Can you please take a look at this patch. Without it the functionality

A previous change introduced the usage of DDW as a bigger indirect DMA
mapping when the DDW available size does not map the whole partition.

So far it's assumed possible to map the guest RAM 1:1 to the bus, which
works with a small number of devices. SRIOV changes it as the user can

These normally go right before "signed-off-by".
Some functions assume IOMMU page size can only be 4K (pageshift == 12).
Update them to accept any page size passed, so we can use

Having System pagesize < IOMMU pagesize may cause a page owned by another
process/VM to be written by a buggy driver / device.
As it's intended to use DDW for indirect mapping, it's

Update remove_dma_window() so it can be used to remove DDW with a given

Out of context this seems useless. How about?

Add a new helper _iommu_table_setparms(), and use it in

Having a function to check if the iommu table has any allocation helps
deciding if a tbl can be reset for using a new DMA window.
It should be enough to replace all instances of

Currently both iommu_alloc_coherent() and iommu_free_coherent() align the
desired allocation size to PAGE_SIZE, and gets system pages and IOMMU
mappings (TCEs) for that value.

There are two functions creating direct_window_list entries in a
similar way, so create a ddw_list_new_entry() to avoid duplicity and
simplify those functions.
