Patch logs MCE AO, AR messages injected to guest or taken by QEMU itself.
We print the QEMU address for guest MCEs, helps on hypervisors that have
another source of MCE logging like mce log, and when they go missing.
For example we found these QEMU logs:
September 26th 2019, 17:36:02.309 Droplet-153258224: Guest MCE Memory Error at qemu addr 0x7f8ce14f5000 and guest 3d6f5000 addr of type BUS_MCEERR_AR injected qemu-system-x86_64 amsN ams3nodeNNNN
September 27th 2019, 06:25:03.234 Droplet-153258224: Guest MCE Memory Error at qemu addr 0x7f8ce14f5000 and guest 3d6f5000 addr of type BUS_MCEERR_AR injected qemu-system-x86_64 amsN ams3nodeNNNN
The first log had a corresponding mce log entry, the second didnt (logging
thresholds) we can infer from second entry same PA and mce type.

commit 369b41359af46bded5799c9ef8be2b641d92e043 broke timer interrupt
reinjection when there is no period change by the guest.
In that case, old_period is 0, which ends up zeroing irq_coalesced
(counter of reinjected interrupts).
The consequence is Windows 7 is unable to synchronize time via NTP.
Easily reproducible by playing a fullscreen video with cirrus and VNC.
Fix by not updating s->irq_coalesced when old_period is 0.

From: Vitaly Kuznetsov <vkuznets@redhat.com>
Hyper-V TLFS specifies this enlightenment as:
"NoNonArchitecturalCoreSharing - Indicates that a virtual processor will never
share a physical core with another virtual processor, except for virtual
processors that are reported as sibling SMT threads. This can be used as an
optimization to avoid the performance overhead of STIBP".
However, STIBP is not the only implication. It was found that Hyper-V on
KVM doesn't pass MD_CLEAR bit to its guests if it doesn't see
NoNonArchitecturalCoreSharing bit.
KVM reports NoNonArchitecturalCoreSharing in KVM_GET_SUPPORTED_HV_CPUID to
indicate that SMT on the host is impossible (not supported of forcefully
disabled).
Implement NoNonArchitecturalCoreSharing support in QEMU as tristate:
'off' - the feature is disabled (default)
'on' - the feature is enabled. This is only safe if vCPUS are properly
pinned and correct topology is exposed. As CPU pinning is done outside
of QEMU the enablement decision will be made on a higher level.
'auto' - copy KVM setting. As during live migration SMT settings on the
source and destination host may differ this requires us to add a migration
blocker.

+3.17. hv-no-nonarch-coresharing=on/off/auto
+===========================================
+This enlightenment tells guest OS that virtual processors will never share a
+physical core unless they are reported as sibling SMT threads. This information
+is required by Windows and Hyper-V guests to properly mitigate SMT related CPU
+vulnerabilities.
+When the option is set to 'auto' QEMU will enable the feature only when KVM
+reports that non-architectural coresharing is impossible, this means that
+hyper-threading is not supported or completely disabled on the host. This
+setting also prevents migration as SMT settings on the destination may differ.
+When the option is set to 'on' QEMU will always enable the feature, regardless
+of host setup. To keep guests secure, this can only be used in conjunction with
+exposing correct vCPU topology and vCPU pinning.

From: Thomas Huth <thuth@redhat.com>
The %m format specifier is an extension from glibc - and when compiling
QEMU for NetBSD, the compiler correctly complains, e.g.:
/home/qemu/qemu-test.ELjfrQ/src/util/main-loop.c: In function 'sigfd_handler':
/home/qemu/qemu-test.ELjfrQ/src/util/main-loop.c:64:13: warning: %m is only
allowed in syslog(3) like functions [-Wformat=]
printf("read from sigfd returned %zd: %m\n", len);
^
Let's use g_strerror() here instead, which is an easy-to-use wrapper
around the thread-safe strerror_r() function.
While we're at it, also convert the "printf()" in main-loop.c into
the preferred "error_report()".

To: qemu-devel; +Cc: Sergio Lopez
Split up PCMachineState and PCMachineClass and derive X86MachineState
and X86MachineClass from them. This allows sharing code with non-PC
x86 machine types.

