A few commits ago, in aeecbc87b73, I've implemented command line
|
|
|
7548c0 |
generation for ACPI HMAT. For this, we need to know if at least
|
|
|
7548c0 |
one guest NUMA node has vCPUs. This is tracked in
|
|
|
7548c0 |
@masterInitiator variable, which is initialized to -1, then we
|
|
|
7548c0 |
iterate through guest NUMA nodes and break the loop if we find a
|
|
|
7548c0 |
node with a vCPU. After the loop, if masterInitiator is still
|
|
|
7548c0 |
negative then no NUMA node has a vCPU and we error out. But this
|
|
|
7548c0 |
exact check was missing comparison for negativeness.
