Can you give them priority because we need them to enable HS400? +09:10 < wsa_> neg: or does the reset issue fix a set of problems I am currently unaware of? +09:10 < wsa_> morimoto: is it correct to not update BSP-ticket files older than 'bsp370'? +09:11 < morimoto> on what ? +09:11 < wsa_> in other words, I only update 'bsp370' now and consider the other ones "v4.x" outdated +09:11 < wsa_> periupport +09:11 < morimoto> My understanding is that basically we want to 100% done all ticket on periupport +09:12 < morimoto> if possible +09:12 < morimoto> next ver bsp380 (?) can be started on new tool +09:12 < morimoto> Is this good answer for you ? +09:12 < horms> morimoto: I think this is not a question about what to do, but rather what to track +09:12 < horms> Currently we have bsp70 4.14 and 4.9 tickets +09:12 < morimoto> Yes +09:12 < neg> wsa_: sure I can try and move it up on the list, my plan was to work on that after ELCE during the SDHI hacking days as that issue has the most unclear solution to me at this time +09:13 < horms> Can we assume that all relevant tickets are included in bsp370 and ignore the old 4.14 and 4.9 tickets because they are assumed to be duplicates +09:13 < wsa_> neg: ah, this is included in the "4tap" task? +09:13 < morimoto> If working for v4.x is too old or impossible, I think we can skip +09:13 < horms> Or do we need to keep tracking all bsp370 4.14 and 4.9 tickets +09:13 < horms> with all duplicates? +09:13 < morimoto> horms: Ohh, yes, I think so +09:14 < horms> ok, i think that was wsa_'s question +09:14 < wsa_> horms: thanks for the clarification. that was exactly what i meant +09:14 < horms> One thing on the BSP: I expect BSP 3.7.2 will be released today or tomorrow +09:14 < neg> wsa_: yes that is core problem of the 4-tap clock issue, maybe I should use a better description for the task, sorry about that +09:15 < wsa_> neg: ok, good +09:15 < shimoda> horms: "with all duplicates" means these tickets (bsp370, 4.14, 4.9) have duplicate commits? +09:16 < horms> shimoda: yes, maybe with different commit ids due to rebasing +09:16 < wsa_> neg: please note that Geert won't be at the SDHI hackfest (and probably not available by mail because it is a weekend). +09:16 < horms> shimoda: so its a bit of extra work to update the duplicate tickets +09:17 < wsa_> neg: so, some discussion beforehand might be helpful? +09:17 < neg> wsa_: I agree that is something to handle and as you suggest try to discuss beforehand with geertu +09:19 < wsa_> thanks +09:19 < geertu> wsa_: I'll be stuck in Edinburgh until my late afternoon flight +09:19 < wsa_> geertu: which day? +09:20 < geertu> wsa_: Saturday +09:21 * geertu has never been to Edinburh before, so there may be more interesting things to visit ;-) +09:21 < wsa_> good to know +09:21 < morimoto> horms: sorry maybe I answered strange things for you. +09:21 < wsa_> SDHI hackfest will not be in Edinburgh, though +09:21 < wsa_> but close +09:21 < neg> geertu: more interesting that solving clock divider problmes? What could it possibli be? :-) +09:22 < wsa_> I think we will see at "runtime", but let's plan for you having some sightseeing time in Edinburgh :) +09:22 < horms> morimoto: I'm fine with your answer.