From: Sergio Lopez <slp@redhat.com>
As a last step into splitting PCMachineState and deriving
X86MachineState from it, make the functions previously extracted from
pc.c to x86.c independent from PCMachineState, using X86MachineState
instead.

qboot is a minimalist x86 firmware for booting Linux kernels. It does
the mininum amount of work required for the task, and it's able to
boot both PVH images and bzImages without relying on option roms.
This characteristics make it an ideal companion for the microvm
machine type.

+====================
+microvm Machine Type
+====================
+
+``microvm`` is a machine type inspired by ``Firecracker`` and
+constructed after its machine model.
+
+It's a minimalist machine type without ``PCI`` nor ``ACPI`` support,
+designed for short-lived guests. microvm also establishes a baseline
+for benchmarking and optimizing both QEMU and guest operating systems,
+since it is optimized for both boot time and footprint.
+
+
+Supported devices
+-----------------
+
+The microvm machine type supports the following devices:
+
+- ISA bus
+- i8259 PIC (optional)
+- i8254 PIT (optional)
+- MC146818 RTC (optional)
+- One ISA serial port (optional)
+- LAPIC
+- IOAPIC (with kernel-irqchip=split by default)
+- kvmclock (if using KVM)
+- fw_cfg
+- Up to eight virtio-mmio devices (configured by the user)
+
+
+Limitations
+-----------
+
+Currently, microvm does *not* support the following features:
+
+ - PCI-only devices.
+ - Hotplug of any kind.
+ - Live migration across QEMU versions.
+
+
+Using the microvm machine type
+------------------------------
+
+Machine-specific options
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+It supports the following machine-specific options:
+
+- microvm.x-option-roms=bool (Set off to disable loading option ROMs)
+- microvm.pit=OnOffAuto (Enable i8254 PIT)
+- microvm.isa-serial=bool (Set off to disable the instantiation an ISA serial port)
+- microvm.pic=OnOffAuto (Enable i8259 PIC)
+- microvm.rtc=OnOffAuto (Enable MC146818 RTC)
+- microvm.auto-kernel-cmdline=bool (Set off to disable adding virtio-mmio devices to the kernel cmdline)
+
+
+Boot options
+~~~~~~~~~~~~
+
+By default, microvm uses ``qboot`` as its BIOS, to obtain better boot
+times, but it's also compatible with ``SeaBIOS``.
+
+As no current FW is able to boot from a block device using
+``virtio-mmio`` as its transport, a microvm-based VM needs to be run
+using a host-side kernel and, optionally, an initrd image.
+
+
+Running a microvm-based VM
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default, microvm aims for maximum compatibility, enabling both
+legacy and non-legacy devices. In this example, a VM is created
+without passing any additional machine-specific option, using the
+legacy ``ISA serial`` device as console::
+
+ $ qemu-system-x86_64 -M microvm \
+ -enable-kvm -cpu host -m 512m -smp 2 \
+ -kernel vmlinux -append "earlyprintk=ttyS0 console=ttyS0 root=/dev/vda" \
+ -nodefaults -no-user-config -nographic \
+ -serial stdio \
+ -drive id=test,file=test.img,format=raw,if=none \
+ -device virtio-blk-device,drive=test \
+ -netdev tap,id=tap0,script=no,downscript=no \
+ -device virtio-net-device,netdev=tap0
+
+While the example above works, you might be interested in reducing the
+footprint further by disabling some legacy devices. If you're using
+``KVM``, you can disable the ``RTC``, making the Guest rely on
+``kvmclock`` exclusively. Additionally, if your host's CPUs have the
+``TSC_DEADLINE`` feature, you can also disable both the i8259 PIC and
+the i8254 PIT (make sure you're also emulating a CPU with such feature
+in the guest).
+
+This is an example of a VM with all optional legacy features
+disabled::
+
+ $ qemu-system-x86_64 \
+ -M microvm,x-option-roms=off,pit=off,pic=off,isa-serial=off,rtc=off \
+ -enable-kvm -cpu host -m 512m -smp 2 \
+ -kernel vmlinux -append "console=hvc0 root=/dev/vda" \
+ -nodefaults -no-user-config -nographic \
+ -chardev stdio,id=virtiocon0 \
+ -device virtio-serial-device \
+ -device virtconsole,chardev=virtiocon0 \
+ -drive id=test,file=test.img,format=raw,if=none \
+ -device virtio-blk-device,drive=test \
+ -netdev tap,id=tap0,script=no,downscript=no \
+ -device virtio-net-device,netdev=tap0

