AMD's New DRM
DefectiveByDesign writes "Remember how AMD said they'd make use of ATI's GPU technology to make better technology? Well, not all change is progress. InfoWorld's Tom Yager reports that AMD plans to block access to the framebuffer in hardware to help enforce DRM schemes, such as allowing more restricted playback of Sony Blu-Ray disks. They can pry my Print Screen key from my cold, dead fingers."
Ok, so AMD aren't doing this because it makes their customers happy. Given the choice between two identically performing chips, one of which restricts your ability to do something, I'd bet most people would choose to get the unrestricted one. Whether that's because they need it not to be restricted, or they think they need it in the future, or they just object to the principle, I'm betting few people would go "Gee, well, this one stops me doing this, so I better get that".
So the only reason AMD is doing this is to pander to the content providers. I wonder, what's in it for AMD. Money? Too simplistic somehow. Can't think what else..... Surely it can't just be because Sony/whoever turned up with a big cheque?
There is nothing interesting going on at my blog
The drooling masses will eat up the slop fed to them so they can watch their DRM'd BluRay edition of Friends and Threes Company.
Trolling is a art,
Disable hardware acceleration of video, and you'll get your printed screens just fine.
From the article: '...ATI's new GPU ... will ship with software that plays movies on Blu-ray discs. The AMD rep ... said that the new chips will "block unauthorized access to the frame buffer." In short, that means an unauthorized party can't save the contents of the display to a file on disk unless the content owner approves it.'
Looks like things are going the same (unhappy) way that the HD-TV did. The web's full of dire stories about people suffering from IBM (Incompatible Bits of Machinery) - most of it shiny new and very expensive.
Imagine Vista on this... *shudders*
How long after release before DVD-Jon or someone else breaks this? Not long. It's just piss of the legit, non-expert user, like most DRM.
"Now I have another reason (other than processor heat) to stay away from AMD."
So I am guessing you used a P3 for all these years and just now upgraded to a Core2Duo.
AMD isn't known for making hot running chips Intel is. I also guess you haven't heard about Intel's trusted platform...
Plus this is just a rumor.
Man you can jump high enough to reach any conclusion you want too.
See my blog http://ilovecookes.blogspot.com/ for light hearted technical information.
You might just be joking, but... Intel is already doing DRM. They're building the features required for TCPA into CPUs now.
This is a non-story really, because this is called "curtained memory", and it is a part of the TCPA specification. TCPA hypervisors can prevent programs accessing memory at a level that you, the user, cannot circumvent. At least, not without breaking the "trusted" nature of your system and stopping some applications from executing.
Given AMD's commitment to TCPA, shared with Intel, ARM, MIPS, IBM and most other processor manufacturers, it is no surprise that they are allowing the GPU memory to be curtained. Your next CPU is defective by design.
Just as audio has the Analog Hole that can never be plugged, framebuffer access restrictions can't continue once it gets out of the DVI cable.
Doing the Right Thing should not be preempted by making a buck.
HDCP.
Why bother.
I think it's fairly obvious that it's about AMD Live! versus Intel's Viiv. Each of those two brands is trying to be the ultimate living room multimedia PC. I think that customers haven't really caught on (why would we... who needs an expensive fully decked-out hot and noisy desktop PC masquerading as a media appliance in their living room?), but they seem convinced that this is where the market is going with or without the consumer. I think the whole media center PC has very little thought for the customer, and this AMD DRM issue highlights that very well.
It's funny how Vista is being hailed as the future for the media PC... I used to be able to watch DVDs perfectly well on my P3 (600MHz, 128 MB RAM) back when it was running Windows 98. But a few years ago I "upgraded" to XP, and now it won't play the same DVDs. It has a very hard time with most video content. But MS (along with AMD and Intel) wants us to believe that we need the next super-shiny version of their software, which gets less and less efficient with each release, in order to keep up with the time and have the media experience of the future. Sure, HD content requires more horsepower to decode and display, but if they didn't keep fattening up the OS, and the player software, and the whole Media Center environment, it wouldn't need that much more horweposer. From my experience, my 2.6Ghz P4 with 2GB of RAM can't even play videos in the Vista Media Center at all. Any PC related living room media devices should be small, quiet, run cool, and be inexpensive, and not have lots of bright lights. But of course all the hardware manufacturers want to push the latest hot, fast hardware... because it's the fastest. They want your attention to be drawn to the PC so you know how cool it is. Lame.
So to make a long story short, AMD, Intel, Microsoft, and all the rest want to cram the media experience down our throats... This seems to me like it's the equivalent of Circuit City's DIVX, only the players involved are much bigger, and mostly working together to make an inescapable dragnet. They want to make their own brands successful (Win MCE, AMD Live! Viiv), and they know that the average consumer doesn't even know why he or she would care about Viiv or Live. So they want to make all PCs move in this direction, and if they can't get the consumers excited about it, they can at least get the content providers excited about it, so they don't have the same fate as DIVX.
Except that the MPAA doesn't manufacture the drives either. Granted, you have a point where movies on HDDVD/BD are concerned, but corporate users can still back up 50+ GB of data without the need for any licensing from the movie industry. In fact, wasn't that how DVD+R came into being in the first place? Companies wanted the storage benefits of DVD-R without having to pay tribute to the "king" that was/is the DVD Forum.
Then again, Dell/HP/Compaq/Gateway do stand to make or lose quite a bit based on "Ooh shiny!" from home/residential/non-corporate users and their desire for HD-everything. Dell, though, should be able to make something of a stand given how many companies I've seen that have massive Dell-based infrastructures in place and doubtless have contracts with Dell for all their kit.
Hmm, I wonder if any media companies are among Dell's corporate customers. That could make for an interesting scenario. Almost mutually-assured destruction. "Want to force your DRM terms on us/our chipmakers? That's funny, we can't seem to find any records of your volume discount or, oh, what's this, even your on-site service agreements."

