Ville Syrjälä 73008b989f drm/i915: Clean up VLV rps code a bit
Always print both the MHz value and raw register value for rps stuff.

Also kill a somewhat pointless local 'rpe' variable and just use
dev_priv->rps.rpe_delay.

While at it clean up the caps in "GPU" and "Punit" debug messages.

Chris Wilson a35cdaa0e1 drm/i915: Detect invalid scanout pitches
Report back the user error of attempting to setup a CRTC with an invalid
framebuffer pitch. This is trickier than it should be as on gen4, there
is a restriction that tiled surfaces must have a stride less than 16k -
which is less than the largest supported CRTC size.

v2: Fix the limits for gen3
v3: Move check into intel_framebuffer_init() and fix VLV limits. (vsyrjala)
v4: Use idiomatic '>=' for generation checks

There are legit cases, e.g. when userspace asks for something

Konrad Rzeszutek Wilk 1625e7e549 drm/i915: make compact dma scatter lists creation work with SWIOTLB backend.
Git commit 90797e6d1e
("drm/i915: create compact dma scatter lists for gem objects") makes
certain assumptions about the under laying DMA API that are not always
correct.

On a ThinkPad X230 with an Intel HD 4000 with Xen during the bootup
I see:

[drm:intel_pipe_set_base] *ERROR* pin & fence failed
[drm:intel_crtc_set_config] *ERROR* failed to set mode on [CRTC:3], err = -28

Bit of debugging traced it down to dma_map_sg failing (in
i915_gem_gtt_prepare_object) as some of the SG entries were huge (3MB).

That unfortunately are sizes that the SWIOTLB is incapable of handling -
the maximum it can handle is a an entry of 512KB of virtual contiguous
memory for its bounce buffer. (See IO_TLB_SEGSIZE).

Previous to the above mention git commit the SG entries were of 4KB, and
the code introduced by above git commit squashed the CPU contiguous PFNs
in one big virtual address provided to DMA API.

This patch is a simple semi-revert - were we emulate the old behavior
if we detect that SWIOTLB is online. If it is not online then we continue
on with the new compact scatter gather mechanism.

An alternative solution would be for the the '.get_pages' and the
i915_gem_gtt_prepare_object to retry with smaller max gap of the
amount of PFNs that can be combined together - but with this issue
discovered during rc7 that might be too risky.

Paulo Zanoni 15b1d171d8 drm/i915: fix the "ghost eDP" encoder unwind path
Because calling intel_dp_encoder_destroy inside
intel_edp_init_connector is just wrong. This is the initialization
path, so we should properly unwind all the initialization through the
whole caller stack.

On the intel_dp_encoder_destroy function we do the following:
1 - Call i2c_del_adapter
2 - Call drm_encoder_cleanup
3 - If edp:
3.1 - Cancel panel_vdd_work
3.2 - Call ironlake_panel_vdd_of_sync
4 - Free the encoder

And here is how we unwind each specific step:
1 - We have intel_dp_init_connector -> intel_dp_i2c_init ->
    i2c_dp_aux_add_bus -> i2c_add_adapter, so we call
    i2c_del_dapter at intel_dp_init_connector
2 - Call it in the same function that called drm_encoder_init
3 - Call it in the same function that called INIT_DELAYED_WORK
4 - Free it in the same function that allocated it

Paulo Zanoni 16c255335b drm/i915: propagate errors from intel_dp_init_connector
In case we detect a "ghost eDP", intel_edp_init_connector frees both
the connector and encoder and then returns. On Haswell, intel_ddi_init
then tries to use the freed encoder on the HDMI initialization path
since the following commit:

    drm/i915: don't setup hdmi for port D edp in ddi_init

So now on intel_ddi_init we check for the "ghost eDP" case and return
without trying to initialize HDMI. This way we won't try to read the
freed "intel_encoder" struct in the next "if" statement.

Paulo Zanoni acd8db100e drm/i915: don't check encoder at DP connector destroy()
By the time we call intel_dp_destroy (which destroys the connector)
the encoder may have been destroyed already, so if we use it we may be
reading some free memory. That happens in drm_mode_config_cleanup()
and also inside intel_dp_init_connector() when we detect a ghost eDP.

I also hope this may solve some random memory bugs.

Dave Airlie d482e5fa29 Revert "drm: kms_helper: don't lose hotplug event"
This reverts commit 160954b7bc.

This was rearming the workqueue with a 0 timeout, causing
a WARN_ON, and possible loop.

Daniel writes:
"I've looked a bit into this and I think we need to have a separate
work struct for recovering these lost hotplug events since the
continuous self-rearming case is a real risk (e.g. if a connector
flip-flops all the time). At least I don't see a sane way to block out
re-arming with the current code in a simple way. So reverting the
offender seems like the right thing and I'll go back to the drawing
board for 3.12."
