Hi Folks. I was here a few days ago. I have managed to extract a sunxi.fex file from the LiveSuite image of the H3 based board I am working with.
<diskless>
This file is a dtb and I have decompiled it into a dts. I am going to modify the sun8i-h3-orangepi-pc.dts file from the Armbian supplied 4.19.25-sunxi kernel with the values I see in this dts. It has a section called dram with lines like dram_tpr0 = <0x48a192>; I do not see corresponding sections in the orangepi dts file that I am trying to modify.
<fALSO>
check if it isnt defined in the files included in that dts
<diskless>
So it looks like this dts file belongs to a legacy kernel and it programs stuff mentioned in the AllWinner H3 datasheet. How do I find what is the corresponding stuff in the H3 mainline kernel dts file to modify, to get the same effect.
<diskless>
To recap from a few days ago, when I boot the Armbian Orange Pi PC image on this board, I get only about 30% of the performance of an Orange Pi PC, even though the processor and RAM are the same. As explained by friendly folks here a few days ago, this means the processor clock and DRAM need tuning.
<diskless>
fALS0 I have picked up this file from the /boot/dts folder on the Armbian image. When I open sun8i-h3-orangepi-pc.dts in the kernel tree, it references two dtsi files. Neither of them have any mention of dram or dram_pll.
<KotCzarny>
probably uboot does it
yann has joined #linux-sunxi
<diskless>
Right. I looked at the uboot defconfig and dts, dtsi files. No dice there either. No mention of dram or pll.
<KotCzarny>
ignore it then
<KotCzarny>
and worry later
<KotCzarny>
although afair uboot has a field for dram freq
<KotCzarny>
and probably others
<KotCzarny>
just named differently
<KotCzarny>
checked defconfigs?
<KotCzarny>
it's 100% there
<diskless>
KotCzarny Yes orangepi_pc_defconfig has CONFIG_DRAM_ZQ=3881979, which matches dram_zq = <0x3b3bfb>; from this dts file.
<diskless>
It also has CONFIG_DRAM_CLK=624. I am unable to determine the clock from this dts file.
<KotCzarny>
you just use 624 or 408
<KotCzarny>
depending what ram config you have
<diskless>
Oh wait, there it is dram_clk = <0x198>; That is 408 for the CLK.
<KotCzarny>
624 is a safe value that most boards wont fail at
<diskless>
OK. So the uboot is compiled and ready. However, even before discovering this dts file, I had tried with 408, and this did not increase the performance of my board one bit.
<diskless>
I now need to figure out how to put these values into the orange pi pc dts file. All of the different values in this file.
<diskless>
Is there some place I can paste this dts fle for you guys to take a look.
<KotCzarny>
make new defconfig?
<KotCzarny>
uboot sets hw
<KotCzarny>
linux doesnt touch dram config afair
<KotCzarny>
in legacy (aw) kernels it's arisc blob meddling with clocks etc
<KotCzarny>
if you have 408, it's slower dram config
<KotCzarny>
i think it's single rank vs dual rank or something, not an expert
<diskless>
The board works with 624 too. Orange Pi has 624 and the board has been working fine with that - just slow.
<KotCzarny>
or it was ignored
<KotCzarny>
;)
<diskless>
Oh yeah. Or it was ignored. Anyway let me see with this uboot.
<KotCzarny>
i bet your main problem is lack of smp or cpu set to low speed

not sure what happened but after recent long overdue update cryptodev + libopenssl-cryptodev ended up with not working ssh / prosody ;D

on A13
<KotCzarny>
rmmod ss ?
<swiftgeek>
nah it's fine with it, just installed libopenssl and everything is back to normal
<KotCzarny>
it might be it actually started using hw crypto?
<KotCzarny>
;)
<swiftgeek>
strange it kinda worked for me
<KotCzarny>
bugs gets fixed, things stop working
<swiftgeek>
i remember running some benchmmarks to see whether it's still working
<swiftgeek>
*it's actually working
<swiftgeek>
btw what is the right tool to use to save time to rtc?
<KotCzarny>
hwclock ?
<swiftgeek>
still hwclock?

i suspect you could just echo to some /proc or /sys file too

maybe its named weirdly package

nvm just glitch probably from the other one and running over serial console

nope, just lack of window adjustment and TERM passing

+1 for using theit build system
<KotCzarny>
you can use it to build kernel alone
samrose_ has left #linux-sunxi [#linux-sunxi]
<dirbaio>
will try :)
<dirbaio>
my end goal is to get everything built with yocto/bitbake
<dirbaio>
I already got pure mainline working
<dirbaio>
but I guess first step is get a working kernel working using ANY build system :D
<dirbaio>
thanks!
samrose has joined #linux-sunxi
samrose has left #linux-sunxi [#linux-sunxi]
<megi>
kernel build can be done in a 5 line script :) the biggest work is collecting all the patches
<megi>
and config
<KotCzarny>
and in this case they can probably just be cherry-picked by name match
<dirbaio>
okay I get it now, the patches dir has patches that turn 4.19.12 -> 4.19.20
<dirbaio>
duh why didn't I see that before
<dirbaio>
that's why the version didn't match :D

jernej: why is even A64 HDMI audio not mainlined?
<mru>
because nobody did the work
<jernej>
MoeIcenowy: Issue is within I2S driver, which doesn't have support for 8 channels
<jernej>
unless you are saying that A64 I2S doesn't support 8 channels
<jernej>
I didn't check, I just assumed it does support
<mru>
i2s is a two-channel interface
<mru>
you'd need 4 of them in parallel for 8-channel
<jernej>
yeah, that's is supported on one special I2S peripheral, which is used for HDMI
<jernej>
MoeIcenowy: IIRC codekipper submitted patches for that around new year
<MoeIcenowy>
jernej: seems that A64 I2S supports no 8 chan?
<jernej>
let me check
<MoeIcenowy>
TXn Channel Select Register is 0x34 + 4n
<MoeIcenowy>
TXn Channel Mapping Register is 0x44+4n
<hanetzer>
willmore: sdk I got was legit, though it lacks an overarching document on registers and address space
