We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

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 proved...
|
|
|
|
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.
