This portal is to open public enhancement requests against IBM Power Systems products, including IBM i. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).

New values for vpm_throughput_core_threshold (enabling a more dynamic setting of the threshold).
Currently, we set SMT and vpm_throughput_mode on many LPARs. In a few cases, we use vpm_throughput_mode_threshold - set to match the entitled cores (small LPARs) or to one less than entitled cores for larger LPARs. We limit the use vpm_throughput_mode_threshold to special cases, in part, because we need to change the value when we change the size of the LPAR.
Enable an additional value (for example '0' or 'E') for the vpm_throughput_core_threshold parameter. This value will set the threshold to the number of entitled (curr_proc_units) cores.
Enable an additional value (for example '-1') for the vpm_throughput_core_threshold parameter. This value will set the threshold to the one less than the number of entitled cores.
With these new, available values, we will not need to change the value for the vpm_throughput_core_threshold parameter when we change the size of the LPAR (expansion; reduction after migration to newer class processor, etc.). If an LPAR boots with less than the desired entitlement, the vpm_throughput_core_threshold will adjust accordingly.
