Allow retrieving only a subset of statistics. This can be useful
for example in order to plot a subset of the statistics many times
a second: KVM publishes ~40 statistics for each vCPU on x86; retrieving
and serializing all of them would be useless.
Another use will be in HMP in the following patch; implementing the
filter in the backend is easy enough that it was deemed okay to make
this a public interface.
Example:
{ "execute": "query-stats",
"arguments": {
"target": "vcpu",
"vcpus": [ "/machine/unattached/device[2]",
"/machine/unattached/device[4]" ],
"providers": [
{ "provider": "kvm",
"names": [ "l1d_flush", "exits" ] } } }
{ "return": {
"vcpus": [
{ "path": "/machine/unattached/device[2]"
"providers": [
{ "provider": "kvm",
"stats": [ { "name": "l1d_flush", "value": 41213 },
{ "name": "exits", "value": 74291 } ] } ] },
{ "path": "/machine/unattached/device[4]"
"providers": [
{ "provider": "kvm",
"stats": [ { "name": "l1d_flush", "value": 16132 },
{ "name": "exits", "value": 57922 } ] } ] } ] } }

Allow retrieving the statistics from a specific provider only.
This can be used in the future by HMP commands such as "info
sync-profile" or "info profile". The next patch also adds
filter-by-provider capabilities to the HMP equivalent of
query-stats, "info stats".
Example:
{ "execute": "query-stats",
"arguments": {
"target": "vm",
"providers": [
{ "provider": "kvm" } ] } }
The QAPI is a bit more verbose than just a list of StatsProvider,
so that it can be subsequently extended with filtering of statistics
by name.
If a provider is specified more than once in the filter, each request
will be included separately in the output.

Gathering statistics is important for development, for monitoring and
for performance measurement. There are tools such as kvm_stat that do
this and they rely on the _user_ knowing the interesting data points
rather than the tool (which can treat them as opaque).
The commands introduced in this commit introduce QMP support for
querying stats; the goal is to take the capabilities of these tools
and making them available throughout the whole virtualization stack,
so that one can observe, monitor and measure virtual machines without
having shell access + root on the host that runs them.
query-stats returns a list of all stats per target type (only VM
and vCPU to start); future commits add extra options for specifying
stat names, vCPU qom paths, and providers. All these are used by the
HMP command "info stats". Because of the development usecases around
statistics, a good HMP interface is important.
query-stats-schemas returns a list of stats included in each target
type, with an option for specifying the provider. The concepts in the
schema are based on the KVM binary stats' own introspection data, just
translated to QAPI.
There are two reasons to have a separate schema that is not tied to
the QAPI schema. The first is the contents of the schemas: the new
introspection data provides different information than the QAPI data,
namely unit of measurement, how the numbers are gathered and change
(peak/instant/cumulative/histogram), and histogram bucket sizes.
There's really no reason to have this kind of metadata in the QAPI
introspection schema (except possibly for the unit of measure, but
there's a very weak justification).
Another reason is the dynamicity of the schema. The QAPI introspection
data is very much static; and while QOM is somewhat more dynamic,
generally we consider that to be a bug rather than a feature these days.
On the other hand, the statistics that are exposed by QEMU might be
passed through from another source, such as KVM, and the disadvantages of
manually updating the QAPI schema for outweight the benefits from vetting
the statistics and filtering out anything that seems "too unstable".
Running old QEMU with new kernel is a supported usecase; if old QEMU
cannot expose statistics from a new kernel, or if a kernel developer
needs to change QEMU before gathering new info from the new kernel,
then that is a poor user interface.
The framework provides a method to register callbacks for these QMP
commands. Most of the work in fact is done by the callbacks, and a
large majority of this patch is new QAPI structs and commands.
Examples (with KVM stats):
- Query all VM stats:
{ "execute": "query-stats", "arguments" : { "target": "vm" } }
{ "return": [
{ "provider": "kvm",
"stats": [
{ "name": "max_mmu_page_hash_collisions", "value": 0 },
{ "name": "max_mmu_rmap_size", "value": 0 },
{ "name": "nx_lpage_splits", "value": 148 },
... ] },
{ "provider": "xyz",
"stats": [ ... ] }
] }
- Query all vCPU stats:
{ "execute": "query-stats", "arguments" : { "target": "vcpu" } }
{ "return": [
{ "provider": "kvm",
"qom_path": "/machine/unattached/device[0]"
"stats": [
{ "name": "guest_mode", "value": 0 },
{ "name": "directed_yield_successful", "value": 0 },
{ "name": "directed_yield_attempted", "value": 106 },
... ] },
{ "provider": "kvm",
"qom_path": "/machine/unattached/device[1]"

