09:04 < wsa> okay, then let's start the IO meeting
09:04 < wsa> welcome everyone!
09:04 * jmondi spills some strong coffee to marex
09:04 < jmondi> ahah too much coffee for Marek now
09:04 < jmondi> sorry wsa, go on :)
09:04 < wsa> here are the status updates
09:05 < wsa> Status updates
09:05 < wsa> ==============
09:05 < wsa> A - what have I done since last time
09:05 < wsa> ------------------------------------
09:05 < wsa> Geert
09:05 < wsa> : fixed Ethernet after kexec/rebind and added missing Ethernet PHY resets on all boards, looked up when alt/gose ee100000.mmc broke
09:05 < wsa> Niklas
09:05 < wsa> : sent next version of reading calibration from fuses for thermal
09:05 < wsa> Shimoda-san
09:05 < wsa> : fixed freeing wrong tx descriptor for SH ethernet, fixed suspend/resume for CAN, sent patch to add c_sync parameter to the USB audio gadget, continued to improve R-Car S4 Ethernet driver
09:05 < wsa> Ulrich
09:05 < wsa> : sent series to integrate V3U registers into the CAN driver and enable CAN on V3U
09:05 < wsa> Wolfram
09:05 < wsa> : tested Ulrich's SCIF patch for SysRq, created test case and implemented and sent out proper bugfix for data corruption issue with RPC-IF, enabled RPC-IF on V3U, sent out new version of the GPIO logic analyzer, sent out RFC for making SDnH a seperate clock, sent series to also abort tuning with CMD12 for SD, found two alternatives to make SanDisk cards work better with SDHI,
09:05 < wsa> reviewed RPC-IF enablement for G2L, discussed handling of undocumented bits for RPC-IF, upported minor patches for TPU, upported patch to avoid a theoretical race for I2C, helped investigating resume issue on Ebisu, sent a treewide cleanup series for getting .driver_data
09:05 < wsa> B - what I want to do until next time
09:05 < wsa> -------------------------------------
09:05 < wsa> Shimoda-san
09:05 < wsa> : wants to continue to improve R-Car S4 Ethernet driver, and to continue to make more eLinux articles
09:05 < wsa> Ulrich
09:05 < wsa> : wants to address issues in the V3U CAN series and send new version
09:05 < wsa> Wolfram
09:05 < wsa> : wants to handle bus-recovery consistently in the I2C subsystem, handle responses to patches for SDnH separation, send proper patch to avoid usage of undocumented bits for RPC-IF, more investigation for resume issue on Ebisu, find best solution to handle SanDisk cards with SDHI, pick up TPU patches again which need refactoring, send hopefully final version of the GPIO logic analyzer
09:05 < geertu> moriperi: Seems like people complained about it on lkml in 2020, which migth have hit Ubuntu now
09:05 < wsa> C - problems I currently have
09:05 < wsa> -----------------------------
09:05 < wsa> Niklas
09:05 < wsa> : still wonders how to upstream the patches when there seems now HW for it
09:05 < wsa> and brand-new:
09:05 < wsa> Marek
09:05 < wsa> : tries to wake up
09:05 < wsa> :D
09:06 < wsa> geertu: when did gose/alt break? I can't recall a mail about that, but it is interesting, of course
09:07 < geertu> wsa: https://lore.kernel.org/all/CAMuHMdUuqQe6cM-Zt1GWq6xgydv1po8FOOW9qWe+5hK=ZRqE+w@mail.gmail.com/
09:07 < wsa> shimoday: I think the CAN patches from uli are already good enough for testing. geertu had some comments but they don't affect functionality. IIRC Goda-san wanted to test the patches on V3U?
09:07 < moriperi> geertu: thanks. do you know the url or something what I can check ?
09:07 < geertu> - gose worked in v4.15, and is broken since at least v4.17,
09:07 < geertu> - alt worked in v5.1-rc6, and is broken now.
09:08 < geertu> moriperi: https://lore.kernel.org/linux-nfs/635679406.70384074.1603272832846.JavaMail.zimbra@dneg.com/
09:08 < geertu> might be a starting point. good luck!
