MT7630e availability in kernel by default

MT7630e availability in kernel by default

[Powerful Notageek]

Hello, 

I was wondering if anyone here would know when the drivers for this card will be added to the kernel by default. 

03:00.0 Network controller: MEDIATEK Corp. MT7630e 802.11bgn Wireless Network Adapter

Thank you.

Supplying the line from 'lspci -nn' is a lot more helpful than just lspci.

According to the Web, the wireless chip is from Ralink. There is a git repo that 
is supposed to have a driver for the device, but it is full of the standard 
rt2xxx driver files. Perhaps it will work with newer kernels, or by adding the 
PCI ID to an existing driver. In any case, we need the PCI ID.

Here's lspci -nn

03:00.0 Network controller [0280]: MEDIATEK Corp. MT7630e 802.11bgn Wireless Network Adapter [14c3:7630]

I have tried using the drivers available on RALink/Mediatek on a pretty recent kernel of Fedora20, didn't seem to work. 

Thanks

That PCI ID is not in the latest Ralink driver, which is essentially what will 
be in kernel 3.16.

Please try the following:

su -
modprobe -v rt2800pci
echo "14c3 7630" > /sys/bus/pci/drivers/rt2800pci/new_id

Does that yield a wireless lan device?

When you do the above, what ends up in the dmesg output? In particular, is the 
firmware available?

Larry

Re: MT7630e availability in kernel by default

[Powerful Notageek]

dmesg says nothing and there's probably no firmware for the device (although linux-firmware is installed) 

These are the firmwares available to me: 

[root@localhost ~]# ll /usr/lib/firmware/rt2*
-rw-r--r--. 1 root root 8192 Mar 18 00:08 /usr/lib/firmware/rt2561.bin
-rw-r--r--. 1 root root 8192 Mar 18 00:08 /usr/lib/firmware/rt2561s.bin
-rw-r--r--. 1 root root 8192 Mar 18 00:08 /usr/lib/firmware/rt2661.bin
-rw-r--r--. 1 root root 8192 Mar 18 00:08 /usr/lib/firmware/rt2860.bin
-rw-r--r--. 1 root root 8192 Mar 18 00:08 /usr/lib/firmware/rt2870.bin

Thank you.

I looked more closely at the code in https://github.com/anthonywong/mt7630. 
There are a number of places where there are branches specific to the MT7630. It 
also needs a firmware file named mt7630.bin. Unfortunately, that file is not 
found in the repo, and a quick Google search failed to find it. The 
linux-firmware git repo has a file named mt7650.bin, but I think that is 
Bluetooth firmware.

Unfortunately, there does not seem to be an easy fix, and only someone with the 
hardware could modify rt2800pci to support this device.

Re: MT7630e availability in kernel by default

[Powerful Notageek]

Thank you for taking time to investigate it with me. Essentially, the driver for it doesn't exist in any form and maybe it will be introduced at a later release after 3.16. 

Thanks again, appreciate it very much.

I bought such a device on EBay for $6.99. nce it arrives, I will try to modify 
rt2800pci to handle it when I get some time.

I'd also be willing to help you test your changes. I can follow instructions, if you'd tell me what to do. 

Thanks.

This driver is quite nice mix of rt2800pci and Mediatek/Ralink driver,
where MT7xx code was copied into rt2x00 from venodr driver. It can be
good start for adding support for mt7xx devices to rt2x00.

Indeed, it is hard to find it.

Yep, some substantial amount of work is needed to add support to new
MT7xxx chips properly to rt2x00.
