ASoC: SOF: add Kconfig option for strict ABI checks (73affae2) · Commits · 戴 / test

When the kernel is more recent than firmware files, it will always behave in backwards-compatible ways. Add optional behavior to check if the kernel is older than the firmware files, so that the kernel fails early instead of attempting to use new functionality it does not support. Signed-off-by:

		This option enables strict ABI checks for firmware and topology
		files.
		When these files are more recent than the kernel, the kernel
		will handle the functionality it supports and may report errors
		during topology creation or run-time usage if new functionality
		is invoked.
		This option will stop topology creation and firmware load upfront.
		It is intended for SOF CI/releases and not for users or distros.

		If you are not involved in SOF releases and CI development
