to stopping of the timer in certain power states (which
we do not even emulate IIRC). In that case, the OS is under risk of
sleeping forever, thus need to look for a different wakeup source.
HPET will always be the default broadcast event device I think.

Hi,
We just met a problem of QEMU memory allocation.
Here is the description:

This series aggressively refactors the PC machine initialization to be more
modelled and less ad-hoc. The highlights of this series are:
1) Things like -m and -bios-name are now device model properties
2) The i440fx and piix3 are now modelled in a thorough fashion
3) i440fx_init is trivialized
Take advantage of Andreas's pci-host patchset, add instance_init function
to fully implement convert pci-host to QOM.
