[Qemu-devel] ARM9 emulation?

[Qemu-devel] ARM9 emulation?

[Andrew Lentvorski]

I was looking at the Qemu sites, but I didn't see a particularly clear 
discussion of what version(s) or ARM instructions can be emulated.

ARM7 (ARMv7) seems to be emulated.

Is there anything beyond that?

Thanks,

You didn't look very hard.  From http://www.qemu.org/qemu-doc.html#SEC46:

"The ARM Integrator/CP board is emulated with the following devices:

    * ARM926E or ARM1026E CPU"

ARM7 and ARMv7 are completely different things. One is a CPU model, the other 
is an architecture specification.

Ah.  I stand corrected.

You might want to put an ARM9 or ARM7 as a separate word somewhere on 
the page.  Putting "qemu arm9" into any of the search engines provides 
nothing useful.

Possibly, but wouldn't the documentation be the first place to look?

You're right, I probably should have dug into the documentation and 
found the fact that ARM926E is an ARM9.

However, do you really want to be invisible to people?  Try a Google on 
"arm9 emulator" or "arm7 emulator".  Even broken Nintendo DS emulators 
appear.

Qemu is *nowhere* to be found (err... correction: It appears as choice 
99 of "arm7 emulator").

If I hadn't already known about Qemu from a different context, I 
wouldn't even have found the *project* let alone found the chip number.

However, whether or not you add "ARM9" is your call, not mine.

If nothing else, at least this thread will hit the archives and get 
indexed.  That should improve things some.
