If you take svn head and run it on SimNOW, you'll get reports that
registers
values were stored:
PCI: 00:18.0 1c0 <- ... amdk8_set_resource
But the value never changes.
Check how the access are being done. cf8/cfc should always work but MMIO will require proper routing.
Thanks. I am always using cf8/cfc, but I'm calling different functions. I've never understood all the different functions: pci_write_config32 pci_conf1_write_config32 etc.
I know that pci_write_config32 tries to find the correct pci_ops to use, pci_conf1_write_config32 tries to do it directly, but I don't know why one would work and not the other. V3 only has one pci bus ops struct defined.
Thanks, Myles
