Hi all,
Here's a summary of the state of the drivers/staging/ tree, basically
what will be coming in the 2.6.32 merge, and what the status of the
different drivers are so far.
First off, drivers/staging/ is NOT a dumping ground for dead code. If
no one steps up to maintain and work to get the code merged into the
main portion of the kernel, the drivers will be removed.
As proof of that, the EPL (Ethernet Power Link) driver will be removed
in the .32 kernel, as no one is working on it, the upstream developers
never respond to my emails, and no one seems to care about it.
The pata_rdc driver is also going to be removed, as there is a "better"
one being merged through the libata tree for this hardware.
So, taking the drivers in chunks, here's some that have had active
development on for the .32 release:
- rt* wireless drivers. Bart has done amazing work merging all
of these together into something much better than they
originally were. And even better, they still work! Great
job Bart!
- rtl* wireless drivers. Again, Bart has been doing great work
here.
- wlan-ng driver: a bit of work here, but this seems to be
dropping off, with the loss of a test platform for the driver.
Hopefully someone has a device around and can help out here.
- comedi drivers had only a bit of work done, lots more is
needed here, let's not loose the fact that this is getting
closer to a mergable shape.
- Android drivers have had a bit of work done, but upstream
seems to not care at all about what is going on here, as they
are working to forward port their code to the 2.6.29! kernel.
{sigh}. If this keeps up, the drivers will be dropped in the
2.6.32 kernel release.
Note, Pavel has been adding some of the Dream hardware
drivers, which are separate from the core Android drivers. I
have no objection to those, but they should work to get merged
to their "correct" places in the tree in another release or
so.
- w35und driver. It's slowly being worked on.
- echo driver. This one is now in good enough shape to merge
into the main kernel tree. I'll send out review patches soon
for this.
- eth131x driver. Alan Cox is working on fixing up the issues in
this driver. Hopefully it will get into mergable shape soon.
New drivers that will show up in the .32 kernel release:
- vt66* wireless drivers. These VIA drivers are being actively
worked on to get into a much better shape. Nice job.
- new rt3090, and rtl8192e wireless drivers have been added and
worked on cleaning up issues involved in them.
- Microsoft Hyper-V drivers. Over 200 patches make up the
massive cleanup effort needed to just get this code into a
semi-sane kernel coding style (someone owes me a bit bottle of
rum for that work!) Unfortunately the Microsoft developers
seem to have disappeared, and no one is answering my emails.
If they do not show back up to claim this driver soon, it will
be removed in the 2.6.33 release. So sad...
- quatech_usb2 driver. I don't know if it quite works, but
someone is developing it, so I'm not complaining :)
- VME bus drivers. Yeah! They are progressing nicely.
- SEP and RAR drivers. Alan Cox has been working on cleaning
these up a lot.
- IIO (Industrial I/O), these are new drivers that are being
actively worked on.
- pohmelfs and dst. It seems that DST is dead, so I think I
will remove it in .33. pohmelfs is under active development
outside of the tree, and hopefully patches start moving in
here to help out with keeping it up to date.
- cowloop. Yes, another COW driver! :) Seriously, this does
things that DM can't do, so it might be useful. The upstream
developer is interested in getting this merged properly, and
is working on cleaning it up.
Drivers not being actively worked on:
- otus. This is sitting here until a "real" wireless driver
will be merged through the wireless tree. Hopefully that
happens soon.
- agnx wireless driver. No one seems to care about it. If no
one steps up soon, it will be removed in .33.
- altpciechdma. Upstream developers seem to have disappeared.
Again, if no one steps up, it will be removed in .33
- asus_oled. This only needs minor cleanups to get merged
properly into the main tree. If someone wants an easy
project, this would be it.
- at76_usb wireless driver. Again, no one working on it, it
will be dropped in .33.
- b3dfg. I really do not think anyone cares about this. again,
will be dropped if this is true in .33.
- cpc-usb. After the initial flurry of development, everyone
seems to have run away. Was it the fact that I hadn't
showered in a few days? Again, will be removed if no one
comes back. And I am wearing deodorant now...
- frontier. A nice driver, again, should not be hard to get
merged into the main tree, if someone wants an easy project...
- go7007. Ugh. Unless someone steps up now to take this over,
it's going to be removed in .33. There is no hardware made
with this anymore, and no specs around that I know of, and the
code isn't the nicest in the world.
- heci. A wonderful example of a company throwing code over the
wall, watching it get rejected, and then running away as fast
as possible, all the while yelling over their shoulder, "it's
required on all new systems, you will love it!" We don't, it
sucks, either fix it up, or I am removing it.
- line6. Another nice driver that should be simple to get
merged. Please, if you are looking for something to do, this
is it.
- me4000 and meilhaus. They work on the same hardware, and they
duplicate the existing COMEDI drivers. Someone thinks that
custom userspace interfaces are fun and required. Turns out
that being special and unique is not what to do here, use the
COMEDI drivers instead. These will be removed. Heck, I'll go
remove them for .32, there is no reason these should still be
around, except to watch the RT guys squirm as they try to
figure out the byzantine locking and build logic here (which
certainly does count for something, cheap entertainment is
always good.)
- mimio. Another driver that should be simple to get merged.
Someone just step up to do this please, there are users of
this hardware out there.
- p9auth. While it seemed like a good idea, I don't think that
anyone actually uses this. It will be removed in .33 unless
someone comes forward.
- panel. Another one that should be simple to merge. Anyone?
- phison. What? I thought I asked for this to be merged a
while ago, sorry about that, no reason it should still be in
staging anymore, it's just so small it slipped through the
cracks...
- poch. A long-suffering company is enduring the slowest
developers in the world here. Hopefully the code will be
replaced with a UIO driver, but testing the userspace side
seems to be difficult and slow. I have to give Redrapids
major credit for being patient here, they are being amazing.
- rspiusb. A weird, very expensive camera, from a company that
does not want to release the specs, and wants custom userspace
interfaces. The code hasn't built since the 2.6.20 days.
I'll go delete it now from .32, it doesn't deserve to live as
no one cares about it, least of all, the original authors of
the code :(
- slicoss and sxg. These are being developed by a consulting
company for the main producer of the chips. Yet they seem to
have disappeared half-way through the job. Odd. Hopefully
they come back soon.
- stlc45xx. Another wireless driver that no one seems to care
about. So sad. I guess no one will miss it when it goes away
in .33.
- udlfb. Video over USB, it doesn't get anymore whacked than
that. This is still being developed but the developer doesn't
like to do incremental updates for some odd reason. Hopefully
he pops up again with an update. But for now, it is quite
workable for a number of developers.
- usbip. USB over IP. I guess if you ran video over IP to your
USB device, that would be more whacked than just video over
USB. This did get one big update during the .32 development
cycle, hopefully the developer can come back again when they
get some free time to continue working on it. Rumor has it
that some major distros are starting to rely on this code, so
it would be nice to get their help to get it working better...
That should cover all of the 600+ patches in the staging tree for the
.32 kernel merge, and the existing drivers/staging/ tree. If I missed
anything, please let me know.
Any questions?
thanks for making it this far,

