+09:07 < geertu> Welcome to today's Core Group Meeting!
+09:07 < geertu> Agenda:
+09:07 < geertu> 1. Status updates
+09:07 < geertu> Let's give the new format a try
+09:07 < geertu> A) What have I done since last time
+09:07 < geertu> B) What I plan to do till next time
+09:07 < geertu> C) Problems I have currently
+09:07 < geertu> D) Posted/Accepted bugfix patches
+09:08 < geertu> First is Shimoda-san
+09:08 < shimoda> yes
+09:08 < shimoda> A)
+09:08 < shimoda>  - prepare IPMMU workaround patch
+09:08 < shimoda>   - but I found the IPMMU driver on latest iommu repo could not work correctly
+09:08 < shimoda>     (even if the workaround patch is not applied).
+09:08 < shimoda> B)
+09:08 < shimoda>  - I will submit a workaround patch after the IPMMU issue is resolved by Magnus-san
+09:08 < shimoda> C)
+09:08 < shimoda>  - How to handle the following task? BSP team would like to add such a code
+09:08 < shimoda>    because they have an issue that is related to this feature.
+09:08 < shimoda>    https://patchwork.kernel.org/patch/9557691/
+09:09 < shimoda> D) fix sh-sci patch about race condition between serial console and dma
+09:09 < shimoda> fix usb1.1 suspend resume issue
+09:09 < geertu> BTW, thanks for the patch, I could reproduce the issue on Koelsch
+09:09 < shimoda> -- EOT --
+09:10 < geertu> Thank you, Shimoda-san
+09:10 < geertu> Next is Niklas
+09:11 < neg> A) Nothing - No Core task
+09:11 < neg> B) Nothing - No Core task
+09:11 < neg> C) Figure out how/when to handle core task 'Renesas R-Car SYS-DMAC Slow Mode and Priority Handling Prototyp'
+09:11 < neg> D) None
+09:12 < neg> eot
+09:13 < geertu> neg: If you find time for C, perhaps it's more worthwhile to look into Shimoda-san's C?
+09:14 < neg> geertu: sure if that is higer prio I be happy to look in to that when I get time
+09:14 < geertu> ok, thx...
+09:14 < geertu> Thank you Niklas
+09:14 < geertu> Next is Morimoto-san
+09:14 < morimoto> OK
+09:15 < morimoto> A = B = C (= D) = NULL
+09:15 < morimoto> EOT
+09:15 < geertu> Thank you Morimoto-san
+09:15 < geertu> Next is Marek
+09:16 < Marex> A = B = C = D = NULL
+09:17 < geertu> Thank you Marek
+09:17 < geertu> Next is Magnus
+09:17 < Marex> there was one external bugfix for GyroADC driver
+09:17 < dammsan> [5~I'm also mainly NULL
+09:17 < Marex> oops
+09:17 < dammsan> however for C I wonder how to proceed with the r8a7796 DT binding
+09:18 < dammsan> for IPMMU
+09:18 < dammsan> regarding B I hope to have an IPMMU patch stack refresh ready tomorrow
+09:18 < dammsan> EOF
+09:19 < geertu> dammsan: As Rob reviewed the r8a7795 upon Laurent's request, we should ping Jörg Rödel
+09:20 < geertu> s/sr8a7795/accepted r8a7795 binding/
+09:21 < dammsan> ok will do
+09:21 < geertu> Thank you Magnus
+09:21 < dammsan> thanks
+09:21 < geertu> Next is Laurent
+09:22 < geertu> pinchartl is away: Gone
+09:22 < geertu> Next is Jacopo
+09:23 < jmondi> here I am
+09:23 < jmondi> A)  - Posted RZ/A1 PFC and GPIO controller patches
+09:23 < jmondi> B) - Resend after reviews and have that driver merged
+09:23 < jmondi> C) = D) = None
+09:23 < jmondi> --- eof ---
+09:24 < jmondi> Chris wrote me offline he's going to test the pincontroller patch for RZ/A1 in these days
+09:24 < jmondi> I hope to have his tested-by before sending v2
+09:25 < jmondi> that's all!
+09:25 < geertu> Thank you Jacopo
+09:25 < geertu> Next is Geert

+09:26 < geertu>       - DMA_ATTR_SKIP_CPU_SYNC is in
+09:26 < geertu>       - I expect DMA_ATTR_FORCE_CONTIGUOUS to go in soon (unless the
+09:26 < geertu>         ARM64 maintainers want an upstream user first)
+09:26 < geertu>       - Related IOMMU and DMAC fixes
+09:26 < geertu>   - Suspend-to-Idle RFC patches:
+09:26 < geertu>       - Everything NAKed
+09:26 < geertu>       - Short story: use "echo s2idle > /sys/power/mem_sleep" if you
+09:26 < geertu>         want to use other wake-up sources

+09:26 < geertu>       - Complete R-Car H3 ES2.0 work
+09:26 < geertu>       - Update patches to enable more CPU cores on R-Car H3 and M3-W
+09:27 < geertu> C)
+09:27 < geertu>       - Had to drop IPMMU support from last renesas-drivers release
+09:27 < geertu> D)
+09:27 < geertu> clk: renesas: cpg-mssr: Migrate to CLK_IS_CRITICAL (v4.11)
+09:27 < geertu> arm64: Use __pa_symbol for empty_zero_page (v4.11)
+09:27 < geertu> drivers: firmware: psci: Use __pa_symbol for cpu_resume (v4.11)
+09:27 < geertu> net: phy: leds: Clear phy_num_led_triggers on failure (v4.10)

