From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jeremy Fitzhardinge Subject: [PATCH RFC 0/7] proposed updates to boot protocol and paravirt booting Date: Wed, 06 Jun 2007 15:58:37 -0700 Message-ID: <20070606225837.654272428@goop.org> Return-path: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: virtualization-bounces@lists.linux-foundation.org Errors-To: virtualization-bounces@lists.linux-foundation.org To: "Eric W. Biederman" , "H. Peter Anvin" Cc: lkml , Vivek Goyal , v12n List-Id: virtualization@lists.linuxfoundation.org This series: 1. Updates the boot protocol to version 2.07 2. Clean up the existing build process, to get rid of tools/build and make the linker do more heavy lifting 3. Make the bzImage payload an ELF file. The bootloader can extract this as a naked ELF file by skipping over boot_params.setup_sects worth of 16-bit setup code. 4. Update the boot_params to 2.07, and update the kernel's head.S to jump to the appropriate subarch-specific kernel entrypoint. The very earliest code is common (copy boot_params, clear bss); the split happens just before the initial pagetable setup. + random little changes to make it all hang together This boots native for me, so everything basically works. But I haven't tested it end-to-end yet, because I haven't done the Xen bits yet. Perhaps Rusty can do the lguest version to verify that its all sound in principle (hint hint ;). So, how does it look?
