Check V1 for more details: https://lore.kernel.org/lkml/1710265404-23146-1-git-send-email-ssengar@linux.microsoft.com/ But on further review it was observed that x86 DeviceTree config has modified recently, and there is opportunity to improve the existing smp parsing for DeviceTree. https://lore.kernel.org/lkml/20230807135027.064321764@linutronix.de/ Changes are small but I have logically separated them into four patches. I am willing to merge them if there are too many [V2] - Modified the approch how to fix the SMT issue, this is patch 3 in this series. V1 for it is mentioned in above link. - Added 2 more patches which are related to new SMP config parsing. These are patches 2 and 4 in this series. - Fixed an issue with hv_vtl platform how it should use the smp parsing for DeviceTree with a fixes tag.
