This is what I found in savagefb.c
static struct fb_var_screeninfo __devinitdata savagefb_var800x600x8 = {
accel_flags: FB_ACCELF_TEXT,
xres: 800,
yres: 600,
xres_virtual: 800,
yres_virtual: 30000,
bits_per_pixel: 8,
pixclock: 25000,
left_margin: 88,
right_margin: 40,
upper_margin: 23,
lower_margin: 1,
hsync_len: 128,
vsync_len: 4,
sync: FB_SYNC_HOR_HIGH_ACT | FB_SYNC_VERT_HIGH_ACT,
vmode: FB_VMODE_NONINTERLACED
};
This structure is assigned at 2 different places -
savagefb_var = &savagefb_var800x600x8; <------ HERE
...
unsigned char cr6b = VGArCR( 0x6b );
int panelX = (VGArSEQ (0x61) +
((VGArSEQ (0x66) & 0x02) << 7) + 1) * 8;
.....
if (panelX == 800)
savagefb_var = &savagefb_var800x600x8; <----- AND HERE
else if (panelX == 1024)
savagefb_var = &savagefb_var1024x768x8;
else if (panelX == 1280)
savagefb_var = &savagefb_var1280x1024x8;
I suppose one would have to create another structure for 640x480 with
appropriate values? I am afraid to make any modifications since I have no
experience with coding drivers!!
