09:06 < geertu> Welcome to today's Core Group Chat
09:06 < geertu> Agenda:
09:06 < geertu> 1. Status Updates
09:06 < geertu> 2. Discussion Topics
09:06 < geertu> 3. PERIPERI BE Agenda
09:06 < geertu> Topic 1. Status updates
09:06 < geertu> A) What have we done since last time
09:06 < geertu> Jacopo started looking into the M3-N task and booted to console.
09:06 < geertu> Marek worked on the U-Boot platform conversion for R-Car Gen2 (Porter
09:06 < geertu> done).
09:06 < geertu> Shimoda-san continued evaluation of the M3-N IPMMU HW, which now works for
09:06 < geertu> VIN.
09:07 < geertu> Simon added soc nodes to R-Car Gen2 DTS files, and continued IPMMU
09:07 < geertu> integration.
09:07 < geertu> Geert fixed regressions in -next, upgraded firmware and U-Boot on
09:07 < geertu> Salvator-X(S), got QEMU+KVM working on arm64 (needs firmware with HYP mode,
09:07 < geertu> see https://elinux.org/R-Car/Virtualization), and started looking into GPIO
09:07 < geertu> pass-through using vfio-platform.
09:07 < geertu> EOF
09:08 < geertu> B) What we plan to do till next time
09:08 < geertu> Many Euro-members plan to enjoy PERIPERI BE and FOSDEM.
09:08 < geertu> Jacopo will start looking into PFC for M3-N.
09:08 < geertu> Marek will convert more R-Car Gen2 platforms to the new U-Boot, and start
09:08 < geertu> working on Stout after its arrival.
09:08 < geertu> Shimoda-san will discuss a plan to improve the IPMMU driver with
09:08 < geertu> Magnus-san.
09:08 < geertu> Simon will test CPUFreq/Z,Z2 Clock patches on BIG.little using Lager board
09:08 < geertu> to be borrowed from Wolfram, and is considering adding soc nodes to other
09:08 < geertu> DTSes.
09:08 < geertu> Geert will do more virtualization work (documentation, GPIO pass-through),
09:08 < geertu> and revisit in-kernel BD9571MWV DDR backup mode.
09:09 < geertu> EOF
09:09 < geertu> C) Problems we have currently
09:09 < geertu> None
09:09 < geertu> EOF
09:10 < geertu> That was quick ;-)
09:10 < neg> :-)
09:10 < geertu> Anything I missed, or that needs explanation?
09:11 < jmondi> I would have a question for morimoto-san, on Migo-R clocks, as it seems he and Magnus are the authors of that code
09:11 < jmondi> am I wrong Morimoto-san?
09:12 < morimoto> which clock ?
09:12 < jmondi> video_clk
09:12 < jmondi> it is said to be reduced to 10MHz for display panel issue, does this rings any bell to you?
09:12 < morimoto> Migo-R... I don't remember detail...
09:13 < jmondi> ok, I'll ping you offline maybe, don't want to hold the meeting for this
09:13 < morimoto> thanks
09:13 -!- dammsan [~dammsan@s214090.ppp.asahi-net.or.jp] has joined #periperi
09:13 < Marex> shimoda: any news on the RPC QSPI erase/write example please ?
09:13 < geertu> Topic 2. Discussion Topics
09:14 < morimoto> Marex: Now I'm working for export paper work for mini monitor
09:14 < Marex> morimoto: uh, sorry to make you suffer through that and thank you very much !
09:14 < Marex> shimoda: ^ you too
09:14 < morimoto> No problem, but this paper work will takes more time.
09:16 < Marex> I was hoping there would be some small RPC QSPI example, I don't really need the entire minimon, but having the whole thing might be nice too !
