<Ntemis>
and am thrilled to have it implemented in lakka when ready
<Ntemis>
what am curious is will the current uboot used on these devices be able to boot e.g 4.17 kernel?
<xdarklight>
great to hear that some people still care about the 32-bit SoCs :)
<Ntemis>
i am because these socs are amazing
<Ntemis>
did you know how many gflops can that gpu output?
<xdarklight>
regarding u-boot: yes, I'm using that Amlogic legacy u-boot (from 2015 or older) to boot 4.17-rc3+
<Ntemis>
hmm ok good you know that
<Ntemis>
and ythe other q is
<Ntemis>
and the other q is
<Ntemis>
what mali blobs and driver did you use?
<xdarklight>
regarding the support of the SoC itself: a big missing piece is the video output (CVBS video output is somewhat achievable, but HDMI will be VERY hard). I am currently not working on video support because it requires a lot of time
<Ntemis>
or can be used
<xdarklight>
(which I don't have at the moment)
<Ntemis>
ah :(
<Ntemis>
i sent a shematic about that to @narmstrong
<Ntemis>
let me see if i can locate it if you are interested in fixing this too
<xdarklight>
not sure if Ely wants to work on Meson8b video support - he's working on the video decoder driver, so he may want to see rendered frames at some point on Meson8b too :)
<Ntemis>
am more interested in meson8
<Ntemis>
8b is the weakest link
<Ntemis>
8+8m is what am very interested tbh
<Ntemis>
i have both socs merged into S8X2 in lakka
<Ntemis>
as the use exactly the same kernel and blobs minus the gbit lan 812 has
<Ntemis>
xdarklight: so you know , in real life tests Mali 450 MP6+2 on S802/12 is on par with an AMD HD6310
<Ntemis>
and by far thats the most powerful gpu chip in any cost effective sbc produced thus far
<xdarklight>
Ntemis: in some benchmarks (can't find the link right now) S812 was faster than GXBB (S905), so it's indeed a nice platform
<Ntemis>
trust me S905 sucks on lakka
<Ntemis>
cant play N64 core at 720p at decent frames
<Ntemis>
cant even play N64 core at 720p at decent frames
<Ntemis>
vs S802/S812 that can run at 1080p butter smooth
<Ntemis>
no frame drops
steamport is now known as steamport_old
steamport_old has left #linux-amlogic ["Leaving"]
<Ntemis>
so your "was faster" was an understatement
<Ntemis>
is million years faster that S905
<xdarklight>
Ntemis: nice :). unfortunately I'm not aware of any "real life tests" with any of the Mali GPUs
<Ntemis>
then install lakka

Ntemis: s812 is about 40% faster but it makes that much difference?
<lvrp16>
I always assumed it was some optimization issue with the emulator.

xdarklight: the vdec code can easily be ported to m8b (I started on an odroid-c1 after all), the biggest problem is, as you pointed out, DRM & HDMI.
<Ely>
well, m8/m8b/m8m2
<Ely>
it's mostly the same thing throughout all the SoCs (thank god)
