Fireface 400 and 800 have the same mechanism to decide address to which asynchronous transactions are sent for MIDI messages, however they use different registers for controllers to notify higher 4 byte of the address. This commit adds a model-specific parameter to represent the address. Additionally, it corrects some comments. I note that these two models have a difference to enable/disable the transaction.

As long as investigating packet dumps from Fireface 400/800, a register to receive asynchronous transactions for MIDI messages is the same. For Fireface 800, minor register is used. This commit declares macros for the transactions and obsoletes model-specific parameters. Signed-off-by:

In an initial commit, 'SYNC_STATUS' register is referred to get clock configuration, however this is wrong, according to my local note at hand for reverse-engineering about packet dump. It should be 'CLOCK_CONFIG' register. Actually, ff400_dump_clock_config() is correctly programmed. This commit fixes the bug.

Users reported a mute LED regression on Lenovo X1 Carbon, the root cause is we applied the fixup of ALC285_FIXUP_LENOVO_HEADPHONE_NOISE to this machine, then the machine can't apply the fixup of ALC269_FIXUP_THINKPAD_ACPI anymore.

Extend some structs to add the support for jack button changes. Now snd_hda_jack_add_kctl() receives two more arguments: the jack type and the jack keymaps. Both are optional, and when zero are passed, the function behaves just like before. For reporting button state changes, you'd need to update jack->button_state bits accordingly, typically in the jack callback. Then the value OR'ed with button_state and the jack plug state is passed to snd_jack_report(). Note that currently the code assumes only the one-shot button events, i.e. it tries to send the button release soon after sending the button event. If a driver really supports the button release handling by itself, we may need to introduce some flag to control this behavior in future. Signed-off-by: -

If a USB sound card reports 0 interfaces, an error condition is triggered and the function usb_audio_probe errors out. In the error path, there was a use-after-free vulnerability where the memory object of the card was first freed, followed by a decrement of the number of active chips. Moving the decrement above the atomic_dec fixes the UAF. [ The original problem was introduced in 3.1 kernel, while it was developed in a different form.

We've got a regression report for some Thinkpad models (at least T570s) which shows the too low speaker output volume. The bisection leaded to the commit 61fcf8ec ("ALSA: hda/realtek - Enable Thinkpad Dock device for ALC298 platform"), and it's basically adding the two pin configurations for the dock, and looks harmless. The real culprit seems, though, that the DAC assignment for the speaker pin is implicitly assumed on these devices, i.e. pin NID 0x14 to be coupled with DAC NID 0x03. When more pins are configured by the commit above, the auto-parser changes the DAC assignment, and this resulted in the regression. As a workaround, just provide the fixed pin / DAC mapping table for this Thinkpad fixup function. It's no generic solution, but the problem itself is pretty much device-specific, so must be good enough.

Commit 67ec1072 ("ALSA: pcm: Fix rwsem deadlock for non-atomic PCM stream") fixes deadlock for non-atomic PCM stream. But, This patch causes antother stuck. If writer is RT thread and reader is a normal thread, the reader thread will be difficult to get scheduled. It may not give chance to release readlocks and writer gets stuck for a long time if they are pinned to single cpu. The deadlock described in the previous commit is because the linux rwsem queues like a FIFO. So, we might need non-FIFO writelock, not non-block one. My suggestion is that the writer gives reader a chance to be scheduled by using the minimum msleep() instaed of spinning without blocking by writer. Also, The *_nonblock may be changed to *_nonfifo appropriately to this concept. In terms of performance, when trylock is failed, this minimum periodic msleep will have the same performance as the tick-based schedule()/wake_up_q(). [ Although this has a fairly high performance penalty, the relevant code path became already rare due to the previous commit ("ALSA: pcm: Call snd_pcm_unlink() conditionally at closing"). That is, now this unconditional msleep appears only when using linked streams, and this must be a rare case. So we accept this as a quick workaround until finding a more suitable one -- tiwai ] Fixes: 67ec1072 ("ALSA: pcm: Fix rwsem deadlock for non-atomic PCM stream") Suggested-by:

