A buddy of mine and I have a project in which we have to implement a PCI Express rootport. However, these window sizes are configurable to expose a wider range of memory through one BAR. Instead of looking this up via lspci on each platform, I wanted to write a bash script to use the vendor/device id's to look up the base address and call the application instead. Every PXI/PCI device must have an associated kernel-level driver. v2: rebased, style cleanups, disable mem decode before resize, handle gmc_v9 as well, round size up to power of two. The nvidia GPUs expose the following areas to the outside world through PCI: PCI configuration space / PCIE extended configuration space; MMIO registers: BAR0 - memory, 0x1000000 bytes or more depending on card type; VRAM aperture: BAR1 - memory, 0x1000000 bytes or more depending on card type [NV3+ only]. lspci is a command on Unix-like operating systems that prints ("lists") detailed information about all PCI buses and devices in the system. 0: BAR0 RAM virt: 0xffffff800b3dc000 Make a note of the "BAR0 RAM phys" address. 071153] bnad_pci_probe : (0xffff88061e4a5000, 0xffffffffc00d10c0) PCI Func : (2) [ 15.
