On device to host data using msgbuf the read pointer gets updated
once all data is processed. Updating this pointer more frequently
allows the firmware to add more data quicker. This will result in
slightly higher and more stable throughput on CPU bounded host
processors.

Currently we're forgetting to double the port clock when using double
clocked modes with 12bpc on HDMI. We're only accounting for the 1.5x
factor due to the 12bpc. So further double the 1.5x port clock when we
have a double clocked mode.
Unfortunately I don't have any displays that support both 12bpc and
double clocked modes, so I was unable to test this.

Check that the DIP is enabled on the right port on IBX and VLV/CHV as
we're doing on g4x, and also check for all the infoframe enable bits on
all platforms.
Eventually we should track each infoframe type independently, and also
their contents. This is a small step in that direction as .infoframe_enabled()
return value could be easily turned into a bitmask.

Currently we just disable the GCP infoframe when turning off the port.
That means if the same transcoder is used on a DP port next, we might
end up pushing infoframes over DP, which isn't intended. Just disable
all the infoframes when turning off the port.
Also protect against two ports stomping on each other on g4x due to
the single video DIP instance. Now only the first port to enable
gets to send infoframes.

Follow the procedure listed in Bspec to toggle the port enable bit off
and on when enabling HDMI with 12bpc and pixel repeat on IBX. The old
code didn't actually enable the port before "toggling" the bit back off,
so the whole workaround was essentially a nop.
Also take the opportunity to clarify the code by splitting the gmch
platforms to a separate (much more straightforward) function.

GCP infoframes are required to inform the HDMI sink about the color
depth.
Send the GCP infoframe whenever the sink supports any deep color modes
since such sinks must anyway be capable of receiving them. For sinks
that don't support deep color let's skip the GCP in case it might
confuse the sink, although HDMI 1.4 spec does say all sinks must be
capable of reciving them. In theory we could skip the GCP infoframe
for deep color sinks in 8bpc mode as well since sinks must fall back to
8bpc whenever GCP isn't received for some time.
BSpec says we should disable GCP after disabling the port, so do that as
well.

With the introduction of multiple views of an obj in the same vm, each
vma was taught to cache its copy of the pages (so that different views
could have different page arrangements). However, this missed decoupling
those vma->ggtt_view.pages when the vma released its reference on the
obj->pages. As we don't always free the vma, this leads to a possible
scenario (e.g. execbuffer interrupted by the shrinker) where the vma
points to a stale obj->pages, and explodes.
Fixes regression from commit fe14d5f4e5
Author: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
Date: Wed Dec 10 17:27:58 2014 +0000
drm/i915: Infrastructure for supporting different GGTT views per object
Tvrtko says, if someone else will be confused how this can happen, key
is the reservation execbuffer path. That puts the VMA on the exec_list
which prevents i915_vma_unbind and i915_gem_vma_destroy from fully
destroying the VMA. So the VMA is left existing as an empty object in
the list - unbound and disassociated with the backing store. Kind of a
cached memory object. And then re-using it needs to clear the cached
pages pointer which is fixed above.

Currently existing dio workers can jump in and potentially increase
extent tree depth while we're allocating blocks in
ext4_alloc_file_blocks(). This may cause us to underestimate the
number of credits needed for the transaction because the extent tree
depth can change after our estimation.
Fix this by waiting for all the existing dio workers in the same way
as we do it in ext4_punch_hole. We've seen errors caused by this in
xfstest generic/299, however it's really hard to reproduce.

Currently in ext4_alloc_file_blocks() the number of credits is
calculated only once before we enter the allocation loop. However within
the allocation loop the extent tree depth can change, hence the number
of credits needed can increase potentially exceeding the number of credits
reserved in the handle which can cause journal failures.
Fix this by recalculating number of credits when the inode depth
changes. Note that even though ext4_alloc_file_blocks() is only
currently used by extent base inodes we will avoid recalculating number
of credits unnecessarily in the case of indirect based inodes.
