I've finally learned enough forth to put together a diff to implement some
nextboot functionality in the loader.
Basically, the loader peeks into the first line of /boot/nextboot.conf to
see if nextboot_enable=YES is there. If it is, it reads the entire

This was -stable- but it's really a hacker's question.
I really am *not* much of an i386 weenie and I'll have to admit that I don't
fully understand the interrupt mask scheme and I ran into a troubling problem
.
I was running some very extensive tests on a dual processor (but not SMP
itself (since it likes to). FreeBSD does not have code to handle
assigning PNP resources, or at least code that works well :) (There is the
PNPBIOS kernel option, but I'm not sure that works anymore.)
The PNPBIOS option just implements another accessor method; resource
allocation is a
For drivers which must be active in the boot path, it is
generally necessary to embed the firmware in the driver as
data. This is what FreeBSD does for the Adaptec SCSI
drivers.
For drivers that need to be active after boot time, but before
the mi_startup() is complete, you can load the
Could anyone please tell me if there's any way to find out which
device the system booted from in a user application. The loader
sets loaddev and currdev vars, but I see no way to transfer them to
the user environment.
kenv(8) allows you to read the kernel/loader environment.
I respect the gcc effort, but if icc is as good as it is told to be
then it could supersede (at least in intel community) gcc.
What is the general sentiment and the will for cooperation about
porting icc to FreeBSD?
I doubt that porting will be necessary; I've watched another developer

At any rate, my key point is that the splitting should be invisible, and

Ok, attached is the path, which does exactly what described. Please
review and if there are no objections I would like to commit it
shortly, so that our re@ team would be
hw.busfrequency = 133326902
Not typically obtainable. And which bus?
hw.cpufrequency = 66700
Should be obtainable on Alpha and Sparc, and calculable on x86 (though it
will probably have to be calculated at the time the sysctl is read, since
it's variable).
hw.cachelinesize = 32
Please review attached patch, which adds long overdue feature to our

Ok, sounds reasonably. I'll try to reimplement the feature this way.
Thank you for suggestion.
Thanks for doing the real work!

I'd like to develop a kernel module for FreeBSD, able to read write
directly to VGA text-mode screen buffer. I know that this buffer is located
at 0xB8000 in physical address space. But in kernel I must address it using
kernel virtual address space.
Thus, the question is: how can I

Is there some quick, down dirty way of assessing the bus-speeds of PCI

Unfortunately, no. The Yahoo! folks have worked on some old SMBios code

One (very nasty) already exists in libstand. There was a very small

I have been trying to port a driver I had written on NetBSD to FreeBSD.
On NetBSD the driver functions without incident, On FreeBSD, after a time
the whole system locks up.
Sounds like resource starvation of some sort.

Is there any easy way to read the contents of a system BIOS from userland?
No. Most modern BIOS code is paged, compressed and in some cases
encrypted.

nothing generic. I'm trying to write a program that will dump
Use isprint() on the entire string; this will give the desired result in

a security measure).

I like it, but there are a few problems.
