• 284f5f9db   PCI: work around Stratus ftServer broken PCIe hierarchy ... Browse Code »

  A PCIe downstream port is a P2P bridge. Its secondary interface is
  a link that should lead only to device 0 (unless ARI is enabled)[1], so
  we don't probe for non-zero device numbers.

  Some Stratus ftServer systems have a PCIe downstream port (02:00.0) that
  leads to both an upstream port (03:00.0) and a downstream port (03:01.0),
  and 03:01.0 has important devices below it:

  [0000:02]-+-00.0-[03-3c]--+-00.0-[04-09]--...
  \-01.0-[0a-0d]--+-[USB]
  +-[NIC]
  +-...

  Previously, we didn't enumerate device 03:01.0, so USB and the network
  didn't work. This patch adds a DMI quirk to scan all device numbers,
  not just 0, below a downstream port.

  Based on a patch by Prarit Bhargava.

  Add a pci_clear_flags() for cases when we statically initialize
  pci_flags, then decide to clear things out later.

• f4ffd5e5d   pci: move microblaze and powerpc pci flag functions into asm-generic ... Browse Code »

  Move separate microblaze and powerpc pci flag functions pci_set_flags,
  pci_add_flags, and pci_has_flag into asm-generic/pci-bridge.h so other
  archs can use them.
