Subject: [PATCH v5 0/7] arm64: Default to 32-bit wide ZONE_DMA
Date: Thu, 29 Oct 2020 18:25:43 +0100 [thread overview]
Message-ID: <20201029172550.3523-1-nsaenzjulienne@suse.de> (raw)
Using two distinct DMA zones turned out to be problematic. 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
