Assuming "i.MX8 Mobile" is i.MX8M then it is a Vivante GC7000 Lite (OpenGL ES 3.1)That sounds nice! What GPU does it have?
Not sure if I posted this before, but have you had a look at the Rockchip RK3399? Collabora has worked on making the reverse engineered GPU driver work and it seems like a good open source platform.
Eight Bit posted this before, maybe I should read a thread before posting in itI've been very happy recently, running Manjaro Linux 64 bit on my Pinebook pro (much happier than I was when it ran Debian) which sports a rockchip RK3399 SOC with Mali T860 MP4 GPU. Now I'm no expert on SOC's and the PBP is surely not a gaming device but Manjaro seems to run quite decently with the latest kernel. I now even have 32 bit chromium running in a docker container so I can use Wiidevine for watching and listening to DRM content like spotify and netflix and it works great. I feel it will only get better as it did with the Pandora.
So maybe that or the RK3399pro are worth considering as it would be easy to surf along on already made efforts in regards to the software?
Honestly? That sounds like a lot of headaches and effort for next to no gain. I just don't see many existing users switching and if the difference is barely there, it wouldn't really get us many additional either.
HardKernel have uploaded some fairly good documentation here: https://dn.odroid.com/S922X/ODROID-N2/Datasheet/S922X_Public_Datasheet_V0.2.pdf too, not as good as something like the iMX8 but a start.What about Amlogic S992X?
It's the one odroid N2 uses.
And it's Cortex A73 instead of A72. So it's a lit more power efficient than the Rockchip
We're talking about the i.mx mini or mobile or whatever.The A72 on the i.mx8 is really not that powerful compared to the A15 in the actual omap?
It is like two generations ahead the A15. I thought there would be a huge difference. But well, I know nothing about this things.
I'd rather throttle down "big" cores instead of not having them at all.HardKernel have uploaded some fairly good documentation here: https://dn.odroid.com/S922X/ODROID-N2/Datasheet/S922X_Public_Datasheet_V0.2.pdf too, not as good as something like the iMX8 but a start.
But I'm still a bit worried as to whether a TV-box SoC will be power optimised enough for this use case
Indeed, it looks like power to the A73s can be turned off, so as well as power benefits people who want in-order only for security can just use the A53s and ignore the A73s.I'd rather throttle down "big" cores instead of not having them at all.
Having high peak performance is important for desktop usage.
We don't need to run them at full speed all the time.
I'd even prefer being forced to use an older Kernel because of driver issues instead of having a SoC without "big" cores.
We don't need to deliver as much performance than GPD does, but having some more power when needed is not a bad thing
One more thing not mentioned here:
The i.mx has one more advantage over the OMAP 5 : it is 64-bit.
However, it would not justify the effort for me.
I can't find any pinout or register level documentation for any of the Mediatek SoCs, presumably it is under strict NDA and hasn't leaked. I suspect availability could be an issue too.What about the MediaTek Helio SoCs?
Are they easily available and well documented?
They have Cortex A75 and A76 SoCs.
