Subject: [PATCH] i386/cpu: Don't add unavailable_features to
env->user_features
Features unavailable due to absent of their dependent features should
not be added to env->user_features. env->user_features only contains the
feature explicity specified with -feature/+feature by user.

Date: Tue, 8 Sep 2020 11:18:50 +0000
Subject: [PATCH 08/11] migration: fix multifd_send_pages() next channel
multifd_send_pages() loops around the available channels,
the next channel to use between two calls to multifd_send_pages() is stored
inside a local static variable, next_channel.
It works well, except if the number of channels decreases between two calls
to multifd_send_pages(). In this case, the loop can try to access the
data of a channel that doesn't exist anymore.
The problem can be triggered if we start a migration with a given number of
channels and then we cancel the migration to restart it with a lower number.
This ends generally with an error like:
qemu-system-ppc64: .../util/qemu-thread-posix.c:77: qemu_mutex_lock_impl: Assertion `mutex->initialized' failed.
This patch fixes the error by capping next_channel with the current number
of channels before using it.

Subject: [PATCH] target/i386: add VMX features to named CPU models
This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:
bits = {
'INS/OUTS instruction information': ['FEAT_VMX_BASIC', 'MSR_VMX_BASIC_INS_OUTS'],

"load IA32_PAT". Those have to be fixed by hand.

From 290ed17e639a67a9faf4a18b1b5973f9535bace4 Mon Sep 17 00:00:00 2001
From: Paolo Bonzini <pbonzini@redhat.com>

Subject: [PATCH] target/i386: add VMX features
Add code to convert the VMX feature words back into MSR values,
allowing the user to enable/disable VMX features as they wish. The same
infrastructure enables support for limiting VMX features in named
CPU models.

Subject: [PATCH] target/i386: add two missing VMX features for Skylake and
CascadeLake Server
They are present in client (Core) Skylake but pasted wrong into the server
SKUs.

Subject: [PATCH] target/i386: disable VMX features if nested=0
If kvm does not support VMX feature by nested=0, the kvm_vmx_basic
can't get the right value from MSR_IA32_VMX_BASIC register, which
make qemu coredump when qemu do KVM_SET_MSRS.
The coredump info:
error: failed to set MSR 0x480 to 0x0
kvm_put_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed.

Subject: [PATCH] target/i386: do not set unsupported VMX secondary execution
controls
Commit 048c95163b4 ("target/i386: work around KVM_GET_MSRS bug for
secondary execution controls") added a workaround for KVM pre-dating
commit 6defc591846d ("KVM: nVMX: include conditional controls in /dev/kvm
KVM_GET_MSRS") which wasn't setting certain available controls. The
workaround uses generic CPUID feature bits to set missing VMX controls.
It was found that in some cases it is possible to observe hosts which
have certain CPUID features but lack the corresponding VMX control.
In particular, it was reported that Azure VMs have RDSEED but lack
VMX_SECONDARY_EXEC_RDSEED_EXITING; attempts to enable this feature
bit result in QEMU abort.
Resolve the issue but not applying the workaround when we don't have
to. As there is no good way to find out if KVM has the fix itself, use
95c5c7c77c ("KVM: nVMX: list VMX MSRs in KVM_GET_MSR_INDEX_LIST") instead
as these [are supposed to] come together.
Fixes: 048c95163b4 ("target/i386: work around KVM_GET_MSRS bug for secondary execution controls")

Subject: [PATCH] target/i386: expand feature words to 64 bits
VMX requires 64-bit feature words for the IA32_VMX_EPT_VPID_CAP
and IA32_VMX_BASIC MSRs. (The VMX control MSRs are 64-bit wide but
actually have only 32 bits of information).

mark_unavailable_features
The next patch will add a different reason for filtering features, unrelated
to host feature support. Extract a new function that takes care of disabling
the features and optionally reporting them.

Subject: [PATCH] target/i386: introduce generic feature dependency mechanism
Sometimes a CPU feature does not make sense unless another is
present. In the case of VMX features, KVM does not even allow
setting the VMX controls to some invalid combinations.
Therefore, this patch adds a generic mechanism that looks for bits
that the user explicitly cleared, and uses them to remove other bits
from the expanded CPU definition. If these dependent bits were also
explicitly *set* by the user, this will be a warning for "-cpu check"
and an error for "-cpu enforce". If not, then the dependent bits are
cleared silently, for convenience.
With VMX features, this will be used so that for example
"-cpu host,-rdrand" will also hide support for RDRAND exiting.

Subject: [PATCH] target/i386: work around KVM_GET_MSRS bug for secondary
execution controls
Some secondary controls are automatically enabled/disabled based on the CPUID
values that are set for the guest. However, they are still available at a
global level and therefore should be present when KVM_GET_MSRS is sent to
/dev/kvm.
Unfortunately KVM forgot to include those, so fix that.
