Function Documentation

int __check_region ( struct resource *  parent,
resource_size_t  start,
resource_size_t  n 
)

__check_region - check if a resource region is busy or free : parent resource descriptor : resource start address
: resource region size

Returns 0 if the region is free at the moment it is checked, returns %-EBUSY if the region is busy.

NOTE: This function is deprecated because its use is racy. Even if it returns 0, a subsequent call to request_region() may fail because another driver etc. just allocated the region. Do NOT use it. It will be removed from the kernel.

void __release_region ( struct resource *  parent,

__release_region - release a previously reserved resource region : parent resource descriptor : resource start address
: resource region size

The described resource region must match a currently busy region.

int adjust_resource ( struct resource *  res,
resource_size_t  start,
resource_size_t  size 
)

adjust_resource - modify a resource's start and size : resource to modify : new start value : new size

Given an existing resource, change its start and size to match the arguments. Returns 0 on success, -EBUSY if it can't fit. Existing children of the resource are assumed to be immutable.

resource_size_t  max,
resource_size_t  align,
resource_size_t(*)(void *, const struct resource *, resource_size_t, resource_size_t)  alignf,

)

allocate_resource - allocate empty slot in the resource tree given range & alignment. The resource will be reallocated with a new size if it was already allocated : root resource descriptor : resource descriptor desired by caller : requested resource region size : minimum boundary to allocate : maximum boundary to allocate : alignment requested, in bytes : alignment function, optional, called if not NULL : arbitrary data to pass to the function

int insert_resource ( struct resource *  parent,
struct resource *  new 
)

insert_resource - Inserts a resource in the resource tree : parent of the new resource : new resource to insert

Returns 0 on success, -EBUSY if the resource can't be inserted.

Definition at line 667 of file resource.c.

struct resource* insert_resource_conflict ( struct resource *  parent,
struct resource *  new 
)
read

insert_resource_conflict - Inserts resource in the resource tree : parent of the new resource : new resource to insert

Returns 0 on success, conflict resource if the resource can't be inserted.

This function is equivalent to request_resource_conflict when no conflict happens. If a conflict happens, and the conflicting resources entirely fit within the range of the new resource, then the new resource is inserted and the conflicting resources become children of the new resource.

Definition at line 650 of file resource.c.

void insert_resource_expand_to_fit ( struct resource *  root,
struct resource *  new 
)

insert_resource_expand_to_fit - Insert a resource into the resource tree : root resource descriptor : new resource to insert

Insert a resource into the resource tree, possibly expanding it in order to make it encompass any conflicting resources.
