Linux 3.16's radeon-kms introduced 10 bpc fb support.
Currently, as of X-Server 1.19, this works with exa accel,
but not yet when using glamor acceleration.
v2: Style fixes, check for glamor first, as suggested
by Michel.

Option "TearFree" now sets the default value of the output property.
See the manpage update for details.
TearFree is now enabled by default for outputs using rotation or other
RandR transforms, and for RandR 1.4 slave outputs.

glamor should now perform at least as well as EXA in general, and this
allows DRI3 to be enabled by default for >= R600.

This means that all possible paths can be handled as intended, no matter
which Xorg version the driver happened to be compiled against.

Add Option "DRI" to allow selection of maximum DRI level.
This allows the user to select the maximum level of DRI
implementation to use, DRI2 or DRI3. It replaces the old
option "DRI3" which had exactly the same purpose, but
differs from the method used in both intel ddx and nouveau ddx.
Make this consistent before a new stable driver is released.
v2: Retain handling of old Option "DRI3" for backwards
compatibility, but Option "DRI" will take precedence
over "DRI3" if both are provided.

Avoids tearing by flipping between two scanout BOs per (non-rotated) CRTC
v2:
* Fix condition for TearFree log message (Richard Wilbur)
* Log warning message about DRI page flipping being enabled because of
TearFree (or ShadowPrimary) also when building without glamor support
v3:
* Only override fb_id/x/y if all scanout pixmaps have been successfully
allocated
v4:
* Make log warning clearer if drmModePageFlip returns an error
Reviewed-by: Alex Deucher <alexander.deucher@amd.com> (v1)
When this option is enabled, most pixmaps (including the screen pixmap)
are allocated in system RAM and mostly accessed by the CPU. Changed areas
of the screen pixmap are copied to dedicated per-CRTC scanout pixmaps
regularly, triggered by the vblank interrupt.
v2:
* Set region data pointer to NULL for keeping only the extents
* Move pRegion and pBox local variable declarations closer to their uses
in drmmode_set_mode_major()
Only if the kernel has the new CP firmware.
v2: check value of ACCEL_WORKING2
v3 (Andreas Boll):
- check for value 2 or 3 of ACCEL_WORKING2
- update man page

Removes the need for a double negation when forcing acceleration on.
Note that this change is backwards compatible, as the option parser
automagically handles the 'No' prefix.

Now that mesa 9.2 is out with support for tiling
