Re: Missing features in QEMU SapphireRapid definition

[Wang, Lei]

Hi Manish,

Thanks for the information. It seems those 3 features are missing in the SPR CPU
Model definition, we are currently polishing our new SPR CPU Model version, you
can launch the SPR CPU Model using:

        -cpu SapphireRapids,+cldemote,+movdiri,+movdir64b

as a workaround and sorry for the inconvenience:)

Thanks,
Lei
