View Full Version : SLED 12 SP3 DRM inquiry to Backported drm kernel modules.

02-Aug-2018, 12:57
Hi everyone,

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 built 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.

Hi John,

Welcome to the SUSE forums. As a new member, you should read the SUSE

The Knowledge Partners monitor all the forums so if you have a question
just choose what you think might be an appropriate forum. Should it be
more appropriate to ask your question in a different forum, we will let
you know.

Since this question is about SUSE Linux Enterprise *Server* the other
forum you posted to is the correct one:

I am closing this thread and ask that all replies be made to the post
in the SLES Install-Boot forum using the above link.
