+09:31 < geertu> Welcome to today's Core Group Chat Meeting!
+09:31 < geertu> Agenda:
+09:31 < geertu> 1. Status Updates
+09:31 < geertu> 2. Discussion Topics
+09:31 < geertu> Topic 1. Status updates
+09:31 < geertu> A) What have we done since last time:
+09:31 < geertu> Moirmoto-san updated the Renesas tools (Yocto Maker, ROM writer, S4
+09:31 < geertu> Spider support) and started preparing Renesas Linux related work.
+09:31 < geertu> Shimoda-san reviewed R-Car S4 PFC patches.
+09:31 < geertu> Geert posted R-Car S4-8 pinctrl v2, sent pull requests for v5.18, tested
+09:31 < geertu> a patch series to repair swap over NFS, reviewed lots of patches, and
+09:31 < geertu> processed periject.
+09:31 < shimoday> pinchartl: thank you for the information. other vendors direction is good information :)
+09:32 < geertu> B) What we plan to do till next time:
+09:32 < geertu> Morimoto-san plans to do Renesas work.
+09:32 < geertu> Shimoda-san plans to submit a CCREE bug fix, follow the R-Car S4 "PWM"
+09:32 < geertu> direction, and prepare R-Car V4H initial support, R-Car S4 board
+09:32 < geertu> assignment, and RC21012 driver support for R-Car S4.
+09:32 < geertu> Geert plans to review more patches, and do BSP mining.
+09:32 < geertu> C) Problems we have currently:
+09:32 < geertu> Morimoto-san is worried about EuroPeri people from Russian attack.
+09:32 < geertu> Geert is worried by RZ/G2UL and RZ/Five sharing most of the part number.
+09:32 < pinchartl> shimoday: :-) not everybody is going full speed in that direction yet, it's the start of a movement. as always being among the first ones can bring challenges, but also opportunities
+09:32 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has quit [Remote host closed the connection]
+09:33 < geertu> pinchartl: leaders vs. followers
+09:33 < marex> moriperi: what's "Yocto" again ? :)
+09:33 < geertu> ---EOT---
+09:33 < geertu> Anything I missed?
+09:33 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has joined #periperi
+09:33 < marex> moriperi: are you looking for bitbake project setup tool like https://github.com/siemens/kas this instead maybe ?
+09:34 < moriperi> marex: It is tool to easy create Renesas Yocto BSP
+09:34 < marex> moriperi: https://kas.readthedocs.io/en/latest/userguide.html?module-kas.plugins.menu#module-kas.plugins.menu comes with kconfig based menu too recently ;-)
+09:35 < shimoday> pinchartl: i see
+09:35 < geertu> shimoday: Can you please remind me again what's RC21012?
+09:35 < shimoday> geertu: RC21012 is a clock generator, named VersaClock
+09:35 < marex> moriperi: look at that 'kas' tool, I think that's what you're trying to implement
+09:36 < patersonc[m]> moriperi: I'm not sure if KAS can handle the manual steps to copy the proprietary libs for the Renesas BSP. At least it didn't last time I looked. Everything else should be okay though
+09:36 < geertu> shimoday: OK, so it's Spider-specific, not related to S4 in se
+09:36 < marex> pinchartl: it probably can with a small python plugin
+09:36 < marex> patersonc[m]: ^
+09:36 < marex> the kconfig menu where you can implement e.g. board selection and feature on/off button is neat
+09:37 < shimoday> geertu: yes, it's on Spider
+09:37 < geertu> So Renesas jumped on the RISC-V train, and announced RZ/Five
+09:37 < patersonc[m]> marex: oooohhhh. May have to look again
+09:37 < patersonc[m]> Choo Choo
+09:37 < marex> patersonc[m]: see that 'kas menu' thing ... it's very recent and it surprised me pleasantly
+09:37 < geertu> Which is basically an RZ/G2UL with RISC-V CPU core and INTC instead of ARM and GIC
+09:38 < marex> patersonc[m]: for basic users, that's really easy to get started
+09:38 < moriperi> marex: patersonc[m]: thanks. I will check it
+09:38 < geertu> Not that dissimi;ar from R-Car M1A, which is M1S (SH) + ARM
+09:38 < geertu> dissimilar
+09:38 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has quit [Remote host closed the connection]
+09:39 < geertu> damm is scared of RISC-V?
