toma: I'm writing support for autofocus firmware for ov5640, and it looks like userspace programs that query for autofocus support end up triggering autofocus. I want to avoid this. How is QUERYCTRL implemented? It presumably uses v4l2_ctrl_ops but how does it use that without the driver triggering the setting of a value?
<br> Found it: v4l2_ctrl_new_std
hverkuil: <u>neg</u>: do you plan to post an update to rcar-isp as well? It looked fine to me, except for the small items I mentioned in my review.
<br> I can combine it with the rcar-vin series.
***: toma has quit IRC (Quit: Page closed)
neg: <u>hverkuil</u>: I do, I was hoping to do so today but looks like I will need to push it to tomorrow, is that OK for you? If net let me know and I will make it happen today
mort_: https://p.mort.coffee/slE Does anyone have an idea what could cause that VIDOIC_STREAMON to error with -32?
<br> that's the broken pipe errno

hverkuil: <u>neg</u>: tomorrow is fine, thank you.
neg: <u>hverkuil</u>: thanks
hverkuil: <u>neg</u>: I noticed that there are also rcar-csi patches for the r8a779a0 that haven't been merged yet ( sailus: what's the status of those). I think it is OK if the rcar-vin series goes in before the rcar-csi, but please confirm that.
neg: <u>hverkuil</u>: They can go in in any order (the rcar-vin, rcar-csi2 and rcar-isp) but all three are needed to enable capture on r8a779a0
hverkuil: I thought so, thanks for confirming.
mort_: <u>error</u>: https://p.mort.coffee/9LJ; topology: https://p.mort.coffee/1D8; topology graph: https://p.mort.coffee/fND.png
<br> https://p.mort.coffee/6fm is the output of v4l2-compliance
hverkuil: <u>mort_</u>: the first two links (9LJ, 1D8) do not work.
<br> EPIPE is typically used if the configured pipeline is invalid (inconsistent formats between the various components).
***: sailus has quit IRC (Quit: leaving)
mort_: the first two links as in the link from the ov5645 to csiphy1 and from csiphy1 to csid1?
hverkuil: yes, all the way to msm_vfe0_pix.
<br> When you call STREAMON the pipeline is validated, and if invalid EPIPE is returned.
mort_: oh, lol, I read "the first two links" as in the first two links between nodes in the graph, I now see that you meant the URLs xP
hverkuil: Yes, URLs :-)
mort_: sorry, they work, but I separated my links with semicolons, make sure those semicolons didn't end up in the URL
<br> so https://p.mort.coffee/1D8 and https://p.mort.coffee/9LJ
<br> is there a way to get video4linux to say why the configured pipeline is invalid?
hverkuil: not that I know of. But it would be nice if media-ctl could do that.
<br> <u>mort_</u>: it's odd that I see no fmt info for msm_csiphy1, msm_csid1 and msm_ispif1. Try setting formats for those entities.
***: sailus has joined #linux-media
mort_: <u>hverkuil</u>: that's curious yeah, I seem to be setting the format in the media-ctl command: https://p.mort.coffee/oil

jmondi: <u>hverkuil</u>: Hello Hans, how are you doing ?
hverkuil: Good, thank you. You as well, I hope?
jmondi: I would say so, yes :)
<br> just a gentle ping from my side for: " media: Introduce post_register() subdev operation"
hverkuil: <u>jmondi</u>: that's odd, it doesn't appear to be in patchwork.
<br> Am I blind?
jmondi: really ?
hverkuil: Can you double check, and if it is missing, repost? patchwork is my memory, if it isn't there, it doesn't exist :-)
jmondi: <u>hverkuil</u>: https://patchwork.linuxtv.org/project/linux-media/list/?series=
<br> found it :)
<br> searching by subject didn't work for me either
<br> ahem
<br> https://patchwork.linuxtv.org/project/linux-media/list/?series=5847
hverkuil: Weird, I'm apparently blind.
<br> Delegated to me.
<br> Now I see it in my todo list.
jmondi: :)
<br> <u>hverkuil</u>: let me know if a resend is required! thanks for now and have a good night!

KitsuWhooa: The latest 5.14 rc2 kernel is detecting my rtl2832u stick as having an MXL5005S tuner, when it has an r820t. Is this a known issue or should I dig into it and bisect it?
