If the CRTC is going from enabled to disabled and it is a port sync
slave, it needs to check to the old state to be disabled before the
port sync master.

Let's move handling and reset for gen11 display IRQs to their own
functions, similar to how we deal with GT interrupts. This will make
the top-level functions a bit easier to read and potentially make things
easier to deal with in the future if new platforms wind up needing
different display handling logic.

issue:
kernel would report a warning from a double unpin
during the driver unloading on the CSB bo
why:
we unpin it during hw_fini, and there will be another
unpin in sw_fini on CSB bo.
fix:
actually we don't need to pin/unpin it during
hw_init/fini since it is created with kernel pinned,
we only need to fullfill the CSB again during hw_init
to prevent CSB/VRAM lost after S3
v2:
get_csb in init_rlc so hw_init() will make CSIB content
back even after reset or s3
v3:
use bo_create_kernel instead of bo_create_reserved for CSB
otherwise the bo_free_kernel() on CSB is not aligned and
would lead to its internal reserve pending there forever
take care of gfx7/8 as well

Rather than assume if and only if the engine->default_state is not set
that the context is invalid, instead track when we know the context has
valid state -- either because we have copied the default_state or we
have completed a context switch to save the HW state.

swSMU is not supported because smu ip block is commented at

Generally for sriov, initialization of smu is moved to host driver.
Thus, smu sw_init and hw_init will not be executed at guest driver.
Without sw structure being initialized in guest driver, swSMU cannot

Only along the submission path can we guarantee that the locked request
is indeed from a foreign engine, and so the nesting of engine/rq is
permissible. On the submission tasklet (process_csb()), we may find
ourselves competing with the normal nesting of rq/engine, invalidating
our nesting. As we only use the spinlock for debug purposes, skip the
debug if we cannot acquire the spinlock for safe validation - catching
99% of the bugs is better than causing a hard lockup.

Some machines require ACPI for runtime resume, and ACPI is quite kmalloc
happy. We cannot handle kmalloc from inside the vm->mutex, as they are
used by the shrinker, and so we must ensure the global runtime-pm is
awake prior to unbinding to avoid the potential inversion.

When looking at SDEISR to determine the connection status of combo
outputs, we should use the phy index rather than the port index.
Although they're usually the same thing, EHL's DDI-D (port D) is
attached to PHY-A and SDEISR doesn't even have bits for a "D" output.
It's also possible that future platforms may map DDIs (the internal
display engine programming units) to PHYs (the output handling on the IO
side) in ways where port!=phy, so let's look at the PHY index by
default.
v2: Rename to intel_combo_phy_connected. (Lucas)

The variable v_total is being initialized with a value that is never
read and it is being updated later with a new value. The initialization
is redundant and can be removed.
