07:53 <Kwiboo> mmind00: Thanks! :-)

08:08 <qschulz> rtp: Kwiboo: ok thanks, i'll just disable video in U-Boot until a client requests it and I'll have to dig into this mess :)

08:24 <rtp> qschulz: fwiw, when I pushed the changes into u-boot, it was working fine. I've used it with grub efi and it was fine. It's when I tried to update to newer kernels and uboot (in january?) that I got the vopl issue when booting linux reproductibly. didn't try newer kernels/uboot

08:32 <qschulz> rtp: define "working fine", I have two issues. One is that there are artifacts on HDMI right after the U-Boot logo is shown, when the kernel boots up.

08:33 <qschulz> Then for some reason, if I have both DSI and HDMI connected, DSI isn't working until I disconnect HDMI (or reorder probe order of HDMI/DSI in rockchip-drm driver)

08:35 <qschulz> ad 1) but HDMI works in kernel after the artifacts FYI

08:43 <naoki> strange, microSD card detect is not working on mainline. it seems it's working on vendor kernel

08:43 <naoki> oops. CD is not working on ROCK 3A

08:43 <phh> `broken-cd;` ftw

08:48 <naoki> I know workaround

08:48 <naoki> I don't know why it doesn't work on mainline

08:50 <rtp> qschulz: on my pbp, I've only a edp display and I don't remember seeing arctifacts. So can't test HDMI/DSI. my roc-rk3399-pc is not connected to any display.

08:51 <qschulz> rtp: oh, I thought the pbp had an HDMI output but only DP altmode it seems?

08:51 <rtp> yeah, only dp alt mode

08:51 <qschulz> wise, wise :)

08:52 <rtp> I tried different usb c adapters and only the altmode dp worked

09:12 <qschulz> Kwiboo: I tried https://lore.kernel.org/all/20240615170417.3134517-14-jonas@kwiboo.se/ and it indeed fixes the issue with me... but I got a hunch that this wasn't enough... so I swapped the order of HDMI and DSI probing in the rockchip-drm (which is what I needed initially without that patch to make DSI work) and it broke the same way it's currently broken for me

09:12 <qschulz> Kwiboo: looks like HDMI needs to be forced to VOPB maybe?

09:27 <naoki> it seems rock-3a was added in v5.19

09:27 <naoki> should I try v5.19...?

09:33 <mmind00> qschulz: likely ... some people do in their device-specific kernels remove the link between vopl and hdmi ... from the upstream side, vopl is supposed to work with hdmi it just has less resolution available (no 4k I think), so that would need to be solved in the driver

09:34 <qschulz> mmind00: yeah, in a way HDMI does work with both vopl and vopb, it's just that when it uses vopl, it breaks DSI :)

10:12 <naoki> I confirmed that microSD CD is not working on ROCK 3A with v5.19 kernel

10:12 <naoki> it didn't work from the beginning, really?

10:13 <qschulz> naoki: check the CD pin works in GPIO mode with sysfs?

10:13 <qschulz> ah, nvm you said it works in vendor kernel

10:16 <naoki> as far as I can see, dts in vendor kernel doesn't use polling mode...

10:19 <naoki> strange

10:21 <naoki> if microSD is inserted during boot, it's recognized (it's ok, common behavior), and if I remove microSD, kernel detect it "mmc0: card 1234 removed". I think it's strange

10:32 <naoki> mmind00: btw, could you pick this fix? https://patchwork.kernel.org/project/linux-rockchip/patch/20240722095216.1656081-1-naoki@radxa.com/

10:32 <naoki> previous incomplete "fix" was already backported to stable branches...

10:39 <diederik> https://lore.kernel.org/linux-rockchip/20240709105428.1176375-1-i@eh5.me/ also seems like a candidate for 'fixes'?

20:26 <naoki> mmind00: thanks!
