No idea what you mean by saying standard kernel philosophy but people do add code that might be useful later. Some examples are: -- ftrace subsystem; -- commit eb2415854f3ba7d95c4f30d259f6f598ab604616 -- commit 78723fe309f189ee4010d5b7a55f6a14644a40c2 (if you so fancy about debug printk) We can probably find more examples. > Please consider adding that print when you submit support for > e850. Support for e850 was already sent: https://lore.kernel.org/linux-samsung-soc/20260513-exynos850-acpm-firmware-= support-v1-0-3858d097e433@linaro.org/ It doesn't matter now. Krzysztof already accepted ACPM TMU with error conversion variant for gs101 only. It will be nice to see ACPM that is more generic towards Exynos/Samsung SoCs rather than gs. BR, Alexey.
