aarch64: relocation 0x105 is not implemented yet.

aarch64: relocation 0x105 is not implemented yet.

[Andrey Borzenkov]

I tried to build RPM for aarch64; it fails building image with

[ 1273s] + ./grub-mkimage -O arm64-efi -o grub.efi --prefix= -d
grub-core all_video boot cat chain configfile echo efinet font gfxmenu
gfxterm gzio halt iso9660 jpeg minicmd normal part_apple part_msdos
part_gpt password_pbkdf2 png reboot search search_fs_uuid search_fs_file
search_label sleep test video fat loadenv linux ext2 btrfs ext2 xfs jfs
reiserfs efinet tftp mdraid09 mdraid1x lvm
[ 1273s] ./grub-mkimage: error: relocation 0x105 is not implemented yet.

Tools are

gcc48-4.8.2+r203692-2.1
binutils-2.24-1.1

This is native build, no cross.

[  420s] checking build system type... aarch64-unknown-linux-gnu
[  420s] checking host system type... aarch64-unknown-linux-gnu
[  420s] checking target system type... aarch64-suse-linux-gnu


I do not have access to build system itself (OBS) only logs are
available.

This shouldn't happen as those relocation assume 32-bit range. Is
-mcmodel=large properly passed?

Still the same even after adding -mcmodel=large to CCASFLAGS. Is it
possible that compiler generates small relocation where appropriate even
with -mcmodel=large?

This shouldn't matter for asm though: it's a compiler option instructing the
compiler what code sequences to use for indirect calls/accesses.

It shouldn't, but difficult to say without knowing more details.
Can you run the mkimage with -v and pinpoint the triggering module?

This comes from .eh_frame section and fails for kernel.exec already. 

RELOCATION RECORDS FOR [.eh_frame]:
OFFSET           TYPE              VALUE 
000000000000001c R_AARCH64_PREL32  .text+0x0000000000009b70
0000000000000044 R_AARCH64_PREL32  .text+0x0000000000009b78

Also there are ABS32 relocations in various .debug_* sections but I
presume they are handled by --strip-unneeded.

Ah, yes (Fedora also saw this):
https://plus.google.com/u/0/106265217227408958782/posts/RYNT8RwFHDB

While it might be interesting to dig out what causes this toolchain difference
vs. Linaro, I am reasonably confident this relocation cannot be generated
in actual C code with -mcmodel=large. So my suggestion would be to ignore
this relocation. Or should we explicitly strip .eh_frame?

If it is not needed to run the binaries on target - I sure suggest
stripping it off. I was not sure as I expected --strip-unneeded to do it
in this case.

Ignoring does not sound right in case we actually hit in in code.

Umm, I'm officially going to go make some coffee.

On arm64_efi stripflags obviously.

Yes, this works (i.e. - grub-mkimage does not fail). Of course, module
relocation happens at run time and I do not have hardware or software to
test it - could you do it? You can download RPM here:

Fixes grub-mkimage error

Thanks - I'll give it a go tonight (need to leave now).
If you can't wait, you can read my instructions for how to set up
the software model environment:

Thanks, but lacking liblzma.so.5 and libdevmapper.so.1.03 - any chance
you could pass those across?
