Hi all,
The next community call is on Thursday 6th June 2024, which clashes with
Xen Summit in Lisbon.
I propose we move the call a week later to *Thursday 13th June 2024, 4-5pm
(UK time). *

A long-standing usability sub-optimality with xenalyze is the
necessity to specify `--svm-mode` when analyzing AMD processors. This
fundamentally comes about because the same trace event ID is used for
both VMX and SVM, but the contents of the trace must be interpreted
differently.
Instead, alloc
To unify certain common sanity checks, checks are done very early in
processing based only on the top-level type.
Unfortunately, when TRC_HVM_EMUL was introduced, it broke some of the
assumptions about how the top-level types worked. Namely, traces of
this type will show up outside of HVM context

Move the macros and defines to a new header so they can be re-used.

With the exception of one case in read_bndcfgu() which can use ilog2(),
the *_POS defines are unused.
X86_XCR0_X87 is the name used by both the SDM and APM, rather than
X86_XCR0_FP.

This is a tangle, but it's a small step in the right direction.
xstate_init() is shortly going to want data from the Raw policy.
calculate_raw_cpu_policy() is sufficiently separate from the other policies to
be safe to do.

Make use of xstate_uncompressed_size() helper rather than maintaining the
running calculation while accumulating feature components.
The rest of the CPUID data can come direct from the raw cpu policy. All
per-component data form an ABI through the behaviour of the X{SAVE,RSTOR}*
instructions.

The clobbering of this_cpu(xcr0) and this_cpu(xss) to architecturally invalid
values is to force the subsequent set_xcr0() and set_msr_xss() to reload the
hardware register.
While XCR0 is reloaded in xstate_init(), MSR_XSS isn't. This causes
get_msr_xss() to return the invalid value, and logic of
First, if XSAVE is available in hardware but not visible to the guest, the
dynamic leaves shouldn't be filled in.
Second, the comment concerning XSS state is wrong. VT-x doesn't manage
host/guest state automatically, but there is provision for "host only" bits to
be set, so the implications are s
We're soon going to need a compressed helper of the same form.
The size of the uncompressed image depends on the single element with the
largest offset + size. Sadly this isn't always the element with the largest
index.
Name the per-xstate-component cpu_policy struture, for legibility of the log
Right now, xstate_ctxt_size() performs a cross-check of size with CPUID in for
every call. This is expensive, being used for domain create/migrate, as well
as to service certain guest CPUID instructions.
Instead, arrange to check the sizes once at boot. See the code comments for
details. Right
This has grown somewhat from v2, but is better for it IMO.
The headline change is patch 2 performing all the cross-checking at boot time.
This turned into needing prepare the Raw CPU policy earlier on boot (to avoid
further-adding to scheme we're already looking to retire).

Factor out policy getters/setters from both (CPUID and MSR) policy override
functions. Additionally, use host policy rather than featureset when
preparing the cur policy, saving one hypercall and several lines of
boilerplate.
No functional change intended.

v3
The idea is to use xc_cpu_policy_t as a single object containing both the
serialised and deserialised forms of the policy. Note that we need lengths
for the arrays, as the serialised policies may be shorter than the array
capacities.
* Add the serialised lengths to the struct so we can distinguish
v2 -> v3:
* Style adjustments
* Revert of loop index scope refactors
v1 -> v2:
* Removed xc_cpu_policy from xenguest.h (dropped v1/patch1)
* Added accessors for xc_cpu_policy so the serialised form can be extracted.
* Modified xen-cpuid to use accessors.
