microblaze: Remove noMMU code

2020-11-26T15:39:35+00:00

This configuration is obsolete and likely none is really using it. That's why remove it to simplify code. Note about CONFIG_MMU in hw_exception_handler.S is left intentionally for better comment understanding.

dma-mapping: merge into

2020-10-06T05:07:06+00:00

Move more nitty gritty DMA implementation details into the common internal header. Signed-off-by: Christoph Hellwig

dma-direct: make uncached_kernel_address more general

2020-03-16T09:48:09+00:00

Rename the symbol to arch_dma_set_uncached, and pass a size to it as well as allow an error return. That will allow reusing this hook for in-place pagetable remapping. As the in-place remap doesn't always require an explicit cache flush, also detangle ARCH_HAS_DMA_PREP_COHERENT from ARCH_HAS_DMA_SET_UNCACHED.

dma-direct: remove the cached_kernel_address hook

2020-03-16T09:48:02+00:00

dma-direct now finds the kernel address for coherent allocations based on the dma address, so the cached_kernel_address hooks is unused and can be removed entirely. Signed-off-by: Christoph Hellwig Reviewed-by: Robin Murphy

microblaze: use the generic dma coherent remap allocator

2019-08-30T09:47:16+00:00

This switches to using common code for the DMA allocations, including potential use of the CMA allocator if configured. Switching to the generic code enables DMA allocations from atomic context, which is required by the DMA API documentation, and also adds various other minor features drivers start relying upon. It also makes sure we have on tested code base for all architectures that require uncached pte bits for coherent DMA allocations. Signed-off-by: Christoph Hellwig Signed-off-by: Michal Simek

microblaze/nommu: use the generic uncached segment support

Stop providing our own arch alloc/free hooks for nommu platforms and just expose the segment offset and use the generic dma-direct allocator. Signed-off-by: Christoph Hellwig Signed-off-by: Michal Simek

dma-mapping: zero memory returned from dma_alloc_*

2018-12-20T07:13:52+00:00

If we want to map memory from the DMA allocator to userspace it must be zeroed at allocation time to prevent stale data leaks. We already do this on most common architectures, but some architectures don't do this yet, fix them up, either by passing GFP_ZERO when we use the normal page allocator or doing a manual memset otherwise.
