[Buildroot] [PATCH 0/6] Microblaze fixes

[Waldemar Brodkorb]

The microblaze buildoot support is in a bad state. 
Startup of the resulting image in Qemu is killed by OOM-killer.
These patches resolves the issues and the resulting images for
little endian and big endian are working fine. 
Network support is working now, too.

Waldemar Brodkorb (6):
  use default binutils for microblaze
  use default gcc 4.8.2 for microblaze
  upstream glibc 2.18/2.19 works fine with microblaze
  disable eglibc, no time to test
  temporary hack to fix linking error
  update to 3.14

You could depend on !BR2_microblaze for older versions since they won't
work.
Otherwise:

This patch works, but by it being temporary/hacky it should be
conditionally applied just for microblaze since you probably have no
idea how it can affect other architectures.

By the way, how is it that we're not interested in fixing things or
something like that?
(https://sourceware.org/ml/libc-help/2014-04/msg00027.html)
I'm using my (volunteer/spare) time looking at your patchset and testing
it, so i think that's not a fair assessment, and disabling eglibc
because "no time to test" and saying that at the same time sounds pretty
much like double-standards.
I'm not saying this to get you angry or anything like that, it's just
that you're stating it in a very public mailing list and it seems
utterly unfair to many BR contributors. Many people do what they can
when they can.

Now with that out of the way, care to respin this patch with the
consideration i mentioned above?

It's the default so you can just delete it.

Should use a separate copy of the patch for BE in the BE dir even if
it's the same.

Okay, sorry. I thought that there is no interest in my patches,
because I got no feedback at all. Looking at the traffic on the
mailinglist nearly every patch set gets some feedback after 2-3
days. My bug report about the microblaze OOM got no feedback, too. 
I stop whining now, and start hacking.

I will respin the patches after your gcc 4.9 patch set gets
committed. I tested with gcc 4.9 and the workaround for glibc/eglibc
is not required anymore.

Hi.
Ok, cool, now we're talking! :)

Great.
Only the gcc patch would need a respin i think, the rest can be
committed as they are.

[Buildroot] [PATCH 3/6] upstream glibc 2.18/2.19 works fine with microblaze

[William Welch]

Greetings,

When you say BR works fine for microblaze 'on QEMU', could you be more
specific?  little endian?  mmu? which 'defconfig' did you use with
buildroot?  Which version of QEMU, what command line?

I'd like to recreate your working setup and maybe that will give me a clue
to my troubles here...

I am trying to use the 'buildroot native toolchain' with a Spartan 6 little
endian microblaze MMU design, but I don't get very far with the native
toolchain. However, using the older 'external' toolchain boots linux fine.


thanks,

William

Hi.
It means all relevant buildroot qemu sample defconfigs boot to a login
prompt where you can login and get dhcp working on the emulated network
(if said config has networking).
For microblaze this means big and little endian with MMU, we don't have
a nommu configuration since i've never managed to get that working in a
satisfactory way.
And that's with Waldemar's patches, not as it is right now which broke
those qemu defconfigs when the toolchain was changed to the internal
backend.
I do not know if it's the toolchain to blame and/or some Qemu
limitation, i just know that Waldemar's patches fix it for what i have
at hand (no microblaze hardware, just emulation).
Regards.

[Buildroot] [PATCH 3/6] upstream glibc 2.18/2.19 works fine with microblaze

[William Welch]

Hi again,

Thank you for your help on this -- I should have said, that I am using the
'git' buildroot from earlier today ( a few hours ago), with no luck on the
native toolchain.  So am I correct, that, for example, using the 'git
buildroot', then ' make qemu_microblazeel_mmu_defconfig'  should build the
native toolchain and the resulting image should boot?  Or, maybe the
patches are not merged into the git tree yet?

I am not very skilled with qemu, so to confirm, are the directions in the
boards/qemu/microblazeel-mmu/readme.txt correct?  It is a little confusing,
since they mention the s3adsp1800, whereas the system.dts mentions a ML505
design.  Also the readme mentions qemu 1.7.0? I have 1.5.0 at the moment
but I can install 1.7.0 if required.

thank you,

William

Hi.
They are not merged yet, Waldemar was waiting for my gcc 4.9.x patches
to get merged (done) and is going to rebase when he has time probably.
The directions in the readme.txt are correct, i make it a habit of
testing them regularly.
I have seen different versions of Qemu failing to work properly, even if
newer or older, there's no rule for that, that's the reason i mention
the exact version there.
Unfortunately for the 2014.02 release when the toolchain changes were
shipped and the configs weren't updated so they are effectively broken
for the current toolchain (it may be that the current toolchain is
broken for real scenarios, i can't know).
Waldemar's last patch updates the qemu defconfigs to a nice and simpler
config without the need for an external dts and brings in networking
support as well.
For the "latest" i've used Qemu 2.0.0
And to make things nicer i've got a patchset that builds qemu within
buildroot to avoid the messy problem of different vesions available, it
just needs some proper docs i think and should get in, right guys? :)
Regards.

It seems that they will be merged now. I had not the time to respin a
new patch set because I didn't know how to do it correctly ;)
On sunday I got a nice git workshop by a friend and now I am able to
do it right. May be I will add a patch to the manual.

The changes do not show up yet on
http://git.buildroot.net/buildroot. May be Peter did not pushed the
changes yesterday.

If you want to use Qemu with -initrd you should use Qemu 1.7.x or
above. I only tested the microblaze stuff with Qemu 1.7.x and 2.0.
There is no need for a separate system.dts, because the Qemu
provided dtb matches the emulated hardware the best.
The default is to emulate s3adsp1800, but ml605 could be used, too.
Networking does work better with s3adsp1800 emulation.
Both little endian and big endian targets are tested with default
configuration.

Some more Qemu microblaze stuff can be found here:
http://blog.waldemar-brodkorb.de/index.php?archives/10-English.html&serendipity[lang_selected]=en&serendipity[user_language]=en

Unfortunately I was again wrong with my assumption that gcc 4.9.0
solves the linking error with libgcc_eh. I accidently had my patches
applied while testing with gcc 4.9.0. 

There seems to be a fix in https://github.com/Xilinx/gcc, but I am
unsure how to get it extracted. The snapshot for the gcc used in
buildroot does not contain the git history and the short tag from
the directory (Xilinx-gcc-b93bb00) is not available as an object in
the git repository. I would use git bisect to find the required
patch to gcc to avoid the eglibc/glibc workaround, but I don't know
which branch and commit is used as the basis for the gcc tarball.

Anyone know this?

So the glibc patch is still required.

Have fun
 Waldemar

Hi Waldemar, William.
It's in the process of being commited, i'm working with Peter on it.

I managed to track the issue down to
23c35173490ac2d6348a668dfc9c1a6eb62171f2 from xilinx-gcc git.
Basically that enables DWARF EH handling which is what's getting fixed
by including libgcc_eh.
It seems that gcc 4.9.0 with that patch ditches the new to patch glibc
(and possibly also eglibc). I'm testing that right now and will send
updated patches if that's true, in the meantime i've sent the glibc hack
patch conditional on microblaze (it's not commited yet).
The only "drawbrack" is that said patch doesn't apply cleanly to 4.8.x.
Regards.

Ah, so -
The "Buildroot Gottcha" is back.

Compare the view of:
http://git.buildroot.net/buildroot
with:
http://git.buildroot.net/buildroot/

At least at this moment, they are different (again).
