09:56 < wsa_> hey guys!
09:57 < neg> hello
09:57 < horms> hi all
09:58 < jmondi> Hi there

10:00 < uli___> hi
10:00 -!- morimoto [~user@relprex1.renesas.com] has joined #periperi-io
10:00 < wsa_> hi uli, morimoto-san!
10:00 < morimoto> Hi
10:00 -!- Irssi: #periperi-io: Total of 7 nicks [0 ops, 0 halfops, 0 voices, 7 normal]
10:02 < wsa_> so, nice to have you here, let's start
10:02 < wsa_> i forgot to call for ABC answers, so let's do some informal update report here
10:03 < wsa_> like I worked on additional contracts mainly, and started with the I2C suspend/resume issue
10:04 < wsa_> jmondi: any news?
10:04 < wsa_> (sort -R power again ;)
10:04 < jmondi> wsa_: am I first? :)
10:05 < jmondi> I have closed max9611 driver, no answer from Baylibre on sampling time, no one on iio list commented, so driver will support sysfs attribute access only
10:05 < neg> wsa_: just to be clear, you are asking for ABC updates afther the mail 'IO: call for updates' from 2017-04-07 where this meeting was announced?
10:06 < jmondi> (remember last time we discussed about sampling frequencies for that driver)
10:06 < wsa_> neg: yes
10:06 < jmondi> as reported in the email, B = C = D = NULL
10:06 < wsa_> jmondi: sounds fine to me
10:07 < jmondi> on homework side, I gave a look at genmai schematics to search for un-supported chips, but there's nothing there
10:08 < geertu> jmondi: Is the audio codec connected to SPI supported now?
10:08 < wsa_> jmondi: so, i'll mark the driver as merged. Cool, thanks!
10:08 < jmondi> I also asked Magnus, that last time we spoke said he had some ideas for possible new parts to support, and he pointed me to an led controller, but very low priority it seems
10:08 < geertu> jmondi: When I worked on RSPI, it wasn't, except for a patch in the codec vendor tree, supporting i2c only
10:08 < jmondi> geertu: I've been looking for ADCs/DACs
10:09 -!- dammsan [~dammsan@s214090.ppp.asahi-net.or.jp] has joined #periperi-io
10:09 < wsa_> jmondi: we can discuss the next IO work for you later
10:09 < jmondi> wsa_: yeah! then --eot--
10:09 < geertu> jmondi: Aren't audio codecs DACs? ;-)
10:10 < wsa_> next one, simon, already reported via mail. Thanks Simon!
10:10 < horms> np
10:10 < jmondi> geertu: you have a point, sir :)
10:10 < wsa_> one question about one problem: Priorities for upstreaming
10:11 < wsa_> can you elaborate a little
10:11 < wsa_> ?
10:11 < geertu> jmondi: sound/soc/codecs/wm8978.c exists, i2c only
10:11 < horms> sure
10:11 < horms> I think it should read priorities for upporting
10:11 < horms> I may have typed the wrong word in my email
10:12 < horms> sure
10:12 < wsa_> I see
10:12 < wsa_> Upporting, it is
10:13 < wsa_> did you get the add. task for SDHI?
10:13 < horms> as you may know Kaneko-san and I have been working on analysing the BSP for a while now. And to a lesser extent upporting patches. Meanwhile Morimoto-san has organised an effort to allow better feddback between team leaders and the BSP team on what is desirable to upport. I'm happy for Kaneko-san and I do some backporting based on priorities that come out of the teeam leader/BSP team communication. But I'm unsure what the priorities are.
10:13 < horms> Does that make sense?
10:14 < wsa_> yes
10:14 < horms> wsa_: yes. I have the task. Jinso have signed it. I will once I get access to a printer - I'm still on the road
10:14 < wsa_> good enough
10:14 < geertu> horms: Aren't the [HMLN] characters in the first column the priorities?
10:16 < wsa_> I guess there is some confusion how to merge the work done by Simon and the new list?
