Intel has released open-source software to give Linux full-fledged support 
for 3D graphics, a move that could give its graphics chips a leg up over 
rivals.

Right now, Linux users typically rely on proprietary driver software if 
they want to use graphics acceleration chips and hardware to improve 
graphics performance--to speed up displays of 3D tanks in a battle video 
game, for example.

But this proprietary approach poses ethical, legal and practical problems. 
Intel sees the open-source move as a way to attract customers to its 
graphics products--such as its upcoming 965 Express chipset--and give it an 
advantage over rivals ATI Technologies and Nvidia.

"Having open-source drivers gives us a big edge in this market," said Dirk 
Hohndel, chief technologist of Intel's Open Source Technology Center. The 
software, available at a new Web site, is already being integrated with 
relevant open-source projects, he said.

Intel's effort reflects the curious intersection of technological, legal, 
social and business motivations that operate in the open-source realm. By 
participating in the collaborative programming movement, Intel builds ties 
with outside developers and open-source fans. On the other hand, it 
relinquishes some control over the software and forgoes the possibility of 
keeping some coding secrets.

And one politically important ally, the Free Software Foundation, was 
delighted with Intel's move.

"It's a very important step in the evolution of the industry," said 
foundation attorney Eben Moglen, who is overseeing a revamp of the General 
Public License (GPL) that governs the Linux kernel. "The move that Intel 
has taken, toward making better interoperability with free operating 
systems by abandoning secrecy, is the sign of a new competitive approach."

More practically, Intel's move is well-timed to dovetail with Red Hat and 
Novell projects to build fancy graphical interfaces into Linux. The new 
interfaces, often referred to as "bling" and "eye candy," require 3D 
acceleration.

Although enthusiasts who favor the glitzy interfaces may benefit from 
Intel's move, it's not clear whether there will be a benefit for the 
chipmaker itself. For now, engineering customers using Linux for high-end 
graphics work, such as mechanical design, rely on add-in graphics cards, 
not on Intel's integrated graphics. And gaming--the big market for 3D 
graphics--uses Microsoft Windows almost exclusively.

Intel has a major part of the overall graphics market; it shipped the 
graphics chips for 40 percent of PCs in the second quarter of 2006. ATI's 
share was 28 percent, and Nvidia's, 20 percent, according to research 
analyst Jon Peddie.

Repercussions
Peddie thinks it unlikely ATI or Nvidia will release open-source drivers as 
a result of Intel's move. Details of the hardware interfaces for graphics 
chips are the "family jewels...and expose how the chip itself works," he 
said. "Nvidia doesn't want ATI to know that, and vice versa."

ATI didn't immediately comment on its plans, but Nvidia said it wouldn't 
change its approach as a result of Intel's move. "At this time, it does not 
make sense for us to open-source our graphics drivers," Nvidia spokesman 
Brian del Rizzo said. "We are confident in our ability to provide our 
customers with the best graphics solutions possible."

But Michael Larabel, who runs the Phoronix Linux graphics site, believes 
there could be repercussions.

"Intel's move may cause Nvidia and ATI to rethink open-sourcing some areas 
of their drivers, improving the level of support, or funneling more 
resources to their Linux department," Larabel said.

And it also will certainly be watched closely at Intel's main Silicon 
Valley competitor, Advanced Micro Devices, which in July announced plans to 
acquire ATI for $5.4 billion. AMD has worked closely with open-source 
programmers on several occasions, in adding Linux support for 64-bit x86 
chips and for AMD's virtualization technology, for example.

"Ideally, if AMD is able to realize the potential of open-source ATI Linux 
drivers, we could very well see GPL...drivers within the next few years," 
Larabel said.

Margaret Lewis, AMD's director of commercial solutions, wouldn't be pinned 
down. "It is hard to speculate if open-source drivers can give a 
competitive advantage over Intel and Nvidia," she said. "Open-source 
drivers could help ease the difficulty of dealing with proprietary drivers 
with Linux. However, proprietary drivers often provide better optimizations 
or support more features. Having both types of drivers available gives 
customers a choice of which approach they want to take."

Open-source advocates have expressed several objections to proprietary 
drivers. These often stop working if a computer user updates Linux, forcing 
the computer user to reinstall the driver. Also, some believe the GPL 
doesn't permit proprietary kernel modules to be plugged into Linux.

No. 2 Linux seller Novell recently banned proprietary Linux modules, though 
it streamlined the process by which people can download them from their 
creators.

Timed for new chipset
Intel released the graphics software just before the LinuxWorld Conference 
and Expo, which begins Aug. 15. But the main impetus for the open-source 
driver timing was that Intel needed to support its 965 "Broadwater" 
chipset. The chipset is used in conjunction with Intel's new Core 2 Duo 
"Conroe" processor and is being released next week, Hohndel said.

"We're releasing drivers before the hardware gets released, which is a nice 
change of pace," he said.

Indeed, after Intel's release of open-source Centrino wireless-network 
drivers lagged Windows by more than a year, Intel pledged to make its Linux 
support simultaneous.

Intel has four programmers working on the driver project as well as five 
people testing the code, Hohndel said. Among the programmers is Keith 
Packard, formerly of Hewlett-Packard and Suse Linux. Packard is a major 
figure behind the X.org software that handles basic 2D graphics for Linux.

Intel will maintain the project, but hopes for outside contributions as 
well, Hohndel said. The work affects three components: X.org, the Mesa3D 
software that handles 3D graphics, and the Linux kernel software that 
mediates between the two other components, Hohndel said.

One open-source expert at HP favors Intel's approach. "All things being 
equal, we will choose silicon for which we can get open-source drivers 
every time," said Bdale Garbee, chief technologist of the open source and 
Linux group at HP.

Proprietary drivers means more work for HP when supporting Linux, Garbee 
said. When software support for particular hardware isn't built into the 
Linux kernel, "It gets progressively more difficult for a company like HP 
to do the recurring engineering work associated with keeping fresh driver 
versions for new kernels available," Garbee said.
