This patch series attempts to add support for a DP-HDMI2.1 Protocol
Convertor. The VESA spec for the HDMI2.1 PCON are proposed in Errata
E5 to DisplayPort_v2.0:
https://vesa.org/join-vesamemberships/member-downloads/?action=stamp&fileid=42299
The details are mentioned in:
VESA DP-to-HDMI PCON Specification Standalone Document
https://groups.vesa.org/wg/DP/document/15651
This series starts with adding support for FRL (Fixed Rate Link)
Training between the PCON and HDMI2.1 sink.
As per HDMI2.1 specification, a new data-channel or lane is added in
FRL mode, by repurposing the TMDS clock Channel. Through FRL, higher
bit-rate can be supported, ie. up to 12 Gbps/lane (48 Gbps over 4
lanes).
With these patches, the HDMI2.1 PCON can be configured to achieve FRL
training based on the maximum FRL rate supported by the panel, source
and the PCON.
The approach is to add the support for FRL training between PCON and
HDMI2.1 sink and gradually add other blocks for supporting higher
resolutions and other HDMI2.1 features, that can be supported by pcon
for the sources that do not natively support HDMI2.1.
This is done before the DP Link training between the source and PCON
is started. In case of FRL training is not achieved, the PCON will
work in the regular TMDS mode, without HDMI2.1 feature support.
Any interruption in FRL training between the PCON and HDMI2.1 sink is
notified through IRQ_HPD. On receiving the IRQ_HPD the concerned DPCD
registers are read and FRL training is re-attempted.
Currently, we have tested the FRL training and are able to enable 4K
display with TGL Platform + Realtek PCON RTD2173 with HDMI2.1 supporting
panel.
v2: Addressed review comments and re-organized patches as suggested in
comments on RFC patches.
v3: Addressed review comments on previous version.
v4: Added support for RGB->YCBCR conversion through PCON
v5: Addressed review comments on previous version.

The HDMI2.1 extends HFVSDB (HDMI Forum Vendor Specific
Data block) to have fields related to newly defined methods of FRL
(Fixed Rate Link) levels, number of lanes supported, DSC Color bit
depth, VRR min/max, FVA (Fast Vactive), ALLM etc.
This patch adds the new HFVSDB fields that are required for
HDMI2.1.

This patch parses HFVSDB fields for DSC1.2 capabilities of an
HDMI2.1 sink. These fields are required by a source to understand the
DSC capability of the sink, to set appropriate PPS parameters,
before transmitting compressed data stream.
v2: Addressed following issues as suggested by Uma Shankar:
-Added a new struct for hdmi dsc cap

To: intel-gfx; +Cc: airlied, dri-devel
This patch parses HFVSDB fields for DSC1.2 capabilities of an
HDMI2.1 sink. These fields are required by a source to understand the
DSC capability of the sink, to set appropriate PPS parameters,
before transmitting compressed data stream.
v2: Addressed following issues as suggested by Uma Shankar:
-Added a new struct for hdmi dsc cap
-Fixed bugs in macros usage.

This patch adds support for configuring a PCON device,
connected as a DP branched device to enable FRL Link training
with a HDMI2.1 + sink.
v2: Fixed typos and addressed other review comments from Uma Shankar.
-changed the commit message for better clarity (Uma Shankar)
-removed unnecessary argument supplied to a drm helper function.
-fixed return value for max frl read from pcon.
v3: Removed DPCD 0x3035 for MAX Sink FRL b/w as per new version of spec.

To: intel-gfx; +Cc: airlied, dri-devel
This patch adds support for configuring a PCON device,
connected as a DP branched device to enable FRL Link training
with a HDMI2.1 + sink.
v2: Fixed typos and addressed other review comments from Uma Shankar.
-changed the commit message for better clarity (Uma Shankar)
-removed unnecessary argument supplied to a drm helper function.
-fixed return value for max frl read from pcon.
v3: Removed DPCD 0x3035 for MAX Sink FRL b/w as per new version of spec.

* [PATCH v5 05/15] drm/dp_helper: Add support for link failure detection
2020-12-16 5:31 ` [Intel-gfx] " Ankit Nautiyal

Cc: swati2.sharma, airlied, vandita.kulkarni, uma.shankar, dri-devel
From: Swati Sharma <swati2.sharma@intel.com>
There are specific DPCDs defined for detecting link failures between
the PCON and HDMI sink and check the link status. In case of link
failure, PCON will communicate the same using an IRQ_HPD to source.
HDMI sink would have indicated the same to PCON using SCDC interrupt
mechanism. While source can always read final HDMI sink's status using
I2C over AUX, it is easier and faster to read the PCONs already read
HDMI sink status registers.
This patch adds the DPCDs required for link failure detection and
provide a helper function for printing error count/lane which might
help in debugging the link failure issues.
v2: Addressed comments from Uma Shankar:
-rephrased the commit message, as per the code.
-fixed styling issues
-added documentation for the helper function.

