just discovered yesterday that the RK3188 does not have SATA output, and its Ethernet interface is just 10/100 (not gigabit)
<Galland>
should've checked earlier the p.brief :(
<tonikasch>
:s
<Galland>
so in the end the only alternative interface for integrating any of those is the USB2.0
<tonikasch>
ufff, 2.0 is not a good deal
<tonikasch>
:(
<Galland>
but one of the worse things is the lack of a temperature sensor inside the chip
<Galland>
there is no way to know if CPU freq should be lowered based on that
<Galland>
dangerous overclocking :S
<tonikasch>
and adding a temperature sensor and connecting it to GPIO would be a hard task, I guess
<Galland>
I was thinking on sticks, where there are no pins accessible
<Galland>
but then... radxa board is coming (RK3188 + expansion headers)
<Galland>
one of my ideas for it is to do just what you proposed tonikasch :)
<tonikasch>
o
<tonikasch>
oh, yes, in the radxa board GPIO pins are accesible :D
<Galland>
and one LCD output, and SPI/I2C, ...
<Galland>
I'm really looking forward to it
<Galland>
connect all that to a quad core CPU and 2 GB RAM and... wow
<tonikasch>
hehe, I was only wondering about customs taxes
<Galland>
hahahaha had a recent experience with that
<Galland>
almost doubled my purchasing price for some components :(
<tonikasch>
yeah, a year ago I bought a chinese mobile phone and, well, I didn't have to pay as much as the double, but somehow something expensive for me
<Galland>
this tool is done by one of the top contributors to linux-sunxi's fb driver
<Galland>
top notch developer
<Omegamoon>
Ah, it's Spanish? ;-)
<Galland>
telefono :D
<Omegamoon>
It sound like a nice acceleration
<Omegamoon>
Haven't looked into the sunxi fb code
<Galland>
I'm currently using the sunxi fb driver on the rk31 (NEON)
<Galland>
and no problem at all
<Omegamoon>
Would it need extra adjustments to make it work on the rk31?
<Galland>
can't "feel" much of a difference from the default one, but the NEON thing lured me in
<Omegamoon>
Ah, that's a no then
<Galland>
and it's being actively developed
<Galland>
if we can some day snatch the "RK3188 RGA.pdf" or "RK30xx RGA.pdf" (2D accelerator IP core)
<Omegamoon>
But it's no hatdware accelleration...
<Galland>
we could add a module for it, they've coded it very nicely to do that
<Galland>
RGA is actually used for accelerating 2D operations like scaling
<Omegamoon>
Hatdware... Hardware I mean
<Galland>
RGA is an IP core within the RK3188/RK3066, it's hardware
<Galland>
just read it yesterday on the TRM
<Galland>
and p.brief
<Galland>
the sunxi fb driver is very nicely coded
<Galland>
for example, the 2D accelerator in Allwinner chips is accessible as a module (sunxi_x_g2d.c)
<Galland>
same could be done for RK's RGA
<Galland>
if only we had the docs...
<tonikasch>
hey, sorry, I was on the phone
<Galland>
np ;)
<tonikasch>
docs, docs, docs... or that git source code :P
<Galland>
you mean the bugged source code? :D
<tonikasch>
yes... but perhaps the full source code
<Omegamoon>
The full source code...
<Omegamoon>
Life would be so much easier... If only we had the full source code of it
<tonikasch>
yes...
<Galland>
actually something may be inferred from the code: ./drivers/video/rockchip/rga/
<Galland>
that's better than nothing
<Galland>
I particularly like rga_reg_info.c
<Galland>
exposes clean and intersting functions

RK30XX TRM p.736: "Chapter 23 - RGA: RGA is a separate 2D raster graphic acceleration unit. It accelerates 2D graphics operations, such as point/line drawing, image scaling, rotation, BitBLT, alpha blending and image blur/sharpness."
<Galland>
and p. 695: "Chapter 21 - IPP (Image Post Processor): Image Post Processing (IPP) is used doing image scaler, deinterlace and rotation. Each processing can be done independently or combined with others."
<Galland>
both can scale and rotate hmmmm
<Galland>
"For detailed information about RGA,please refer to RK30xx RGA.pdf."

Gotta love that
