--- Comment #3 from Harry Wentland harry.wentland@amd.com --- Created attachment 138813 --> https://bugs.freedesktop.org/attachment.cgi?id=138813&action=edit [PATCH] drm/amd/display: Support LVDS panels
Can you see if this fixes things or creates different problems at boot? Looks like we never really supported LVDS with DC but a whole bunch of code is there.
If it crashes and burns let me know your dmesg again. I'm hoping everything is in place but it's quite likely that we're missing some more crucial pieces.

--- Comment #5 from Shawn Starr shawn.starr@rogers.com --- For reference compiling amdgpu.ko with custom patch on a Fedora kernel:
1) rpm -ivh kernel-4.17.0-0.rc0.git7.2.fc29.src.rpm
2) Copy custom patch into rpmbuild/SOURCES
3) Modify kernel.spec to add patch into the listing
4) cd ~/rpmbuild/SPECS; rpmbuild -bp kernel.spec
5) cd ~/rpmbuild/BUILD/kernel-4.16.fc27/linux-4.17.0-0.rc0.git7.2.fc29.x86_64
6) vi Makefile --> add the proper matching kernel version '-0.rc0.git7.2.fc29.x86_64' to EXTRAVERSION.
7) cp /boot/config-4.17.0-0.rc0.git7.2.fc29.x86_64 ~/rpmbuild/BUILD/kernel/4.16.fc17/linux-4.17.0-0.rc0.git7.2.fc29.x86_64/.config
8) cp /lib/modules/4.17.0-0.rc0.git7.2.fc29.x86_64/build/Module.symvers ~/rpmbuild/BUILD/kernel/4.16.fc17/linux-4.17.0-0.rc0.git7.2.fc29.x86_64/
9) cd ~/rpmbuild/BUILD/kernel/4.16.fc17/linux-4.17.0-0.rc0.git7.2.fc29.x86_64/certs && cp ~/rpmbuild/SOURCES/x509.genkey .
10) cd .. && make certs
11) make modules_prepare
12) make M= drivers/gpu/drm/amd/amdgpu modules
13) ./scripts/sign-file sha256 certs/signing_key.pem certs/signing_key.x509 drivers/gpu/drm/amd/amdgpu/amdgpu.ko
14) compress kernel modules with xz
15) Replace/move original in /lib/modules/4.17.0-0.rc0.git7.2.fc29.x86_64/drives/dpu/drm/amd/amdgpu/ of way
16) depmod -a
17) Remove old initramfs and rebuild with dracut
