These parameters are the same for all currently known VIA IGPs so it
does not make any sense to store them with IGP specific data. This
saves a few bytes and helps a bit in dicovering the real differences.

This patch removes some write-only variables from the device management
structures. Just a small cleanup.

This patch removes all internal uses of another mostly artificial
value. It does duplicate the information of the maximum resolution and
it is not flexible as only a few resolutions exist. Hence it is better
to remove it and clean the mess up.
No runtime change expected.

This driver is not respecting the iomem memory space restrictions
and does direct access. This works on x86 but is non-portable and
should not be done. Converted memcpy() of 2 to readw.
Last post increment of romptr was unnecessary since pointer never
used after that.
Found by sparse, compile tested only.

This patch removes an assignment to the deprecated i2c_adapter.id
field. Since the field isn't used anywhere else in the driver it is
save to remove it.

Supports YCbCr420sp, YCbCr422sp, and YCbCr44sp, formats
(bpp = 12, 16, and 24) respectively.
When double-buffering both Y planes appear before the C planes (Y-Y-C-C),
as opposed to Y-C-Y-C.
Set .nonstd in struct sh_mobile_lcdc_chan_cfg to enable YUV mode, and use
.bpp to distiguish between the 3 modes.
The value of .nonstd is copied to bits 16-31 of LDDFR in the LCDC and
should be set accordingly.
.nonstd must be set to 0 for RGB mode.
Due to the encoding of YUV data, the framebuffer will clear to green
instead of black.
In YUV 420 mode, panning is only possible in 2 line increments.
Additionally in YUV 420 mode the vertical resolution of the framebuffer
must be an even number.

This commit changed an internal radeon structure, that meant a new driver
in -next had to be fixed up, merge in the commit and fix up the driver.
Also fixes a trivial nouveau merge.

Usually EDID retrieval is fine. However, sometimes, especially when the
machine is loaded, it fails, but succeeds after a few retries.

As detect will use hw registers and may modify structures, it needs to be
serialised by use of the dev->mode_config.mutex. Make it so.
Otherwise, we may cause random crashes as the sysfs file is queried
whilst a concurrent hotplug poll is being run. For example:

Commit 21e86c1c8a844bf978f8fc431a59c9f5a578812d ("drm/nouveau: remove
cpu_writers lock") turned on lazy waits. Unfortunately
__nouveau_fence_wait was not optimized for this case and on HZ=100
kernel wasted up to 10 ms per call.
Depending on application, it led to 10-30% FPS regression.
Fix it.

now have a ramin_rsvd_vram larger than 2MiB anyway.

At least on my HP 2540p this is wrong at bootup, fine
at any other time once a lid event has occured. This is due to
_REG vs _INI ordering in the ACPI tables.

Some hardware claims to have both an LVDS panel and an eDP output.
Whilst this may be true in a rare case, more often it is just broken
hardware. If we see an eDP device we know that it must be connected and
so we can confirm its existence with a simple probe.

I stumbled over this magic bit in the gen3 INSTPM:
Bit11 Interrupt-Based AGPBUSY# Enable:
‘0’ = Pending GMCH interrupts will not cause AGPBUSY# assertion.
‘1’ = Pending GMCH interrupts will cause AGPBUSY# assertion and hence
can cause the CPU to exit C3. There is no suppression of cacheable
writes.
Note that in either case in C3 the interrupts are not lost. They will be
forwarded to the ICH when the GMCH is out of C3.

Using PM latency request turns out to be very fragile and only works for
some systems, depending upon the ACPI implementation. However, I've
stumbled across a promising bit in INSTPM: "Interrupt-Based AGPBUSY#".

Userspace has a legitimate requirement to use a delta that points to

abi break, albeit a relaxation of the current restrictions, mark the change

The code paths for modesetting are growing in complexity as we may need
to move the buffers around in order to fit the scanout in the aperture.
Therefore we face a choice as to whether to thread the interruptible status
through the entire pinning and unbinding code paths or to add a flag to
the device when we may not be interrupted by a signal. This does the
latter and so fixes a few instances of modesetting failures under stress.

As we just need a temporary array whilst performing the relocations for
the execbuffer, first attempt to allocate using kmalloc even if it is
not of order page-0. This avoids the overhead of remapping the
discontiguous array and so gives a moderate boost to execution
throughput.

Dave Airlie spotted that we had a potential bug should we ever rearrange
the drm_i915_gem_object so not the base drm_gem_object was not its first
member. He noticed that we often convert the return of
drm_gem_object_lookup() immediately into drm_i915_gem_object and then
check the result for nullity. This is only valid when the base object is
the first member and so the superobject has the same address. Play safe
instead and use the compiler to convert back to the original return
address for sanity testing.

In a few places I replaced reads of per-pipe registers with the actual
register offsets themselves (converting I915_READ(reg) to _PIPE(reg)).
Alexey caught this on his 9xx machine because the cursor control write
was affected. A quick audit showed a few more places where I'd borked
a read, so here's a patch to fix things up.

attempted fix dcbe6f2b3d136995915e2f9ecc7d4f3b28f47b6c.
There is a single clock source used for both SSC (some LVDS and DP) and
non-SSC (VGA, DVI) outputs. So we need to be careful to only enable SSC
as necessary. However, fiddling with DREFCLK was causing DP links to be
dropped and we do not have a fix ready, so revert.

We can enable some safely, but FDI and transcoder interrupts can occur
and block other interrupts from being detected (like port hotplug
events). So keep them disabled by default (they can be re-enabled for
debugging display bringup, but should generally be off).
