<montjoie> for a real rpi, the gpu will be connected over usb:)

<paulk-leonov> wens: not sure it outperforms rk3399 though
<wens> paulk-leonov: it doesn't have to outperform with its price point
<wens> huh... googling for rock pi produced an article from January that says "Rock Pi 4B outperforms Raspberry Pi 4"
<paulk-leonov> yeah, although once again it will sadly be held up as one of the best devices out there despite its lack of ability to function at all with free software

<libv> paulk-leonov: it's amazing how that bs has been kept up for the last 7 years
<paulk-leonov> yeah, especially given the resources they have available
<paulk-leonov> but well, different priorities...
<wens> reviews say playing youtube fullscreen is jerky
<wens> sounds more like a problem with the software stack than anything else
<jernej> are there any web browsers which use HW accelerated video decoding? AFAIK no, except if you use out-of-tree patches
<jernej> I think having problems with yt in browsers is normal for any SoC
<wens> jernej: only one I know of is the patched Chromium from RaspberryPi Foundation
<KotCzarny> goebbels would be proud of all marketing scams
<wens> and that only patches decoding, not the whole display compositing/blitting side
<jernej> yeah, although they use mesa for RPi4, so at least with compositing they shouldn't have much issues
<paulk-leonov> jernej: well, except there's a chance GPU is a bottleneck for 4K
<paulk-leonov> and obv there's no plane integration
<paulk-leonov> although the rpi has many planes available
<jernej> ah, true
<wens> jernej: does mesa already support the new GPU?
<jernej> yes
<wens> that was fast
<paulk-leonov> wens: it's v3d
<paulk-leonov> which was integrated a while ago
<paulk-leonov> there's also a kernel-side driver around already
<wens> oh. I thought that was videocore 5, while rpi4 is vc6
<paulk-leonov> rpi4 is vc5
<wens> ok, then some chart listed it wrong :p
<paulk-leonov> probably :)
<jernej> no, everyone is talking about VideoCore VI, but that seems to equal vc5
<jernej> so everyone is confused if it is 5 or 6
<paulk-leonov> I can tell you for sure it's vc5
<paulk-leonov> but don't ask me how I know :)
<jo0nas> is that a marketing stunt too? "VI isn't the rmal presentation of 6 but another spelling of 5" ;-)
<jo0nas> roman*
<jernej> paulk-leonov: I have pretty good idea how you know :)
<jernej> anyway, now they promised v4l2 HW decoding driver
<wens> v4l2 still doesn't have support for MMAL decoding though, so one still needs the patched version for video decoding
<paulk-leonov> yeah their MMAL stuff is quite horriblre
<paulk-leonov> horrible*
<wens> there were patches against mainline floating around. don't know what happened
<paulk-leonov> I've worked on it a bit, it's a long way there
<paulk-leonov> it's not mainline-compliant
<paulk-leonov> at this point
<paulk-leonov> the whole MMAL thing is a mess too
<wens> IIRC the initial version was just moving the MMAL stuff in-kernel
<wens> similarly to what was done for the camera
<paulk-leonov> it's also not native but firmware mailbox as usual
<paulk-leonov> wens: but they do have a native propert driver for the camera in development
<paulk-leonov> but not for the codec side yet
<paulk-leonov> proper driver*
<wens> native, as in not firmware mailbox, or not-MMAL ?
<paulk-leonov> both IIRC :)
<wens> sounds good
<paulk-leonov> like, it actually writes to hardware registers
<wens> but then it wouldn't be doing encoded H.264 output, right?
<jernej> well, current LibreELEC 10 goal is to use v4l2 driver for video decoding on RPi
<wens> because that was done by the firmware handling the pipeline
<jernej> and Kodi 19 goal
<jernej> and get rid of all MMAL stuff
<wens> I still have trouble understanding Kodi, LibreELEC, *ELEC
<wens> AFAICU, Kodi is the player itself, and *ELEC is the distro or image around it?
<jernej> LibreELEC is just minimal distro to run Kodi
<jernej> yes
<jernej> it fits in about 100 MiB compressed

<wens> hmm, bcm2711 moved to 28nm instead of old 40nm process
<wens> w/ PCIe connecting the USB 3.0 hosts
<fALSO> lol
<wens> and proper internal GbE controller
<fALSO> everyone is crayz with the new rpi today
<fALSO> crazy
<wens> at least they're learning? :p
<KotCzarny> if they dont cripple it and keep the low price, it would be a killer
dddddd has joined #linux-sunxi
<KotCzarny> lets hope they b0rk it similar to aw ;)
<wens> KotCzarny: I don't think it would matter, at least until they come out with a compute module where you can use the PCIe lanes yourself
<wens> KotCzarny: but b0rking it like aw is a huge fail :)
<wens> fALSO: likely because they've been dragging their feet in terms of performance? :p
<fALSO> lol
<fALSO> i wish there was an orange pi reseller in europe
<fALSO> so i could buy the options with moar ram
<fALSO> because otherwise the portuguese customs will rob me :-P
<wens> has the EU increased tariffs against China as well? or was the duty already high? :p
<karlp> I'm not sure I follow how you only get robbed on the higher ram version?
<karlp> what would a local reseller get you othe than potentially faster shipping?
<jo0nas> perhaps s/reseller/smuggler/ ;-)
megi has joined #linux-sunxi
<wens> lol
suprothunderbolt has quit [Ping timeout: 245 seconds]
<fALSO> if something passes over 25€
<fALSO> we get robbed bu the customs in portugal
<fALSO> they just invent taxes
<wens> I doubt the reseller would be able to bypass that
<fALSO> ya :-X
<KotCzarny> wens: in .pl you can get slapped by vat (23%) and customs if you order more expensive stuff
<fALSO> i wish that in portugal we had something to PRE-CALCULATE
<fALSO> what we are going to pay beforehand
<KotCzarny> but oftern packages go unslapped
<MoeIcenowy> hope it can be an end for All 7/53 Winner
<MoeIcenowy> ;-)
<KotCzarny> naah
<KotCzarny> opipc rulez :>
<Hellsenberg> opi is nice
<Hellsenberg> even if not high-end (2 GB max ram I think) it's reasonably priced

<megi> I don't see holes for the heatsink on rpi4
<megi> will be fun to cool
<wens> stick-on heatsink
<megi> those are usually quite small
<buZz> probably just throttles down like mad
<megi> I'd guess so, too
<buZz> like pi2 and 3 do
<megi> no holes
<megi> I don't think they worry for cooling that much

<[TheBug]> From what I read they made it to progressively throttle so it doesn't get too hot, so unless you have some cooling it most likely is always throttling
<Mangy_Dog> im currently working on a project
<Mangy_Dog> not tested it yet, but seriously considdering this fan
<Mangy_Dog> and a heat sink
<Mangy_Dog> tiny thing with some air movment
<Mangy_Dog> might do the job
<Mangy_Dog> better than passive cooling inside a chassis with no airmobment
<Mangy_Dog> even with a sink
<Hellsenberg> heatsinks help

<lvrp16> My Pi 4 idles at 550mA :O
<lvrp16> Up from 350mA
<lvrp16> They basically used every bit of die space saved from moving to 28nm on the A72 cores.
<veremitz> I believe there's actually a lot more transistors in that core .. with all the other peripherals ..
<veremitz> which is a welcome change
