vga16fb is an available config option on powerpc, but it won't link
with my .config:
ERROR: "vgacon_remap_base" [drivers/video/vga16fb.ko] undefined!
I'm guessing this is because include/asm-powerpc/vga.h declares
vgacon_remap_base:
extern unsigned long vgacon_remap_base;
...but arch/powerpc/kernel/setup_32.c wraps the definition in an #ifdef:
#ifdef CONFIG_VGA_CONSOLE
unsigned long vgacon_remap_base;
EXPORT_SYMBOL(vgacon_remap_base);
#endif
So CONFIG_VGA_CONSOLE=n and CONFIG_FB_VGA16=[y|m] won't work.
I've also noticed that the only places in the tree that ever assign
anything to config_remap_base are under arch/ppc. And
include/asm-powerpc/vga.h also does this:
#ifdef __powerpc64__
#define VGA_MAP_MEM(x,s) ((unsigned long) ioremap((x), s))
#else
#define VGA_MAP_MEM(x,s) (x + vgacon_remap_base)
#endif
So VGACON probably doesn't work either on 32bit. I'm guessing arch/powerpc
doesn't support PREP.
How best could this be fixed up? Or should I just let the thing
be? This is obviously not a new thing, and I don't have any hardware
that supports this stuff either.
