NetBSD 4.0, PCIe Intel Pro/1000 PT support and Core 2 Duo speedstep support

Hi there,

I'm pleased to say that the weird corruption issue that I was having appears to have gone. I'm still not sure if it was just the old Deathstar disk playing up, or the onboard Realtek NIC causing problems. I'm now using neither of those, and it's been fine for a couple of days so far.

My first question is regarding speedstep support. I thought this was now supported, but it doesn't appear to be working for me. I have "options ENHANCED_SPEEDSTEP" in the kernel.

`estd` just throws this at me

(root@homeserver:ttyp0)-(~)# estd
estd: Cannot guess CPU-scaling technology. (maybe you are missing some kernel-option?)

There is also nothing in dmesg regarding speedstep

Perhaps it is something to do with those last 4 lines?

My second question is regarding support for an Intel Pro/1000 PT PCIe NIC. Specifically Before I waste my money, can anyone tell me for certain that these are working? :)

Other than that, I am impressed!

Network transfers are now at the full 10MB/s where before it maxed out at around 6MB/s, with same NIC.

I can't quite remember now, but RAIDframe RAID1 hard disk performance may have gone up by about 20MB/s too. I'm sure a `dd if=/dev/rraidXd of=/dev/null bs=16k` before was 30MB/s ish, and now it's 50MB/s ish, with the same disks. Whether those numbers mean anything is a totally different matter though I suppose. :)
