Roger Pau Monné 7e748038cd amd64: set the correct LMA values ... The current linker script generates program headers with VMA == LMA: Entry point 0xffffffff802e7000 There are 6 program headers, starting at offset 64 Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flags Align PHDR 0x0000000000000040 0xffffffff80200040 0xffffffff80200040 0x0000000000000150 0x0000000000000150 R E 8 INTERP 0x0000000000000190 0xffffffff80200190 0xffffffff80200190 0x000000000000000d 0x000000000000000d R 1 [Requesting program interpreter: /red/herring] LOAD 0x0000000000000000 0xffffffff80200000 0xffffffff80200000 0x00000000010559b0 0x00000000010559b0 R E 200000 LOAD 0x0000000001056000 0xffffffff81456000 0xffffffff81456000 0x0000000000132638 0x000000000052ecf8 RW 200000 DYNAMIC 0x0000000001056000 0xffffffff81456000 0xffffffff81456000 0x00000000000000d0 0x00000000000000d0 RW 8 GNU_STACK 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000 RWE 8 This is fine for the FreeBSD loader, because it completely ignores p_paddr and instead uses p_vaddr with a hardcoded offset. Other loaders however acknowledge p_paddr (like the Xen ELF loader), in which case they will try to load the kernel at the wrong place. Fix this by adding an AT keyword to the first section specifying the physical address, other sections will follow suit, so it ends up looking like: Entry point 0xffffffff802e7000 There are 6 program headers, starting at offset 64 Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flags Align PHDR 0x0000000000000040 0xffffffff80200040 0x0000000000200040 0x0000000000000150 0x0000000000000150 R E 8 INTERP 0x0000000000000190 0xffffffff80200190 0x0000000000200190 0x000000000000000d 0x000000000000000d R 1 [Requesting program interpreter: /red/herring] LOAD 0x0000000000000000 0xffffffff80200000 0x0000000000200000 0x00000000010559b0 0x00000000010559b0 R E 200000 LOAD 0x0000000001056000 0xffffffff81456000 0x0000000001456000 0x0000000000132638 0x000000000052ecf8 RW 200000 DYNAMIC 0x0000000001056000 0xffffffff81456000 0x0000000001456000 0x00000000000000d0 0x00000000000000d0 RW 8 GNU_STACK 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000 RWE 8 Tested on bare metal using the native FreeBSD loader and grub2 from TRUEOS.
