To address the case where physically contiguous memory MAY NOT be a mandatory requirement for framebuffer for the application calling exynos_drm_gem_dumb_create, the patch adds a feature to get non physically contiguous memory for framebuffer, if physically contiguous memory allocation fails and if IOMMU is
supported.
