On PowerPC, the compiler will tag object files with whether they
use hard or soft float FP ABI and whether they use 64 or 128-bit
long double ABI. On systems with 64-bit long double ABI, a tag
will get emitted whenever a double is used, as on those systems
a long double is the same as a double. This will prevent linkage
as other files are being compiled with hard-float.
On ppc64, this code will never actually get used for the time
being, as the only currently existing hardware using it are the
Renoir APUs. Therefore, until this is testable and can be fixed
properly, at least make sure the build will not fail.

In current code we're essentially drawing the cursor on every pipe

scaling for src to dest rect, otherwise we'll get "double cursor" where
one cursor is incorrectly filtered and offset from the real position.
[How]
Without dedicated cursor planes on DCN we require at least one pipe
that matches the scaling of the current timing.
This is an optimization and workaround for the most common case where
the top-most plane is not scaled but the bottom-most plane is scaled.
Whenever a pipe has a parent pipe in the blending tree whose recout
fully contains the current pipe we can disable the pipe.
This only applies when the pipe is actually visible of course.

[WHY]
Two years ago the patch referenced by the Fixes tag stopped running
dp_verify_link_cap_with_retries during DP detection when the reason
for the detection was a short-pulse interrupt. This effectively meant
that we were no longer doing the verify_link_cap training on active
dongles when their SINK_COUNT changed from 0 to 1.
A year ago this was partly remedied with:
commit 80adaebd2d ("drm/amd/display: Don't skip link training for empty dongle")
This made sure that we trained the dongle on initial hotplug (without
connected downstream devices).
This is all fine and dandy if it weren't for the fact that there are
some dongles on the market that don't like link training when SINK_COUNT
is 0 These dongles will in fact indicate a SINK_COUNT of 0 immediately
after hotplug, even when a downstream device is connected, and then
trigger a shortpulse interrupt indicating a SINK_COUNT change to 1.
In order to play nicely we will need our policy to not link train an
active DP dongle when SINK_COUNT is 0 but ensure we train it when the
SINK_COUNT changes to 1.
[HOW]
Call dp_verify_link_cap_with_retries on detection even when the detection
is triggered from a short pulse interrupt.
With this change we can also revert this commit which we'll do in a separate
follow-up change:
commit 80adaebd2d ("drm/amd/display: Don't skip link training for empty dongle")

[Why]
There's a data race that can occur between when we update the
inbox write pointer vs when the memory for the command actually gets
flushed from the map to the framebuffer.
DMCUB can read stale or partially invalid data when this race occurs.
[How]
Before updating the write pointer we can read back all pending commands
to ensure that we stall for the writes to be flushed to framebuffer.
We don't need to worry about choosing HDP vs VM flush with this
mechanism.
Drop the dmub_srv_cmd_submit() while we're updating this to work
correctly since nothing was actually using this API and the caller
should be explicit about the API flow here - by doing this on execute
we can give some extra time for the flush to finish while
preparing other commands.
We should try to avoid writing single commands
because of this overhead.

happens, then DP display will never come back again.
Also, please note that dropping this disable_phy function

Whenever a connector on an MST network is attached, detached, or
undergoes a modeset, the DSC configs for each stream on that
topology will be recalculated. This can change their required
bandwidth, requiring a full reprogramming, as though a modeset
was performed, even if that stream did not change timing.
Therefore, whenever a crtc has drm_atomic_crtc_needs_modeset,
for each crtc that shares a MST topology with that stream and
supports DSC, add that crtc (and all affected connectors and
planes) to the atomic state and set mode_changed on its state
v2: Do this check only on Navi and before adding connectors
and planes on modesetting crtcs

[Why]
Cursor disappears for some SLS displays that are rotated 180
and 270 degrees. This occurs when there is no pipe split being
done ( ex. 3 or more displays ). The cursor calculations assume
pipe splitting is done so when it calculates the new cursor
position in hwss.set_cursor_position(), it is out-of-bounds so
it disables the cursor in hubp.set_cursor_position().
[How]
In non pipe split cases, calculate cursor using viewport size
( width or height ) instead of viewport size * 2 ( the two
because pipe splitting divides the rectangle into two ).

[Why]
When we rotate 270 in mixed SLS mode, the recouts occupy the
right side of the display. So all the recout_skip_v values
are relative to the left side of the display. This causes
adjust_vp_and_init_for_seamless_clip() to incorrectly increase
the data->viewport.height for that recout. The rotation looks
like the bottom half is duplicated twice.
[How]
recout.x values are being adjusted based on
stream->timing.h_border_left. Instead of using h_border_left,
use dst.x to represent the border. Shift dst.x by the amount of
stream->timing.h_border_left and set
stream->timing.h_border_left to 0. Do all the calculations
and then revert stream->timing.h_border_left and
stream->dst.x back to their original values.
When calculating pipe_ctx->plane_res.scl_data.h_active,
make sure to use the original stream->timing.h_border_left
value.

Up to 4 ODM memory pieces are required per ODM combine and cannot
overlap, i.e. each ODM "session" has to use its own memory pieces.
The ODM-memory mapping is currently broken for generic case.
The maximum number of memory pieces is ASIC-dependent, but it's always
big enough to satisfy maximum number of ODM combines. Memory pieces
are mapped as a bit-map, i.e. one memory piece corresponds to one bit.
The OPTC doing ODM needs to select memory pieces by setting the
corresponding bits, making sure there's no overlap with other OPTC
instances that might be doing ODM.
The current mapping works only for OPTC instance indexes smaller than
3. For instance indexes 3 and up it practically maps no ODM memory,
causing black, gray or white screen in display configs that include
ODM on OPTC instance 3 or up.
[how]
Statically map two unique ODM memory pieces for each OPTC instance
and piece them together when programming ODM combine mode.

Scratch registers are limited on the DMCUB and we have an expanding
list of state to track between driver and DMCUB.
[How]
Place shared state in cache window 6. The cache window size is aligned
to the size of the cache line on the DMCUB to make it easy to
invalidate.
The shared state is intended to be read only from driver side so
it's been marked as const.
The use of volatile is intentional. The memory for the shared firmware
state is memory mapped from the framebuffer memory. The DMCUB will
flush its cache after modifying the region. There's no way for x86
to known whether this data is stale or not so we want to intentionally
disable optimization to force the read at every access.

[Why]
Commands will be considered a stable ABI between driver and firmware.
Commands are also split between DC commands, DAL feature commands,
and VBIOS commands.
Commands are currently not designated to a specific ID and the enum
does not provide a stable ABI.
We currently group all of these into a single command type of 8-bits.
With the stable ABI consideration in mind it's not unreasonable to
run out of command IDs.
For cleaner separation and versioning split the commands into a main
type and a subtype.
[How]
For commands where performance matters (like reg sequences) these
are still considered main commands.
Sub commands will be split by ownership/feature.
Update existing command sequences to reflect new changes.
