To Reproduce

Build on ppc64le with 64k pages and load nvidia-drm.ko

Bug Incidence

Always

More Info

This is on ppc64le with 64KiB pages

Please note that the Makefiles for ppc64le are broken in various ways, so building nvidia-drm.ko required some changes. I can submit patches to fix them if there is community/maintainer interest.

Thank you for your report. Unfortunately, we don't currently plan to support ppc64le with the open-gpu-kernel-modules. Closing; sorry.
