19800265d4 hw/riscv: virt: Map high mmio for PCIe
Some peripherals require 64-bit PCI address, so let's map the high
mmio space for PCIe.

For RV32, the address is hardcoded to below 4 GiB from the highest
accessible physical address. For RV64, the base address depends on
top of RAM and is aligned to its size which is using 16 GiB for now.

cfeb8a17c8 hw/riscv: virt: Limit RAM size in a 32-bit system
RV32 supports 34-bit physical address hence the maximum RAM size
should be limited. Limit the RAM size to 10 GiB, which leaves
some room for PCIe high mmio space.

For 32-bit host, this is not needed as machine->ram_size cannot
represent a RAM size that big. Use a #if size test to only do
the size limitation for the 64-bit host.

145b299139 hw/riscv: sifive_u: Add QSPI0 controller and connect a flash
This adds the QSPI0 controller to the SoC, and connects an ISSI
25WP256 flash to it. The generation of corresponding device tree
source fragment is also added.

Since the direct memory-mapped mode is not supported by the SiFive
SPI model, the <reg> property does not populate the second group
which represents the memory mapped address of the SPI flash.

With this commit, upstream U-Boot for the SiFive HiFive Unleashed
board can boot on QEMU 'sifive_u' out of the box. This allows users
to develop and test the recommended RISC-V boot flow with a real
world use case: ZSBL (in QEMU) loads U-Boot SPL from SPI flash to
L2LIM, then U-Boot SPL loads the payload from SPI flash that is
combined with OpenSBI fw_dynamic firmware and U-Boot proper.

Specify machine property `msel` to 6 to allow booting from the SPI
flash. U-Boot spl is directly loaded via `-bios`, and subsequent
payload is stored in the SPI flash image. Example command line:

$ qemu-system-riscv64 -nographic -M sifive_u,msel=6 -smp 5 -m 8G \
    -bios u-boot-spl.bin -drive file=spi-nor.img,if=mtd

10509e1095 hw/block: m25p80: Add ISSI SPI flash support
This adds the ISSI SPI flash support. The number of dummy cycles in
fast read, fast read dual output and fast read quad output commands
is currently using the default 8. Likewise, the same default value
is used for fast read dual/quad I/O command. Per the datasheet [1],
the number of dummy cycles is configurable, but this is not modeled
at present.

For flash whose size is larger than 16 MiB, the sequence of 3-byte
address along with EXTADD bit in the bank address register (BAR) is
not supported. We assume that guest software always uses op codes
with 4-byte address sequence. Fortunately, this is the case for both
U-Boot and Linux spi-nor drivers.

QPI (Quad Peripheral Interface) that supports 2-cycle instruction
has different default values for dummy cycles of fast read family
commands, and is unsupported at the time being.

b5a087b071 ui/console: Add placeholder flag to message surface
The surfaces created with former qemu_create_message_surface
did not display the content from the guest and always contained
simple messages describing the reason.

A display backend may want to hide the window showing such a
surface. This change renames the function to
qemu_create_placeholder_surface, and adds "placeholder" flag; the
display can check the flag to decide to do anything special like
hiding the window.

1d8d014e93 vhost: simplify vhost_dev_init() fail_busyloop label
Requiring a conditional for every goto is tedious:

  if (busyloop_timeout) {
      goto fail_busyloop;
  } else {
      goto fail;
  }

Move the conditional to into the fail_busyloop label so that it's safe
to jump to this label unconditionally.

This change makes the migrate_add_blocker() error case more consistent.
It jumped to fail_busyloop unconditionally whereas the memslots limits
error case was conditional.

b52fa0ea45 hw/pci: Have safer pcie_bus_realize() by checking error path
While pci_bus_realize() currently does not use the Error* argument,
it would be an error to leave pcie_bus_realize() setting bus->flags
if pci_bus_realize() had failed.

Fix by using a local Error* and return early (propagating the error)
if pci_bus_realize() failed.

fb59288239 virtio-net: handle zero mac for a vdpa peer
Some mlx vdpa devices with kernels at least up to 5.11 currently present
0 as their MAC address.  This is because they have not been
  pre-configured with a MAC: they have a learning bridge and only learn
the MAC once guest is up.  Kernel patches and tools to allow programming
the MAC from host are being developed. For now - since these
combinations exist in the field - let's detect zero mac and just try to
proceed with the mac from the qemu command line.

This makes the guest use this MAC to send packets in turn teaching
the MAC to the card, and things work.

TODO:
report the actual MAC from QEMU commad line in the info message.
TODO:
detect that a (non-zero) hardware MAC does not match QEMU command line
and fail init.

