hi all, I am using 24KEC SOC, i want to support larger more than 512MB RAM. The mips32 architure in Kseg0/Kseg1, such as: 0x8000,0000 ~ 0x92c0,0000 # 300MB for RAM 0x92c0,0000 ~ 0xa000,0000 # 212 for I/O register so, mips32 only support 300MB memory, i dont how to support more than 512MB in linux-mips kernel , such as 2GB memory? it is using HIGHMEM strategy for kernel(ZONE_HIGHMEM)? Best, Figo.zhang |
