Rather than building a config which may or may not work, let the driver
build an initial fb config. This allows the driver to use the BIOS boot
configuration for example, displaying kernel messages and the initial fb
console on the same outputs the BIOS lit up at boot time. If that
fails, the driver can still fall back the same way as the core.

There is a minute window for a race between put-fence removing the fence

we must zap the mmap prior to removing the fence and not afterwards.

In the case where the hardware has been wrongly programmed and the EDP
TRANS_DDI_FUNC_CTL register has a bogus value in its EDP Input field, we
were using the pipe variable uninitialized.
In this case, shutdown the transcoder. It will be programmed correctly
the next time we try to enabled eDP.
Note from Paulo's review: Wrong modeset sequence can easily lead to
frozen machines hence the disable_ddi call might be risky. But since
things are awry already, doesn't matter too much.

QXL is a paravirtual graphics device used by the Spice virtual desktop
interface.
The drivers uses GEM and TTM to manage memory, the qxl hw fencing however
is quite different than normal TTM expects, we have to keep track of a number
of non-linear fence ids per bo that we need to have released by the hardware.
The releases are freed from a workqueue that wakes up and processes the
release ring.
releases are suballocated from a BO, there are 3 release categories, drawables,
surfaces and cursor cmds. The hw also has 3 rings for commands, cursor and release handling.
The hardware also have a surface id tracking mechnaism and the driver encapsulates it completely inside the kernel, userspace never sees the actual hw surface
ids.
This requires a newer version of the QXL userspace driver, so shouldn't be
enabled until that has been placed into your distro of choice.

- gen2-4 vblank fixes from Ville.
- Unclaimed register warning fixes for hsw (Paulo). More still to come ...
- Complete pageflips which have been stuck in a gpu hang, should prevent

Change the gen6+ max delay if the pcode read was successful (not the
inverse).
The previous code was all sorts of wrong and has existed since I broke
it:
commit 42c0526c930523425ff6edc95b7235ce7ab9308d
Author: Ben Widawsky <ben@bwidawsk.net>
Date: Wed Sep 26 10:34:00 2012 -0700
drm/i915: Extract PCU communication
I added some parentheses for clarity, and I also corrected the debug
message message to use the mask (wrong before I came along) and added a
print to show the value we're changing from.
Looking over the code, I'm not actually sure what we're trying to do. I
introduced the bug simply by extracting the function not implementing
anything new. We already set max_delay based on the capabilities
register (which is what we use elsewhere to determine min and max).
This would potentially increase it, I suppose? Jesse, I can't find the
document which explains the definitions of the pcode commands, maybe you
have it around.
Based on Jesse's response, this could potentially be for -fixes, or
stable, or maybe lead to us dropping it entirely. As the current code is
is, things won't completely break because of the aforementioned
capabilities register, and in my experimentation, enabling this has no
effect, it goes from 1100->1100.
I found this while reviewing Jesse's VLV patches.

The index variable points at a page table, not a page directory or a
pde. Ben Widawsky fix this up correctly in his ppgtt cleanup, but I've
botched the job and copy&pasted the old confusion from the original
gen6 ppgtt code in

v2: use FORCEWAKE_KERNEL (Ville)
Note: Ville mentioned in his review that he declines to be responsible
if this blows up due to the lack of "readback a register != FW_ACK,

It fixes the issue arises due to passing 'nr_pages' in place of 'nents' to
sg_alloc_table. When ARM_HAS_SG_CHAIN is disabled, it is causing failure in
creating SG table for the buffers having more than 204 physical pages i.e.
equal to SG_MAX_SINGLE_ALLOC.
When using sg_alloc_table_from_pages interface, in place of sg_alloc_table,
page list will be passes to get each contiguous section which is represented
by a single entry in the table. For a Contiguous Buffer, number of entries
should be equal to 1.
Following check is causing the failure which is not applicable for Non-Contig
buffers:
if (WARN_ON_ONCE(nents > max_ents))
return -EINVAL;
Above patch is well tested for EXYNOS4 and EXYNOS5 for with/wihtout IOMMU
supprot. NOUVEAU and RADEON platforms also depends on drm_prime_pages_to_sg
helper function.

The existing gtt setup code is correct - and so doesn't need to be fixed to
handle compact dma scatter lists similarly to the previous patches. Still,
take the for_each_sg_page macro into use, to get somewhat simpler code.

So far we created a sparse dma scatter list for gem objects, where each
scatter list entry represented only a single page. In the future we'll
have to handle compact scatter lists too where each entry can consist of
multiple pages, for example for objects imported through PRIME.
The previous patches have already fixed up all other places where the
i915 driver _walked_ these lists. Here we have the corresponding fix to
_create_ compact lists. It's not a performance or memory footprint
improvement, but it helps to better exercise the new logic.

So far the assumption was that each dma scatter list entry contains only
a single page. This might not hold in the future, when we'll introduce
compact scatter lists, so prepare for this everywhere in the i915 code
where we walk such a list.
We'll fix the place _creating_ these lists separately in the next patch
to help the reviewing/bisectability.

This is needed since currently sg_for_each_page assumes that we have
a valid page in each sg item. It is only a real problem for
CONFIG_SPARSEMEM where the page is dereferenced, in other cases the
iterator works ok with an invalid page pointer.
We can remove this workaround when we have fixed sg_page_iter to work on
scatterlists without backing pages.