{ "name": "directed_yield_successful", "value": 0 },
{ "name": "directed_yield_attempted", "value": 106 },

This change adds a new member, refresh_rate to QemuUIInfo in
include/ui/console.h. It represents the refresh rate of the
physical display backend, and it is more appropriate than
GUI update interval as the refresh rate which the emulated device
reports:
- sdl may set GUI update interval shorter than the refresh rate
of the physical display to respond to user-generated events.
- sdl and vnc aggressively changes GUI update interval, but
a guests is typically not designed to respond to frequent
refresh rate changes, or frequent "display mode" changes in
general. The frequency of refresh rate changes of the physical
display backend matches better to the guest's expectation.
QemuUIInfo also has other members representing "display mode",
which makes it suitable for refresh rate representation. It has
a throttling of update notifications, and prevents frequent changes
of the display mode.

The sysbus floppy controllers (devices sysbus-fdc and sun-fdtwo)
don't support DMA. The core floppy controller code expects this to
be indicated by setting FDCtrl::dma_chann to -1. This used to be
done in the device instance_init functions sysbus_fdc_initfn() and
sun4m_fdc_initfn(), but in commit 1430759ec3 we refactored this code
and accidentally lost the setting of dma_chann.
For sysbus-fdc this has no ill effects because we were redundantly
also setting dma_chann in fdctrl_init_sysbus(), but for sun-fdtwo
this means that guests which try to enable DMA on the floppy
controller will cause QEMU to crash because FDCtrl::dma is NULL.
Set dma_chann to -1 in the common instance init, and remove the
redundant code in fdctrl_init_sysbus() that is also setting it.
There is a six-year-old FIXME comment in the jazz board code to the
effect that in theory it should support doing DMA via a custom DMA
controller. If anybody ever chooses to fix that they can do it by
adding support for setting both FDCtrl::dma_chann and FDCtrl::dma.
(A QOM link property 'dma-controller' on the sysbus device which can
be set to an instance of IsaDmaClass is probably the way to go.)

This removes the last of the CXL code from the MachineState where it
is visible to all Machines to only those that support CXL (currently i386/pc)
As i386/pc always support CXL now, stop allocating the state independently.
Note the pxb register hookup code runs even if cxl=off in order to detect
pxb_cxl host bridges and fail to start if any are present as they won't

As the CXLState will no long be accessible via MachineState
at time of PXB_CXL realization, come back later from the machine specific
code to fill in the missing memory region setup. Only at this stage
is it possible to check if cxl=on, so that check is moved to this
later point.
Note that for multiple host bridges, the allocation order of the
register spaces is changed. This will be reflected in ACPI CEDT.
Stubs are added to handle case of CONFIG_PXB=n for machines that
call these functions.
The bus walking logic is common to all machines so add a utility
function + stub to cxl-host*.

Paolo Bonzini requested this change to simplify the ongoing
effort to allow machine setup entirely via RPC.
Includes shortening the command line form cxl-fixed-memory-window
to cxl-fmw as the command lines are extremely long even with this
change.
The json change is needed to ensure that there is
a CXLFixedMemoryWindowOptionsList even though the actual
element in the json is never used. Similar to existing
SgxEpcProperties.
Update qemu-options.hx to reflect that this is now a -machine
parameter. The bulk of -M / -machine parameters are documented
under machine, so use that in preference to M.
Update cxl-test and bios-tables-test to reflect new parameters.

node in _CRS. The rest of IPMI inplementations (ISA based)
do not need path at all. Instead of passing through a full path
use relative path to point to smbus-ipmi's parent node, it will
let follow up patches to create IPMI device AML in a generic
way instead of current ad-hoc way. (i.e. AML will be generated
the same way it's done for other ISA device, and smbus will be
converted to generate AML for its slave devices the same way
as ISA)

To extend the same idea to other devices, add TYPE_ACPI_DEV_AML_IF

allow get rid of some data-mining and ad-hoc AML building,
