Soft-Updates for Linux ?

2000-10-01 Thread Robert Redelmeier
I'm wondering if there are any plans to bring Kirk McKusick's "Soft-Updates" to Linux in 2.5 ??? Kirk has recently modified his licence (friendlier). I could only find some noncomittal postings on LKML from 1997. S-U brings considerable benefits akin to JFS for crash protection to *BSD systems.

2.4.0t8 SMP interrupt high latency ?

2000-09-24 Thread Robert Redelmeier
I've been testing out the 2.4.0 kernels as Linus wants. My particular area is looking at SMP interrupt handling trying to write `burnAPIC`. First, the good news: average int overhead measured by `clockwatcher.c` [posted last year] is down from ~960 CPU clocks in 2.2.13 to ~740 clocks in 2.4.

2.4 foreign modules - proc_register() gone ?

2000-09-23 Thread Robert Redelmeier
I'm in the process of migrating my foreign modules to 2.4, and it now appears that proc_register() and proc_unregister() are no longer exported from the kernel. Bug or feature? I know that Linus reserves the right to change interfaces, but I couldn't find any mention in the archives of deleting

SMP APIC spurrious int wierdness

2000-09-22 Thread Robert Redelmeier
In keeping with my other projects, I'm working on `burnAPIC` to test out APIC functionality. I've finally got the APIC interrupt command register working -- in a kernel module, of course. I'm a little behind on kernels -- 2.2.13. I stick in `movl $0x000840D0, 0xE300` and I get a nice sp
