+<geertu> kbingham: Wake up!
+<uli___> kbingham[m]: ^
+<geertu> MultiMedia is in (cryogenic?) stasis...  [17:20]
+<neg> Maybe he is on some odd none EU timezone ;-) In the meantime shall we do
+      status reports individually in name order (jmondi, kbingham, morimoto,
+      neg, uli___ )?
+<jmondi> neg: fine with me  [17:21]
+<jmondi> even if I guess, the important part is collecting it, more than
+	 re-writing here what we reported by email
+<jmondi> I can start though
+<jmondi> - DRM bridge format support [PATCH 0/8] drm: bridge: Add support for
+	 static image formats HAve to really look into comments, unfortunately
+	 seems like we opened pandora's box of bridges lifetime management.
+								        [17:22]
+<jmondi> - MT9T111 media: i2c: mt9t112: Add OF tree support[3~
+<jmondi> - Gen-3 VIN parallel support on D3  [17:23]
+<jmondi> capture now sort-of-wroking on v4.16 -> v4.17 has severe issues with
+	 memory corruption while capturing
+<jmondi> Until next time)
+<jmondi> - Complete VIN parallel support (due date 5/M)  [17:24]
+<jmondi> - Re-tackle the bridges issues
+<jmondi> - Have MT9T111 capture working on peach, so I can integrate it on
+	 Armadillo
+<jmondi> - soc_camera removal
+<jmondi> Problems I have now)
+<jmondi> - Capturing on v4.17 is very fragile
+<jmondi> --eot--
+<neg> soc_camera removal \o/  [17:25]
+<jmondi> neg: slow down, it's the third time in a row that it gets post-poned
+	 to "until next time"  [17:26]
+<jmondi> is very low priority
+<neg> morimoto: do you have status update for MM?  [17:28]
+<morimoto> OK
+<morimoto> A) What have I done since last time
+<marex-cloud> geertu: not bootargs to your scripts, but mtdparts to your
+	      bootargs, which you are clearly passing already ... btw we can
+	      continue the discussion in #perimtd if you want ( dammsan too )
+<morimoto> IRQ
+<morimoto> OK, continue  [17:29]
+<morimoto> - Enjoyed GW !
+<morimoto> - DMAC driver error handling fixup
+<morimoto> # Current DMAC driver is sharing error IRQ for all channels,
+<morimoto> # but, it will be issue if we uses Virtual Machine, Multi OS, etc.
+<morimoto> # We can handle it on each channel's IRQ handler
+<morimoto> - Considering new PeriPeri tool (= periupport + peripelist =
+	   "periject")
+<morimoto> - Posted ALSA SoC cleanup patches final step
+<morimoto> B) What I plan to do till next time
+<morimoto> - Consider periject design
+<morimoto> C) Problems I have currently
+<morimoto> - I want to know each member's opinion about periject.
+<morimoto> but on-email is very OK
+<morimoto> -- EOF --
+<shimoda> sorry, i have to go home. bye!  [17:30]
+*** shimoda (~shimoda@relprex3.renesas.com) has quit: Quit: WeeChat 0.4.2
+<morimoto> any question ?
+<morimoto> if no, next is neg
+<neg> So far I like the name periject :-)
+<neg> thanks
+<neg> 	rcar_csi2_write(priv, PHYCNT_REG, PHYCNT_RSTZ);
+<neg> 	rcar_csi2_write(priv, PHTC_REG, PHTC_TESTCLR);  [17:31]
+<neg> wops
+<neg> A)
+<neg> - Posted and got merged second batch of VIN enhancement patches.
+<neg> - VIN M3-N done.
+<neg> - Rework CSI-2 based on datasheet v1.0, new patches pending.
+<neg> - Investigated ADV748x behavior of AFE pixel clock.
+<neg> B)
+<neg> - More CSI-2 work
+<neg> - Post next batch of VIN patches that piled up prior to Gen3 merger.
+								        [17:32]
+<neg> - Post fix for ADV748x
+<neg> - Post prototype for v4l2-subdev video standard control
+<neg> C)
+* geertu joined #perimtd
+<neg> - CSI-2 rework will maybe make it too late for v4.18 :-(
+<neg> -- eot --
+<neg> if no questions please go a head uli___  [17:33]
+<uli___> A)
+<uli___> MM: wikified the instructions for running the IGT test suite
+<uli___> (https://elinux.org/R-Car/Tests:igt)
+<uli___> MM: rebasing IGT DU fixes, WIP
+<uli___> MM: adding DU support to D3, WIP
+<uli___> B)  [17:34]
+<uli___> MM: finish DU on D3
+<uli___> MM: send a new IGT DU fix series
+<uli___> C)
+<uli___> none
+<uli___> correction: C) copy-and-paste doesn't work very well in xfce terminal
+<uli___> that's it  [17:35]
+<neg> thanks, out of curiosity is there any DU work for M3-N in the pipeline?
