Re: [PATCH 7/7] arc: use the generic remapping allocator for coherent DMA allocations

Hi Christoph, Regular question - do you have any public git repository with all this dma changes? I want to test it for ARC. Pretty sure the [PATCH 2/7] arc: remove the partial DMA_ATTR_NON_CONSISTENT support is fine. Not so sure about [PATCH 7/7] arc: use the generic remapping allocator for

[PATCH] ARC: ARCv2: jump label: implement jump label patching

Implement jump label patching for ARC. Jump labels provide an interface to generate dynamic branches using self-modifying code. This allows us to implement conditional branches where changing branch direction is expensive but branch selection is basically 'free' This implementation uses 32-bit NO

[PATCH 6/7] dma-direct: handle DMA_ATTR_NO_KERNEL_MAPPING in common code

DMA_ATTR_NO_KERNEL_MAPPING is generally implemented by allocating normal cacheable pages or CMA memory, and then returning the page pointer as the opaque handle. Lift that code from the xtensa and generic dma remapping implementations into the generic dma-direct code so that we don't even call arc

[PATCH 7/7] arc: use the generic remapping allocator for coherent DMA allocations

Replace the code that sets up uncached PTEs with the generic vmap based remapping code. It also provides an atomic pool for allocations from non-blocking context, which we not properly supported by the existing arc code. Signed-off-by: Christoph Hellwig --- arch/arc/Kconfig | 2 ++ arch/arc/m

[PATCH 4/7] dma-mapping: add a dma_alloc_need_uncached helper

Check if we need to allocate uncached memory for a device given the allocation flags. Switch over the uncached segment check to this helper to deal with architectures that do not support the dma_cache_sync operation and thus should not returned cacheable memory for DMA_ATTR_NON_CONSISTENT allocati

[PATCH 5/7] dma-direct: handle DMA_ATTR_NON_CONSISTENT in common code

Only call into arch_dma_alloc if we require an uncached mapping, and remove the parisc code manually doing normal cached DMA_ATTR_NON_CONSISTENT allocations. Signed-off-by: Christoph Hellwig --- arch/parisc/kernel/pci-dma.c | 48 ++-- kernel/dma/direct.c

[PATCH 3/7] openrisc: remove the partial DMA_ATTR_NON_CONSISTENT support

The openrisc DMA code supports DMA_ATTR_NON_CONSISTENT allocations, but does not provide a cache_sync operation. This means any user of it will never be able to actually transfer cache ownership and thus cause coherency bugs. Signed-off-by: Christoph Hellwig --- arch/openrisc/kernel/dma.c | 22

The arc DMA code supports DMA_ATTR_NON_CONSISTENT allocations, but does not provide a cache_sync operation. This means any user of it will never be able to actually transfer cache ownership and thus cause coherency bugs. Signed-off-by: Christoph Hellwig --- arch/arc/mm/dma.c | 21 ++

handle "special" dma allocation in common code

Hi all,, this series ensures that the common dma-direct code handles the somewhat special allocation types requested by the DMA_ATTR_NON_CONSISTENT and DMA_ATTR_NO_KERNEL_MAPPING flags directly. To do so it also removes three partial and thus broken implementations of DMA_ATTR_NON_CONSISTENT. La
