All of them work now. But more job should be done to polish the patches. And the main part of Function Level Reset would be picked by linux-pci. Another thing is we would send out/update above patches before Sept. 28, and hope they can picked by 2.6.28 merge window. Avi, what's your opinion? Of course we would work hard. :) But what's the deadline of merge window? > (Above tasks are working in process, some patches have been sent out, > others will be sent out in near future) - architecture independent (such as > x86, IPF) > - Shared Interrupt support I still don't know who would do this. It's very important for VT-d real usable. If nobody interested in it, I would pick it up, but after Oct. 6 (after National Holiday in China). -- regards Yang, Sheng > - Add dummy driver to hide/unbind passthrough device from host > kernel > > If I omit some good features or you have some good proposals, please feel > free to add them to this list.
