Interrupt latency is a key factor in the performance of a system and well known Linux kernel hacker Robert Love writes about it for the LinuxJournal.

When a very similar set of improvements about interrup latency et al where announced for Longhorn in OS News yesterday, someone wrote:
“gee…they just confirmed what all objective parties suspected…..Windows is not a good Multimedia platform”.
Spelling and grammar checkers in Web Forms NOW!!!
I meant “interrupt latency” and “were announced”, in the above posting.
Interesting in depth piece of text. I can’t wait till 2.6 is being final. My test 8 versoin works great over here and very responsive!
to buggy:
I rather see bad language then all these trolls. You also have to remember not everyone is talkin english nativ.
Plus you got to remember there are different dialects of english to booth, my “hiberno-english” can be a bit different at times from standard english let alone “american-english” 😉
uhh…it is a given that Linux is not a multimedia OS yet….I think every geek from China to Chile knew that.
for some reason, you seem to think that it is not acceptable for Linux, a system that has not really had the chance to develop the higher performance code in the kernel for Multimedia yet due to the catch up they needed to do in kernel technology, yet MS who has been a mainstream OS since day one and has been used for multimedia and even sold on that (media center edition?) should not get blasted for it?
And what’s your definition of “media OS”? I watch movies in Linux all the time. It works, it works well, and I prefer it over Windows Media Player.
The lad that made the comment I quoted raved on about how Linux IS ALREADY a fine multimedia OS and how the fact that Longhorn was getting those extensions implied that Windows never was.
What I wanted to point out with my post was that Linux LACKS the exact same stuff!
P.S (to Anonymous) Multimedia is not just “playing movies” or listening to mp3s.
at least Linux does not sell it self as one.
“P.S (to Anonymous) Multimedia is not just “playing movies” or listening to mp3s.”
So, what IS it?
I’m using Linux as a dedicated audio workstation (see Planet CCRMA http://ccrma-www.stanford.edu/planetccrma/software/ ) and I’ve been having issues with latency due to the crappy and un-configurable bios’ that most mobo manufacturers are shipping. Can someone tell me what this new tech means for existing drivers? Will applications and drivers need to be rewritten to take advantage of this new code?
>So, what IS it?
Realtime multi-track recording and stuff like that.
[eloj] thanks for the clarification.
[debman] Linux is just an Operating System. OSs don’t sell themselves as anything, people (and corporations) do. With this in mind, several parties already touted Linux for use in multimedia setups, either as a DAW or for video editing.
On the other hand, MS does not push Windows as a multimedia platform, except in the toy sense (media center edition etc) . In that reduced sense, Windows performs well.
Macs are still considered the de facto multimedia platform, specially in the states, however a great many of creative professionals have moved to Windows for cheapness.
Just my 0.02 Euros.
DirectShow is what sets Windows apart from Linux in the area of multimedia. Windows has a standardized, modular, graph-based media architecture with widespread commercial support from codec vendors. Linux has… gstreamer, which is not standardized across Linux/Gnome systems and has relatively little support.
