Function Documentation

void destroy_cis_cache

(

struct pcmcia_socket *

s

)

destroy_cis_cache() - destroy the CIS cache : pcmcia_socket for which CIS cache shall be destroyed

This destroys the CIS cache but keeps any fake CIS alive. Must be called with ops_mutex held.

int pccard_validate_cis	(	struct pcmcia_socket *	s,
		unsigned int *	info
	)

pccard_validate_cis() - check whether card has a sensible CIS : the struct pcmcia_socket we are to check : returns the number of tuples in the (valid) CIS, or 0

This tries to determine if a card has a sensible CIS. In , it returns the number of tuples in the CIS, or 0 if the CIS looks bad. The checks include making sure several critical tuples are present and valid; seeing if the total number of tuples is reasonable; and looking for tuples that use reserved codes.

The function returns 0 on success.

pcmcia_read_cis_mem() - low-level function to read CIS memory

must be called with ops_mutex held

Definition at line 136 of file cistpl.c.

int pcmcia_replace_cis	(	struct pcmcia_socket *	s,
		const u8 *	data,
		const size_t	len
	)

pcmcia_replace_cis() - use a replacement CIS instead of the card's CIS

For really bad cards, we provide a facility for uploading a replacement CIS.

pcmcia_write_cis_mem() - low-level function to write CIS memory

Probably only useful for writing one-byte registers. Must be called with ops_mutex held.
