Still trying to ship an Aboriginal Linux release with the 3.1 kernel,
but the sparc target broke, as in QEMU's OpenBios goes:
Boot time fixup v1.6. 4/Mar/98 Jakub Jelinek (jj@ultra.linux.cz).
Patching kernel for srmmu[Fujitsu TurboSparc]/iommu
Fixup i f029ddfc doesn't refer to a valid instruction at
f00de648[95eea000]
halt, power off
And doesn't even boot Linux. A sparc-objdump -a on vmlinux says that
chunk has:
f00de63c: 84 0b 60 ff and %o5, 0xff, %g2
f00de640: 91 32 20 10 srl %o0, 0x10, %o0
f00de644: 85 28 a0 08 sll %g2, 8, %g2
f00de648: 98 0a 20 ff and %o0, 0xff, %o4
f00de64c: 03 00 00 3f sethi %hi(0xfc00), %g1
f00de650: 82 10 63 00 or %g1, 0x300, %g1 ! ff00
<cputypvallen+0xfef4>
f00de654: 90 0a 00 01 and %o0, %g1, %o0
Which means nothing to me.
I bisected it to this:
commit 9933fc0ac1ac14b795819cd63d05ea92112f690a
Author: Theodore Ts'o <tytso@mit.edu>
Date: Mon Aug 1 08:45:02 2011 -0400
ext4: introduce ext4_kvmalloc(), ext4_kzalloc(), and ext4_kvfree()
Introduce new helper functions which try kmalloc, and then fall back
to vmalloc if necessary, and use them for allocating and deallocating
s_flex_groups.
Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
The commit before that builds fine, this one doesn't.
I think it's triggering bad behavior in arch/sparc/mm/btfixup.c (at
least that's where the "valid instruction" error message comes from),
but I have no idea what this file is doing, and it was last touched in
2008. (I'm building with gcc 4.2.1 and binutils 2.17, both of which
were last touched around 2006, so that's not new either...)

The bug goes away if I even upgrade to 3.1.2, it's very precise and fiddly in a 'stars align' sort of way. It's building vanilla 3.1 with the attached .config, and doesn't happen if I change the .config too much. > Linux version 3.2.0-rc5 (slyfox@sf) (gcc version 4.2.1) #1 Sun Dec 11 11:08:25 FET 2011 > bootconsole [earlyprom0] enabled > ARCH: SUN4M > TYPE: SPARCstation 5 > Ethernet address: 52:54:00:12:34:56 > Boot time fixup v1.6. 4/Mar/98 Jakub Jelinek (jj@ultra.linux.cz).

(0.14.0 is here) I don't think it is a qemu bug. I marked up the fixup code with buckets of printk() and it didn't change anything, my understanding is it's btfixupprep.c producing bad output. But so far I haven't made any sense out of btfix.S and how it corresponds to the addresses the fixup code is working on. The address it's complaining about does not actually correspond to any of the symbols in the "objdump -x vmlinux" output, although they are between the ext4 symbols listed there... I put the broken image up at http://landley.net/sparc-image for the moment, but if you build 3.1 with the attached .config and the toolchain mentioned last time, it should reproduce for you. It's 100% reliable for me...

David: is this code correct? Or it's a compiler bug? I am sparc32 newbie. (C source and asm sources of function are in [1]) I think this kind of code is generated only in -Os. So to workaround it I tried this hack: > --- a/fs/ext4/super.c > +++ b/fs/ext4/super.c > ret = kmalloc(size, flags); > if (!ret) > ret = __vmalloc(size, flags, PAGE_KERNEL); > + > + asm __volatile__("nop":::"memory"); > + > return ret; > } (for both ext4_kvmalloc / ext4_kvzalloc. Attached workaround as a patch.) It forces compiler to geterate "usual" pattern for relocation. I think of 2 solutions: 1. trying to fix sparc/boot/btfixupprep.c and arch/sparc/mm/btfixup.c to distinct HI22 and LO10 relocations as different ones. Right now they are merged into one 'i' type and rely on instruction heuristics to fix it. 2. Add a hack to arch/sparc/mm/btfixup.c to recognize restore instruction as well Any others? Hope that helps.
