- PC (x86 or x86_64 processor) ;
- Sun4m/Sun4c/Sun4d (32-bit Sparc processor) ;
- Sun4u/Sun4v (64-bit Sparc processor, in progress) ;
- Malta board
- MIPS Magnum
- ARM Integrator/CP (ARM) ;
- ARM Versatile baseboard (ARM) ;
- ARM RealView Emulation/Platform baseboard (ARM) ;
- Siemens SX1 smartphone (OMAP310 processor) ;
