that is right with the multicast event we can pack data too.

correct, at present that is the usecase xe driver has and atleast for
the error part I believe is generic if not we can make it, the framework
is extensible. The idea I had was generic commands which every driver
can use will be part of drm framework and if there are specific commands
or attributes that shall be part of driver. But some thought is needed
here as MAX attributes is needed by userspace and how to define
attribute policy etc..,

your suggestion sounds good and interesting but it might need some
analysis like if we move the registration parts to drm framework how
would we register the driver private commands and attributes if there
are any. But ya having most of the part at drm level helps all the
driver. I'll do some analysis and i'll come back on this.
Thanks,
Aravind.
