- | More info will be added here soon... | + | ===== Current ARM32 Support ===== |
+ | |||
+ | gem5-gpu currently has limited support for ARM32, and even this functionality has not been tested extensively. Specifically, ARM is currently supported in syscall emulation mode, but not full-system mode. The version of gem5 currently used within gem5-gpu only supports ARMv7, which is a 32-bit architecture, so the maximum physical memory size for a simulated system under ARM is 4GB. | ||
+ | |||
+ | As further support is developed, the information here may change. | ||
==== Build ==== | ==== Build ==== | ||
+ | |||
+ | To build for the ARM CPU ISA, simply pass the --default=ARM parameter to scons when building: | ||
+ | |||
<code> | <code> | ||
- | cd gem5 | + | [gem5-gpu] cd gem5 |
- | scons build/VI_hammer/gem5.opt --default=ARM EXTRAS=../gem5-gpu/src:../gpgpu-sim/ PROTOCOL=VI_hammer GPGPU_SIM=True | + | [gem5-gpu/gem5] scons build/VI_hammer/gem5.opt --default=ARM EXTRAS=../gem5-gpu/src:../gpgpu-sim/ PROTOCOL=VI_hammer GPGPU_SIM=True |
</code> | </code> | ||
+ | |||
+ | From this point, you can proceed to run gem5-gpu as described in the [[start|quick start guide]] as long as your benchmarks are built for the ARM CPU ISA, which is described in the [[benchmarks|benchmarks guide]] | ||