Work on the rt2x00 project has also progressed to a point where the
drivers are getting much closer to being useful, so eventually all this
work will have been in vain.

And do they come with their own wireless stack too?

ar9170 has been in for a while now, it's just not quite at feature
parity yet -- however that also means otus will get no work whatsoever
from any of the wireless folks. Draw your own conclusions. Personally, I
would drop it and let the users figure out whether they can live with
ar9170 or need to support work on it.

Never really worked and the reverse engineered (!) hardware specs are
incomplete, with the main developer having given up. I think it's fair
to say that this is a dead end. I suspect the hardware isn't even
manufactured any more, at least I haven't recently seen it.

There's at76c...something...-usb now, with a situation similar to the
ar9170/otus one.

p54spi has gotten probably 95% of the functionality of this, so it's
only really useful for looking at the calibration data loading on the
N800/N810 platform...

at76c50x-usb, the mac80211 port of at76_usb, has been merged mainline in
2.6.30, it works well on two at76c503a devices for me.
Performance and features are comparable (there were WPA patches[1] around,
CCMP for at76c505 devices only, but due to stability issues with the newer
firmware, they weren't merged in staging or at76c50x-usb); both drivers
sport an identical device coverage. The 802.11b chipsets themselves are
no longer in production, but were rather common (also in handhelds) around
6-9 years ago. In their current state, at76_usb and at76c50x-usb are
restricted to WEP64/ 128 or unencrypted networks and work equally well
(at76c50x-usb without the strange quirks that happen with at76_usb).

The end goal of this work has always been having native rt2x00 support
for all those chipsets (as have been explained multiple times). If this
means that one day we will delete all Ralink drivers in staging in favor
of proper wireless drivers -- fine with me.
In the meantime (before clean and proper support becomes useful) Linux
users are provided with the possibility to use their hardware before it
becomes obsolete.

Please don't put in the vendor vt6656 driver, it will conflict with a
proper mac80211 vt6656 driver a group mentored by me will submit late in
the 2.6.32 cycle.

It's already in the linux-next tree, and is almost merged with the
vt6655 driver from what I can see. When your driver goes in I will be
glad to disable the device ids that it covers, just let me know.

So should I drop at76_usb from the tree right now? It seems to cover
the same exact device ids, sorry for not noticing it yet.

