Guanglei can you confirm if b2a tool works fine if built in 32 bit mode? Ananth/Amit have we tested 32bit user space tools support for systemtap? Although IBM usually recommends building user space tools in 32 bit mode even for 64bit PPC kernels for performance reasons in this particular case we don't see a big advantage of it, so if you want to support only one version of user space tools you can choose to build all the user space tools only in 64bit and no need to build 32bit. >stack-s390.c contains code that prints registers content >using 16 hexadecimal digits. Is it really support for s390x? Or both? >Is it possible to use 31-bit version of stap with 64-bit kernel in this >case? > > > Yes technically it is possible to use 31 bit user space tools with 64bit kernel but systemtap is not tested that way at this time. As Dave replied you only need to carry 64bit user space tools for systemtap on s390 at this time. Please let me know if you have any further questions.
