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.

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):

* Patches added:

Makefile-Don-t-check-pc-bios-as-pre-requ.patch
roms-Makefile-add-cross-file-to-qboot-me.patch
qboot-add-cross.ini-file-to-handle-aarch.patch
usb-Help-compiler-out-to-avoid-a-warning.patch
- 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
