Adrian Chadd's Ramblings

Way back in 2011 when I was working on FreeBSD's Atheros 802.11n support I needed to go and teach some rate control code about 802.11n M...

I've been chipping away at bringing up 802.11ac on FreeBSD. I've been meaning to write this post for a while, but you know, life got...

Now that I'm trying to use more userland services, there are some obvious shortcomings which need addressing. The first is a lack of r...

FreeBSD has run on these MIPS routers for quite some time, but it was limited to what ships in base. There's not been any cross-built pa...

So, it turns out that TDMA didn't work on the AR9380. I started digging into it a bit more with AR9380's in 5GHz mode and found that...

When I started with this Atheros MIPS 11n stuff a few years ago, my first test board was a Routerstation Pro with a pair of AR9160 NICs. I c...

Hi! The progress of the AR9170 FreeBSD-ification can be found here: https://github.com/erikarn/otus Yes, I did actually keep the histo...

I told myself a long, long time ago that I really don't want to be working on USB wireless. It's not that I dislike USB or wireless;...

I've been running FreeBSD at home as my primary internet/wifi access for a few years now. It's cheap, it's easy to do, and I...

I sat down a few weeks ago to make the AR8327 ethernet switch work and in doing so I wanted to add per-port and 802.1q VLAN support. It turn...

(Wow, I have a lot of posts to write to catch up on things.) I've just brought up FreeBSD's TDMA support on the AR9380 chipset. Sp...

I know that there's some collective paranoia here in the United States and in the security community in general about government and cor...

I've started adding some basic powersave support to the FreeBSD Atheros ath(4) driver. The NICs support putting parts of the device to s...

It's been a while since I posted. I'll post about why that is at some point but for now I figure it's time I wrote up the latest...

I committed a bunch of code a while ago to FreeBSD-HEAD to at least start booting on the AR934x SoCs. The AR934x SoC is a MIPS74k core - a d...

Now that the port is working, I've started doing some traffic with the carambola 2 board on FreeBSD. So far, so good: # athstats 5...

Well, "doing it right" is subjective. Sure. I'll grant you that. I brought up the AR9330/AR9331 SoC support a couple of mont...

I decided to bite the bullet and start hacking on bluetooth coexistence on these Atheros NICs. It's a bit of a rabbit hole. I'll w...

After 18 months at Qualcomm Atheros, I decided I needed a bit of a change. This is what I sent out to the open source community: Hi a...

I've been looking at implementing A-MSDU support in net80211. This has crept up for a few reasons: It means you can do basic MSDU ag...
