Hi,
while porting ipipe to 4.5, I am facing the following issue:
clockchips.h has changed, and the set_mode function pointer has been
replaced by
int (*set_state_periodic)(struct clock_event_device *);
int (*set_state_oneshot)(struct clock_event_device *);
int (*set_state_oneshot_stopped)(struct
clock_event_device *);
int (*set_state_shutdown)(struct clock_event_device *);
Moreover, CLOCK_EVT_MODE_XXX have been renamed to :
enum clock_event_state {
CLOCK_EVT_STATE_DETACHED,
CLOCK_EVT_STATE_SHUTDOWN,
CLOCK_EVT_STATE_PERIODIC,
CLOCK_EVT_STATE_ONESHOT,
CLOCK_EVT_STATE_ONESHOT_STOPPED,
};
The impact therefore goes further than ipipe , since xenomai uses a
single pointer
for performing emulation.
I am just wondering what is the best way to deal with this, without
impacting to much code
Is it best to add a compatibility wrapper (moreover, the set_state_xxx
functions are only used in clockevents.c), and some extra #defines
or to spread the changes up to xenomai code ?
Thanks,
Thierry
