The hardware team suggest that the "large buffer" method should be
used to calculate the cursor watermark under non-SR state as well,
which is to avoid the flicker when FBC is enabled on Ironlake.

The total self-refresh fifo entry size for display plane is 512
instead of 128 for 965G. Also fix WM value mask for 965G.
About 1.0W power can be saved on one T61 laptop after the self-refresh

For self-refresh mode WM calculation's "line time" should use
mode's htotal instead of hdisplay. "surface width" is the hdisplay
for display plane and 64 for cursor plane.

Should be:

else if (mode0)

Otherwise we may end up calculating the priority regs with

This interface allows userspace to request hyperz support, it probably
needs more locking, and really reporting that you can have hyperz is racy
since someone else might get it before you do.

also fixed incorrect 0x4f1c reference.
v3: fixup zb_bw_cntl so older drivers keep working
v4: add locking, fixup SC_HYPERZ_EN - patch stream to disable hiz

BIOS scripts usually make an attempt to reset the AGP controller,
however on some nv4x cards doing it properly involves switching FW off
and on: if we do that without updating the AGP bridge settings
accordingly (e.g. with the corresponding calls to agp_enable()) we
will be locking ourselves out of the card MMIO space. Do it from
nouveau_mem_reset_agp() before the init scripts are executed.

Rescaling interlaced modes isn't going to work correctly, and even if
it did, come on, interlaced flat panels? are you pulling my leg?

It doesn't like variable length arrays.

A previous commit started additionally using the SOR link when trying to
match the correct output script. However, we never fill in this field
for LVDS so we can never match a script at all.

There's a report of this quirk breaking modesetting on at least one board.
After discussion with Francisco Jerez, we've decided to remove it:
<darktama> it's not worth limiting the quirk to just where we know it can
work? i'm happy either way really :)
<curro> hmm, don't think so, most if not all DCB15 cards have just one DAC
<curro> and with that quirk there's no way to tell if the load comes from
the VGA or DVI port