0a343a5add i386/acpi: restore device paths for pre-5.1 vms
After fixing the _UID value for the primary PCI root bridge in
af1b80ae it was discovered that this change updates Windows
configuration in an incompatible way causing network configuration
failure unless DHCP is used. More details provided on the list:

https://lists.gnu.org/archive/html/qemu-devel/2021-02/msg08484.html

This change reverts the _UID update from 1 to 0 for q35 and i440fx
VMs before version 5.2 to maintain the original behaviour when
upgrading.

guest only for rerror=report.  However, when rerror/werror are 'stop'
we still don't want the host to be involved on every UNIT ATTENTION

6f1a5c37db virtio-scsi: don't process IO on fenced dataplane
If virtio_scsi_dataplane_start fails, there is a small window when it drops the
aio lock (in aio_wait_bh_oneshot) and the dataplane's AIO handler can
still run during that window.

This is done after the dataplane was marked as fenced, thus we use this flag
to avoid it doing any IO.

e3fb55f065 hw/i386: declare ACPI mother board resource for MMCONFIG region
Declare PNP0C01 device to reserve MMCONFIG region to conform to the
spec better and play nice with guest BIOSes/OSes.

According to PCI Firmware Specification[0], MMCONFIG region must be
reserved by declaring a motherboard resource. It's optional to reserve
the region in memory map by Int 15 E820h or EFIGetMemoryMap.
Guest Linux checks if the MMCFG region is reserved by bios memory map
or ACPI resource. If it's not reserved, Linux falls back to legacy PCI
configuration access.

TDVF [1] [2] doesn't reserve MMCONFIG the region in memory map.
On the other hand OVMF reserves it in memory map without declaring a
motherboard resource. With memory map reservation, linux guest uses
MMCONFIG region. However it doesn't comply to PCI Firmware
specification.

[0] PCI Firmware specification Revision 3.2
  4.1.2 MCFG Table Description table 4-2 NOTE 2
  If the operating system does not natively comprehend reserving the
  MMCFG region, The MMCFG region must e reserved by firmware. ...
  For most systems, the mortheroard resource would appear at the root
  of the ACPI namespace (under \_SB)...
  The resource can optionally be returned in Int15 E820h or
  EFIGetMemoryMap as reserved memory but must always be reported
  through ACPI as a motherboard resource

6be8cf56bc acpi/core: always set SCI_EN when SMM isn't supported
If SMM is not supported, ACPI fixed hardware doesn't support
legacy-mode. ACPI-only platform. Where SCI_EN in PM1_CNT register is
always set.
The bit tells OS legacy mode(SCI_EN cleared) or ACPI mode(SCI_EN set).

With the next patch (setting fadt.smi_cmd = 0 when smm isn't enabled),
guest Linux tries to switch to ACPI mode, finds smi_cmd = 0, and then
fails to initialize acpi subsystem. This patch proactively fixes it.

This patch changes guest ABI. To keep compatibility, use
"smm-compat" introduced by earlier patch. If the property is true,
disable new behavior.

PM1 Eanble Registers
> For ACPI-only platforms (where SCI_EN is always set)

df72184ec1 pcie: don't set link state active if the slot is empty
When the pcie slot is initialized, by default PCI_EXP_LNKSTA_DLLLA
(Data Link Layer Link Active) is set in PCI_EXP_LNKSTA
(Link Status) without checking if the slot is empty or not.

This is confusing for the kernel because as it sees the link is up
it tries to read the vendor ID and fails:

This is really a problem with virtio-net failover that hotplugs a VFIO
card during the boot process. The kernel can shutdown the slot while
QEMU is hotplugging it, and this likely ends by an automatic unplug of
the card. At the end of the boot sequence the card has disappeared.

To fix that, don't set the "Link Active" state in the init function, but
rely on the plug function to do it, as the mechanism has already been
introduced by 2f2b18f60b.

97ca9c5920 failover: really display a warning when the primary device is not found
In failover_add_primary(), we search the id of the failover device by
scanning the list of the devices in the opts list to find a device with
a failover_pair_id equals to the id of the virtio-net device.

If the failover_pair_id is not found, QEMU ignores the primary
device silently (which also means it will not be hidden and
it will be enabled directly at boot).

After that, we search the id in the opts list to do a qdev_device_add()
with it. The device will be always found as otherwise we had exited
before, and thus the warning is never displayed.

Fix that by moving the error report to the first exit condition.
Also add a g_assert() to be sure the compiler will not complain
about a possibly NULL pointer.

00e7b12995 virtio-net: add missing object_unref()
failover_add_primary() calls qdev_device_add() and doesn't unref
the device. Because of that, when the device is unplugged a reference
is remaining and prevents the cleanup of the object.

This prevents to be able to plugin back the failover primary device,
with errors like:

  (qemu) device_add vfio-pci,host=0000:41:00.0,id=hostdev0,bus=root.3,failover_pair_id=net0
  (qemu) device_del hostdev0

We can check with "info qtree" and "info pci" that the device has been removed, and then:

  (qemu) device_add vfio-pci,host=0000:41:00.0,id=hostdev1,bus=root.3,failover_pair_id=net0
  Error: vfio 0000:41:00.0: device is already attached
  (qemu) device_add vfio-pci,host=0000:41:00.0,id=hostdev0,bus=root.3,failover_pair_id=net0
