With the GFP_ATOMIC, behaviour is the same as before for me.So you still get -ENOMEM failure on your platform. It is fine, just that I am bit curious to know why as it succeeds at device_initcall later. I was hoping this might fix your memory allocation failure.Correct.
I take that back. On today's next with patch 2 applied, I don't see a problem with no memory, so this does appear to have sorted the memory allocation failure. Sorry for misleading you & thanks! With my patches for store_cpu_topology on RISC-V I do see it though, when called on the boot cpu. I must have mixed up which I had tested. I have a fix for that though & will update my patches later. Thanks & apologies!
