| 00:00.26 | sailus | Do you have a working setup with any kernel at the moment? |
| 00:03.38 | DocScrutinizer05 | no DT support sounds like fun |
| 00:04.21 | DocScrutinizer05 | sailus: well Nokia kernel works just fine ;-) |
| 00:04.41 | DocScrutinizer05 | a tad long in the teeth though |
| 00:05.42 | DocScrutinizer05 | I think freemangordon got it semi-working with a 3.x or 4.x kernel, at times |
| 00:06.43 | DocScrutinizer05 | I dunno if the relevant bit in Nokia kernel (and userland) are FOSS though |
| 00:07.28 | DocScrutinizer05 | bits even |
| 00:07.51 | sailus | They're not. |
| 00:08.30 | sailus | The omap3camd is closed, and it implements the automatic exposure, white balance and focus algorithms. |
| 00:08.34 | DocScrutinizer05 | there's /lib/firmware/et8ek8-0002.bin |
| 00:08.57 | sailus | The APIs it expects are not upstreamed, but one could implement a wrapper to convert the IOCTLs to what's in the mainline kernel. |
| 00:08.59 | DocScrutinizer05 | yeah, thought as much |
| 00:09.16 | sailus | I think it'd be good to get it working on a recent kernel first. |
| 00:09.25 | sailus | Either of the cameras. |
| 00:09.27 | DocScrutinizer05 | yes, for sure |
| 00:09.52 | DocScrutinizer05 | you know if there's any init of the sensor done in mainline? |
| 00:10.13 | DocScrutinizer05 | see my URL wall above |
| 00:10.35 | sailus | There's no DT support for CCP2 in upstream. |
| 00:10.52 | DocScrutinizer05 | then anything beyond is moot to discuss |
| 00:10.55 | sailus | Other than that, the front camera should be supported in upstream with the smiapp driver. |
| 00:11.17 | DocScrutinizer05 | may I query you? |
| 00:12.55 | sailus | What about the screenshots? |
| 00:22.53 | sailus | For what it's worth, I have preliminary patches for CCP2 support: |
| 00:23.01 | sailus | http://git.retiisi.org.uk/?p=~sailus/linux.git;a=shortlog;h=refs/heads/rm696-056-ccp2 |
| 00:23.21 | sailus | (I'm pushing right now so it won't work until after a while.) |
| 00:24.14 | sailus | I didn't upstream those as some of the patches are hacks and they haven't been verified with CCP2 working. |

| 06:12.13 | freemangordon | sailus: There is *some* DT support/setup in Pali's tree, no idea if it is correct, but ooks like. see https://github.com/pali/linux-n900/commit/ec98148da1b1665facb13f49757742952d8eb47d |
| 06:14.54 | freemangordon | that video-bus-switch is a driver from sre, that controls camera switch gpio based on which pad is linked. I verified the clocks and power supplies, all seems fine, smiapp is ok too, according to the logs (it has debug logs enabled) |
| 06:16.35 | freemangordon | but as I told you, CSI1 never gets enabled, so I had to patch that, see https://github.com/pali/linux-n900/blob/v4.6-rc1-n900/drivers/media/platform/omap3isp/ispccp2.c#L840 |
| 06:18.54 | freemangordon | ccp2->phy is always NULL, as there is no PHY for CSI1. No idea if this is the way it should be, however I added a code enabling CSI1 (CONTROL_CSIRXFE) in ccp2_if_configure() |
| 06:21.21 | freemangordon | I also got all the values from ISP_CSI1B register array, while front camera is active in stock kernel and put them back while trying to get some video with mainline (with devmem2), no sucess |
| 06:24.33 | freemangordon | sailus: this is the pipeline I use http://pastebin.com/AtbriatN , I see on obvious mistakes in it |
| 06:26.46 | freemangordon | also, in DTS there vdds_csib-supply was missing, but in the DTS here it is added |
| 06:28.13 | freemangordon | the only suspicious things in the logs is "omap3isp 480bc000.isp: Entity type for entity OMAP3 ISP XXXXX was not initialized!", where XXXXX is CCP2, CSI2a, CCDC... |
| 06:33.01 | freemangordon | sailus: yavta, from the pastebin ^^^ just hangs waiting for a frame, mplayer times out. When I try to stop mplayer or yavta, there are messages like "OMAP3 ISP resizer: module stop timeout." and "CCDC stop timeout!" |
| 06:35.12 | freemangordon | sailus: http://pastebin.com/EZKs6Gst , ISP registers from one of my attempts, CCP2 enable bit is 0, but that's normal as registers are printed just before CCP2 is enabled |

