dGFX has local memory so it does not have aperture or support
CPU fences but even for iGFX it have a small number of fences.
As replacement for fences to track frontbuffer modifications by CPU
we have a software tracking that is already in used by FBC and PSR.
PSR don't support fences so it shows that this tracking is reliable.
So lets make fences a nice-to-have to activate FBC for GEN9+, this
will allow us to enable FBC for dGFXs and iGFXs even when there is no
available fence.
We do not set fences to rotated planes but FBC only have restrictions
against 16bpp, so adding it here.
Also adding a new check for the tiling format, fences are only set
to X and Y tiled planes but again FBC don't have any restrictions
against tiling so adding linear as supported as well, other formats
should be added after tested but IGT only supports drawing in thse
3 formats.
intel_fbc_hw_tracking_covers_screen() maybe can also have the same
treatment as fences but BSpec is not clear if the size limitation is
for hardware tracking or general use of FBC and I don't have a 5K
display to test it, so keeping as is for safety.
v2:
- Added tiling and pixel format rotation checks
- Changed the GEN version not requiring fences to 11 from 9, DDX
needs some changes but it don't have support for GEN11+
v3:
- Changed back to GEN9+
- Moved GEN test to inside of tiling_is_valid()
v4:
- moved rotation check to its own functions
v5:
- renamed rotations_is_valid to rotation_is_valid
- moved pre-g4x rotation check to rotation_is_valid()

is_color_space_conversion() is a misnomer. It checks not only if color
space conversion is needed, but also if format conversion is needed.
This is actually desired behaviour because result of this function
determines if CSC block should be enabled or not (CSC block can also do
format conversion).
In order to clear misunderstandings, let's rework
is_color_space_conversion() to do exactly what is supposed to do and add
another function which will determine if CSC block must be enabled or
not.

Using huge page-table entries requires that the physical address of the
start of a buffer object is huge page size aligned.
Make a special version of the TTM range manager that accomplishes this,
but falls back to a smaller page size alignment (PUD->PMD, PMD->NORMAL)
to avoid eviction.
If other drivers want to use it in the future, it can be made a
TTM generic helper. Note that drivers can force eviction for a certain
alignment by assigning the TTM GPU alignment correspondingly.

Support huge (PMD-size and PUD-size) page-table entries by providing a
huge_fault() callback.
We still support private mappings and write-notify by splitting the huge
page-table entries on write-access.
Note that for huge page-faults to occur, either the kernel needs to be
compiled with trans-huge-pages always enabled, or the kernel needs to be
compiled with trans-huge-pages enabled using madvise, and the user-space
app needs to call madvise() to enable trans-huge pages on a per-mapping
basis.
Furthermore huge page-faults will not succeed unless buffer objects and
user-space addresses are aligned on huge page size boundaries.

It looks like some callers expect a non-volatile object, that they do not
want the contents of the pages lost if they happen to not be looking at it.
The shrinker however sees that we mark the pages as DONTNEED and
believes that it can freely reap them. However, since the huge object
use plain pages, they cannot be swapped out as they have no backing
storge, and the only way we can shrink them is by discarding the
contents. In light of the callers wanting to keep the contents around,
both IS_SHRINKABLE and marking the pages as volatile are incorrect.
If we drop the IS_SHRINKABLE flag we avoid the immediate issue of the
shrinker accidentally removing valuable content. We will have to
remember that a huge object is not suitable for exercising the shrinker
interaction -- although we can introduce a shrinkable one if we require.

Few edp panels like Sharp is triggering short and long
hpd pulse after panel is getting powered off.
Currently driver is already ignoring long pulse for eDP
panel but in order to process the short pulse, it turns on
the VDD which requires panel power_cycle_delay + panel_power_on_delay
these delay on Sharp panel introduced the responsiveness overhead
of 800ms in the modeset sequence and as well is in suspend
sequence.
Ignoring any short pulse if panel is powered off.
FIXME: It requires to wait for panel_power_off delay in order
to check the panel power status due to pps_lock because panel triggers
short pulse immediately after writing PP_OFF to PP_CTRL register and
wait_panel_off waits for panel_power_off delay with pps_lock held.
This still creates responsiveness overhead of panel_power_off delay.
v2:
- checking vdd along with panel power to ignore the hpd. [Jani,Ville]
v3:
- safer side check to ignore the long hpd when eDP have power,
adding type of hpd to debug log. [Jani]