10:16 < horms> geertu: yes, indeed they are.
10:17 < horms> I guess my question is the one wsa_ stated
10:17 < horms> My assumption was that the team leaders would be directing upporting activities
10:17 < horms> And I wanted to avoid conflicting with that
10:18 < wsa_> I guess there is still something to be sorted out, but this is not specifically an IO issue.
10:19 < horms> If not, I can just look at the list and choose things based on HMLN :)
10:19 < horms> agreed
10:19 < wsa_> So, while I'd really like to resolve this somewhen, I'd like to go on with the IO stuff...
10:19 < horms> sure
10:19 < horms> no problem
10:20 < wsa_> morimoto: some input from you?
10:20 < morimoto> nothing from me for I/O
10:20 < morimoto> but I can show you my special smile for Wolfram, because you posted I2C suspend/resume support patch
10:20 < morimoto> 	v(^o^)v
10:20 < morimoto>  
10:21 < wsa_> :D
10:21 < wsa_> uli: any news from your side?
10:22 < uli___> haven't done anything for io for a while; i'm waiting for my hscif variable timeout task
10:23 < wsa_> yup, same here
10:24 < wsa_> i'll ping Magnus to see if there are news...
10:24 < wsa_> neg: updates?
10:25 < neg> No public update since last ABC, I did a protype for avb WoL and at least my hack works but still waiting for contract for that, any news if it's delayed?
10:25 < wsa_> nope
10:25 < wsa_> I guess Magnus is just super-busy
10:26 < wsa_> dammsan: right? :)
10:26 < neg> OK np for me, if you want it erlier but delay for some reason I can always try to include it in my base. Let me know what you think is best
10:27 < wsa_> neg: i think it is best to wait a little longer
10:27 < wsa_> keep the 'base' for m/m for now
10:28 < wsa_> neg: if you have a minute after the meeting, can we chat a little?
10:28 < wsa_> geertu: last, but definately not least :)
10:28 < neg> wsa_: sure after meeting is fine
10:29 < geertu> geertu: No changes compared to my email from Apr 6
10:30 < geertu> There seems to be a renewed interest in SPI slave, which is good.
10:30 < geertu> So I'll tackle that soon
10:30 < wsa_> cool!
10:31 < wsa_> looking forward to that
10:31 < wsa_> '/names
10:31 -!- Irssi: #periperi-io: Total of 8 nicks [0 ops, 0 halfops, 0 voices, 8 normal]
10:31 < wsa_> so much for the updates
10:32 < wsa_> now it is time for a big thank you for the "homework"
10:32 < wsa_> i'll include it in the todo list in the next days
10:33 < wsa_> very nice outcome
10:34 < wsa_> so, the only thing I have left is to discuss the next work for jacopo
10:34 < wsa_> but no need for everyone to be present for that
10:34 < wsa_> so, if you have questions comments or so, this is the time now...
10:35 < horms> none at this time
10:35 < neg> I'm happy thanks all
10:36 < wsa_> good then
10:36 < wsa_> then this was the official part
10:36 < wsa_> thanks guys
10:37 < wsa_> jmondi: what boards do you have currently?
10:37 < morimoto> bye-bye
10:38 < jmondi> wsa_: Salvator-X M3, a Genmai and a GR-Peach
10:39 < wsa_> GR-Peach? which SoC is that?
10:40 < geertu> RZ/A1
10:40 < jmondi> RZ A1H
10:40 < wsa_> i see
10:41 < jmondi> this little tiny useless board here https://developer.mbed.org/platforms/Renesas-GR-PEACH/
10:41 < wsa_> useless? :)
10:41 < jmondi> eh
10:41 < jmondi> it comes with on-board sdram only
10:42 < jmondi> it can run a xip kernel from Renesas US BSP
10:42 < jmondi> not tried mainline yet
10:42 < jmondi> it is designed to be used as an mbed platform
10:42 < jmondi> so, yes, a bit useless
10:42 < jmondi> :)
10:43 < wsa_> hehe
10:43 < geertu> s/on-board/on-SoC/
10:44 < jmondi> geertu: correct
10:45 < wsa_> so, I just found out the task I had in mind was for H3. M3-W is not enabled for that yet.
