Ville Syrjälä 40b2be419f drm/i915: Dump 'output_types' in crtc state dump
To make it easier to debug things let's dump the output types bitmask in
the crtc state dump. And to make life that much better, let's pretty
print it as a a human reaadable string as well.

v2: Have the caller pass in the buffer (Chris)
    #undef OUTPUT_TYPE (Jani)

Ville Syrjälä de33081567 drm/i915: Reuse normal state readout for LVDS/DVO fixed mode
Reuse the normal state readout code to get the fixed mode for LVDS/DVO
encoders. This removes some partially duplicated state readout code
from LVDS/DVO encoders. The duplicated code wasn't actually even
populating the negative h/vsync flags, leading to possible state checker
complaints. The normal readout code populates that stuff fully.

Chris Wilson 3bd4073524 drm/i915: Consolidate get_fence with pin_fence
Following the pattern now used for obj->mm.pages, use just pin_fence and
unpin_fence to control access to the fence registers. I.e. instead of
calling get_fence(); pin_fence(), we now just need to call pin_fence().
This will make it easier to reduce the locking requirements around
fence registers.

Ville Syrjälä e30a154b52 drm/i915: Read timings from the correct transcoder in intel_crtc_mode_get()
intel_crtc->config->cpu_transcoder isn't yet filled out when
intel_crtc_mode_get() gets called during output probing, so we should
not use it there. Instead intel_crtc_mode_get() figures out the correct
transcoder on its own, and that's what we should use.

If the BIOS boots LVDS on pipe B, intel_crtc_mode_get() would actually
end up reading the timings from pipe A instead (since PIPE_A==0),
which clearly isn't what we want.

It looks to me like this may have been broken by
commit eccb140bca ("drm/i915: hw state readout&check support for cpu_transcoder")
as that one removed the early initialization of cpu_transcoder from
intel_crtc_init().

In legacy cursor updates we need the extra vblank waits if we update

This is why for < gen9 we disabled the cursor fastpath, but we can skip

Maarten Lankhorst 3cf50c63a7 drm/i915: Unset legacy_cursor_update early in intel_atomic_commit, v3.
Commit b44d5c0c10 ("drm/i915: Always wait for flip_done, v2.") removed
the call to wait_for_vblanks and replaced it with flip_done.

Unfortunately legacy_cursor_update was unset too late, and the
replacement call drm_atomic_helper_wait_for_flip_done() was
a noop. Make sure that its unset before setup_commit() is
called to fix this issue.

Changes since v1:
- Force vblank wait for watermarks not yet converted to atomic too. (Ville)
- Use for_each_new_intel_crtc_in_state. (Ville)
Changes since v2:
- Move the optimization to a separate commit. (Ville)

Imre Deak ed69cd4068 drm/i915/glk, cnl: Implement WaDisableScalarClockGating
On GLK and CNL enabling a pipe with its pipe scaler enabled will result
in a FIFO underrun. This happens only once after driver loading or
system/runtime resume, more specifically after power well 1 gets
enabled; subsequent modesets seem to be free of underruns. The BSpec
workaround for this is to disable the pipe scaler clock gating for the
duration of modeset. Based on my tests disabling clock gating must be
done before enabling pipe scaling and we can re-enable it after the pipe
is enabled and one vblank has passed.

For consistency I also checked if plane scaling would cause the same
problem, but that doesn't seem to trigger this problem.

The patch is based on an earlier version from Ander.

v2 (Rodrigo):
- Set also CLKGATE_DIS_PSL bits 8 and 9.
- Add also the BSpec workaround ID.

As realised by commit 9e3d6223d2 ("math64, timers: Fix 32bit

for performing a 32b x 32b multiply returning a 64b result (i.e. where
we idiomatically use u64 result = (u64)x * (u32)x). This catches a
couple of instances in the display code using (u64)x * (u32)y.

Maarten Lankhorst 669c9215af drm/atomic: Make async plane update checks work as intended, v2.
By always keeping track of the last commit in plane_state, we know
whether there is an active update on the plane or not. With that
information we can reject the fast update, and force the slowpath
to be used as was originally intended.

