* The minimum toolchain requirements have increased for some architectures:
- For x86, GCC 5.1 and Binutils 2.25, or Clang/LLVM 11
- For ARM32 and ARM64, GCC 5.1 and Binutils 2.25
- For RISC-V, GCC 12.2 and Binutils 2.39
* Debian Trixie added to CI. Debian Bullseye retired from CI for RISC-V due
to the baseline change.
* Linux based device model stubdomains are now fully supported.
* New dependency on library json-c 0.15 or later, the toolstack will prefer it
to `YAJL` when available.
* Introduce libxenmanage as a stable library, replacing xenstored's
dependency on unstable libraries.
* Introduce new PDX compression algorithm to cope with Intel Sierra Forest and
Granite Rapids having sparse memory maps.
* Support of qemu-traditional has been removed.
* The in-tree oxenstored is deprecated and will be removed in a future
version of Xen. It is moving into the Xapi project
https://github.com/xapi-project/oxenstored so it can be maintained in line
with the other Ocaml projects in the Xen ecosystem.
* On x86:
- Restrict the cache flushing done as a result of guest physical memory map
manipulations and memory type changes.
- Allow controlling the MTRR cache attribute of the Xen platform PCI device
BAR for HVM guests, to improve performance of guests using it to map the
grant table or foreign memory.
- Allow configuring the number of altp2m tables per domain via vm.cfg.
- Option to attempt to fixup p2m page-faults on PVH dom0.
- Resizable BARs is supported for PVH dom0.
- Support PCI passthrough for HVM domUs when dom0 is PVH (note SR-IOV
capability usage is not yet supported on PVH dom0).

- refresh replace-obsolete-network-configuration-commands-in-s.patch
to not accidently enter untested brctl code paths
- bsc#985503 - vif-route.patch is obsolete since Xen 4.15
- bsc#1035231 - remove SUSE specific changes for save/restore/migrate
to reduce future maintainence overhead. The bottleneck during
migration is the overhead of mapping HVM domU pages into dom0,
which was not addressed by these changes.
The options --abort_if_busy --max_iters --min_remaining will not
be recognized anymore by xl or virsh.

xen-4.20.0-testing-src.tar.bz2
- New Features
* On Arm:
- Experimental support for Armv8-R.
- Support for NXP S32G3 Processors Family and NXP LINFlexD UART driver.
- Basic handling for SCMI requests over SMC using Shared Memory, by allowing
forwarding the calls to EL3 FW if coming from hwdom.
- Support for LLC (Last Level Cache) coloring.
* On x86:
- xl suspend/resume subcommands.
- Changed Features
* Fixed blkif protocol specification for sector sizes different than 512b.
* The dombuilder in libxenguest no longer un-gzips secondary modules, instead
leaving this to the guest kernel to do in guest context.
* On x86:
- Prefer ACPI reboot over UEFI ResetSystem() run time service call.
- Switched the xAPIC flat driver to use physical destination mode for external
interrupts instead of logical destination mode.
- Removed Features
* On x86:
- Support for running on Xeon Phi processors.
- Removed the `ucode=allow-same` command line option.
- Removed x2APIC Cluster Mode for external interrupts. x2APIC Physical and
Mixed Modes are still available.
- Dropped patches
xsa466.patch
- Move /etc/bash_completion.d/xl back to %_datadir/bash-completion/completions

xen-4.18.0-testing-src.tar.bz2
* Repurpose command line gnttab_max_{maptrack_,}frames options so they don't
cap toolstack provided values.
* Ignore VCPUOP_set_singleshot_timer's VCPU_SSHOTTMR_future flag. The only
known user doesn't use it properly, leading to in-guest breakage.
* The "dom0" option is now supported on Arm and "sve=" sub-option can be used
to enable dom0 guest to use SVE/SVE2 instructions.
* Physical CPU Hotplug downgraded to Experimental and renamed "ACPI CPU
Hotplug" for clarity
* On x86, support for features new in Intel Sapphire Rapids CPUs:
- PKS (Protection Key Supervisor) available to HVM/PVH guests.
- VM-Notify used by Xen to mitigate certain micro-architectural pipeline
livelocks, instead of crashing the entire server.
- Bus-lock detection, used by Xen to mitigate (by rate-limiting) the system
wide impact of a guest misusing atomic instructions.
* xl/libxl can customize SMBIOS strings for HVM guests.
* Add support for AVX512-FP16 on x86.
* On Arm, Xen supports guests running SVE/SVE2 instructions. (Tech Preview)
* On Arm, add suport for Firmware Framework for Arm A-profile (FF-A) Mediator
(Tech Preview)
* Add Intel Hardware P-States (HWP) cpufreq driver.
* On Arm, experimental support for dynamic addition/removal of Xen device tree
nodes using a device tree overlay binary (.dtbo).
* Introduce two new hypercalls to map the vCPU runstate and time areas by
physical rather than linear/virtual addresses.
* On x86, support for enforcing system-wide operation in Data Operand
Independent Timing Mode.
* The project has now officially adopted 6 directives and 65 rules of MISRA-C.
* On x86, the "pku" command line option has been removed. It has never
