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: linux-user: Fake /proc/cpuinfo
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Fedora 17 for ARM reads /proc/cpuinfo and fails if it doesn't contain
ARM related contents. This patch implements a quick hack to expose real
/proc/cpuinfo data taken from a real world machine.
The real fix would be to generate at least the flags automatically based
on the selected CPU. Please do not submit this patch upstream until this
has happened.
