Alpha emulation structure:
|
|
cpu.h : CPU definitions globally exported
|
|
exec.h : CPU definitions used only for translated code execution
|
|
helper.c : helpers that can be called either by the translated code
|
|
or the Qemu core, including the exception handler.
|
|
op_helper.c : helpers that can be called only from TCG
|
|
helper.h : TCG helpers prototypes
|
|
translate.c : Alpha instructions to micro-operations translator
|
|
|
|
Code translator status:
|
|
The Alpha CPU instruction emulation should be quite complete with the
|
|
limitation that the VAX floating-point load and stores are not tested.
|
|
The 4 MMU modes are implemented.
|
|
|
|
Linux user mode emulation status:
|
|
a few programs start to run. Most crash at a certain point, dereferencing a
|
|
NULL pointer. It seems that the UNIQUE register is not initialized properly.
|
|
It may appear that old executables, not relying on TLS support, run but
|
|
this is to be prooved...
|
|
|
|
Full system emulation status:
|
|
* Alpha PALCode emulation is in a very early stage and is not sufficient
|
|
to run any real OS. The alpha-softmmu target is not enabled for now.
|
|
* no hardware platform description is implemented
|
|
* there might be problems in the Alpha PALCode dedicated instructions
|
|
that would prevent to use a native PALCode image.
