Whoops, sorry for the failed, much appreciated for your works. Besides, I thought maybe I can find a Peach Pit Chromebook in my side, I remember that some of our guys have brought one, but previously I thought that mainline kernel wouldn't run on Peach Pit directly. Maybe you can email me the method the run mainline kernel on Peach Pit, so I can debug the analogix_dp driver at the same time, that would be great. > 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.