10:45 < wsa_> so, i need to rethink and just write you a mail.
10:46 < jmondi> wsa_: we're going to meet in Japan in ~month, and I'm busy with multimedia, so if I need some particular board, I can collect it there
10:47 < wsa_> I'd think it would be nice if you have a Gen2 board as well (Lager or Koelsch)
10:47 < geertu> jmondi: Unfortunately an H3 has to be shipped officially
10:47 < wsa_> but I don't know the availability of those
10:47 < jmondi> geertu: I heard about that, in fact...
10:47 < geertu> wsa_: digi-key has porters ;-)
10:48 < jmondi> wsa_: I have access to an ALT board from Magnus farm
10:48 < wsa_> last resort :D
10:48 < wsa_> morimoto: do you think it is possible to provide jacopo with a Lager or Koelsch?
10:49 < wsa_> jmondi: so, you are currently busy with m/m anyhow and not exactly bored?
10:49 < jmondi> wsa_: not exactly, no
10:50 < jmondi> I have my hands full with a "background" multimedia task
10:50 < jmondi> that has been brought foreground until the end of May
10:51 < wsa_> full-time until end of may?
10:51 < wsa_> or due-date is end of may?
10:51 < jmondi> due date is end of may
10:51 < wsa_> i see
10:51 < jmondi> and it can be made full time and postpone IO work to June
10:52 < jmondi> I will have 2 weeks for IO if I'm not wrong
10:52 < jmondi> not that much, but I hope it can be extended later ;)
10:53 < wsa_> we'll see
10:53 < jmondi> wsa_: what did you have in mind?
10:53 < wsa_> ok, so you have stuff to do now which gives me some time to reschedule
10:54 < wsa_> we got some failure reports. And I wanted you to check a few of those
10:55 < wsa_> probably low-hanging fruits once the problem is analyzed
10:55 < wsa_> but exactly that needs to be done :)
10:55 < wsa_> like 'aplay' crashes when the i2c driver is rebound
10:55 < wsa_> but we don't have sound yet on M3
10:56 < geertu> wsa_: Isn't that fixable by adding a few devices to the DTS?
10:56 < wsa_> might be
10:56 < geertu> You may want to check with Simon, as he was going to do that, IIRC (cfr. meeting before FOSDEM)
10:56 < wsa_> but that i need to check before assigning the task
10:57 < wsa_> because the task is not "enable sound on M3" ;)
10:57 < jmondi> wsa_: are those "The failure summary report of ..." ?
10:58 < jmondi> from jinso, usually..
10:58 < wsa_> yes
10:59 < wsa_> but the newer ones are not sent to the list anymore
10:59 < wsa_> and careful, some of the issues are moot, IMO
11:00 < jmondi> I see, I read a bit of discussions on reported multimedia issues, and yes, they need double-checks :)
11:00 < wsa_> they do
11:00 < jmondi> so Wolfram, would you like to have some more time to think on this?
11:00 < wsa_> but one or two are worth being researched IMO
11:00 < wsa_> yes
11:01 < jmondi> as I've said, I'm not in a rush and not getting bored here
11:01 < wsa_> that's perfect
11:01 < wsa_> so, I'll come back to you when I sorted out things
11:01 < jmondi> sure! thanks for now then
11:01 < wsa_> and I'll see if we can get you a Gen2 board
11:01 < jmondi> that would be lovely
11:02 < jmondi> I still have some space on my desk :)
11:04 < wsa_> hehe
11:05 < wsa_> thanks, jacopo. i think we are done for now
11:07 < jmondi> thank you
11:07 < jmondi> I'll wait from updates then
11:08 < jmondi> bye bye
11:10 < wsa_> bye
