| Kamilion | CarlFK[m]: pong | 00:16 |
|---|---|---|
| CarlFK[m] | Kamilion: check your email 😋 | 00:17 |
| CarlFK[m] | Kamilion: I need 10 pci 90s, and some pci power plugs, and if I could have out in your office for a few hours soldering some stuff... | 00:19 |
| Kamilion | uhhh, I'm not following... | 00:22 |
| Kamilion | PCI 90s? | 00:23 |
| Kamilion | ... PCI power plugs? ... What the hell is a PCI power plug? | 00:23 |
| Kamilion | sorry, I had a late night last night working on some microcontroller stuff | 00:24 |
| Kamilion | I don't think we have any PCI stuff at all anymore... maybe some PCI-X network cards | 00:25 |
| Kamilion | I've got a DEC 21040 PCI NIC hanging around somewhere still, but it doesn't work with anything modern, since it requires edge triggered interrupts and we use level triggered and MSI-X interrupts now | 00:26 |
| CarlFK[m] | PCI | 00:28 |
| CarlFK[m] | PCI 90-degree risers? That let you stick a card in a 1U box | 00:29 |
| Kamilion | yeah, we don't have any PCI stuff anymore. all PCIe | 00:30 |

| Kamilion | that's PCIe power | 00:30 |
| Kamilion | or commonly referred to as GPU power | 00:30 |
| CarlFK[m] | Pcie, right | 00:32 |
| Kamilion | distracted a lot right now | 00:33 |

| Kamilion | on the horn with a friend blabbing about his rust server | 00:33 |
| CarlFK[m] | Heh. I'm helping a friend pack up his office | 00:37 |
| Kamilion | i think we have some pcie risers | 00:40 |
| CarlFK[m] | Yay. I liked the samples you gave me last time, with ribbon cable to make the turn | 00:41 |
| Kamilion | i doubt we have anything like that left | 00:42 |
| Kamilion | https://www.amazon.com/Supermicro-RSC-RR1U-E16-Riser-Card/dp/B003S71DUI | 00:42 |
| Kamilion | this is pretty much all I have for a single slot riser | 00:42 |
| CarlFK[m] | <freenode_Kam "https://www.amazon.com/Supermicr"> Shucks. I still need 10, can I stop by tomorrow or Thursday? | 00:46 |
| Kamilion | sure, you can stop by; I dunno if I have anything useful, but sure, you're welcome to my soldering iron | 01:15 |
| Kamilion | i'm low on thin solder though | 01:18 |
| Kamilion | only got the thick "electrical" solder left | 01:18 |

| Kamilion | sure, they should have some Delta brand 0.032" 3.3% flux 60/40 for about $2, item id 4455316 | 01:49 |
| Kamilion | crap, my BMC just crashed, gonna have to reboot and lose my scrollback | 02:43 |
| Kamilion | Hrrm, got everything squared away for today, I guess. | 03:12 |
| Kamilion | We've got lots of redundant power supplies; but a scarcity of desktop PSUs, so I'm afraid there's nothing we have with PCIE power | 03:13 |
| Kamilion | I've got at least two modular supplies, but I'm missing all the modular cables; since we've been using them as motherboard testers for a long time | 03:13 |
| Kamilion | I know we have some of the 8 lane PCIE risers; not sure if we have any sixteens | 03:14 |
| Kamilion | and the machines with the ribbon cable risers have long since been EOL and been torn down | 03:15 |
| Kamilion | they've been throwing away fans by the boxload because we simply don't have enough room to store small parts efficiently | 03:16 |
| Kamilion | yeah, I don't think I have anything that can fit that milkymist board | 03:17 |
| Kamilion | TOFE's pinout of the power pins appears to be incompatible with the supermicro risers and the capacitors on 'em. | 03:18 |
| Kamilion | at one point we had some unbranded passive risers that were straight through | 03:20 |
| Kamilion | but all the risers I have now have conjoined pins for the PCIE grounding | 03:20 |
| Kamilion | lemme pop the dvx100's crate open and give the batteries some juice. | 03:23 |

| Kamilion | that shipping option is $18ish | 03:51 |
| Kamilion | "Order total: $108.29" | 03:51 |
| * Kamilion aborts the order | 03:51 | |
| Kamilion | both of those are straight through X8 ribbon extenders "for mining" so as far as I can tell, none of the pins are tied together; thus it should work fine with TOFE. | 03:52 |

| felix_ | i'm currently working on a design in migen/litex and wonder what's the best way to instantiate multiple instances of one component and also connect the inputs and outputs (output of each component ends up in one bit of a signal that's the output of that whole module) | 18:57 |
| felix_ | or to rephrase the question: when i write something like "for i in range(channel_count): self.submodules += Foo(i)" how do i acccess the outputs from Foo? | 19:00 |
| felix_ | well, from the instances of Foo | 19:00 |
| felix_ | does passing the target signal as parameter to the constructor of Foo work? | 19:04 |
| CarlFK | mithro: ^^^ hi felix_! | 19:06 |
| felix_ | hi CarlFK | 19:06 |
| felix_ | i'm currently trying to build a design to test the axiom-photonsdi-hw board; got a really neat idea from herbert from apertus to output a different binary number (or ascii character if the values are in the right range) in uart style on each pin going to a connector, so that you can check all connections with just a logic analyzer or even a simple usb uart thing | 19:09 |
| felix_ | oh, wait, i think i have a better idea for the implementation; just using one module, but an array of signals should probably also do the trick with even less logic being generated | 19:12 |

| felix_ | is there a simple construct in fhdl that's equivalent of (others => '1') or (others => '0') in vhdl? | 20:52 |
| *** benreynwar has quit IRC | 20:53 | |
