| 3 | +Alpha emulation structure: | |
| 4 | +cpu.h : CPU definitions globally exported | |
| 5 | +exec.h : CPU definitions used only for translated code execution | |
| 6 | +helper.c : helpers that can be called either by the translated code | |
| 7 | + or the Qemu core, including the exception handler. | |
| 8 | +op.c : Alpha dedicated micro-operations used by the code translator | |
| 9 | +op_helper.c : helpers that can be called only from micro-operations | |
| 10 | +op_helper.h : micro-operations helpers prototypes | |
| 11 | +op_helper_mem.h : micro-operations templates | |
| 12 | + for load and stores accesses helpers | |
| 13 | +op_mem.h : micro-operations templates for load and stores accesses | |
| 14 | +op_template.h : micro-operation templates for register moves | |
| 15 | +translate.c : Alpha instructions to micro-operations translator | |
| 16 | + | |
| 17 | +Code translator status: | |
| 18 | +The Alpha CPU instruction emulation should be quite complete with the | |
| 19 | +limitation that the VAX floating-point load and stores are not implemented. | |
| 20 | +The 4 MMU modes are implemented. | |
| 21 | + | |
| 22 | +Linux user mode emulation status: | |
| 23 | +a few programs start to run. Most crash at a certain point, dereferencing a | |
| 24 | +NULL pointer. It seems that the UNIQUE register is not initialized properly. | |
| 25 | +It may appear that old executables, not relying on TLS support, run but | |
| 26 | +this is to be prooved... | |
| 27 | + | |
| 28 | +Full system emulation status: | |
| 29 | +* Alpha PALCode emulation is in a very early stage and is not sufficient | |
| 30 | + to run any real OS. The alpha-softmmu target is not enabled for now. | |
| 31 | +* no hardware platform description is implemented | |
| 32 | +* there might be problems in the Alpha PALCode dedicated instructions | |
| 33 | + that would prevent to use a native PALCode image. | |
