gpu: nvgpu: post dbg session event from os specific code
As part of debug session unification following changes are
required.
-Including bug.h header file to fix the compilation issue
on QNX
- The mechanism of posting debug events is OS specific. In Linux
this works through poll fd, wherein we can make use of nvgpu_cond
variables to poll and trigger the corresponding wait_queue
via nvgpu_cond_broadcast_interruptible() call.
The post event functionality on QNX doesn't work on poll though.
It uses iofunc_notify_trigger to post the debug events to calling
process. As such QNX can't work with nvgpu_cond's.
To overcome this issue, it is proposed to create a OS specific
interface for posting debugger events. Linux can call
nvgpu_cond_broadcast_interruptible() in its implementation, which
makes sense since these are already initialized and poll'ed in the
Linux specific code only.
QNX can implement this interface to call iofunc_notify_* functions,
as per its need
