Anandtech takes a look at AMD’s new “Atom killing platform”

Anandtech takes a hands-on look at AMD’s new CPU+GPU combination platform, Brazos. It’s designed to compete in the low performance power, and mobile spaces.

How well will it perform, especially in comparison to next-gen Atom SOC, Sandy Bridge, or NVIDIA’s ION platform? Not sure yet, but one thing I know, it will be practically useless for Linux without decent driver support.

Update: Looks like some open source drivers are on the way..

Firewire iSight in Fedora?

Does anyone know how to get a firewire (ieee1394) iSight camera working in Fedora? I would have expected to see a video device come up in the kernel, but I seem to get nothing useful.

Google appears to be saturated with posts about the build in USB iSight cameras which need firmware.. not what I’m after.

Packages libdc1394 libraw1394 libavc139 are all installed. I’m trying to get it to work with Ekiga, but anything like dvgrab would be fine too – I remember in Debian/Ubuntu that I could install some libpt packages to get it working, but no such luck so far in Fedora..

This is what I see in the kernel when I plug it in..
firewire_core: skipped bus generations, destroying all nodes
firewire_core: skipped bus generations, destroying all nodes
firewire_core: giving up on config rom for node id ffc0
firewire_core: rediscovered device fw0
firewire_core: phy config: card 0, new root=ffc1, gap_count=5
firewire_core: phy config: card 0, new root=ffc1, gap_count=5
firewire_core: created device fw1: GUID 000a270004149a86, S400

I can’t see any usable video device being created there. Perhaps there’s a missing kernel driver, not sure.

Any suggestions? Thanks!

Getting MythTV working is easy

My good mate Tthu wanted to make himself a mythtv box. He bought an old Dell online and after a trip to the computer fair to get a 500GB SATA hard drive, low profile PCIe video card and a PCI digital TV tuner card, had everything he needed.

So, at my place we started the install. First thing I noticed was that the video cad had a passive heatsink that took up the space for the only PCI slot in the machine. I gave Tthu the option of waiting and trying to find a more suitable card, or hacking up the box to make it fit. Here began the first of our modifications..

After removing the heatsink from the GPU, we broke off the part that stuck out over the capacitors and proceeded to bend the other fins over. Isopropyl alchohol and some arctic silver later and it was back together again. Perfect. 🙂

Then we noticed that the case no longer shut because the hard drive bracket came ever so slightly down onto the back end of the card. I whittled away a little of the PCB, but it wasn’t quite enough. Due to the bracket design, we had to break off a part of the metal. This then allowed us to hack at the bracket itself and with Jason’s trusty multi-tool filed away a perfect gap for the card to slide into (with my trusty Dyson grabbing the filings, of course). Only problem was that the plastic slide rail for the hard drive couldn’t slide in anymore.. so we cut that in half. Done! 🙂

End result? Machine works perfectly with the video card running at about 80 degrees, which is well within spec. How long it all lasts for remains to be seen! Only problem now is that the TV aerial can’t get any signal in the basement.. Jason, where’s that multi-tool?
