LWN: Comments on "The Ottawa Kernel Summit, Day Two"

High resolution posix timers?

dank — 2002-06-27T07:54:29+00:00

I haven't heard anything about the high-resolution posix timer
patch going into 2.5. Surely that's going to be one of the
features that goes in before the freeze...

Excellent summary! Thanks for the work that went into making such a good summary of the details in a fashion that was VERY easy to read and understand.

Names on the photo?

Making an annotated photo, like last year's, is high on my list. I'll not be able to do it, though, until I'm back home and in front of a good, high-resolution screen - my ancient, windup laptop just isn't up to that sort of gimp work. So, next week at best. Sorry...

LSM network performance clarification

jamesm — 2002-06-26T11:30:57+00:00

The 20% figure mentioned in the story refers to testing that was done with
SELinux loaded on top of LSM . The overhead for LSM itself is in the
5-7% range. Note that this is for gigabit ethernet; there is no noticable
performance hit with 100Mbps networking.

I'd really like to be able to put names to the people in the pictures.

Names on the photo?

nicku — 2002-06-26T02:14:31+00:00

Thank you for an interesting article. I especially liked the photo from last year with people's names on it; this photo is very good too. Does anyone have the knowledge/time to annotate this photo with the kernel team's names?

I/O Completion Ports

dank — 2002-06-26T01:22:41+00:00

FWIW, "I/O Completion Ports" are just a way of getting completion notification from asynchronous I/O requests. Once the kernel supports AIO, it will probably also support completion ports. Whether it will support exactly the I/O Completion Ports windows programmers are familiar with is another question; the scheduling policy associated with Windows IOCP's may be protected by a Microsoft patent.
