2020-09-17ASoC: SOF: Intel: hda: reduce verbosity of boot error logsPierre-Louis Bossart1-0/+8
Previous commits reduced the verbosity of errors during boot iterations, but there are still a couple remaining which generate false positives. Errors should only be logged when after last attempt to download firmware failed. Duplicating logs and assigning them different levels based on the iteration number isn't really elegant, use macro as suggested by Guennadi.

2020-08-26ASoC: SOF: loader: Add debug box regionIulian Olaru1-0/+1
This patch adds an IPC initiated debug box region in the snd_sof_dev structure, defined in soc/sof/sof-priv.h. It is initialized at loading, in the sof_get_windows function from soc/sof/loader.c, in a similar manner with the stream box and host box. This region is useful because the firmware will put an error message here so the kernel can read it in case of a dsp oops.

2020-02-11ASoC: SOF: Intel: cnl: Implement feature to support DSP D0i3 in S0Ranjani Sridharan1-0/+3
This patch implements support for DSP D0i3 when the system is in S0. The basic idea is to schedule a delayed work after every successful IPC TX that checks if there are only D0I3-compatible streams active and if so transition the DSP to D0I3. With the introduction of DSP D0I3 in S0, we need to ensure that the DSP is in D0I0 before sending any new IPCs. The exception for this would be the compact IPCs that are used to set the DSP in D0I3/D0I0 states.

2020-02-11ASoC: SOF: Move DSP power state transitions to platform-specific opsRanjani Sridharan1-10/+8
The DSP device substates such as D0I0/D0I3 are platform-specific. Therefore, the d0_substate field of struct snd_sof_dev is replaced with the dsp_power_state field which represents the current state of the DSP. This field holds both the device state and the platform-specific substate values. With the DSP device substates being platform-specific, the DSP power state transitions need to be performed in the platform-specific suspend/resume ops as well. In order to achieve this, the ops signature has to be modified to pass the target device state as an argument. The target substate will be determined by the platform-specific ops before performing the transition. For example, in the case of the system suspending to S0IX, the top-level SOF device suspend callback needs to only determine if the DSP will be entering D3 or remain in D0. The target substate in case the device needs to remain in D0 (D0I0 or D0I3) will be determined by the platform-specific suspend op. With the addition of the extended set of power states for the DSP, the set_power_state op for HDA platforms has to be extended to handle only the appropriate state transitions. So, the implementation for the Intel HDA platforms is also modified.

Also, add a helper to determine the target DSP power state based on the system suspend target.

2019-12-18ASoC: SOF: Introduce state machine for FW bootRanjani Sridharan1-1/+10
Add a state machine for FW boot to track the different stages of FW boot and replace the boot_complete field with fw_state field in struct snd_sof_dev. This will be used to determine the actions to be performed during system suspend. One of the main motivations for adding this change is the fact that errors during the top-level SOF device probe cannot be propagated and therefore suspending the SOF device normally during system suspend could potentially run into errors. For example, with the current flow, if the FW boot failed for some reason and the system suspends, the SOF device suspend could fail because the CTX_SAVE IPC would be attempted even though the FW never really booted successfully causing it to time out. Another scenario that the state machine fixes is when the runtime suspend for the SOF device fails and the DSP is powered down nevertheless, the CTX_SAVE IPC during system suspend would timeout because the DSP is already powered down.

2019-12-09ASoC: SOF: Make creation of machine device from SOF core optionalDaniel Baluta1-0/+11
Currently, SOF probes machine drivers by creating a platform device and passing the machine description as private data. This is driven by the ACPI restrictions. Ideally, ACPI tables should contain the description for the machine driver. This is not possible because ACPI tables are frozen and used on multiple OS-es (e.g Windows). In the case of Device Tree we don't have this restriction, so we choose to probe the machine drivers by creating a DT node as is the standard ALSA way. This patch makes the probing of machine drivers from SOF core optional allowing for Device Tree platforms to decouple the SOF core from machine driver probing. Along with this, it also consolidates the machine driver selection for Intel platforms by defining optional ops for selecting the machine driver based on the ACPI match for HDA and non-HDA platforms and setting the mach params.

2019-10-01ASoC: SOF: trace: move to opt-in with Kconfig and module parameterPierre-Louis Bossart1-4/+9
In a number of debug cases, the DMA-based trace can add problems (e.g. with HDaudio channel allocation). It also generates additional traffic on the bus and if the DMA handling is unreliable will prevent audio use-cases from working normally. Using the trace also requires tools to be installed on the target. The trace can be instead handled as dynamic debug. We can use a Kconfig to force the trace to be enabled in all cases, or use a module parameter to enable it on a need-basis, e.g. by setting "options snd_sof sof_debug=0x1" in a /etc/modprobe.d file.

2019-08-09ASoC: SOF: Intel: byt: Refactor fw ready / mem windows creationDaniel Baluta1-0/+2
There is a lot of duplicate code when processing IPC firmware ready notification and creating memory windows. First step in reducing the code duplication is to introduce generic functions: * sof_get_windows * sof_fw_ready that will replace, in the first step, the specific implementation related to baytrail related platforms: * byt_get_windows * byt_fw_ready So we are basically moving code from intel/byt.c to loader.c keeping in mind that mbox_offset is a per platform constant so we need to use newly introduced snd_sof_dsp_get_mailbox_offset / snd_sof_dsp_get_window_offset in order to get the correct mbox offset / window offset value. Also, bar is a per platform constant so we use snd_sof_dsp_get_bar_index instead of the hardcoded BYT_DSP_BAR.

2019-08-01ASoC: SOF: no need to check return value of debugfs_create functionsGreg Kroah-Hartman1-1/+0
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Also, if a debugfs call fails, userspace is notified with an error in the log, so no need to log the error again. Because we no longer need to check the return value, there's no need to save the dentry returned by debugfs. Just use the dentry in the file pointer if we really need to figure out the "name" of the file being opened.

2019-07-23ASoC: SOF: Introduce snd_sof_dsp_get_bar_index opsDaniel Baluta1-0/+3
FW encapsulates information about section types (e.g DRAM, IRAM) inside module block header. This information can be used in order to correctly load the section to the appropriate place in memory. SOF Linux driver needs to know for each platform how to map the section type with the corresponding memory BAR. So, this patch introduces get_bar_index, a new operation inside snd_sof_dsp_ops. Intel platforms, usually load all the section in a contiguous memory area (usually denoted by sdev->mmio_bar) so things are relatively simple there. Anyhow, on i.MX8 IRAM and DRAM for example are mapped to distinct BARs. By default, if no get_bar function is provided the core implementation will always return sdev->mmio_bar so that there will be no need for a change to existing Intel code.

2019-07-23ASoC: SOF: reset DMA state in prepareKai Vehmanen1-1/+1
When application goes through SUSPEND/STOP->PREPARE->START cycle, we should always reprogram the SOF device to start DMA from a known state so that hw_ptr/appl_ptrs remain valid. This is expected by ALSA core as it resets the buffer state as part of prepare (see snd_pcm_do_prepare()). Fix the issue by forcing reconfiguration of the FW with STREAM_PCM_PARAMS in prepare(). Use combined logic to handle prepare and the existing flow to reprogram hw-params after system suspend. Without the fix, first call to pcm pointer() will return an invalid hw_ptr and application may immediately observe XRUN status, unless "start_threshold" SW parameter is set to maximum value by the application.

2019-06-17ASoC: SOF: Intel: hda: assign link DMA channel at run-timeRanjani Sridharan1-0/+2
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.
