--- Comment #8 from François Gouget <fgouget at codeweavers.com> ---
Final notes from my TestBot timeline:
* Configuring a QEMU VM to have 'two logical CPUs' results in a dual processor
machine by default. However regular versions of Windows (i.e. non-Pro /
Enterprise) are restricted to only use a single CPU. They will start on
multi-processor machines but make use of only one. This is not an issue for
our Windows 7 VMs as Pro and Ultimate versions can use up to two processor.
But our Windows 8 and 10 VMs use regular editions. So they need QEMU to be
configured with a single multi-core processor instead to properly test
'SMP' configurations.
* On Windows 8+ the SpinCount value of the RtlInitializeCriticalSectionEx()
tests in ntdll:rtl is different on a multi-core or hyperthreaded CPU than
on a single single-core non-hyperthreaded one. On Window s7 SpinCount is 0
no matter what the processor configuration: multi-processor, multi-core or
hyperthreading. So this is a Windows 8+ thing. On Windows 8 SpinCount may
also take non-zero values on systems with multiple single-core
non-hyperthreaded processors but we cannot test that configuration.
* I changed wtbw8 to use a single dual-core processor. wtbwvista, wtbw864 and
wtbw1064 will need similar changes.
