Of course, I'm sure you're right. In the thread you cited earlier, Wolfgang Schildbach refers to "ARM System Developer's Guide", by Sloss, Symes, and Wright, Elsevier 2004 as documentation that may be sufficient for Qemu ARMv6 support, and which is not covered by the license. If ARMv6 support were developed by someone else, using only that book, and maybe looking at other code (GCC, Linux etc.), that would prove that all the information used is from other sources not covered by the license, wouldn't it? The support might be missing a few features, if the other information sources are incomplete, but even incomplete support that can be deduced from those sources would be good enough for most purposes. If that were done, you could prove that the resulting feature in Qemu was written using sources not covered by the license. So would you have any problem contributing to Qemu after ARMv6 support was integrated, if the person who contributes ARMv6 support states that they have never seen the ARM document and refers to the sources they have used instead? -- Jamie _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
