Dear Jan,
--> Would be nice to see it inside drivers/, and to have the required
changes to the build system done as well - when time permits. Then generate
a true patch from your changes (just like here [1]) and repost.
I have managed to create Makefile for my driver in the RTnet tree and build
successfully in rtnet/driver/at91/ directory but not in the rtnet/
directory. Could you help on this?
The printk statements in the do_request_cal_job are as follow:
static struct tdma_job *do_request_cal_job(struct tdma_priv *tdma, struct
tdma_request_cal *job, rtdm_lockctx_t lockctx)
{
struct rt_proc_call *call;
struct tdma_job *prev_job;
int err;
printk("[Debug] callibration start 1\n");
if ((job->period != 1) &&
(tdma->current_cycle % job->period != job->phasing))
return &job->head;
printk("[Debug] callibration start 2\n");
/* remove job until we get a reply */
__list_del(job->head.entry.prev, job->head.entry.next);
job->head.ref_count--;
prev_job = tdma->current_job =
list_entry(job->head.entry.prev, struct tdma_job, entry);
prev_job->ref_count++;
tdma->job_list_revision++;
printk("[Debug] callibration start 3\n");
rtdm_lock_put_irqrestore(&tdma->lock, lockctx);
printk("[Debug] callibration start 4 [delay] %lld\n",
tdma->current_cycle_start + job->offset);
rtdm_task_sleep_until(tdma->current_cycle_start + job->offset);
printk("[Debug] callibration start 5\n");
err = tdma_xmit_request_cal_frame(tdma,
tdma->current_cycle + job->period, job->offset);
rtdm_lock_get_irqsave(&tdma->lock, lockctx);
printk("delay: %lld\n", tdma->current_cycle_start + job->offset -
rtdm_clock_read());
/* terminate call on error */
if (err < 0) {
call = tdma->calibration_call;
tdma->calibration_call = NULL;
if (call) {
rtdm_lock_put_irqrestore(&tdma->lock, lockctx);
rtpc_complete_call(call, err);
rtdm_lock_get_irqsave(&tdma->lock, lockctx);
}
}
return prev_job;
}
Result of Kernel Message:
[Debug] Req Cal Stage
[Debug] callibration start 1
[Debug] callibration start 2
[Debug] callibration start 3
[Debug] callibration start 4 [delay] 1189571585923819617
RTcfg: rtcfg_do_main_event() rtdev=1, event=RTCFG_FRM_STAGE_1_CFG,
state=RTCFG_MAIN_CLIENT_1
Is this because of the delay is too long? Any ideas?
Please advice. Thanks
Regards,
Chun Yeow
