Add firmware for mt7601u. version 34.
http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/commit/?id=9df5430

Thanks Hua Shao for the firmware,
and of course,
thanks Jakub Kiciński for the driver.

Oh yeah!

Yes this works because it contains a forked and bitrotting copy
of the entire Mediatek code drop including a fork of rt2x00 from
the v3.10 kernel. It's not going to last, and I can't
get it to compile properly with the most recent Fedora kernel
relase (v4.3.x-based).

Ubuntu will also run into the problem sooner or later. :(

Mediatek wifi

[Anca Emanuel]

Hi Linus Walleij, and everyone interested.

http://askubuntu.com/questions/676390/no-wi-fi-on-ubuntu-14-04-lts-asus-notebook-with-mediatek-mt7630e

Here is the bug report:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1220146

https://github.com/neurobin/MT7630E is reported to work for wifi.

Maybe it works to add usb ids to
https://github.com/torvalds/linux/tree/master/drivers/net/wireless/rt2x00
and firmware.

mt7601u landed in 'linux-next'
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/log/drivers/net/wireless/mediatek/mt7601u

the v4.2 kernel is predicted for Sunday, 2015-08-23
http://phb-crystal-ball.org

For the firmware(mt7601u.bin) as part of the essential functionality of the 
device
it would be good to land in 'linux-firmware' *even* before the actual kernel 
release v4.2

Re: MediaTek WiFi hardware support in upstream kernel

[Etna]

This is sorely needed given the miserable state of wifi drivers in the 
Linux kernel.


Kernel maintainers, can this be pushed to mainline? It's not a vendor 
driver after all, and it uses nl80211 instead of WEXT.



Regards,
Etna

I assume you mean to ask how many different drivers are there. There 
is the vendor 3.0.0.4 STA driver which only has client functionality. 
Many patched versions of this driver exist on GitHub. There is also 
an older version of vendor driver which can work as an AP. My 
mac80211-based driver is the only non-vendor version I'm aware of.

 Hi, Jakub! I happen to have 7601 dongle, so I tested you driver. There
 were some problems, see dmesg | grep mt7 output:

OK, let me start with a set of basic questions.

What device do you have (brand + model or picture on ebay please;))?
What's the device ID?
What platform are you working on?
Is this error persistent or a one-time thing?
Does the vendor driver work with your device?
Can you also show content of

Firmware clearly died somewhere between switch to channel 1 and to

to check the traces later today to confirm that I didn't break anything.

 Is it because of unsupported EEPROM version 0d?

Don't think so.  It's just for compatibility with vendor driver,
they warn too.  All new devices have EEPROM ver == 0x0d though.  I plan
to ask MediaTek about it in a week or two (Chinese New Year) and
remove the warning.

Is it because of unsupported EEPROM version 0d?

Re: MediaTek WiFi hardware support in upstream kernel

[Jakub Kiciński]

Hello everyone!

I put together a mac80211 driver for Mediatek MT7601U.  It's partially
based on Felix's mt76, but I'm not sure if it will make sense to merge
the two together.  MT7601U is a pretty old 1x1 bgn chip for USB dongles
and mt76 now only supports the latest and greatest ac APs.

I'm testing STA functionality right now and it seems to be working ok.
The code is very much a work in progress but if anyone is interested you
can get it here:

https://github.com/kuba-moo/mt7601u

Cheers,
kuba

 Hi Hackers,
 
 Just a quick heads up:
 I'm working on a new driver for MT7662E/MT7612E, written from scratch.
 It is already able to bring up the firmware, init the MAC and do basic
 TX/RX DMA communication with the firmware.
 I've decided to not integrate it with rt2x00, because I want to avoid
 dealing with the the unnecessarily convoluted abstractions and legacy
 code in there. I believe the result will be simpler and easier to
 maintain as a new driver.
 As soon as the basic structure is in place, I will put it on a public
 git tree and post a link here.

 Which chip would you suggest for starting?
The chips I'm working with are both MT7662 and MT7612. My driver already
works as a simple AP or station in 802.11n mode with some limited
aggregation support. I'm getting around 45-50 Mbit/s TCP throughput on
HT20 with iperf. I will post code soon, stay tuned!

Felix,

If your driver will work with the MT7630, I will be happy to test it when 
posted.

 Sounds interesting and as perfect possibility to learn. I would like to
 do it, but i have two concerns:
 - i never wrote an wifi driver from scratch.

FWIW, I think MediaTek already has some form of drivers.  With that
said, it might be easier to write new mac80211-based ones than to
adapt the existing ones.

 - i'm seeking for a job. It means if i will find one, this project will
 get lower priority.

No one can ask anything more.

 If nobody has problems with this two points, then i'm ok.

It sounds like we have a volunteer!  Let me know if you need any
specific help or guidance.

 During LPC Felix mentioned GPLed mediatek driver for their 11ac
 chipset(s?). It is on github:
 
 https://github.com/openwrt/mtk-wifi-gpl

What is the next step?
