srat: harsh hot-pluggable memory check?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When parsing the memory affinity mappings in arch/x86/mm/srat.c:
acpi_numa_memory_affinity_init() I'm wondering if the hot-pluggable check is too harsh, 
as we consider an error if the hot-pluggable bit is set and CONFIG_MEMORY_HOTPLUG is not.

Based on the ACPI specs (v5):

"If the Enabled bit is set and the Hot Pluggable bit is also set. The
system hardware supports hot-add and hot-remove of this memory
region."

This only mentions that the system supports hot-plugging, and IMHO if the
user decides not to use CONFIG_MEMORY_HOTPLUG, it shouldn't be considered an error.
Therefore would it be ok to drop the check? Or am I missing something?

Thanks,
Davidlohr
