Here is a tree of patches against your 2.6 git tree that adds the
drivers/staging/ directory and related infrastructure.
The infrastructure is:
- add TAINT_CRAP to the kernel and the module build tools
- add MAINTAINERS file entry for this pile of crap
The drivers we have for the staging/ directory in this patch series are:
- USB/IP drivers
- echo cancellation driver (used by mISDN and Zaptel)
- eth131x network driver
- slicoss network driver
- sxg network driver
- me4000 data collection driver
- go7007 video capture driver
- wlan-ng prism2 usb driver
- w35und wifi driver
There are also follow-on patches by individuals cleaning up some of the
problems in these drivers that have kept them out of the main kernel
tree so far.
All of these drivers are self-contained in their respective
subdirectories, touching no other kernel code at all. There are TODO
files in the directories detailing what is needed to be done to clean up
these drivers to get them merged into the main tree.
Please pull from:
master.kernel.org:/pub/scm/linux/kernel/git/gregkh/staging-2.6.git/
Patches will be sent as a follow-on to this message to lkml for people
to see.
thanks,
greg k-h

From: Greg Kroah-Hartman <gregkh@suse.de>
We need to add a flag for all code that is in the drivers/staging/
directory to prevent all other kernel developers from worrying about
issues here, and to notify users that the drivers might not be as good
as they are normally used to.
Based on code from Andreas Gruenbacher and Jeff Mahoney to provide a
TAINT flag for the support level of a kernel module in the Novell
enterprise kernel release.
This is the kernel portion of this feature, the ability for the flag to
be set needs to be done in the build process and will happen in a
follow-up patch.

From: Greg Kroah-Hartman <gregkh@suse.de>
This is a driver for the ET1310 network device.
Based on the driver found at https://sourceforge.net/projects/et131x/
Cleaned up immensely by Olaf Hartman <o.hartmann@telovital.com> and Christoph
Hellwig <hch@infradead.org>
Note, the powermanagement options were removed from the vendor provided
driver as they did not build properly at the time.
TODO:
- kernel coding style cleanups
- forward port for latest network driver changes
- kill useless typecasts (e.g. in et1310_phy.c)
- alloc_etherdev is initializing memory with zero?!?
- add_timer call in et131x_netdev.c is correct?
- Add power saving functionality (suspend, sleep, resume)
- Implement a few more kernel Parameter (set mac )

+This is a driver for the ET1310 network device.
+
+Based on the driver found at https://sourceforge.net/projects/et131x/
+
+Cleaned up immensely by Olaf Hartman <o.hartmann@telovital.com> and Christoph
+Hellwig <hch@infradead.org>
+
+Note, the powermanagement options were removed from the vendor provided
+driver as they did not build properly at the time.
+
+TODO:
+ - kernel coding style cleanups
+ - forward port for latest network driver changes
+ - kill useless typecasts (e.g. in et1310_phy.c)
+ - alloc_etherdev is initializing memory with zero?!?
+ - add_timer call in et131x_netdev.c is correct?
+ - Add power saving functionality (suspend, sleep, resume)
+ - Implement a few more kernel Parameter (set mac )
+
+Please send patches to:
+ Greg Kroah-Hartman <gregkh@suse.de>
+
+And Cc: Olaf Hartmann <o.hartmann@telovital.com> as he has this device and can
+test any changes.

