Core-chat-meeting-2018-01-09

09:37 < geertu> Welcome to today's Core Group Chat Meeting
09:37 < geertu> Agenda:
09:37 < geertu> 1. Status updates
09:37 < geertu> 2. Core additional tasks for Q1/2018
09:37 < geertu> 3. Discussion Topics
09:37 < geertu> Topic 1. Status updates
09:37 < geertu> A) What have we done since last time
09:37 < geertu> Marek worked on HS200 for U-Boot again, assumed to go in after the 2018.01
09:37 < geertu> release.
09:37 < geertu> Shimoda-san continued evaluation of the M3-N IPMMU HW.
09:37 < geertu> Simon fixed and merged Gen3 no-reg warnings, and addressed review for the
09:37 < geertu>  Z/Z2/CpuFreq patches for Gen3.
09:37 < geertu> Ulrich sent ZG clock support for M3-W.
09:37 < geertu> Geert worked on additional tasks, prepared for the meeting before FOSDEM,
09:37 < geertu> sent clk and pfc pull requests, investigated a severe arm64 bug, tried
09:37 < geertu> Marek's new U-boot binary, and started looking into QEMU+kvm virtualization
09:37 < geertu> on arm64.
09:38 < geertu> (if anything is missing, please scream)
09:38 < geertu> B) What we plan to do till next time
09:38 < geertu> Marek will work on upstreaming Gen2 U-Boot rework.
09:38 < geertu> Shimoda-san will continue evaluating M3-N IPMMU HW.
09:38 < geertu> Simon will check Z2 clock handling for little CPUs on resume.
09:38 < geertu> Geert will do more virtualization work, try to build Marek's new U-Boot,
09:38 < geertu> and revisit in-kernel BD9571MWV DDR backup mode.
09:39 < geertu> C) Problems we have currently
09:40 < geertu> Simon lacks physical access to Lager board to set s2ram of little CPUs.
09:40 < geertu> Geert has issues with R-Car Gen3 firmware booting Linux in EL1 instead of
09:40 < geertu> HYP mode, precluding kvm.
09:40 < pinchartl> (I'll be back in 15 minutes, nothing to report for core)
09:40 < geertu> (in the mean time, Marek sent me firmware that should enable HYP mode, thx)
09:42 < geertu> Regarding Lager, does it need special firmware to enable 8 CPU cores? The one in Magnus' farm boots the big cores only
09:43 < shimoda> geertu: about 8 cores booting, i will ask someone
09:43 < wsa_> I can bring my Lager to Brussels if that helps and is not too late
09:44 < geertu> horms: Your particular issue is _local_ access to Lager, as the osdr wiki says you have a Lager (in Kobe)?
09:45 < horms> geertu: ues, that is correct
09:45 < horms> for paperwork reasons I left it there
09:45 < horms> I am wondering if anyone attending the Brussels session might bring a board
09:46 < wsa_> heh
09:46  * wsa_ waves again
09:46 < geertu> horms: Is the issue doing remote wakeup? You may get sufficiently far with /sys/power/pm_test
09:47 < horms> That is one issue. The other is upgrading the fw.
09:47 < geertu> OK, fw is more complicated
09:48 < horms> I can probably arrange to upgrade the fw somehow, f.e. by having the board sent to HQ, but its not entirely risk-free
09:48 < geertu> Sure, I understand
09:49 < geertu> So Wolfram's offer may be the simplest solution (depending on how much time is needed)
09:49 < geertu> Topic 2. Core additional tasks for Q1/2018
09:49 < geertu> To the best of my knowledge, the following tasks have been issued for 2018 Q1 phase 1:
09:49 < geertu>   - U-Boot for R-Car Gen2 DM and DT conversion (Marek)
09:49 < geertu>   - QEMU+KVM on ARM64 and GPIO Pass-Through Prototype (Geert)
09:50 < horms> geertu: wsa_: yes, I think so. I can probably do preliminary testing in an hour or so. And then we can assess the next move.
09:51 < geertu> More tasks for 2018 Q1 phase 2 to be decided later...
09:51 < geertu> horms: OK
09:51 < horms> In news just in: I will likely push BSP v3.6.0 on Friday afternoon
09:51 < geertu> Topic 3. Discussion Topics
09:51 < geertu> (and announcements? ;-)
09:52 < geertu> Looking forward to the new BSP!
09:54 < geertu> morimoto: shimoda: Anything from the Renesas side? Are you happy (besides for holidays being over ;-)?
09:56 < shimoda> geertu: nothing from my side :)
09:57 < pinchartl> (back)
09:58 < morimoto> geertu: nothing too
09:58 < geertu> Anyone/anything else?
09:59 < neg> Only if there is any preparations needed for meetings or other activities during FOSDEM
10:00 < geertu> Make sure to attend Jacopo's, Marek's, and my presentations ;-)
10:00 < geertu> Anyone else who's presenting at FOSDEM?
10:01 < wsa_> hmm, i don't the ULCB COM Express type connector 440pin will be of much help :(
10:01 < neg> Hum are not two of those at the same timeslot :-)
10:01 < geertu> neg: Yes they are :-(
10:01 < geertu> neg: Live-streaming it is, multiple VIN inputs?
10:02 < geertu> wsa_: Soldering wires to random components indeed sounds easier
10:02 < geertu> Unless Uli makes COM Express breakout boards?
10:02 < geertu> uli___: ^
10:02 < uli___> i'm not familiar with that connector, but it sounds horrible so far... :)
10:02 < wsa_> ack
10:03 < geertu> So, thanks for joining, and have a nice continued day!
