Hi,
I just can't understand what is happening.
The above code on my driver initialization gives the following results.
start_time = rtdm_clock_read();
rtdm_task_busy_sleep(43000);
temp_time = rtdm_clock_read();
rtdm_printk(KERN_INFO "%u - %u = %u\n",(unsigned int) temp_time,
(unsigned
int) start_time, (unsigned int) (temp_time-start_time));
rtdm_printk(KERN_INFO "%u - %u = %u\n",(unsigned int)
(temp_time&0xffffffff), (unsigned int) start_time&0xffffffff, (unsigned int)
((temp_time-start_time)&0xffffffff));
As I expected, both printk gave the same (wrong?) result:
3175950208 - 2800623168 = 375327040
I was waiting something near to 43000, shouldn't I?
Please, can someone explain me what is going on...
Thanks,
Rodrigo.
