Net147_: are you planning to update a10/a20 display support patches?
<Net147_>
wens: I think they need rebasing on top of your A31 work
<wens>
likely yeah

should I wait until the A31 stuff gets applied?

into sunxi-next
<wens>
you can just base it off my a31-hdmi-v3 branch

it has some extra patches that I haven't finished or sent, but it shouldn't affect your work

@Net147, is there any DTS with the dual DRM pipeline setup, in your branch 'sun7i-drm-wip', so i can wrap my head around the correct setup..
<sunxi_fan>
i have this A20 EVB with RGB and HDMI, i'd like to see working on a dual framebuffer..
<sunxi_fan>
BTW, i'm wondering if such a dual head setup will work smoothly with the recent exploit of libMali.so on mainline..

I'm running the latest upstream u-boot with h2+ board and Display Engine 2 video driver but I don't know how to get the U-boot logo showing up on the HDMI monitor! I tried to find relevant setting from menuconfig but I didn't notice any.
chomwitt has quit [Ping timeout: 258 seconds]
<jernej>
Putti: Which U-Boot logo?
<Putti>
I remember there being one that shows up at the very first thing when you boot, or is it some custom stuff on the boards I have seen the logo on?
<Putti>
I rgrep'd the u-boot source code and found CONFIG_VIDEO_BMP_LOGO so I think it might be that
<Putti>
jernej, and thanks for the great work with HDMI support
<jernej>
old video framework showed Linux penguin
<jernej>
but that's not default anymore with DM video framework
<Putti>
oh, such a bummer
<jernej>
I think you can still show some image
<jernej>
if you want
<Putti>
yeah, I think I saw some instructions on the internet on getting splash screen working for u-boot so I guess I could have that show the penguin :)
<jernej>
btw, penguin image was hardcoded in, so you have to use some other mechanism, like loading image from filesystem
<smaeul>
which is accurate: the board has been on about 3 days

@smaeul, is it a arm64 board ? I've faced that too recently ... I've rebuild my kernel with CONFIG_FSL_ERRATUM_A008585=y and "fsl,erratuma008585" in DTS, now checking it is will last forever...
reinforce has joined #linux-sunxi
Mr__Anderson has joined #linux-sunxi
<martinayotte>
Oupps ! Typo missing dash : "fsl,erratum-a008585" in DTS
<martinayotte>
BTW, when such bug occurs, there is no way to adjust sys_clock, neiher with date/ntpdate/hwclock, even if "hwclock -r" retrieve good value, the kernel doesn't let any do settimeofday() and returns EINVAL. Only reboot fix the issue ...
<smaeul>
martinayotte: yes, it's opiwin, so A64
<martinayotte>
If you are using Armbian, I've committed a patch yesterday !
<smaeul>
date: cannot set date: Invalid argument
<smaeul>
so it looks the same as what you're experiencing
<martinayotte>
Right ! settimeofday() and returns EINVAL
<martinayotte>
You're welcome ! Have an happy rebuild ... :-P
<martinayotte>
I think owner of settimeofday() should look why we cannot fix the clock and bug occurs ...

sunxi-h3-h5.dtsi (linux-next) has in usb_otg 1K memory size instead of 4K. USB OTG in H3 at least according to datasheet has 4K address space. I noticed similar "bug" in some other node some time ago and I think someone even sent a patch for it but I don't remember if there was any other reason to fix this other than cosmetics.. So if someone could remind me again?
lkcl has quit [Read error: Connection reset by peer]
<martinayotte>
@Putti, but this is related to EMAC, not USB_OTG ...
<Putti>
right but similar problem
<Putti>
I wonder where the wrong sizes came in the first place, maybe copy paste from somewhere?
<Putti>
though, if one is looking from the datasheet it could be easy to read the value from one row above or below
vagrantc has quit [Ping timeout: 260 seconds]
<martinayotte>
In 4.11.x, it was also 1K
<martinayotte>
Which pageNo that you found the 4K ?
<Putti>
martinayotte, 84
<martinayotte>
Right !
Andy-D has quit [Ping timeout: 240 seconds]
jernej has quit [Ping timeout: 248 seconds]
vagrantc has joined #linux-sunxi
<martinayotte>
I think it is related to the fact that not all registers are needed, for example, EHCI0 and OHCI0 together on page 84 says also 4K but in DTS, they are splitted with each 256 bytes.
<martinayotte>
In other words, there are many unused address spaces...
scream has quit [Remote host closed the connection]
<Putti>
yes
<martinayotte>
Details for those are at page 488, even 256 is big since their last register are at 0x54. I bet that OTG is also ending at 0x54 ...
SP7RT_ has quit [Ping timeout: 258 seconds]
<Putti>
are the OTG registers documented anywhere?
IgorPec has joined #linux-sunxi
<martinayotte>
I don't see them on page 486/487, I presume it is the same register list as EHC0, but at address 0x01C19000, therefore also ending 0x54
<martinayotte>
Important thing is not to map larger than reality : I remember tweaking LongSleep DT almost 2 years ago where EMAC was larger than reality and it was preventing using other peripherals next to EMAC, if I remember SPI0/SPI1.
SP7RT has joined #linux-sunxi
<Putti>
How was it preventing?
<martinayotte>
My memory troubles, but if I remember, SPIs were not discovered.
<martinayotte>
That was on early Pine64
<Putti>
but shouldn't it work in theory? So could there have been some bug in the datasheet or hardware? Or even a bug in the kernel?
<martinayotte>
In this case, instead of reserving 64K for ETH, it was wrongly reserving 256K, overlapping at peripherals found after ETH location.
<martinayotte>
(so, it was not 2 years ago, but 14 months ago ;-) )
IgorPec has quit [Ping timeout: 260 seconds]
BenG83 has quit [Ping timeout: 240 seconds]
<Putti>
mhm but what if we don't specify all the memory space available in DT: couldn't that then make possible some hard to debug bugs? Like maybe some driver changing the registers of some device that doesn't belong to it? Or does the kernel do any checking like this?
SP7RT has quit [Ping timeout: 258 seconds]
Mr__Anderson1 has quit [Remote host closed the connection]
<martinayotte>
In the current example, if the driver doesn't access any location outside 0x0000 and 0x0054, why would it be important that have the whole 4K mapped in DT ?
<martinayotte>
In the case of overlap issue I've mentioned, I had really problems not been able to use the SPI because of EMAC stealing the whole space.
<martinayotte>
If you wish to play with this, simply change DT to have EMAC stealing 256K ... :-)
<Putti>
martinayotte, I think at least what mripard said (in the log I linked) has some truth to it but it would be interesting to ask this same question on some more general kernel mailing list because maybe people there have some more good arguments for what should be the specified register size.

hey guys, i am searching for help since a few days to get my banana pi with archlinux installed booting from my hdd again
<andre4s>
need some uboot support
<andre4s>
i have had the leemaker archlinux installed which have been shipped with the old uboot and made mi bananapi booting fine from my sata hdd configured with changing the line of the root device in the uEnv.txt
<andre4s>
now i reinstalled the archlinux folowing this tutorial https://wiki.archlinux.org/index.php/Banana_Pi and compiled uboot by myself out of the git sources and my archlinux is booting fine with the boot.cmd of the tutorial from my sdcard
<andre4s>
but now i am stugging make it boot from my sata hdd again
<andre4s>
i researched for tutorials howto configure the boot.cmd to make my archlinux boot from sd but without any success
