Piccoli <gpiccoli@igalia.com> # Date: Wed Apr 27 19:49:02 2022 -0300 # # powerpc/setup: Refactor/untangle panic notifiers # # The panic notifiers infrastructure is a bit limited in the scope of # the callbacks - basically every kind of functionality is dropped # in a list that runs in the same point during the kernel panic path. # This is not really on par with the complexities and particularities # of architecture / hypervisors' needs, and a refactor is ongoing. # # As part of this refactor, it was observed that powerpc has 2 notifiers, # with mixed goals: one is just a KASLR offset dumper, whereas the other # aims to hard-disable IRQs (necessary on panic path), warn firmware of # the panic event (fadump) and run low-level platform-specific machinery # that might stop kernel execution and never come back. # # Clearly, the 2nd notifier has opposed goals: disable IRQs / fadump # should run earlier while low-level platform actions should # run late since it might not even return. Hence, this patch decouples # the notifiers splitting them in three: # # - First one is responsible for hard-disable IRQs and fadump, # should run early; # # - The kernel KASLR offset dumper is really an informative notifier, # harmless and may run at any moment in the panic path; # # - The last notifier should run last, since it aims to perform # low-level actions for specific platforms, and might never return. # It is also only registered for 2 platforms, pseries and ps3. # # The patch better documents the notifiers and clears the code too, # also removing a useless header. # # Currently no functionality change should be observed, but after # the planned panic refactor we should expect more panic reliability # with this patch. # # Signed-off-by: Guilherme G.
