qemu: Update to 6.0.0

* Add zstd dependency.

== System emulation ==

=== Incompatible changes ===

Consult the [ 'Removed features' ] page for details of suggested replacement functionality

* The deprecated ''pc-1.0'', ''pc-1.1'', ''pc-1.2'' and ''pc-1.3'' machine types have been removed (they likely could not be used for live migration from old QEMU versions anymore anyway). Use a newer ''pc-i440fx-...'' machine type instead.
* TileGX emulation has been removed without replacement
* The ''change'' QMP command has been removed. Use ''blockdev-change-medium'' or ''change-vnc-password'' instead.
* The ''-show-cursor'' option has been removed. Use ''-display sdl,show-cursor=on'' instead.
* The ''-realtime'' option has been removed. Use ''-overcommit mem-lock=on|off' instead.
* The ''-tb-size'' option has been removed. Use ''-accel tcg,tb-size=...'' instead.
* The configure script --enable/disable-git-update args have been replaced with --with-git-submodules
* The ''-usbdevice audio'' option has been removed.  Use ''-device usb-audio'' instead.
* The ''-usbdevice ccid'' option has been removed with no replacement
* The ''-vnc'' parameter ''acl'' option, and ''acl_*'' monitor commands have been removed.
* The ''pretty'' option is no longer accepted when used with the human monitor
* The ''change'' QMP command has been removed. Use ''blockdev-change-medium'' or ''change-vnc-password'' instead.
* The ''query-events'' QMP command has been removed
* The ''migrate_set_speed'', ''migrate_set_downtime'' and ''migrate-set-cache-size'' QMP/HMP commands have been removed.
* The ''query-cpus'' QMP command has been removed
* The ''arch'' field in the ''query-cpus-fast'' command has been removed
* The ''-chardev'' parameter ''wait'' option is no longer accepted for socket clients
* The ''ide-drive'' device type has been removed
* The ''scsi-disk'' device type has been removed
* The ''encryption_key_missing'' field has been removed from block device info data
* The ''status'' field has been removed from dirty bitmap info
* The ''dirty-bitmaps'' field has been removed from the ''BlockInfo'' struct
* The ''file'' block driver no longer permits use with block devices
* The use of ''-global'' to set floppy controllers is removed. Use ''-device floppy,...'' instead.
* The ''-drive'' option must now use ''if=none'' for drives the onboard device does not pick up.
* The ''object-add'' QMP command member ''props'' has been removed.  Its contents may be used with less nesting instead.
* The mips ''fulong2e'' machine alias has been removed. Use ''fuloong2e'' instead.

=== New deprecated options and features ===

Consult the [ "Deprecated Features"] chapter of the QEMU System Emulation User's Guide for further details of the deprecations and their suggested replacements.

* The --enable-fips option has been deprecated. Consumers wishing to have FIPS compliance must build QEMU with libcrypt and gnutls, NOT nettle.
* The ''-writeconfig'' option has been deprecated. The functionality of ''-writeconfig'' is limited and the code does not even try to detect cases where it prints incorrect syntax (for example if values have a quote in them). It will be removed without replacement.
* Boolean parameters such as ''share=on'' / ''share=off'' could be written in short form as ''share'' and ''noshare''.  This is now deprecated and will cause a warning.
* ''-chardev'' backend aliases ''tty'' and ''parport'' are aliases that will be removed. Instead, the actual backend names ''serial'' and ''parallel'' should be used.
* The ''delay'' option for socket character devices is now deprecated.
* Userspace local APIC with KVM (''-M kernel-irqchip=off'')
* hexadecimal sizes with scaling multipliers (e.g. ''0x20M'')
* ''-spice password=string'' is deprecated now. Use ''password-secret'' option instead.
* ''opened'' property of ''rng-*'' objects
* ''loaded'' property of ''secret'' and ''secret_keyring''
* MIPS ''Trap-and-Emulate'' KVM support

