He enabled +09:04 < wsa_> SATA on H3-ES2.0 and sent V2 of IP core switcher patches. And answered requests +09:04 < wsa_> and questions, both internally and externally. +09:04 < wsa_> Shimoda-san worked on USB PHY patches for Gen3 and discussed them. +09:04 < wsa_> B) +09:04 < wsa_> Wolfram wants to finish add. tasks and keep on working on QEMU. R-Car I2C recovery +09:04 < wsa_> gets a V2 and IIC freq calculation patches shall be merged. Also, SDHI topics +09:04 < wsa_> need some love, too. +09:04 < wsa_> Shimoda-san wants to continue on the USB PHY issue as well as investigate a USB3.0 role swap issue. +09:04 < wsa_> Also, he wants to review RZ/A1 patches and get into QEMU & USB as well. +09:04 < wsa_> Simon wants to continue on hacking HS400 and to fix the "no-link" problem on all boards +09:04 < wsa_> C) +09:04 < wsa_> Niklas still misses hardware to test reading thermal calibration from fused registers. +09:04 < wsa_> Simon needs to mine the BSP for more ideas about HS400. +09:05 < wsa_> jmondi: I hope you had no injuries? +09:06 < wsa_> Are there any questions about this? Or about the add. tasks? +09:07 < wsa_> I sent around add. tasks drafts yesterday, except for Simon which I will do today +09:07 < wsa_> sorry for the delay, simon +09:07 < horms> no problem +09:08 < wsa_> so, about one question I have: +09:08 < wsa_> I don't have ULCB schematics. Does someone have? I'd be interested if the IIC_DVFS bus is exposed there somewhere? +09:08 < horms> maybe, i can check +09:09 < wsa_> I don't want to apply the new freq calculation there without testing +09:09 < geertu> wsa_: yes, we have. They are public (check elinux wiki) +09:09 < wsa_> nice +09:10 < wsa_> well, i need to register with renesas :) +09:11 < geertu> wsa_: And after that, you can win e.g. blinkenlight beer coasters ;) +09:11 < wsa_> woot! +09:11 < wsa_> and i have another question: +09:12 < wsa_> we use GPIOs with SDHI for card_detect and write_protect instead of the internal mechanisms. +09:13 < wsa_> does somebody know why? At least on Gen3, the internal mechanisms seem to work fine +09:13 < wsa_> (maybe a tad slower, but still fine) +09:13 < wsa_> was there an old SoC which had problems with that? +09:14 < wsa_> I seem to recall something like that but can't really remember... +09:14 < Marex> wsa_: or maybe a pinmux flexibility issue ? +09:14 < morimoto> I think Magnus knows it +09:14 < morimoto> It was his idea +09:15 < wsa_> OK, I will check with him +09:15 < wsa_> thanks morimoto-san! +09:16 < horms> maybe good to document the answer +09:16 < wsa_> So, this was it already from my side... +09:16 < wsa_> horms: in deed +09:16 < wsa_> shimoda: morimoto: anything else from your side? Are you / Is Renesas happy? :) +09:17 < geertu> wsa_: Using a GPIO has the advantage that the SD card controller can be put to sleep, while CD IRQ/wakeup is handled by GPIO +09:17 < shimoda> i have a problem about hscif and investigate an issue. +09:17 < geertu> Again, software policy vs. hardware desc. +09:18 < wsa_> geertu: yes, that makes sense +09:18 < shimoda> If we send a large data with DMAC, sometimes warning happens from rcar-dmac. but, we cannot reproduce minicom yet. (We use a windows tool "teraterm") +09:19 < shimoda> ("we" mean I and jinso) +09:19 < shimoda> so, we continue to investigate how to reproduce the issue by using minicom somehow +09:19 < wsa_> I see +09:20 < wsa_> Good luck with that! +09:20 < wsa_> minicom --teramode /dev/ttyS0 +09:20 < wsa_> at what speed? +09:20 < wsa_> maybe we can try, too... +09:21 < shimoda> about 1Mbps +09:21 < geertu> "about"? +09:21 < shimoda> with transfer delay per a line +09:21 < geertu> 921600 bps? +09:21 < shimoda> 921600bps +09:21 < shimoda> yes +09:22 < shimoda> if we add 100ms delay per a line, the issue happens easily. the datafile is random and 1Mbytes. +09:23 < wsa_> but only with teraterm? +09:23 < shimoda> minicom also has delayed transfer per a line. +09:23 < shimoda> wsa_: yes +09:25 < wsa_> I'll play around and let you know if I see a warning... +09:25 < wsa_> So, maybe one closing word about the FOSDEM meeting +09:26 < wsa_> with so many people not being there (sadly missed!), I assume the IO meeting will not need much time +09:26 < horms> oh, who will be there? +09:26 < wsa_> But I see some kind of virtualization BOF coming... +09:27 < morimoto> horms: All JaPERIese doesn't go FOSDEM +09:27 < horms> ack +09:27 < wsa_> and ulrich is not coming AFAIK +09:27 < geertu> morimoto: And the SwePERIese? +09:27 < morimoto> geertu: MagPeri ? +09:28 < geertu> morimoto: DamPeri +09:28 < morimoto> He is counted as JaPERIese +09:28 < wsa_> NiklaPERI is coming, though +09:29 < wsa_> So, I think we should have a regular IRC meeting on 25th +09:30 < geertu> Soudns fine to me. +09:30 < wsa_> and in Brussels do some hands-on stuff +09:30 < wsa_> and with that, I think we are done for today +09:31 < pinchartl> wsa_: we'll be busy with the multimedia code camp on the 25th though +09:31 < pinchartl> is there a need for a regular IRC meeting given that there will be an I/O face to face meeting the next day ? +09:32 < wsa_> not the next day +09:32 < wsa_> 8 days later +09:33 < wsa_> i thought your code camp starts on 29th? +09:33 < pinchartl> of course, my bad +09:33 < pinchartl> sorry, I got the weeks mixed up +09:34 < wsa_> good +09:34 < geertu> pinchartl: Does AirBnB agree? +09:34 < wsa_> geertu: prepared to catch the mic? +09:36 < geertu> wsa_: Yes, I'm ready to go! +09:36 < geertu> wsa_: Thanks for leading I/O |
