Function Documentation

void radeon_acpi_fini

(

struct radeon_device *

rdev

)

radeon_acpi_fini - tear down driver acpi support

: radeon_device pointer

Unregisters with the acpi notifier chain (all asics).

Definition at line 646 of file radeon_acpi.c.

int radeon_acpi_init

(

struct radeon_device *

rdev

)

radeon_acpi_init - init driver acpi support

: radeon_device pointer

Verifies the AMD ACPI interfaces and registers with the acpi notifier chain (all asics). Returns 0 on success, error on failure.

Definition at line 549 of file radeon_acpi.c.

int radeon_atif_handler	(	struct radeon_device *	rdev,
		struct acpi_bus_event *	event
	)

radeon_atif_handler - handle ATIF notify requests

: radeon_device pointer : atif sbios request struct

Checks the acpi event and if it matches an atif event, handles it. Returns NOTIFY code
