Function Documentation

◆ edt_kmalloc()

asmlinkage void * edt_kmalloc	(	size_t	size,
		char *	tag
	)

Memory Allocation/deallocation

◆ edt_cache_free_list_count()

unsigned int edt_cache_free_list_count ( void )

Get number of pages in the cache page list.

Pre-allocated cache page pool is setup by edt_cache_create_free_list().

Returns: Total number of pages in the cache list.

◆ edt_mem_map_setup()

asmlinkage int edt_mem_map_setup	(	EdtMemMapping *	map,
		int	bufsize
	)

edt_mem_map_setup Top-level buffer setup, will fill in map with list of pages and the sglist and sglist broken up into chunks Assumes map->pci_dev is set already

◆ edt_mem_map_clear_sg()

asmlinkage int edt_mem_map_clear_sg ( EdtMemMapping * map )

delete the sg array defined in edt_mem_map_setup_sg
