It seems on some chipsets that doing this from the 0x20 handler causes the
display engine to not ever signal the final 0x40 stage.

This was always really a developer option, and if it's really necessary we

This removes the previous prepare_access() and finish_access() hooks, and
replaces it with a much simpler flush() hook.
All the chipset-specific code before nv50 has its use removed completely,
as it's not required there at all.

Nouveau will no longer load at all if card initialisation fails, so all

The previous handler basically worked correctly for a full-blown mode
change. However, it did nothing at all when a partial (encoder only)
reconfiguation was necessary, leading to the display hanging on certain
types of mode switch.

It turns out that the display engine signals an interrupt for disconnects
too. In order to make it easier to process the display interrupts
correctly, we want to ensure we only get one operation per interrupt
sequence - this is what this commit achieves.

Load detection needs the connector wired to a CRTC, when there are no
inactive CRTCs left that means we need to cut some other head off for
a while, causing intermittent flickering.

Allows us to remove a driver hack that used to be necessary to disable
encoders in certain situations before setting up a mode. The DRM has
better knowledge of when this is needed than the driver does.
This fixes a number of display switching issues.

Uncertain if this is a weirdo configuration, or a BIOS bug. If it's not
a BIOS bug, we still don't know how to make it work anyway so ignore a
"conflicting" DCB entry to prevent a display hang.

As long as we know the length of the opcode, we're probably better off
trying to parse the remainder of an init table rather than aborting in
the middle of it.

Create connectors before encoders to avoid having to do another loop across
encoder list whenever we create a new connector. This allows us to pass
the connector to the encoder creation functions, and avoid using a
create_resources() callback since we can now call it directly.
This can also potentially modify the connector ordering on nv50. On cards
where the DCB connector and encoder tables are in the same order, things
will be unchanged. However, there's some cards where the ordering between
the tables differ, and in one case, leads us to naming the connectors
"wrongly".

register offsets (they're all filled with zeros). Ignore them and use

We just need to clear the SBA and ENABLE bits to reset the AGP
controller: If the AGP bridge was configured to use "fast writes",
clearing the FW bit would break the subsequent MMIO writes and
eventually end with a lockup.
Note that all the BIOSes I've seen do the same as we did (it works for
them because they don't use MMIO), OTOH the blob leaves FW untouched.

* drm-intel-lru:
drm: implement helper functions for scanning lru list
drm_mm: extract check_free_mm_node
drm: sane naming for drm_mm.c
drm: kill dead code in drm_mm.c
drm: kill drm_mm_node->private
drm: use list_for_each_entry in drm_mm.c

These helper functions can be used to efficiently scan lru list
for eviction. Eviction becomes a three stage process:
1. Scanning through the lru list until a suitable hole has been found.
2. Scan backwards to restore drm_mm consistency and find out which
objects fall into the hole.
3. Evict the objects that fall into the hole.
These helper functions don't allocate any memory (at the price of
not allowing any other concurrent operations). Hence this can also be
used for ttm (which does lru scanning under a spinlock).
Evicting objects in this fashion should be more fair than the current
approach by i915 (scan the lru for a object large enough to contain
the new object). It's also more efficient than the current approach used
by ttm (uncoditionally evict objects from the lru until there's enough
free space).
