PCI config space doubt

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Does Linux assign the resources to PCI devices? Or is it done by PCI firmware?

If it is done by firmware, I have the following doubt:

By looking at the PCI configuration space, I can only see Base Address
Registers (BARS) for the 6 resources a device can have. How does the
kernel know about the length and the flags of the resources (since
they do no seem to be present in PCI config space)?

Thanks,

Rajat
