witherspoon-debug

Description

The OpenBMC debugtools tarball clashes with the filesystem layout of witherspoon systems, and contains a number of other outstanding issues with respect to the tools it deploys. The debug script here documents and executes the workarounds necessary to make it functional.

Usage

./debug [USER@]HOST TARBALL

For example:

$ ./debug root@my-witherspoon obmc-phosphor-debug-tarball-witherspoon.tar.xz

Notes

The script will:

1. Ensure /usr/local is a tmpfs mountpoint (may not be if system is configured for Field Mode)
2. Deploy the debugtools tarball to /usr/local
3. Make perf(1) work by
   1. Installing a fake expand(1) if necessary
   2. Fixing the objdump(1) symlink
   3. Disabling perf(1)'s buildid tracking (fills the RW filesystem)
4. Make latencytop(1) work by deploying and symlinking libncurses{,w}.so
