[PATCH v6 0/3] PCIe Host request to reserve IOVA
This patch set will reserve IOVA addresses for DMA memory holes. The IPROC host controller allows only a few ranges of physical address as inbound PCI addresses which are listed through dma-ranges DT property. Added dma_ranges list field of PCI host bridge structure to hold these allowed inbound address ranges in sorted order. Process this list and reserve IOVA addresses that are not present in its resource entries (ie DMA memory holes) to prevent allocating IOVA addresses that cannot be allocated as inbound addresses. This patch set is based on Linux-5.1-rc3. Changes from v5: - Addressed Robin Murphy, Lorenzo review comments. - Error handling in dma ranges list processing. - Used commit messages given by Lorenzo to all patches. Changes from v4: - Addressed Bjorn, Robin Murphy and Auger Eric review comments. - Commit message modification. - Change DMA_BIT_MASK to "~(dma_addr_t)0". Changes from v3: - Addressed Robin Murphy review comments. - pcie-iproc: parse dma-ranges and make sorted resource list. - dma-iommu: process list and reserve gaps between entries Changes from v2: - Patch set rebased to Linux-5.0-rc2 Changes from v1: - Addressed Oza review comments.
