drm/i915: Distribute switch variables for initialization
Variables declared in a switch statement before any case statements
cannot be automatically initialized with compiler instrumentation (as
they are not part of any execution flow). With GCC's proposed automatic
stack variable initialization feature, this triggers a warning (and they
don't get initialized). Clang's automatic stack variable initialization
(via CONFIG_INIT_STACK_ALL=y) doesn't throw a warning, but it also
doesn't initialize such variables[1]. Note that these warnings (or silent
skipping) happen before the dead-store elimination optimization phase,
so even when the automatic initializations are later elided in favor of
direct initializations, the warnings remain.
To avoid these problems, move such variables into the "case" where
they're used or lift them up into the main function body.

Currently, the only thing that can stop us from using the

error (e.g. OOM); given that if we hit such an error we can't really
fall-back to anything, we can "officialize" the FW fetching completion
as the moment at which we're committing to using GuC.
To better differentiate this case, the uses_guc check, which indicates
that GuC is supported and was selected in modparam, is renamed to
wants_guc and a new uses_guc is introduced to represent the case were
we're committed to using the GuC. Note that uses_guc does still not imply
that the blob is actually loaded on the HW (is_running is the check for
that). Also, since we need to have attempted the fetch for the result
of uses_guc to be meaningful, we need to make sure we've moved away

drm/i915/uc: autogenerate uC checker functions
We want to map uC-level checks to GuC/HuC-level ones. The mapping from
the uC state to the GuC/HuC one follows the same pattern for all the
functions:
uc_xxx_guc() -> guc_is_yyy()
So we can easily use a macro to autogenerate the functions via macros by
passing in the 2 mapped states.

drm/i915: Force state->modeset=true when distrust_bios_wm==true
Currently when we load the driver we set distrust_bios_wm=true, which
will cause active_pipe_changes to get flagged even when we're not
toggling any pipes on/off. The reason being that we want to fully
redistribute the dbuf among the active pipes and ignore whatever
state the firmware left behind.
Unfortunately when the code flags active_pipe_changes it doesn't
set state->modeset to true, which means the hardware dbuf state
won't actually get updated. Hence the hardware and software
states go out of sync, which can result in planes trying to use a
disabled dbuf slice. Suprisingly that only seems to corrupt the
display rather than making the whole display engine keel over.
Let's fix this for now by flagging state->modeset whenever
distrust_bios_wm is set.
Eventually we'll likely want to rip out all of this mess and
introduce proper statye tracking for dbuf. But that requires
more work. Toss in a FIXME to that effect.

Currently on execlists, we use a local hwsp for the kernel_context,

However, seqno wrap requires allocating a new HWSP cacheline, and may
require pinning a new HWSP page in the GGTT. This operation requiring
pinning in the GGTT is not allowed within the kernel_context timeline,
as doing so may require re-entering the kernel_context in order to evict

However to do so we must prevent the use of semaphores reading the
kernel_context's HWSP, as the use of semaphores do not support rollover
onto the same cacheline. Fortunately, the kernel_context is mostly
isolated, so unlikely to give benefit to semaphores.
