This time dma_map_ops callbacks are converted to physical addresses, what in turn results also in some simplification of architecture specific code (Leon Romanovsky and Jason Gunthorpe) - Clarify that dma_map_benchmark is not a kernel self-test, but standalone tool (Qinxin Xia) * tag 'dma-mapping-6.19-2025-12-05' of git://git.kernel.org/pub/scm/linux/kernel/git/mszyprowski/linux: dma-mapping: remove unused map_page callback xen: swiotlb: Convert mapping routine to rely on physical address x86: Use physical address for DMA mapping sparc: Use physical address DMA mapping powerpc: Convert to physical address DMA mapping parisc: Convert DMA map_page to map_phys interface MIPS/jazzdma: Provide physical address directly alpha: Convert mapping routine to rely on physical address dma-mapping: remove unused mapping resource callbacks xen: swiotlb: Switch to physical address mapping callbacks ARM: dma-mapping: Switch to physical address mapping callbacks ARM: dma-mapping: Reduce struct page exposure in arch_sync_dma*() dma-mapping: convert dummy ops to physical address mapping dma-mapping: prepare dma_map_ops to conversion to physical address tools/dma: move dma_map_benchmark from selftests to tools/dma 2025-10-29T08:41:40+00:00 Qinxin Xia xiaqinxin@huawei.com 2025-10-28T12:09:00+00:00 urn:sha1:f74ee32963f1b74865fe679e2475450434fea51c dma_map_benchmark is a standalone developer tool rather than an automated selftest. It has no pass/fail criteria, expects manual invocation, and is built as a normal userspace binary. Move it to tools/dma/ and add a minimal Makefile.
