Detailed Description

Functions and ioctls to manage PCI memory.

Warning

These interfaces aren't stable yet.

Todo:

Implement the remaining ioctl's for the PCI pools.

The wrappers here are so thin that they would be better off inlined..

Function Documentation

void __drm_pci_free	(	struct drm_device *	dev,
		drm_dma_handle_t *	dmah
	)

Free a PCI consistent memory block without freeing its descriptor.

This function is for internal use in the Linux-specific DRM core code.

Definition at line 98 of file drm_pci.c.

drm_dma_handle_t* drm_pci_alloc	(	struct drm_device *	dev,
		size_t	size,
		size_t	align
	)

Allocate a PCI consistent memory block, for DMA.

Definition at line 52 of file drm_pci.c.

void drm_pci_exit	(	struct drm_driver *	driver,
		struct pci_driver *	pdriver
	)

Definition at line 454 of file drm_pci.c.

void drm_pci_free	(	struct drm_device *	dev,
		drm_dma_handle_t *	dmah
	)

Free a PCI consistent memory block.

Definition at line 120 of file drm_pci.c.

int drm_pci_init	(	struct drm_driver *	driver,
		struct pci_driver *	pdriver
	)
