VRAM MM and GEM VRAM are only used with each other. This patch set moves VRAM MM into GEM VRAM source files and cleans up the helper's public interface. Thomas Zimmermann (4): drm/vram: Move VRAM memory manager to GEM VRAM implementation drm/vram: Have VRAM MM call GEM VRAM functions directly drm/vram: Unexport internal functions of VRAM MM drm/vram: Unconditonally set BO call-back

VRAM MM and GEM VRAM are only used with each other. This patch set moves VRAM MM into GEM VRAM source files and cleans up the helper's public interface. Version 2 of the patch set doesn't contain functional changes. I'm reposting due to the rebasing onto the debugfs patches. v2: * updated for debugfs support * fixed typos in comments Thomas Zimmermann (4): drm/vram: Move VRAM

@Michal: Thanks for your reply! Indeed I have found a package in the AUR (libvirt-zfs) and only had to change to the current version and add zfs-utils as dependency in the PKGBUILD. Now I don't get the previous error anymore but I still cannot setup a VM because I constantly get errors due to wrong permissions. I have tried to change the permissions in: - /etc/libvirt/qemu.conf -
