Hi Kees, I tested your patch, it works. The way is like below: I changed kexec-tools to make all add_buffer doing from down to top. Then all stuff including kernel, initrd, setupda, cmdline, realmode_data all are put inside 0~1G. And set E820_MAX to 10, since on my pc there are 17 memoery regions, then 7 memory regions are added into setup_data as a blob. Then copy arch/x86/boot/printf.c to arch/x86/boot/compressed/ and make it work. From printing message, the setup data is checking each time when a memory slot is added. > > Thanks! > > -Kees > > -- > Kees Cook > Chrome OS Security -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
