[PATCH v5 1/5] powerpc/smp: Enable Asym packing for cores on shared processor

2023-12-14 Thread Srikar Dronamraju
If there are shared processor LPARs, underlying Hypervisor can have more virtual cores to handle than actual physical cores. Starting with Power 9, a big core (aka SMT8 core) has 2 nearly independent thread groups. On a shared processors LPARs, it helps to pack threads to lesser number of cores so
