[PATCH v8 00/14] ALSA: hda: cirrus: Add initial DSP support and firmware loading
The CS35L41 Amplifier contains a DSP, capable of running firmware. The firmware can run algorithms such as Speaker Protection, to ensure that playback at high gains do not harm the speakers. Adding support for CS35L41 firmware into the CS35L41 HDA driver also allows us to support several extra features, such as hiberation and interrupts.
The chain adds support in stages: - General fixes to improve generalization and code re-use inside the CS35L41 HDA driver. - Add support for interrupts into the driver, which is required for complete support of the firmware. - Refactor ASoC CS35L41 code which deals with firmware to allow for code re-use inside the CS35L41 HDA driver. - Add support for loading firmware and tuning files from file system, and creating alsa controls to control it. - Support firmware load paths for different hardware systems. - Support suspend/resume in the driver when using firmware. The firmware supports hibernation, which allows the CS35L41 to drop into a low power mode during suspend. - Support the ability to unload firmware, swap and reload the firmware. This is to allow different firmware to run during calibration.
The intended use-case is to load the firmware once on boot, and the driver autmatically tries to load the firmware after it binds to the HDA driver. This behaviour can be switched off using a kconfig, if desired.
changes since v7: - Use private_data rather than private_value to save control info - Clean up alsa control memory allocation/deallocation - Remove unnecessary whitespace - Get subsystem id from codec, rather than saving it separately
changes since v6: - Fix warning by kernel test robot lkp@intel.com
changes since v5: - Fix warning by kernel test robot lkp@intel.com
changes since v4: - Fully remove tlv remnants from control add apis - Remove unnecessary debug - Rename variable to be more generic - Remove redundent length check from read/write control apis
- Use SNDRV_CTL_ELEM_IFACE_CARD for firmware load controls - Make kcontrol add/remove synchronous - Load firmware asynchronous when loading via control - Used cached controls when reloading firmware; only delete controls when removing the driver itself
- Improve kcontrol remove - Fix control write + notify - Cleanup of unnecessary code - Fix race condition when loading firmware before playback - Ensure errors are properly propogated - Fix include for Module parameters

The cs35l41 part contains a DSP which is able to run firmware. The cs_dsp library can be used to control the DSP. These controls can be exposed to userspace using ALSA controls. This library adds apis to be able to interface between cs_dsp and hda drivers and expose the relevant controls as ALSA controls.

This change alone doesn't give anything useful, unfortunately.
The above form (without prompt) is basically only to be "selected" by others. And when selected, the "depends" there is just ignored, so it's useless.
That is, a proper way would be something like:
config SND_HDA_CS_DSP_CONTROLS tristate
config SND_HDA_SCODEC_CS35L41 .... select SND_HDA_CS_DSP_CONTROLS if CS_DSP
... if you want / need to enable CONFIG_SND_HDA_CS_DSP_CONTROLS conditionally.

And now I see that the patch 4 has those selects (but select both SND_HDA_CS_DSP_CONTROLS and CS_DSP). So what we need here is to drop the superfluous "depends on CS_DSP" and mention in the description that the Kconfig will be actually enabled in the later patch.

But no need for resubmission; I fixed this locally.
So I applied up to the patch 8. At patch 9, it can't build because of the lack of ASoC side change.
Still waiting for *ANY* reaction from Mark... Sigh.

DSP controls are exposed as ALSA controls, however, some of these controls are required to be accessed by the driver. Add apis which allow read/write of these controls. The write api will also notify the ALSA control on value change.

This patch adds support for the CS35L41 DSP. The DSP allows for extra features, such as running speaker protection algorithms and hibernations.
To utilize these features, the driver must load firmware into the DSP, as well as various tuning files which allow for customization for specific models.

To be able to support different firmwares and tuning for different models, the driver needs to be able to load a different firmware and coefficient file based on its Subsystem ID.
The driver attempts to load the firmware in the following order:

CS35L41 supports hibernation during suspend when using DSP firmware. When the driver suspends it will hibernate the part, if firmware is running, and resume will wake from hibernation. CS35L41 driver will suspend/resume when requested by hda driver. Note that suspend/resume and hibernation is only supported when firmware is running.

The config sequences for running with and without firmware and DSP are different. The original behavior assumed that we would only run without DSP only in the case where firmware load failed. This meant the non-firmware sequence was written with the assumtion that various registers would be set to their default value. However, to support the ability to unload the firmware, the non-firmware register sequence must be updated to update all required registers, including values that would be defaulted, in case the firmware sequence, which could have already run, has changed their value.

From: Stefan Binding sbinding@opensource.cirrus.com
This is required to support CS35L41 calibration.
By default, speaker protection firmware will be loaded, if available. However, different firmware is required to run the calibration sequence, so it is necessary to add support to be able to unload, switch and reload firmware.
This patch adds 2 ALSA Controls for each amp: "DSP1 Firmware Load" "DSP1 Firmware Type"
"DSP1 Firmware Load" can be used to unload and load the firmware. "DSP1 Firmware Type" can be used to switch the target firmware to be loaded by "DSP1 Firmware Load"
Since loading firmware can add new ALSA controls, it is necessary to ensure the firmware loading is run asynchronously from the ALSA control itself to prevent deadlocks.
Note: When switching between firmwares, an ALSA control is only added if it has not previously existed. If it had existed previously, it will be re-enabled instead.

By default, the driver will automatically load DSP firmware for the amps, if available. Adding this option allows the autoload to be optional, which allows for different configurations.

Thanks, this version looks better than previous ones, and I'm fine to apply as is, to make things going forward. But this seems requiring the prerequisite in ASoC codec side.
Mark, could you send a PR to merge into my tree so that I can apply those series?
And, one still uncertain thing is about the handling of system suspend/resume, especially about the firmware loading work. e.g. what happens if a f/w work is in run and the system goes to suspend at the very same time? Or does the S3/S4 work in general at all?

Vitaly Rodionov (1): ALSA: hda: cs35l41: Add initial DSP support and firmware loading
Thanks, this version looks better than previous ones, and I'm fine to apply as is, to make things going forward. But this seems requiring the prerequisite in ASoC codec side.
Mark, could you send a PR to merge into my tree so that I can apply those series?
And, one still uncertain thing is about the handling of system suspend/resume, especially about the firmware loading work. e.g. what happens if a f/w work is in run and the system goes to suspend at the very same time? Or does the S3/S4 work in general at all?
Sorry for the delay, but your comments raised our attention and we wanted to run extensive testing again to make sure there is no hidden issue. No issues were found during tests. When we start FW download work we call "resume", so the resume counter should be incremented and suspend will not happen till we finish the download process.
Thanks,
Vitaly
