Any comments or additional testing? It would be really great to get this off the table. On Tue, Jun 14, 2022 at 11:20:37AM +0200, Christoph Hellwig wrote:
Hi all, arm is the last platform not using the dma-direct code for directly mapped DMA. With the dmaboune removal from Arnd we can easily switch arm to always use dma-direct now (it already does for LPAE configs and nommu). I'd love to merge this series through the dma-mapping tree as it gives us the opportunity for additional core dma-mapping improvements. Changes since v2: - rebased to Linux 5.19-rc2 Changes since v1: - remove another unused function - improve a few commit logs - add three more patches from Robin Diffstat: arch/arm/common/dmabounce.c | 582 ----------------- arch/arm/include/asm/dma-mapping.h | 128 --- b/arch/arm/Kconfig | 5 b/arch/arm/common/Kconfig | 6 b/arch/arm/common/Makefile | 1 b/arch/arm/common/sa1111.c | 64 - b/arch/arm/include/asm/device.h | 3 b/arch/arm/include/asm/dma-direct.h | 49 - b/arch/arm/include/asm/memory.h | 2 b/arch/arm/mach-footbridge/Kconfig | 1 b/arch/arm/mach-footbridge/common.c | 19 b/arch/arm/mach-footbridge/include/mach/dma-direct.h | 8 b/arch/arm/mach-footbridge/include/mach/memory.h | 4 b/arch/arm/mach-highbank/highbank.c | 2 b/arch/arm/mach-mvebu/coherency.c | 2 b/arch/arm/mm/dma-mapping.c | 649 ++----------------- b/drivers/usb/core/hcd.c | 17 b/drivers/usb/host/ohci-sa1111.c | 25 18 files changed, 137 insertions(+), 1430 deletions(-) _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
