The CPU topology isn't enabled on arm/virt machine yet, but we're
|
|
|
586cba |
going to do it in next patch. After the CPU topology is enabled by
|
|
|
586cba |
next patch, "thread-id=1" becomes invalid because the CPU core is
|
|
|
586cba |
preferred on arm/virt machine. It means these two CPUs have 0/1
|
|
|
586cba |
as their core IDs, but their thread IDs are all 0. It will trigger
|
|
|
586cba |
test failure as the following message indicates:

This fixes the issue by providing comprehensive SMP configurations
|
|
|
586cba |
in aarch64_numa_cpu(). The SMP configurations aren't used before
|
|
|
586cba |
the CPU topology is enabled in next patch.
