2018-05-16 | arch-arm: Add support for semihosting STDIO redirection | Andreas Sandberg | |
The Arm Semihosting layer currently assumes that the guest application shares STDIO with gem5. This makes it hard to distinguish application output from gem5's output and makes it impossible to redirect STDIN when running in interactive mode. Add support for custom STDIO redirection when instantiating the Semihosting model.

2018-02-19 | arch-arm: Add aarch64 semihosting support | Andreas Sandberg | |
Add basic support for Arm Semihosting 2.0 simulation calls [1]. These calls let the guest system call a simulator or debugger to request OS-like support when running bare metal code. With the exception of SYS_SYSTEM, this implementation supports all of the Semihosting 2.0 specification in aarch64.