* [Intel-gfx] [PATCH v5 05/15] drm/dp_helper: Add support for link failure detection

From: Swati Sharma <swati2.sharma@intel.com>
There are specific DPCDs defined for detecting link failures between
the PCON and HDMI sink and check the link status. In case of link
failure, PCON will communicate the same using an IRQ_HPD to source.
HDMI sink would have indicated the same to PCON using SCDC interrupt
mechanism. While source can always read final HDMI sink's status using
I2C over AUX, it is easier and faster to read the PCONs already read
HDMI sink status registers.
This patch adds the DPCDs required for link failure detection and
provide a helper function for printing error count/lane which might
help in debugging the link failure issues.
v2: Addressed comments from Uma Shankar:
-rephrased the commit message, as per the code.
-fixed styling issues
-added documentation for the helper function.

This patch adds registers for getting DSC encoder capability for
a HDMI2.1 PCon. It also addes helper functions to configure
DSC between the PCON and HDMI2.1 sink.
v2: Corrected offset for DSC encoder bpc and minor changes.
Also added helper functions for getting pcon dsc encoder capabilities
as suggested by Uma Shankar.
v3: Only setting the DSC bits for the Protocol Convertor control
registers, avoiding overwritining color conversion bits.

To: intel-gfx; +Cc: airlied, dri-devel
This patch adds registers for getting DSC encoder capability for
a HDMI2.1 PCon. It also addes helper functions to configure
DSC between the PCON and HDMI2.1 sink.
v2: Corrected offset for DSC encoder bpc and minor changes.
Also added helper functions for getting pcon dsc encoder capabilities
as suggested by Uma Shankar.
v3: Only setting the DSC bits for the Protocol Convertor control
registers, avoiding overwritining color conversion bits.

DP Specification for DP2.0 to HDMI2.1 Pcon specifies support for conversion
of colorspace from RGB to YCbCr.
https://groups.vesa.org/wg/DP/document/previewpdf/15651
This patch adds the relavant registers and helper functions to
get the capability and set the color conversion bits for rgb->ycbcr
conversion through PCON.
v2: As suggested in review comments:
-Fixed bug in the check condition in a drm_helper as reported by
Dan Carpenter and Kernel test robot. (Dan Carepenter)
-Modified the color-conversion cap helper function, to accomodate
BT709 and BT2020 colorspace. (Uma Shankar)
-Added spec details for the new cap for color conversion. (Uma Shankar)

DP Specification for DP2.0 to HDMI2.1 Pcon specifies support for conversion
of colorspace from RGB to YCbCr.
https://groups.vesa.org/wg/DP/document/previewpdf/15651
This patch adds the relavant registers and helper functions to
get the capability and set the color conversion bits for rgb->ycbcr
conversion through PCON.
v2: As suggested in review comments:
-Fixed bug in the check condition in a drm_helper as reported by
Dan Carpenter and Kernel test robot. (Dan Carepenter)
-Modified the color-conversion cap helper function, to accomodate
BT709 and BT2020 colorspace. (Uma Shankar)
-Added spec details for the new cap for color conversion. (Uma Shankar)

HDMI2.1 PCON advertises Max FRL bandwidth supported by the PCON.
This patch captures this in dfp cap structure in intel_dp and uses
this to prune connector modes that cannot be supported by the PCON
and FRL bandwidth.
v2: Addressed review comments from Uma Shankar:
-tweaked the comparison of target bw and pcon frl bw to avoid roundup errors.
-minor modification of field names and comments.

* [PATCH v5 09/15] drm/i915: Add support for starting FRL training for HDMI2.1 via PCON

This patch adds functions to start FRL training for an HDMI2.1 sink,
connected via a PCON as a DP branch device.
This patch also adds a new structure for storing frl training related
data, when FRL training is completed.
v2: As suggested by Uma Shankar:
-renamed couple of variables for better clarity
-tweaked the macros used for correct semantics for true/false
-fixed other styling issues.
v3: Completed the TODO for condition for going to FRL mode.
Modified the condition to determine the required FRL b/w
based only on the Pcon and Sink's max FRL values.
Moved the frl structure initialization to intel_dp_init_connector().
v4: Fixed typo in initialization of frl structure.
v5: Always use FRL if its possible, instead of enabling only for
higher modes as done in v3.

