In DP mode, the DP ref clock can come from PPLL, DCPLL, or ext clock,
depending on the asic. The crtc virtual pixel clock is derived from
the DP ref clock.
- DCE4: PPLL or ext clock
- DCE5: DCPLL or ext clock
Setting ATOM_PPLL_INVALID will cause SetPixelClock to skip
PPLL/DCPLL programming and only program the DP DTO for the
crtc virtual pixel clock.

The ddc proxy depends upon the underlying i2c bus being selected. Under
certain configurations, the i2c-adapter functionality is queried during
initialisation and so may trigger an OOPS during boot. Hence, we need to
reorder the initialisation of the ddc proxy until after we hook up the i2c
adapter for the SDVO device.
The condition under which it fails is when the i2c_add_adapter calls
into i2c_detect which will attempt to probe all valid addresses on the
adapter iff there is a pre-existing i2c_driver with the same class as
the freshly added i2c_adapter.
So it appears to depend upon having compiled in (or loaded such a
module before i915.ko) an i2c-driver that likes to futz over the
i2c_adapters claiming DDC support.

On g4x, user interrupt in BSD ring is missed.
This is because though g4x and ironlake share the same bsd_ring,
their interrupt control interfaces have _two_ differences.
1.different irq enable/disable functions:
On g4x are i915_enable_irq and i915_disable_irq.
On ironlake are ironlake_enable_irq and ironlake_disable_irq.
2.different irq flag:
On g4x user interrupt flag in BSD ring on is I915_BSD_USER_INTERRUPT.
On ironlake is GT_BSD_USER_INTERRUPT
Old bsd_ring_get/put_irq call ring_get_irq and ring_get_irq.
ring_get_irq and ring_put_irq only call ironlake_enable/disable_irq.
So comes the irq miss on g4x.
To fix this, as other rings' code do, conditionally call different
functions(i915_enable/disable_irq and ironlake_enable/disable_irq)
and use different interrupt flags in bsd_ring_get/put_irq.

When xorg state tracker wants to hide the cursor it calls set_cursor
with NULL buffer_handle and size=0x0, but nouveau refuses to hide it
because size is not 64x64... which is a bit odd. Both radeon and intel
check buffer_handle before validating size of cursor, so make nouveau
implementation consistent with them.

The core/mem/shader clocks don't support the fractional feedback divider,
causing our calculated clocks to be off by quite a lot in some cases. To
solve this we will switch to a search-based algorithm when fN is NULL.
For my NVA8 at PL3, this actually generates identical cooefficients to
the binary driver. Hopefully that's a good sign, and that does not
break VPLL calculation for someone..

Hopefully this is how we're supposed to correctly handle when the RAMCFG
strap is above the number of entries in timing-related tables.
It's rather difficult to confirm without finding a configuration where
the ram restrict table doesn't map 8-15 back onto 0-7 anyway. There's
not a single vbios in the repo which is configured differently..
In any case, this is probably still better than potentially reading
outside of the bounds of various tables..
