JohnSelfI have a question05:27
JohnSelfis anyone here to answer?05:27

mor1kxmor1kx/master d851189 Stefan Kristiansson: cappuccino: remove ctrl_opc_ins...05:30
mor1kxmor1kx/master c8f7201 Stefan Kristiansson: (pronto)espresso/cpu: regenerate05:30
stekernJohnSelf: how should we know when you haven't asked the question?05:31
JohnSelfI was wondering how far along you have got with the design of the kncminer units05:34
JohnSelfi.e. what stage you are at now, and what target you have for production05:36
JohnSelfin terms of the target date05:36
stekernhmm, what does kncminer have to do with openrisc?05:41
JohnSelfmy mistake05:45
JohnSelfbut perhaps you could tell if the openrisc designs are advanced enough to be mass produced?05:47
stekernor1200 is stable enough for that, yes05:56
JohnSelfi thought so, great05:57
JohnSelfI was hoping someone from orsoc would be here.05:57
stekernolofk and LoneTech works at orsoc05:58
JohnSelfWell if either of you come online, I'd love a rough estimate for kncminer units 1.006:00
JohnSelfThanks for your help stekern06:01
stekernwhat is kncminer?06:09
JohnSelfsome company that is claiming it will ship 500 orsoc-designed asic units within months06:21
JohnSelfI don't have much technical education but that seems unrealistic to me given the problems other asic developers have had.06:22
JohnSelfBut I'm interested to hear from someone who is working on it.06:22
stekernjuliusb: I have prepared this patch for (pronto)espresso:
stekernit's a follow-up on this:
stekernwhich move the lsu op code decoding into the decode module11:47
stekernfor espresso, there is no practical change, but I prepared the patch to keep the lsu code more concistent between the pipelines11:48
stekernin hindsight, I probably should have broke that cappuccino/lsu commit in two, one that adds the decoding to mor1kx_decode and one that does the changes to lsu (like the patch I've now prepared for espresso)11:49
stekernanyways, what's your opinion on the espresso patch?11:50
@juliusbstekern: i like the patch13:35
@juliusbI assume it works against the tests?13:35
@juliusbbtw hello all from the London chip hack14:24
stekernjuliusb: yup, all tests passes14:29
stekernI'm playing a bit with the adder again, I noticed that the adder in or1200 gets inferred as a lpm_add_sub when compiled with the altera tools, but I can't for my life get the one in mor1kx to do that14:32
stekernnot sure if it makes a difference, but worth a try14:32
@juliusbhmm, using macros is nice14:34
@juliusbbtw please commit that patch if you like14:34
@juliusblooks good to me14:36
stekernI will, on the run right now14:43
mor1kx[mor1kx] skristiansson pushed 1 new commit to master:
mor1kxmor1kx/master 8bba14a Stefan Kristiansson: (pronto)espresso/lsu: move length end extension decoding to decode...15:49
stekernlooks like you can do git pushes from this phone at least ;)15:50
stekernhmm, the code examples from altera has the result registered, maybe that's required for lpm_add_sub16:30
stekernwell, I think I leave that alone for now, maybe we should just put the adder as a seperate module, that way users can more easily put their own (optimised) adder in there17:07
