Depending on the kernel configuration, early ARM architecture setup code may have attached the GPU to a DMA/IOMMU mapping that transparently uses the IOMMU to back the DMA API. Tegra requires special handling for IOMMU backed buffers (a special bit in the GPU's MMU page tables indicates the memory path to take: via the SMMU or directly to the memory controller). Transparently backing DMA memory with an IOMMU prevents Nouveau from properly handling such memory accesses and causes memory access faults. As a side-note: buffers other than those allocated in instance memory don't need to be physically contiguous from the GPU's perspective since the GPU can map them into contiguous buffers using its own MMU. Mapping these buffers through the IOMMU is unnecessary and will even lead to performance degradation because of the additional translation. One exception to this are compressible buffers which need large pages. In order to enable these large pages, multiple small pages will have to be combined into one large (I/O virtually contiguous) mapping via the IOMMU. However, that is a topic outside the scope of this fix and isn't currently supported. An implementation will want to explicitly create these large pages in the Nouveau driver, so detaching from a DMA/IOMMU mapping would still be required. Signed-off-by:

In the quest to remove all stack VLA usage from the kernel[1], this allocates the working buffers before starting the writing so it won't abort in the middle.

With instantaneous high precision vblank timestamping that updates at leading edge of vblank, the emulated "hw vblank counter" from vblank timestamping, which increments at leading edge of vblank, and reliable page flip execution and completion at leading edge of vblank, we should meet the requirements for fast/ immediate vblank irq disable/enable. This is only allowed on nv50+ gpu's, ie. the ones with atomic modesetting. One requirement for immediate vblank disable is that high precision vblank timestamping works reliably all the time on all connectors. This is not the case on all pre-nv50 parts for analog VGA outputs, where we currently don't always have support for scanout position queries and therefore fall back to vblank interrupt timestamping. The implementation in nv04_head_state() does not return valid values for vblanks, vtotal, hblanks, htotal for VGA outputs on all cards, but those are needed for scanout position queries. Testing on Linux-4.12-rc5 + drm-next on a GeForce 9500 GT (NV G96) with timing measurement equipment indicates this works fine, so allow immediate vblank disable for power saving. For debugging in case of unexpected trouble, booting with kernel cmdline option drm.vblankoffdelay=0 (or echo 0 > /sys/module/drm/parameters/vblankoffdelay) would keep vblank irqs permanently on to approximate old behavior.

Commit 894a677f ("drm/cma-helper: Use the generic fbdev emulation") broke almost all drivers that use the CMA helper. The reason is that drm_client_new() requires that the DRM device has been registered, but the drivers register fbdev before registering DRM. Remove the requirement that DRM should be registered when creating a new client.
