Hi Folks,
Sorry for top posting from bed. The mainstream servers will all likely do PCIe but there are several that may not. They should not be excluded. That
said,
if we booted a previously built kernel on a system without an MCFG and got no ECAM/root then things would probably still work.
I think it'll work out either way but for the record there is no requirement to do PCIe on ARM servers that conform to spec.
OK, Catalin already said that was not the main point of the comments for this patch, I think the title and change log of the patch is inconsistent with the code makes Catalin confused, I will update them in next version.
Well what we are talking about is the presence of CONFIG_PCI=y which even in Jons case will be true as he wants to run the same kernel on both sets of hardware.
Now the architecture has PCI support I think its safe to remove the make PCI optional part of the patch as this should be handled runtime not compile time.
I missed that part, must be something wrong work in Sunday :) I will update the patch with ACPI depends on PCI, which makes thing much simpler.
Thanks Hanjun
