Re: [Linux-fbdev-devel] [PATCH 1/1 2.6.13] framebuffer: bit_putcs() optimization for 8x* fonts

The special case for s_pitch == 2 saves about 270 ms system time (2120 ->
1850ms)
with a 16x30 font.

Compared to what? How much is the function call overhead?

Your version of the inline code inserted after an if (idx==2) in bit_putcs against my version of the

inline code.
