Subject: [PATCH] [FEAT VS1804] zipl: Make use of __noreturn macro From: Marc Hartmayer Summary: genprotimg: Introduce new tool for the creation of PV images Description: genprotimg takes a kernel, host-key documents, optionally an initrd, optionally a file with the kernel command line, and it generates a single, loadable image file. The image consists of a concatenation of a plain text boot loader, the encrypted components for kernel, initrd, and cmdline, and the integrity-protected PV header, containing metadata necessary for running the guest in PV mode. It's possible to use this image file as a kernel for zIPL or for a direct kernel boot using QEMU.