+<uli___> not from me  [17:36]
+<jmondi> neg: I think Kieran was about to work on that
+<neg> jmondi: ok thanks I'm just curious  [17:37]
+<neg> anything else we need to discuss for MM, I had counted on kbingham to
+      handle this so I have nothng prepared but have not read all status mails
+      in detail if there where any open questions
+<morimoto> I have nothing  [17:39]
+<jmondi> neg: I only have the issues with v4.17 capture not working
+<uli___> none here
+<geertu> neg: [PATCH v2 00/11] r8a77965: M3-N DU Enablement
+<jmondi> but actually v4.16 behaves the same, I'm finding out as we speak
+<neg> geertu: thanks how could I miss that, I need a beter interface to gmane
+      archive I keep missing patches  [17:40]
+<uli___> jmondi: how exactly does it not work?  [17:41]
+<jmondi> uli___: by 'randomly' hangs the CPU while capture operations is
+	 starting  [17:42]
+<jmondi> uli___: yesterday Niklas suggested that power cyclcing the board
+	 would help as it may be some v4.17 memory corruption issue
+								        [17:43]
+<kbingham> ??
+<kbingham> Have I just walked into a meeting that I didn't know was happening
+	   ?
+<jmondi> uli___: and it actually did, this morning I re-based on v4.16, first
+	 boot was ok, but now I still need to power cycle to have capture
+	 working
+<neg> jmondi: have you nailed it down to know if s_stream() have been called
+      or if it's the set_fmt() that is the last v4l2 callback?  [17:44]
+<morimoto> kbingham: meeting is almost ending stage now :)
+<kbingham> morimoto: Oh my ... I'm sorry ! I thought meetings were thursdays!
+<jmondi> neg: with strace I see g_fmt being called and that's it
+<neg> kbingham: :-)
+<jmondi> but I would not trust strace too much to debug these kind of issues
+<morimoto> kbingham: :)  [17:45]
+<neg> jmondi: i think some trace printouts in rcar-vin/rcar-dma.c would be
+      usefull to know if it's s_stream() or something else cousing the lockup
+								        [17:46]
+<jmondi> neg: you see, it is freaking 'random'.. I've been capturing images
+	 for a good 2 hours, rebooted the board, no kernel updates, now it
+	 hangs
+<kbingham> neg: M3-N DU should be in renesas-drivers already.  [17:47]
+<jmondi> neg: I was not correct, I changed the pixel clock polarity between 2
+	 reboots, I hardly think that can hang the CPU  [17:48]
+<neg> jmondi: ouch that is bad, I had the impression it always failed on the
+      second capture attempt by bad
+<jmondi> btw, let's tak it offline, I have nothing else for the meeting
+<jmondi> neg: no, I made several captures in a row, until I have rebooted the
+	 board  [17:49]
+<neg> Yes lets keep talking about that later to not hold everyone up :-)
+<kbingham> So Shall I post my ABC ... and then that covers the status' :D
+<neg> kbingham: please do so if you have it handy :-)  [17:50]
+<kbingham> Thursday 10th May
+<kbingham>   
+<kbingham> A) What I have done since last time
+<kbingham>  - M3-N DU Enablement
+<kbingham>  - Got JTAG working with OpenOCD and Salvator-XS
+<kbingham>  - TLB-Opimise v7,8,9
+<kbingham>  - DU/Interlaced v3, v4
+<kbingham> B) What I will do next
+<kbingham>  - DMA Virtualisation
+<kbingham> C) Any issues I have currently
+<kbingham>  - None
+<kbingham> Ahem ... ignore the first line ...  [17:51]
+<kbingham> I'll post that to the ML as a late addition
+<neg> thanks, I think the last item on the agenda is to pick who will record
+      the MM log into the format pinchartl usually do and make sure it's sent
+      out and recorded in the wiki and what else normaly happens with it
+								        [17:52]
+<kbingham> neg: I think that was supposed to be me - but I'm not certain I
+	   have all the scrollback ...  [17:53]
+*** horms (~horms@a80-127-179-77.adsl.xs4all.nl) has quit: Ping timeout: 264
+    seconds
+<morimoto> neg: I can put it to wiki  [17:54]
+<morimoto> kbingham: can you create it by using wiki ?
+<kbingham> morimoto: Sure :)
+<neg> kbingham: I can email you the full scrollback if you need it  [17:55]
+<kbingham> neg: morimoto: - An e-mail is probably easier thanks
