Hi!
Suspend-to-RAM works on the desktop, but moon key in X no longer

This adds hardware ECC support using the BCH encoder in the NFC IP.
The ECC encoder supports up to 32-bit correction by using 60 error

I think the other functions you've replaced only had a single caller,

As the driver may send multiple wmi commands with identical cmd id,
it is more robust to check seq number for timeout instead.

This enables sPAPR defined feature called Dynamic DMA windows (DDW).
Each Partitionable Endpoint (IOMMU group) has an address range on a PCI bus
where devices are allowed to do DMA. These ranges are called DMA windows.
By default, there is a single DMA window, 1 or 2GB big, mapped at zero

This checks that the TCE table page size is not bigger that the size of

Otherwise the hardware gets unwanted access to physical memory between

This makes use of the it_page_size from the iommu_table struct
as page size can differ.
This replaces missing IOMMU_PAGE_SHIFT macro in commented debug code
as recently introduced IOMMU_PAGE_XXX macros do not include
IOMMU_PAGE_SHIFT.

This replaces multiple calls of kzalloc_node() with a new
iommu_table_alloc() helper. Right now it calls kzalloc_node() but

At the moment the iommu_table struct has a set_bypass() which enables/

Correct. My understanding is whatever can be figured out without DT should
be done that way.

This is a part of moving TCE table allocation into an iommu_ops
callback to support multiple IOMMU groups per one VFIO container.
This enforce window size to be a power of two.

At the moment DMA map/unmap requests are handled irrespective to
the container's state. This allows the user space to pin memory which
it might not be allowed to pin.
This adds checks to MAP/UNMAP that the container is enabled, otherwise
-EPERM is returned.

This clears the TCE table when a container is being closed as this is
a good thing to leave the table clean before passing the ownership
back to the host kernel.

This adds missing locks in iommu_take_ownership()/
iommu_release_ownership().
This marks all pages busy in iommu_table::it_map in order to catch
errors if there is an attempt to use this table while ownership over it
is taken.
This only clears TCE content if there is no page marked busy in it_map
At the moment writing new TCE value to the IOMMU table fails with EBUSY
if there is a valid entry already. However PAPR specification allows
the guest to write new TCE value without clearing it first.

The pnv_pci_ioda_tce_invalidate() helper invalidates TCE cache. It is
supposed to be called on IODA1/2 and not called on p5ioc2. It receives
start and end host addresses of TCE table. This approach makes it possible
to get pnv_pci_ioda_tce_invalidate() unintentionally called on p5ioc2.
