[Valgrind-users] Valgrind just hangs for MIPS64 Cavium Octeon

[Matt B. <Mat...@al...>]

To get Valgrind working for my MIPS64 Cavium chip so far I have applied
a couple of patches.

1. Initially I was seeing the "Valgrind's memory management: out of
memory:" error. This was due to the PAGE_SIZE in valgrind being
incorrect. To support an 8kB page size I used the patch from here:

https://bugs.kde.org/show_bug.cgi?id=342356.

After applying this 'valgrind -h' worked correctly. Then when I attempted to run
valgrind with a program I would see this error 

"valgrind: m_coredump/coredump-elf.c:261 (fill_prstatus): Assertion 'sizeof(*regs) == sizeof(prs->pr_reg)' failed"

I believe this is due to Cavium specific instructions not being
supported currently by Valgrind. I applied the patch from here:

https://bugs.kde.org/show_bug.cgi?id=341036

However now the error no longer occurs but it looks to me like Valgrind
is just hanging, see below:

It stays like this forever. Has anyone encountered this before?
