I'm having a real hard time understanding why you want to review the code outside the gpu_compute directory. Beyond adding the gpu_compute files, this patch only modifies Ruby code other than the top level SConstruct file that you have already commented on. There are no changes to "common infrastructure" in this patch. Those changes were in our other patches that you have already meticulously reviewed. Also to my understanding, no one at ARM uses Ruby. Similarly, most of us at AMD rarely use the Classic memory system and thus *often* allow ARM changes to those files without reviews from AMD. We understand that you will benefit tremendously by getting your code checked (rather than maintaining it internally) and there is little cost to us, since we do not use the Classic model. We were expecting you would reciprocate that policy. Furthermore, this patch has been on reviewboard for 11 weeks. We've worked hard conforming to all of the comments so far. I cannot justify any more work on these current set of patches. - Brad ----------------------------------------------------------- This is an automatically generated e-mail.
