Hello.
I am running FreeBSD-5.4 on a 3GHz P4 with two Intel
fxp NICs running IP forwarding with polling enabled.
For larger packets (e.g. 700 bytes) I am getting
100Mbps throughput port to port.
For min-size packets (64 bytes) I am only seeing
around 60Mbps. Increasing HZ and the polling

You couldn't do 100Mb/s with em on a 100Mb/s line
with min packets, because there are gaps between
packets so its impossible.
Thanks for the detailed reply Danial.
By 100Mbps I mean line-rate: 148809 packets/sec for
64-byte Ethernet frames + IPG and
Hi.
The man page for bus_dma_map_create() says this about
the nsegments parameter:
Number of discontinuities (scatter/gather seg-
ments) allowed in a DMA mapped region. If there
is no restriction, BUS_SPACE_UNRESTRICTED may be
specified.
BUS_SPACE_UNRESTRICTED is #defined as (~0).

Hello. I read a while back about someone working on
supporting sparse kernel crash dumps (dumping only the
active kernel pages to the dump device as opposed to
all physical memory - for machines where the phys mem
is greater than the dump dev space.)
Does anyone know the status of that project?

I am seeing the following problem:

I said:

Then I said:

I didn't realize /bin/sh doesn't close the fd.
Man, I feel so dumb.

Hi,
On 5.4-RELEASE I'm having problems with my AVB card
reader: I often get Synchronize Cache and CSW Tag
errors.
Does anyone have a solid recommendation for a USB
Compact Flash card reader?
Thanks,
Paul.

I have a need to remotely debug an application on a
remote FreeBSD-5.4 machine that is devoid of utilities
and source code.
I previously asked a question about gdbserver, but it
looks like it's not available so I'll ask the more
general question.
I could login in to the remote machine, mount a

gdbserver isn't currently ported for FreeBSD. If
you really need it (as opposed to some other form of
remote debugging), you could probably best get
started
by asking obrien for hints.
Thanks for the info Lowell.
What do you mean by some other form of

Hello, I hope someone can help me.
I am using FreeBSD 5.4-RELEASE and would like to use

The source tree has gdbserver in two places:

There's also a gdb6 in /usr/ports/devel.

I want to run my 5.4-RELEASE system with a serial
console and muted cons. My /boot.config is:
-h -m
The system loads the kernel but during startup the PC
resets. No messages, just a reset.
If I use -h by itself it is fine.
If I use -m by itself it similarly
I have a general question on the status of USB to
serial support in FreeBSD (specifically the ucom and
ftdi drivers).
I need an extra serial port on my system and for
reasons outside the scope of this email I can't just
plug in a PCI card. I'm trying to use USB, but it
seems that ucom is broken
