.

The cause is that the driver manages to register two rawmidi instances with the same device number 0. This is a regression introduced since kernel 4.7. This commit fixes the regression, by fixing up device property after discovering stream formats.

After consulting with Dell, they told us this machine doesn't support microphone via headset jack, so we add a new fixup which only defines the pin 0x18 as the headset-mic.

The biggest block of changes here by volume is the sun8i-codec set, the driver was newly added in the merge window but it was realized that renaming some of the user visible controls was required so these are being pushed for v4.11 to avoid the original code appearing in a release. Otherwise it's all fairly standard bugfix stuff.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We should not be writing acknowledge controls until the firmware is running, as in the case of preloaded firmwares the DSP memory may be unaccessible to whilst in the preloaded state. This means a write to the control during this time could be lost. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>

| | |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Volatile controls should only be accessed when the firmware is active, currently however writes to these controls will succeed, but the data will be lost, if the firmware is powered down. Update this behaviour such that an error is returned the same as it is for reads. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>