Currently the PCM core calls snd_pcm_unlink() always unconditionally at closing a stream. However, since snd_pcm_unlink() invokes the global rwsem down, the lock can be easily contended. More badly, when a thread runs in a high priority RT-FIFO, it may stall at spinning. Basically the call of snd_pcm_unlink() is required only for the linked streams that are already rare occasion. For normal use cases, this code path is fairly superfluous. As an optimization (and also as a workaround for the RT problem above in normal situations without linked streams), this patch adds a check before calling snd_pcm_unlink() and calls it only when needed.

By default HDA sound card is registered with shortname "tegra-hda". Same driver is used across tegra platforms and it is necessary to distinguish between platforms to use platform specific settings from userspace. One such example is, hdmi port on different platforms use different alsa pcm device ID. For hdmi playback to work it should open correct pcm device depending on the platform. This patch applies shortname from first compatible string provided in root node of device tree. Userspace then can use this card name to apply specific settings. Signed-off-by:

Since we've switched to the LED trigger for binding with HD-audio, we can drop the exported function as well as the whole linux/thinkpad_acpi.h. The own TPACPI_LED_MUTE and TPACPI_LED_MICMUTE definitions are replaced with the identical ones for LEDS, i.e. LED_AUDIO_MUTE and LED_AUDIO_MICMUTE, respectively. They are no longer needed as referred only locally. Acked-by:

Now all relevant platform drivers are providing the LED audio trigger, we can switch the mute LED control with the LED trigger, finally. For the mic-mute LED trigger, a common fixup function, snd_hda_gen_fixup_micmute_led(), is provided to be called for the corresponding quirk entries. This sets up the capture sync hook with ledtrig_audio_set() call appropriately. For the mute LED trigger, which is done currently only for thinkpad_acpi, the call is replaced with ledtrig_audio_set() as well. Overall, the beauty of the new implementation is that the whole ugly bindings with request_symbol() are dropped, and also that it provides more flexibility to users. One potential behavior change by this patch is that the mute LED enum may be created on machines that actually have no LED device. In the former code, we did test-call and abort binding if the test failed. But with the LED-trigger binding, this test isn't possible, and the actual check is done in the LED class device side. So it's the downside of simpleness. Also, note that the HD-audio codec driver doesn't select CONFIG_LEDS and co by itself. It's supposed to be selected by the platform drivers instead. Acked-by:

In the upcoming change, the binding of audio mute / mic-mute LED controls will be switched with LED trigger. This patch is the last piece of preparation: adding the audio mute / mic-mute LED class devices to thinkpad_acpi driver. Two devices, platform::mute and platform::micmute, will be added for controlling the mute LED and mic-mute LED, respectively. The new prefix "platform" is the suggestion by upstream for indicating the generic laptop attribute. Also this selects CONFIG_LEDS_TRIGGERS and CONFIG_LEDS_TRIGGERS_AUDIO unconditionally. Strictly speaking, these aren't 100% mandatory, but leaving these manual selections would lead to a functional regression easily once after converting from the dynamic symbol binding to the LEDs trigger in a later patch.

This patch adds the LED trigger support for audio mic-mute control. As of this patch, the LED device isn't tied with the audio driver, and can be changed via user-space at "platform::micmute" sysfs entry. (This new prefix "platform" is the agreement among people for indicating the generic laptop / system-wide attribute.) The binding with HD-audio is still done via the existing exported dell_micmute_led_set(). It will be replaced with the LED trigger binding in later patches. Also this selects CONFIG_LEDS_TRIGGERS and CONFIG_LEDS_TRIGGERS_AUDIO unconditionally. Strictly speaking, these aren't 100% mandatory, but leaving these manual selections would lead to a functional regression easily once after converting from the dynamic symbol binding to the LEDs trigger in a later patch.
