<markvandenborre>
and thought that you might have something interesting to say about the bpi's 3.5" LCD (parallel rgb, ...)
<markvandenborre>
and running it on a mainline kernel
<markvandenborre>
as you might have heard on this channel, or from other people involved in the sunxi project, at FOSDEM we use this configuration in our video setup for historical reasons
<markvandenborre>
we have a working legacy kernel setup, but we're looking into using mainline
<markvandenborre>
the LCD is the only blocker at the moment
<ullbeking>
He's saying that the idle temperature with the latest Stretch is much lower
<ullbeking>
Maybe this will help the rev 1.4, I don't know

I'm going to see if I can return my rev. 1.4 OPi Zeros. If they need heatsinks, active cooling, or water cooling when idle, that's just stupid. This is supposed to the be the simplest, easiest, Xunlong board, kind of like the reference standard, and simple too. I don't have time to worry about extra cooling solution in addition to learning everything else.

P.S. the NS1068X UAS mode doesn't work on a RK3328 board
<icenowy[m]>
I wonder whether it will work on H6
<icenowy[m]>
(but I doubt whether the H6 BSP 3.10 kernel supports UAS ;-)
<tkaiser>
icenowy[m]: Those Norelsys chips work nowhere. I bought one by accident and donated it to upstream Linux UAS maintainer to get it UAS blacklisted everywhere.
<wens>
lol
<KotCzarny>
lol
<tkaiser>
icenowy[m]: Does your friend with the R1 measured temperatures on his board?
<icenowy[m]>
tkaiser: is NS guys blacklisted already?
<tkaiser>
icenowy[m]: When I checked last time (August) both problematic chips weren't blacklisted. But the 'reporting process' on Linux isn't really great (especially compared to Microsoft and Apple who buy every USB peripheral, test and add a quirk/fix to their drivers within weeks)
<icenowy[m]>
I think maybe we should submit patches directly ;-)
<icenowy[m]>
it's community-driven ;-)
vagrantc has quit [Quit: leaving]
<icenowy[m]>
however the NS1068X I have is something mysterious -- it works on XHCI on my ThinkPad E531 laptop, but do not on the USB3 port of RK3328 (Rock64)
<icenowy[m]>
and only on USB3 ports it can be probed as UAS
<icenowy[m]>
(on USB2 ports it's only probed as BOT
<wens>
pwm seems broken on a20
<awais_>
icenowy[m]: Isn't is expected? No UAS in USB2 specs
<icenowy[m]>
awais_: it's not expected. UAS is a new protocol in USB3 spec but it can also run on USB2 bus
<icenowy[m]>
and provide better performance than BOT even on USB2 bus
<icenowy[m]>
tkaiser: do you have any archive of reporting norelsys issue to USB Storage maintainers?
jelly-home is now known as jelly
<tkaiser>
Nope, I sent an email to Hans asking for advise, he told me that he's not UAS maintainer any more and then I got in contact with Oliver directly (sitting 180 km away from me at Suse)
<awais_>
icenowy[m]:You are right. Might be the device firmware switching to BOT on detecting USB2. Looking at USB descriptors might shed some light
<icenowy[m]>
180km is so near ;-)
<icenowy[m]>
if he's not the maintainer the comment in unusual_uas.h should be fixed

Got a lot of help of messages from icenowy[m] in this channel. Thanks :)
<icenowy[m]>
interesting... I don't think I helped you at all ;-)
<icenowy[m]>
tkaiser: suddenly I found that I have two kind of Norelsys disasters: one 2537:1066, another 2537:1068
<tkaiser>
icenowy[m]: Yes, they're similarly broken. On all ayufan and Armbian images they are blacklisted now by default and there's a routine checking also for external Seagate and WD disk enclosures to blacklist them too.
<icenowy[m]>
Armbian uses extra patches for blacklisting them?
<awais_>
icenowy[m]: Do you remember how many fps you got on Mali-450 H5. I seem to get no more than 55 fps currently.
<icenowy[m]>
awais_: 4fps is due to MMU issue

I know it ;-)

icenowy[m]: I used your PMU macro work-around. Got 55 fps after that
<icenowy[m]>
I used it to blacklist the 2537:1068 to test USB3 on my R64
<icenowy[m]>
awais_: there's a GL_OUT_OF_MEMORY problem I didn't solved on H5
<awais_>
icenowy[m]: I haven't seen the GL_OUT_OF_MEMORY during my testing. Though I mostly tested with wayland blob only.
<icenowy[m]>
when running big programs
<icenowy[m]>
have you tried to run a weston?

icenowy[m]:The es2gears and mplayer in the image are both running on weston

the "of course it's wrong" part
<tkaiser>
wens: But it's like this :) We look in the fex, read 672, do copy&paste while the BSP uses other values and downclocks DRAM starting at 624 MHz depending on overheating :)
<tkaiser>
With FriendlyELEC it's even worse. They provide fantasy values in their own Github repos, use a proprietary board detection logic and set DRAM clockspeed to eg. 408 MHz while we pick the wrong 672 MHz and submit this upstream. Could be funny...
