6 menuconfig ARC_PLAT_EZNPS
7 bool "\"EZchip\" ARC dev platform"
8 select ARC_HAS_COH_CACHES if SMP
12 select EZCHIP_NPS_MANAGEMENT_ENET if ETHERNET
14 Support for EZchip development platforms,
15 based on ARC700 cores.
16 We handle few flavours:
17 - Hardware Emulator AKA HE which is FPGA based chasis
18 - Simulator based on MetaWare nSIM
19 - NPS400 chip based on ASIC
22 bool "ARC-EZchip MTM Extensions"
23 select CPUMASK_OFFSTACK
24 depends on ARC_PLAT_EZNPS && SMP
27 Here we add new hierarchy for CPUs topology.
31 At the new thread level each CPU represent one HW thread.
32 At highest hierarchy each core contain 16 threads,
33 any of them seem like CPU from Linux point of view.
34 All threads within same core share the execution unit of the
35 core and HW scheduler round robin between them.
