> YH: Good point, But I worry that we make LinuxBIOS more complicated.<br>
<br>
Stepan: No, the information has to be reorganized. Currently pirq and mptables<br>
Stepan: have to be hand crafted, and this is the complicated thing. Instead the<br>
Stepan: abstract information should be put to the configuration filess, if it<br>
Stepan: can not be probed.<br>
<br>
YH: I suggest to add<br>
1. one node id to ram_resource, so the index will be (idx<<8 | nodeid),
So I can re-use ram_resource in pci_domain for SRAT creating.<br>
2. for apci_cluster_id, will add two fields core_id and node_id, ( instantiate
it when cpu_init)...<br>
3. pci device: add pci_irq_routing, and pci_possiable_resource ( for apci _PRT
and _PRS...)<br>
<br>
how about ioapci in the internal tree?<br>
