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

unbound limits for max_event_channels
|
|
1023 is too low for a three digit value of vcpus
|
|
it is difficult to make the value depend on the number of vcpus
|
|
adding devices at runtime also needs event channels
|
|
|
|
But, having an unbound value (of 128k) may have a negative effect on XSA-344.
|
|
|
|
Therefore, just let the built-in default depend on the number of vcpus.
