Create a helper function qxl_dirty_one_surface() to mark a single qxl
surface as dirty.  Use the new qxl_get_check_slot_offset function and
lookup the memory region from the slot instead of assuming the surface
is stored in vram.

Use the new helper function in qxl_dirty_surfaces, for both primary and
off-screen surfaces.  For off-screen surfaces this is no functional
change.  For primary surfaces this will dirty only the memory actually
used instead of the whole surface0 region.  It will also work correctly
in case the guest places the primary surface in vram instead of the
surface0 region (linux kms driver does that).

ppc patch queue for 2016-07-05

Here's the current ppc, sPAPR and related drivers patch queue.

  * The big addition is dynamic DMA window support (this includes some
    core VFIO changes)
  * There are also several fixes to the MMU emulation for bugs
    introduced with the HV mode patches
  * Several other bugfixes and cleanups

Changes in v2:
  I messed up and forgot to make a fix in the last patch which BenH
  pointed out (introduced by my rebasing).  That's fixed in this
  version, and I'm replacing the tag in place with the revised
  version.

ppc_hash64_pteg_search() now decodes a PTEs page size encoding, which it
didn't previously do.  This means we're now double decoding the page size
because we check it int he fault path after ppc64_hash64_htab_lookup()
returns.

To avoid this duplication have ppc_hash64_pteg_search() and
ppc_hash64_htab_lookup() return the page size from the PTE and use that in
the callers instead of decoding again.

ppc_hash64_pteg_search() explicitly checks each HPTE's VALID and
SECONDARY bits, then uses the HPTE64_V_COMPARE() macro to check the B field
and AVPN.  However, a small tweak to HPTE64_V_COMPARE() means we can check
all of these bits at once with a suitable ptem value.  So, consolidate all
the comparisons for simplicity.

The architecture specifies that when searching a PTEG for PTEs, entries
with a page size encoding that's not valid for the current segment should
be ignored, continuing the search.

The current implementation does this with ppc_hash64_pte_size_decode()
which is a very incomplete implementation of this check.  We already have
code to do a full and correct page size decode in hpte_page_shift().

This patch moves hpte_page_shift() so it can be used in
ppc_hash64_pteg_search() and adjusts the latter's parameters to include
a full SLBE instead of just a segment page shift.

This adds support for Dynamic DMA Windows (DDW) option defined by
the SPAPR specification which allows to have additional DMA window(s)

The "ddw" property is enabled by default on a PHB but for compatibility
the pseries-2.6 machine and older disable it.
This also creates a single DMA window for the older machines to
maintain backward migration.

This implements DDW for PHB with emulated and VFIO devices. The host
kernel support is required. The advertised IOMMU page sizes are 4K and
64K; 16M pages are supported but not advertised by default, in order to
enable them, the user has to specify "pgsz" property for PHB and
enable huge pages for RAM.

The existing linux guests try creating one additional huge DMA window
with 64K or 16MB pages and map the entire guest RAM to. If succeeded,
the guest switches to dma_direct_ops and never calls TCE hypercalls
(H_PUT_TCE,...) again. This enables VFIO devices to use the entire RAM
and not waste time on map/unmap later. This adds a "dma64_win_addr"
property which is a bus address for the 64bit window and by default
set to 0x800.0000.0000.0000 as this is what the modern POWER8 hardware
uses and this allows having emulated and VFIO devices on the same bus.

This adds 4 RTAS handlers:
* ibm,query-pe-dma-window
* ibm,create-pe-dma-window
* ibm,remove-pe-dma-window
* ibm,reset-pe-dma-window
These are registered from type_init() callback.

These RTAS handlers are implemented in a separate file to avoid polluting
spapr_iommu.c with PCI.

This changes sPAPRPHBState::dma_liobn to an array to allow 2 LIOBNs
and updates all references to dma_liobn. However this does not add
64bit LIOBN to the migration stream as in fact even 32bit LIOBN is
rather pointless there (as it is a PHB property and the management
software can/should pass LIOBNs via CLI) but we keep it for the backward
migration support.

New VFIO_SPAPR_TCE_v2_IOMMU type supports dynamic DMA window management.
This adds ability to VFIO common code to dynamically allocate/remove
DMA windows in the host kernel when new VFIO container is added/removed.

This adds a helper to vfio_listener_region_add which makes
VFIO_IOMMU_SPAPR_TCE_CREATE ioctl and adds just created IOMMU into
the host IOMMU list; the opposite action is taken in
vfio_listener_region_del.

When creating a new window, this uses heuristic to decide on the TCE table
levels number.

This should cause no guest visible change in behavior.

This makes use of the new "memory registering" feature. The idea is
to provide the userspace ability to notify the host kernel about pages
which are going to be used for DMA. Having this information, the host
kernel can pin them all once per user process, do locked pages
accounting (once) and not spent time on doing that in real time with
possible failures which cannot be handled nicely in some cases.

This adds a prereg memory listener which listens on address_space_memory
and notifies a VFIO container about memory which needs to be
pinned/unpinned. VFIO MMIO regions (i.e. "skip dump" regions) are skipped.

The feature is only enabled for SPAPR IOMMU v2. The host kernel changes
are required. Since v2 does not need/support VFIO_IOMMU_ENABLE, this does
not call it when v2 is detected and enabled.

This enforces guest RAM blocks to be host page size aligned; however
this is not new as KVM already requires memory slots to be host page
size aligned.

Signed-off-by: NDavid Gibson <david@gibson.dropbear.id.au>

The sPAPR TCE tables manage 2 copies when VFIO is using an IOMMU -
a guest view of the table and a hardware TCE table. If there is no VFIO
presense in the address space, then just the guest view is used, if
this is the case, it is allocated in the KVM. However since there is no
support yet for VFIO in KVM TCE hypercalls, when we start using VFIO,
we need to move the guest view from KVM to the userspace; and we need
to do this for every IOMMU on a bus with VFIO devices.

This implements the callbacks for the sPAPR IOMMU - notify_started()
reallocated the guest view to the user space, notify_stopped() does
the opposite.

This removes explicit spapr_tce_set_need_vfio() call from PCI hotplug
path as the new callbacks do this better - they notify IOMMU at
the exact moment when the configuration is changed, and this also
includes the case of PCI hot unplug.

During CPU core realization, we create all the thread objects and parent
them to the core object in a loop. However, the realization of thread
objects is done separately by walking the threads of a core using
object_child_foreach(). With this, there is no guarantee on the order
in which the child thread objects get realized. Since CPU device tree
properties are currently derived from the CPU thread object, we assume
thread0 of the core to be the representative thread of the core when
creating device tree properties for the core. If thread0 is not the
first thread that gets realized, then we would end up having an
incorrect dt_id for the core and this causes hotplug failures from
the guest.

Fix this by realizing each thread object by walking the core's thread
object list thereby ensuring that thread0 and other threads are always
realized in the correct order.

Future TODO: CPU DT nodes are per-core properties and we should
ideally base the creation of CPU DT nodes on core objects rather than
the thread objects.
