00:02 <swabbles> I think you are just supposed to do something like: var_info.xres * var_info.yres * var_info.bits_per_pixel / 8.

00:03 <swabbles> For the screen size.

00:03 <swabbles> ssvb: ^

00:04 <ssvb> swabbles: that's the 'var' info, which means that it can change if you change the video mode using the appropriate ioctls

00:04 <swabbles> Ah, well that's inconvenient :/.

00:05 <ssvb> well, it is likely that the exynos fbdev driver does not support the mode setting ioctls, so it could be actually safe

00:06 <ssvb> but piling up the workarounds is annoying

00:13 <swabbles> fbset -xres 800 -yres 600 just changes the tty area that is being used (clear only clears the upper-left 800x600 area).

00:13 <swabbles> But it does influence the "screen size" calculation.

00:18 <tfiga> ssvb: line_length * yres(_virtual)?

00:20 <tfiga> although I'm not sure what's wrong with exporting smem_len
