The rt5677 driver writes to the IRQ control register within the IRQ handler in order to flip the polarity of the interrupts that have been signalled. If an interrupt fires in the interval between the regmap_read and the regmap_write, it will not trigger a new call to rt5677_irq. Add a bounded loop to rt5677_irq that keeps checking interrupts until none are seen, so that any interrupts that are signalled in that interval are correctly handled. Signed-off-by:

The rt5677 jack detection function has a requirement that the polarity of an interrupt be flipped after it fires in order to clear the interrupt. This patch implements an irq_chip with irq_domain directly instead of using regmap-irq, so that interrupt source line polarities can be flipped in the irq handler. The reason that this patch does not add this feature within regmap-irq is that future patches will add hotword detection support to this irq handler. Those patches will require adding additional logic that would not make sense to have in regmap-irq. Signed-off-by:

A snd_soc_dai_link_component is allocated and associated with the first link, so when the code tries to assign the of_node of the second link's "cpu" member it dereferences a NULL pointer. Fix this by moving the allocation and assignement of snd_soc_dai_link_components into the loop, giving us one pair per link.

commit c16015f3 ("ASoC: rsnd: add .get_id/.get_id_sub") introduces rsnd_ctu_id which calcualates and gives the main Device id of the CTU by dividing the id by 4. rsnd_mod_id uses this interface to get the CTU main Device id. But this commit forgets to revert the main Device id calcution previously done in rsnd_ctu_probe_ which also divides the id by 4. This path corrects the same to get the correct main Device id. The issue is observered when rsnd_ctu_probe_ is done for CTU1 Fixes: c16015f3 ("ASoC: rsnd: add .get_id/.get_id_sub") Signed-off-by:

This patch moves the code to select the gpios for jack detection from rt5677_probe to rt5677_init_irq (called from rt5677_i2c_probe). It also sets some registers to fix bugs related to jack detection, and adds some constants and comments to make it easier to understand what certain register settings are controlling. Signed-off-by:

The rt5677 driver uses ACPI-style property names to read from the device API. However, these do not match the property names in _DSD used on the Chromebook Pixel 2015, which are closer to the Device Tree style. Unify the two functions for reading from the device API so that they try ACPI-style names first and fall back to the DT names on error. With this patch, plugging and unplugging the headphone jack switches between headphones and speakers automatically. Signed-off-by:

Compile-testing without PCI just causes warnings: sound/soc/sof/sof-pci-dev.c:330:13: error: 'sof_pci_remove' defined but not used [-Werror=unused-function] static void sof_pci_remove(struct pci_dev *pci) ^~~~~~~~~~~~~~ sound/soc/sof/sof-pci-dev.c:230:12: error: 'sof_pci_probe' defined but not used [-Werror=unused-function] static int sof_pci_probe(struct pci_dev *pci, ^~~~~~~~~~~~~ I tried to fix this in a way that would still allow compile tests, but it got too ugly, so this just reverts the patch that allowed it in the first place. Most architectures do allow enabling PCI, so the value of the COMPILE_TEST alternative was not very high to start with.

We should use irq disabled mode when read/write hda registers from thread context, as we need to hold the same bus->reg_lock in interrupt context hda_dsp_stream_interrupt(), otherwise, when we are holding the lock in hda_dsp_stream_hw_free() and the interrupt arrives, we will get deadlock in the interrupt handler. Error logs like this: [ 5.603606] CPU0 [ 5.603606] ---- [ 5.603607] lock(&(&bus->reg_lock)->rlock); [ 5.603608] <Interrupt> [ 5.603609] lock(&(&bus->reg_lock)->rlock); [ 5.603610] *** DEADLOCK *** [ 5.603611] 2 locks held by pulseaudio/2329: [ 5.603612] #0: 000000005fcf26c6 (&card->mutex/1){+.+.}, at: dpcm_fe_dai_hw_free+0x2b/0x110 [snd_soc_core] [ 5.603619] #1: 00000000ef369faf (&rtd->pcm_mutex){+.+.}, at: soc_pcm_hw_free+0x2e/0x1c0 [snd_soc_core] The fix is simple, let's switch to use spin_lock/unlock_irq().

Modify the stream interrupt handler to always wake up the IRQ thread if the status register is valid. The IRQ thread performs the check for stream interrupts and RIRB interrupts in a loop to handle the case of missed interrupts when an unsolicited response from the codec is received just before the stream interrupt handler is completed.

Host and link DMA are decoupled during FE hw_params. So, they must be coupled in hw_free if the link DMA channel is idle. Signed-off-by:

Paused streams do not get suspended when the system enters S3. So, clear and release link DMA channel for such streams in the hda_dsp_set_hw_params_upon_resume() callback. Also, invalidate the link DMA channel in the DAI config before restoring the dai config upon resume. Also, modify the signature for the set_hw_params_upon_resume() op to return an int. Signed-off-by:

Due to the HW programming sequence requirement that the host and link DMA channels need to be coupled/decoupled during pcm hw_params, the host DMA channel corresponding to the link DMA channel in use for hostless streams needs to be reserved. This is achieved by adding a host_reserved flag in the sof_intel_hda_stream structure which is checked when assigning a host DMA channel. Signed-off-by:

Ranjani Sridharan authored
The recommended HDA HW programming sequence for setting the DMA format requires that the link DMA and host DMA channels be coupled before setting the format. This change means that host DMA or link DMA channels be reserved even if only one is used. Statically assigned link DMA channels would mean that all the corresponding host DMA channels will need to be reserved, leaving only a few channels available at run-time. So, the suggestion here is to switch to dynamically assigning both host DMA channels and link DMA channels are run-time. The host DMA channel is assigned when the pcm is opened as before. While choosing the link DMA channel, if the host DMA channel corresponding to the link DMA channel is already taken, the proposed method checks to make sure that the BE is connected to the FE that has been assigned this host DMA channel. Once the link DMA channel is assigned, an IPC is sent to the DSP to set the link DMA channel. The link DMA channel is freed during hw_free() and also in the SUSPEND trigger callback. It will be re-assigned when hw_params are set upon resume. Signed-off-by:

The settling time of DMIC DC level is both platform and used microphone model specific. The unmute gain ramp is used to conceal most of the large DC level seen in beginning of capture. This patch adds into the DMIC DAI IPC struct a new field called unmute_ramp_time and a new token SOF_TKN_INTEL_DMIC_UNMUTE_RAMP_TIME. The value is the ramp length in milliseconds (ms). The ABI minor version is incremented for this backwards compatible change. Signed-off-by:

As part of the suspend flow, a context save IPC message is sent to the firmware before powering down the DSP. If errors are met, the suspend flow is aborted with current code. Change the behaviour such that if firmware returns -EBUSY or -EAGAIN, return the error codes to PM core as before. The device is left in active state in this case. If other errors are reported, print a warning but do not block the suspend flow. As per interface specification, no valid error can be returned in this scenario. If the hardware has hit a fatal error and is not able to respond successfully, best recovery method is to proceed with suspend and power off the DSP. Signed-off-by:
