<content type='text'>
[why]
Virtual encoders &amp; hwss were grouped in a separate directory,
not aligned with dio and link component structure.

[how]
Moved virtual_link_encoder and virtual_stream_encoder to dc/dio/virtual/.
Moved virtual_link_hwss to dc/link/hwss/ and renamed to link_hwss_virtual.
Removed dc/virtual/ directory.
Updated all includes and build files (Makefiles)

[Why]
dml2 folder contains all logic for all versions of DML2
This is currently DML2.0 and DML2.1.
Rename dml2 to dml2_0 folder to reflect this better (dml2_0
for DML2.0).

[How]
Rename dml2 to dml2_0 folder and update dml2 references to
use dml2_0 folder.

<title>drm/amd/display: Add Component To Handle Bounding Box Values and IP Caps</title>
<updated>2025-08-29T14:14:02+00:00</updated>

<id>cf49a454e16675fad59c1080f909a7e51192a494</id>
<content type='text'>
[Why]
Bounding box values can be stored in multiple locations. (e.g. PMFW, VBIOS, DMUB).
The source and interpretation of these values can vary with DCN revision
so there should be a component that can gather these values and translate
them accordingly

[How]
Have component start with the statically defined values as a base.
Then update them as needed with DCN-specific logic
Guard this component with FPU flags since values need to be in float point.

<title>drm/amd/display: HDCP Locality check using DMUB Fused IO</title>
<updated>2025-04-07T22:01:07+00:00</updated>

<id>ce801e5d6c1bac228bf10f75e8bede4285c58282</id>
<content type='text'>
[Why]
HDCP locality check has strict timing requirements, currently broken
due to reliance on msleep which does not guarantee accuracy.
The PR moves the write-poll-read sequence into DMUB using new generic
Fused IO interface, where the timing accuracy is greatly improved.
New flow is enabled using DCN resource capability bit (none for now),
or using a debug flag.

[How]
* Extended mod_hdcp_config with new function for requesting DMUB
to execute a sequence of fused I2C/AUX commands and synchronously
wait until an outbox reply arrives or a timeout expires.
* If the timeout expires, send an abort to DMUB.
* Update HDCP to use the DMUB for locality check if supported.
* Add DC_HDCP_LC_FORCE_FW_ENABLE and DC_HDCP_LC_ENABLE_SW_FALLBACK.
* Make the first enable new flow regardless of resource capabilities.
* Make the second enable fallback to old SW flow.
* Clean up makefile source file listings for easier updates.
