smaeul: thing is, i have an arm-linux executable that loads and boots arisc blob
<KotCzarny>
which works, but somehow i fail at setting mem contents in the blob (hacky config without msgbox)
<KotCzarny>
in another news, anyone wants arm binary that does fake shutdown that turns off almost all soc subsystems and waits for gpio or ir button to wake
tllim has quit [Ping timeout: 272 seconds]
<KotCzarny>
power draw is down to 40mA in that mode
<KotCzarny>
probably i should hunt down more clocks/regs
tl_lim has quit [Read error: Connection reset by peer]
<anarsoul>
KotCzarny: what soc?
<KotCzarny>
h3
<KotCzarny>
but can be modified for any arisc capable one
<anarsoul>
so does it mean working suspend on mainline kernel?
<KotCzarny>
not suspend, it's emulating 'poweroff' functionality
<anarsoul>
oh, I see
<KotCzarny>
it can be modified to restore clocks, but again, might be tricky with mainline atf
<anarsoul>
so why not to cut power using axp?
<KotCzarny>
H3
<KotCzarny>
;)

for suspend i suspect one could try modifying atf to set/unset supesuspend flag on some hw event

KotCzarny: what do you mean "setting mem contents in the blob"?
<smaeul>
like you're trying to modify the arisc binary from arm?
<smaeul>
while it's running or something?
<smaeul>
and by blob do you mean aw's blob or something you made?
<KotCzarny>
no, i wrote arisc program, compiled it, then i'm adding it as a blob to arm-linux binary, which then loads and boots arisc
<KotCzarny>
i write the blob from linux at 0x40000 (48kB)
<KotCzarny>
i've also written test code to write 1 word at every kB in the arm-linux loader, but then when i read that mem from arisc it doesnt seem to show written values
<KotCzarny>
fw works, so it's not a problem with writing mem
<KotCzarny>
maybe arisc program does something to available mem
<smaeul>
and you're aware that 0x40000-0x50000 is mapped to 0x00000-0x10000 in arisc address space?
<KotCzarny>
oh.
<KotCzarny>
figures.
<KotCzarny>
big thanks!
<smaeul>
because the reset vector / exception vectors have to be at zero :)
<KotCzarny>
pity i didnt ask you yesterday, lost few hours trying to make it work
<smaeul>
what kind of docs are you looking for? https://openrisc.io/or1k.html is the manual for the architecture, handles exceptions/timer/SPRs pretty well
<KotCzarny>
well, any allwinner specification/gotchas
<smaeul>
the source code for their blob is in an encrypted tarball in the sdk :P
<smaeul>
there's not really any docs about the arisc itself

Anybody familiar with H5 willing to walk me through a bit how to build and set up a kernel for Orange Pi Prime (H5, and kernel for Gentoo). Like patching HDMI support (or using the armbian repos) and configuring the device tree and U-boot stuff? I know it's a lot to ask but because I'm not too experienced with how it works this deep under the hood, it's kinda what I have to do...

I've converted sun7i-a20-olinuxino-lime.dts to use axp209.dtsi instead of the partial axp209 node, now I've enabled and tested ac_power_supply and battery_power_supply but I'm not so sure about usb_power_supply
<merlin1991>
what would be correct tree to get those changes into mainline?
