#nixwrt

Linux version 5.4.64 (nixbld@nixwrt.builder) (gcc version 9.3.0 (GCC)) <a href="https://terse.telent.net/tags/1" class="mention hashtag" rel="tag">#<span>1</span></a> Tue Sep 15 13:33:49 UTC 2020

Pausing here for a brief "woohoo!"

It doesn't mount the root fs yet, maybe (it suddenly occurs to me literally as I write this toot) because I forgot to build the phram target. And then the next big task is to build wireless modules from linux-backports. And maybe, y'know, actually commit some stuff to git?

TFW when you set out to benchmark something you've previously observed is inexplicably slow, and ... it's no slower than the other thing you're comparing it against

#nixwrt wireless performance on this gl-mt300a (MediaTek MT7620A SoC) is about ~ 14Mb/s according to iperf3, which is probably slower than I should expect but is on par with the 2.4GHz network on the gl-ar750 downstairs running the vendor's OpenWRT

  • The LZMA decompression code in u-boot doesn't understand the LZMA compression performed by xz, so to get #nixwrt to generate images that work I have to build the "legacy" lzma (from 2008). Upgrading nixpkgs caused its buiild to fail with "RPATH ... contains a forbidden reference to /build"

  • so I worked around that by configureFlags = [ "--enable-static" "--disable-shared"]

  • now it is building gcc again. Guess I must have changed something else fundamental ...

I'm not saying it works, because it doesn't, but my ath10k wireless at least appears now to exist in #nixwrt. This is progress and it makes me happy
