Limit | x86 | ARMv7 |
---|---|---|
System RAM | 32 GBa | 4 GBa |
Physical addressing | 36-bit | 32-bit |
CPUsb | 32c | 4 |
Virtual address spaced | 3.5 GB | 2 GB |
a You need to enable extended addressing by specifying the startup's -x option.
b The hardware might further limit the number of CPUs.
c If you plan to use more than 8 CPUs on an x86 platform, you must use the 6.5 or later version of procnto-smp with startup-bios or startup-apic.
d These are the absolute maximum limits for the virtual address space; you can reduce them by setting the RLIMIT_AS resource with setrlimit().
