Hi, I am currently setting up PCIe framework on ARM Cortex A8 based reference board. As I am doing it for the first time, I had couple of queries. The kernel version we have chosen is 2.6.24 1. How should I go for BAR assignment? I have seen that different platforms have different standards to do it. Some do it in bootloaders and very few in Linux. I am inclined to do that in bootloader as I am not going to modify any of the address space in kernel. But still wanted to know if there are implications. If I should do that in Kernel then if you could point to any reference source that would be helpful. 2. I see that 2.6.24 used the port bus driver for initializing the PCIE framework and specifically three different service drivers, virtual channels, aer and hotplug driver while in 2.6.28, there is a separate pcie reference code present for some of the ARM platforms like Marvell's Kirkwood. Which way should I choose? Normal PCI with PBD or 2.6.28 kind of framework and why? 3. I would be configuring the PCIe in RC mode with total five different interrupts supported: a. MSI b. Legacy c. events d. fatal errors e. non-fatal errors Is there any reference where I can look at to start with?
