This is fixed by adding "export TARGET_CCASFLAGS := -fno-PIE" to debian/rules.

Yes, this is a known issue. It's possible I made a mistake when
applying Eric's patches to the grub2 package for sparc64.

We have discussed that on the list, if I remember correctly.

JFYI

Installed another LDOM yesterday, ports have 2.02-2+sparc64.1 version

Eric,

I tried this on 2 my testing LDOMs, one with sun disk/partition table,
and another one with gpt disk/partition table.
As well on an older sun4u v215 physical machine (sun disks/partition table).

Can you please suggest how do I install with gpt disk? Details is below.


Ldom with sun disk had no problems with installing by wiki guide, and
booted with grub ok:

Re: grub2 with SPARC support available for testing

I tested grub2_2.02~beta3-4+sparc64.1 via the 2016-05-04 install media on 
t5220[1] hardware as well as in an ldom[2] and had no issues with the 
installation or subsequent boot via grub

[1] https://distortion.io/p/19 
[2] https://distortion.io/p/20 

Based on the discussion in #sparc about T5240 grub2 memory errors/memory-region 
issues, let me know if you want me to try an 'invalid' memory config on the 
T5220, or do any more debugging. I've also got a T5440 which can also be used 
for debugging various memory configurations if needed -- I just need to find 
sufficient electricity for it first.

I uploaded grub2_2.02~beta3-4+sparc64.1 to "unreleased" today which is
based on Eric's latest sparc-next-v2 branch [1]. This new version fixes
the build problems on non-sparc* targets. I'm not sure if it addresses

Re: grub2 with SPARC support available for testing

2017-01-23 Thread John Paul Adrian Glaubitz 
Hello!

A quick follow up since several people seem to have not read the
instructions carefully enough.

1) You have to use the version with the "+sparc64" suffix in the
   version number available from the "unreleased" repository.

   *This* is the correct version:

   root@deb4g:~# apt-cache policy grub2
   grub2:
 Installed: (none)
 Candidate: 2.02~beta3-3+sparc64
 Version table:
2.02~beta3-3+sparc64 500
   500 http://ftp.ports.debian.org/debian-ports unreleased/main sparc64 
Packages
   root@deb4g:~#

   The standard grub2 package from "unstable" does *not* include
   Eric's patches.

2) Please send any reports to *this* mailing list. Please do *not*
   send me any private mail. These issues are supposed to be discussed
   on the list and in public so others can see the discussion as well,
   including upstream developers.

Thanks,
Adrian

grub2 with SPARC support available for testing

2017-01-22 Thread John Paul Adrian Glaubitz 
Hi!

I just uploaded grub2_2.02~beta3-3+sparc64 to Debian "unreleased" which
contains an additional set of 15 patches by Eric Snowberg (CC'ed) which
improve SPARC in grub2 and add support for modern SPARC hardware through
the SPARC T7.

According to Eric, grub2 should work on SPARC machines from T1 through
T7, apparently older sun4u machines are not 100% supported but might
work as well. If I remember correctly, he said that adding support for
older sun4u hardware is possible in the future.

In any case, it would be great if this package could be tested by as
many users as possible. Please report your results back to the list,
Eric will be very interested to hear any feedback. The more testing we get,
the more likely we find additional bugs and also can get the patches
hopefully merged upstream.

As the packages were just uploaded to "unreleased", it might take a few
hours until the packages show up in the archive. In any case, make sure
the version number contains the "+sparc64" suffix. To use "unreleased",
you need to have the following line in your /etc/apt/sources.list:

deb http://ftp.ports.debian.org/debian-ports/ unreleased main

Thanks,
Adrian
