Replace the commit output state function with a simple swap of states.
Note that we still need to reconcile the legacy state after the swap,
since there are still code that relies on those.
Also note that even though changes to the state of a crtc different than
the one passed as an argument to __intel_set_mode() will be saved, the
modeset logic still deals with only one crtc.

When a new pipe_config is calculated, the fields related to shared dplls
are reset, under the assumption that they will be recalculated as part
of the modeset, which is true with the current state of the code.
As we convert to atomic, however, it will be possible to calculate a new
pipe_config and skip the modeset. In that case, after the state swap we
still want the shared dplls to be preserved.

Replace the drivers own logic for computing mode_changed, active_changed
and planes_changed flags with the check_modeset() atomic helper. Since
that function needs to compare the crtc's new mode with the current,
this patch also moves the set up of crtc_state->mode earlier in the call
chain.
Note that for the call to check_plane() to work properly, we need to
check new plane state against new crtc state. But since we still use the
plane update helper, which doesn't have a full atomic state, we need to
hack around that in intel_plane_atomic_check().

In a follow up patch the function that computes mode changes will be
replaced with the one from the atomic helpers. To preserve the behavior
of legacy modeset forcing DPMS on, that function will need to detect a
change in the active state of the crtc, so that has to be kept up to
date.

first the old staged config and then populating the atomic state based
on that. Change this to use only the atomic state.
Note that now the staged config is updated in the function
intel_modeset_commit_output_state(). This is done so that the modeset
check and the force restore path in the hw state read out code continue

The remaining parts of the failure path could only be reached if the
allocation of crtc_state_copy would fail. In that case, there is nothing
to undo, so just get rid of the label for error handling and return an
error code immediately.
We also always allocate a pipe_config, even if the pipe is being
disabled, so the remaining part of what was the error/done case can be
simplified a little too.

The first function calls done in that function can still cause changes

Set the mode_changed field on the crtc_states and use that instead.
Note that even though this patch doesn't completely replace the logic in
intel_modeset_affected_pipes(), that logic was never fully used to its
full extent. Since the commit mentioned below, modeset_pipes and
prepare_pipes would only contain at most the pipe for which the set_crtc
ioctl was called. We can grow back that logic when the time comes.

support to be able to disable the primary plane. But with primary

atomic conversion.

This patch adds 3 debugfs files for handling Displayport compliance testing
and supercedes the previous patches that implemented debugfs support for
compliance testing. Those patches were:
- [PATCH 04/17] drm/i915: Add debugfs functions for Displayport
compliance testing
- [PATCH 08/17] drm/i915: Add new debugfs file for Displayport
compliance test control
- [PATCH 09/17] drm/i915: Add debugfs write and test param parsing
functions for DP test control
This new patch simplifies the debugfs implementation by places a single
test control value into an individual file. Each file is readable by
the usersapce application and the test_active file is writable to
indicate to the kernel when userspace has completed its portion of the
test sequence.
Replacing the previous files simplifies operation and speeds response
time for the user app, as it is required to poll on the test_active file
in order to determine when it needs to begin its operations.
V2:
- Updated the test active variable name to match the change in
the initial patch of the series
V3:
- Added a fix in the test_active_write function to prevent a NULL pointer
dereference if the encoder on the connector is invalid

complaince tests
Updates the EDID compliance test function to perform the analyze and react to
the EDID data read as a result of a hot plug event. The results of this
analysis are handed off to userspace so that the userspace app can set the
display mode appropriately for the test result/response.
The compliance_test_active flag now appears at the end of the individual
test handling functions. This is so that the kernel-side operations can
be completed without the risk of interruption from the userspace app
that is polling on that flag.
V2:
- Addressed mailing list feedback
- Removed excess debug messages
- Removed extraneous comments
- Fixed formatting issues (line length > 80)
- Updated the debug message in compute_edid_checksum to output hex values
instead of decimal
V3:
- Addressed more list feedback
- Added the test_active flag to the autotest function
- Removed test_active flag from handler
- Added failsafe check on the compliance test active flag
at the end of the test handler
- Fixed checkpatch.pl issues
V4:
- Removed the checksum computation function and its use as it has been
rendered superfluous by changes to the core DRM EDID functions
- Updated to use the raw header corruption detection mechanism
- Moved the declaration of the test_data variable here
V5:
- Update test active flag variable name to match the change in the
first patch of the series.
- Relocated the test active flag declaration and initialization
to this patch
V6:
- Updated to use the new flag for raw EDID header corruption
- Removed the extra EDID read from the autotest function
- Added the edid_checksum variable to struct intel_dp so that the
autotest function can write it to the sink device
- Moved the update to the hpd_pulse function to another patch
- Removed extraneous constants
V7:
- Fixed erroneous placement of the checksum assignment. In some cases
such as when the EDID read fails and is NULL, this causes a NULL ptr
dereference in the kernel. Bad news. Fixed now.
V8:
- Updated to support the kfree() on the EDID data added previously
V9:
- Updated for the long_hpd flag propagation
V10:
- Updated to use actual checksum from the EDID read that occurs during
normal hot plug path execution
- Removed variables from intel_dp struct that are no longer needed
- Updated the patch subject to more closely match the nature and contents
of the patch
- Fixed formatting problem (long line)
V11:
- Removed extra debug messages
- Updated comments to be more informative
- Removed extra variable
V12:
- Removed the 4 bit offset of the resolution setting in compliance data
- Changed to DRM_DEBUG_KMS instead of DRM_DEBUG_DRIVER
