mystery slog entries -- ient xxxxxxxx from 0 to 1, ient xxxxxxx from 1 to 0
I'm getting repetitive entries in the slog:
Jan 01 00:57:05 5 14 0 ient 80f9c3c from 0 to 1
Jan 01 00:57:05 5 14 0 ient 80f9c3c from 1 to 0
I get 15 or 16 entries per second. Any idea where they're coming from?
Thanks,
Gary

What network driver are you running? Are you using io-pkt or io-net?

Running on an Intel platform with the devnp-e1000.so network driver plus another network driver (derived from the sam
ddk package) to implement to implement a private network over the PCIe bus. Jumbo packets are enabled (pagesize=8192,
mclbytes=8192) to improve performance of the PCIe implemented network.

There is no message like this in the e1000 driver, so I guess it could be
somewhere in the stack. ient is an interrupt entry, so do you have an
interrupt service routine in your driver?

RE: mystery slog entries -- ient xxxxxxxx from 0 to 1, ient
xxxxxxx from 1 to 0
I have a multiple CPU system with a PCIe network connection between the Monarch processor and every Endpoint processor.
In my startup code, as I discover CPU modules I execute a mount command to instantiate a driver for each discovered CPU
-- "mount -Tio-pkt -o<slot> libpcielan.so" where <slot> is passed to the driver to inform it which CPU to connect to
and it's also used to generate IP addresses. In my test system I have four CPUs -- the Monarch and three Endpoints so
three "mounts" are executed. After everything is init'ed I have the following ifconfig output from the Monarch CPU:
# ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33192
inet 127.0.0.1 netmask 0xff000000
wm0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
capabilities rx=1f<IP4CSUM,TCP4CSUM,UDP4CSUM,TCP6CSUM,UDP6CSUM>
capabilities tx=7f<IP4CSUM,TCP4CSUM,UDP4CSUM,TCP6CSUM,UDP6CSUM,TSO4,TSO6>
enabled=0
address: 00:17:3c:00:9a:60
media: Ethernet autoselect (1000baseT full-duplex)
status: active
inet 141.121.191.225 netmask 0xffffff00 broadcast 141.121.191.255
PCIe0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 8100
address: 00:01:02:03:00:07
inet 10.1.7.7 netmask 0xffffff00 broadcast 10.1.7.255
PCIe1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 8100
address: 00:01:02:03:00:05
inet 10.1.5.5 netmask 0xffffff00 broadcast 10.1.5.255
PCIe2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 8100
address: 00:01:02:03:00:0b
inet 10.1.11.11 netmask 0xffffff00 broadcast 10.1.11.255
At this point I start getting the "ient xxxxxxxx from 0 to 1, ient xxxxxxx from 1 to 0" entries in the syslog. If I
disable one of the PCIe NICs (ifconfig PCIe2 down) the syslog entries quit. Re-enabling the PCIe NIC causes the syslog
entries to resume.
The Monarch processor is configured with NAT to get from the public wm0 (Ethernet) port to the private network of
Endpoint CPUs. It seemingly all works but I don't understand the syslog entries.
Any ideas?

It's a debug slog from the stack. It's safe to ignore.

Is there any way to disable it? It is persistent and fills the syslog making the syslog unusable for any other logging.

It's a debug slog from the stack. It's safe to ignore.

Not currently. A workaround may be 'io-pkt -t4 ...' where 4
is your number of interfaces. Or 'sloginfo | grep -v ient'.
I'll make a PR to disable it or only spit it out with
io-pkt -v.

Hi Sean
I have asked this question earlier but since you mention about debug traces
of io-pkt here and enabling them thru io-pkt -v
Can you please let me know if there is a way to get io-net debug traces in
systlog? I have tried doing io-net -v but that doesn't seem to help.
Regards
Vineet

RE: mystery slog entries -- ient xxxxxxxx from 0 to 1, ient xxxxxxx
from 1 to 0
Right now my PCIe network driver is run off the timer interrupt (as done in the 'sam' example).

There is no message like this in the e1000 driver, so I guess it could be
somewhere in the stack. ient is an interrupt entry, so do you have an
interrupt service routine in your driver?

Re: RE: mystery slog entries -- ient xxxxxxxx from 0 to 1, ient xxxxxxx from 1 to 0
Is there anyway I can get the source to the PCIe lan implementation that Gary did?
