Hi all,
I have a box here with a Realtek 8821 wireless PCI device. We don't
seem to have a driver upstream for it yet, but there's a huge tarball
from Realtek on their site.
Has anyone started picking the needed pieces out of the tarball to get
this merged "properly", or does this need to be done yet?
Hm, I wonder if I should just dump the tarball into staging for now, to
get my box working, any objections to me doing that?
I have had contact with the Realtek developers regarding a Linux driver for the
RTL8821AE device with PCI ID 10ec:8821. On Dec 10, 2013, they indicated that
there were still 802.11ac problems, and they were not yet ready to release it to
me. I will write them again and check if the driver is now ready, and they just
forgot to send it to me. Once they are ready, they will also be sending me
sample devices.
What is the URL for the driver that you found? I did a quick search on their
site and did not find it.
It came with a device I got at a conference, along with 1,000 other
people, so it's being used in the "wild" now, running Linux. I'll send
you the patch off-list as it's not small.
To answer your question, I certainly would have no objections to your dumping
the driver into staging. I can fix it up there as easily as in my own private
stores. You will, of course, get a lot more intermediate patches, but I think
you have already anticipated that. The PCI group usually send me mac80211-based
drivers, thus the residence in staging may be short, but that is desirable.
Ok, I spent an hour or so trying to see if I could just use the existing
rtlwifi module with this driver, but it seems that they are using a 2
year-old version of it, so I'll have to bundle it directly into the
driver for now, along with an "odd" bluetooth sharing module. I'll work
on making the needed changes to the driver to get it to work with
rtlwifi first, and then clean up the rest over the next few months. I
have the hardware here to test with, so that should make it easier than
the normal staging driver work I do.
But for now, staging seems like a good idea, especially as one "distro"
is already shipping it in this form (SteamOS).
Too bad I couldn't get one of those devices.
The "odd" bluetooth sharing module is part of a new driver that I am about to
push into drivers/net/wireless to be part of 3.15. This one drives the RTL8723BE
device, which is somewhat different from the existing RTL8723AE. Both of the
8723 device are both wifi and BT, and it also seems that the 8821AE is also a
dual device.
I will merge the 8821 code with my current working version of rtlwifi and
becoexist, and send you patches for testing. I agree that staging is a good
place for now.
Thanks for the heads-up on this matter.
Larry
