Thanks Ilia for the v2 review! Here is the v3 of this IOMMU support for GK20A series. Changes since v2: - Cleaner changes for ltc - Fixed typos in gk20a instmem IOMMU comments Changes since v1: - Add missing else condition in ltc - Remove extra flags that slipped into nouveau_display.c and nv84_fence.c. Original cover letter: Patches 1-3 make the presence of a RAM device optional, and remove

Changes since v3: - Use a single dma_attr for all DMA-API allocations in instmem instead of one per allocation - Use device.info.ram_size instead of pfb->ram to check whether VRAM is present outside of nvkm Changes since v2: - Cleaner changes for ltc - Fixed typos in gk20a instmem IOMMU comments Changes since v1: - Add missing else condition in ltc - Remove extra flags that slipped into
