The first pass implementation of execlists required a backpointer to the context to be held

The previous patch changed the config field in intel_crtc to a pointer,
but to keep the mechanical changes (done with spatch) separate from the
new code, the pointer was made to point to a new _config field with type
struct intel_crtc_state added to that struct. This patch improves that
code by getting rid of that field, allocating a state struct in
intel_crtc_init() a keeping it properly updated when a mode set
happens.

Earlier, DRRS structures were specific to eDP (used only in intel_dp).
Since DRRS can be extended to other internal display types
(if the panel supports multiple RR), modifying structures
to be part of drm_i915_private and have a provision to add display related
structs like intel_dp.
Also, aligning with frontbuffer tracking mechanism, the new structure
contains data for busy frontbuffer bits.

On VLV/CHV the rc6 residency calculations read a second register to
determine the actual units used for the residency value. The variable
name 'reg' where that register value is stored shadows the function
argument 'reg'. That can easily leave the reader utterly confused, so
rename the internal variable to 'clk_reg'.

CherryViewA0_iGfx_BIOS_DRIVER_PUNIT_spec_y14w28d5 tells us not to enable
the RP down timeout interrupt, and says that the timeout value is hence
not used. We do enable that interrupt currently though, so leaving the
timeout as 0 results in very poor performance as the GPU frequency keeps
dropping constantly. So just program the register with the recommended
value.
Leaving the interrupt enabled doesn't seem to do any harm so far. So
I've decided to leave it on for now, just to avoid making CHV a
special case.
This fixes the performance regression from:

When we transitioned to the atomic plane helpers in commit:

drm/i915: Move to atomic plane helpers (v9)
one of the changes was to call intel_plane_destroy_state() while tearing
down a plane to prevent leaks when unloading the driver. That made
sense when the patches were first written, but before they were merged,
commit 3009c0377f25c29852b218a6933a969d02cbdc5d

drm: Free atomic state during cleanup
had already landed, which made this the responsibility of the DRM core.
The result was that we were kfree()'ing the state twice, and also
possibly double-unref'ing a framebuffer, leading to memory corruption
when the driver was unloaded.
The fix is to simply not try to cleanup the state in the i915 teardown
code now that the core handles this for us.

When creating a fence for a tiled object, only fence the area that
makes up the actual tiles. The object may be larger than the tiled
area and if we allow those extra addresses to be fenced, they'll
get converted to addresses beyond where the object is mapped. This
opens up the possiblity of writes beyond the end of object.
To prevent this, we adjust the size of the fence to only encompass
the area that makes up the actual tiles. The extra space is considered
un-tiled and now behaves as if it was a linear object.

commit 6dda730e55f412a6dfb181cae6784822ba463847
Author: Jani Nikula <jani.nikula@intel.com>

drm/i915: respect the VBT minimum backlight brightness
introduced a bug which resulted in inconsistent brightness levels on
different machines. If a suspended was entered with the screen off some
machines would resume with the screen at minimum brightness and others
at maximum brightness.
The following commands can be used to produce this behavior.
xset dpms force off
sleep 1
sudo systemctl suspend
(resume ...)
The root cause of this problem is a comparison which checks to see if
the backlight level is zero when the panel is enabled. If it is zero,
it is set to the maximum level. Unfortunately, not all machines have a
minimum level of zero. On those machines the level is left at the
minimum instead of begin set to the maximum.
Fix the bug by updating the comparison to check for the minimum
backlight level instead of zero. Also, expand the comparison for
the possible case when the level is less than the minimum.

Commit 82460d972 ("drm/i915: Rework ppgtt init to no require an aliasing

DMAR:[fault reason 23] Unknown

Further commentary from Daniel:
I sugggested this change to David after staring at the offending patch
for a while. I have no idea and theory whatsoever why this would upset
the gpu less than the other way round. But it seems to work. David
promised to chase hw people a bit more to get a more meaningful answer.
Wrt the comment that this deletes: I've done some digging and afaict
loading context before ppgtt enable was once required before our recent
restructuring of the context/ppgtt init code: Before that context sw
setup (i.e. allocating the default context) and hw setup was smashed
together. Also the setup of the default context was the bit that
actually allocated the aliasing ppgtt structures. Which is the reason
for the context before ppgtt depency.
Or was, since with all the untangling there's no no real depency any
more (functional, who knows what the hw is doing), so the comment is
just stale.

This is an important optimization for avoiding read-after-write (RAW)
stalls in the HiZ buffer. Certain workloads would run very slowly with
HiZ enabled, but run much faster with the "hiz=false" driconf option.
With this patch, they run at full speed even with HiZ.
Improves performance in OglVSInstancing by 3.2x on Broadwell GT3e
(Iris Pro 6200).
Thanks to Jesse Barnes and Ben Widawsky for their help in tracking this
down. Thanks to Chris Wilson for showing me the new workarounds system.

It is useful to know at debug time if we are keeping main link on.

No functional changes on this patch. Just grouping the link_standy decision
to avoid miss any change. Also making this info available everywhere
which will help to decide when to use vbt's tp time on following patch.

We have only two possible states with so many names and combinations that
might be confusing.
1 - Main link active / enabled / stand by / on
2 - Main link disabled / off / full off
Let's start organizing it by fixing a inverted logic when setting the sink bit.

ON these platforms we don't have hardware tracking working for any case.
So we need to fake this on software by forcing psr to exit on every
flush.
Manual tests indicated this was needed.

915 doens't support hotplug at all, so we shouldn't try to pretend
otherwise in the SDVO code.
Note: i915 does have hotplug support in hw, we simply never enabled it
in i915.ko: There's only one hpd bit for all outputs, so not worth the
bother to add this special case for this rather old platform.

If we determine that a specific port is eDP, don't register the HDMI
connector/encoder for it. The reason being that we want to disable
HPD interrupts for eDP ports when the display is off, but the presence
of the extra HDMI connector would demand the HPD interrupt to remain
enabled all the time.

The dev_priv->display.hpd_irq_setup hook is optional, so we can move the
I915_HAS_HOTPLUG() check out of i915_hpd_irq_setup() and only set up the
hook when hotplug support is present.

intel_hpd_irq_handler() walks the passed in hpd[] array assuming it
contains HPD_NUM_PINS elements. Currently that's not true as we don't
specify an explicit size for the arrays when initializing them. Avoid
the out of bounds accesses by specifying the size for the arrays.

This reverts commit 5a0afd4b78ec23f27f5d486ac3d102c2e8d66bd7.
Although timeout mode allows higher residency it impact badly on performance.
I believe while we don't have a way to balance between performance and
power savings at runtime I believe we have to revert and prioritize
performance that was impacted a lot.