From: Laurent Vivier <lvivier@redhat.com>
Trying to reboot a VM while a migration is running can
move to the prelaunch state (because of the reset) while
the runstate is in finish migrate state.
As the logical step after the finish migrate is postmigrate,
this can create an invalid state transition from prelaunch state
to postmigrate state and this raises an error and aborts:
invalid runstate transition: 'prelaunch' -> 'postmigrate'
As we are not able to manage reset in finish migrate state the
best we can do is to ignore any changes and delay them until

From: Tao Xu <tao3.xu@intel.com>
UMONITOR, UMWAIT and TPAUSE are a set of user wait instructions.
This patch adds support for user wait instructions in KVM. Availability
of the user wait instructions is indicated by the presence of the CPUID
feature flag WAITPKG CPUID.0x07.0x0:ECX[5]. User wait instructions may
be executed at any privilege level, and use IA32_UMWAIT_CONTROL MSR to
set the maximum time.
The patch enable the umonitor, umwait and tpause features in KVM.
Because umwait and tpause can put a (psysical) CPU into a power saving
state, by default we dont't expose it to kvm and enable it only when
guest CPUID has it. And use QEMU command-line "-overcommit cpu-pm=on"
(enable_cpu_pm is enabled), a VM can use UMONITOR, UMWAIT and TPAUSE
instructions. If the instruction causes a delay, the amount of time
delayed is called here the physical delay. The physical delay is first
computed by determining the virtual delay (the time to delay relative to
the VM’s timestamp counter). Otherwise, UMONITOR, UMWAIT and TPAUSE cause
an invalid-opcode exception(#UD).

index E1H to determines the maximum time in TSC-quanta that the processor
can reside in either C0.1 or C0.2.
This patch is to Add support for save/load IA32_UMWAIT_CONTROL MSR in

By extracting pc_gsi_create() and pc_i8259_create() we removed
the access to "kvm_i386.h" from the machine code. We can now
remove it.

Devices/boards wanting to use the MC146818 RTC don't need
the knowledge its internal registers. Move the "mc146818rtc_regs.h"
inclusion to mc146818rtc.c where it is required.
We can not move this file from include/hw/timer/ to hw/timer/ for
local inclusion because the ACPI FADT table use the RTC_CENTURY
register address.

From: Wei Yang <richardw.yang@linux.intel.com>
There are three page size in qemu:
real host page size
host page size
target page size
All of them have dedicate variable to represent. For the last two, we
use the same form in the whole qemu project, while for the first one we
use two forms: qemu_real_host_page_size and getpagesize().
qemu_real_host_page_size is defined to be a replacement of
getpagesize(), so let it serve the role.
[Note] Not fully tested for some arch or device.

Move it out of pc.c since it is strictly tied to TCG. This is
almost exclusively code movement, the next patch will implement
IGNNE.

Change the handling of port F0h writes and FPU exceptions to implement IGNNE.
The implementation mixes a bit what the chipset and processor do in real
hardware, but the effect is the same as what happens with actual FERR#
and IGNNE# pins: writing to port F0h asserts IGNNE# in addition to lowering
FP_IRQ; while clearing the SE bit in the FPU status word deasserts IGNNE#.

x86_register_ferr_irq() is defined in target/i386/fpu_helper.c,
which is only built if CONFIG_TCG, but the callers don't
seem to be similarly guarded and there's no stub fallback.
thanks

Indeed, thanks. I'll add an "if (tcg_enabled())" since this feature is
not supported by accelerators other than TCG.

Paolo, since the "Split timer <-> rtc" series got merged via
the trivial tree, you need to squash this fix to patch #33
("mc146818rtc: Include mc146818rtc_regs.h directly in
mc146818rtc.c") to avoid build failure:

Hi; Coverity points out a memory leak in this commit
(CID 1407218):

Here we allocate memory for cmdline...

...but fw_cfg_modify_string() takes a copy of the string it's passed,
so we still have ownership of 'cmdline' and need to free it here
to avoid a leak.
