D drivers discovered by Rapid.It is speculated that this bug has existed since 2.Nvidia have denied this, asserting that the issue was only communicated to them in July 2.X. Org, not in Nvidias driver.Another problem with binary drivers is that they often do not work with current versions of open source software, and almost never support development snapshots of open source software e.Nvidias or ATIs proprietary drivers with a development snapshot of an X server or a development snapshot of the Linux kernel.Furthermore, features like kernel mode setting cannot be added to binary drivers by anyone but the vendors, which prevents their inclusion if the vendor lacks capacity or interest.In the Linux kernel development community, Linus Torvalds has made strong statements on the issue of binary only modules, asserting I refuse to even consider tying my hands over some binary only module, and continuing I want people to know that when they use binary only modules, its THEIR problem.Another kernel developer, Greg Kroah Hartman, has commented that a binary only kernel module does not comply with the kernels licensethe GNU General Public Licenseit just violates the GPL due to fun things like derivative works and linking and other stuff.Writer and computer scientist Peter Gutmann has expressed concerns that the digital rights management scheme in Microsofts Windows Vista operating system may limit the availability of the documentation required to write open drivers as it requires that the operational details of the device be kept confidential.In the case of binary drivers there are also objections due to free software philosophy, software quality and security concerns.There are also concerns that the redistribution of closed source Linux kernel modules may be illegal.By choice, the Linux kernel has never maintained a stable in kernel Application binary interface.There are also some concerns that proprietary drivers may even contain backdoors, like one that was found in Samsung Galaxy series modem drivers.From a hardware developers perspectiveedit.In the future lib.GL fglrx glx could use the lib.DRM of the radeon open source driver instead of the proprietary binary blob, since most of the investment is in the user space driver.When applications, such as a 3.D game engine or a 3.D computer graphics software, shunt calculations from the CPU to the GPU, they usually use a special purpose API, like Open.GL or Direct. 3D, and do not address the hardware directly see also Cell microprocessor.Because all translation from API calls to actual GPU opcodes is done by the device driver, it will contain a considerable amount of specialized knowledge and be the constant object of optimization.This takes time and involves significant financial investment.Thus leakage of device driver source code, whether published under a free license or not, can give competitors an advantage especially newcomers to the business of graphic acceleration, who would gain a considerable amount of know how without bearing the costs of developing that knowledge.The desktop computer market was for a long time dominated by PC hardware using the x.GPUs available for the PC.With only three major competitors, Nvidia, AMD and Intel, the main competing factor was the price of hardware and raw performance in 3.D computer games which is greatly affected by the efficient translation of API calls into GPU opcodes.The display driver is an inherent part of the graphics card, as is the video decoder, hardware designed to assist in the calculations necessary for the decoding of video streams.As the market for PC hardware has been dwindling, it seems highly unlikely that new competitors will enter this market.Thus it is unclear how much more know how one company could gain by seeing the source code of the drivers of the other companies.The mobile sector however, presents a different situation The functional blocks i.ASIC, the 3. D acceleration ASIC, the 2.D acceleration ASIC, Video decoding and Video encoding ASIC are separate SIP semiconductor intellectual property blocks on the chip, since hardware devices vary substantially.For example, some portable media players require a display driver that accelerates video decoding, but do not require any sort of 3.D acceleration. The development goal is not only raw 3.D performance, but also system integration, power consumption and 2. Lelouch Of The Rebellion R2 Special Edition Zero Requiem .