We cannot use plane_state->crtc->state here, because this only mentions
the most recent commit for the crtc, but not the planes that were part
of it. We specifically care about what the last commit involving this
plane is, which can only be tracked with a pointer in the plane state.

Changes since v1:
- Clean up the whole function here, instead of partially earlier.
- Add mention in the commit message why we need commit in plane_state.
- Swap plane->state in intel_legacy_cursor_update, instead of
  reassigning all variables. With this commit We know that the cursor
  is not part of any active commits so this hack can be removed.

Maarten Lankhorst 21a01abbe3 drm/atomic: Fix freeing connector/plane state too early by tracking commits, v3.
Currently we neatly track the crtc state, but forget to look at
plane/connector state.

When doing a nonblocking modeset, immediately followed by a setprop
before the modeset completes, the setprop will see the modesets new
state as the old state and free it.

This has to be solved by waiting for hw_done on the connector, even
if it's not assigned to a crtc. When a connector is unbound we take
the last crtc commit, and when it stays unbound we create a new
fake crtc commit for that gets signaled on hw_done for all the
planes/connectors.

We wait for it the same way as we do for crtc's, which will make
sure we never run into a use-after-free situation.

Changes since v1:
- Only create a single disable commit. (danvet)
- Fix leak in intel_legacy_cursor_update.
Changes since v2:
- Make reference counting in drm_atomic_helper_setup_commit

Kumar, Mahesh 2503a0fef2 drm/i915/bxt+: Enable IPC support
This patch adds IPC support. This patch also enables IPC in all supported
platforms based on has_ipc flag.
IPC (Isochronous Priority Control) is the hardware feature, which
dynamically controls the memory read priority of Display.

When IPC is enabled, plane read requests are sent at high priority until
filling above the transition watermark, then the requests are sent at
lower priority until dropping below the level 0 watermark.
The lower priority requests allow other memory clients to have better
memory access. When IPC is disabled, all plane read requests are sent at
high priority.

Changes since V1:
 - Remove commandline parameter to disable ipc
 - Address Paulo's comments
Changes since V2:
 - Address review comments
 - Set ipc_enabled flag
Changes since V3:
 - move ipc_enabled flag assignment inside intel_ipc_enable function
Changes since V4:
 - Re-enable IPC after suspend/resume
Changes since V5:
 - Enable IPC for all gen >=9 except SKL
Changes since V6:
 - fix commit msg
 - after resume program IPC based on SW state.
Changes since V7:
 - Modify IPC support check based on HAS_IPC macro (suggested by Chris)

Ville Syrjälä 9c61de4c69 drm/i915: Consolidate max_cdclk_freq check in intel_crtc_compute_min_cdclk()
Currently the .modeset_calc_cdclk() hooks check the final cdclk value
against the max allowed. That's not really sufficient since the low
level calc_cdclk() functions effectively clamp the minimum required
cdclk to the max supported by the platform. Hence if the minimum
required exceeds the platforms capabilities we'd keep going anyway
using the max cdclk frequency.

To fix that let's move the check earlier into
intel_crtc_compute_min_cdclk() and we'll check the minimum required
cdclk of the pipe against the maximum supported by the platform.

that the pipes produce two pixels per clock).

Ville Syrjälä 6e64462694 drm/i915: Beef up the IPS vs. CRC workaround
Oneshot disabling of IPS when CRC capturing is started is insufficient.
IPS may get re-enabled by any plane update, and hence tests that keep
CRC capturing on across plane updates will start to see inconsistent
results as soon as IPS kicks back in. Add a new knob into the crtc state
to make sure IPS stays disabled as long as CRC capturing is enabled.

Forcing a modeset is the easiest way to handle this since that's already
how we do the panel fitter workaround. It's a little heavy handed just
for IPS, but seeing as we might already do the panel fitter workaround
I think it's better to follow that. We migth want to optimize both cases
later if someone gets too upset by the extra delay from the modeset.

v2: Check the right thing when deciding whether to force a modeset
v3: Rebase, check HAS_IPS before forcing a modeset,
    move ips_force_disable check into pipe_config_supports_ips()
