[Qemu-devel] Re: [RFC] [PATCH] add ahci support into qemu

[Elek Roland <elek.roland@gmail.com>]

Hi all,

I am the GSoC student working on the project. I haven't tried the patch
yet, but I've read the code. It could use general cleanup and a lot of
development indeed, but otherwise it looks like a good base to build
complete support on so far. I'm going to try the patch in practice as
soon as I finish my university project. (It's due today.)

Chong, I'd be happy to stay in touch with you. I'm going to work on this
in the summer full time.

Regards,
Roland
