Field Documentation

attr_cleanup

void(* format_ops::attr_cleanup) (struct attr_dict *dict)

Clean up attribute hooks.

Parameters

dict	Attribute dictionary.

get_page

kdump_status(* format_ops::get_page) (struct page_io *pio)

Get page data.

Parameters

pio	Page I/O control.

Note: The requested address space is specified in pio. It is always an address space specified by xlat_caps. Since most file formats specify only one capability, their get_page methods do not have to care.

name

const char* format_ops::name

Format name (identifier).

This is a unique identifier for the dump file format. In other words, there is a 1:1 mapping between this identifier and the access methods for the corresponding dump file.

post_addrxlat

kdump_status(* format_ops::post_addrxlat) (kdump_ctx_t *ctx)

Address translation post-hook.

Parameters

ctx	Dump file object.

Returns

Status code.

This routine is called whenever address translation is (re-)initialized to allow format-specific adjustments to the translation system (e.g. physical<->machine address translation in a Xen DomU dump file).

put_page

void(* format_ops::put_page) (struct page_io *pio)

Drop a reference to a page.

Parameters

pio	Page I/O control.

realloc_caches

kdump_status(* format_ops::realloc_caches) (kdump_ctx_t *ctx)

Reallocate any format-specific caches.

Parameters

ctx	Dump file object.

Returns

Status (KDUMP_OK on success).
