[Qemu-devel] [PATCH 0/8] linux-user: enable NPTL on everything but x86

From: Peter Maydell
Subject: [Qemu-devel] [PATCH 0/8] linux-user: enable NPTL on everything but x86
Date: Fri, 12 Jul 2013 21:12:45 +0100

This patchset enables NPTL on all linux-user targets except i386 and
x86-64; this is a change for m68k, mipsn32, mipsn32el, mips64, mips64el,
or32, ppc64, ppc46abi32, sparc, sparc32plus, sparc64, unicore32
(but not plain ppc or plain mips). The first four patches have
been on list before and reviewed; the last four are new.

(i386 is addressed by Alex's patch; x86-64 I need to investigate
more closely to figure out how it's supposed to work; then we can
commit a patch which rips out CONFIG_USE_NPTL completely.)

Testing: I've tested with a chroot that or32 and sparc32plus work;
in both cases there were basic bugs in linux-user support (stat
didn't work on or32; pipe busted on sparc; see separate patches)
from which I conclude that these were simply untested targets,
so the bar for "make things at least not worse" is an extremely
low one. I cannot find any m68k binaries which don't die with
an illegal instruction very early on (probably because we emulate
coldfire and most m68k binaries assume 680x0), so I am treating
that target as basically also broken. I've also tested PPC and
PPC64 chroots, and of course the linux-user-0.3 testset from the wiki.

Peter Maydell (8):
  configure: Flip default of target_nptl
  configure: Don't say target_nptl="no" if there is no linux-user
  configure: Enable threading on all ppc and mips linux-user targets
  configure: Enable threading for unicore32-linux-user
  linux-user: Move includes of target-specific headers to end of qemu.h
  linux-user: Enable NPTL for OpenRISC
  linux-user: Enable NPTL for SPARC targets
  linux-user: Enable NPTL for m68k
