Does "makeoptions WITH_CTF=yes" actually work?
I read the UPDATING entry that accompanied r206082 and added WITH_CTF=yes to my kernel config, hoping to get CTF information in the kernel and all modules. No luck. It appears that NO_CTF remains set to 1 inspite of the undef NO_CTF in various .mk files and ctfconvert never runs. Can anyone confirm whether r206082 works as advertised or not?

Can you also try a "makeoptions WITH_CTF=yes" in your KERNCONF
and see if the results are as expected? How was r206082 tested? I'm
trying to figure out the differences, if any, between your build setup and
mine.

I got rid of the @ in front of all the CTF commands in all the .mk files. I
could see that NO_CTF was 1 and so the ctfconvert after || wouldn't
run.
[ -z "${CTFCONVERT}" -o -n "${NO_CTF}" ] || ${CTFCONVERT} ${CTFFLAGS} ${.TARGET}
[ -z "ctfconvert" -o -n "1" ] ||
Do you see anything different if you remove all the @'s?

I tried this:
# ctfdump /usr/obj/usr/src/sys/GENERIC/kernel
/usr/obj/usr/src/sys/GENERIC/kernel does not contain .SUNW_ctf data

Have you or anyone else ever used buildkernel successfully with "makeoptions WITH_CTF=yes" in the conf file? Something as simple as this does not work for me: - pristine sources in /usr/src, empty /usr/obj, no /etc/make.conf, no /etc/src.conf - add "makeoptions WITH_CTF=yes" in sys/amd64/conf/GENERIC - make buildkernel in /usr/src The result is a kernel without CTF information.

Your patch works for me, thanks. There is just one more problem with the CTF
generation that needs to be fixed:
http://lists.freebsd.org/pipermail/freebsd-hackers/2009-April/028244.html
While you're here can you take a look at the patch in that email too?

My personal opinion is that all ctfconvert and ctfmerge commands should show up in the output of make iff they run. I believe that used to be the case before r206082.

Your panic must be while using netmap's emulation mode on top of cxgb. Try modifying check_pkt_coalesce() in the driver to always return 0 and see if that avoids the panic.

It is documented in build(7) too: MAKEOBJDIRPREFIX Defines the prefix for directory names in the tree of built objects. Defaults to /usr/obj if not defined.

Andriy, The patch is also available in D3727. I downloaded the raw diff from there, applied it to $PORTS/devel/gdb, and built it as a port (with the KGDB support option enabled of course).

Doesn't have to be devd. Could be any automated script running
ifconfig. Leave this running and see if ifconfig is ever called with
(cxgbe|cxl|cc) as parameter. If it is then that's what's loading
cxgbe(4) automatically.
dtrace -n 'proc:::exec-success /execname == "ifconfig"/
{trace(curpsinfo->pr_psargs);}

I have one of these X8DT6 systems. It has grub2 as the primary boot
loader which then loads zfsloader. Many weeks back I updated the BIOS,
grub, and FreeBSD and ran into a similar problem -- zfsloader would
start, print a few messages, and then the system would reboot. I
tracked it down to the int 0x13 call (with eax=0x4800) in bd_int13probe.
It would walk past the end of the edd_params structure and corrupt the
return address on the stack. I worked around it by padding edd_params.
I was planning to debug it further to find out which of the 3 things
that were updated caused the problem but Other Things(tm) came up. See
if this works for you too:

If the installer itself can come up without the NIC driver it should be able to load any NIC driver KLD it wants and then reach the "install media" (NFS, FTP, etc.) over the network.

A 40Gb link does not limit a single transfer to 10G. For example, on FreeBSD all common bandwidth benchmarks reach 40GbE line rate with a single TCP connection at mtu 1500. If a single transfer were limited to 10G you'd need 4 connections to get there. The physical signalling is over four lanes so it's easy to split a 40G link into four separate 10G links. But when running as a 40GbE (this is the usual case) the hardware will combine all the lanes into a single 40G data stream, and you get to use all of the bandwidth.

I have quite a bit of code that does this stuff but I haven't pushed it upstream or even offered it for review (yet). cxgbe(4) hardware does throttling and traffic pacing too, but it's not limited to TCP, and it can do it per queue or per "flow" -- you can limit a tx queue or an individual flow to a packet-per-second limit or a bandwidth ceiling; this works for both plain NIC (TCP, UDP, whatever), as well as stateful TCP offload). For TCP (NIC or TOE) the chip can even rewrite the TCP timestamp to account for the extra time that the chip/driver held the packet because it was asked to slow down a flow. The per queue stuff is handled via a driver-specific tool (cxgbetool). For per-flow throttling my implementation adds a new sockopt (SO_TX_THROTTLE) that lets an application specify a throttle rate for a socket. The kernel allocates a "flow identifier" for each such socket and tcp_output (or udp_output, ..) will attach an mbuf tag containing this identifier and throttling parameters to each mbuf that it pushes out. Drivers for hardware that can throttle traffic look for this tag, the rest ignore it. - cxgbe(4) registers itself as a "flow throttling provider" with the kernel when it attaches to the chip. It tells the kernel how many flows it can handle and the range of rates it can handle. - setsockopt(SO_TX_THROTTLE, rate) makes the kernel allocate a unique identifier for the socket. This is *not* related to the RSS flowid at all. If a listening socket has SO_TX_THROTTLE, all its children will inherit the rate limiting parameters but will each get its own unique identifier. The setsockopt fails if there aren't any flow throttling providers registered, - tcp_output (and other proto_output) routines look for SO_TX_THROTTLE and attach extra metadata, in the form of a tag, to the outgoing frames. - cxgbe(4) reads this metadata and acts on it.

Here is the kernel side of the patch: http://people.freebsd.org/~np/flow_pacing_kern.diff The registration parameters and the throttling parameters are probably cxgbe-centric, because that's what it was written for. We'll need to tidy up those structs certainly. And I'd like to add pps constraints to the throttling parameters (all it does is bandwidth right now).

This is the reason cxgbetool (and not ifconfig) has a private ioctl to frob cxgbe's per-queue rate-limiters. I did not want to add ifnet ioctls that in reality were cxgbe only. Ditto for i2c ioctls. Now we have multiple drivers with i2c and melifaro@ is doing the right thing by promoting these private ioctls to a standard ifnet ioctl. Have you considered a private mlxtool as a stop gap measure? To summarize my take on all of this: we need a standard ratectlreq structure, a standard way to associate an inpcb with one, and a standard way to pass on this info to if_transmit. After all this is in place we could even have a dummynet-ish software layer that implements rate limiters when the underlying hardware offers no assistance.

What happens when the outbound route for an inpcb changes? This is managed separately by a daemon or such. The problem about using the "inpcb" approach which you are suggesting, is that you limit the rate control feature to traffic which is bound by sockets. Can your way of doing rate control be useful to non-socket based firewall applications, for example? You also assume a 1:1 mapping between "inpcb" and the flowID, right. What about M:N mappings, where multiple streams should share the same flowID, because it makes more sense? You're right that an inpcb based scheme won't work for non-socket based firewall. inpcb represents an endpoint, almost always with an associated socket, and it mostly has a 1:1 relation with an n-tuple (SO_LISTEN and UDP sockets with no default destination are notable exceptions). If you're talking of non-socket based firewalls, then where is the inpcb coming from? Firewalls typically keep their own state for the n-tuples that they are interested in. It almost seems like you need a n-tuple -> rate_limit mapping scheme instead of inpcb -> rate_limit. Regards, Navdeep - The in_ratectlreq structure that you propose is inadequate in its current form.