+09:39 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has joined #periperi
+09:39 < geertu> Hence both RZ/GUL and RZ/Five are R9A07G043, but using different suffixes (U vs F)
+09:40 < patersonc[m]> Just to keep things "simple"
+09:41 < geertu> Now, we already started using r9a06g043-based compatible values for RZ/G2UL, and I think we should continue doing so.
+09:41 < damm> Nice to see
+09:41 < geertu> r9a07g043-based, ofc.
+09:41 < geertu> (one really has to use copy-'n-paste ;-)
+09:42 < geertu> While most I/O devices are the same on 'u and 'F, of course there may/will be some subtle differences in core components like CPG and SYSC
+09:42 < marex> moriperi: I sent you some further examples via PM, did you receive those ?
+09:43 < moriperi> marex: PM = private mail ?
+09:43 < wsa> that RZ/Five sounds nice
+09:44 < geertu> So I think we should try to identify the differences early on, if possible, and see if we can handle them easily.
+09:44 < marex> moriperi: private message , you might have another window in your irc client open now
+09:44 < geertu> I want to avoid needing a proliferation of r9a07g043u-based compatible values, with all the churn that brings.
+09:44 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has quit [Remote host closed the connection]
+09:44 < geertu> Do you agree?
+09:45 < moriperi> marex: oops, I didn't notice the one.
+09:45 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has joined #periperi
+09:45 < patersonc[m]> geertu: Yep
+09:46 < geertu> As initial documentation of RZ/Five is terse, and in Japanese, identification of the differences is non-trivial.
+09:49 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has quit [Remote host closed the connection]
+09:50 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has joined #periperi
+09:51 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has quit [Remote host closed the connection]
+09:52 < patersonc[m]> geertu: I'm told there will be a new manual due e/March
+09:52 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has joined #periperi
+09:53 < wsa> patersonc[m]: and when do we get boards? ;D
+09:53 < geertu> patersonc[m]: That's good news. So we don't have to hurry, as the v5.19 merge window for soc will close at B/May
+09:53 < geertu> wsa: You still don't have RISC-V boards? ;-)
+09:54 < patersonc[m]> wsa: I'm actually working on that, although it may be quicker to get from distis. Not sure on the timeline yet. Finding components for building platforms is _hard_
+09:54 < wsa> Nope, I only work with Renesas HW now <3
+09:54 < wsa> ;)
+09:55 < wsa> patersonc[m]: oh wow, it is really in the making... cool!
+09:56 < geertu> wsa: mass production in June, according to the press release
+09:56 < wsa> No hurry from my side, the boards I have around me have enough quirks still to be handled
+09:56 < geertu> Anything else to discuss?
+09:56 < patersonc[m]> wsa: Our team are actually the ones who make all the G2L* smarc platforms. So we get them first :P
+09:57 < wsa> geertu: "in the making" == paperwork to get boards to us
+09:57 < patersonc[m]> #madeinuk
+09:57 < kbingham> patersonc[m], Oh, that will be easy to import for me then ;-)
+09:57 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has quit [Remote host closed the connection]
+09:57 < wsa> heh, so this is export paperwork now as well
+09:57 < wsa> except for Kieran :D
+09:58 < geertu> kbingham: for you it will be, indeed...
+09:58 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has joined #periperi
+09:58 < wsa> kbingham has a nice lab...
+09:58 < wsa> remote lab
+09:59  * pinchartl plays Itsumo nando demo as a welcome waiting music for the MM meeting
+09:59 < geertu> Next meeting. So we have a special meeting planned on March 31?
+10:00 < geertu> Thanks for joining, and have a nice continued day!
