drm/tegra: Changes for v3.15-rc1
Implement eDP support for Tegra124 and support the PRIME vmap()/vunmap()
operations.
A symbol that is required for upcoming V4L2 support is now exported by
the host1x driver.
Relicense drivers under the GPL v2 for consistency. One exception is the
public header file, which is relicensed under MIT to abide by the common
rule.

Pull request of 2014-04-04
The second vmwgfx pull request for the 3.15 merge window.
Contains a fbdev fix by Christopher Friedt, one fix for a locking order
violation introduced in 3.14 (hit when using queries) and finally a
removal of the DRM_AUTH requirement around some vmwgfx IOCTLS where the
caller is already required to have an open handle to the object.

The GEM CMA helpers uses a custom mmap implementation based on
remap_pfn_range(). While this works when the buffer DMA and physical
addresses are identical, it fails to take IOMMU into account and tries
to mmap the buffer to userspace using the DMA virtual address instead of
the physical address. This results in mapping random physical pages when
the device is behind an IOMMU.
Use the DMA mapping dma_mmap_writecombine() function instead.

Currently drm_pick_cmdline_mode() doesn't care about the interlace
when the given mode line has no "i" suffix. That is, when there are
multiple entries for the same resolution, an interlace mode might be
picked up just depending on the assigned order, and there is no way to
exclude it.
This patch changes the logic for the mode selection, to prefer the
noninterlace mode unless the interlace mode is explicitly given.
When no matching mode is found, it still tries the interlace mode as
fallback.

This decreases eviction by up to 20%, by improving the fragmentation
quality. No harm in normal cases that fit VRAM fully (PTS gaming suite).
In some cases, even the VRAM-fitting cases improved slightly (openarena, urban terror).
512kb was measured as the most optimal threshold for 3d workloads common to radeon.
Other drivers may need different thresholds according to their workloads.

Clients like i915 need to segregate cache domains within the GTT which
can lead to small amounts of fragmentation. By allocating the uncached
buffers from the bottom and the cacheable buffers from the top, we can
reduce the amount of wasted space and also optimize allocation of the
mappable portion of the GTT to only those buffers that require CPU
access through the GTT.
For other drivers, allocating small bos from one end and large ones
from the other helps improve the quality of fragmentation.
Based on drm_mm work by Chris Wilson.

This is the equivalent change in the crtc helpers as done to the i915

drm/i915: don't disable disconnected outputs
This was originally introduced to make encoder sharing on radone
easier for userspace, but:
- It is policy and as such belongs into userspace. E.g. personally I'm
fairly annoyed that a flaky cable results in permanent changes of
the desktop layout, so I'll kick out DEs which do this. Worse if the
kernel also tries to be clever.
- It's inconsistent: We only kill disconnected outputs on setCrtc
(which userspace might also call when just changing the
framebuffer), but not when e.g. we receive a hpd event or in the
output poll worker.
- It's unexpected behaviour for the userspace driver, at least in the
intel ddx we've had tons of bugs where the driver fell over and
killed the X session becuase pageflips/vblanks suddenly stopped
working. We've had to fix this by wrapping every single setCrtc int
a big "recover kms state from the kernel again" operation.
- It's suprising for the kernel, too: It took a few mails between Rob,
Matt and me for them to notice that little dragon wreaking havoc
with the universal plane framebuffer refcounting.
- Userspace can cope with it and e.g. Gnome already kills disconnected
outputs and reconfigures the desktop automatically. And since there
have been no regression reports for the i915 change from over 1 year
ago I think all other DEs are also ready.
