if you use this patch below diff --git a/drivers/video/mb862xx/mb862xxfb.c b/drivers/video/mb862xx/mb862xxfb.c index 26b66cb..904a111 100644 --- a/drivers/video/mb862xx/mb862xxfb.c +++ b/drivers/video/mb862xx/mb862xxfb.c @@ -218,6 +218,8 @@ static int mb862xxfb_set_par(struct fb_info *fbi) if (par->pre_init) return 0; + fbi->fix.line_length = (fbi->var.xres_virtual * + fbi->var.bits_per_pixel) / 8; /* disp off */ reg = inreg(disp, GC_DCM1); reg &= ~GC_DCM01_DEN; and something like this in user space: int fd; struct fb_var_screeninfo var_info; if ((fd=open("/dev/fb0", O_RDWR))==-1) { fprintf(stderr, "Cannot open /dev/fb0\n"); exit(1); } var_info.xres = 800; var_info.yres = 600; var_info.xres_virtual = 800; var_info.yres_virtual = 600; var_info.pixclock = 25000; var_info.left_margin = 88; var_info.right_margin = 40; var_info.lower_margin = 1; var_info.upper_margin = 23; var_info.hsync_len = 128; var_info.vsync_len = 4; if (ioctl(fd, FBIOPUT_VSCREENINFO, &var_info)<0) { fprintf(stderr, "Cannot set fb var_info\n"); exit(1); } than 800x600 resolution should be possible too. Also 1024x768 resolution should be possible with appropriate parameters. > BTW, I tried this patch and I get wrong colors on a patched DirectFB > which is changing the endianness on the fly.

But to get proper framebuffer console colors with carmine/coralp GDCs I used a small patch below: diff --git a/include/linux/fb.h b/include/linux/fb.h index ae4ecdf..e998048 100644 --- a/include/linux/fb.h +++ b/include/linux/fb.h @@ -891,11 +891,11 @@ struct fb_info { #define fb_readb __raw_readb #define fb_readw __raw_readw -#define fb_readl __raw_readl +#define fb_readl readl #define fb_readq __raw_readq #define fb_writeb __raw_writeb #define fb_writew __raw_writew -#define fb_writel __raw_writel +#define fb_writel writel #define fb_writeq __raw_writeq #define fb_memset memset_io Best regards, Anatolij -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: +49-8142-66989-0 Fax: +49-8142-66989-80 Email: [EMAIL PROTECTED] _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
