Detailed Description

internal functions for the vspace library

Function Documentation

errval_t vspace_add_vregion	(	struct vspace *	vspace,
		struct vregion *	region
	)

Add a new region into the vspace.

Parameters

point	The vspace struct
region	The region to add

pmap implementation rely on vspace maintaining an ordered list of vregions

errval_t vspace_pinned_alloc	(	void **	retbuf,
		enum slab_type slab_type
	)

Allocate some slabs.

Parameters

retbuf	Pointer to return the allocated memory
slab_type	Type of slab the memory is allocated for

Since this region is used for backing specific slabs, only those types of slabs can be allocated.

errval_t vspace_pinned_init

(

void

)

Initialize the pinned region.

Allocates a region of virtual address space and initializes its state.

errval_t vspace_remove_vregion	(	struct vspace *	vspace,
		struct vregion *	region
	)

remove a region from the vspace

Parameters

point	The vspace struct
region	The region to remove
