[CFT] Ralink RT2860, RT2870, RT3060, RT3090 support

[Bernhard Schmidt-6]

Hi folks,

As some of you might know there has been some work going on porting
support for new Ralink chipsets from OpenBSD. Several different
drivers where floating around but nothing seemed to be decent enough
to be committed. ray@ and I had been working on cleaning up one of
those to get it into a good enough shape, but abandoned this approach
as it resulted in more work than starting from scratch.

So, attached diff [1] is a from-scratch effort to port over support
for the new chipsets. It doesn't contain fancy stuff like 802.11n
support as of yet (this will be worked one once the legacy stuff is
in HEAD), nonetheless it showed pretty decent performance during the
basic sta/adhoc/hostap tests I've done.

I'd appreciate testing and feedback ;)

The diff requires HEAD due to the firmware being available only there,
though, if there are enough requests, I might consider looking into
getting it merged to 9. (Simply pulling sys/modules/ralfw/ and
sys/contrib/dev/ral/ from HEAD might be enough I guess.)

Hi,

First off, let me say "thankyou" to you, ray@ and all the people who
have chipped away at this little problem. I look very forward to
having rt2xxx 802.11n support, as do many users on the forums. :)

I haven't yet done a pass or two to see what the state of the
locking/concurrency handling is. Don't let that stop you from
committing it though, I'm sure we can find/fix whatever issues creep
up post-commit.

Thanks again!



Adrian

Thanks Bernhard!

I'm sure there are many people with this chipset that are going to be
very happy.
It's good that we have something homegrown as well.

I'll try to test it this weekend on my rt3090.

That interval is fishy.. can you try do disable bgscan?
ifconfig wlan0 -bgscan

Please apply attached patch (also here [1]) on top of the first one,
it fixes channel switching for >= 3070 (called the wrong function,
doh..) as well as a bgscan issue.

* patch applied without errors
* build/install - ok

kldload and after ~5 minutes:

May  5 15:01:20 laptop kernel: ral0: device timeout
May  5 15:06:12 laptop kernel: ral0: device timeout

without bgscan I didn't see such messages  ~30-40 min

Ok great, so except bgscan you haven't seen any other issue yet?

Hi,

FWIW, "device timeout" may just be watchdog related race conditions,
rather than an actual hardware device timeout.

I have the same issues in ath(4). I need to fix a whole lot of locking
constructs before I can fix 'that'.

And another update [1] on top of the other 2 patches.

* fix TX DMA, a wrong dmat has been used
* add some more PCI IDs
* disable debugging output by default
* disable bgscan until it's sorted out
* a printf is now hidden behind bootverbose

So far it looks quite good, no open issues at the moment, keep on testing! ;)

If nothing new comes up within the next few days I intend to commit
this by the end of the week or something.
