Linux Device Driver: how can an ISR wake up a user-thread?

Hi all, Is it possible to do the following in Linux (kernel 2.6.x): - A user-space thread goes to "sleep". Using any call/mechanism - On a hardware generated interrupt, the Interrupt handler (ISR) "wakes" the sleeping user-thread. I have seen wait_event() and wake_up() but it appears...

NAME

       thread - General: Contains kernel threads-related information

SYNOPSIS

       ----------------------------
       Member Name   Data Type
       ----------------------------
       wait_result   kern_return_t
       ----------------------------

MEMBERS

       Specifies  the  outcome	of  the  wait. The kernel can set this member to one of the following values: THREAD_AWAKENED, THREAD_INTERRUPTED,
       THREAD_TIMED_OUT, THREAD_SHOULD_TERMINATE, and THREAD_RESTART.

DESCRIPTION

       The thread data structure contains kernel threads-related information. Kernel modules typically use the wait_result member (with  the  cur-
       rent_thread  routine)  to  check for the result of the wait. The values associated with the wait_result member have the following meanings:
       The result of the assert wait is a normal wakeup.  The wait condition was interrupted by the clear_wait routine.  The specified timeout has
       expired.  The result of the assert wait is that the current kernel thread should terminate.  The current kernel thread should be restarted.

NOTES

       The  header  file <thread.h> shows a typedef statement that assigns the alternate name thread_t for a pointer to the thread data structure.
       Many of the kernel threads-related routines operate on these pointers to thread data structures.

       The thread data structure is an opaque data structure; that is, all of its associated members (except for the wait_result member) are  ref-
       erenced and manipulated by the operating system and not by the user of kernel threads.
