Introduction[edit | edit source]

Vesa modes operates on system memory (all bitmaps are stored there), which, in read operation, is much much much faster than the video memory accessed by CPU.

For a start just hack vesa.hidd from x86 native (arch/i386-pc/drivers/vesa.hidd/*).

Add some code which setups some visible area in chipram and then modify vesaDoRefreshArea() to do a chunky to planar conversion into those bitplanes.

You could probably "patch" in emulation in the x11 drivers setattrs function.. see
