Ug. Yes, but you have to use do_div and friends and we've got another case where something snuck past not using those helpers. I forget the right incantation to use on either nm or objdump to figure out just which function/file is doing it wrong.

Ok, so hopefully someone reading the list remembers and can provide us with a list of culprits. I can probably make some time to fix this even if the problem is not in sunxi code (all the commit does is enable CONFIG_SYS_64BIT_LBA which AFAIK does not directly influence any sunxi code).

So for now lets keep this in master and try to get it fixed, if it is not fixed in say 2 rc-s from now then we should probably revert the sunxi commit (and break large disks again).

Hans

So for now lets keep this in master and try to get it fixed, if it is not fixed in say 2 rc-s from now then we should probably revert the sunxi commit (and break large disks again).

OK, so I dug out the magic again (since there's a few other boards that fail on different toolchain with the same type of problem but another place).
First:

$ arm-linux-gnueabihf-nm /opt/linaro/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/../lib/gcc/arm-linux-gnueabihf/4.8.2/libgcc.a | grep -A 4 _udivdi3.o
This will show you all of the functions provided there.
Second:
$ for F in `find output-dir -name *.o`;do arm-linux-gnueabihf-nm $F 2>&1
| grep -q THATSYMBOL && echo $F;done

This will show you what object files have the function in question. Third:
arm-linux-gnueabihf-objdump -d ONE/OBJ/FILE.o | $PAGER
And hunt around for what function(s) here are calling the incorrect math function.
Fourth: Examine the C in question until you spot the "bad" division, correct to use a helper from include/linux/math64.h (and yes we have some other helpers too that are home grown but I am in favor of using the kernel ones).

2015-06-11 22:27 UTC #7 lore raw

(The post to the ML was here:
http://lists.denx.de/pipermail/u-boot/2015-June/216284.html)

I've been asking around a bit on the issue on IRC in #linux-sunxi and #u-boot (and originally contacted Hans on this). The user "Kasreyn" brought the subject up on #linux-sunxi, reporting that his Banana Pi (sun7i/A20) had trouble detecting the GPT partitioning of a 3TB SATA disk. Enabling CONFIG_SYS_64BIT_LBA solved that, but Kasreyn later confirmed that he experienced the same linking failure and had to use a softfloat toolchain to compile U-Boot (linaro bare metal - gcc-arm-none-eabi-4_9-2014q4-20141203-linux.tar.bz2).

As reported above, the U-Boot build fails when using an armhf toolchain:
http://pastebin.com/cwmyc2pE. The error messages involved indicate that changing lbaint_t to 64-bit introduces division functions (_divdi3 and _udivdi3) that the linker tries to satisfy from libgcc.a - which fails due to the incompatible ABI. For 32-bit _divsi3 and _udivsi3 seem to get satisfied by the corresponding assembler files in arch/arm/lib.

Unfortunately, in this case it's not a trival task to find and replace all the integer divisions that are affected by the change in lbaint_t size.

Regards, B. Nortmann

I'm not sure what todo about this, it works for me, and supporting disks larger then 2TB seems like a desirable feature in this time and age.
Ug. Yes, but you have to use do_div and friends and we've got another case where something snuck past not using those helpers. I forget the right incantation to use on either nm or objdump to figure out just which function/file is doing it wrong.

Ok, so hopefully someone reading the list remembers and can provide us with a list of culprits. I can probably make some time to fix this even if the problem is not in sunxi code (all the commit does is enable CONFIG_SYS_64BIT_LBA which AFAIK does not directly influence any sunxi code).
So for now lets keep this in master and try to get it fixed, if it is not fixed in say 2 rc-s from now then we should probably revert the sunxi commit (and break large disks again).
OK, so I dug out the magic again (since there's a few other boards that fail on different toolchain with the same type of problem but another place).
First:
$ arm-linux-gnueabihf-nm /opt/linaro/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/../lib/gcc/arm-linux-gnueabihf/4.8.2/libgcc.a | grep -A 4 _udivdi3.o
This will show you all of the functions provided there.
Second:
$ for F in `find output-dir -name *.o`;do arm-linux-gnueabihf-nm $F 2>&1
| grep -q THATSYMBOL && echo $F;done

Quoted 9 lines

This will show you what object files have the function in question. Third:
arm-linux-gnueabihf-objdump -d ONE/OBJ/FILE.o | $PAGER
And hunt around for what function(s) here are calling the incorrect math function.
Fourth: Examine the C in question until you spot the "bad" division, correct to use a helper from include/linux/math64.h (and yes we have some other helpers too that are home grown but I am in favor of using the kernel ones).

OK, tracking down where is even easier than I recalled:

$ $PAGER temp/u-boot.map
...
/usr/lib/gcc/arm-linux-gnueabihf/4.7/libgcc.a(_ashldi3.o)
