Subject: /sys/bus/pci/devices/[interface]/numa_node is -1
Date: Thu, 31 Oct 2013 09:18:10 +0900 [thread overview]
Message-ID: <XNM7$4$0$4$$1$2$9$A$9000042U5271a1a9@hitachi.com> (raw)
Hi,
I try to run DPDMK testpmd and failed.
I found that EAL will read /sys/bus/pci/devices/[interface]/numa_node file
and initilize the PCI devices.
My PC does not support NUMA, it has only one processor.
However, initial value of numa_node of the device is -1.
I found some suggestion that BIOS should support
the proper ACPI features to detect PCI devices affinity to CPU.
Otherwise, the numa_node will be -1.
However, I can not find the proper option in the BIOS.
Does anyone have the same problem or can give some suggestion?
Thank you.
Cheng Luo.
