There was a integer wraparound when mode_clock became too high,
and we didn't correct for the FEC overhead factor when dividing,
with the calculations breaking at HBR3.
As a result our calculated bpp was way too high, and the link width
limitation never came into effect.
Print out the resulting bpp calcululations as a sanity check, just
in case we ever have to debug it later on again.
We also used the wrong factor for FEC. While bspec mentions 2.4%,
all the calculations use 1/0.972261, and the same ratio should be
applied to data M/N as well, so use it there when FEC is enabled.
This fixes the FIFO underrun we are seeing with FEC enabled.
Changes since v2:
- Handle fec_enable in intel_link_compute_m_n, so only data M/N is adjusted. (Ville)
- Fix initial hardware readout for FEC. (Ville)
Changes since v3:
- Remove bogus fec_to_mode_clock. (Ville)

Modern platforms allow the transcoders hdisplay/vdisplay to exceed the
planes' max resolution. This has the nasty implication that modes on the
connectors' mode list may not be usable when the user asks for a
fullscreen plane. Seeing as that is the most common use case it seems
prudent to filter out modes that don't allow for fullscreen planes to
be enabled.
Let's do that in the connetor .mode_valid() hook so that normally
such modes are kept hidden but the user is still able to forcibly
specify such a mode if they know they don't need fullscreen planes.
This is in line with ealier policies regarding certain clock limits.
The idea is to prevent the casual user from encountering a mode that
would fail under typical conditions, but allow the expert user to
force things if they so wish.
Maybe in the future we should consider automagically using two
planes when one can't cover the entire screen? Wouldn't be a
great match for the current uapi with explicit planes though,
but I guess no worse than using two pipes (which we apparently
have to in the future anyway). Either that or we'd have to
teach userspace to do it for us.

The officially validated plane width limit is 4k on skl+, however
we already had people using 5k displays before we started to enforce
the limit. Also it seems Windows allows 5k resolutions as well
(though not sure if they do it with one plane or two).
According to hw folks 5k should work with the possible
exception of the following features:
- Ytile (already limited to 4k)
- FP16 (already limited to 4k)
- render compression (already limited to 4k)
- KVMR sprite and cursor (don't care)
- horizontal panning (need to verify this)
- pipe and plane scaling (need to verify this)
So apart from last two items on that list we are already
fine. We should really verify what happens with those last
two items but I don't have a 5k display on hand atm so it'll
have to wait.
In the meantime let's just bump the limit back up to 5k since
several users have already been using it without apparent issues.
At least we'll be no worse off than we were prior to lowering
the limits.

Stop setting ->pipe_mask to zero when display is disabled, allowing us
to have different code paths for not actually having display hardware,
and having display hardware disabled. This lets us develop those two
avenues independently.
There are no functional changes for when there is no display. However,
all uses of for_each_pipe() and for_each_pipe_masked() will start
running for the disabled display case. Put one of the more significant
ones behind checks for INTEL_DISPLAY_ENABLED(), otherwise the cases
should not be hit with disabled display, or they seem benign. Fingers
crossed.
All in all, this might not be the ideal solution. In fact we may have
had something along the lines of this in the past, but we ended up
conflating the two cases. Possibly even by recommendation by yours
truly; I did not dare dig up that part of the history. But the perfect
is the enemy of the good, this is a straightforward change, and lets us
get actual work done in both fronts without interfering with each other.

Prepare for making a distinction between not having display and having
disabled display. Add INTEL_DISPLAY_ENABLED() and use it where
HAS_DISPLAY() is used after intel_device_info_runtime_init(). This is
initially duplication, as disabling display still leads to ->pipe_mask =
0 and HAS_DISPLAY() being false.
Note that ever since i915.display_disable was introduced, it has not
affected PCH detection even if it uses HAS_DISPLAY(), as display disable
happens after that.
Since INTEL_DISPLAY_ENABLED() will not make sense unless HAS_DISPLAY()
is true, include a warning for catching misuses making decisions on
INTEL_DISPLAY_ENABLED() when HAS_DISPLAY() is false.

obj->pin_global was originally used as a means to keep the shrinker off
the active scanout, but we use the vma->pin_count itself for that and
the obj->frontbuffer to delay shrinking active framebuffers. The other
role that obj->pin_global gained was for spotting display objects inside
GEM and working harder to keep those coherent; for which we can again
simply inspect obj->frontbuffer directly.
Coming up next, we will want to manipulate the pin_global counter
outside of the principle locks, so would need to make pin_global atomic.
However, since obj->frontbuffer is already managed atomically, it makes
sense to use that the primary key for display objects instead of having
pin_global.
Ville pointed out the principle difference is that obj->frontbuffer is
set for as long as an intel_framebuffer is attached to an object, but
obj->pin_global was only raised for as long as the object was active. In
practice, this means that we consider the object as being on the scanout
for longer than is strictly required, causing us to be more proactive in
flushing -- though it should be true that we would have flushed
eventually when the back became the front, except that on the flip path
that flush is async but when hit from another ioctl it will be
synchronous.

There is a difference in BSpec's and the driver's designation of DDI
ports. BSpec uses the following names:
- before GEN11:
BSpec/driver:
port A/B/C/D etc
- GEN11:
BSpec/driver:
port A-F
- GEN12:
BSpec:
port A/B/C for combo PHY ports
port TC1-6 for Type C PHY ports
driver:
port A-I.
The driver's port D name matches BSpec's TC1 port name.
So far power domains were named according to the BSpec designation, to
make it easier to match the code against the specification. That however
can be confusing when a power domain needs to be matched to a port on
GEN12+. To resolve that use the driver's port A-I designation for power
domain names too and rename the corresponding power wells so that they
reflect the mapping from the driver's to BSpec's port name.

The current SKUs added for Tiger Lake don't have DDIC hooked up, even
though it is supported by the SoC. The current state for these SKUs is
problematic since while enabling the combo phy, PORT_COMP_DW* return
0xFFFFFFFF, which is invalid per register definition.
During initialization we check what phys are not yet enabled by reading
PHY_MISC_C and try to enable it by toggling the "DE to IO Comp Pwr Down"
bit. But after that any read to the PORT_COMP_DW* returns invalid
results. This removes the following warning

We may or may not need to change the implementation to account for DDIC
being available on other SKUs. For now I think the best thing to do is
to just disable the port.

To reduce the number of explicit dev_priv->uncore calls in the display
code ahead of the introduction of dev_priv->de_uncore, this patch
introduces a wrapper for one of the main usages of it, the register
waits. When we transition to the new uncore, we can just update the
wrapper to point to the appropriate structure.
Since the vast majority of waits are on a set or clear of a bit or mask,
add set & clear flavours of the wrapper to simplify the code.

Move the active tracking for the frontbuffer operations out of the
i915_gem_object and into its own first class (refcounted) object. In the
process of detangling, we switch from low level request tracking to the
easier i915_active -- with the plan that this avoids any potential
atomic callbacks as the frontbuffer tracking wishes to sleep as it
flushes.

The fb_base is only used for communicating the GTT BAR from one piece of
the display code (kms setup) to another (fbdev). What is required in the
fbdev is just the aperture address which should be derived from the
bo we allocate for the framebuffer directly.
The same appears true for drm/; it is not used by the core or the uAPI,
it is merely for conveniently passing a device address from bit of
display management code to another.
v2: Note that since we only expose enough of a system map to cover our
single framebuffer, the screen_base/size and the smem are one and the
same.

There's still plenty to clean up, but start off with moving the file
