[Bug 1830726] [NEW] systemtap for hwe kernels
Public bug reported:
[Impact]
systemtap includes some kernel code compiled at runtime every time a
stap script is executed. This means that running a different kernel with
different ABIs may break systemtap. This is exactly what happens with
the hwe kernel.
We need to provide a separate systemtap package (systemtap-hwe for
example) that can be installed together with the hwe kernel.
For example on xenial, ideally, we may want to backport systemtap from
bionic and call it systemtap-hwe, similarly to what we're doing with the
kernel.
[Test Case]
For example, this is what happens in xenial with the hwe kernel
installed (linux-image-generic-hwe-16.04):
$ cat /home/ubuntu/hello.stp
#!/usr/bin/env stap
probe oneshot { println("hello world") }
$ sudo /home/ubuntu/hello.stp

Title:
systemtap for hwe kernels
Status in systemtap package in Ubuntu:
Confirmed
Status in systemtap source package in Xenial:
New
Bug description:
[Impact]
systemtap includes some kernel code compiled at runtime every time a
stap script is executed. This means that running a different kernel
with different ABIs may break systemtap. This is exactly what happens
with the hwe kernel.
We need to provide a separate systemtap package (systemtap-hwe for
example) that can be installed together with the hwe kernel.
For example on xenial, ideally, we may want to backport systemtap from
bionic and call it systemtap-hwe, similarly to what we're doing with
the kernel.
[Test Case]
For example, this is what happens in xenial with the hwe kernel
installed (linux-image-generic-hwe-16.04):
$ cat /home/ubuntu/hello.stp
#!/usr/bin/env stap
probe oneshot { println("hello world") }
$ sudo /home/ubuntu/hello.stp
