Bruce Rogers fc6feafd4e Accepting request 854151 from home:bfrogers:branches:Virtualization
- Update to v5.2.0: See http://wiki.qemu.org/ChangeLog/5.2
  Take note that ongoing feature deprecation is tracked at both
  http://wiki.qemu-project.org/Features/LegacyRemoval and in
  the deprecated.html file installed with the qemu package
  Some noteworthy changes:
* Dropped system emulators: qemu-system-lm32, qemu-system-unicore32
* Dropped linux user emulator: qemu-ppc64abi32
* Added linux user emulator: qemu-extensaeb
* Unicore32 and lm32 guest support dropped
* New sub-packages (most due to ongoing modularization of QEMU):
  qemu-audio-spice, qemu-hw-chardev-spice, qemu-hw-display-virtio-vga, 
  qemu-hw-display-virtio-gpu, qemu-hw-display-virtio-gpu-pci,
  qemu-ui-spice-core, qemu-ui-opengl, qemu-ivshmem-tools
* x86: A new KVM feature which improves the handling of asynchronous page
  faults is available with -cpu ...,kvm-async-pf-int (requires Linux 5.8)
* s390: More instructions emulated under TCG
* PowerPC: nvdimm= machine option now functions correctly; misc improvements
* ARM: new boards: mps2-an386 (Cortex-M4 based) and mps2-an500
  (Cortex-M7 based),  raspi3ap (the Pi 3 model A+), raspi0 (the Pi Zero)
  and raspi1ap (the Pi A+)
* RISC-V: OpenSBI v0.8 included by default; Generic OpenSBI platform used
  when no -bios argument is supplied; Support for NUMA sockets on Virt
  and Spike Machines; Support for migrating machines; misc improvements
* Misc NVMe improvements
* The 'vhost-user-blk' export type has been added, allowing
  qemu-storage-daemon to act as a vhost-user-blk device backend
* The SMBIOS OEM strings can now come from a file
* 9pfs - misc performance related improvements
* virtiofs - misc improvements
* migration: The default migration bandwidth has been increased to 1Gbps
  (users are still encouraged to tune it to their own hardware); The new
  'calc-dirty-rate' and 'query-dirty-rate' QMP commands can help determine
  the likelihood of precopy migration success; TLS+multifd now supported
  for higher bandwidth encrypted migration; misc minor features added
* Misc minor block features added
* Misc doc improvements
* qemu-microvm subpackage change: the bios-microvm.bin is now SeaBIOS based,
  and the qboot based on is now qboot.rom
* elf2dmp is no longer part of qemu-tools (it was never intended to be
  a packaged binary)
* Some subpackages which were 'Requires' are now 'Recommends', allowing for
  a smaller qemu packaging footprint if needed
* Patches dropped (included in release tarball, unless otherwise noted):

- In spec file, where reasonable, switch BuildRequires: XXX-devel
  to be pkgconfig(XXX') instead
- No longer disable link time optimization for qemu for x86. It looks like
  either the build service, qemu code changes and/or the switch to meson
  have resolved issues previously seen there. We still see problems for
  other architectures however.
- For the record, the following issues reported for SUSE SLE15-SP2
  are either fixed in this current package, or are otherwise no longer
  an issue: bsc#1172384 bsc#1174386 bsc#1174641 bsc#1174863 bsc#1175370
  bsc#1175441 bsc#1176494 CVE-2020-13361 CVE-2020-14364 CVE-2020-15863
  CVE-2020-16092 CVE-2020-24352
  and the following feature requests are satisfied by this package:
  jsc#SLE-13689 jsc#SEL-13780 jsc#SLE-13840
- To be more accurate, and to align with other qemu packaging
  practices, rename the qemu-s390 package to qemu-s390x. The old
  name (in the rpm namespace) is provided with a "Provides"
  directive, and an "Obsoletes" done against that name for prior
  qemu versions, as is standard practice (boo#1177764 jsc#SLE-17060)
- Take this opportunity to remove some ancient Split-Provides
  mechanisms which can't conceivably be needed any more:
  qemu-block-curl provided: qemu:%_libdir/%name/block-curl.so
  qemu-guest-agent provided: qemu:%_bindir/qemu-ga
  qemu-tools provided: qemu:%_libexecdir/qemu-bridge-helper
- Disable linux-user 'ls' test on 32 bit arm. It's failing with
  "Allocating guest commpage: Cannot allocate memory" error, which
  we should hunt down, but for now we don't want it to prevent the
  package from being built

Subject: PPC: KVM: Disable mmu notifier check
When using hugetlbfs (which is required for HV mode KVM on 970), we
check for MMU notifiers that on 970 can not be implemented properly.
So disable the check for mmu notifiers on PowerPC guests, making
KVM guests work there, even if possibly racy in some odd circumstances.
