[User-mode-linux-devel] UML/PPC status

[Chris E. <cem...@ch...>]

I've now got as far as linking the executable under PPC linux,
basically by copying bits from arch/ppc until it stopped having
unresolved symbols.

The first time I ran it it exited from remap_data("rw-") saying
"remap_data couldn't find data segment" because there were no entries
in /proc/self/maps with those permissions:

10000000-1016a000 rwxp 00000000 03:0d 339044 /home/cme20/working/umlinux/linux/linux
1016a000-1019f000 rwxp 00000000 00:00 0
7ffff000-80000000 rwxp 00000000 00:00 0

Is something actually wrong here, or should it only exit if both
remap_data("rwx") and remap_data("rw-") fail?

After commenting out the "exit(1)" line it gets as far as saying
"POSIX conformance testing by UNIFIX" and then seems to be spinning in
the tracing thread.  I haven't looked at what it's trying to do yet.

I hope to get around to building a patch later today.
