RAVB doesn't have gPTP but can use the TSN gPTP. We need to find a way how to enable this in the RAVB driver +09:05 < wsa> Wolfram +09:05 < wsa> : had a slowdown of work because of a quarantine in his family. He was not infected, though, and everyone is healthy again. +09:06 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has quit Remote host closed the connection +09:07 < wsa> shimoday: so, you managed to speed up UFS from 300kb/s to 300mb/s? Cool, what was the culprit? +09:07 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has joined #periperi +09:08 < wsa> uli: within the TPU mails, Uwe also mentioned something about a calculation with a double division leading to imprecise values. Did you have a look at that as well? +09:08 < uli> not in detail yet +09:08 < marex> geertu: wsa: is GPU core or IO ? :) +09:08 < shimoday> wsa: there are two things, 1) mismatch UFS mode between host controller and device (called SERIES), 2) host controller doesn't seem to support hibernate mode. +09:08 < geertu> marex: MM? +09:09 < wsa> shimoday: also, with "board assignments", does it mean that Spider boards might be available for EuroPERI? +09:09 < shimoday> I'm asking HW team about hibernate mode. +09:09 < pinchartl> marex: you're welcome in MM :-) +09:09 < wsa> marex: GPU is MM? +09:09 < marex> ugh +09:10 < pinchartl> you seem thrilled by the idea of working with MM people :-D +09:10 < wsa> uli: do you have time to check his other comments as well? I agree with your reasoning for the small values, we just have to see what is consistent in the PWM subsystem +09:10 < shimoday> wsa: My plan was 2 boards to EuroPERI, but other team also wants the board, so I have to discuss the assignment with my boss +09:10 < wsa> if there is a consistency in the PWM subsystem +09:11 < neg> marex: We have tea and cookies +09:11 < shimoday> I hope I could ship a board to EuroPERI at least... +09:11 < uli> wsa: i'm inclined to agree with uwe's comments that it might not be a good idea to change the behavior of an existing driver +09:11 < uli> even if the other drivers behave differently +09:12 < wsa> uli: ok, but then it would maybe be good to add comments= +09:12 < wsa> ? +09:12 < uli> might be +09:13 < wsa> shimoday: well, one board is better than zero, of course :) +09:13 < shimoday> wsa: yes :) +09:14 < geertu> And V4H is at zero, currently? +09:14 < wsa> shimoday: about I2C in U-Boot von V3[HMU]: is it only adding the platforms or is there something wrong which works on other Gen3? +09:15 < wsa> moriperi: can you reveal something about this "Renesas Linux" here now or do we have to wait a little more? +09:16 < moriperi> I'm preparing about it. I hope +1 month I can show you +09:16 < wsa> moriperi: ok, thanks +09:17 < wsa> uli: with the review-tag for v4, it looks good that the CAN series will now be accepted. Very good +09:18 < shimoday> wsa: I realized BSP tead shared the patches today :) I checked them and then add i2c nodes and config "CONFIG_SYS_I2C_RCAR_I2C" only. +09:18 < shimoday> so, it seems easy to upport, IIUC. +09:19 < wsa> shimoday: good. +09:19 < shimoday> s/tead/team/ +09:20 < shimoday> geertu: yes, V3H is at zero, currently. (however, BSP team seems to have a few boards though..) +09:20 < wsa> we have this patch, though, for V3U, don't know if this also needs to be addressed for U-Boot +09:20 < wsa> 9c975c432bc0 ("i2c: rcar: protect against supurious interrupts on V3U") +09:20 < shimoday> s/V3H/V4H/ +09:21 < shimoday> I heard a V4H board for our team is available in April. +09:22 < pinchartl> shimoday: any info about availability of V4H documentation ? +09:22 < wsa> dunno if the spuriuos bits also affect the U-Boot handler but I though I mention it +09:22 < wsa> so, this was it from my side, is there anything from your side? +09:23 < marex> wsa: u-boot doesn't use interrupts, mind you +09:23 < shimoday> pinchartl: I asked in-charge person about V4H documentation, and then they are preparing now. For now, they only prepared a document under NDA of IMP. +09:24 < wsa> marex: yeah, I know, but a reason for the interrupts might be flaky status bits +09:24 < pinchartl> what's IMP ? +09:24 < shimoday> But, we don't have such NDA with Jinzai solution... +09:24 < marex> wsa: right +09:25 < shimoday> Image Processing Unit +09:25 < pinchartl> ah yes that one +09:25 < pinchartl> we would love to have documentation about all that, and upstream drivers :-) +09:27 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has quit Remote host closed the connection +09:27 < geertu> Renesas Upstream First! +09:27 -!- damm [~damm@g1-27-253-251-139.bmobile.ne.jp] has joined #periperi +09:27 < marex> pinchartl: I can get powervr firmware blob sources while at it ? +09:27 < neg> There was a guy in #renesas-soc the other day talking abut the ISP software running on one of the Cortex-A53 (on rz/v2m) is that the IMP? +09:27 < shimoday> pinchartl: yes :) However, Renesas other team doesn't seem to have such a plan... I'm not sure though... +09:28 < pinchartl> marex: if it was just up to me, I'd give you the GPU RTL +09:29 < geertu> neg: "a guy" == Phil Edworthy +09:29 < geertu> ISP != IMP, AFAIK +09:29 < pinchartl> geertu: I don' mind getting both :-) +09:30 < wsa> ok, I guess this is it for the IO meeting +09:30 < pinchartl> shimoday: I know. I wasn't seriously hoping it would happen any time soon. it's a bit of a shame though, there's an increasing interest for open-source drivers for image-processing IP cores. other vendors (such as NXP with their ISP and dewarp engine) are moving in that direction, and I think it would be beneficial for Renesas to do so too. but what do I know :-) +09:30 < neg> geertu: Ahh thanks. He had left the channel before I had the change to ask him about it, and if I could have the code :-) +09:30 < wsa> let's see if we can get the switch from MM to core now ;) +09:30 < wsa> geertu: enjoy! +09:30 < geertu> wsa: Thx! |
