2022-08-11 Thread Felix Kuehling
On systems that support SMT (hyperthreading) schedule the bottom half of the KFD interrupt handler on the same core. This makes it possible to reserve a core for interrupt handling and have the bottom half run on that same core. On systems without SMT, pick another core in the same NUMA node, as