+ *
+ * Single Byte Writes
+ *
+ * For an EEPROM, an I2C single byte write is defined as a START
+ * condition followed by the device address, EEPROM address, one byte
+ * of data and a STOP condition. The STOP condition will trigger the
+ * EEPROM's internally timed write cycle to the nonvolatile memory.
+ * All inputs are disabled during this write cycle and the EEPROM will
+ * not respond to any access until the internal write is complete.
+ * The steps to execute a single byte write are as follows:
+ *
+ * 1. Check LBCIF Status Register for bits 6 & 3:2 all equal to 0 and
+ * bits 7,1:0 both equal to 1, at least once after reset.
+ * Subsequent operations need only to check that bits 1:0 are
+ * equal to 1 prior to starting a single byte write.
+ *
+ * 2. Write to the LBCIF Control Register: bit 7=1, bit 6=1, bit 3=0,
+ * and bits 1:0 both =0. Bit 5 should be set according to the
+ * type of EEPROM being accessed (1=two byte addressing, 0=one
+ * byte addressing).
+ *
+ * 3. Write the address to the LBCIF Address Register.
+ *
+ * 4. Write the data to the LBCIF Data Register (the I2C write will
+ * begin).
+ *
+ * 5. Monitor bit 1:0 of the LBCIF Status Register. When bits 1:0 are
+ * both equal to 1, the I2C write has completed and the internal
+ * write cycle of the EEPROM is about to start. (bits 1:0 = 01 is
+ * a legal state while waiting from both equal to 1, but bits
+ * 1:0 = 10 is invalid and implies that something is broken).
+ *
+ * 6. Check bit 3 of the LBCIF Status Register. If equal to 1, an
+ * error has occurred.
+ *
+ * 7. Check bit 2 of the LBCIF Status Register. If equal to 1 an ACK
+ * error has occurred on the address phase of the write. This
+ * could be due to an actual hardware failure or the EEPROM may
+ * still be in its internal write cycle from a previous write.
+ * This write operation was ignored and must be repeated later.
+ *
+ * 8. Set bit 6 of the LBCIF Control Register = 0. If another write is
+ * required, go to step 1.

From: Greg Kroah-Hartman <gregkh@suse.de>
Todo:
- checkpatch.pl cleanups
- sparse cleanups
- lots of little modules, should be merged together
and added to the build.
- testing?
- handle churn in v4l layer.

+ *
+ * When a new go7007 device is connected, we can look up in a board info

+ * itself here, and then we can call the registered detect_client function
+ * to force-load a new client at the address listed in the board info table.
+ *
+ * Really the I2C subsystem should have a way to force-load I2C client
+ * drivers when we have a priori knowledge of what's on the bus, especially
+ * since the existing I2C auto-probe mechanism is so hokey, but we'll use

+ default N
+ ---help---
+ This enables pushing USB packets over IP to allow remote
+ machines access to USB devices directly. For more details,
+ and links to the userspace utility programs to let this work
+ properly, see http://usbip.naist.jp/
+
+ To compile this driver as a module, choose M here: the
+ module will be called usbip_common_mod.
+
+ If unsure, say N.

This is driver for w35und usb wifi -- also in kohjinsha
subnotebook. It should work well enough to associate and ping, but it
obviously needs to be rewritten two more times...
OTOH worst horrors (like embedded wifi stack) should have been fixed
already...

+/* Implementation Notes
+ David Rowe
+ April 2007
+
+ This code started life as Steve's NLMS algorithm with a tap
+ rotation algorithm to handle divergence during double talk. I
+ added a Geigel Double Talk Detector (DTD) [2] and performed some
+ G168 tests. However I had trouble meeting the G168 requirements,
+ especially for double talk - there were always cases where my DTD
+ failed, for example where near end speech was under the 6dB
+ threshold required for declaring double talk.
+
+ So I tried a two path algorithm [1], which has so far given better
+ results. The original tap rotation/Geigel algorithm is available
+ in SVN http://svn.rowetel.com/software/oslec/tags/before_16bit.
+ It's probably possible to make it work if some one wants to put some
+ serious work into it.
+
+ At present no special treatment is provided for tones, which
+ generally cause NLMS algorithms to diverge. Initial runs of a
+ subset of the G168 tests for tones (e.g ./echo_test 6) show the
+ current algorithm is passing OK, which is kind of surprising. The
+ full set of tests needs to be performed to confirm this result.
+
+ One other interesting change is that I have managed to get the NLMS
+ code to work with 16 bit coefficients, rather than the original 32
+ bit coefficents. This reduces the MIPs and storage required.
+ I evaulated the 16 bit port using g168_tests.sh and listening tests
+ on 4 real-world samples.
+
+ I also attempted the implementation of a block based NLMS update
+ [2] but although this passes g168_tests.sh it didn't converge well
+ on the real-world samples. I have no idea why, perhaps a scaling
+ problem. The block based code is also available in SVN
+ http://svn.rowetel.com/software/oslec/tags/before_16bit. If this
+ code can be debugged, it will lead to further reduction in MIPS, as
+ the block update code maps nicely onto DSP instruction sets (it's a
+ dot product) compared to the current sample-by-sample update.
+
+ Steve also has some nice notes on echo cancellers in echo.h