One poster mentioned that this is essentially covering the framebuffer with the TCPA "curtained memory" spec.
TCPA is and has always been a 2-edged sword that can also be sheathed. I can completely ignore it, I can use it to my own benefit.... or I can surrender control of my computer to The Dark Side.
Is this "hidden framebuffer" the same way? In other words, if I'm not touching protected content can I still access the framebuffer as I wish? Is it also possible that I can use this as extra security? We've taken to encrypting filesystems and swapfiles, and moved from xhost to xauth, it seems to me that the framebuffer could be considered another leakage point. (Won't comment on the difficulty of exploiting.)
Theoretically TCPA can be a good thing, and most of people's fears center around it being required and locked away from the owner. I'm not sure I ever see that being an issue, simply because of implementation and legal difficulties. What I can see is "If you want to use ??AA media, surrender control of your computer, for this boot." As long as I can reboot and have complete control of my own computer, that is.
The living have better things to do than to continue hating the dead.
Oh, I don't know. Ultimately there will be mod chips carrying custom bios etc if things get to that point. People will find a way. The thing about computers is that nothing at all happens without software, and that software can always be diddled. If you are having trouble getting the crowbar in, you just need a better tool to chisel out a gap.

"And God said unto the Israelites
'Blessed is he who protects content
and, ye, shall the masses loath it
but God shall smile upon you,
and bless your blu-ray player
and the copy of Batman Begins
housed within it.' "

I work for a major corporation. Why don't we bother with this DRM sort of thing? The short list:
Often, the truly valuable things in a company are the ideas and business strategies. This is low bandwidth information. The others - such as code, source masks, etc... already have the legal protection afforded trade secrets and copyrights. While it might not be practical to hand copy source code, this kind of espionage is rare and not very valuable. If company A stole company B's source code, company B would probably have a pretty good legal case against company A. However, the case for stealing ideas is a bit murkier and harder to prove.

Implementing DRM functions in the CPU is not cowtowing to Vista, it's responding to the same rights management pressures that VISTA had to accommodate. VISTA's DRM is there to satisfy the demands of the content providers so that Vista can play back DRMed media from those providers. I know you want to blame MS for all the ills of the World, but you'd do better directing your misplaced anger at things like the BluRay consortium which make the DRM demands that Vista meets.
