+/**
+ * DOC: overview
+ *
+ * In the DRM subsystem, framebuffer pixel formats are described using the
+ * fourcc codes defined in `include/uapi/drm/drm_fourcc.h`. In addition to the
+ * fourcc code, a Format Modifier may optionally be provided, in order to
+ * further describe the buffer's format - for example tiling or compression.
+ *
+ * Format Modifiers
+ * ----------------
+ *
+ * Format modifiers are used in conjunction with a fourcc code, forming a
+ * unique fourcc:modifier pair. This format:modifier pair must fully define the
+ * format and data layout of the buffer, and should be the only way to describe
+ * that particular buffer.
+ *
+ * Having multiple fourcc:modifier pairs which describe the same layout should
+ * be avoided, as such aliases run the risk of different drivers exposing
+ * different names for the same data format, forcing userspace to understand
+ * that they are aliases.
+ *
+ * Format modifiers may change any property of the buffer, including the number
+ * of planes and/or the required allocation size. Format modifiers are
+ * vendor-namespaced, and as such the relationship between a fourcc code and a
+ * modifier is specific to the modifer being used. For example, some modifiers
+ * may preserve meaning - such as number of planes - from the fourcc code,
+ * whereas others may not.
+ *
+ * Vendors should document their modifier usage in as much detail as
+ * possible, to ensure maximum compatibility across devices, drivers and
+ * applications.
+ *
+ * The authoritative list of format modifier codes is found in
+ * `include/uapi/drm/drm_fourcc.h`

KVM now supports reporting supported Hyper-V features through CPUID
(KVM_GET_SUPPORTED_HV_CPUID ioctl). Going forward, this is going to be
the only way to announce new functionality and this has already happened
with Direct Mode stimers.
While we could just support KVM_GET_SUPPORTED_HV_CPUID for new features,
it seems to be beneficial to use it for all Hyper-V enlightenments when
possible. This was we can implement 'hv-all' pass-through mode giving the
guest all supported Hyper-V features even when QEMU knows nothing about
them.
Implementation-wise we create a new kvm_hyperv_properties structure
defining Hyper-V features, get_supported_hv_cpuid()/
get_supported_hv_cpuid_legacy() returning the supported CPUID set and
a bit over-engineered hv_cpuid_check_and_set() which we will also be
used to set cpu->hyperv_* properties for 'hv-all' mode.

Let's consolidate Hyper-V features handling in hyperv_handle_properties().
The change is necessary to support pass-through 'hv-all' mode as we'll be
just copying CPUIDs from KVM instead of filling them in.

In many case we just want to give Windows guests all currently supported
Hyper-V enlightenments and that's where this new mode may come handy. We
pass through what was returned by KVM_GET_SUPPORTED_HV_CPUID.
hv_cpuid_check_and_set() is modified to also set cpu->hyperv_* flags as
we may want to check them later (and we actually do for hv_runtime,
hv_synic,...).

How is the compatibility ensured on migration between kernels reporting
different feature sets?

AFAIU we don't change anything in this regard (or, my intention was to
not change anything): hv-all is converted to the individual hv-*
properties (hv_cpuid_check_and_set()) actually sets cpu->hyperv_* flags
according to what's supported by kernel so when we migrate we will
require all these features supported.
I'll look to see that my expectations actually match the reallity,
thanks for the reminder!

Migration relies on the upper layer to run the destination QEMU with the
identical command line (except for -incoming) as the source, and QEMU is
then supposed to set up identical environment in the target VM as was in
the source, or refuse to start if that's impossible. (If I'm
misunderstanding this Dave (cc-d) may want to correct me.)
AFAICS this hv-all attribute will enable different feature sets
depending on the kernel it's run on, so the migration between different
kernels will appear to succeed, but the guest may suddenly encounter an
incompatible change in the environment.

With 'hv-all' I'm trying to achieve behavior similar to '-cpu host' and
AFAIK these VMs are migratable 'at your own risk' (if you do it directly
from qemu). Libvirt (or whatever upper layer), however, would do CPU
feature comparison and in case you have less features on the destination
host than you had on the source code it will forbid the migration. I
think if this also works for Hyper-V features than were fine.

It does sound like -cpu host, but -cpu host does come with a health
warning and we often get subtle screwups where it doesn't quite behave
the same on the two sides, also qemu now warns (and with 'enforce'
enforces) a check at it's level rather than relying on libvirt.
So hmm, yes it sounds like -cpu host, but I'd generally say it's not a
great thing to copy unless you're really really careful.
For example, in the -cpu host world people might have two machines
they think are the same - but then they find out one has HT disabled
or nesting enabled and so they're not actually the same.
I'm not sure what the equivalent bear traps are in the Hyper-V world,
but I'd be surprised if there weren't any; for example what happens
when someone upgrades one of their hosts to some minor version that
adds/removes a feature?
Also, how does libvirt figure out that the features are actually the
same - does it need a bunch of detection code?

If libvirt is involved, it's much simpler and safer to use
something like <cpu mode="host-model">, which generates a
migration-safe CPU configuration based on the current host. Live
migration support with "-cpu host" is only useful for experiments
and carefully controlled environments.
Is there a real need to make hv-all migratable? What would be
the use case, exactly? If there's no clear use case, I would
recommend making it a migration blocker.

There's no clear use-case; I noticed that we keep adding Hyper-V
enlightenments and these make Windows' life on KVM easier so we
recommend enabling them all (and, with an exception for hv-evmcs, which
I also don't enable with hv-all, I'm unawere of cases which would
require disabling certain Hyper-V enlightenments).
hv-all is mostly a convenience feature. I plan to take a look at
'host-model' to see if we can borrow some ideas from there (that would
actually be ideal - build a set of 'hv-*' enlightenments based on
capabilites of the current host) but I'm also not totally against
keeping it the way it is and making it a migration blocker for the time
being (and making it a 'developer-only' feature).

Here we're talking about Hyper-V emulation in KVM, features only get
added there, but even if it gets removed it will be detected by libvirt ...

... as I *think* it compares Feature CPUID words (and all Hyper-V
features which we enable with hv-all are there).

OK, but then you do get the same behaviour; upgrade a host to a new
kernel/qemu and get a new enlightenment, and you can't back migrate to
the older one (possibly with no warning).

Not too bad if it does, but also look at the scary command lines we get
generated full of -cpu ...+feature,+feature,-feature,....

We support "-cpu host" with libvirt because there is a genuine
functional reasont to want to use that, as you can't get precisely
the same result any other way. This isn't the case with 'hv-all',
as it doesn't offer any feature that you can't already achieve by
listing all the hv-XXX features explicitly.
As such I don't expect libvirt to use 'hv-all' at all.
There's no reason why QEMU can't support it anyway though, for the
simplicity of people launching QEMU manually. Just need to document
that migration caveat - its only safe if QEMU versions match on both
sides.

Daniel

Enlightened VMCS is enabled by writing to a field in VP assist page and
these require virtual APIC.

Synthetic timers operate in hv-time time and Windows won't use these
without SynIC.

Hyper-V on KVM can only use Synthetic timers with Direct Mode (opting for
an interrupt instead of VMBus message). This new capability is only
announced in KVM_GET_SUPPORTED_HV_CPUID.

I saw these before submitting, however, these are linux headers and we
take them as-is with scripts/update-linux-headers.sh: I don't think it
is worth it to modify these headers just to silence patchew.