* Emulation of the ARMv8.4-DIT extension is now supported. (Note that QEMU's implementation does not in fact provide any timing guarantees; emulation of the extension is purely to support guests which query its presence and work with the PSTATE.DIT bit.)
* Emulation of the ARMv8.5-MemTag extension is now supported for linux-user. (It was already supported for system emulation.)
* xlnx-zynqmp boards now support the Xilinx ZynqMP CAN controllers

=== HPPA ===

=== Microblaze ===

=== MIPS ===
* Loongson-3 "virt" machine added

=== Nios2 ===

=== OpenRISC ===

* powernv machine type now defaults to 1GiB of RAM
* powernv now allows an external BMC
* pseries will now send MEM_UNPLUG_ERROR QAPI message in cases where it can detect that a memory unplug has failed
* pseries will now allow cpu unplug requests to be retried, even if the guest hasn't responded to them yet.
  * This will re-signal the guest, which might an unplug to complete which the guest previous rejected

=== Renesas RX ===

=== Renesas SH ===

=== RISC-V ===
* Improve the sifive_u DTB generation
* Add QSPI NOR flash to Microchip PFSoC

=== s390 ===
* Linux kernels built with clang-11 and clang-12 now work correctly under tcg

=== SPARC ===

=== TileGX ===

* TileGX has been removed without replacement.TileGX was only implemented in linux-user mode, but support for this CPU was removed from the upstream Linux kernel in 2018, and it has also been dropped from glibc, so there is no new Linux development taking place with this architecture, rendering the linux-user mode emulation rather useless. For running older binaries, users can simply use older versions of QEMU.

=== Tricore ===
* Added Triboard with tc27x SoC

=== x86 ===
* TCG can emulate the PKS feature (protection keys for supervisor pages).
* Intel PT can now be exposed to KVM guests when <code>CPUID.(EAX=14,ECX=0).ECX[LIP]</code> (bit 31) is 1. Previous versions only supported Intel PT when LIP=0
* New <code>sev-inject-launch-secret</code> QMP command
* The WHPX accelerator supports accelerated APIC ("-accel whpx,kernel-irqchip=on")
* The microvm machine type got a second (optional) ioapic for the virtio-mmio irq lines, which in turn allows 24 (instead of 8) virtio-mmio devices.
* Support for running SEV-ES encrypted guests.

=== Xtensa ===

=== Device emulation and assignment ===

==== ACPI ====
* new ''-machine'' options ''oem-id'' and ''oem-table-id'' to allow setting custom values for ''OEM ID'' and ''OEM table ID'' ACPI table fields
* in QEMU 5.1, PCI root UID changed to from 1 to 0 for all x86 machine types, this caused issues in Windows guest with virtio devices being re-enumeraed as new devices. QEMU 6.0 fixes it by reverting UID to 1 for 5.1 and older machine types. See commit 0a343a5add75 for details. For 5.2 and later machine types it might be necessary to reconfigure/reinstall Windows VM, if used disk image was created on 5.1 and older machine types.
* Support for user provided PCI NIC index on ''pc'' machine type with help of new ''acpi-index'' PCI device option. For linux guests, It lets user to use ''onboard'' naming scheme ''enoX'' where X is set with ''acpi-index'' option. It makes NIC naming independent from which PCI slot it is plugged in. Works with cold and hot-plugged NICs, as long as used PCI bus is managed by ACPI PCI hotplug (which is enabled for PCI root bus and bridges present at boot time by default on latest ''pc'' machine type ).

==== Audio ====

==== Block devices ====
* virtio-blk reports <tt>--device virtio-blk-pci,discard_granularity=</tt> in the virtio-blk <tt>discard_sector_alignment</tt> configuration space field so that guests with new machine types can take advantage of this information. Previously virtio-blk devices reported <tt>--device virtio-blk-pci,logical_block_size=</tt> instead.

==== Graphics ====

==== Input devices ====

==== IPMI ====

==== Multi-process QEMU ====

* The experimental <code>-machine x-remote</code> and <code>-device x-pci-proxy-dev</code> options have been added to support out-of-process device emulation. Currently only the <code>lsi53c895</code> SCSI device can be emulated in a separate process. Please see [ the documentation] and [[Features/MultiProcessQEMU]] for details on this experimental feature, which is still subject to change.

