[v1] sun4m: implement memory region IOMMU translation and DMA API

[Qemu-devel] [PATCHv2 0/4] sun4m: implement memory region IOMMU translation and DMA API

Posted by Mark Cave-Ayland 8 years ago

The original sun4m IOMMU/DMA code dates from before the introduction of the QEMU
memory region API (in particular IOMMU memory regions) and the DMA API.

This patchset removes these sun4m-specific implementations and replaces them with
the more up-to-date QEMU APIs instead.

v2:
- Rebase onto v4 sparc32_dma tidy-up patchset
- Change TYPE_SUN4M_IOMMU macro from "iommu" to "sun4m-iommu" as suggested by Philippe


Mark Cave-Ayland (4):
  sun4m: implement IOMMU translation using IOMMU memory region
  sparc32_dma: switch over to using IOMMU memory region and DMA API
  sun4m_iommu: remove legacy sparc_iommu_memory_rw() function
  sun4m: change TYPE_SUN4M_IOMMU macro from "iommu" to "sun4m-iommu"
