2ebc21216f hw/pci-host: save/restore pci host config register
The pci host config register is used to save PCI address for
read/write config data. If guest writes a value to config register,
and then QEMU pauses the vcpu to migrate, after the migration, the guest
will continue to write pci config data, and the write data will be ignored
because of new qemu process losing the config register state.

To trigger the bug:
1. guest is booting in seabios.
2. guest enables the SMRAM in seabios:piix4_apmc_smm_setup, and then
   expects to disable the SMRAM by pci_config_writeb.
3. after guest writes the pci host config register, QEMU pauses vcpu
   to finish migration.
4. guest write of config data(0x0A) fails to disable the SMRAM because
   the config register state is lost.
5. guest continues to boot and crashes in ipxe option ROM due to SMRAM
   in enabled state.

Example Reproducer:

step 1. Make modifications to seabios and qemu for increase reproduction
efficiency, write 0xf0 to 0x402 port notify qemu to stop vcpu after
0x0cf8 port wrote i440 configure register. qemu stop vcpu when catch
0x402 port wrote 0xf0.

c22aba1963 virtio-mem-pci: force virtio version 1
Trying to run simple virtio-mem-pci examples currently fails with

    requested-size=300M: device is modern-only, use disable-legacy=on
due to the added safety checks in 9b3a35ec82 ("virtio: verify that legacy
support is not accidentally on").

As noted by Conny, we have to force virtio version 1. While at it, use
qdev_realize() to set the parent bus and realize - like most other
virtio-*-pci implementations.

We should check whether the user-specified node-name actually refers to
a node.  The simplest way to do that is to use bdrv_lookup_bs() instead
of bdrv_find_node() (the former wraps the latter, and produces an error

The primary purpose of this change is to clean up
machine.py's console_socket property to return a single type,
a ConsoleSocket.

ConsoleSocket now derives from a socket, which means that
in the default case (of not draining), machine.py
will see the same behavior as it did prior to ConsoleSocket.

Plain MAP_FIXED has the undesirable behaviour of splatting exiting

We should be using MAP_FIXED_NOREPLACE. As this isn't always available
we need to potentially check the returned address to see if the kernel
gave us what we asked for.

163b3d1af2 target/i386: floatx80: avoid compound literals in static initializers
Quoting ISO C99 6.7.8p4, "All the expressions in an initializer for an
object that has static storage duration shall be constant expressions or
string literals".

The compound literal produced by the make_floatx80() macro is not such a
constant expression, per 6.6p7-9. (An implementation may accept it,
according to 6.6p10, but is not required to.)

Therefore using "floatx80_zero" and make_floatx80() for initializing
"f2xm1_table" and "fpatan_table" is not portable. And gcc-4.8 in RHEL-7.6
actually chokes on them:

> target/i386/fpu_helper.c:871:5: error: initializer element is not constant
>      { make_floatx80(0xbfff, 0x8000000000000000ULL),
>      ^

We've had the make_floatx80_init() macro for this purpose since commit
3bf7e40ab9 ("softfloat: fix for C99", 2012-03-17), so let's use that
macro again.

Fixes: ff57bb7b63 ("target/i386: reimplement fpatan using floatx80 operations")

aef92d87c5 pseries: fix kvmppc_set_fwnmi()
QEMU issues the ioctl(KVM_CAP_PPC_FWNMI) on the first vCPU.

If the first vCPU is currently running, the vCPU mutex is held
and the ioctl() cannot be done and waits until the mutex is released.
This never happens and the VM is stuck.

To avoid this deadlock, issue the ioctl on the same vCPU doing the
RTAS call.

The problem can be reproduced by booting a guest with several vCPUs
(the probability to have the problem is (n - 1) / n,  n = # of CPUs),
and then by triggering a kernel crash with "echo c >/proc/sysrq-trigger".

On the reboot, the kernel hangs after:

88f8307457 tpm_emulator: Report an error if chardev is missing
This patch fixes the odd error reporting when trying to send a file
descriptor to the TPM emulator if one has not passed a valid chardev.

$ x86_64-softmmu/qemu-system-x86_64 -tpmdev emulator,id=tpm0
qemu-system-x86_64: -tpmdev emulator,id=tpm0: tpm-emulator: Failed to send CMD_SET_DATAFD: Success
qemu-system-x86_64: -tpmdev emulator,id=tpm0: tpm-emulator: Could not cleanly shutdown the TPM: Success

This is the new error report:

$ x86_64-softmmu/qemu-system-x86_64 -tpmdev emulator,id=tpm0
qemu-system-x86_64: -tpmdev emulator,id=tpm0: tpm-emulator: parameter 'chardev' is missing

This change does not hide the display of supported TPM types if a non-existent type is passed:

$ x86_64-softmmu/qemu-system-x86_64 -tpmdev nonexistent,id=tpm0
qemu-system-x86_64: -tpmdev nonexistent,id=tpm0: Parameter 'type' expects a TPM backend type

d64072c0ac Revert "tpm: Clean up error reporting in tpm_init_tpmdev()"
This reverts commit d10e05f15d.

