In SDM vol3, 10.11.1, SDM says :
"Redirection hint indication (RH) — When this bit is set, the message is directed to the processor with the lowest interrupt priority among processors that can receive the interrupt."
If I want to send a msi with lowest interrupt priority mode, I just need to set Delivery Mode in MSI data register to 001B, so what's the meaning of the existance of RH in msi address register?
[I had posted this question on https://community.intel.com/t5/Processors/Redundancy-of-quot-Redirection-hint-indication-quot-in-SDM... , and forum manager told me to ask question here. so do not blame me on repost-questioning.]