+09:27 < geertu> arm64: kernel: Update kerneldoc for cpu_suspend() rename
+09:27 < geertu> EOT
+09:28 < neg> fwiw, I think your 'Suspend-to-Idle RFC patches' where nice and sorry about it beeing NAKed
+09:28 < dammsan> yeah same here
+09:28 < dammsan> ARM ppl are not being very forward thinking there IMO
+09:29 < dammsan> but hey
+09:29 < geertu> Yeah, it was a bit disappointing...
+09:29 < dammsan> yeah..
+09:30 < geertu> At least people can keep on using "echo mem > /sys/power/state", if they did "echo s2idle > /sys/power/mem_sleep" before
+09:30 < geertu> Which also means that we can start working on Wake-on-LAN for RAVB ;-)
+09:31 < neg> :-)
+09:31 < geertu> There's also some work to be done in our PSCI implementation. SYSTEM_OFF should save much more power
+09:32 < dammsan> Prediction: Constant need for improvement
+09:33 < geertu> From skimming through the "C" items, we need some resource to care for RCAR-DMAC?
+09:34 < dammsan> unless someone else wants to do it
+09:34 < dammsan> i can add it to my todo list
+09:34 < dammsan> need to cover for simon for some back porting anyway
+09:35 < dammsan> nice with something semi-techinical aside from the IPMMU
+09:35 < geertu> That would be great! (but please make IPMMU "work" again first ;-)
+09:35 < dammsan> yep, that's prio #1
+09:35 < neg> If nothing else starting 20th of march (probobly a bit erlier) I got an intense base contract perido where I can do Core work
+09:35 < geertu> That went smooth... Do we have anything else to discuss?
+09:36 < jmondi> I also need a task for Core after the RZ pinctrl
+09:36 < dammsan> jmondi: did you manage to run Linux on the pink RZ board?
+09:36 < jmondi> I need a JTAG programmer first
+09:36 < dammsan> buy a flyswatter or similar
+09:37 < dammsan> ulrich would know what to get
+09:37 < jmondi> and chris suggested me to substitute the flash chip on the board
+09:37 < jmondi> whith involves un-soldering/soldering SMD chips
+09:37 < Marex> jmondi: or replace the flash chip with an FPGA emulator :)
+09:37 < Marex> (did that ... worked)
+09:37 < jmondi> Marex: like what?
+09:37 < dammsan> jmondi: do you have schematics?
+09:38 < jmondi> only the public available ones
+09:38 < jmondi> so no
+09:38 < geertu> jmondi: FWIW, I have a Flyswatter2
+09:38 < jmondi> :)
+09:38 < jmondi> I was looking at some J-Link
+09:38 < pinchartl> geertu: /me is back
+09:38 < Marex> jmondi: flyswatter2 is great
+09:38 < jmondi> mainly for open-ocd compatibility
+09:38 < Marex> jmondi: and it works with openocd real well
+09:38 < jmondi> that's great then
+09:39 < dammsan> geertu: did ulrich exclude himself from core? if not then upstream openocd support would be good
+09:39 < geertu> jmondi: This is GR-PEACH, right? I do have schematics
+09:39 < jmondi> ah nice! http://tincantools.com/wiki/Flyswatter2
+09:39 < dammsan> geertu: can you share the schematics?
+09:39 < jmondi> it's GR-PEACH, yeah
+09:40 < jmondi> $ls
+09:40 < jmondi> GR-Peach-Schematics.pdf
+09:40 < geertu> I've ordered mine from http://www.watterott.com/de/Flyswatter2 (in stock again!)
+09:40 < jmondi> so I have them as well, I wonder where I got them from :/
+09:40 < geertu> https://www.core.co.jp/product/m2m/gr-peach/pdf/history/gr-peach_circuit_e.pdf
+09:41 < geertu> pinchartl: Any A/B/C/D to contribute to the meeting?
+09:41 < dammsan> excellent thanks
+09:42 < jmondi> I'm buying that flyswatter right away then ;)
+09:43 < pinchartl> geertu: no core task, so no :-)
+09:45 < dammsan> pinchartl: did you discuss the PMIC bits with Marex?
+09:45 < dammsan> i mean regarding the documentation
+09:47 < Marex> dammsan: I saw some rudimentary driver link posted by geertu
+09:47 < dammsan> in the same nice way that the versaclk driver is upstream now
+09:47 < dammsan> it would be great with a pmic driver upstream
+09:47 < pinchartl> dammsan: no, I haven't. if there's a need for documentation I think it can be found in a dark corner somewhere. I'll check that
+09:48 < dammsan> thanks
+09:48 < Marex> hehe
+09:48 < geertu> morimoto: you have the PMIC docs?
+09:48 < morimoto> Yes. I have.
+09:48 < morimoto> But we can't send it to non-Renesas
+09:49 < morimoto> Because of special NDA
+09:49 < dammsan> so if we can't do Gen3 PMIC then begin with Gen2 PMIC makes sense?
