Hello,O.K, good feedback we will try to add a section on the web site to indicate supported architectures, thanks.
Currently Debian package for systemtap builds on all release architectures, but I think it is not useful on some of them. So, I am going to drop support of those architectures.
I cannot find list of supported architectures in systemtap's source or
website, so I'll try to guess.
src/runtime contains the following files:We also support regular 32bit x86.
stack-x86_64.c
stack-ia64.c
stack-ppc64.c
stack-s390.c
Are that all of supported architectures?Do you have interest for any other architectures support?
Is it possible to use systemtapI believe one should able to run 32bit user space tools although kernel has support only for 64bit PPC. 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?
on 64-bit ppc system with 32-bit userspace (including stap, staprun,
lket-b2a ...)?
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.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?
