There are two rt_alarm_create functions. One is for the kernel space and
the other is for user space.
I have a linux driver that has an interrupt service routine. When the
driver is loaded using insmod, it executes the rt_alarm_create. When the
interrupt is triggered, the interrupt service routine executes the
rt_alarm_start function. When the rt_alarm_start function expires, it
executes the alarm handler code. All this code is executed in kernel space.
What I would like to do is create a user application that executes the alarm
handler code rather than the linux driver in kernel space. If the
rt_alarm_create is executed in kernel space, is there a way to pass the
alarm descriptor to user space?
Wayne
