Hi all, The main goal is to have the SLES12 SP3 kernel version 4.4.140-94.42.1 the fix it needed for Kabylake graphics issue and also enable the dp aux character device CONFIG_DRM_DP_AUX_CHARDEV=y. I like to inquiry if there's a way or how to proceed with this correctly. My question is I have a Intel Kabylake graphics and the Linux OS I installed in my system is SLES12 SP3 with kernel version 4.4.140-94.42.1. To support and fix the Kabylake graphics issue under this kernel I also installed/updated the drm-kmp-default which is a backported drm kernel modules. From here, I also wanted to enable the CONFIG_DRM_DP_AUX_CHARDEV=y. It seems to me the drm-kmp-default file (*.ko) are build by default and the CONFIG_DRM_DP_AUX_CHARDEV=n is disable. Is there a possible way to enable this? Or how to approach with this problem? If I rebuild the drm-kmp-default into my kernel version 4.4.140-94.42.1 source, I got a lot of errors because I assume the drm-kmp-default is under a higher drm version which is 4.9. Please advise and have comments. Kernel version list:SUSE/SLES/Kernel versions - MicroFocusInternationalWiki drm-kmp-default site:https://software.opensuse.org/package/drm-kmp-default Thanks,John
