OpenJDK6 m68k port : what is the current status of helper __kernel_atomic_cmpxchg_32 ?
Im working on a patch to make OpenJDK6 compile and run on m68k.
The missing piece for the implementation is a way to do a atomic cmpxchg
from userspace. If we invent a way of doing that then the missing gcc
can be implemented using cmpxchg, this have already been done on the ARM
port using a exisiting kernelhelper for cmpxchg.
I have noticed that there is ongoing work of creating a
__kernel_atomic_cmpxchg_32 helper for m68k using vDSO:
Someone know the status of this implementation? Is there any kernel
Cheers and have a great day!