Yes, please remove at76_usb from staging. It's not needed anymore now
that at76c50x-usb is in mainline. I know that some people are still
using at76_usb, but they need to convert sooner or later. And better to
force them to do it sooner.

vt665_6_ has just one usb device id. And please make sure to rename the
crap driver to something else than vt6656.ko so that it does not get in
way for the proper driver.

Ok, does vt6656_crap.ko sound good to you? :)

Ok, it's now gone from my tree, and will be deleted in 2.6.32.

Greg, as Johannes noted otus has lacked focus as Johannes whipped out
a port for it in a few weeks and then Christian gave it some final
love taps for inclusion, we just still use otus as just a source of
documentation for any yet missing feature, but for that I guess I can
just refer people to my git tree. Chris would know better where we're
at as far as feature-parity is concerned though so I'll leave it up to
him to judge whether or not having otus gets some users anything
ar9170 doesn't yet have.

Ok, as I've said before, just let me know when you want the otus driver
removed from the tree and I'll be glad to do so.

I have a USB-Stick with prism2-chipset (Netgear MA111v1) that I succesfully
used with wlan-ng in the past. If it is of any help for further
development, I would donate it. Is somebody interested?

can we suffix all of the staging drivers with _crap actually? At least
for the wireless ones.

Heh, no, the "crap" name is internal only, we don't expose that to
users.

I just got an email from a guy who proposed to work on it and who
showed me he's currently running tests and fixing a bug when removing
the module.
Hopefully he'll make enough progress to get the driver merged.
This proves that the principle of the staging tree seems to work,
and that your call was useful ;-)

Well, some of those drivers should be moderately easy (touchscreen),
but some (camera) will take longer than that. For example camera --
contains _lots_ of code, and uses obsolete v4l api.
Plus, I really need to get recent kernel to boot and then get arch/arm
pieces merged....
So next release is a bit optimistics, but I'm (slowly) working on it.

I've got a tree with a lot of the arch/arm/msm pieces isolated, doesn't
boot yet .. I had to drop certain parts like the key pad support since
it had a big generic change attached to it .. It's all part of a git
tree which I can expose if you want to look at it.

The usage of the obsolete V4L API is a problem since we aren't accepting any
drivers with the old API for a long time, doing large efforts to convert the
few remaining ones to V4L2 API.
This probably means also that they are not using the current V4L framework. Are
they already somewhere at the staging tree?

Mauro

I think nobody will cry if you remove this one. This is an old hardware, and not
manufactured anymore. The chipset of the compression hardware is
obsolete and orphaned, as the audio/video unit were sold to another company.

Is this a video streaming driver (like other V4L2 drivers) or a video adapter
driver?

I agree. I do have a device around here, but it was only for testing,
the company who produced it said they could not release the specs due to
ownership issues.

Video adapter driver, it's a frame buffer driver, sorry for any
confusion.

Big question is... 'does it boot?' :-). The rest should be easy.

It will appear in drivers/staging/dream/camera in 2.6.32 or so. It
should be in -next by now.

Yes, minimal, but booting version would be very welcome. I tried to
produce exactly that few times, but did not succeed (yet).

Last night I discovered maybe a better tree to use ..
https://www.codeaurora.org/gitweb/quic/kernel/?p=bryanh/linux-2.6.git;a=summary
It's based off a newer kernel 2.6.31-rc6 . I have a feeling it's minus a
lot of the google stuff.

Did you get it to boot? ... ... It does not seem to contain any HTC
Dream stuff; why do you think it is interesting?

That would be somewhat surprising, since the qct/quicinc folks support
the full android stack on top of their kernels (though we're not
entirely converged at this point).
Not sure if their tree has full support for devices like
dream/sapphire/etc -- I believe they primarily verify on their SURF
platform. Added Bryan to the CC so he can comment.

Brian, the tree you reference is not for Android. It's just a minimal tree to boot our internal SURF platform on .31. It may have some android bits in it but they are not used. We only validated console and the sd bus driver. Our latest released Android tree is https://www.codeaurora.org/gitweb/quic/la/?p=kernel/msm.git;a=shortlog;h=refs/heads/android-msm-2.6.29b. It's based on your android-msm-2.6.29 branch from back in May and has whatever dream/sapphire support you had at that time.

yeah - Greg's call definitely was useful!
Although I'm still not sure if there is a point to getting the driver merged
or not -- see discussion: "staging panel driver"
http://driverdev.linuxdriverproject.org/pipermail/devel/2009-September/001610.html
More opinions/suggestions are welcomed - especially from people who are more
into lcdproc than I am.
However I'm currently working on it anyways - I already eliminated the bug:
while removing the module misc_deregister gets called twice (keypad and led -
both twice) - once in the panel_detach function and once in the
panel_cleanup_module function.
And of course the second call fails :)
I will provide a (very simple :) patch to these issues tomorrow.
Thanks,
Peter