09:08 < wsa> geertu: ah, this mail
09:08 < wsa> geertu: okay, i thought there was a follow-up
09:09 < wsa> I have access to Gose now, too (thanks, Magnus!), so when time permits I can have a look as well
09:09 < geertu> wsa: Yep, after that I tried "[PATCH 0/3] mmc: also abort tuning with CMD12 for SD"
09:09 < geertu> didn't help
09:10 < shimoday> wsa: I think goda-san will not test the can patch on V3U. is it ok for upstream?
09:10 < wsa> geertu: I would have been seriously surprised, if it did :D
09:10 < wsa> so, we got RPC in a much better state since the last meeting
09:11 < wsa> I think it should be actually usable now ;)
09:11 < wsa> neg: about your issue with HW with fuses actually set, did you ask Renesas Europe already?
09:12 < neg> no I have only asked around in Renesas Japan
09:12 < wsa> patersonc[m]: you here?
09:12 < neg> So my question is if we think it's OK to send the next version of the patch on the public ML in hope someone with the fuses set can test it
09:14 < wsa> that would be a customer, or?
09:15 < wsa> new idea: maybe it makes sense to ask Dirk Behme (Bosch) directly if they have the fuses set?
09:15 < wsa> I could do that...
09:15 < neg> Good idea, I will try that
09:16 < wsa> you can do that, too, of course :)
09:16 < geertu> or
09:16 < geertu> Eugeniu Rosca at ADIT?
09:16 < neg> Or if you know him please go a head and do so, likely the success rate is higher then me cold calling him
09:17 < wsa> neg: yes, I know him a little. I will do it
09:17 < neg> Maybe the best way then is to post the patch to the public ML as a RFT and CC Dirk and Eugeniu asking if they have production hardware where the fuses are set?
09:17 < wsa> geertu: yes, another good candidate
09:19 < neg> OK let's start with wsa talking to Dirk and we can take it from there, thanks for the help
09:19 * wsa gets attacked by a puppy
09:19 < wsa> any questions from your side?
09:20 < geertu> wsa: pitbull puppies grow into full-fledged pitbulls?
09:20 < neg> wsa: I will summarise it in a mail to you
09:20 < wsa> neg: thanks
09:21 < wsa> geertu: this one attacks with cuteness
09:22 < patersonc[m]> wsa: MOrnin
09:23 < wsa> Hi patersonc[m]: do you know if any of the Gen3-alike SoCs has the fuses set for the Thermal IP cores?
09:24 < wsa> our development boards don't have it, so we can't test the patches reading the parameters from fuses
09:25 < neg> The test for this is to check if BIT(15) and BIT(14) in the Thermal THSCP is set
09:25 < patersonc[m]> Oh. Why would they disable that?
09:26 < patersonc[m]> wsa: I'm just on the school run atm. Will check when I get home
09:26 < wsa> because they are not final when we get the prototypes AFAIU
09:26 < wsa> patersonc[m]: thanks!
09:27 < wsa> patersonc[m]: can you contact Niklas with your findings? that would be great
09:28 < shimoday> wsa: neg: about the thermal fuse, should I ask BSP team?
09:28 < wsa> shimoday: yes, please
09:28 < neg> shimoday: please do
09:28 < wsa> ah, now I see that shimoday replied to the CAN question
09:29 < wsa> hmm, Uli's patch is too big to upstream it untested, I am afraid :(
09:29 < shimoday> wsa: neg: i got it.
09:29 < neg> shimoday: On internal ML please check '[RFT 0/2] thermal: rcar_gen3_thermal: Read calibration from fuses'
09:30 < shimoday> neg: thank you for the indicate, i'll ask BSP team.
09:31 < wsa> seems we have to check again how to test CAN on V3U ourselves
09:31 < wsa> I guess we really want this patch as it paves the way for S4
09:31 < wsa> which has 16 CAN channels
09:32 < shimoday> wsa: i agree (the patch is too big)
09:32 < wsa> will need to check the schematics
09:34 < wsa> okay, I guess we can move to core then?
09:34 < geertu> wsa: I think so
09:34 < wsa> geertu: here is the mic!
09:34 < wsa> thanks everyone!
