[Qemu-devel] PL110 1bpp and 2bpp fix

[Justin Fletcher]

Hiya,

Tiny fix for the bit manipulation in the PL110 rendering code, 
hw/pl110_template.h. There is a sequence of three definitions used in the 
graphic routines :

#define FN_2(x, y) FN(x, y) FN(x+1, y)
#define FN_4(x, y) FN_2(x, y) FN_2(x+1, y)
#define FN_8(y) FN_4(0, y) FN_4(4, y)

In the FN_4 definition, the second entry should read x+2, rather than x+1. 
With x+1 we get bits in the wrong order - it's just about usable, but it's 
not right. This only affects 1bpp and 2bpp modes.
