I have a question about the combination of RH bit and DM bit of 10.11.1 Message Address Register Format.
I use the combination as below, it looks like work is going well.
RH = 0
DM = 1
But, there are following mentions in 10.11.1, so the combination of RH = 0 and DM = 1 looks like the wrong combination.
>If RH is 0, then the DM bit is ignored and the message is sent ahead
>independent of whether the physical orlogical destination mode is used.
If wrong, which combination should I use?
My system is AMP（Asymmetric Multiprocessing）system, and it needs to send the MSI interrupt to the plural processors without the lowest interrupt priority.
