In reply to @hexa:lossy.network
so, any takers? I'm thinking about ripping out nettools from every module that I can find next
I will if still needed by tomorrow noon ish

@emilazy:matrix.orgemilyhttps://serd.es/2025/05/08/Switch-project-pt1.html https://serd.es/2025/06/23/Switch-project-pt2.html https://serd.es/2025/07/04/Switch-project-pt3.html not Nix but "This is part 3 of my ongoing series about LATENTRED, my project to create an open source 1U managed Ethernet switch from scratch."12:52:23
@emilazy:matrix.orgemilywho's gonna get NixOS on it12:53:27
@emantor:stratum0.orgEmantorI quickly skimmed the articles and it looks like this is a purely FPGA based switch design, so my guess is that the CPU is running within the FPGA if there is need for one. The specs of the FPGA look like it may be barely able to run linux, however I would not bet on that.12:59:31
@emantor:stratum0.orgEmantorIf you want something that can run Linux it is a lot easier to look at the switches that OpenWRT recently added.13:01:03
@hexa:lossy.networkhexaor buy one of the funny whitelabel switches that (used to) run cumulus linux13:03:44
@hexa:lossy.networkhexathey come with onie, an installer environment that explicitly supports installing things to it13:04:35
@hexa:lossy.networkhexafun post wrt that https://blog.benjojo.co.uk/post/dell-switch-hacking13:04:59
@hexa:lossy.networkhexathe problem will of course be broadcom firmware/drivers in most scenarios 🤪13:05:19
@molly:matrix.flyingcircus.ioMolly Milleri was about to say, that trick only works if you have a kernel driver for the asic, right?13:05:34
@molly:matrix.flyingcircus.ioMolly Milleri have a number of whitelabel onie switches at work but they're all broadcom asics13:05:47
@hexa:lossy.networkhexathe alternative is something from mellanox, but those are sfp+/sfp28 and larger only iirc13:05:49
@hexa:lossy.networkhexayeah, the mellanox ones have mainline support13:06:03
@hexa:lossy.networkhexathe broadcom ones are fckd13:06:13
@emantor:stratum0.orgEmantorBroadcom, more like: https://github.com/mwarning/chaos-sticker-collection/blob/9f0415d815bbef4a01bf55bc3fe57bb75e4247bd/images/brokencom/brokencom.svg#L413:06:24
@hexa:lossy.networkhexaso no copper connections13:06:27
@emilazy:matrix.orgemilyyeah I hadn't actually read them when I said that 😆13:06:43
@emilazy:matrix.orgemilyI just saw "managed"13:06:47
@hexa:lossy.networkhexathough you can do dacs and copper sfps13:06:49
@molly:matrix.flyingcircus.ioMolly Millershort of yanking the cumulus kernel sources package and switchd binary debs from the nvidia mirror and hacking something together13:06:55
@hexa:lossy.networkhexa* though you can do dacs/aocs and copper sfps13:06:58
@molly:matrix.flyingcircus.ioMolly Millerwhich, well, probably isn't really worth the effort13:07:18
@emilazy:matrix.orgemilyI wish I could justify the price of the https://blog.benjojo.co.uk/post/sn2010-linux-hacking-switchdev one13:07:42
@emilazy:matrix.orgemilyI've looked at the OpenWrt switch support fairly recently but do you have a pointer to what new stuff they added?13:08:32
