A GuC context and a HW context are in no way related, so the name "GuC context descriptor"
is very unfortunate, because a new reader of the code gets overwhelmed very quickly with
a lot of things called "context" that refer to different things. We can improve legibility
a lot by simply renaming a few objects in the GuC code.
v2:
- Rebased
- s/ctx_desc_pool/stage_desc_pool
- Move some explanations to the definition of the guc_stage_desc struct (Chris)
v3:
- Calculate gemsize with less intermediate steps (Joonas)
- Use BIT() macro (Joonas)

It's mandatory and it gets created if and only if GuC submission is enabled, so that should be
the condition for informing the GuC about it.
Also s/guc_addon_create/guc_ads_create and s/guc_addon_destroy/guc_ads_destroy and, while
at it, add an explanation of what things go inside the ADS object.

The GuC descriptor is big in size. If we use a local definition of
guc_desc we have a chance to overflow stack, so avoid it.
Also, Chris abhors scatterlists :)

intel_{h,g}uc_init_fw selects correct firmware and then triggers it's
preparation (fetch + initial parsing).
This change separates out select steps, so those can be called by
the sanitize_options().
Then, during the init_fw(), we prepare the firmware if the firmware was
selected.

Currently fw->path values can represent one of three possible states:
1) NULL - device without the uC
2) '\0' - device with the uC but have no firmware
3) else - device with the uC and we have firmware
Second case is used only to WARN at a later stage.
We can WARN right away and merge cases 1 and 2.
Code can be even further simplified and common (HuC/GuC logic) happening
right before the fetch can be offloaded to the common function.

Instead of calling intel_guc_init() and intel_huc_init() one by one this
patch introduces intel_uc_init_fw() function that calls them both.
Called functions are renamed accordingly.
Trying to have subject_verb_object ordering and more descriptive names,
the intel_huc_init() and intel_guc_init() functions are renamed.
For guc_init():
* `intel_guc` is the subject, so those functions now take intel_guc
structure, instead of the dev_priv
* init is the verb
* fw is the object which better describes the function's role
huc_init() change follows the same reasoning.

The file fits better.
Additionally rename it to intel_uc_prepare_fw(), as the function does
more than simple fetch.
`obj` cleanup in the function is also fixed (i.e. removed). In the fail
scenario it was always 'put' but there's no possible flow that
initializes the obj properly and then goes to the fail label.

GuC historically has two "startup" functions called _init() and _setup()
Then HuC came with it's _init() and _load().
This commit renames intel_guc_setup() and intel_huc_load() to
*uc_init_hw() as they called from the i915_gem_init_hw().
The aim is to be consistent in that entry points called during
particular driver init phases (e.g. init_hw) are all suffixed by that
phase. When reading the leaf functions, it should be clear at what stage
during the driver load it is called and therefore what operations are
legal at that point.
Also, since the functions start with intel_guc and intel_huc they take
appropiate structure.

In order to ensure no missed interrupts we must first re-direct
the interrupts to GuC, and only then re-submit the requests to
be replayed after a GPU reset. Otherwise context switch can fire
before GuC has been set up to receive it triggering more hangs.

Driver needs to ensure that it doesn't mask the PM interrupts, which are
unmasked/needed by GuC firmware. For that, Driver maintains a bitmask of
interrupts to be kept unmasked, pm_intr_keep.
pm_intr_keep was determined across GuC load. GuC gets loaded in different
scenarios and it is not going to change the pm_intr_keep so this patch
moves its setup to intel_irq_init.
This patch fixes incorrect RPS masking leading to UP interrupts triggered
even when at cur_freq=max and inversly for Down interrupts.

Currently to establish whether GuC firmware has been loaded or
submission enabled (default DRM log level), one has to detect
the absence of the message saying that the load has been skipped
and infer the opposite.
It is better to log the fact GuC firmware has been loaded and/or
submission enabled explicitly to avoid any guesswork when looking
at the logs.

Move the GuC invalidation of its ggtt TLB to where we perform the ggtt
modification rather than proliferate it into all the callers of the
insert (which may or may not in fact have to do the insertion).
v2: Just do the guc invalidate unconditionally, (afaict) it has no impact
without the guc loaded on gen8+
v3: Conditionally invalidate the guc - just in case that register has
not been validated for other modes.

Since commit 4741da925fa3 ("drm/i915/guc: Assert that all GGTT offsets used
by the GuC are mappable"), we're asserting that GuC firmware is in the
GuC mappable range.
Except we're not pinning the object with bias, which means it's possible
to trigger this assert. Let's add a proper bias.

