While support for PI futexes has been added in 2.6.18, it depends on
futex_atomic_cmpxchg_inatomic() being implemented, which has been
implemented later (or not yet implemented) on some architectures.
Below is the kernel version where the support has been added for main
and ports glibc architectures;
- i386: 2.6.18
- ia64: 2.6.19
- powerpc: 2.6.18
- s390: 2.6.18
- sparc: not implemented
- sparc64: 2.6.18
- sh: 2.6.23
- x86_64: 2.6.18
- alpha: not implemented
- arm: 2.6.28
- cris: not implemented
- hppa : 2.6.19
- m68k: not implemented
- mips: 2.6.18
Patches to fix the problem are following soon
