[PATCH 00/14] ARM: remove unused davinci board & drivers
by Arnd Bergmann 14 Nov '22

14 Nov '22

From: Arnd Bergmann <arnd(a)arndb.de> As part of removing all board files that were previously marked as unused, I looked through the davinci platform and recursively removed everything that has now become unused. In particular, this is for all dm3xx support, in addition to the dm64xx support removed previously. The remaining support is now for da8xx using devicetree only, which means a lot of the da8xx specific device support can also go away. As with the previous series, I can keep patches together in the soc tree, or subsystem maintainers can pick them up individually through their subsystems, whichever they prefer.

It turns out there was additional problem with dma_alloc_noncontiguous that led to ENOMEM much more frequently than in the past. This required following: - your rework in 5.16 to sound/core/memalloc.c for x86 DMA SG - IOMMU/DMAR enabled for the device - CONFIG_DMA_REMAP=n (default 'n' on most/all x86 systems before 5.18) ... with above combination, iommu_dma_ops in drivers/iommu/dma-iommu.c were not defined for noncontiguous alloc/free, so the dma_alloc_noncontiguous() in the end went back to plain dma_common_alloc_pages() (single contiguous alloc), which would fail very easily when system was in low-mem condition. In 5.18, this patch was added commit f5ff79fddf0efecca538046b5cc20fb3ded2ec4f Author: Christoph Hellwig <hch(a)lst.de> Date: Sat Feb 26 16:40:21 2022 +0100 dma-mapping: remove CONFIG_DMA_REMAP ... and this basicly fixes the issue again, even when IOMMU is enabled.
