Ok,
So fresh news and summary.
Many many thanks to Sergio Costas for his work and assistance. He wrote and
published FW extractor. I suppose it will be useful for someone trying to
make it works GSL1680.
In my case, Chuwi Vi8 super (baytrail architecture) it looks that chinese
developers put in this tablet touch screen with higher resolution than
display resolution.
It means that what I have extracted from .ko elf file from the begining and
what I have taken from Win 8.1 Silead.fw and what I've got with Sergio
Costas's extractor - all these firmwares returns weird resolution
11145x1725 (may be allittle mistake ;-) due my fingers, but I think that I
note it as correctly as I can).
So, in case for Chuwi Vi8 super, baytrail architecture - the solution is
still the same - add rescaling correlation to Sergio Costa's user space
driver.
Also I have not yet analyzed all working firmware files that I have but for
me it looks weird that different size firmware works in the same manner.
(in case of user space driver it is important the size of FW because the
more it is the more its time consuming for loading it).
It will be good to disassemble firmware for GSL1680 to understand what is
it, I saw in some variants of firmware some comments to some portion of
bytes (unfortunately in weird char layouts, probably chinese or closely).
With best regards,
Serge Kolotylo.
