Linux kernel update on flex 5g

[ValkyrieStella]

Adding this issue here since I'm unable to open an issue on your linux repository.
I have attempted updating the Linux kernel per instructions posted on the README. I have tried branches laptops-5.13, laptops-5.14, and laptpos-5.15 on the Lenovo Flex 5g. All three have yielded the same error during the second make command. output below:

The build log says you are building a 5.1.0 kernel?

[ValkyrieStella]

It shouldn't be.. I ran git checkout -b laptops-5.13 and make laptop_defconfig

[shawnguo2]

Well, there is no laptop_defconfig on laptops-5.13 at all. Instructions https://github.com/aarch64-laptops/debian-cdimage/#kernel-upgrade says distro_defconfig instead.

[ValkyrieStella]

This is what happens when I try that:

***
*** Can't find default configuration "arch/arm64/configs/distro_defconfig"!
***
make[1]: *** [scripts/kconfig/Makefile:90: distro_defconfig] Error 1
make: *** [Makefile:552: distro_defconfig] Error 2
edgy1@debian:~/linux$ ls arch/arm64/configs/
defconfig  laptops_defconfig
edgy1@debian:~/linux$ 

[ValkyrieStella]

also meant laptops_defconfig not laptop_defconfig

[shawnguo2]

Oops, there is an error in the instructions, the command git checkout -b laptops-5.13 should be git checkout -b laptops-5.13 origin/ laptops-5.13. Fixing it.

There are some important new features for the SC8180X SoC that is used by the Lenovo Flex 5G and the IdeaPad 5G. There are several patches on the mainline support.

The latest version of linux kernel 6.5 supports the Lenovo Flex 5G SoC SC8180X.
