Since 3.16-rc1 we have this new failure:
When the userspace XOrg ddx schedules vblank events to
trigger deferred kms-pageflips, e.g., via the OML_sync_control
extension call glXSwapBuffersMscOML(), or if a glXSwapBuffers()
is called immediately after completion of a previous swapbuffers
call, e.g., in a tight rendering loop with minimal rendering,
it happens frequently that the pageflip ioctl() is executed
within the same vblank in which a previous kms-pageflip completed,
or - for deferred swaps - always one vblank earlier than requested
by the client app.
This causes premature pageflips and detection of failure by
the ddx, e.g., XOrg log warnings like...
"(WW) RADEON(1): radeon_dri2_flip_event_handler: Pageflip
completion event has impossible msc 201025 < target_msc 201026"
... and error/invalid return values of glXWaitForSbcOML() and
Intel_swap_events extension.
Reason is the new way in which kms-pageflips are programmed
since 3.16.
This commit changes the time window in which the hw can
execute pending programmed pageflips. Before, a pending flip
would get executed anywhere within the vblank interval. Now
a pending flip only gets executed at the leading edge of
vblank (start of front porch), making sure that a invocation
of the pageflip ioctl() within a given vblank interval will
only lead to pageflip completion in the following vblank.
Tested to death on a DCE-4 card.

The hardware lut's only have 256 slots for indexing by a
8 bpc framebuffer. In 10 bpc scanout modes, framebuffer
color values would get truncated to their 8 msb's,
thereby losing the extra precision afforded by a 10 bpc
framebuffer.
To retain full precision, bypass the hw lut in 10 bpc
scanout mode.

Make sure that a hdmi deep color mode can't exceed the max tmds
clock limit of a hdmi sink if such a limit is defined by edid.
If requested deep color bpc would exceed the limit given the mode
to be set, try to degrade gracefully to lower supported deep color
bpc or to standard 8 bpc if needed.

Setting the power state prior to restoring the display

the power state set from dpm resume. The power state
will get set as part of the mode set sequence. Also
add an explicit power state set after mode set resume

The way the tile mode array index was calculated only makes sense for
the CIK specific macrotile mode array. For SI, we need to use one of the
tile mode array indices reserved for displayable surfaces.
This happened to result in correct display most if not all of the time
because most of the SI tiling modes use the same number of banks.

Now that CRTC's have a primary plane, there's no need to track the
framebuffer in the CRTC. Replace all references to the CRTC fb with the
primary plane's fb.
This patch was generated by the Coccinelle semantic patching tool using
the following rules:
@@ struct drm_crtc C; @@
- (C).fb
+ C.primary->fb
@@ struct drm_crtc *C; @@
- (C)->fb
+ C->primary->fb
v3: Generate patch via coccinelle. Actual removal of crtc->fb has been
moved to a subsequent patch.
v2: Fixup several lingering crtc->fb instances that were missed in the
first patch iteration. [Rob Clark]

When drm_helper_disable_unused_functions calls disable
function of the CRTC, it also sets the crtc->fb pointer
to NULL. This can later (when the mode on that CRTC is setup
again from user space) cause ***_do_set_base functions to
"think" that there is no old buffer and skip the unpinning
code. Consequently, the buffer that has been NULL-ified in
drm_helper_disable_unused_functions will never be unpinned
causing a leak in VRAM.
This patch plugs the leak by unpinning the frame buffer
in crtc_disable function.

Since the current KMS API sets the mode independantly on
each crtc, we may end up with resource conflicts. The PLL
allocation is one of those cases. In the following example
we have 3 crtcs in use driving 2 DVI connectors and 1 DP
connector. On the initial kernel modeset for fbdev, the
display topology ends up as follows:
crtc0 -> DP-0
crtc1 -> DVI-0
crtc2 -> DVI-1
Because this is the first modeset, all of the PLLs are
available as none have been assigned. So we end up with
the following:
crtc0 uses DCPLL
crtc1 uses PPLL2
crtc2 uses PPLL1
When X starts, it assigns a different topology:
crtc0 -> DVI-0
crtc1 -> DP-0
crtc2 -> DVI-1
However, since the KMS API is per crtc, we set the mode on each
crtc independantly. When it comes time to set the mode on crtc0,
the topology for crtc1 and crtc2 are still intact. crtc1 and
crtc2 are already assigned PPLL2 and PPLL1 so when it comes time
to set the mode on crtc0, crtc1 and crtc2 have not been torn down
yet, so there appears to be no PLLs available. In reality, we
are reconfiguring the entire display topology, however, since
each crtc is handled independantly, we don't know that in the
driver at each crtc mode set time.
This patch checks to see if the same connector is being driven by
another crtc, and if so, uses the PLL already associated with it.
v2: store connector in the radeon crtc struct, simplify checking.

If several non-DP displays use the same pixel clock
we can use the same PPLL for all of them. If all
relevant displays have the same pixel clock, this
allows the driver to:
- use fewer PPLLs which saves power
- support more than two non-DP displays on DCE4+
The current drm modesetting infrastructure doesn't
really provide a good framework for validating combinations
that work or won't work, so it's possible you could go from
a working configuration to a non-working one by changing the
mode a one of the displays. However, there this is better
than what was there before.

For DP we can use the same PPLL for all active DP

where we may end up sharing a PPLL between DP and
non-DP which won't work. Also clean up the code
a bit.
v2: - fix missing pll_id assignment in crtc init
v3: - fix DP PPLL check
- document functions
- break in main encoder search loop after matching.
no need to keep checking additional encoders.
v4: - same as v3, but re-apply to drm-next as the corner
cases are fixed properly in subsequent patches.
