It is a bit of a pain to log EFI boot-services calls at present. The output goes to the console so cannot easily be inspected later. Also it would be useful to be able to store the log and review it later, perhaps after something has gone wrong.
This series makes a start on implementing a log-to-buffer feature. It provides a simple 'efidebug log' command to inspect the buffer. For now, only memory allocations are logged.
In my previous review I suggested to move your work to the level of the logging library lib/log.c.
Well, we could do that, if we actually have a need for programmatic logging of other subsystems.
Why are you reiterating your series without exposing why an EFI specific solution. should be desireable?
I don't see that need yet, or at least, not for the purpose I am heading towards. In any case, we can easily refactor the code later if it is needed. For now I believe that this logging feature will help to tame some of the troubles we have.
