      PCI: use _CRS for PCI resource allocation · 62f420f8
      Gary Hade authored
      Use _CRS for PCI resource allocation
      
      This patch resolves an issue where incorrect PCI memory and i/o ranges
      are being assigned to hotplugged PCI devices on some IBM systems.  The
      resource mis-allocation not only makes the PCI device unuseable but
      often makes the entire system unuseable due to resulting machine checks.
      
      The hotplug capable PCI slots on the affected systems are not located
      under a standard P2P bridge but are instead located under PCI root
      bridges or subtractive decode P2P bridges.  For example, the IBM x3850
      contains 2 hotplug capable PCI-X slots and 4 hotplug capable PCIe slots
      with the PCI-X slots each located under a PCI root bridge and the PCIe
      slots each located under a subtractive decode P2P bridge.
      
      The current i386/x86_64 PCI resource allocation code does not use _CRS
      returned resource information.  No other resource information source is
      available for slots that are not below a standard P2P bridge so
      incorrect ranges are being allocated from e820 hole causing the bad
      result.
      
      This patch causes the kernel to use _CRS returned resource info.  It is
      roughly based on a change provided by Matthew Wilcox for the ia64 kernel
      in 2005.  Due to possible buggy BIOS factor and possible yet to be
      discovered kernel issues the function is disabled by default and can be
      enabled with pci=use_crs.

      PCI: avoid P2P prefetch window for expansion ROMs · fd64cb46
      Gary Hade authored
      Avoid creating P2P prefetch window for expansion ROMs
      
      Because of the future possibility that P2P prefetch windows will contain
      address ranges above 4GB some BIOSes are providing space in the P2P
      non-prefetch windows for expansion ROMs.  This is due to expansion ROM
      BAR 32-bit limitation.  When expansion ROM BARs without BIOS assigned
      address(es) are currently found behind a P2P bridge, the kernel attempts
      to create a P2P prefetch window for them even though space for them has
      already been provided in the non-prefetch window.  _CRS on some systems
      with certain resource conservation conscious BIOSes may not provide the
      extra 1MB or more memory resource needed for the expansion ROM motivated
      prefetch window causing resource allocation errors.
      
      This change corrects the problem by removing IORESOURCE_PREFETCH from
      the expansion ROM flags initialization.  It also removes
      IORESOURCE_CACHEABLE which seems inappropriate if only non-cacheable
      memory is available.

      Gary Hade authored
      Skip ISA ioresource alignment on some systems
      
      To conserve limited PCI i/o resource on some IBM multi-node systems, the
      BIOS allocates (via _CRS) and expects the kernel to use addresses in
      ranges currently excluded by pcibios_align_resource() [i386/pci/i386.c].
      This change allows the kernel to use the currently excluded address
      ranges on the IBM x3800, x3850, and x3950.

      PCI: remove transparent bridge sizing · 8fa5913d
      Gary Hade authored
      Remove transparent bridge sizing.
      
      Due to code in pci_read_bridge_bases() [drivers/pci/probe.c] the child
      bus of a transparent bridge already has access to the parent bus
      resources so transparent bridge sizing appears unnecessary.  The bridge
      sizing includes alignment and granularity adjustments that can cause
      significantly more memory to be reserved from the parant bus than
      required by devices on the child bus and allotted by _CRS.

      MSI: Use correct data offset for 32-bit MSI in read_msi_msg() · cbf5d9e6
      Roland Dreier authored
      While reading the MSI code trying to find a reason why MSI wouldn't
      work for devices that have a 32-bit MSI address capability, I noticed
      that read_msi_msg() seems to read the message data from the wrong
      offset in this case.

      PCI: Fix incorrect argument order to list_add_tail() in PCI dynamic ID code · a56bc69a
      Michael Ellerman authored
      The code for dynamically assigning new ids to PCI drivers,
      store_new_id(), calls list_add_tail() with the list head and new node
      arguments in reversed order.
      
      The result is that every new id written essentially overwrites the
      previous list of ids.
      
      Caught with the help of Rusty's "horribly bad" list_node patch:

      PCI: Remove no longer correct documentation regarding MSI vector assignment · 4904e23b
      Michael Ellerman authored
      The MSI vector reservation system described in Documentation/MSI-HOWTO.txt
      was removed by Eric in 92db6d10. Remove
      the references to it in the documentation.
      
      While we're here § 5.5.1 refers to x86 hardware requirements, so make that
      clear.

      PCI: re-enable onboard sound on "MSI K8T Neo2-FIR" · 346ca04d
      Johannes Goecke authored
      On the "MSI K8T Neo2-FIR" board the BIOS disables the onboard
      soundcard, if a second PCI soundcard is present.
      
      This patch sets the korrect register bit to enable the onboard sound.
      
      Removed old code in /drivers/pci/quirks.c that only checks for the
      PCI-ID and fires on any Board with VIA 8237.
      
      New code in /arch/i386/pci/fixup.c checks the DMI-tables and only runs
      on the specific board.
