What the ^*!#^% is this:
driver/video/pvr2fb.c:
int __init pvr2fb_init(void)
{
struct fb_var_screeninfo var;
u_long modememused;
if (!MACH_DREAMCAST)
return -ENXIO;
...
That's the first time I've seen such, well, badness.
It looks like someone forgot what platform is *required* for the PowerVR 2...
drivers/video/Config.in:
tristate ' NEC PowerVR 2 display support' CONFIG_FB_PVR2
dep_bool ' Debug pvr2fb' CONFIG_FB_PVR2_DEBUG $CONFIG_FB_PVR2

PS: Compiling 2.4.9 on an Alpha is turning up all manner of weird stuff. Like
a lot of drivers that aren't 64bit clean, missing parts of asm-alpha...

Linus should have the main missing bits of asm-alpha in 2.4.10pre - although
on x86 that crashes rapidly for me.

No one said mine was bootable either :-) It builds. Booting has yet to be
tested (must fix dinner first.)
The things I go through for my "neat toys" (firewire on an alpha) On a side
note, the Alpha BIOS Emulation (tm) isn't exactly perfect... the Mylex RAID
configuration stuff won't run -- I know I'm asking alot *grin* I'll try it
with the DPT (I20) controller in a while. (It ain't easy putting cards in
my alpha. I've bled on it a few times in the process already.)

The pvr2fb driver is named as such because eventually we want to be able to
support all CLX boards, not just the chip found in the Dreamcast. Right
now it only supports the Dreamcast and only builds under LinuxSH - vanilla
kernels can't be targetted to the DC.
The main problem with writing this driver is that not only are the specs
from VideoLogic impossible to obtain w/out signing an NDA, the only
commodity pvr2 board that you can find (others have looked) is the
Dreamcast. I have Win32 pvr2 drivers to play with, but it's kinda useless
if I don't have a board to test.
