- 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.

* 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.

Subject: libxc sr number of iterations
|
|
|
|
Reduce default value of --max_iters from 5 to 1.
|
|
The workload within domU will continue to produce dirty pages.
|
|
It is unreasonable to expect any slowdown during migration.
|
|
Now there is one initial copy of all memory, one instead of five
|
|
iterations for dirty memory, and a final copy iteration prior move.