09:16 < shimoda> Marex: RPC QSPI erase/write example is in part of mini monitor code, so we have to finish the export paper work that Morimoto-san said
09:16 < Marex> aha, so that's why
09:16 < Marex> understood
09:17 < Marex> I'll see if I can get the SPI NOR access through GPIO bitbang during fosdem going at least
09:17 < Marex> as a stop-gap solution that is
09:18 < dammsan> Marex: please implement hyperflash gpio support =)
09:19 < geertu> dammsan: spi-gpio doesn't even do dual or quad mode yet
09:19 < Marex> dammsan: we have RPC HF support, doing it over GPIO would be painfully slow with no benefit
09:19 < geertu> should be fairly simple to add
09:19 < geertu> with GPIO [gs]et_multiple
09:19 < Marex> dammsan: plus, all the platforms that boot from HF that I have don't support GPIO on the HF pins :(
09:20 < Marex> it's only V3M and D3 that support that AFAIU
09:20 < Marex> M3/H3 cannot mux the RPC pins as GPIOs according to the documentation
09:20  * Marex would be happy to be proven wrong ...
09:21 < geertu> Marex: Remote access to D3 and V3m does exist...
09:22 < Marex> geertu: I know
09:22 < pinchartl> (hello)
09:22 < geertu> pinchartl: Hi
09:23 < geertu> pinchartl: You're earlier than wsa ;-)
09:23 < geertu> Marex: Not having GPIO muxes on the RPC pins is a security feature
09:24 < pinchartl> :-)
09:24 < Marex> geertu: not on V3M/D3 apparently
09:24 < geertu> Marex: Different target market segment
09:24 < Marex> :)
09:28 < pinchartl> as Wolfram isn't here yet should we start with multimedia ?
09:29 < Marex> pinchartl: give him 2 minutes ?
09:29 < Marex> in the meantime, I have one more question ...
09:30 < Marex> ... I have a spare M3SK, I'll take it to FOSDEM, anyone wants it ?
09:30 < geertu> M3SK = M3ULCB?
09:30 < Marex> jupp
09:30 < Marex> ... improved edition with mainline u-boot !
09:30 < jmondi> If nobody else wants it, I do :)
09:30 < geertu> Could you please check if it does PSCI system suspend/resume?
09:31 < jmondi> that would be useful for kingfisher expansion maybe
09:31 < Marex> jmondi: sold to this gentlemen !
09:31 < geertu> Does "reset" work from U-Boot?
09:31 < geertu> Does "reboot" work from Linux?
09:31  * Marex knocks the gavel
09:31 < pinchartl> jmondi: you'd need a kingfisher base board though
09:31 < jmondi> wait, maybe someone has more urgent things to do, afaik only pinchartl has been able to purchase a kingfisher expansion
09:31 < jmondi> pinchartl: it's not pluggable?
09:32 < Marex> geertu: drop me an email about it
09:32 < pinchartl> jmondi: it is, but you'd still need the board :-)
09:33 < jmondi> pinchartl: ah yes, but with a bit of patience I may be able to buy one, am I not?
09:33  * kbingham holds out for a condor with 8 fakra's on the same board :D
09:33 < morimoto> pinchartl: btw, did you receive KF ?
09:34 < pinchartl> morimoto: yes I did
09:34 < pinchartl> I have trouble paying it though
09:34 < morimoto> pinchartl: OK, sounds good
09:34 < pinchartl> I sent the money and the transfer was delayed
09:34 < pinchartl> my bank says the receiving bank in Japan is blocking the payment because they want to conduct additional verifications
09:35 < pinchartl> and Shimafuji says their bank just hasn't received the money
09:36 < horms> pinchartl: I initiate a transfer from inside Japan. Perhaps we can explore that option if you can't get yourself unstuck
09:37 < morimoto> pinchartl: sounds not good :(
09:37 < geertu> horms: And as soon as that one completes, pinchartl's will complete, too ;-)
09:38 < geertu> pinchartl: Anyway, you do have the board? Or will they send you the launch codes after receiving the money?
09:40 < pinchartl> horms: thanks. the money has already left my bank account though, so I'd want to make sure it comes back before sending it a second time :-)
09:40 < pinchartl> morimoto: I know :-(
09:40  * pinchartl dislikes banks
09:40 < morimoto> bit-coin :)
09:40 < horms> pinchartl: ack. i would want that oo
09:40 < horms> pinchartl: ack. i would want that too
09:40 < uli___> if it is any consolation, i've had such issues several times, and the money never gets lost
09:40 < uli___> but it can take a very long time to sort it out...

09:42 < geertu> So please go ahead!
