Thank you for your reply.

Hi Sunil,

yes, the cacheinfo task is still open. There are many things that are still not
implemented in OpenRISC, you can always just look under the kernel
Documentation/features.
For example:
< shorne@antec ~/work/linux > grep -r -e openrisc.*TODO
Documentation/features | column -t
Documentation/features/vm/huge-vmap/arch-support.txt: |
openrisc: | TODO |
Documentation/features/vm/ELF-ASLR/arch-support.txt: |
openrisc: | TODO |
Documentation/features/vm/ioremap_prot/arch-support.txt: |
openrisc: | TODO |
Documentation/features/vm/pte_special/arch-support.txt: |
openrisc: | TODO |
Documentation/features/perf/kprobes-event/arch-support.txt: |
openrisc: | TODO |
...
Got it. I did find this list in the online documentation [1] but I couldn't find
the cacheinfo task listed there.
How far have you come with OpenRISC so far? If you haven't already I suggest
working through:
- Get a simulator, I use QEMU for most development as it's faster and supports
more memory than most FPGA. Final verification can be done on an FPGA.
- Get a working compiler toolchain.
- Compile and boot the openrisc kernel.
- Build a userspace environment, either buildroot, toybox or busybox.
I have some tools to help with this in or1k-utils [1], also there are prebuilt
environments and docs in the linux kernel [2] and qemu [3].
I don't have an environment set up yet. I'll start with the steps above. I'll
use
QEMU for development. I don't have an FPGA with me currently.
At the momoment, I am also thinking of what to work on next for OpenRISC, there
is:
- kexec
- jump_label
- kprobes
- perf_events
- ftrace
Is the virtio task [2] also still a part of the roadmap? I can't find that
either
in the TODO list.
