PCI/ACPI: Report ASPM support to BIOS if not disabled from command line

2011-03-21T16:38:02+00:00

We need to distinguish the situation in which ASPM support is
disabled from the command line or through .config from the situation
in which it is disabled, because the hardware or BIOS can't handle
it.  In the former case we should not report ASPM support to the BIOS
through ACPI _OSC, but in the latter case we should do that.

Introduce pcie_aspm_support_enabled() that can be used by
acpi_pci_root_add() to determine whether or not it should report ASPM
support to the BIOS through _OSC.

PCI: fix tlan build when CONFIG_PCI is not enabled

2011-02-16T19:46:09+00:00

When CONFIG_PCI is not enabled, tlan.c has a build error:
drivers/net/tlan.c:503: error: implicit declaration of function 'pci_wake_from_d3'

so add an inline function stub for this function to pci.h when
PCI is not enabled, similar to other stubbed PCI functions.

PCI/PM: Use pm_wakeup_event() directly for reporting wakeup events

2011-01-14T16:55:43+00:00

After recent changes related to wakeup events pm_wakeup_event()
automatically checks if the given device is configured to signal wakeup,
so pci_wakeup_event() may be a static inline function calling
pm_wakeup_event() directly.

PCI/ACPI: Request _OSC control once for each root bridge (v3)

2011-01-14T16:55:41+00:00

Move the evaluation of acpi_pci_osc_control_set() (to request control of
PCI Express native features) into acpi_pci_root_add() to avoid calling
it many times for the same root complex with the same arguments.
Additionally, check if all of the requisite _OSC support bits are set
before calling acpi_pci_osc_control_set() for a given root complex.

PCI: make pci_restore_state return void

2010-12-23T20:53:09+00:00

pci_restore_state only ever returns 0, thus there is no benefit in
having it return any value.  Also, a large majority of the callers do
not check the return code of pci_restore_state.  Make the
pci_restore_state a void return and avoid the overhead.
