From: Greg Kurz <groug@kaod.org>
The following capabilities are VM specific:
- KVM_CAP_PPC_SMT_POSSIBLE
- KVM_CAP_PPC_HTAB_FD
- KVM_CAP_PPC_ALLOC_HTAB
If both KVM HV and KVM PR are present, checking them always return
the HV value, even if we explicitely requested to use PR.
This has no visible effect for KVM_CAP_PPC_ALLOC_HTAB, because we also
try the KVM_PPC_ALLOCATE_HTAB ioctl which is only suppored by HV. As
a consequence, the spapr code doesn't even check KVM_CAP_PPC_HTAB_FD.
However, this will cause kvmppc_hint_smt_possible(), introduced by
commit fa98fbfcdfcb9, to report several VSMT modes (eg, Available
VSMT modes: 8 4 2 1) whereas PR only support mode 1.
This patch fixes all three anyway to use kvm_vm_check_extension(). It
is okay since the VM is already created at the time kvm_arch_init() or
kvmppc_reset_htab() is called.

These registers are present in 440 SoCs (and maybe in others too) and
U-Boot accesses them when printing register info. We don't emulate
these but add them to avoid crashing when they are read or written.

This completely reworks the handling of the control register
according to my understanding of the HW and the spec.
It should (hopefully ... still testing) fix a number of issues
most notably cases of MacOS hanging.
Also update dbdma_unassigned_rw() and dbdma_unassigned_flush() to
have the expected behaviour now that flush is handled slightly
differently.

The timing register exists on all variants of MacIO IDE, we just
store and return its value.
The interrupts register only exists on KeyLargo but it doesn't
hurt to have it. The lack of this register causes MacOS X to
hangs under some circumstances.
Both are 32-bit only. The HW might support smaller access sizes
but no known OS uses them.
Because the core IDE subsystem doesn't provide us with a way
to query the main (level) interrupt state, nor do we have a way
to know that DBDMA issued a (edge) interrupt, we reflect both
through a private pair of qirq's in order to maintain the
register state.

From: Greg Kurz <groug@kaod.org>
When kvmppc_get_htab_fd() fails, its return value is propagated up to
qemu_savevm_state_iterate() or to qemu_savevm_state_complete_precopy().
All savevm handlers expect to receive a negative errno on error.
Let's patch kvmppc_get_htab_fd() accordingly.
While here, let's change htab_load() in the spapr code to also
propagate the error, since it doesn't make sense to abort() if
we couldn't get the htab fd from KVM.

From: Greg Kurz <groug@kaod.org>
The use of KVM_PPC_GET_HTAB_FD is open-coded in kvmppc_read_hptes()
and kvmppc_write_hpte().
This patch modifies kvmppc_get_htab_fd() so that it can be used
everywhere we need to access the in-kernel htab:
- add an index argument
=> only kvmppc_read_hptes() passes an actual index, all other users
pass 0
- add an errp argument to propagate error messages to the caller.
=> spapr migration code prints the error
=> hpte helpers pass &error_abort to keep the current behavior
of hw_error()
While here, this also fixes a bug in kvmppc_write_hpte() so that it
opens the htab fd for writing instead of reading as it currently does.
This never broke anything because we currently never call this code,
as explained in the changelog of commit c1385933804bb:
"This support updating htab managed by the hypervisor. Currently
we don't have any user for this feature. This actually bring the
store_hpte interface in-line with the load_hpte one. We may want
to use this when we want to emulate henter hcall in qemu for HV
kvm."
The above is still true today.

Although none of the existing macro call-sites were broken,
it's always better to write macros that properly parenthesize
arguments that can be complex expressions, so that the intended
order of operations is not broken.

From: Greg Kurz <groug@kaod.org>
PHBs can be created with an index property, in which case the machine
code automatically sets all the MMIO windows at addresses derived from
the index. Alternatively, they can be manually created without index,
but the user has to provide addresses for all MMIO windows.
The non-index way happens to be more trouble than it's worth: it's
difficult to use, keeps requiring (potentially incompatible) changes
when some new parameter needs adding, and is awkward to check for
collisions. It currently even has a bug that prevents to use two
non-index PHBs because their child DRCs are all derived from the
same index == -1 value, and, thus, collide.
This patch hence makes the index property mandatory. As a consequence,
the PHB's memory regions and BUID are now always configured according
to the index, and it is no longer possible to set them from the command
line.
This DOES BREAK backwards compat, but we don't think the non-index
PHB feature was used in practice (at least libvirt doesn't) and the
simplification is worth it.

From: Greg Kurz <groug@kaod.org>
When running with KVM PR, if a new HPT is allocated we need to inform
KVM about the HPT address and size. This is currently done by hacking
the value of SDR1 and pushing it to KVM in several places.
Also, migration breaks the guest since it is very unlikely the HPT has
the same address in source and destination, but we push the incoming
value of SDR1 to KVM anyway.
This patch introduces a new virtual hypervisor hook so that the spapr
code can provide the correct value of SDR1 to be pushed to KVM each
time kvmppc_put_books_sregs() is called.
It allows to get rid of all the hacking in the spapr/kvmppc code and
it fixes migration of nested KVM PR.

These fields were used to manually handle IO requests that weren't aligned
to a sector boundary before this feature was supported by the block API.
Once the block API changed to support byte-aligned IO requests, the macio
controller was switched over to use it in commit be1e343 but these fields
were accidentally left behind. Remove them, including the initialisation
in DBDMA_init().

Instead we can now instantiate the MAC_DBDMA object directly within the
macio device. We also add the DBDMA device as a child property so that
it is possible to retrieve later.

One of the reasons macio_ide_register_dma() needs to exist is because the
channel id isn't passed into the MACIO_IDE object. Pass in the channel id
using a qdev property to remove this requirement.

Using a standard QOM object link we can pass a reference to the MAC_DBDMA
controller to the MACIO_IDE object which removes the last external parameter
to macio_ide_register_dma().
