I have started a test build for it.

CI failed when building kernel for amd64 with the following message:

 * Building using config /build/amd64-usr/var/tmp/portage/sys-kernel/coreos-modules-5.10.61/files/amd64_defconfig-5.10 and /build/amd64-usr/var/tmp/portage/sys-kernel/coreos-modules-5.10.61/files/commonconfig-5.10
 * ERROR: sys-kernel/coreos-modules-5.10.61::coreos failed (configure phase):
 *   Requested options not enabled in build:
 *     CONFIG_GPIO_SYSFS
 * 
 * Call stack:
 *     ebuild.sh, line  125:  Called src_configure
 *   environment, line 2050:  Called coreos-kernel_src_configure
 *   environment, line  636:  Called die
 * The specific snippet of code:
 *           die "Requested options not enabled in build:
 * ${missing}";

The error comes from eclass/coreos-kernel.eclass. I'm not sure what happened exactly as logs are gone by now, but there seem to be some difference between amd64 and arm64, because arm64 built just fine. Maybe there is some config in arm64_defconfig-5.10 that also needs to be moved to commonconfig-5.10 to satisfy the CONFIG_GPIO_SYFS config on both arm64 and amd64.

@krnowak It seems that both CONFIG_SYSFS and CONFIG_GPIOLIB were missing on amd64. I enabled both in the commonconfig-5.10. Is there a way, I can trigger CI to check whether everything works as expected?

Thanks, I'll restart the CI.

Sorry, not yet. We are working on it, though. :)

CI passed. I think you can mark the PR as "ready for review" now.

@krnowak Done.

Thanks for the PR!
