Function Documentation

int acpi_get_hp_hw_control_from_firmware	(	struct pci_dev *	pdev,
		u32	flags
	)

acpi_get_hp_hw_control_from_firmware : the pci_dev of the bridge that has a hotplug controller : requested control bits for _OSC

Attempt to take hotplug control from firmware.

Definition at line 335 of file acpi_pcihp.c.

int acpi_pci_check_ejectable	(	struct pci_bus *	pbus,
		acpi_handle	handle
	)

acpi_pcihp_check_ejectable - check if handle is ejectable ACPI PCI slot : the PCI bus of the PCI slot corresponding to 'handle' : ACPI handle to check

Return 1 if handle is ejectable PCI slot, 0 otherwise.

Definition at line 435 of file acpi_pcihp.c.

int acpi_pci_detect_ejectable

(

acpi_handle

handle

)

acpi_pci_detect_ejectable - check if the PCI bus has ejectable slots - handle of the PCI bus to scan

Returns 1 if the PCI bus has ACPI based ejectable slots, 0 otherwise.
