kconfig

kconfig fragments for SOF development

The base-defconfig is intended to provide basic support for all platforms currently used for SOF development, including:

• boot
• i915/display
• USB (w/ Ethernet dongles)
• Ethernet
• WiFi

sof-defconfig lists all the options for SOF which can be enabled by distros sof-dev-defconfig lists all SOF developer options which should not be enabled by distros. This file in included in all SOF CI configurations. sst-defconfig lists all the options for the SST driver. hdaudio-defconfig lists all the options for HDaudio codec support. mach-driver-defconfig lists all the optiosn for SOF enabled machine driver support. soundwire-defconfig lists all the options for SoundWire support.

Those fragments are supposed to be applied on top of a default kernel configuration.

cd <your kernel>
make defconfig

The following options are some example how to use defconfigs:

• HDA

scripts/kconfig/merge_config.sh .config <PATH>/kconfig/base-defconfig <PATH>/kconfig/hdaudio-codecs-defconfig

• SST

scripts/kconfig/merge_config.sh .config <PATH>/kconfig/base-defconfig <PATH>/kconfig/sst-defconfig <PATH>/kconfig/hdaudio-codecs-defconfig

• SOF-NOCODEC: SOF in nocodec debug mode

scripts/kconfig/merge_config.sh .config <PATH>/kconfig/base-defconfig <PATH>/kconfig/sof-defconfig <PATH>/kconfig/nocodec-defconfig

• SOF-DEFAULT: SOF support with I2S, HDA and SDW support with machine drivers

scripts/kconfig/merge_config.sh .config <PATH>/kconfig/base-defconfig <PATH>/kconfig/sof-defconfig <PATH>/kconfig/mach-driver-defconfig <PATH>/kconfig/hdaudio-codecs-defconfig <PATH>/kconfig/soundwire-defconfig

• fuzzing test, for example on SOF-DEFAULT:

scripts/kconfig/merge_config.sh .config <PATH>/kconfig/base-defconfig <PATH>/kconfig/sof-defconfig <PATH>/kconfig/mach-driver-defconfig <PATH>/kconfig/hdaudio-codecs-defconfig <PATH>/kconfig/soundwire-defconfig <PATH>/kconfig/memory-debug-defconfig <PATH>/kconfig/lock-stall-defconfig <PATH>/kconfig/fuzz-defconfig

Or you can generate above pre-defined kconfig with scripts:

<PATH>/kconfig/kconfig-hda.sh
<PATH>/kconfig/kconfig-sst.sh
<PATH>/kconfig/kconfig-sof-nocodec.sh
<PATH>/kconfig/kconfig-sof-default.sh

Note that the last two options include developer options not suitable for distros.

then build as usual

make -j8

Additional fragments:

• atom-defconfig: Atom-specific optimization
• compile-test-defconfig: turn on compilation checks
• debug-defconfig: turn on debug hooks
• edison-defconfig: configuration for Edison provided by Andy Shevchenko
• igb-tsn-defconfig: configuration for I210/I211
• memory-debug-defconfig: KASAN and friends debug
• nocodec-defconfig: interface-level tests for SSP/DMIC
• nopm-defconfig: turn off PM completely
• notrace-debugfs-defconfig: remove debugfs, useful for error handling
• snd-drm-modules-defconfig: build sound and DRM as modules
• up-defconfig: config for up board
• telemetry-debugfs-defconfig: config snippet for S0ix telemetry debugfs support

Enjoy!