+/*! \page echo_can_page Line echo cancellation for voice
+
+\section echo_can_page_sec_1 What does it do?
+This module aims to provide G.168-2002 compliant echo cancellation, to remove
+electrical echoes (e.g. from 2-4 wire hybrids) from voice calls.
+
+\section echo_can_page_sec_2 How does it work?
+The heart of the echo cancellor is FIR filter. This is adapted to match the
+echo impulse response of the telephone line. It must be long enough to
+adequately cover the duration of that impulse response. The signal transmitted
+to the telephone line is passed through the FIR filter. Once the FIR is
+properly adapted, the resulting output is an estimate of the echo signal
+received from the line. This is subtracted from the received signal. The result
+is an estimate of the signal which originated at the far end of the line, free
+from echos of our own transmitted signal.
+
+The least mean squares (LMS) algorithm is attributed to Widrow and Hoff, and
+was introduced in 1960. It is the commonest form of filter adaption used in
+things like modem line equalisers and line echo cancellers. There it works very
+well. However, it only works well for signals of constant amplitude. It works
+very poorly for things like speech echo cancellation, where the signal level
+varies widely. This is quite easy to fix. If the signal level is normalised -
+similar to applying AGC - LMS can work as well for a signal of varying
+amplitude as it does for a modem signal. This normalised least mean squares
+(NLMS) algorithm is the commonest one used for speech echo cancellation. Many
+other algorithms exist - e.g. RLS (essentially the same as Kalman filtering),
+FAP, etc. Some perform significantly better than NLMS. However, factors such
+as computational complexity and patents favour the use of NLMS.
+
+A simple refinement to NLMS can improve its performance with speech. NLMS tends
+to adapt best to the strongest parts of a signal. If the signal is white noise,
+the NLMS algorithm works very well. However, speech has more low frequency than
+high frequency content. Pre-whitening (i.e. filtering the signal to flatten its
+spectrum) the echo signal improves the adapt rate for speech, and ensures the
+final residual signal is not heavily biased towards high frequencies. A very
+low complexity filter is adequate for this, so pre-whitening adds little to the
+compute requirements of the echo canceller.
+
+An FIR filter adapted using pre-whitened NLMS performs well, provided certain
+conditions are met:
+
+ - The transmitted signal has poor self-correlation.
+ - There is no signal being generated within the environment being
+ cancelled.
+
+The difficulty is that neither of these can be guaranteed.
+
+If the adaption is performed while transmitting noise (or something fairly
+noise like, such as voice) the adaption works very well. If the adaption is
+performed while transmitting something highly correlative (typically narrow
+band energy such as signalling tones or DTMF), the adaption can go seriously
+wrong. The reason is there is only one solution for the adaption on a near
+random signal - the impulse response of the line. For a repetitive signal,
+there are any number of solutions which converge the adaption, and nothing
+guides the adaption to choose the generalised one. Allowing an untrained
+canceller to converge on this kind of narrowband energy probably a good thing,
+since at least it cancels the tones. Allowing a well converged canceller to
+continue converging on such energy is just a way to ruin its generalised
+adaption. A narrowband detector is needed, so adapation can be suspended at
+appropriate times.
+
+The adaption process is based on trying to eliminate the received signal. When
+there is any signal from within the environment being cancelled it may upset
+the adaption process. Similarly, if the signal we are transmitting is small,
+noise may dominate and disturb the adaption process. If we can ensure that the
+adaption is only performed when we are transmitting a significant signal level,
+and the environment is not, things will be OK. Clearly, it is easy to tell when
+we are sending a significant signal. Telling, if the environment is generating
+a significant signal, and doing it with sufficient speed that the adaption will
+not have diverged too much more we stop it, is a little harder.
+
+The key problem in detecting when the environment is sourcing significant
+energy is that we must do this very quickly. Given a reasonably long sample of
+the received signal, there are a number of strategies which may be used to
+assess whether that signal contains a strong far end component. However, by the
+time that assessment is complete the far end signal will have already caused
+major mis-convergence in the adaption process. An assessment algorithm is
+needed which produces a fairly accurate result from a very short burst of far
+end energy.
+
+\section echo_can_page_sec_3 How do I use it?
+The echo cancellor processes both the transmit and receive streams sample by
+sample. The processing function is not declared inline. Unfortunately,
+cancellation requires many operations per sample, so the call overhead is only
+a minor burden.

