[Linux-fbdev-devel] fb_info ``disp'' field and multiple fb's

[Emmanuel M. <emm...@re...>]

Hi,

all fb implementations I find so far fill the disp
field:
	fb_info.disp = &disp; /* used during initialization */
with a 
static struct display disp;

and enable only one framebuffer device.

I'm writing code that allows one fb per pci device; and I
have to support multiple ones. Should I extend fb_info like this:

struct moreinfo {
struct fb_info fb;
static struct display disp;
struct pci_dev *pdev;
};

static int vfb_getcolreg(u_int regno, u_int *red, u_int *green, u_int *blue,
                         u_int *transp, struct fb_info *info)
{ 
	struct moreinfo *my=(struct moreinfo *)info;
        ...
}

and set during init:
my->fb.disp=&my->disp;

or is it enough to have one real struct display for all of them?

Seems disp has a dispsw member that has to change on a per fb basis.

Sincerely yours,
