With structure elf64_phdr, field p_paddr is physical address of the
segment. And it is convenient for qemu to calculate the physical
address when directly boot ELF kernel image.
Otherwise QEMU needs convert virtual address p_vaddr into physical
address, the conversion logic assumes that DMW method is used where
48 bit physical address is supported. However with direct MMU mapping
method with start address from 0xFFFF800000000000, only 47 bit physical
address is supported. QEMU cannot assume the kernel behavior at kernel
loading stage.
Here add physical address indication in ELF program header, it is
convenient to get physical kernel loading address.
Here is output with command readelf -l vmlinux with patch:
Elf file type is EXEC (Executable file)
Entry point 0x90000000015f5000
There are 2 program headers, starting at offset 64
Program Headers:
Type Offset VirtAddr PhysAddr
FileSiz MemSiz Flags Align
LOAD 0x0000000000010000 0x9000000000200000 0x0000000000200000
0x000000000293b000 0x0000000002a79b98 RWE 0x10000
And output with command readelf -l vmlinux without the patch:
Elf file type is EXEC (Executable file)
Entry point 0x90000000015f5000
There are 2 program headers, starting at offset 64
Program Headers:
Type Offset VirtAddr PhysAddr
FileSiz MemSiz Flags Align
LOAD 0x0000000000010000 0x9000000000200000 0x9000000000200000

v1 ... v2:
1. Set LOAD_OFFSET with PAGE_OFFSET rather than CACHE_BASE, since it
is generic with PAGE_OFFSET.
2. Add AT information with missing edata_padding section.

Oops, it is the obvious compile issue. And I am messed with parallel
tasks and do not notice this, what I test is old kernel.

Add this part to the patch is enough.
