Hello all,
I want to allocate 120KB of memory thats aligned to 32KB.
I already saw/found the function contigmalloc, now my question is, why
following functioncall never does return with an resulting address, instead
null is returned?
unsigned long *p = (unsigned long*)

Hi,
We're experiencing a kernel hang on a 6.x quad processor Sun amd64
based system. We are able to reproduce it fairly reliably, but the
environment to do so is not easily replicatable so I cannot provide a
simple test case. However, I

My suggestion is to make the your high limit (currently 1 22) MUCH
higher, if possible. Also, getting rid of the 1MB boundary might help.
PS: contigmalloc is on the way out. Please use man bus_dma instead. For
an example see:

sorry for the cross-posting, but not realy sure where this
belongs.
Linux just incorporated this, so I was wondering if anything
along this lines is being done/concidered for FreeBSD?

I've seen that Roman asked about this few months ago but it seems nobody
answered. Are there plans to support or people working on integrating
gcc pre-compiled headers to buildworld/buildkernel?

On a computational chemistry list I subscribe to there is a
current thread about multi-cpu systems needing to have the cpu
frequencies synced (this is in a Linux context). This is
evidently not just having the cpus running at nominally the same
frequency but
frequency but something else in addition. A posting in the
thread said variations less than 0.1% were not problematic.
However, the poster said it was an issue in a dual cpu, dual
core system he had set up.
Why would application code care about CPU frequencies?

I'm using kqueue() with a EVFILT_WRITE to send udp packets over a
gigabit interface (the job here is to stress test DNS servers). I'd
like to send packets at wire rates, but somehow the EVFILT_WRITE is
always triggered and I'm dropping a lot of packets on the floor.
Is there a way (preferably
Thank you for the pointers. It sounds like reading data back from the
parallel port is not a common thing to do, although I thought parallel port
projects might have done this. Then I realized that most PIC programmers,
parallel port displays, etc. usually only receive data, not send it back
No, I didn't try that but I certainly will now. I wasn't sure you
could just cat the port and read the data back. I will let you know
how this works.
Well, you should certainly try it, but don't count on it: Daniel says
that lpt returns only printer status (BTW, this means full 5 bits,

Well, the FD will always be ready for write (and it can tell you how
much data you -can- write as part of the message.)
The standard way around it is to register w/ EV_ONESHOT and only get
one event back when its ready for writing; but then you have to
re-register after you've filled the TX
