What I was worry about is that you actually wrote a frame buffer
driver, which are normally located in drivers/video, and put it in a
new directory drivers/auxdisplay. So now we have two places for frame
buffer drivers. It looks like, now some frame buffer drivers in
drivers/video should be moved in drivers/auxdisplay, shouldn't it ?
Maybe just a stupid idea but why not restructuring the thing like:
drivers
|-- display
| |-- video
| |-- aux
| |-- fbmem.c
| |-- ...
Yes, I got your idea in your first message, and well, that was
discussed (however, not being a fbdev), and the people thought that
putting them together will, maybe, cause confusion; so having them out
from drivers/video should be better. Your idea, which merge them into
a "drivers/display" could be a good one, but I don't think people will
like to change such critical tree right now. Also, I'm not the one who
maintain such tree, so my opinion won't make changes about that ;)
Another point: does the ks0108 controller is only used with the 'cfag'
display ? If not, suppose I'm using the same controller with another
lcd different from 'cfga'...Am I supposed to reuse your code in
cfag12864b.c ?
No. You are supposed to _use_ the ks0108's exported functions: I split
the code into the ks0108 and the cfag12864b because I thought it was
the logical way, as the cfag12864b LCD just send the data through two
different ks0108 controllers. The same way, you can use the ks0108's
exported functions to create another whateverlcd.c which has one or
more ks0108 controllers.
BTW, did you try to mmap your fbdev ? Does it work ?
Why it shouldn't? It doesn't work for you? AFAIK, it is a usual fbdev,
and you can map any fbdev as they are simple character file devices.
