For this one, you should be able to get away with --cpu 7-A.security rather than listing a random CPU that happens to implement the required extension. This on the surface minor cleanup makes me unreasonably happy - thanks. So if you can fold that in: Reviewed-by: Leif Lindholm <leif.lindh...@linaro.org> For whatever reason, a --cpu 7-A.virtualization never seems to have been implemented... / Leif _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
