00:26 <karlp> is "usbphy" _only_ used for the usb host ports, or also for the otg port? https://elixir.bootlin.com/linux/latest/source/arch/arm/boot/dts/sunxi-h3-h5.dtsi#L255

00:27 <karlp> I've got a board with _only_ the otg port on it, and a baseboard with the ehci/ohci 2/3 ports, and trying to work out where to put the "&usbphy: status="okay"" line, in teh parent, or the docked board file

00:28 <karlp> the usb_otg node seems to refer to usbphy 0?

00:29 <karlp> and if usb_otg is really ehci/ohci 0, then I need to make sure they're enabled too, if I want to use the otg port in host mode?

01:56 <ric96> Does the lichee zero (V3s) support 40pin display in mainline? I'm only looking for fbdev. A quick google revealed some patches but what's the status?

01:56 <ric96> Thanks

01:59 <noblock> H5: I tried lima; it operates properly at 800x600; Higher resolutions failed with the following error: lima 1e80000.gpu: pp error irq state=201 status=40

02:01 <noblock> The issue is the same with the mali blob; at 800x600 no error; At 1024x768: Executor: Mali page fault detected at 0x12815d00 from bus id 8 of type read on Mali_PP_MMU_Broadcast..

02:02 <noblock> An idea why this issue seems to be specific to the H5?

02:07 noblock has quit [Quit: Leaving]

02:20 <smaeul> karlp: usbphy is for all ports, on both musb and ohci/ehci controllers

02:21 <smaeul> musb and ohci0/ehci0 are muxed to the same pins, so if you only need host mode you can avoid the buggy musb

06:38 <quark_> wens: great

06:40 <quark_> Lee is asking about SOB. Is it so if I send other people patches I have to add my own SOB to it?

06:41 f0xx has joined #linux-sunxi

06:41 <wens> always

06:42 <wens> in this case it is a bit more confusing, because since this was your patch to begin with, your SoB is already there

06:43 <wens> in hindsight you probably should've mentioned you picked my github branch in the cover letter, and/or in comments to each patch

06:44 <wens> quark_: anyway, just reply and be truthful about where the patches came from, and why they ended up like that

08:55 <noblock> wens: This issue seems to be H5 specific; and not related to lima itself; This looks like a bus wrapping problem; For instance: glmark2-es2-fb -b build --run-forever --size 1024x512: No error, even at 600MHz (using the r5p0 blob).

08:58 <noblock> With higher resolutions; it fails with Executor: 'Mali page fault detected', followed by 'Mali PP: Hard reset of core Mali_PP0'....

09:47 <jaganteki> Hi, anyone tried opengl, via mali on Mainline?

09:47 mpmc has quit [Ping timeout: 250 seconds]

09:47 <jaganteki> seems it broken since from 4.18 894a677f4b3e6d2ab8d01bb46c1fbd5f92e4591b

09:48 <Net147> jaganteki: I am using successfully on 4.19 but I have fbdev emulation disabled

09:49 <Net147> jaganteki: using GBM instead of fbdev

09:50 <jaganteki> ohh.. I disabled via CONFIG_DRM_FBDEV_EMULATION but seems /dev/fb0 is not detected

09:51 <jaganteki> I'm using libmali with qt

09:51 <Net147> you can do that using GBM

09:54 <jaganteki> is this GBM you tried? https://github.com/ds-hwang/gbm_es2_demo

09:55 <Net147> use the Wayland libmali and run Qt application with QT_QPA_PLATFORM=eglfs QT_QPA_EGLFS_INTEGRATION=eglfs_kms

09:55 <Net147> no need to have wayland running, it is just a library link dependency

09:56 <Net147> I haven't tried that demo

10:11 <jaganteki> Net147, I'm using buildroot, so I override blobs with wayland, https://github.com/bootlin/mali-blobs.git

10:11 <jaganteki> seems it's failed "error while loading shared libraries: libwayland-client.so.0: "

10:12 <Net147> jaganteki: do you have libwayland-client.so.0 on the system?

10:12 <jaganteki> I don't have this

10:13 <Net147> you need libwayland libraries

10:13 <Net147> it doesn't take much space

10:14 IgorPec has joined #linux-sunxi

10:21 <jaganteki> Net147, this lib is a package from waylandpp - http://lists.busybox.net/pipermail/buildroot/2017-September/201467.html

10:21 <jaganteki> but this indeed depends on mesa, we don't have mesa on allwinner I guess

10:22 <Net147> don't need libwayland++, only libwayland

10:22 <Net147> you don't need Mesa installed, libmali provides all the needed libraries

10:24 <Net147> Wayland doesn't depend on Mesa in OpenEmbedded - https://layers.openembedded.org/layerindex/recipe/5057/

10:25 <Net147> jaganteki: I don't see Mesa dependency here - https://github.com/buildroot/buildroot/blob/master/package/wayland/wayland.mk

11:14 <karlp> gonna need to be fiddling a bit with openwrt's gadget configs, to make sure the musb bits are turned on, I was getting gadget mode with no UDC available.
