+09:07 < wsa> okay, let's start the meeting now
+09:08 < jmondi> wsa: :)
+09:08 < Marex> heh
+09:08 < wsa> here are the collected IO reports
+09:08 < wsa> A - what have I done since last time
+09:08 < wsa> ------------------------------------
+09:08 < wsa> Geert
+09:08 < wsa> : tested TPU on Salvator-XS, and investigated sh_eth and SPI EEPROM regressions
+09:08 < wsa> Kaneko-san
+09:08 < wsa> : addressed review of thermal calculation update for Gen3
+09:08 < wsa> Niklas
+09:08 < wsa> : retested SDHI PM issues using Geerts instructions and figured them out,
+09:08 < wsa>   worked on clarifying the cooling-states for the Gen3 thermal driver
+09:08 < wsa> Shimoda-san
+09:08 < wsa> : sent a patch series to improve performance by using IOMMU, measured SDHI & USB
+09:08 < wsa>   SSD performance to verify the CPU load, reviewed patches about USB & DMA
+09:08 < wsa> Simon
+09:08 < wsa> : updated patch to avoid using TX delay mode on E3/D3, sent new version of
+09:08 < wsa>   rcar_thermal patch to update calculation foromula, sent new versiof of patch
+09:08 < wsa>   to add thermal zone to support IPA on H3, tested thermal calculation update
+09:08 < wsa>   for Gen3
+09:08 < wsa> Ulrich
+09:08 < wsa> : sent RAVB patch to implement MTU change while device is up
+09:08 < wsa> Wolfram
+09:08 < wsa> : reviewed first upstream backend of i2c slave interface, sent out final version
+09:08 < wsa>   for watchdog_init_timeout refactoring, fixed a reported bug about not-ratelimited
+09:08 < wsa>   error messages with suspended I2C adapters, prepared proposal for Linux Plumbers,
+09:08 < wsa>   took over maintainership for the i2c-gpio driver, reviewed Shimoda-san's patches
+09:08 < wsa>   for SDHI and IOMMU, minor patch review for Renesas Europe
+09:08 < wsa> B - what I want to do until next time
+09:08 < wsa> -------------------------------------
+09:08 < wsa> Kaneko-san
+09:08 < wsa> : wants to continue with thermal calculation update for Gen3
+09:08 < wsa> Niklas
+09:08 < wsa> : wants to finish analyses of Geerts issues with the SDHI  PM patch
+09:08 < wsa> Shimoda-san
+09:08 < wsa> : wants to update SDHI with IOMMU patches, and continue to discuss about
+09:08 < wsa>   RZ/A2 USBHS support
+09:08 < wsa> Simon
+09:08 < wsa> : wants to address feedback for above thermal patches, and follow up on RAVB
+09:08 < wsa>   on E3/D3
+09:08 < wsa> Wolfram
+09:08 < wsa> : wants to investigate SDR104 regression with SDIO, handle 'arbitration lost' better
+09:08 < wsa>   with the IIC core
+09:08 < wsa> C - problems I currently have
+09:08 < wsa> -----------------------------
+09:08 < wsa> Kaneko-san
+09:08 < wsa> : is looking for upporting candidates
+09:08 < wsa> Simon
+09:08 < wsa> : doesn't know how to handle 100MBit speed limit on D3/E3 because he cannot
+09:08 < wsa>   test the alternative solution (PHY settings)
+09:08 < wsa> Wolfram
+09:08 < wsa> : has been knocked out by an illness for nearly two weeks
+09:08 < wsa> fire away any comments or questions
+09:09 < wsa> horms: about your upporting question for Kaneko
+09:09 < wsa> unless we get a new ticket file (bsp395?), IO is all done/assigned with upporting
+09:09 < wsa> I think only MM has upporting tasks left
+09:10 < wsa> dunno if that is suitable for Kaneko
+09:10 < wsa> I keep looking around for other non-upporting tasks, though
+09:11 < wsa> geertu: I rediscovered a clock related question to you, it's about the WDT
+09:11 < wsa> https://patchwork.kernel.org/patch/10900571/
+09:11 < wsa> If you have some time...
+09:11 < horms> wsa: ack, thanks
+09:12 < wsa> neg: can you give a quick summary what the two issues were which you found with the MMC clock imbalance thing?
+09:12 < wsa> The mails confused me a little, because I read one was MMCIF which is != SDHI?
+09:12 < geertu> wsa: Thanks, will reply
+09:13 < wsa> geertu: thanks!
+09:13 < pinchartl> horms: there are BSP patches not addressed yet for MM, we can have a look at that during the MM part of this meeting
+09:14 < wsa> neg: ?
+09:14 < wsa> neg: fallen asleep on the sofa again? ;)
+09:15 < horms> pinchartl: thanks. unfortunately I have to leave this meeting soon. perhaps we can chat in the not too distant future
+09:15 < pinchartl> sure, works for me
+09:15 < wsa> horms: do you still have a few minutes to talk about the RAVB D3/E3 testing issue?
+09:15 < horms> yes, i have a few minutes
+09:16 < wsa> so, we got some magic values from the BSP team for the PHY which could add this "delay mode"
+09:16 < wsa> but we don't have a way to test that?
+09:16 < horms> yes, that is correct
+09:16 < horms> I can try the values and see if ethernet works
+09:17 < horms> But I don't have a test case for the unreliable gigabit communication problem we are trying to solve
+09:17 < wsa> is it possible to verify that the PHY actually uses the "delay mode"?
+09:17 < horms> So I can probably say "it doesn't seem to make things worse"
+09:17 < horms> But I can't say "it addresses the issue rasied by the BSP team"
+09:18 < geertu> If you have a fast scope (unikely), you might notice the impact of configuring delay mode on the PHY..
+09:18 < horms> geertu: i do not
+09:18 < horms> wsa: maybe, I can look into that
+09:20 < wsa> At least, that would be okay with me. If the SoC has broken "delay mode" but the PHY has a working one, and we can prove that it is active, I'd think this is what we can do for now without super-fancy test hardware
+09:20 < horms> Undersood. Let me a) think about if I agree and b) do some testing and see what data I can collect
+09:21 < horms> In general I think we should try to move ourselves into a better position to decide
+09:21 < horms> I'll see about making that so
+09:21 < horms> Thanks for your advice
+09:21 < wsa> Thanks, Simon!
+09:22 < wsa> So, neg is still not here, which means I ran out of questions
+09:22 < horms> I'll drop off now, sorry that I can't stay for the entire meeting
+09:22 < wsa> have a nice day!
+09:22 -!- horms [~horms@ip4dab7138.direct-adsl.nl] has quit Quit: Leaving
+09:22 < wsa> are there more questions from your side?
+09:24 < wsa> well then
+09:24 < wsa> geertu: do you want to start now or at 09:30?
+09:25 < geertu> wsa: I prefer at 09:30, for the least amount of surprise
