+09:41 < geertu> Welcome to today's Core Group Meeting
+09:41 < neg> thanks wsa_
+09:41 < geertu> Agenda:
+09:41 < geertu> 1. Status updates
+09:41 < geertu> 2. Discussion Topics
+09:41 < geertu> Topic 1. Status updates
+09:41 < shimoda> neg: about v3m thermal, it's also the same with d3
+09:41 < geertu> I'll replay the reporting
+09:41 < geertu> A) What have I done since last time
+09:42 < geertu>   Geert:
+09:42 < geertu>     - Enabled INTC-EX on R-Car H3 ES2.0, M3-W, and D3 (incl. pinctrl for
+09:42 < geertu>       H3 and M3-W),
+09:42 < geertu>     - Sent patches to enable BD9571MWV backup mode from sysfs,
+09:42 < geertu>     - Sent patches to add missing CPU clocks,
+09:42 < geertu>     - Sent v2 of renesas_defconfig,
+09:42 < geertu>     - Sent v3 of cpg-mssr suspend/resume,
+09:42 < geertu>     - Sent v2 of sh-pfc suspend/resume,
+09:42 < geertu>     - Sent first part of fixes for genpd for wake-up devices (network 
+09:42 < geertu>       drivers).  
+09:42 < geertu>   Jacopo:
+09:42 < geertu>     - More patches for Peach DTS (clock and timers, ethernet now working)
+09:42 < geertu>   Marek (U-Boot):
+09:42 < geertu>    - Got ACK on becoming SH co-maintainer to expedite patch acceptance
+09:42 < geertu>    - Posted SDR104/HS200 patches
+09:42 < geertu>    - Posted V2 and V3 of xHCI support for Gen3 and got ACK on it
+09:42 < geertu>    - Implemented D3 Draak and V3M Eagle board support
+09:42 < geertu>        - PFC, clock, DTS, board support are in place
+09:42 < geertu>        - untested yet due to HW access issues, but it compiles
+09:42 < geertu>   Niklas:
+09:42 < geertu>     - Sent "[PATCH v3] thermal: rcar_gen3_thermal: fix initialization
+09:42 < geertu>       sequence for H3 ES2.0" and it was picked up.
+09:42 < geertu>   Shimoda:
+09:42 < geertu>     - Prepared M3-N Salvator-X board for remote access.
+09:42 < geertu>     - Talked BSP team about MSIF lock driver.
+09:42 < geertu>     - Submitted the following patch(es):
+09:42 < geertu>         - arm64: dts: renesas: salvator-common: add dr_mode property for
+09:42 < geertu>           USB2.0 channel 0
+09:42 < geertu>   Simon:
+09:42 < geertu>     - Reposted CPUFreq patches; recieved futher review
+09:42 < geertu>     - Rebased r8a7795 IPMMU DTS patchset
+09:42 < geertu> B) What I plan to do till next time
+09:42 < geertu>   Geert:
+09:42 < geertu>     - Attend ELCE and DT Workshop (Thursday)
+09:42 < geertu>     - Lead DT Workshop discussion on generic bindings,
+09:42 < geertu>     - Fix genpd for wake-up devices, part two (interrupt routing).
+09:42 < geertu>   Marek (U-Boot):
+09:42 < geertu>     - Work on testing V3M Eagle remotely
+09:42 < geertu>   Niklas:
+09:42 < geertu>     - If dependencies for the rest of the thermal patches (CPUFreq) gets
+09:42 < geertu>       picked up, rebase and resend the cpu cooling patches.
+09:42 < geertu>   Shimoda:
+09:42 < geertu>     - Add usb3.0 phy device node for r8a779[56].dtsi.
+09:42 < geertu>   Simon:
+09:42 < geertu>     - Address review of CPUFreq patches
+09:42 < geertu>     - Test and post IPMMU patches
+09:43 < geertu> C) Problems I have currently
+09:43 < geertu>   Niklas:
+09:43 < geertu>     - No hardware to test the thermal calibration from registers on. V3M
+09:43 < geertu>       uses different thermal hardware so it won't help. Plan is to hold
+09:43 < geertu>       on to the patches until they can be tested.
+09:43 < geertu>     - Not sure if we have plan for V3M thermal driver (maybe this is for
+09:43 < geertu>       IO?)
+09:43 < geertu> I think we covered this?
+09:43 < geertu>   Shimoda:
+09:43 < geertu>     - R-Car D3 Draak doesn't have any PMICs. So, it cannot do reboot,
+09:43 < geertu>       shutdown, suspend and resume.
+09:43 < geertu>     - Could upstream team suggest other solutions to BSP team?
+09:44 < geertu> Draak can reboot using the RWDT watchdog, which is already enabled
+09:44 < horms> Marek: is that SH or SD maintainer?
+09:45 < Marex> horms: SH
+09:45 < horms> Ok, as in SuperH ?
+09:45 < Marex> horms: actually rcar/rmobile, but the tree is called u-boot-sh
+09:45 < Marex> horms: legacy naming
+09:45 < geertu> For shutdown, you can use the standard "poweroff" command. Linux will put all devices to sleep. No idea what it will do when PSCI is called.
+09:45 < horms> Marex: ack
+09:45 < shimoda> about thermal, d3 spec is similar with gen2. so, power management team of bsp will use gen2 code to support d3.
+09:45 < Marex> horms: I can apply my own patches and be in complete control again, yay
+09:46 < horms> :)
+09:46 < geertu> For suspend/resume, you can use s2idle, with whatever wakeup source supported by Linux
+09:46 < neg> shimoda: thanks for the v3m/d3 hardware info
+09:46 < shimoda> neg: you're welcome!
