* dma: Let dma_buf_write() take MemTxAttrs argumentPhilippe Mathieu-Daudé2021-12-311-3/+2Star

* dma: Have dma_buf_read() / dma_buf_write() take a void pointerPhilippe Mathieu-Daudé2021-12-301-2/+2
| | | | | | | | | | | | DMA operations are run on any kind of buffer, not arrays of uint8_t. Convert dma_buf_read/dma_buf_write functions to take a void pointer argument and save us pointless casts to uint8_t *. Remove this pointless casts in the megasas device model.

* dma: Introduce dma_aligned_pow2_mask()Eric Auger2021-03-121-0/+26
| | | | | | | | | | | | | | | | | | | | | Currently get_naturally_aligned_size() is used by the intel iommu to compute the maximum invalidation range based on @size which is a power of 2 while being aligned with the @start address and less than the maximum range defined by @gaw. This helper is also useful for other iommu devices (virtio-iommu, SMMUv3) to make sure IOMMU UNMAP notifiers only are called with power of 2 range sizes. Let's move this latter into dma-helpers.c and rename it into dma_aligned_pow2_mask(). Also rewrite the helper so that it accomodates UINT64_MAX values for the size mask and max mask. It now returns a mask instead of a size. Change the caller.
