The npk_log is a log destination for the hypervisor, similar to the console_log and the mem_log. It can be enabled/disabled/configured by the SOS kernel via the hypercall HC_SETUP_HV_NPK_LOG. The configuration includes: 1. Set the MMIO base address of the reserved NPK master. 2. Set the log level of the hypervisor NPK log. After that, the npk_log can be enabled to write the hypervisor logs to the MMIO address of the reserved NPK master with a simple header.
