Stale[edit]

Moreover, debugging device drivers is a difficult skill as it often involves monitoring hardware itself - which by definition behaves in a non-deterministic way.

Um. Hardware is nondeterministic? Am I missing something here, or is that a bit on the wrong side? - Jkominek 04:00, 23 October 2002 (UTC)

yeah, its not like we're writing device drivers for brains or anything. Jeeez. Hfastedge (talk • contribs) 04:14, 23 October 2002 (UTC)

Yeah, calling clocked hardware non-deterministic is wrong in my opinion. May be it was intended to mean poorly fabricated. Wk muriithi (talk • contribs) 21:18, 1 March 2005 (UTC)

Well, the question about the level of determinism of the physical reality is open, to my knowledge. However, the writer probably meant something else. The outside world is much less controlled than the world of memory locations and registers. And now that I am here commenting this pretty important subject, please tell me if you really think this Device drivers can be abstracted[by whom?] into logical and physical layers is really weasel words. In my opinion, it is of course nice to tell the audience who invented layering device drivers, but on the other hand, given it is so logical step it does not have to be some particular person or institution at all. I start to fear I see the sentence Pike is a fish and then someone asks by whom?. 193.110.109.30 (talk) 06:36, 16 October 2009 (UTC)

Unless operated by a robot a keyboard is definitly non-deterministic.. And if network cards worked 100% deterministicly we would have faster than light communication simply by calculating the next packet before it actually runs thru the tubes.. --TiagoTiago (talk) 19:58, 15 June 2012 (UTC)

File system drivers[edit]

I find it strange to talk of file systems managers as drivers, since 'A device driver [..] is a computer program that enables another program [..] to interact with a hardware device. By extension, you could potentialy call any service a driver.. —Preceding unsigned comment added by 193.49.124.107 (talk • contribs) 15:11, 4 October 2005

FSDs are developed using the same methodologies and kits as 'device' drivers, at least in the Microsoft world. In fact, the filesystem kit is a superset of the driver development kit. -- dispensa (talk • contribs) 04:00, 14 October 2005 (UTC)

I actually came here also looking for information about non-hardware drivers (for example, some security applications on the Windows platform). This article should definitely cover this category, even if only to say it is an incorrect use of the term. 187.10.177.188 (talk) 23:25, 23 October 2013 (UTC)

Link Cleaning[edit]

I just cleared most of the spam I want some else to look at the remaining two links. Please let me know if they don't belong. I'll be back in few days to see if any of the deleted references magically return.--Phatom87 06:07, 1 December 2006 (UTC)

N-bit Driver[edit]

Depending on the specific computer architecture, drivers can be 8-bit, 16-bit, 32-bit, and more recently, 64-bit. This corresponds directly to the architecture of the operating system for which those drivers were developed. For example, in 16-bit Windows 3.11, most drivers were 16-bits, while most drivers for 32-bit Windows XP are 32-bit. More recently, specific 64-bit Windows versions have required hardware vendors to provide newer 64-bit drivers for their devices.

I don't think one can classify the drivers are n-bit drivers. Only machines and OS can be classified as such. What does a 16-bit driver mean? Does it mean that the driver is accessing the registers on the device as 16-bit words? In fact, I have seen devices on machines with 32 bit words, that can be accessed only as 16-bit words. So, the 'bit length' of the driver depends on the peripheral and the machine. Any way, I think this is not a very good way to classify the drivers. I think we should remove this line. —Preceding unsigned comment added by Avkulkarni (talk • contribs) 10:48, 17 April 2007

I agree. Speaking as a kernel engineer, that paragraph made me cringe. Basically it means that drivers should be implemented using the same instruction set as their host kernel. Well, duh. It might perhaps be worth changing it for an explanation that x86 supports different instruction sets of varying word size, and that while thunking can be used to allow a driver written for one instruction set to be used in a kernel for another, it is generally considered best to avoid this process.

Difference?[edit]

What's the difference between a device driver and firmware? Maybe someone should consider adding that as a section, because I'm confused and others may be as well. Ryan Salisbury 21:03, 2 July 2007 (UTC)

Device driver is like a dual-language dictionary to help you tell a foreign hairdresser how you want your hair done, firmware is like a hairdressing course. --TiagoTiago (talk) 20:09, 15 June 2012 (UTC)
