Hi all,
I would like to modify the adapter driver interfaces to allow per-instance
driver variable structures.
This would:
* Get rid of loads of static and global variables.
* Allow multiple interfaces
The proposed prototypes below mostly add this per-instance variable as an
instance handle.
Drivers could keep using the current system and be modified when suitable to
use the per -instance parameters.
Is this something that is wanted?
Do you have any thoughts on the proposed organisation below?
Thanks,
Evan
Proposed interface driver prototypes:
{
char *name;
const char **transports;
const struct swd_driver *swd;
const struct command_registration *commands;
int (*create)(Jim_GetOptInfo *options, int interface_num,
adapter_handle_t *new_handle);
int (*destroy)(adapter_handle_t handle);
int (*init)(adapter_handle_t handle);
int (*quit)(adapter_handle_t handle);
int (*speed)(adapter_handle_t handle, int speed);
int (*power_dropout)(adapter_handle_t handle, int
*power_dropout);
int (*srst_asserted)(adapter_handle_t handle, int
*srst_asserted);
/* JTAG functions - to be split out into separate structure
soon */
int (*execute_queue)(adapter_handle_t handle, struct
jtag_command *cmd_queue);
int (*khz)(adapter_handle_t handle, int khz, int *jtag_speed);
int (*speed_div)(adapter_handle_t handle, int speed, int *khz);
};
