Until now, the MSI architecture-specific functions could be overloaded
using a fairly complex set of #define and compile-time

the 'weak' mechanism. This commit
Now that we have weak versions for each of the PCI MSI architecture
functions, we can actually build the MSI support for all platforms,
regardless of whether they provide or not architecture-specific
versions of those functions. For this reason, the ARCH_SUPPORTS_MSI

support results in capturing more data within limited space.

The current VFIO-on-POWER implementation supports only user mode
driven mapping, i.e. QEMU is sending requests to map/unmap pages.
However this approach is really slow, so we want to move that to KVM.
Since H_PUT_TCE can be extremely performance sensitive (especially with
network adapters where eac
VFIO is designed to be used via ioctls on file descriptors
returned by VFIO.
However in some situations support for an external user is required.
The first user is KVM on PPC64 (SPAPR TCE protocol) which is going to
use the existing VFIO groups for exclusive access in real/virtual mode
on a host t
The existing TCE machine calls (tce_build and tce_free) only support
virtual mode as they call __raw_writeq for TCE invalidation what
fails in real mode.
This introduces tce_build_rm and tce_free_rm real mode versions
which do mostly the same but use "Store Doubleword Caching Inhibited
Indexed" in
This adds real mode handlers for the H_PUT_TCE_INDIRECT and
H_STUFF_TCE hypercalls for user space emulated devices such as IBMVIO
devices or emulated PCI. These calls allow adding multiple entries
(up to 512) into the TCE table in one call which saves time on
transition to/from real mode.
This ad
It does not make much sense to have KVM in book3s-64bit and
not to have IOMMU bits for PCI pass through support as it costs little
and allows VFIO to function on book3s-kvm.
Having IOMMU_API enabled will make it unnecessary to have a lot of
IOMMU_API enabled, those files only accelerate user space
The TCE tables handling may differ for real and virtual modes so
additional ppc_md.tce_build_rm/ppc_md.tce_free_rm/ppc_md.tce_flush_rm
handlers were introduced earlier.
So this adds the following:
1. support for the new ppc_md calls;
2. ability to iommu_tce_build to process mupltiple entries per

This adds special support for huge pages (16MB) in real mode.
The reference counting cannot be easily done for such pages in real
mode (when MMU is off) so we added a hash table of huge pages.
It is populated in virtual mode and get_page is called just once

This allows the host kernel to handle H_PUT_TCE, H_PUT_TCE_INDIRECT
