drm/amd/display: move location of dmub_srv.h file

2020-05-05T17:12:33+00:00

[Why]
Make a separation of what belongs in the differen dmub
headers

dmub_srv.h is for exposing dmub srv interface to rest of
driver.

other headers inside dmub/inc exposes cmds and definitions
that are owned by the firmware

[How]
keep firmware owned definitions in dmub/inc

move stuff that is purely driver interface headers to dmub/
since those are interface calls that are defined for rest of
driver to use

drm/amd/display: Pass command instead of header into DMUB service

2020-04-28T20:19:05+00:00

[Why]
We read memory that we shouldn't be touching if the struct isn't
a full union dmub_rb_cmd.

[How]
Fix up all the callers and functions that take in the dmub_cmd_header
to use the dmub_rb_cmd instead.

drm/amd/display: Fix DMUB meta offset for new load method

2020-04-28T20:17:17+00:00

[Why]
The new metadata offset is located at the end of the firmware binary
without any additional padding.

Firmware state is currently larger than 1024 bytes so new firmware state
will hang when trying to access any data above 1024 bytes.

[How]
Specify the correct offset based on legacy vs new loading method.

drm/amd/display: Various fixes for PSR on DMCUB

2020-04-22T22:11:48+00:00

[Why]
- Driver does not recognize new definitions of psr states.
- Internal tool is required for checking if psr is active.

[How]
- Parse psr state correctly so that driver will recognize psr state.
- Add visual confirmation that psr is active using existing mechanisms.

drm/amd/display: Unify psr feature flags

2020-04-22T22:11:47+00:00

[Why]
As it stands, psr has feature flags in dm, stream, and link. Most are
not defined well enough, and different dm layers have different uses for
these same flags.

[How]
We define a new structure called psr_settings in dc_link that will hold
the following psr feature flags:

psr_feature_enable - psr is supported
psr_allow_active - psr is currently active
psr_version - internal psr version supported
psr_frame_capture_indication_req
psr_sdp_transmit_line_num_deadline
The last two flags were moved out of the power module
for the purposes of consolidating psr flags.
Their use is already well-defined.

Psr caps reported by sink will also be stored in dc_link,
in dpcd_caps.psr_caps.

drm/amd/display: Make DMCUB bss/data firmware blob optional

2020-04-09T14:43:17+00:00

[Why]
By moving everything out of .data into the other regions we can drop
the requirement for the second blob and unify it all into the inst/const
blob.

[How]
We need to still support the blob being there and not being there for
backwards compatibility.

Look for the DMCUB metadata section in the end of the inst/const blob
instead of bss/data is missing.

Clear CW2 if we don't have the data blob so we don't hang when
transitioning between data blob/blobless firmwares.

Don't memcpy the blob into CW2 region if it doesn't exist.
