      vgaarb: Drop obsolete #ifndef · ce6eacb0
      Bruno Prémont 提交于
      Commit 20cde694 ("x86, ia64: Move EFI_FB vga_default_device()
      initialization to pci_vga_fixup()") moved boot video device detection from
      efifb to x86 and ia64 pci/fixup.c.
      
      Remove the left-over #ifndef check that will always match since the
      corresponding arch-specific define is gone with above patch.

      vgaarb: Don't default exclusively to first video device with mem+io · 86fd887b
      Bruno Prémont 提交于
      Commit 20cde694 ("x86, ia64: Move EFI_FB vga_default_device()
      initialization to pci_vga_fixup()") moved boot video device detection from
      efifb to x86 and ia64 pci/fixup.c.
      
      For dual-GPU Apple computers above change represents a regression as code
      in efifb did forcefully override vga_default_device while the merge did not
      (vgaarb happens prior to PCI fixup).
      
      To improve on initial device selection by vgaarb (it cannot know if PCI
      device not behind bridges see/decode legacy VGA I/O or not), move the
      screen_info based check from pci_video_fixup() to vgaarb's init function and
      use it to refine/override decision taken while adding the individual PCI
      VGA devices.  This way PCI fixup has no reason to adjust vga_default_device
      anymore but can depend on its value for flagging shadowed VBIOS.
      
      This has the nice benefit of removing duplicated code but does introduce a
      #if defined() block in vgaarb.  Not all architectures have screen_info and
      would cause compile to fail without it.

      PCI: Add pci_ignore_hotplug() to ignore hotplug events for a device · b440bde7
      Bjorn Helgaas 提交于
      Powering off a hot-pluggable device, e.g., with pci_set_power_state(D3cold),
      normally generates a hot-remove event that unbinds the driver.
      
      Some drivers expect to remain bound to a device even while they power it
      off and back on again.  This can be dangerous, because if the device is
      removed or replaced while it is powered off, the driver doesn't know that
      anything changed.  But some drivers accept that risk.
      
      Add pci_ignore_hotplug() for use by drivers that know their device cannot
      be removed.  Using pci_ignore_hotplug() tells the PCI core that hot-plug
      events for the device should be ignored.
      
      The radeon and nouveau drivers use this to switch between a low-power,
      integrated GPU and a higher-power, higher-performance discrete GPU.  They
      power off the unused GPU, but they want to remain bound to it.
      
      This is a reimplementation of f244d8b6 ("ACPIPHP / radeon / nouveau:
      Fix VGA switcheroo problem related to hotplug") but extends it to work with
      both acpiphp and pciehp.
      
      This fixes a problem where systems with dual GPUs using the radeon drivers
      become unusable, freezing every few seconds (see bugzillas below).  The
      resume of the radeon device may also fail, e.g.,
      
      This fixes problems on dual GPU systems where the radeon driver becomes
      unusable because of problems while suspending the device, as in bug 79701:

      Pull fix for ftrace function tracer/profiler conflict from Steven Rostedt:
       "The rewrite of the ftrace code that makes it possible to allow for
        separate trampolines had a design flaw with the interaction between
        the function and function_graph tracers.
      
        The main flaw was the simplification of the use of multiple tracers
        having the same filter (like function and function_graph, that use the
        set_ftrace_filter file to filter their code).  The design assumed that
        the two tracers could never run simultaneously as only one tracer can
        be used at a time.  The problem with this assumption was that the
        function profiler could be implemented on top of the function graph
        tracer, and the function profiler could run at the same time as the
        function tracer.  This caused the assumption to be broken and when
        ftrace detected this failed assumpiton it would spit out a nasty
        warning and shut itself down.
      
        Instead of using a single ftrace_ops that switches between the
        function and function_graph callbacks, the two tracers can again use
        their own ftrace_ops.  But instead of having a complex hierarchy of
        ftrace_ops, the filter fields are placed in its own structure and the
        ftrace_ops can carefully use the same filter.  This change took a bit
        to be able to allow for this and currently only the global_ops can
        share the same filter, but this new design can easily be modified to
        allow for any ftrace_ops to share its filter with another ftrace_ops.
      
        The first four patches deal with the change of allowing the ftrace_ops
        to share the filter (and this needs to go to 3.16 as well).
      
        The fifth patch fixes a bug that was also caused by the new changes
        but only for archs other than x86, and only if those archs implement a
        direct call to the function_graph tracer which they do not do yet but
        will in the future.  It does not need to go to stable, but needs to be
        fixed before the other archs update their code to allow direct calls
        to the function_graph trampoline"

      aio: fix reqs_available handling · d856f32a
      Benjamin LaHaise 提交于
      As reported by Dan Aloni, commit f8567a38 ("aio: fix aio request
      leak when events are reaped by userspace") introduces a regression when
      user code attempts to perform io_submit() with more events than are
      available in the ring buffer.  Reverting that commit would reintroduce a
      regression when user space event reaping is used.
      
      Fixing this bug is a bit more involved than the previous attempts to fix
      this regression.  Since we do not have a single point at which we can
      count events as being reaped by user space and io_getevents(), we have
      to track event completion by looking at the number of events left in the
      event ring.  So long as there are as many events in the ring buffer as
      there have been completion events generate, we cannot call
      put_reqs_available().  The code to check for this is now placed in
      refill_reqs_available().
      
      A test program from Dan and modified by me for verifying this bug is available
      at http://www.kvack.org/~bcrl/20140824-aio_bug.c .

      ARM: tegra: apalis/colibri t30: fix on-module 5v0 supplies · caa9eac5
      Marcel Ziswiler 提交于
      Working on Gigabit/PCIe support in U-Boot for Apalis T30 I realised
      that the current device tree source includes for our modules only
      happen to work due to referencing the on-carrier 5v0 supply from USB
      which is not at all available on-module. The modules actually contain
      TPS60150 charge pumps to generate the PMIC required 5 volts from the
      one and only 3.3 volt module supply. This patch fixes this.
      
      (Note: When back-porting this to v3.16 stable releases, simply drop the
      change to tegra30-apalis.dtsi; that file was added in v3.17)
