I would like to remove it from i386. Note also that > there > is no support for it on amd64. > > Maxime Hello, Yes, there is interest to resurrect ipkdb(4). Revisit of ipkdb(4) has been roughly scheduled after finishing LLDB, ptrace, sanitizers, (+kernel-sanitizers?), restoration of GDB and aligning kgdb to the reality... before that it's not the proper time to touch it, at least by myself. I plan to research current usability and how to make this kernel feature more MI, at least compatible with any network device. src/blob/trunk/doc/TODO.ptrace: - research ipkdb(4) When I raised questions about the current ipkgdb(4) implementation Christos suggested to leave it as it is to keep as a reference for future work.
