list reservation was too optimistic about ttm object reservation
and could think that an object reserved by some other process
as reserved by the list reservation which was false. Thus when
unreserving the list it might unreserve object that it didn't
reserved in the list. Sorry if it's hard to follow but this
kind of things are just causing headheck.

It appears to be meant to reference the second "default index".
Signed-off-by: NBen Skeggs <bskeggs@redhat.com>

We may not have parsed the entry yet if the i2c_index is for an i2c bus
that's not referenced by a DCB encoder.

This could be done oh so much more nicely, except we have to care about
prehistoric DCB tables too, and they make life painful.

Some handlers don't report specific errors, but we still *really* want to
know if we failed to parse a complete init table.
Signed-off-by: NBen Skeggs <bskeggs@redhat.com>

We really want to be able to distinguish between INIT_DONE and an actual
error sometimes.  This commit fixes up several lazy "return 0;" to be
actual error codes, and explicitly reserves "0" as "success, but stop
parsing this table".

There appears to be some kind of switch on certain chips to control whether
the DP auxch or traditional i2c bus will be operational on a connector,
this commit hopefully fixes nouveau to do the right thing.

Likely only relevent on chips with DP outputs.

The current initialisation code probes 'unsupported' AGP devices
simply by calling its own probe function.  It does not lock these
devices or even check whether another driver is already bound to
them.

We must use the device core to manage this.  So if the specific
device id table didn't match anything and agp_try_unsupported=1,
switch the device id table and call driver_attach() again.

This patch is a combination of the previous two profile
patches, but without the index bugs.  It cleans up and
fixes some issues with pm profile setup on r6xx chips.
Some tables have different orderings for the power states,
also, r600 only has 1 clock mode per power state. On
desktop cards there are no battery modes, so the low and high
power states are the same.  For the low profile case, choose
the lower clock mode.

- Separate dynpm and profile based power management methods.  You can select the pm method
  by echoing the selected method ("dynpm" or "profile") to power_method in sysfs.
- Expose basic 4 profile in profile method
  "default" - default clocks
  "auto" - select between low and high based on ac/dc state
  "low" - DC, low power mode
  "high" - AC, performance mode
  The current base profile is "default", but it should switched to "auto" once we've tested
  on more systems.  Switching the state is a matter of echoing the requested profile to
  power_profile in sysfs.  The lowest power states are selected automatically when dpms turns
  the monitors off in all states but default.
- Remove dynamic fence-based reclocking for the moment.  We can revisit this later once we
  have basic pm in.
- Move pm init/fini to modesetting path.  pm is tightly coupled with display state.  Make sure
  display side is initialized before pm.
- Add pm suspend/resume functions to make sure pm state is properly reinitialized on resume.
- Remove dynpm module option.  It's now selectable via sysfs.
