Dear All,
My query is, in an embedded linux os, how graphics is handled?
To my knowledge, Bottom-most layer must be hardware. What is above it? Device driver from hardware vendor? Then, on top of it, is there a hardware abstraction layer? To provide drawpixel, drawline, draw circle etc to upperlayer? Then, I think, other applications/windowmanagers shall be there...
This is just my idea. Got from general OS principle books. Am I wrong?
Please help, how generally graphics are handled in an embedded linux os. From where, we shall expect drawpixel, drawline, drawcircle etc functions?
Sincerely, Srinivas Nayak
