Vesa LFB memory area size

Post by micron »

Is there a way to determine the size of Vesa LFB physical memory usage ?
To my understanding atleast some graphics cards use more than (scanline*Yresolution) of physical memory.
Vesa info block has offscreenmemoffset and offscreenmemsize variables,
which in vbe 3.0 seem to be (always?) set to zero ?

You can get such information from PCI BAR of the display card (if it is not too ancient and support PCI).
