 hexa | klipper is where open source 3d printing is today | 16:00:24 |
 matthewcroughan | yeah I haven't touched a 3d printer for like 2-3 years, really, so that's the only reason I mention marlin | 16:00:41 |
 emily | btw you still need a firmware blob for the switch chip | 16:05:20 |
| emily | in re foss | 16:05:23 |
| matthewcroughan | that's fine, I just want as much as possible to be FOSS rather than nothing being foss | 16:19:43 |
|  oddlama changed their display name from Malte to oddlama. | 17:42:03 |

| emily | https://microchip-ung.github.io/bsp-doc/bsp/2025.03/network_overview.html these switch SoCs apparently have meaningful amounts of upstream support | 05:14:29 |
| emily | though it seems like they're automotive stuff that I have no idea whether you can just find consumer products with | 05:14:39 |
| emily | it seems like at least one family has "normal" ARM verified boot | 05:15:02 |
|  @abyxcos:beeper.com left the room. | 14:29:45 |
| matthewcroughan | emily: it looks to me like the only openwrt supported switch worth getting is XikeStor XikeStor | 15:45:08 |
| matthewcroughan | * emily: it looks to me like the only openwrt supported switch worth getting is XikeStor SKS8300-8X | 15:45:12 |
| emily | the TP-Link one seems fine too | 15:45:30 |
| emily | there's also a 12 SFP+ one from XikeStor | 15:45:44 |
| matthewcroughan | Ah yeah but I can't find a way to buy that one | 15:45:52 |
| emily | and Ubiquiti USW-Aggregation seems like it might be supported | 15:45:54 |
| emily | there is plenty more hardware with DSA and switchdev modules in the kernel tree though | 15:46:03 |
| matthewcroughan | I have to use aliexpress just to get the XikeStor one in any case | 15:46:12 |
| emily | and some of the switches using them can use vanilla kernels, cf. https://blog.benjojo.co.uk/post/sn2010-linux-hacking-switchdev | 15:46:21 |
| emily | so there may be better options that avoid MIPS | 15:46:37 |
| matthewcroughan | Mellanox SN2010 is 7K | 15:47:36 |
| matthewcroughan | Redacted or Malformed Event | 15:47:41 |
| matthewcroughan | ah crap for got | 15:47:46 |
| matthewcroughan | * ah crap forgor | 15:47:49 |
| emily | much less second hand, but obviously I wasn't recommending actually buying a 100G switch | 15:55:12 |
| emily | I'm saying that there are things that can trivially run vanilla Linux with the upstream DSA/switchdev drivers and involve no MIPS | 15:55:35 |
| emily | so there may be an option that does not require the OpenWrt Realtek stuff | 15:55:47 |
| emily | though it's being upstreamed anyway | 15:55:50 |