==== Network devices ====

==== NVDIMM ====

* nvdimm devices will check that <code>-device nvdimm,unarmed=on</code>  option is used when using <code>-object memory-backend-file,readonly=on</code>

==== NVMe ====

===== Emulated NVMe Controller =====

==== PCI/PCIe ====

* The 'pvpanic-pci' device is a PCI-device version of the 'pvpanic' ISA device, which can be used on systems with only PCI and no ISA bus as a mechanism for the guest to inform QEMU that it has paniced.

==== SCSI ====
* Rework of the ESP SCSI emulation to allow mixed FIFO/(P)DMA commands along with various other fixes

==== SD card ====

==== SMBIOS ====

==== TPM ====

==== USB ====

* Support for writing usb traffic to package capture files for inspection with wireshark has been added.  Use the new pcap=<file> property added to all usb devices to enable this.

==== VFIO ====

==== virtio ====

==== Xen ====

* A new [ guest loader] which allows testing of Xen-like hypervisors booting kernels without messing around with firmware/bootloaders

==== fw_cfg ====

==== 9pfs ====

==== virtiofs ====
* Security fix for CVE-2020-35517 - prevent opening of special files
* Security fix for CVE-2021-20263 - when used with xattrmap, drop remapped security.capability
* Performance improvements with new guest kernel feature FUSE_KILLPRIV_V2

==== Semihosting ====
* Added support for RiscV (ARM style s= Character devices ===

=== Crypto subsystem ===

==== experimental qmp interface ====

=== GUI ===
* vnc: support for cursors with alpha channel has been added.
* vnc: support for extended desktop resize has been added.  With virtio-vga the guest displab representation for SVE registers

=== TCG Plugins ===

* New API for querying details about HW access
* Bug fix to avoid double counting some instructions when using -icount

=== Host support ===

=== Memory backends ===

* hostmem-file: added readonly=lation to NBD_STATE_HOLE.
* ''qemu-img'' gained more accurate parsing for size values.  Previously, only 53 significant digits were supported, and large sizes could end up with inadvertent rounding; now the parser supports a full 64 bits of precision.
* The ''object-add'' QMP command is now available in qemu-storage-daemon.
* qemu-storage-daemon supports a ''--pidfile'' option now
* The ''parallels'' image format driver has gained support for dirty bitmaps in read-only mode

=== Tracing ===

=== Miscellaneous ===
* The command line option ''-object'' (or ''--object'') accepts JSON input now in all binaries (system emulators and tools). In tools, it also supports non-scalar options using the dotted key syntax known from options like ''--blockdev''.
* The QMP command ''object-add'' is now covered by the QAPI schema and clients can use schema introspection to detect object types and options supported by the given QEMU binary.
* A new command line option ''-action'', with suboptions ''panic'', ''shutdown'', ''reboot'' and ''watchdog''.  ''-action'' subsumes the pre-existing options ''-no-shutdown'' (''-action panic=pause,shutdown=pause''), ''-no-reboot'' (''-action reboot=shutdown'') and ''-watchdog-action''; plus, it allows the user to choose whether guest panic should pause the guest (''-action panic=pause''), shut it down (''-action panic=poweroff'', the default) or be ignored (''-action panic=none'').
* A new generic machine option ''confidential-guest-support'' was added to (partially) unify configuration for AMD SEV memory encrypt, POWER PEF and s390 Protected Virtualization, plus future methods of protecting a guest from eavesdropping by a compromised hypervisor.
* A new [ guest loader] whications.

== User-mode emulation ==
=== binfmt_misc ===

Added support of 'P' flag (preserve-argv[0])

With kernel v5.12, QEMU can detect if it is started with preserve-argv[0] flag and adjust the list of arguments accordingly.

=== Hexagon ===

Added support for the Qualcomm Hexagon processor, in linux-user mode only.

For more information, see [ our presenation from the 2019 KVM Forum]
or the [ README] file

== TCG ==

* Added support for Apple Silicon hosts (macOS)
