Isn't that why CONFIG_EARLY_PRINTK was written? (And I mentioned Linus's hack
using the RTC to see how far the _really_ early stuff got.)
Don't think that works with frame buffers.
Earlier I was trying to distinguish between /dev/console (no controlling tty),
virtual terminals (tied to old VGA hardware although possibly usable through
the framebuffer, I'm unclear on this), the tty layer (which is what I
initially thought the patch was aimed at, but it seems to be the vga VT
stuff), and having a bitmapped display (may be GUI only). Four separate
things, I've lost track of which we're talking about here.
When you imply it's stupid to think anyone will ever have a console on an
embedded system (because we all know the embedded world is far more uniform
than crazy diverse things like the desktop space), which of these are _you_
referring to?
I'm talking about the virtual console stuff, which is *not* inherently
tied to VGA.
The issue is whether it makes sense to have virtual console capability
on a device which is so constrained that you want a *subset* of the
functionality in place.
