@emilazy:matrix.orgemilyhttps://microchip-ung.github.io/bsp-doc/bsp/2025.03/network_overview.html these switch SoCs apparently have meaningful amounts of upstream support05:14:29
@emilazy:matrix.orgemilythough it seems like they're automotive stuff that I have no idea whether you can just find consumer products with05:14:39
@emilazy:matrix.orgemilyit seems like at least one family has "normal" ARM verified boot05:15:02
@abyxcos:beeper.com@abyxcos:beeper.com left the room.14:29:45
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zone emily: it looks to me like the only openwrt supported switch worth getting is XikeStor XikeStor 15:45:08
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zone * emily: it looks to me like the only openwrt supported switch worth getting is XikeStor SKS8300-8X 15:45:12
@emilazy:matrix.orgemilythe TP-Link one seems fine too15:45:30
@emilazy:matrix.orgemilythere's also a 12 SFP+ one from XikeStor15:45:44
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneAh yeah but I can't find a way to buy that one15:45:52
@emilazy:matrix.orgemilyand Ubiquiti USW-Aggregation seems like it might be supported15:45:54
@emilazy:matrix.orgemilythere is plenty more hardware with DSA and switchdev modules in the kernel tree though15:46:03
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneI have to use aliexpress just to get the XikeStor one in any case15:46:12
@emilazy:matrix.orgemilyand some of the switches using them can use vanilla kernels, cf. https://blog.benjojo.co.uk/post/sn2010-linux-hacking-switchdev15:46:21
@emilazy:matrix.orgemilyso there may be better options that avoid MIPS15:46:37
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneMellanox SN2010 is 7K15:47:36
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneRedacted or Malformed Event15:47:41
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneah crap for got15:47:46
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zone* ah crap forgor15:47:49
@emilazy:matrix.orgemilymuch less second hand, but obviously I wasn't recommending actually buying a 100G switch15:55:12
@emilazy:matrix.orgemilyI'm saying that there are things that can trivially run vanilla Linux with the upstream DSA/switchdev drivers and involve no MIPS15:55:35
@emilazy:matrix.orgemilyso there may be an option that does not require the OpenWrt Realtek stuff15:55:47
@emilazy:matrix.orgemilythough it's being upstreamed anyway15:55:50
@emilazy:matrix.orgemilyit's just the MIPS and tiny flash that make it annoying, because otherwise you could just run NixOS15:55:59
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneTL-ST1008F is the best, but costs the most simply because ti is rare16:05:56
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zone* TL-ST1008F is the best, but costs the most simply because it is rare16:06:00
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zone It's incredible that there are only two on the market don't you think emily 16:21:22
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zonedo you think someone bought all the stock, and is now selling it back to us?16:21:33
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zonethis stuff used to be on amazon, and now it is not16:21:43
@matthewcroughan:defenestrate.itmatthewcroughan - nix.zoneTP-LINK TL-ST1008F and the XikeStor stuff, but not much else with this performance 16:22:14
