Message-Id: List-Id: References: In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ia64@vger.kernel.org Hi, As Tony pointed out, elilo was changed a very long time ago, to ONLY use the *physical address* (paddr) found in the ELF header of the kernel. Elilo loads the kernel at the indicated address, if possible. Eventually it jumps to this address. Elilo and EFI in general execute in physical address mode during boot time. The beginning of the actual kernel execution happens in *physical mode*, the code in _start (head.S) switches the kernel to virtual mode. This way, we have no dependency between the bootloader and the kernel w.r.t. virtual mappings. -- -Stephane
