This patch sets add a FF-A [1] mediator modeled after the TEE mediator
already present in Xen. The FF-A mediator implements the subset of the FF-A

Hi all,
Just a quick note to have another look at the spreadsheet before the

Hello,
I used to send out a patchset on 64-bit buffer and people thought it was
the same as Restricted DMA. However, the 64-bit buffer is still not supported.
https://lore.kernel.org/all/20210203233709.19819-1-dongli.zh...@oracle.com/
This RFC is to introduce the extra swiotlb buffer with SWIOTL
Currently, the virtio driver is not able to use 4+ GB memory when the
swiotlb is enforced, e.g., when amd sev is involved.
Fortunately, the SWIOTLB_ANY flag has been introduced since
commit 8ba2ed1be90f ("swiotlb: add a SWIOTLB_ANY flag to lift the low
memory restriction") to allocate swiotlb buff
Since the type of swiotlb slot index is a signed integer, the
"((idx) << IO_TLB_SHIFT)" will returns incorrect value. As a result, the
slot_addr() returns a value which is smaller than the expected one.
E.g., the 'tlb_addr' generated in swiotlb_tbl_map_single() may return a
value smaller than the
While for most of times the swiotlb-xen relies on the generic swiotlb api
to initialize and use swiotlb, this patch is to support highmem swiotlb
for swiotlb-xen specific code.
E.g., the xen_swiotlb_fixup() may request the hypervisor to provide
64-bit memory pages as swiotlb buffer.
Cc: Konrad Wi
This patch is to implement the extra 'io_tlb_high_mem'. In the future, the
device drivers may choose to use either 'io_tlb_default_mem' or
'io_tlb_high_mem' as dev->dma_io_tlb_mem.
The highmem buffer is regarded as active if
(high_nslabs && io_tlb_high_mem.nslabs) returns true.

The interface re-configures dev->dma_io_tlb_mem conditionally, if the
