...meaning 'device DMA frame number' i.e. a frame number mapped in the IOMMU (rather than the MMU) and hence used for DMA address translation.This patch is a largely cosmetic change that substitutes the terms 'gfn' and 'gaddr' for 'dfn' and 'daddr' in all the places where the frame number or address relate to a device rather than the CPU. The parts that are not purely cosmetic are: - the introduction of a type-safe declaration of dfn_t and definition of INVALID_DFN to make the substitution of gfn_x(INVALID_GFN) mechanical. - the introduction of __dfn_to_daddr and __daddr_to_dfn (and type-safe variants without the leading __) with some use of the former. Subsequent patches will convert code to make use of type-safe DFNs.
