Print the GuC captured error state register list (string names
and values) when gpu_coredump_state printout is invoked via
the i915 debugfs for flushing the gpu error-state that was
captured prior.
Since GuC could have reported multiple engine register dumps
in a single notification event, parse the captured data
(appearing as a stream of structures) to identify each dump as
a different 'engine-capture-group-output'.
Finally, for each 'engine-capture-group-output' that is found,
verify if the engine register dump corresponds to the
engine_coredump content that was previously populated by the
i915_gpu_coredump function. That function would have copied
the context's vma's including the bacth buffer during the
G2H-context-reset notification that occurred earlier. Perform
this verification check by comparing guc_id, lrca and engine-
instance obtained from the 'engine-capture-group-output' vs a
copy of that same info taken during i915_gpu_coredump. If
they match, then print those vma's as well (such as the batch
buffers).
NOTE: the output format was verified using the gem_exec_capture
IGT test.

Add a flags parameter through all of the coredump creation

level gpu_coredump event is triggered in response to
a GuC context reset notification.
Using that flag, ensure all coredump functions that
read or print mmio-register values related to work submission
or command-streamer engines are skipped and replaced with
a calls guc-capture module equivalent functions to retrieve
or print the register dump.
While here, split out display related register reading
and printing into its own function that is called agnostic
to whether GuC had triggered the reset.
For now, introduce an empty printing function that can
filled in on a subsequent patch just to handle formatting.

In the rare but possible scenario where we are in the midst of
multiple GuC error-capture (and engine reset) events and the
user also triggers a forced full GT reset or the internal watchdog
triggers the same, intel_guc_submission_reset_prepare's call
to flush_work(&guc->ct.requests.worker) can cause the G2H message
handler to trigger intel_guc_capture_store_snapshot upon
receiving new G2H error-capture notifications. This can happen
despite the prior call to disable_submission(guc);. However,
there's no race-free way for intel_guc_capture_store_snapshot to
know that we are in the midst of a reset. That said, we can never
dynamically allocate the output nodes in this handler. Thus, we
shall pre-allocate a fixed number of empty nodes up front (at the
time of ADS registration) that we can consume from or return to
an internal cached list of nodes.

- Upon the G2H Notify-Err-Capture event, parse through the
GuC Log Buffer (error-capture-subregion) and generate one or
more capture-nodes. A single node represents a single "engine-
instance-capture-dump" and contains at least 3 register lists:
global, engine-class and engine-instance. An internal link
list is maintained to store one or more nodes.
- Because the link-list node generation happen before the call
to i915_gpu_codedump, duplicate global and engine-class register
lists for each engine-instance register dump if we find
dependent-engine resets in a engine-capture-group.
- When i915_gpu_coredump calls into capture_engine, (in a
subsequent patch) we detach the matching node (guc-id,
LRCA, etc) from the link list above and attach it to
i915_gpu_coredump's intel_engine_coredump structure when have
matching LRCA/guc-id/engine-instance.
Additional notes to be aware of:
- GuC generates the error capture dump into the GuC log buffer but
this buffer is one big log buffer with 3 independent subregions
within it. Each subregion is populated with different content
and used in different ways and timings but all regions operate
behave as independent ring buffers. Each guc-log subregion
(general-logs, crash-dump and error- capture) has it's own
guc_log_buffer_state that contain independent read and write
pointers.

GuC log buffer regions for debug-log-events, crash-dumps and
error-state-capture are all part of a single bo allocation that
also includes the guc_log_buffer_state structures. Now that we
support it, increase the size allocation for error-capture.
Since the error-capture region is accessed at non-deterministic
times (as part of GuC triggered context reset) while debug-log-
events region is accessed as part of relay logging or during
debugfs triggered dumps, move the mapping and unmapping of the
shared buffer into intel_guc_log_create and intel_guc_log_destroy
so that it's always mapped throughout life of GuC operation.
Additionally, while here, update the guc log region layout
diagram to follow the order according to the enum definition
as per the GuC interface.
NOTE: A future effort to visit (part of baseline code) is that
buf_addr should be updated to be a io_sys_map and use the
io_sys_map wrapper functions to access the various GuC log
buffer regions.

Update GuC ADS size allocation to include space for

Then, populate GuC ADS with the lists of registers we want
GuC to report back to host on engine reset events. This list
should include global, engine-class and engine-instance
registers for every engine-class type on the current hardware.
Ensure we allocate a persistent store for the register lists
that are populated into ADS so that we don't need to allocate
memory during GT resets when GuC is reloaded and ADS population
happens again.
NOTE: Start with a sample static table of register lists to
layout the framework before adding real registers in subsequent
patch. This static register tables are a different format from
the ADS populated list.

