i think it might be trying to tell you that the target directory
$INSTALL_FW_PATH doesn't exist and is a prerequisite to actually
perform the action.
it complains about atmsar11.fw first because it just happens to be the
first firmware that needs to be installed.
/scratch/chas/net-next relax.53% ls -ld /tmp/funk
ls: cannot access /tmp/funk: No such file or directory
/scratch/chas/net-next relax.54% make INSTALL_FW_PATH="/tmp/funk" firmware_install
make[1]: *** No rule to make target `/tmp/funk/./', needed by `/tmp/funk/atmsar11.fw'. Stop.
make: *** [firmware_install] Error 2
/scratch/chas/net-next relax.55% mkdir /tmp/funk
/scratch/chas/net-next relax.56% make INSTALL_FW_PATH="/tmp/funk" firmware_install
INSTALL /tmp/funk/atmsar11.fw
MKDIR /tmp/funk/e100/
INSTALL /tmp/funk/e100/d101m_ucode.bin
INSTALL /tmp/funk/e100/d101s_ucode.bin
INSTALL /tmp/funk/e100/d102e_ucode.bin
...
i am somewhat concerned that it appears to have an extra set of "'s in
the path as well. how are you passing in INSTALL_FW_PATH? i can get
the same result with:
/scratch/chas/net-next relax.57% make 'INSTALL_FW_PATH="/tmp/funk"' firmware_install
make[1]: *** No rule to make target `"/tmp/funk"/./', needed by `"/tmp/funk"/atmsar11.fw'. Stop.
make: *** [firmware_install] Error 2
but it would be wrong to do it this way.

Sorry. My mistake. In this case it seems that sleep functions can
be called from thread_fn, since interrupt line is disabled globally.
And nothing bad will happen if you know that device can be
blocked for relatively long time.

Its not csb1724 specific; I've merged it into
kirkwood: Add a clock setup helper for mv643xx ethernet.
and renamed it to:
kirkwood: Add fixups for DT based mv643xx ethernet.
As this described its purpose better. Hopefully in time, we can

In fact my first motivation was to integrate Debian, Fedora and
other distro updates in to single source. I sometimes look
into their sources and integrate some of their changes.
Anyway, I am happy if distro changes are posted and discussed.

I was under the impresion that iputils had been handed over from Alexey
to Hideaki YOSHIFUJI. The fork at linux-ipv6.org certainly doesn't
appear dead. I count 12 commits this year to the repository visible at
http://www.linux-ipv6.org/gitweb/gitweb.cgi?p=gitroot/iputils.git;a=summary
It's not exactly a screaming fast pace, but it's something.
There are several (mostly relatively minor) bugs that have been fixed in
the Debian packages (of which I'm the maintainer). There's another
assortment of patches in the Debian bug tracker that haven't yet been
merged in. I imagine Fedora and RHEL have a collection of similar
modifications. So I suspect that iputils really isn't dead, but it's
just that nobody's bothering to push changes back upstream. I'm more
than happy to start doing so.

iputils has been unmaintained for at least 2 years.

If you don't run izcoordinator with -d, it won't set the PAN and/or

izcoordinator -i wpan0 -d 1 -s 2 -p 777 -c 11 -l lease

It's not worth it to do sync DMA. The performance is terrible.

Yes that is something that needs to be addressed when we get async DMA support working.

Yes, they use this interface, but split 'memcpy_toio' to two operation:
1. setup dma
2. wait/poll for the dma to finish.
So maybe it need to provide a generic function 'tx' for different hardwares.
If async_tx is available, it's much better than this 'sync dma/memcpy'.
One problem with async_tx is, it can't detect memcpy error.
If the remote ntb goes down when async_memcpy is in operation, async_tx
will trigger an oops.

* Build failure when installing atm ambassador firmware
From: Shea Levy @ 2012-08-01 1:59 UTC (permalink / raw)
To: Chas Williams; +Cc: netdev, linux-kernel@vger.kernel.org
Hello,
When building with
MODLIB=/nix/store/ghx6s9hnk9irim7c7f63zrxqiv6xjh3w-linux-3.5/lib/modules/3.5.0
and
INSTALL_FW_PATH="/nix/store/ghx6s9hnk9irim7c7f63zrxqiv6xjh3w-linux-3.5/lib/firmware",
building Linux 3.5 with CONFIG_ATM_AMBASSADOR=m fails with:
"make[2]: *** No rule to make target
`"/nix/store/ghx6s9hnk9irim7c7f63zrxqiv6xjh3w-linux-3.5/lib/firmware"/./',
needed by
`"/nix/store/ghx6s9hnk9irim7c7f63zrxqiv6xjh3w-linux-3.5/lib/firmware"/atmsar11.fw'.
Stop."
My .config is after the message. Note that while I believe this should
work even with the unusual MODLIB/INSTALL_FW_PATH, a quick Google search
replacing those paths with the normal /lib shows others have the same
error. The error seems to be due to make version, I'm using GNU Make 3.8.2.
Regards,
Shea Levy

It only happens for routes like 255.255.255.255 and for those who
use tclassid on input.
Everything else is cached in the existing FIB trie entries.

I echo'ed your original comments on this to Intel Legal and am waiting
on a response. I 100% agree, but I need their signoff first.
It is worth noting that this version of the license is already in the
kernel in numerous other drivers:
drivers/sfi/*
drivers/scsi/isci/*
drivers/dma/ioat/dma_v3.c
drivers/net/wireless/iwlwifi/*
drivers/net/wireless/iwlegacy/*

What about systems will full 1M route table?
I wonder if doing rbtree here would make the search faster?

I think Eric Dumazet and I have dealt with all of the known routing
cache removal fallout. Some other minor fixes all around.
1) Fix RCU of cached routes, particular of output routes which
require liberation via call_rcu() instead of call_rcu_bh().
From Eric Dumazet.
2) Make sure we purge net device references in cached routes
properly.
3) TG3 driver bug fixes from Michael Chan.
4) Fix reported 'expires' value in ipv6 routes, from Li Wei.
5) TUN driver ioctl leaks kernel bytes to userspace, from
Mathias Krause.
Please pull, thanks a lot.

How will this module be auto-loaded by a distro? You need some way to
detect this device on the "bus" right? What is that method? And why
isn't it hooked up to the "traditional" method the kernel uses to
determine this?
Don't expect distros to just always load this module, that's not going
to work, sorry.
