d7ccd8fc11 drm/radeon/kms: add drm blit support for evergreen
This patch implements blit support for bo moves using
the 3D engine.  It uses the same method as r6xx/r7xx:
- store the base state in an IB
- emit variable state and vertex buffers to do the blit

This allows the hw to move bos using the 3D engine and allows
full use of vram beyond the pci aperture size.

75fa0b08e5 drm/radeon: Modify radeon_pm_in_vbl to use radeon_get_crtc_scanoutpos()
radeon_pm_in_vbl() didn't report in vblank status accurately. Make
it a wrapper around radeon_get_crtc_scanoutpos() which corrects for
biases, so it reports accurately.

radeon_pm_in_vbl() will only report in_vbl if all active crtc's
are currently inside vblank.

agd5f: use rdev->num_crtc rather than hardcoding the crtc count

6383cf7d78 drm/radeon: Add function for display scanout position query.
radeon_get_crtc_scanoutpos() returns the current horizontal
and vertical scanout position of a crtc. It also reports if
the display scanout is currently inside the vblank area.

hpos reports current horizontal pixel scanout position.
vpos reports the current scanned out line as a value >= 0
in active scanout. If the scanout is inside vblank area, it
reports a negative value, the number of scanlines until
end of vblank aka start of active scanout, e.g., -3 ==
"At most 3 scanlines until end of vblank".

This code is derived from radeon_pm_in_vbl(), tested on
R500 and R600.

ba032a58d1 drm/radeon/kms: rework spread spectrum handling
This patch reworks spread spectrum handling to enable it
properly on lvds and DP/eDP links.  It also fixes several
bugs in the old spread spectrum code.

- Use the ss recommended reference divider if available
when calculating the pll
- Use the proper ss command tables on pre-DCE3 asics
- Avoid reading past the end of the ss info tables
- Enable ss on evergreen asics (lvds, dp, tmds)
- Enable ss on DP/eDP links

48dfaaeb66 drm/radeon/kms: remove new pll algo
The recent changes to the old algo (prefer high post div)
coupled with the range and precision limitations of using
fixed point with the new algo make the new algo less
useful.  So drop the new algo.  This should work as well
or better than the old new/old combinations and simplifies
the code a lot.

5bccf5e32f drm/radeon: add properties to configure the width of the underscan borders
This allows for a more exact fitting on the physical
display. The new properties default to zero which corresponds to the
previous underscan border width[height] formula:
(display_width[display_width] >> 5) + 16.

Example to set a horizontal border width of 30 and a vertikal border
height of 22:

   xrandr --output HDMI-0 --set underscan on --set "underscan hborder" 30 --set "underscan vborder" 22

d0f8a854c3 drm/radeon/kms/r6xx+: use new style fencing (v3)
On r6xx+ a newer fence mechanism was implemented to replace
the old wait_until plus scratch regs setup.  A single EOP event
will flush the destination caches, write a fence value, and generate
an interrupt.  This is the recommended fence mechanism on r6xx+ asics.

This requires my previous writeback patch.

v2: fix typo that enabled event fence checking on all asics
rather than just r6xx+.

v3: properly enable EOP interrupts
Should fix:

724c80e1d6 drm/radeon/kms: enable writeback (v2)
When writeback is enabled, the GPU shadows writes to certain
registers into a buffer in memory.  The driver can then read
the values from the shadow rather than reading back from the
register across the bus.  Writeback can be disabled by setting
the no_wb module param to 1.

On r6xx/r7xx/evergreen, the following registers are shadowed:
- CP scratch registers
- CP read pointer
- IH write pointer
On r1xx-rr5xx, the following registers are shadowed:
- CP scratch registers
- CP read pointer

v2:
- Combine wb patches for r6xx-evergreen and r1xx-r5xx
- Writeback is disabled on AGP boards since it tends to be
unreliable on AGP using the gart.
- Check radeon_wb_init return values properly.

1df6a2ebd7 drm/ttm: Fix two race conditions + fix busy codepaths
This fixes a race pointed out by Dave Airlie where we don't take a buffer
object about to be destroyed off the LRU lists properly. It also fixes a rare
case where a buffer object could be destroyed in the middle of an
accelerated eviction.

The patch also adds a utility function that can be used to prematurely
release GPU memory space usage of an object waiting to be destroyed.
For example during eviction or swapout.

