I'm tring hard for it now +10:38 < morimoto> If I can do *before* summer vacation, we can ship end of this week +10:38 < pinchartl> ok +10:38 < morimoto> If I couldn't, It will be after summer vacation, it will be 22th's week +10:38 < pinchartl> I will be away from home from the 18th to the 30 of August +10:39 < morimoto> Ohh.. +10:39 < geertu> Ship it to Toronto ;-) +10:40 < pinchartl> geertu: given that I'll be in Belgium and France, I don't think that would help +10:40 < horms> Probably it is not helpful, but if it is I'm happy to act as an intermediary +10:40 < geertu> pinchartl: Oh, you're skipping LinuxCon +10:41 < geertu> I'm in Belgium between 18th and 30th of August anyway +10:41 < pinchartl> :-) +10:42 < pinchartl> morimoto: so, there's no urgency for me. Kieran will also be back at the end of the month only +10:42 < pinchartl> you can thus ship the boards at end of August +10:42 < pinchartl> no need to rush, enjoy your summer vacation :-) +10:43 < shimoda> morimoto-san is now calling to someone +10:44 < shimoda> this seems related to the peper work :) +10:46 < morimoto> Sorry, it was shipment guy. +10:46 < morimoto> We try to ship board 11th from Renesas, but it seems shipment side is busy +10:46 < geertu> Last person is Laurent +10:47 < pinchartl> nothing to report for core +10:47 < pinchartl> no work done, no work to do, no issue :-) +10:48 < morimoto> Perfect !! +10:48 < geertu> pinchartl: Thank you! +10:49 < pinchartl> nyt on lounasaika ! +10:49 < pinchartl> (now is lunch time) +10:49 < geertu> Let's eat H3ULCB +10:49 < geertu> pinchartl: enjoy your lunch! +10:49 < morimoto> :P +10:49 < pinchartl> talk to you later +10:50 < neg> I have a question if it would be bad to send a patch to enable CONFIG_CGROUPS in shmobile_defconfig? +10:50 < geertu> So it seems Renesas/Cogent have a low-cost H3 board called H3ULCB +10:50 < neg> ohh my bad please go ahead with H3ULCB talk +10:50 < geertu> neg: No objection. It's what makes shmobile_defconfig boot on my koelsch +10:50 < horms> neg: I'm ok with that if there is a reason for it +10:51 < geertu> Although my personal koelsch config doesn' +10:51 < geertu> t hav it set +10:51 < horms> MY position on the H3ULCB patches is this: +10:51 < neg> horms: is i need it for systemd init and I keep forgeting to enable it and it bugs me a good reason? Other then that I have no real technical reason to wish to enable it :) +10:51 < horms> 1) I'm mostly ok with adding a board we can't test as its for an SoC that is already in mainline +10:51 < geertu> So in shmobile_defconfig, it seems to avoid the strange lock ups during boot, which I could also avoid by adding the right number of nop()s +10:52 < horms> neg: sounds good. systemd is standard on Debian these days. I would probably have the same problem if I updated userspace. And Debian is the defacto user-space test imho +10:52 -!- khiemnguyen [d2a0fca8@gateway/web/cgi-irc/kiwiirc.com/ip.210.160.252.168] has quit [Quit: http://www.kiwiirc.com/ - A hand crafted IRC client] +10:53 < neg> OK thanks I will send a patch enableing it then +10:53 < horms> 2) I'd like them to split up the patch to enable IP blocks one by one +10:53 < horms> 3) I'd prefer if any IP blocks not enabled on H3/Salvator-X were at the end of the patch-set +10:53 -!- khiemnguyen [d2a0fca8@gateway/web/cgi-irc/kiwiirc.com/ip.210.160.252.168] has joined #periperi +10:54 < horms> 4) I would value input from the group, especially Morimoto-san and Shimoda-san -> I think Renesas should be aware of this +10:54 < horms> --- thats about it from my side --- +10:54 < geertu> I agree with all four points +10:54 < geertu> 5) Can we get documentation? +10:55 < geertu> 6) Can we get access to a board (e.g. in Magnus' farm)? +10:56 < shimoda> geertu: at the moment, i don't have the board. +10:57 < morimoto> shimoda: we can have 1 or 2 boards. +10:57 < horms> shimoda: do you think some kind of discussion with e.g. Munakata-san would be best before adding the board to mainline? +10:57 < morimoto> Maybe we will ask to Magnus about remove-access ? +10:59 < horms> I think that would be ideal +11:00 < morimoto> horms: about discussion with Munakata-san, maybe no discussion is needed, but we will re-check +11:00 < horms> Thanks! +11:01 < geertu> That's good to hear. +11:01 < geertu> I assume documentation will follow, too? +11:02 < morimoto> depends on which documentation. "board" documentation ? +11:02 < morimoto> you can get it from elinux on some board. (I don't know which board...) +11:02 < geertu> morimoto: Yes, e.g. schematics, so we can review the DTS +11:03 < geertu> morimoto: Not for H3ULCB AFAIK (porter and silk you can) +11:03 < morimoto> schematics is a little bit difficult. +11:03 < morimoto> I can say case-by-case +11:04 < horms> well, probably anything for the H3ULCB would be helpful +11:05 < horms> but if there is nothing available +11:05 < horms> we can just trust Cogent +11:05 < morimoto> hmm... +11:07 < khiemnguyen> for Porter or Silk, if we buy the boards, I think the schematics files are available in the CD. +11:10 < geertu> khiemnguyen: For porter and silk, there are links to the schematics on the eLinux wiki. You need to register with Renesas to access the links, though. +11:11 < khiemnguyen> I think H3ULCB will be the same, but we need to wait till next year ? +11:14 < horms> Ok, sounds like we should wait +11:15 < shimoda> about the documentation of H3ULCB, i will ask Munakata-san or Ito-san +11:15 < shimoda> if no doc, we should wait +11:17 < geertu> shimoda: ok, thx! +11:23 < morimoto> Is meeting finished ?? +11:24 < uli___> not sure :) +11:24 < geertu> Sorry, too distracted by SoW paperwork issues... +11:25 < geertu> Yes, unless someone has something to add, I think the meeting is finished +11:25 < neg> I would like to know if there is any core task I can start to work on, but maybe we can take that my mail :-) +11:26 < morimoto> OK, thanks. +11:26 < morimoto> geertu: please enjoy your paperwork :) +11:29 -!- morimoto [~user@relprex2.renesas.com] has left #periperi ["ERC Version 5.3 (IRC client for Emacs)"] +11:31 < geertu> neg: yes, email please +11:31 < geertu> Thanks for joining! |
