d7eafe655b741dfc241d5b920f6d2cea45b568d9 - dma-mapping: Separate DMA sync issuing and completion waiting

Sat, 28 Feb 2026 23:13:16 +0100

dma-mapping: Separate DMA sync issuing and completion waitingCurrently, arch_sync_dma_for_cpu and arch_sync_dma_for_devicealways wait for the completion of each DMA buffer. That is,issuing the DMA sync and waiting for completion is done in asingle API call.For scatter-gather lists with multiple entries, this meansissuing and waiting is repeated for each entry, which can hurtperformance. Architectures like ARM64 may be able to issue allDMA sync operations for all entries first and then wait forcompletion together.To address this, arch_sync_dma_for_* now batches DMA operationsand performs a flush afterward. On ARM64, the flush is implementedwith a dsb instruction in arch_sync_dma_flush(). On otherarchitectures, arch_sync_dma_flush() is currently a nop.Cc: Leon Romanovsky Cc: Catalin Marinas Cc: Will Deacon Cc: Marek Szyprowski Cc: Robin Murphy Cc: Ada Couprie Diaz Cc: Ard Biesheuvel Cc: Marc Zyngier Cc: Anshuman Khandual Cc: Ryan Roberts Cc: Suren Baghdasaryan Cc: Joerg Roedel Cc: Stefano Stabellini Cc: Oleksandr Tyshchenko Cc: Tangquan Zheng Reviewed-by: Juergen Gross # drivers/xen/swiotlb-xen.cTested-by: Xueyuan Chen Signed-off-by: Barry Song Reviewed-by: Leon Romanovsky Signed-off-by: Marek Szyprowski Link: https://lore.kernel.org/r/20260228221316.59934-1-21cnbao@gmail.com List of files: /linux/kernel/dma/Kconfig
