anyone know how to override CONFIG_SYS_CONFIG_NAME? Trying to add a different header file to a board.
<
lvrp16>
but MACH_SUN8I is overriding the defconfig everytime
<

mach-sunxi is setup a little differently than other plats

anyone know if upstream u-boot supports gadget mode?

AFAIK it should for A83t and before, never tested anything after that myself

wens: do you know which usb config i need for h3/h5?
<
wens>
lvrp16: you want to enable USB_MUSB_GADGET instead of USB_MUSB_HOST, and then whatever gadget commands you need, like fastboot and co.
<
wens>
also you might need to tweak the device tree to have dr_mode = "peripheral" if it was "host"
<
lvrp16>
Gotcha thanks. It is all funky with different boards haha.
<

Can that be done live?

<
mru>
sunshavi: yeah, something clearly isn't quite stable
<
sunshavi>
yeah. Now I am in 1.1 Ghz. I am going to test it for a week. and see how it goes
<
sunshavi>
thanks for your help. probably. I am the first one on archlinux with this thermal commit on dts ;)
<
mru>
on the thermal side, /sys/class/thermal/thermal_zone0/cdev0/cur_state tells you if the clock is reduced
<
mru>
normally the value is 0
<
mru>
if it's not 0, it's trying to lower the temperature
<
sunshavi>
it is still zero
<
mru>
there are some config options to track statistics
<
mru>
so you can see how often it throttles
<
mru>
even if it's not doing it right when you look
<
mru>
CONFIG_THERMAL_STATISTICS
<
mru>
that gives you a few more sysfs entries
lurchi_ is now known as lurchi__
<
mru>
ok, then you should have some statistics under /sys/class/thermal/thermal_zone0/cdev0
<
mru>
yes, the 'stats' file

mru: it hanged in the middle of our conversation
<
mru>
now load the cpu
<
mru>
see what happens when it hits 80°C
<
sunshavi>
just 60 degress
<
sunshavi>
then. I am going to play music
<
mru>
are all 4 cores busy?
<
mru>
you need more cpu load
<
mru>
a stupid shell loop will do
<
mru>
while :; do :; done
<
sunshavi>
just one core at 100%
<
mru>
yes, so run 3 more of those
<
sunshavi>
i am going to play a video then
<
sunshavi>
all the cores at more than 90%
<
KotCzarny>
if you want to load the cores, cpuburn-a7
<
sunshavi>
80 degres
<
sunshavi>
trans_table stays on zero
<
mru>
what does time_in_state_ms say?
<
mru>
so it is throttling now and again
<
mru>
for some reason the transition table doesn't seem to update
<
sunshavi>
yes. it is still the issue. perhaps this patch needs something additionally
<
mru>
if you watch the time_in_state_ms file, are the values increasing?
<
sunshavi>
this group of files are not changing anything (after boot)
* willmore
seconds cpuburn
<
sunshavi>
well i am going to stop video and try cpuburn
<
sunshavi>
Btw: 82.3 degress
<
mru>
that should make the throttling kick in
<
KotCzarny>
with cpuburn its possible to move h3 to 90-110C
<
KotCzarny>
wget + gcc = binary
<
hell__>
that looks like how to space heater an ARM chip
<
sunshavi>
ok on the process of making a binary
<
sunshavi>
it is going to take a little bit of time (son asking for help)

we are in the same boat. which kernel version?
<
mru>
5.4 with some backports
<
mru>
I don't care that much about the stats
<
mru>
I've verified that it does the right thing
<
mru>
by heating the chip and seeing the cpu frequency drop
<
sunshavi>
then I could have done the same
<
sunshavi>
KotCzarny: this is assembler? cpuburn-a7.S
<
KotCzarny>
sunshavi: see the beginning of the file for commmand to compile it
<
sunshavi>
KotCzarny: ok
<
sunshavi>
should I turn on my opipc. And try this there?
<
mru>
do you have a hot air gun?
<
mru>
or a hair dryer
<
sunshavi>
probably my wife has one
<
sunshavi>
ok running cpuburn
<
mru>
watch the temp and clock freq
<
mru>
if the temp hits 80°C, the clock should be reduced
<
sunshavi>
frequency is working
<
sunshavi>
now. there is different frequencies on each processor
<
KotCzarny>
keep in mind you will have to run 4 of those burners
<
KotCzarny>
to load each core
<
mru>
KotCzarny: the burner forks
<
KotCzarny>
it does?
<
KotCzarny>
long time ago it wasnt implemented
<
mru>
half an hour ago it was
<
mru>
no idea when it was added
<
sunshavi>
It seems. some things change other no. Quotin 'morfeous' from matrix
<
mru>
if you stop the burner, does the frequency go back to max?
<
sunshavi>
let's see
<
mru>
all cores run at the same frequency, btw
<
sunshavi>
Yes. It does
<
mru>
it probably adjusted the max rate while the command was running
<
mru>
seems to be working correctly then
<
sunshavi>
Yes. It is Sir
<
sunshavi>
I am going to see what happens next days. I need back my uptime of months
<
mru>
longest uptime I ever had was about 3 years
<
sunshavi>
that's too much for me. I change it on every kernel release
<
sunshavi>
two months regularly
