Linux kernel source tree

Log bridge secondary/subordinate bus and window information at the same time we log the bridge BARs, just after discovering the bridge and before scanning the bridge's secondary bus. This logs the bridge and downstream devices in a more logical order: - pci 0000:00:01.0: [8086:1901] type 01 class 0x060400 - pci 0000:01:00.0: [10de:13b6] type 00 class 0x030200 - pci 0000:01:00.0: reg 0x10: [mem 0xec000000-0xecffffff] - pci 0000:00:01.0: PCI bridge to [bus 01] - pci 0000:00:01.0: bridge window [io 0xe000-0xefff] + pci 0000:00:01.0: [8086:1901] type 01 class 0x060400 + pci 0000:00:01.0: PCI bridge to [bus 01] + pci 0000:00:01.0: bridge window [io 0xe000-0xefff] + pci 0000:01:00.0: [10de:13b6] type 00 class 0x030200 + pci 0000:01:00.0: reg 0x10: [mem 0xec000000-0xecffffff] Note that we read the windows into a temporary struct resource that is thrown away, not into the resources in the struct pci_bus. The windows may be adjusted after we know what downstream devices require, and those adjustments are logged as they are made. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
