Can you elaborate on mechanism #1 for accessing the PCI configuration space?
Hello everyone, the OS developer is in touch (no).
I'm doing PCI work using the #1 PCI configuration space access mechanism.
I understood the basics a little, but not completely.
Can you give as many details as possible and preferably a small example?
PS, don't post a link to osdev.org, I just read it there.

Ok, here's the main thing for you:
-- you write to the first port, to which address in the config space there will be access, after which you write or read the second port. This is the #1 access mechanism on x86.
What do you lack understanding?
