Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000009
It has helped me to add a NULL pointer check that was suggested at
http://lists.freedesktop.org/archives/dri-devel/2014-October/070663.html
I am not familiar with the code. But the change looks sane
and we need something fast at this stage of 3.18 development.

On boards with a high default fan speed this should

If ddc fails, presumably the i2c mux (and hopefully the signal
mux) are switched to the other GPU so don't fetch the edid from
the vbios so that the connector reports disconnected.

Some radeon ASICs don't support all 64 address bits of MSIs despite
advertising support for 64-bit MSIs in their configuration space.
This breaks on systems such as IBM POWER7/8, where 64-bit MSIs can
be assigned with some of the high address bits set.
This makes use of the newly introduced "no_64bit_msi" flag in structure
pci_dev to allow the MSI allocation code to fallback to 32-bit MSIs
on those adapters.

Just use the acpi interface. That's what windows uses on this

You can still force the native backlight interface by setting

While developing MST support I noticed I often got the wrong data

The power management code calls into the display code for
certain things. If certain power management sysfs attributes
are called before the driver has finished initializing all of
the hardware we can run into problems with uninitialized
modesetting state. Add a check to make sure modesetting
init has completed to the bandwidth update callbacks to
fix this. Can be triggered by the tlp and laptop start
up scripts depending on the timing.

This way the necessary VM update is kicked off immediately
if all BOs involved are in GPU accessible memory.
v2: fix vm lock
v3: immediately update unmaps as well
v4: use drm_free_large instead of kfree

Only invalidating PTEs needs to be executed synchronized to using the PT.

We never invalidate PD entries and making them valid can
run with other users in parallel.

This allows us to finally remove the VM fence and
so allow concurrent use of it from different engines.

Use multiple VMIDs for each VM, one for each ring. That allows
us to execute flushes separately on each ring, still not ideal
cause in a lot of cases rings can share IDs.

Note for each fence if it's a VM page table update or not. This allows
us to determine the last VM update in a sync object and so to figure
out if we need to flush the TLB or not.

Previously we just allocated space for four hardware semaphores
in each software semaphore object. Make software semaphore objects
represent only one hardware semaphore address again by splitting
the sync code into it's own object.

That's useless when all callers drop the reservation
immediately after calling the function.

The current code always reprogrammed the sclk levels,
but we don't currently handle disp sclk requirements
so just skip it.

Enable smc fan control for CI boards. Should
reduce the fan noise on systems with a higher
default fan profile.
v2: disable by default, add additional fan setup, rpm control
