Many Thanks Jan,
I started investigating code changes. I'm thinking of ...
- adding a new field to the HPETState structure.
uint32_t driftfix;
- adding the property 'driftfix' to the DeviceInfo structure.
DEFINE_PROP_BIT("driftfix", HPETState, driftfix, 0, false)
Using a single bit so that the option syntax would be, e.g.:
-global hpet.driftfix=on (Default is 'off')
- Replace all 'if (hpet_driftfix ...)' by:
if ((HPETState)s->driftfix ...)
Regards,
Uli