We report some -tpmdev failures, but then continue as if all was fine.
Reproducer:

    $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -chardev null,id=tpm0 -tpmdev emulator,id=tpm0,chardev=chrtpm -device tpm-tis,tpmdev=tpm0
    qemu-system-x86_64: -tpmdev emulator,id=tpm0,chardev=chrtpm: tpm-emulator: tpm chardev 'chrtpm' not found.
    qemu-system-x86_64: -tpmdev emulator,id=tpm0,chardev=chrtpm: tpm-emulator: Could not cleanly shutdown the TPM: No such file or directory
    QEMU 5.0.90 monitor - type 'help' for more information
    (qemu) qemu-system-x86_64: -device tpm-tis,tpmdev=tpm0: Property 'tpm-tis.tpmdev' can't find value 'tpm0'
    $ echo $?
    1

This is a regression caused by commit d10e05f15d "tpm: Clean up error
reporting in tpm_init_tpmdev()".  It's incomplete: be->create(opts)
continues to use error_report(), and we don't set an error when it
fails.

I figure converting the create() methods to Error would make some
sense, but I'm not sure it's worth the effort right now.  Revert the
broken commit instead, and add a comment to tpm_init_tpmdev().

Straightforward conflict in tpm.c resolved.

9b52b17ba5 configure: Allow to build tools without pixman
If pixman is not installed, it is currently not possible to run:

 .../configure  --disable-system --enable-tools

Seems like there was a dependency from one of the required source
files to pixman in the past, but since commit 1ac0206b2a
("qemu-timer.c: Trim list of included headers"), this dependency
should be gone. Thus allow to compile the tools without pixman now.

8d942986be hw: Only compile the usb-dwc2 controller if it is really needed
The USB_DWC2 switch is currently "default y", so it is included in all
qemu-system-* builds, even if it is not needed. Even worse, it does a
"select USB", so USB devices are now showing up as available on targets
that do not support USB at all. This sysbus device should only be
included by the boards that need it, i.e. by the Raspi machines.

192cf54ac5 qapi/error: Check format string argument in error_*prepend()

error_prepend() checks its format string argument, but
error_propagate_prepend() does not. Fix by addint the format
attribute to error_propagate_prepend() and error_vprepend().

This would have caught the bug fixed in the previous commit.

d664548328 s390x/s390-virtio-ccw: fix loadparm property getter
The function machine_get_loadparm() is supposed to produce a C-string,
that is a NUL-terminated one, but it does not. ElectricFence can detect
this problem if the loadparm machine property is used.

Let us make the returned string a NUL-terminated one.

d1bb69db4c s390x/protvirt: allow to IPL secure guests with -no-reboot
Right now, -no-reboot prevents secure guests from running. This is
correct from an implementation point of view, as we have modeled the
transition from non-secure to secure as a program directed IPL. From
a user perspective, this is not the behavior of least surprise.

We should implement the IPL into protected mode similar to the
functions that we use for kdump/kexec. In other words, we do not stop
here when -no-reboot is specified on the command line. Like function 0
or function 1, function 10 is not a classic reboot. For example, it
can only be called once. Before calling it a second time, a real
reboot/reset must happen in-between. So function code 10 is more or
less a state transition reset, but not a "standard" reset or reboot.

0baa4b445e KVM: fix CPU reset wrt HF2_GIF_MASK
HF2_GIF_MASK is set in env->hflags2 unconditionally on CPU reset
(see x86_cpu_reset()) but when calling KVM_SET_NESTED_STATE,
KVM_STATE_NESTED_GIF_SET is only valid for nSVM as e.g. nVMX code
looks like

if (kvm_state->hdr.vmx.vmxon_pa == -1ull) {
    if (kvm_state->flags & ~KVM_STATE_NESTED_EVMCS)
        return -EINVAL;
}

Also, when adjusting the environment after KVM_GET_NESTED_STATE we
need not reset HF2_GIF_MASK on VMX as e.g. x86_cpu_pending_interrupt()
expects it to be set.

Alternatively, we could've made env->hflags2 SVM-only.

09e0cd7737 This PR contains a few RISC-V fixes.
The main fix is the correction of the goldfish RTC time. On top of that
 some small fixes to the recently added vector extensions have been added
 (including an assert that fixed a coverity report). There is a change in
 the SiFive E debug memory size to match hardware. Finally there is a fix
 for PMP accesses.
