[Qemu-devel] [PATCH v1 00/22] Steps towards per CPU address-spaces

[edgar . iglesias]

From: "Edgar E. Iglesias" <address@hidden>

Hi,

I'm looking at modeling systems where multiple CPUs co-exist with
different views of their attached buses/devs.

With this series I'm trying to take some steps towards having
an address-space per CPU. It's not complete but good enough for
making it possible to model (to some extent) CPU local memories
for MicroBlaze systems in emulation mode (tcg). I'm updating the
petalogix-ml605 here and will follow-up later with the petalogix-s3adsp.

There is lots of future work needed, for example to transform more of
the cpu_* bus accessing functions. To add more usage of AddressSpace
properties to pass on address spaces to DMA models. Qtest mechanisms
to target specific address spaces, etc...

Cheers,
Edgar
