ATTR_FREQ_PROC_REFCLOCK TARGET_TYPE_SYSTEM The frequency of the processor refclock in MHz. Provided by the Machine Readable Workbook. This is read by the set_ref_clock HWP to find out the desired frequency. This can be overridden to adjust the refclock frequency. uint32 ATTR_FREQ_MEM_REFCLOCK TARGET_TYPE_SYSTEM The frequency of the memory refclock in MHz. Provided by the Machine Readable Workbook. This is read by the set_ref_clock HWP to find out the desired frequency. This can be overridden to adjust the refclock frequency. uint32 ATTR_FREQ_CORE_FLOOR TARGET_TYPE_SYSTEM The lowest frequency that a core can be set to in MHz. This is the same for all cores in the system. TODO Provided by TBD. Current thinking is MRW or MVPD. If MRW then this attribute will stay here as a platInit attribute. If MVPD then this attribute will move to proc_mvpd_attributes.xml. uint32 ATTR_FREQ_PB TARGET_TYPE_SYSTEM The frequency of a processor's PB chiplet in MHz. This is the same for all PB chiplets in the system. This is set by a HWP that runs after SBE HWPs setup the PB PLL. It reads ATTR_FREQ_PROC_REFCLOCK and the PB PLL settings. uint32 ATTR_FREQ_A TARGET_TYPE_SYSTEM The frequency of a processor's A-bus chiplet in MHz. This is the same for all A-bus chiplets in the system. This is set by the HWP that sets up the A-bus PLL. uint32 ATTR_FREQ_X TARGET_TYPE_SYSTEM The frequency of a processor's X-bus chiplet in MHz. This is the same for all X-bus chiplets in the system. This is set by the HWP that sets up the X-bus PLL. uint32
