Hi,
Another neanderthal approach to add multi-arch acceptance tests using
Avocado.
Since Cleber Rosa work got merged [0], I can restart my previous attempt [1]
at using Avocado in QEMU.
Cleber Rosa rewrote my previous v1 [1], in good python, now this v2 pushes
a bit further:

This adds ability to expose some host CPU power management capabilities
to guests. For intel guests, this is sufficient for guest to enable low
power CPU states on idle. For AMD guests it isn't sufficient, deeper
C-states are entered using System-IO.
When enabled this puts CPU in a low power state
With this flag, kvm allows guest to control host CPU power state. This
increases latency for other processes using same host CPU in an
unpredictable way, but if decreases idle entry/exit times for the
running VCPU, so to use it QEMU needs a hint about whether host CPU is
overcommitted, hence the f
When guest CPU PM is enabled, and with -cpu host, expose the host CPU
MWAIT leaf in the CPUID so guest can make good PM decisions.
Note: the result is 100% CPU utilization reported by host as host

The timer controller can be driven by either an external 1MHz clock or
by the APB clock. Today, the model makes this assumption that the APB
frequency is 24MHz but this is incorrect on the AST2400 SoC. palmetto
machines use a 48MHz input clock source.
Use the SCU object to get the APB frequency an

When the AioContext changes, we need to associate a LinuxAioState with
the new AioContext. Use the bdrv_attach_aio_context callback and call
the new aio_setup_linux_aio(), which will allocate a new AioContext if
needed, and return errors on failures. If it fails for any reason,

Hi Justin,
We are trying to use QEMU on Windows Hyper-V environment with whpx enabled
for better performance. We were unable to build QEMU with WHPX support. We
used Ubuntu 18.04 server VM with two libraries (WinHv*.lib) from the latest
Windows 10 SDK to build QEMU and added '--enable-whpx' para

Sure. I guess persistent bitmaps that exist when BDRV_O_INACTIVE is set

Per DPIOO1, does this go to false for the first DRQ block, or did I
misunderstand? Currently my understanding:
- device->host
DPIOI1
Interrupt bit shall be set.
- host-
Hmm... Is this a stack size protection fault due to the hardening?
We tried to fix the ATAPI recursion depth issue recently, but caused a
regression that stops us from booting with SeaBIOS (maybe UEFI too?) and
patches are pending to fix this, so sit tight and I'll have a git commit
for you to try