+ Blackfin NOTES & IDEAS:

+ A simple dot product function is used to implement the filter. This performs

+ history to avoid 0 length hardware loop issues. This is wasteful of

+
+ Ideas for improvement:
+
+ 1/ Rewrite filter for dual MAC inner loop. The issue here is handling
+ history sample offsets that are 16 bit aligned - the dual MAC needs
+ 32 bit aligmnent. There are some good examples in libbfdsp.
+
+ 2/ Use the hardware circular buffer facility tohalve memory usage.
+
+ 3/ Consider using internal memory.
+
+ Using less memory might also improve speed as cache misses will be
+ reduced. A drop in MIPs and memory approaching 50% should be
+ possible.
+
+ The foreground and background filters currenlty use a total of
+ about 10 MIPs/ch as measured with speedtest.c on a 256 TAP echo
+ can.

Probably, this code still needs to be cleaned up, hence the placement in
the staging tree :)
Patches gladly accepted to fix stuff like this, and anything else people
want to help out with, are always greatly appreciated.

While there are a number of small issues in this code, I personally
would like to first and foremost get a usable interface so I could get a
working echo canceller module into dahdi:
http://svn.digium.com/svn/dahdi/linux/trunk/
http://svn.digium.com/svn/dahdi/linux/trunk/drivers/dahdi/
(Don't preach me that it should be included in mainline. Or if you do,
do it in a different thread, please)
1. echo.h (The interface) needlessly includes the definition of
definition of echo_can_state_t. Anywhere in the interface it is used as
a pointer, including a _create and _destory function.
2. Furthermore, anybody that includes fir.h must also define malloc
first. See echo.c . fir.h is included for the definition of
echo_can_state_t .
3. In that specific environment (dahdi/zaptel) echo_can is not a very
unique prefix. Thus in my provisional change I added oslec_ as a prefix.
I'm not sure how much (3) counts here.
My current working tree is in not in the best place: the debian
(non-existing) package dahdi-linux . See
http://svn.debian.org/viewsvn/pkg-voip?rev=6284&view=rev
I hope that once I get a clear enough interface I can kick out the oslec
subdirectory and move the EC module upstream.

Already done, right? I don't see any _wrapper.c around.

Ok, that's great. I'm not saying that the current interface for this
driver is correct, that is why it is in the staging tree :)
It will change, don't worry.
But, what should it change into?

Simple to fix up.

That will be resolved as well.

Ok, that seems very reasonable. The whole module should probably have
that added as a prefix as well.

Care to send me patches to help resolve these issues to make it easier
for you?

Ok, different thread :)
What is needed in order for you to include this in mainline?
Can it be placed in drivers/staging for now?

I've now added 2 more patches to this tree, fixing a build error if you
did not build any staging drivers into your tree (the normal mode of
building), and added an additional wireless driver that came from the
Fedora kernel trees.
The updated diffstat and shortlog are below.
Please pull from:
master.kernel.org:/pub/scm/linux/kernel/git/gregkh/staging-2.6.git/
I'll post the 2 additional patches to linux-kernel for those who wish to
see them.

This is needed as CONFIG_STAGING is set to y, yet there is no code in
drivers/staging/ to build, so the build-in.o doesn't get created
properly. Create a "dummy" module in drivers/staging called staging.c
to work around this bug.

From: Pavel Roskin <proski@gnu.org>
Add the at76_usb wireless driver to the staging tree while the
other kernel driver (out of tree) gets rewritten to use the internal
wireless stack.
This patch comes directly from the Fedora kernel tree, with only the
directory placement of the files changed.

Heh, that's fine with me, but as you did write this code, I do want to
give you the proper credit. I'll maintain it while it is in the staging
tree.
You might want to poke John, as his version of this patch adds your name
to the MAINTAINERS file in the Fedora kernels, something I don't think
you want to have done :)
thanks,

OK, I don't care as long as I don't get any bug reports or support
requests.

erm. Exactly what is the userspace interface which this driver is

Greg - I finally got around to merging this tree, and it got some
conflicts with the changes/cleanups to taint handling (and due to the
MAINTAINERS file cleanups/alphasort). They conflicts weren't all that
nasty, and I think they're all resolved correctly, but it might be worth
testing the TAINT_CRAP flag in particular. I tested the build in the
normal config, but didn't actually bother to test any tainted drivers.
