...t <acourbot at nvidia.com> --- Vince, with this you won't have to export new functions for PM. I ended up writing it myself because I hit the same issue (nv_device() would now need to be exported on Ben's master branch). Be careful that when compiling against a kernel, CONFIG_NOUVEAU_PLATFORM_DRIVER now *must* be equal to 'y'. It is 'm' currently, so you will need to change it from tristate to bool in the kernel's Kconfig. For this reason it might be good to get this patch into -next quickly. drm/Kbuild | 3 +-- drm/Kconfig | 2 +- drm/nouveau_drm...

Hello, There is a trouble on ARM with DMA allocations made by device drivers, the trouble is that DMA allocations are getting implicitly backed with IOMMU mapping by the driver core if IOMMU presents in a system and IOMMU could handle device. This is an undesired behaviour for drivers that manage IOMMU by themselves, like NVIDIA Tegra GPU driver. On arm32 the implicit backing happens if

These 4 patches fix two issues that existed on Tegra regarding DMA: 1) The bit indicating whether to use an IOMMU or not was hardcoded ; make this a platform property and use it in instmem 2) The DMA mask was not set for platform devices. Fix this by converting more pci_dma* to the DMA API, and use that more generic code to set the DMA mask properly for all platforms. Tested on both x86
