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. sst-defconfig lists all the options for the SST driver. hdaudio-defconfig lists all the options for HDaudio codec support

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

cd <your kernel>
make defconfig

Then select one of the three options

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

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

Enjoy!
