vga16fb_rectfill

[James S. <jsi...@su...>]

Petr, for some reason I can't get this to work right. Does it look right
to you?

static void vga16fb_fillrect(struct fb_info *info, int x1, int y1,
                             unsigned int width, unsigned int height,
                             unsigned long color, int rop)
{
        int line_ofs = info->fix.line_length - width;
        char *where;
        int x;

        vga_io_wgfx(VGA_GFX_MODE, 0);
        vga_io_wgfx(VGA_GFX_DATA_ROTATE, 0);
        vga_io_wgfx(VGA_GFX_SR_ENABLE, 0xf);
        vga_io_wgfx(VGA_GFX_SR_VALUE, color);
        vga_io_wgfx(VGA_GFX_BIT_MASK, 0xff);

        where = info->screen_base + x1 + y1 * info->fix.line_length;

        while (height--) {
                for (x = 0; x < width; x++) {
                        fb_writeb(0, where);
                        where++;
                }
                where += line_ofs;
        }
        return;
}
