Wireless PCIe To Enable Remote Graphics Cards

Posted by timothy on from the no-cat-involved dept.

J. Dzhugashvili writes "If you read Slashdot, odds are you already know about WiGig and the 7Gbps wireless networking it promises. The people at Atheros and Wilocity are now working on an interesting application for the spec: wireless PCI Express. In a nutshell, wPCIe enables a PCI Express switch with local and remote components linked by a 60GHz connection. The first applications, which will start sampling next year, will let you connect your laptop to a base station with all kinds of storage controllers, networking controllers, and yes, an external graphics processor. wPCIe works transparently to the operating system, which only sees additional devices connected over PCI Express. And as icing on the cake, wPCie controllers will let you connect to standard Wi-Fi networks, too."

      Some recent systems have IOMMUs which provide privilege separate between hardware devices much like normal MMUs govern software. However, unless this sort of IOMMU device is active, PCI and PCIe hardware is generally capable of transferring data to or from any other connected device, including any area of system RAM. Sometime this can even extend to external interfaces; for example, people have been known to take advantage of the DMA capabilities of the Firewire protocol to read the contents of RAM on an active system.

      In general, non-hotpluggable hardware has been granted the same level of trust as the OS kernel, so no one worried very much about it. IOMMUs were more about protecting against faulty or corrupted software (device drivers) than malicious hardware. However, more and more hardware is hotpluggable these days. Also, some software interfaces are becoming too complex to really trust—consider, for example, the interface to a modern GPU, which must transfer data to and from RAM, and perhaps other GPUs, under the control of code provided by user-level application software (shaders, GPGPU). Without an IOMMU it is up to the driver software to prove that such code is perfectly safe, which is an inherently hard problem.

    In a nutshell, wPCIe enables a PCI Express switch with local and remote components linked by a 60GHz connection. The first applications, which will start sampling next year, will let you connect your laptop to a base station with all kinds of storage controllers, networking controllers, and yes, an external graphics processor.

    I don't know about you, but I don't want to have something operating at 60GHz sitting in my lap, thanks... I'll stick to super-long HDMI or DVI cables if I need to route a monitor signal.

      Yes. As I once pointed out on the Linux kernel mailing list, the FireWire driver enabled external access to physical memory by default, via an un-commented line of code. Only for the first 4GB, though; nobody had updated that backdoor for 64-bit. (There are hardware registers which control the address range for which that feature works. The Linux defaults were to allow 0..4GB-1)

      Whether it is encrypted doesn't matter. I'm a PCI device on your wireless bus. I can access all of your system RAM. The fact that the data is encrypted as it is transmitted to me is irrelevant. Authentication is what's necessary here.

      Refer to the FireWire phys-DMA problem. I can take a firewire-capable video camera, hack the firmware, and create a device that, when plugged into any computer's firewire port, can read and write any value in RAM. Without OS involvement, without anybody even knowing I'm doing it. That's what I'm worried about here.

    I don't know how your company works but, around here, we expect people to show up at roughly the same time every day and...erm...work. Like simultaneously. And, yes, many of our laptop users prefer docking stations to plugging and unplugging power/network/video/keyboard/mouse/monitor every time they come and go.

    There's really no point to it, because you still need another box, a "computer" to wirelessly attach to that has the kick ass graphics and so on..we have that already, called a desktop, and they are cheap now, too. You would still be plopping down your integrated graphics lightweight netbook next to what would basically have to be another full computer, or dang close to it, something that houses the big graphics card and the assorted other stuff it needs to function. You aren't eliminating a box at home, so there's not much of a point to it. If it would completely eliminate a box, sure, but it can't by default, and if it can't, might as well just use your desktop when at home. The freq this proposed system works at only works at extreme close distances, like a few feet at the most, you won't be running this from server two floors away in the basement, so really...just use your ethernet cable then.