| 07:51.47 | sailus | freemangordon: video-bus-switch sounds like the right thing, I haven't looked at it though. |
| 07:53.44 | bencoh | regarding automatic exposure/wb/focus we have fcam drivers/userland as well |
| 07:54.19 | bencoh | I dunno if it depends on omap3camd in some way |
| 07:54.26 | freemangordon_ | sailus: yeah. https://github.com/pali/linux-n900/blob/v4.6-rc1-n900/drivers/media/platform/video-bus-switch.c |
| 07:55.00 | freemangordon_ | I had to do a couple of fixes though |
| 07:56.00 | freemangordon_ | sailus: however, to my understanding, vbs doesn't look related to the problems I face |
| 07:58.21 | sailus | I think I must have suspended my laptop before the push finished. |
| 07:58.26 | sailus | I'll redo that noe. |
| 07:58.29 | freemangordon_ | :) |
| 08:04.04 | sailus | Hmm. I pushed it to wrong repository. :-P |
| 08:04.31 | sailus | Pushing again now... |
| 08:05.43 | sailus | There it is. |
| 08:06.04 | sailus | freemangordon_: Do you happen to get interrupts from the isp? |
| 08:13.03 | freemangordon_ | sailus: I suspect no (IRQ debug is not enabled in the config) |
| 08:13.45 | freemangordon_ | sailus: "Firefox can't find the server at git.retiisi.org.uk." |

| 10:11.04 | sailus | What's the problem you have? |
| 10:11.34 | sailus | I.e. can you connect to it using telnet on that port, or not, and ipv4 or ipv6? |
| 10:11.45 | sailus | Both should work. |
| 10:16.10 | freemangordon_ | sailus: trying to open "http://git.retiisi.org.uk/?p=~sailus/linux.git;a=shortlog;h=refs/heads/rm696-056-ccp2" in ff results in "Firefox can't find the server at git.retiisi.org.uk.". trying to open "http://retiisi.org.uk/?p=~sailus/linux.git;a=shortlog;h=refs/heads/rm696-056-ccp2" brings me to "http://retiisi.org.uk/~sailus/", unfortunately the page is not in English, so I am not sure what is written there |

| 13:48.00 | freemangordon | sailus: those patches are already in the tree I use |
| 13:50.30 | freemangordon | sailus: https://github.com/pali/linux-n900/commits/v4.6-rc1-n900?page=4 |
| 14:01.08 | freemangordon | feels stupid, interrupts are in /proc, not in /sys/kernel/debug :( |
| 14:06.32 | freemangordon | sailus: "480bd400.mmu, OMAP3 ISP" interrupt count stays at zero |
| 14:15.17 | sailus | Yeah, I think it's the same problem that's been seen before. |
| 14:15.51 | sailus | I can't give other suggestions than to bisect that, or check the hardware configuration at register level with a working setup. :-( |
| 14:16.27 | freemangordon | sailus: which registers I should check? |
| 14:16.43 | freemangordon | only CCP or CCDC etc as well? |
| 14:20.39 | sailus | At least system clock tree configuration and the control block register for the receivers. |
| 14:21.01 | sailus | I think there once was a suspicion that this could have been caused by changes in the clock control. |
| 14:21.26 | sailus | pinchartl might remember. |
| 14:21.54 | sailus | Pali as well. Googling should turn up results. |
| 14:22.45 | freemangordon | sailus: well, I already checked clocks, see http://pastebin.com/dM8Zf60M |
| 14:22.56 | freemangordon | looks ok, ain;t? |
| 14:25.46 | freemangordon | sailus: there *is* a difference in what stock kernel sets in ISP_CSI1B compared with mainline, howecer writing the same values with devmem2 doesn't make a differenece |
| 14:32.04 | sailus | What are the values? |
| 14:33.36 | freemangordon | sailus: http://pastebin.com/fZaJ1uvy |
| 14:34.09 | freemangordon | the major difference I see is in CSI1B_DAT_START/SIZE |
| 14:35.10 | freemangordon | sailus: hmm, isn;t there a typo when getting clock-lane? http://salottisipuli.retiisi.org.uk/cgi-bin/gitweb.cgi?p=~sailus/linux.git;a=commitdiff;h=3710afacd0dfec5504ebfbf5d5850bbb07ee28c6 |
| 14:36.26 | freemangordon | sailus: also, why bus type should be CCP2 but not CSI1? |
| 14:37.28 | freemangordon | afaik cameras on n900 are connected to CSI1b, not CCP |
| 14:44.07 | sailus | freemangordon: I'll have to check that later on, I have a meeting starting soon... |
| 14:45.00 | freemangordon | sailus: ok, in the meanwile I think I am on something |
