If anyone can come up with an example of a bus where:
- both i/o and memory resources are addressable
- access to them can be controlled
- but they can't be controlled independently
then by all means, reinstate this logic.
No point warning about missing driver hooks, that just means the person
who gave you the driver is inept. Might as well just crash. Also,
just name anonymous screens as screen%d instead of failing after the 36th
screen. Bonus points if you can figure out what the failure mode would
be on the 36th screen, and what the effective screen limit was.
This code was effectively only used in ix86Pci.c to select PCI config
access type. Nobody should be using that path anymore, in the glorious
pciaccess world; kernel services should get it right for you.
the defaults from InitVelocityData() or hypothetic driver-side changes
are now respected, not overridden.

If the device doesn't have any BARs then it's just a stub for some
lame operating systems that need one PCI device per output for
multihead. No point in warning about it.
It's all a bit wonky since both sis(4) and xgi(4) claim to support the
Volari Z7 and V5/8 (0x0020 and 0x0040), so let's side with xgi(4), why
not. Note that the V3 (not V3XT) identifies itself as a trident chip.
Put out a warning if xorg.conf has InputDevice sections, but these aren't
referenced in the used ServerLayout. This is only performed if AllowEmptyInput
is enabled.
The reason behind this is that the server used to auto-add the first
mouse/keyboard sections if none where referenced. Now, with HAL and AEI
enabled by default, setups that relied on this auto-adding break and are left
without input devices. The least we can do is warn them.
- Use a single common function to compute reducedness.
- Call it from both the old-school and new-school mode validation paths.
- Define monitor reduced-blanking support in accord with EDID 1.4.
- Attempt to filter RB DMT modes away from the "standard" EDID pool if
the monitor doesn't claim RB support.
