Title: RE: [LinuxBIOS] Re: topics for linuxbios summit
Eric,
It seems that cpu_path and cpu_bus_path in
include/device/path.h are not used.
So what do you prefer
struct apic_path
{
unsigned
apic_id;
unsigned
node id;
unsigned
core_id;
}
Or
struct cpu_path
{
unsigned
id;
unsigned
apic_id;
unsigned
node_id;
unsigned
core_id;
}

Stepan: No, the information has to be reorganized. Currently pirq and mptables
Stepan: have to be hand crafted, and this is the complicated thing. Instead the
Stepan: abstract information should be put to the configuration filess, if it
Stepan: can not be probed.
YH: I suggest to add
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.
2. for apci_cluster_id, will add two fields core_id and node_id, ( instantiate
it when cpu_init)...
3. pci device: add pci_irq_routing, and pci_possiable_resource ( for apci _PRT
and _PRS...)
how about ioapci in the internal tree?
