I'd rather keep the host1x driver where it is for now. There aren't any users external to DRM yet, so I don't see a reason for moving it out. Instead we can use DRM as a playground, see what we really need and once external users start to appear we can think about moving the host1x code somewhere else. > This modification introduces a regression: Because there is no > general framework for attaching separate devices into the > same address space, this patch removes the ability to use IOMMU > in tegradrm. So the IOMMU support was up for discussion anyway and I wasn't going to submit it for inclusion anytime soon either. No harm done. Aside from ripping out the existing host1x code, the remainder of this patch is mostly renaming from host1x_client to tegra_drm_client, so I won't comment on it.
