I wrote a little blog post explaining how to run mainline on these boards: http://blogs.s-osg.org/install-linux-mainline-kernel-distro-exynos-chromebooks/ That explains the simplest setup though so if you need a different one (i.e: chain loading a non verified u-boot) or if you have any questions, feel free to contact me in private and I can help you with the setup. >> Also, there is Kconfig recursive dependency that you may want to fix: >> >> $ make exynos_defconfig >> drivers/video/fbdev/Kconfig:5:error: recursive dependency detected! >> drivers/video/fbdev/Kconfig:5: symbol FB is selected by DRM_KMS_FB_HELPER >> drivers/gpu/drm/Kconfig:34: symbol DRM_KMS_FB_HELPER depends on DRM_KMS_HELPER >> drivers/gpu/drm/Kconfig:28: symbol DRM_KMS_HELPER is selected by DRM_ANALOGIX_DP >> drivers/gpu/drm/bridge/analogix/Kconfig:1: symbol DRM_ANALOGIX_DP is selected by DRM_EXYNOS_DP >> drivers/gpu/drm/exynos/Kconfig:57: symbol DRM_EXYNOS_DP depends on DRM_EXYNOS_FIMD >> drivers/gpu/drm/exynos/Kconfig:19: symbol DRM_EXYNOS_FIMD depends on FB_S3C >> drivers/video/fbdev/Kconfig:2023: symbol FB_S3C depends on FB >> > > Yeah, recursive dependency detected, guess I should remove the > "DRM_KMS_HELPER" from bridge analogix_dp Kconfig file, thanks > for your remind. > > --- a/drivers/gpu/drm/bridge/analogix/Kconfig > +++ b/drivers/gpu/drm/bridge/analogix/Kconfig > @@ -1,4 +1,3 @@ > config DRM_ANALOGIX_DP > tristate > depends on DRM > - select DRM_KMS_HELPER > > That fixes the recursive dependency issue indeed.
