Let's disable all scaling that requires horizontal decimation with
higher factor than 4, until we have better estimates of what we can
and can not do. However, NV12 color format appears to work Ok with
all decimation factors.
When decimating horizontally by more that 4 the dss is not able to
fetch the data in burst mode. When this happens it is hard to tell if
there enough bandwidth. Despite what theory says this appears to be
true also for 16-bit color formats.

Move drm_atomic_helper_commit_modeset_enables() call to before
drm_atomic_helper_commit_planes() call and have a
omap_atomic_wait_for_completion() call after both.
With the current dss dispc implementation we have to enable the new
modeset before we can commit planes. The dispc ovl configuration
relies on the video mode configuration been written into the HW when
the ovl configuration is calculated.
This approach is not ideal because after a mode change the plane
update is executed only after the first vblank interrupt. The dispc
implementation should be fixed so that it is able use uncommitted drm

Until recently vlv_steal_power_sequencer() wasn't being called for
normal DP ports, and hence it could assert that it should only be
called for pipe A and B (since pipe C doesn't support eDP). However
that changed when we started to consider normal DP ports as well when
choosing a PPS. So we will now get spurious warnings when
vlv_steal_power_sequencer() does get called for pipe C. Avoid this by
moving the WARN down into vlv_detach_power_sequencer() where this
assertion should still hold.

Following a reset, the context and page directory registers are lost.
However, the queue of requests that we resubmit after the reset may
depend upon them - the registers are restored from a context image, but
that restore may be inhibited and may simply be absent from the request

prime the CCID/PD registers with the first request in the queue (even
for the hung request), we prevent invalid memory access for the

Date: Wed May 4 14:38:26 2016 +0200
drm/core: Do not preserve framebuffer on rmfb, v4.
This introduces a slight behavioral change to rmfb. Instead of
disabling a crtc when the primary plane is disabled, we try to
preserve it.
Apart from old versions of the vmwgfx xorg driver, there is
nothing depending on rmfb disabling a crtc. Since vmwgfx is
a legacy driver we can safely only disable the plane with atomic.
If this commit is rejected by the driver then we will still fall
back to the old behavior and turn off the crtc.
v2:
- Remove plane->fb assignment, done by drm_atomic_clean_old_fb.
- Add WARN_ON when atomic_remove_fb fails.
- Always call drm_atomic_state_put.
v3:
- Use drm_drv_uses_atomic_modeset
- Handle the case where the first plane-disable-only commit fails
with -EINVAL. Some drivers do not support this, fall back to
disabling all crtc's in this case.

The API is not suitable for subsystems consisting of multiple devices
and requires severe hacks to use it. To mitigate this, this patch
implements allocation and address space management locally by using
helpers provided by DRM framework, like other DRM drivers do, e.g.
Tegra.
This patch should not introduce any functional changes until the driver
is made to attach subdevices into an IOMMU domain with the generic IOMMU
API, which will happen in following patch. Based heavily on GEM

Most DRM messages include three pieces of information: the type of the
component (CRTC, ENCODER, CONNECTOR etc), the DRM object ID of the
component, and the component name. However, there are some messages
which omit the last piece of identifying information. This makes it
harder to debug failures when these messages are printed, because the
DRM object ID doesn't supply enough information to know which piece of
hardware had a problem.
Update the atomic modeset code to always print the component name along
with the type and DRM object ID.

For the inhibit ctx, load all mmio in render mmio list
into HW by MMIO write for ctx initialization.
For the none-inhibit ctx, only load the render mmio which
is not in_context into HW by MMIO write. Skip the MMIO write
for in_context mmio as context image will load it.

been cleared, we need reset display related vreg to reflect our display
setting.

descriptor but keep other valid config. This fixes GPU hang caused by
invalid descriptor submitted for gvt workload.

Add a bit needed during initialization into the driver, where it is supposed
to be. Currently, this is happening in the VCE firmware, and although
functional, this is the correct place to perform this initialization.
