The PAGE_SIZE macro is causing trouble on Alpine Linux since it
clashes with a macro from a system header there. We already have
the TARGET_PAGE_SIZE, TARGET_PAGE_MASK and TARGET_PAGE_BITS macros
in QEMU anyway, so let's simply replace the PAGE_SIZE, PAGE_MASK
and PAGE_SHIFT macro with their TARGET_* counterparts.

Let's enable storage keys lazily under TCG, just as we do under KVM.
Only fairly old Linux versions actually make use of storage keys, so it
can be kind of wasteful to allocate quite some memory and track
changes and references if nobody cares.
We have to make sure to flush the TLB when enabling storage keys after
the VM was already running: otherwise it might happen that we don't
catch references or modifications afterwards.
Add proper documentation to all callbacks.
The kvm-unit-tests skey tests keeps on working with this change.

When a subchannel becomes pending with unit exception, start
pending (and for that matter, halt or clear pending) are not
removed in the actl. Device active and subchannel active,
however, are (due to the subchannel becoming status pending

The other conditions in the actl are only cleared when the

This patch switches to initialize dev.nvqs from the VhostNetOptions
instead of assuming it was 2. This is useful for implementing control
virtqueue support which will be a single vhost_net structure with a
single cvq.
Note that nvqs is still set to 2 for all users and this patch does not
change functionality.

commit c0e427d6eb ("hw/acpi/ich9: Enable ACPI PCI hot-plug") removed all
uses of find_i440fx() function. This has been replaced by the more generic call
acpi_get_i386_pci_host() which maybe able to find the root bus both for i440fx
machine type as well as for the q35 machine type. There seems to be no more any
need to maintain a i440fx specific version of the api call. Remove it.

vhost_set_backend_type() gets called only in vhost.c, so we can move the

kernel_ops, to match the other VhostOps in vhost-backend.h.
The VhostOps constants now make more sense in vhost.h

Now that we have "acpi-pci-hotplug-with-bridge-support" PIIX4 PM property being
used for both q35 and i440fx machine types, it is better that we defined this
property string at a single place within a header file like other PIIX4
properties. We can then use this single definition at all the places that needs
it instead of duplicating the string everywhere. While at it, this change also
adds a definition for "acpi-root-pci-hotplug" PIIX4 PM property and uses
this definition at all places that were formally using the string value.

With the introduction of the batch hinting, meaningless batches can be
created with no IOTLB updates if the memory region was skipped by
vhost_vdpa_listener_skipped_section. This is the case of host notifiers
memory regions, device un/realize, and others. This causes the vdpa
device to receive dma mapping settings with no changes, a possibly
expensive operation for nothing.
To avoid that, VHOST_IOTLB_BATCH_BEGIN hint is delayed until we have a
meaningful (not skipped section) mapping or unmapping operation, and
VHOST_IOTLB_BATCH_END is not written unless at least one of _UPDATE /
_INVALIDATE has been issued.
v3:
* Use a bool instead of a counter avoiding potential number wrapping
* Fix bad check on _commit
* Move VHOST_BACKEND_F_IOTLB_BATCH check to
vhost_vdpa_iotlb_batch_begin_once
v2 (from RFC):
* Rename misleading name
* Abstract start batching function for listener_add/del

The stellaris-gptm timer currently uses system_clock_scale for one of
its timer modes where the timer runs at the CPU clock rate. Make it
use a Clock input instead.
We don't try to make the timer handle changes in the clock frequency
while the downcounter is running. This is not a change in behaviour
from the previous system_clock_scale implementation -- we will pick
up the new frequency only when the downcounter hits zero. Handling
dynamic clock changes when the counter is running would require state
that the current gptm implementation doesn't have.

Because there is only one board using this SoC, we convert the SoC

is wired up".
When the systick device starts honouring its clock inputs, this will

It is quite common for a clock tree to involve possibly programmable
clock multipliers or dividers, where the frequency of a clock is for
instance divided by 8 to produce a slower clock to feed to a
particular device.
Currently we provide no convenient mechanism for modelling this. You
can implement it by having an input Clock and an output Clock, and
manually setting the period of the output clock in the period-changed
callback of the input clock, but that's quite clunky.
This patch adds support in the Clock objects themselves for setting a
multiplier or divider. The effect of setting this on a clock is that
when the clock's period is changed, all the children of the clock are
set to period * multiplier / divider, rather than being set to the
same period as the parent clock.

The v7M systick timer can be programmed to run from either of
two clocks:
* an "external reference clock" (when SYST_CSR.CLKSOURCE == 0)
* the main CPU clock (when SYST_CSR.CLKSOURCE == 1)
Our implementation currently hardwires the external reference clock
to be 1MHz, and allows boards to set the main CPU clock frequency via
the global 'system_clock_scale'. (Most boards set that to a constant
value; the Stellaris boards allow the guest to reprogram it via the
board-specific RCC registers).
As the first step in converting this to use the Clock infrastructure,
add input clocks to the systick device for the reference clock and
the CPU clock. The device implementation ignores them; once we have
made all the users of the device correctly wire up the new Clocks we
will switch the implementation to use them and ignore the old
system_clock_scale.
This is a migration compat break for all M-profile boards, because of
the addition of the new clock objects to the vmstate struct.