The above mentioned commit didn't queue the buffer on the delayed destroy
list under some rare circumstances. It also didn't completely honor the
remove_all parameter.

to avoid acquiring the work proc mutex with the struct mutex
held. This avoids inverting the lock order seen when the work proc
runs.

ab7ad7f645 drm/i915: Use pipe state to tell when pipe is off
Instead of waiting for the display line value to settle, we can simply
wait for the pipe configuration register 'state' bit to turn off.

Contrarywise, disabling the plane will not cause the display line
value to stop changing, so instead we wait for the vblank interrupt
bit to get set. And, we only do this when we're not about to wait for
the pipe to turn off.

29d08b3efd drm/gem: handlecount isn't really a kref so don't make it one.
There were lots of places being inconsistent since handle count
looked like a kref but it really wasn't.

Fix this my just making handle count an atomic on the object,
and have it increase the normal object kref.

Now i915/radeon/nouveau drivers can drop the normal reference on
userspace object creation, and have the handle hold it.

This patch fixes a memory leak or corruption on unload, because
the driver had no way of knowing if a handle had been actually
added for this object, and the fbcon object needed to know this
to clean itself up properly.

Added a function that sets the LVDS values to default settings.  This

The default settings in each parse function have been moved to the new
function. This consolidates all the default settings into one place.

The default dither bit value has been changed from 0 to 1.  We can

Also switch the remaining users of *_ACTHD to the ring-base one.
Kill the other ring-specific macros because they're now unused.

30dbf0c07f drm/i915: Adjust hangcheck EIO semantics
Owain Ainsworth reported an issue between the interaction of the
hangcheck and userspace immediately (and permanently) falling back to
s/w rasterisation. In order to break the mutex and begin resetting the
GPU, we must abort the current operation (usually within the wait) and
climb sufficiently far back up the call chain to drop the mutex. In his
implementation, Owain has a loop within the ioctl handler to detect the
hang and then sleep until the error handler has run. I've chosen to
return to userspace and report an EAGAIN which should trigger the
userspace ioctl handler to repeat the call (simply because it felt less
invasive...). Before hitting a wedged GPU, we then wait upon completion
of the error handler.

Avoid cause latencies in other clients by not taking the global struct

This patch fixes the black screen bug on Dell e6510, by
adding two delays to give the eDP panel time to turn on before we
continue with the next write.

300ms is rather arbitray and a rather long sleep, we need to find a way

    Based on a patch from Matthew Garrett.

    Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
    Acked-by: Matthew Garrett <mjg@redhat.com>

It doesn't seem to revert cleanly, but the problem lies in these
two config entries:

CONFIG_ACPI=y
CONFIG_ACPI_VIDEO=m

Adding a select for ACPI_VIDEO appears to be the best solution, and
is comparable to what is done in DRM_I915.  Builds, boots, and appears to
work correctly.

7314dec95c drm/nv17-nv4x: Fix analog load detection false positive on rare occasions.
On some boards the residual current DAC outputs can draw when they're
disconnected can be high enough to give a false load detection
positive (I've only seen it in the S-video luma output of some cards,
but just to be sure). The output line capacitance is limited and
sampling twice should fix it reliably.

4295f188e8 drm/nv20: Use the nv30 CRTC bandwidth calculation code.
nv2x CRTC FIFOs are as large as in nv3x (4kB it seems), and the FIFO
control registers have the same layout: we can make them share the
same implementation.

Previously we were using the nv1x code, but the calculated FIFO
watermarks are usually too low for nv2x and they cause horrible
scanout artifacts. They've gone unnoticed until now because we've been
leaving one of the bandwidth regs uninitialized (CRE 47, which
contains the most significant bits of FFLWM), so everything seemed to
work fine except in some cases after a cold boot, depending on the
memory bandwidth and pixel clocks used.

316f60a120 drm/nouveau: Fix suspend on some nv4x AGP cards.
On some nv4x cards (specifically, the ones that use an internal
PCIE->AGP bridge) the AGP controller state isn't preserved after a
suspend/resume cycle, and the AGP control registers have moved from
0x18xx to 0x100xx, so the FW check in nouveau_mem_reset_agp() doesn't
quite work. Check "dev->agp->mode" instead.