+09:46 < geertu> s2ram will call into PSCI if PSCI advertises suspend support. No idea what will happen afterwards, or if there's a way to wakeup.
+09:47 < geertu> shimoda: Do you know the details about PSCI on Draak?
+09:47 < wsa_> i used to have a patch to reboot via WDT. I dropped it because of PSCI. I can try to dig it out if desired. (It was not rocket science anyhow ;))
+09:48 < shimoda> geertu: I don't know. so, I will ask IPL team
+09:48 < geertu> Hmm, we don't delcare PSCI support for Draak in DTS yet
+09:48 < geertu> s/delcare/declare/
+09:48 < Marex> wsa_: does gen3 have a wdt ot wake it up ie. with rtcwake ?
+09:48 < geertu> So everything should work fine ;-)
+09:49 < horms> I assume it would be described in DT. But if so should it also be described in DT for SoCs that also support other reset mechanisms
+09:49 < geertu> I haven't tested suspend/resume on Draak yet, due to remote access.
+09:50 < horms> Is there a non-local solution to that problem?
+09:50 < geertu> s2idle and Wake-on-LAN should work now we have ravb support
+09:51 < horms> thanks
+09:51 < geertu> shimoda: Does that answer your question?
+09:51 < wsa_> Marex: I don't get your question probably, I'd say WDT != RTC, but you know that, of course
+09:51 < Marex> wsa_: errrr, 4 hours of sleep does this to me, sorry
+09:51 < geertu> wsa_: On Gen2, the PMIC (DAxxxx) has an RTC
+09:52 < Marex> wsa_: I meant rtc indeed
+09:52 < shimoda> geertu: yes. thanks!
+09:52 < geertu> On Salvator-X, there's no RTC
+09:52 < geertu> shimoda: Speaking about remote access, you have prepared an M3-N board?
+09:53 < shimoda> geertu: i gave Magnus-san the board. and magnus-san is preparing it for remote access now I heard
+09:54 < dammsan> yep
+09:54 < geertu> Good (I thought he was on a plane ;-)
+09:54 < geertu> dammsan: Do you know what's wrong with TFTP timeouts on Eagle? It became unbootable due to that
+09:55 < Marex> geertu: apparently fix is work-in-progress
+09:55 < Marex> geertu: I got email about it this morning
+09:55 < dammsan> geertu: i heard about eagle/draak issues, will replace the alix node with a different one
+09:56 < shimoda> geertu: ah, i also saw such behavior (a lot of timeout happen and retry the tftp forever) on h3ulcb today.
+09:56 < geertu> dammsan: Thx! (replacing whole nodes in case of issues feels like a real datacenter ;-)
+09:57 < shimoda> so i intended to ask magnus-san later :)
+09:57 < geertu> Topic 2. Discussion Topics
+09:57 < geertu> Does anyone have other topics to discuss?
+09:58 < shimoda> nothing from me
+09:58 < Marex> no
+10:00 < geertu> Who will be at ELCE next week?
+10:00 < geertu> https://osdr.renesas.com/projects/linux-kernel-development/wiki/Miniperi-2017-10 looks a bit sparse
+10:00 < jmondi> I didn't know about this link!
+10:00 < jmondi> filling in details now!
+10:01 < neg> Same, I will fill in details in a few min as to not overwrite jmondi update :-)
+10:02 < geertu> neg: Which wiki did you update according tou your email?
+10:02 < geertu> s/tou/to/
+10:02 < neg> geertu: but yes I will be there, and I also signed up for the DT workshop (hoping it won't collide with the media meetings) :-)
+10:02 < geertu> neg: DT is all day
+10:02 < neg> geertu: the 'memeber info' page related to upcomming holidays
+10:03 < horms> oh, that reminds me; I am taking a holiday next week. Sorry, no ELCE for me.
+10:03 < horms> Timing clash with conference and school holidays :(
+10:04 < neg> geertu: OK I will attand as much as possible of the DT workshop then :-)
+10:04 < Marex> geertu: ELCE ? me ... and if anyone of the group needs assistance or gets stuck in some weird ditch, let me know ...
+10:04 < geertu> horms: In BE, the school holidays are one week later ;-)
+10:04 < geertu> uli__: Will you be at ELCE?
+10:04 < horms> They are tagered in NL. But my son goes to an independent school and they have their own schedule (maybe the UK one?)
+10:04 < uli__> i'll be there to say hi, but not to attend the conference. any suggestions on when would be best? (matthias brugger wants to meet up between 23 and 26, so it would be one (or two) of these days
+10:05 < uli__> )
+10:05 < geertu> uli__: Tuesday Marex Party Time?
+10:05 < uli__> sounds promising :)
+10:06 < pinchartl> sorry, I'm late
+10:06 < pinchartl> I got stuck in traffic
+10:07 < pinchartl> (let me know when I can start with multimedia)
+10:07 < neg> pinchartl: welcome
+10:08 < geertu> I think we're finished.
+10:08 < geertu> Thanks for joining!
+10:08 < geertu> One thing: next meeting?
+10:08 < geertu> Does it make sense to have next one right after ELCE, or shall we postpone by one week?
+10:09 < pinchartl> I propose postponing by one week
+10:09 < Marex> pinchartl: +1
+10:09 < pinchartl> I couldn't join a meeting the week right after ELCE anyway
+10:09 < geertu> wsa_: Still there?
+10:10 < wsa_> yup
+10:10 < wsa_> postponing
+10:10 < wsa_> yes
+10:11 < Marex> hm, YPDD, OpenWRT summit, DT workshop, all in one day ... sigh
+10:11 < geertu> OK.
+10:11 < geertu> pinchartl: The mic is yours
