BSpec says we shouldn't enable FBC on HSW/BDW when the pipe pixel rate
exceeds 95% of the core display clock.
v2:
- HSW also needs the WA (Ville).
- Add the WA name (Ville).
- Use the current cdclk (Ville).

And also print the threshold. I was surprised to see a log message
claiming the CFB size was 32mb when there was less than 24mb available

The FBC hardware for these platforms doesn't have access to the
bios_reserved range, so it always assumes the maximum (8mb) is used.
So avoid this range while allocating.
This solves a bunch of FIFO underruns that happen if you end up
putting the CFB in that memory range. On my machine, with 32mb of
stolen, I need a 2560x1440 mode for that.

Move the sprite/cursor plane disabling to occur in intel_sanitize_crtc()
where it belongs instead of doing it in intel_modeset_readout_hw_state().
The plane disabling was first added in
4cf0ebbd4fafbdf8e6431dbb315e5511c3efdc3b drm/i915: Rework plane readout.
I got the idea from some patches from Partik and/or Maarten but those
moved also the plane state readout to intel_sanitize_crtc() which isn't
quite right in my opinion.

The Bspec is very clear that Live status must be checked about before
trying to read EDID over DDC channel. This patch makes sure that HDMI
EDID is read only when live status is up.
The live status doesn't seem to perform very consistent across various
platforms when tested with different monitors. The reason behind that is
some monitors are late to provide right voltage to set live_status up.
So, after getting the interrupt, for a small duration, live status reg
fluctuates, and then settles down showing the correct staus.
This is explained here in, in a rough way:
HPD line ________________
|\ T1 = Monitor Hotplug causing IRQ
| \______________________________________
| |
| |
| | T2 = Live status is stable
| | _____________________________________
| | /|
Live status _____________|_|/ |
| | |
| | |
| | |
T0 T1 T2
(Between T1 and T2 Live status fluctuates or can be even low, depending on
the monitor)
After several experiments, we have concluded that a max delay
of 30ms is enough to allow the live status to settle down with
most of the monitors. This total delay of 30ms has been split into
a resolution of 3 retries of 10ms each, for the better cases.
This delay is kept at 30ms, keeping in consideration that, HDCP compliance
expect the HPD handler to respond a plug out in 100ms, by disabling port.
v2: Adding checks for VLV/CHV as well. Reusing old ibx and g4x functions
to check digital port status. Adding a separate function to get bxt live
status (Daniel)
v3: Using intel_encoder->hpd_pin to check the live status (Siva)
Moving the live status read to intel_hdmi_probe and passing parameter
to read/not to read the edid. (me)
v4:
* Added live status check for all platforms using
intel_digital_port_connected.
* Rebased on top of Jani's DP cleanup series
* Some monitors take time in setting the live status. So retry for few
times if this is a connect HPD
v5: Removed extra "drm/i915" from commit message. Adding Shashank's sob
which was missed.
v6: Drop the (!detect_edid && !live_status check) check because for DDI
ports which are enumerated as hdmi as well as DP, we don't have a
mechanism to differentiate between DP and hdmi inside the encoder's
hot_plug. This leads to call to the hdmi's hot_plug hook for DP as well
as hdmi which leads to issues during unplug because of the above check.
v7: Make intel_digital_port_connected global in this patch, some
reformatting of while loop, adding a print when live status is not
up. (Rodrigo)
v8: Rebase it on nightly which involved skipping the hot_plug hook for now
and letting the live_status check happen in detect until the hpd handling
part is finalized (Daniel)

This patch modifies dsi_prepare() function to support the same

1. BXT port control register is different than VLV.
2. BXT modeset sequence needs vdisplay and hdisplay programmed

3. BXT can select PIPE for MIPI transcoders.
4. BXT needs to program register MIPI_INIT_COUNT for both the ports,
even if only one is being used.

Clearing the watermarks for all pipes/planes when updating the
watermarks for a single CRTC change seems like the wrong thing to
do here. As is, this code will ony update any pipe/plane watermarks
that need updating and leave the remaining set to zero. Later, the
watermark checks in check_wm_state() will flag these zero'd out pipe/plane
watermarks and throw errors.
By clearing only the watermark values associated with the specific crtc
the other watermark values may remain unchanged.

This stolen reserved stuff was introduced on g4x, so no need to waste
stolen on older platforms. Unfortunately configdb is no more so I can't
look up the right way to detect this stuff. I do have one hint as to
where the register might be on ctg, but I don't have a ctg to test it,
and on the elk I have here it doesn't contain sensible looking data.
For ilk grits suggegsts it might be in the same place as on snb (the
original PCI reg, not the mirror) but I can't be entirely sure about it
The register shows a round zero on my ilk.
So when there's no really good data for any of these platforms leave the
current "assume 1MiB" approach in place.

v4: Set seqno back to ~0 - 0x1000 at start-of-day, and increment by 0x100
on reset.
This makes it obvious which bbs are which after a reset. (David Gordon
& John Harrison)
Rebase.
v5: Rebase. Fixed rebase breakage. Put context pinning in separate
function. Removed code churn. (Thomas Daniel)
v6: Cleanup up issues introduced in v2 & v5 (Thomas Daniel)

This avoids some bad register writes and generally feels more correct
than unconditionally trying to redirect interrupts and such.

When WaEnableForceRestoreInCtxtDescForVCS is required, it is only
safe to send new contexts if the last reported event is "active to
idle". Otherwise the same context can fully preempt itself because
lite-restore is disabled.

Instead of doing a hack during primary plane commit the state
is updated during atomic evasion. It handles differences in
pipe size and the panel fitter.
This is continuing on top of Daniel's work to make faster
modesets atomic, and not yet enabled by default.