There are certain types of interrupts which Host can receive from GuC.
GuC ukernel sends an interrupt to Host for certain events, like for
example retrieve/consume the logs generated by ukernel.
This patch adds support to receive interrupts from GuC but currently
enables & partially handles only the interrupt sent by GuC ukernel.
Future patches will add support for handling other interrupt types.
v2:
- Use common low level routines for PM IER/IIR programming (Chris)
- Rename interrupt functions to gen9_xxx from gen8_xxx (Chris)
- Replace disabling of wake ref asserts with rpm get/put (Chris)
v3:
- Update comments for more clarity. (Tvrtko)
- Remove the masking of GuC interrupt, which was kept masked till the
start of bottom half, its not really needed as there is only a
single instance of work item & wq is ordered. (Tvrtko)
v4:
- Rebase.
- Rename guc_events to pm_guc_events so as to be indicative of the
register/control block it is associated with. (Chris)
- Add handling for back to back log buffer flush interrupts.
v5:
- Move the read & clearing of register, containing Guc2Host message
bits, outside the irq spinlock. (Tvrtko)
v6:
- Move the log buffer flush interrupt related stuff to the following
patch so as to do only generic bits in this patch. (Tvrtko)
- Rebase.
v7:
- Remove the interrupts_enabled check from gen9_guc_irq_handler, want to
process that last interrupt also before disabling the interrupt, sync
against the work queued by irq handler will be done by caller disabling
the interrupt.

So far there were 2 fields related to GuC logs in 'intel_guc' structure.
For the support of capturing GuC logs & storing them in a local buffer,
multiple new fields would have to be added. This warrants a separate
structure to contain the fields related to GuC logging state.
Added a new structure 'intel_guc_log' and instance of it inside
'intel_guc' structure.
v2: Rebase.

GuC Log buffer allocation was tied up with verbosity level module param
i915.guc_log_level. User would be given a provision to enable firmware
logging at runtime, through a host2guc action, and not necessarily during
Driver load time. But the address of log buffer can be passed only in
init params, at firmware load time, so GuC has to be reset and firmware
needs to be reloaded to pass the log buffer address at runtime.
To avoid reset of GuC & reload of firmware, allocation of log buffer will
be done always but logging would be enabled initially on GuC side based on
the value of module parameter guc_log_level.
v2: Update commit message to describe the constraint with allocation of
log buffer at runtime. (Tvrtko)
v3: Rebase.

i915.enable_guc_loading/submission=2 forces the usage of GuC.
For platforms that do not have a GuC, asking the kernel to use a GuC
should not result in an error state. Do extra checks to see if the
platform even has a GuC or not, regardless of the kernel parameter.
v2: Based on Rodrigo's patch and Paulo's suggestion(Paulo, Rodrigo)
v3: Correct the Indentation(Jani, Paulo)
v4: Added the blank line(Jani, Paulo)
v5 (from Paulo): Remove the extra blank line.

With the possibility of addition of many more number of rings in future,
the drm_i915_private structure could bloat as an array, of type
intel_engine_cs, is embedded inside it.
struct intel_engine_cs engine[I915_NUM_ENGINES];
Though this is still fine as generally there is only a single instance of
drm_i915_private structure used, but not all of the possible rings would be
enabled or active on most of the platforms. Some memory can be saved by
allocating intel_engine_cs structure only for the enabled/active engines.
Currently the engine/ring ID is kept static and dev_priv->engine[] is simply
indexed using the enums defined in intel_engine_id.
To save memory and continue using the static engine/ring IDs, 'engine' is
defined as an array of pointers.
struct intel_engine_cs *engine[I915_NUM_ENGINES];
dev_priv->engine[engine_ID] will be NULL for disabled engine instances.
There is a text size reduction of 928 bytes, from 1028200 to 1027272, for
i915.o file (but for i915.ko file text size remain same as 1193131 bytes).
v2:
- Remove the engine iterator field added in drm_i915_private structure,
instead pass a local iterator variable to the for_each_engine**
macros. (Chris)
- Do away with intel_engine_initialized() and instead directly use the
NULL pointer check on engine pointer. (Chris)
v3:
- Remove for_each_engine_id() macro, as the updated macro for_each_engine()
can be used in place of it. (Chris)
- Protect the access to Render engine Fault register with a NULL check, as
engine specific init is done later in Driver load sequence.
v4:
- Use !!dev_priv->engine[VCS] style for the engine check in getparam. (Chris)
- Kill the superfluous init_engine_lists().
v5:
- Cleanup the intel_engines_init() & intel_engines_setup(), with respect to
allocation of intel_engine_cs structure. (Chris)
v6:
- Rebase.
v7:
- Optimize the for_each_engine_masked() macro. (Chris)
- Change the type of 'iter' local variable to enum intel_engine_id. (Chris)
- Rebase.
v8: Rebase.
v9: Rebase.
v10:
- For index calculation use engine ID instead of pointer based arithmetic in
intel_engine_sync_index() as engine pointers are not contiguous now (Chris)
- For appropriateness, rename local enum variable 'iter' to 'id'. (Joonas)
- Use for_each_engine macro for cleanup in intel_engines_init() and remove
check for NULL engine pointer in cleanup() routines. (Joonas)
v11: Rebase.
