Dario Faggioli e8c9119cb5 Accepting request 941047 from home:dfaggioli:devel:Virtualization
- Add an audio-oss sub-package
- Add some new (mostly documentation) files in the package
- Remove option --audio-drv-list because audio is detected by
  meson automatically in latest version. 
- Remove options --disable-jemalloc and --disable-tcmalloc
  which are changed in v6.2.0. 
- Update to v 6.2.0. For full release notese, see:
  * https://wiki.qemu.org/ChangeLog/6.2.

  Some notable changes:
  * virtio-mem: guest memory dumps are now fully supported, along
    with pre-copy/post-copy migration and background guest snapshots
  * QMP: support for nw DEVICE_UNPLUG_GUEST_ERROR to detect
    guest-reported hotplug failures
  * TCG: improvements to TCG plugin argument syntax, and multi-core
    support for cache plugin
  * 68k: improved support for Apple’s NuBus, including ability to
    load declaration ROMs, and slot IRQ support
  * ARM: macOS hosts with Apple Silicon CPUs now support ‘hvf’
    accelerator for AArch64 guests
  * ARM: emulation support for Fujitsu A64FX processor model
  * ARM: emulation support for kudo-mbc machine type
  * ARM: M-profile MVE extension is now supported for Cortex-M55
  * ARM: ‘virt’ machine now supports an emulated ITS (Interrupt
    Translation Service) and supports more than 123 CPUs in
    emulation mode
  * ARM: xlnx-zcu102 and xlnx-versal-virt machines now support
    BBRAM and eFUSE devices
  * PowerPC: improved POWER10 support for the ‘powernv’ machine type
  * PowerPC: initial support for POWER10 DD2.0 CPU model
  * PowerPC: support for FORM2 PAPR NUMA descriptions for ‘pseries’ machine type
  * RISC-V: support for Zb[abcs] instruction set extensions
  * RISC-V: support for vhost-user and numa mem options across all boards
  * RISC-V: SiFive PWM support
  * x86: support for new Snowridge-v4 CPU model
  * x86: guest support for Intel SGX
  * x86: AMD SEV guests now support measurement of kernel binary when doing
    direct kernel boot (not using a bootloader)

Subject: Raise soft address space limit to hard limit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
For SLES we want users to be able to use large memory configurations
with KVM without fiddling with ulimit -Sv.