Make the dbuf bandwidth min cdclk calculations match the spec
more closely. Supposedly the arbiter can only guarantee an equal
share of the total bandwidth of the slice to each active plane
on that slice. So we take the max bandwidth of any of the planes
on each slice and multiply that by the number of active planes
on the slice to get a worst case estimate on how much bandwidth
we require.

The current code also forgets to call intel_atomic_lock_global_state()
when other stuff besides the final min_cdlck changes in the state.
That means we may throw away data which actually has changed, and
thus we can't be at all sure what the code ends up doing during
subsequent commits. Do the write lock properly.

intel_bw_calc_min_cdclk() is entirely pointless. All it manages to do is
somehow conflate the per-pipe min cdclk with dbuf min cdclk. There is no
(at least documented) dbuf min cdclk limit on pre-skl so let's just get

There's really no need to maintain these total[] arrays to
track the size of each plane's ddb allocation. We just stick
the results straight into the crtc_state ddb tracking structures.
The main annoyance with all this is the mismatch between
wm_uv vs. ddb_y on pre-icl. If only the hw was consistent in
what it considers the primary source of information we could
avoid some of the uglyness. But since that is not the case
we need a bit of special casing for planar formats.

Handle the plane relative data rate in exactly the same
way as we already handle the real data rate. Ie. pre-calculate
it during intel_plane_atomic_check_with_state(), and assign/clear
it for the Y plane as needed. This should guarantee that the
tracking is 100% consistent, and makes me have to think less
when the same apporach is used by both types of data rate.
We might even want to consider replacing the relative
data rate with the real data rate entirely, but it's not
clear if that will produce less optimal plane ddb
allocations. So for now lets keep using the current approach.

Let's store the plane allocation in a manner which more closely
matches how the hw operates. That is, we store the packed/CbCr
ddb in one struct, and the Y ddb in another. Currently we're
storing packed/Y in one struct, CbCr in the other.
This also works pretty well for icl+ where the UV plane is
the main plane and the Y plane is subservient to it. Although
in this case we do not even use ddb_y as we do the ddb allocation

On platforms capable of allowing 8K (7680 x 4320) modes, pinning 2 or
more framebuffers/scanout buffers results in only one that is mappable/
fenceable. Therefore, pageflipping between these 2 FBs where only one
is mappable/fenceable creates latencies large enough to miss alternate
vblanks thereby producing less optimal framerate.
This mainly happens because when i915_gem_object_pin_to_display_plane()
is called to pin one of the FB objs, the associated vma is identified
as misplaced -- because there is no space for it in the aperture --
and therefore i915_vma_unbind() is called which unbinds and evicts it.
This misplaced vma gets subseqently pinned only when
i915_gem_object_ggtt_pin_ww() is called without PIN_MAPPABLE. This whole
thing results in a latency of ~10ms and happens every other repaint cycle.
Therefore, to fix this issue, we just ensure that the misplaced VMA
does not get evicted when we try to pin it with PIN_MAPPABLE -- by
returning early if the mappable/fenceable flag is not set.
Testcase:
Running Weston and weston-simple-egl on an Alderlake_S (ADLS) platform
with a 8K@60 mode results in only ~40 FPS (compared to ~59 FPS with
this patch). Since upstream Weston submits a frame ~7ms before the
next vblank, the latencies seen between atomic commit and flip event
are 7, 24 (7 + 16.66), 7, 24..... suggesting that it misses the
vblank every other frame.
Here is the ftrace snippet that shows the source of the ~10ms latency:
i915_gem_object_pin_to_display_plane() {
0.102 us | i915_gem_object_set_cache_level();
i915_gem_object_ggtt_pin_ww() {
0.390 us | i915_vma_instance();

For modern platforms the spec explicitly states that a

Let's extend that to all platforms. Supposedly there should
be no systems where this isn't true, and it'll allow us to:
- use the same code regardless of older vs. newer platform
- wm latencies already treat 0 as disabled, so this fits well
with other related code
- make it a bit more clear when SAGV is used vs. not
- avoid overflows from adding U32_MAX with a u16 wm0 latency value
which could cause us to miscalculate the SAGV watermarks on tgl+

logical to physical mapping is monotonically increasing - if the
application is not using the logical id.
Changing it for the previous platforms allows the media driver
implementation for the next ones (12.50 and above) to be the same,
checking the logical id. It should also not introduce any bug for the
old versions of userspace not checking the id.
The mapping added here is the complete map needed by XEHPSDV. Previous
