In Ironlake time, we've seen interrupt stall issue with user interrupt, and be warned user interrupt is deprecated, so we moved on to use pipe control notify, although there's a workaround later covered that's required on Ironlake. But it's stable finally. And for sandybridge, there's no such workaround needed. btw, could you also send mails for changes on -next? It'll be easy to be notified. </pre> </blockquote> </body> </html>
