Here's an attempt go back to a saner default. I tested this on both a RPi4 and QEMU. --- Changes since v4: - Fix of_dma_get_max_cpu_address() so it returns the last addressable addres, not the limit Changes since v3: - Drop patch adding define in dma-mapping - Address small review changes - Update Ard's patch - Add new patch removing examples from mmzone.h Changes since v2: - Introduce Ard's patch - Improve OF dma-ranges parsing function - Add unit test for OF function - Address small changes - Move crashkernel reservation later in boot process Changes since v1: - Parse dma-ranges instead of using machine compatible string Ard Biesheuvel (1): arm64: mm: Set ZONE_DMA size based on early IORT scan Nicolas Saenz Julienne (6): arm64: mm: Move reserve_crashkernel() into mem_init() arm64: mm: Move zone_dma_bits initialization into zone_sizes_init() of/address: Introduce of_dma_get_max_cpu_address() of: unittest: Add test for of_dma_get_max_cpu_address() arm64: mm: Set ZONE_DMA size based on devicetree's dma-ranges mm: Remove examples from enum zone_type comment arch/arm64/mm/init.c | 16 ++++++------ drivers/acpi/arm64/iort.c | 52 +++++++++++++++++++++++++++++++++++++++ drivers/of/address.c | 42 +++++++++++++++++++++++++++++++ drivers/of/unittest.c | 18 ++++++++++++++ include/linux/acpi_iort.h | 4 +++ include/linux/mmzone.h | 20 --------------- include/linux/of.h | 7 ++++++ 7 files changed, 130 insertions(+), 29 deletions(-) -- 2.29.0 _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