* [Intel-gfx] [PATCH v5 09/15] drm/i915: Add support for starting FRL training for HDMI2.1 via PCON
@ 2020-12-16 5:31 ` Ankit Nautiyal

To: intel-gfx; +Cc: airlied, dri-devel
This patch adds functions to start FRL training for an HDMI2.1 sink,
connected via a PCON as a DP branch device.
This patch also adds a new structure for storing frl training related
data, when FRL training is completed.
v2: As suggested by Uma Shankar:
-renamed couple of variables for better clarity
-tweaked the macros used for correct semantics for true/false
-fixed other styling issues.
v3: Completed the TODO for condition for going to FRL mode.
Modified the condition to determine the required FRL b/w
based only on the Pcon and Sink's max FRL values.
Moved the frl structure initialization to intel_dp_init_connector().
v4: Fixed typo in initialization of frl structure.
v5: Always use FRL if its possible, instead of enabling only for
higher modes as done in v3.

This patch calls functions to check FRL training requirements
for an HDMI2.1 sink, when connected through PCON.
The call is made before the DP link training. In case FRL is not
required or failure during FRL training, the TMDS mode is selected
for the pcon.
v2: moved check_frl_training() just after FEC READY, before
starting DP link training.
v3: rebase

In this patch enables support for detecting link failures between
PCON and HDMI sink in i915 driver. HDMI link loss indication to
upstream DP source is indicated via IRQ_HPD. This is followed by
reading of HDMI link configuration status (HDMI_TX_LINK_ACTIVE_STATUS).
If the PCON → HDMI 2.1 link status is off; reinitiate frl link
training to recover. Also, report HDMI FRL link error count range for
each individual FRL active lane is indicated by
DOWNSTREAM_HDMI_ERROR_STATUS_LN registers.
v2: Checked for dpcd read and write failures and added debug message.
(Uma Shankar)
v3: Rearranged code to re-start FRL link training or fall back to
TMDS mode.
v4: Resused function to check frl which inturn restarts FRL and
fallback to TMDS mode.

This patch adds support to read and store the DSC capabilities of the
HDMI2.1 PCon encoder. It also adds a new field to store these caps,
The caps are read during dfp update and can later be used to get the
PPS parameters for PCON-HDMI2.1 sink pair. Which inturn will be used
to take a call to override the existing PPS-metadata, by either
writing the entire new PPS metadata, or by writing only the
PPS override parameters.
v2: Restructured the code to read all capability DPCDs at once and store
in an array in intel_dp structure.
v3: rebase

* [PATCH v5 13/15] drm/i915: Add helper functions for calculating DSC parameters for HDMI2.1

The DP-HDMI2.1 PCON spec provides way for a source to set PPS
parameters: slice height, slice width and bits_per_pixel, based on
the HDMI2.1 sink capabilities. The DSC encoder of the PCON will
respect these parameters, while preparing the 128 byte PPS.
This patch adds helper functions to calculate these PPS paremeters as
per the HDMI2.1 specification.
v2: Addressed review comments given by Uma Shankar:
-added documentation for functions
-fixed typos and errors

* [Intel-gfx] [PATCH v5 13/15] drm/i915: Add helper functions for calculating DSC parameters for HDMI2.1

To: intel-gfx; +Cc: airlied, dri-devel
The DP-HDMI2.1 PCON spec provides way for a source to set PPS
parameters: slice height, slice width and bits_per_pixel, based on
the HDMI2.1 sink capabilities. The DSC encoder of the PCON will
respect these parameters, while preparing the 128 byte PPS.
This patch adds helper functions to calculate these PPS paremeters as
per the HDMI2.1 specification.
v2: Addressed review comments given by Uma Shankar:
-added documentation for functions
-fixed typos and errors

* [PATCH v5 14/15] drm/i915/display: Configure PCON for DSC1.1 to DSC1.2 encoding
2020-12-16 5:31 ` [Intel-gfx] " Ankit Nautiyal

Cc: swati2.sharma, airlied, vandita.kulkarni, uma.shankar, dri-devel
When a source supporting DSC1.1 is connected to DSC1.2 HDMI2.1 sink
via DP HDMI2.1 PCON, the PCON can be configured to decode the
DSC1.1 compressed stream and encode to DSC1.2. It then sends the
DSC1.2 compressed stream to the HDMI2.1 sink.
This patch configures the PCON for DSC1.1 to DSC1.2 encoding, based
on the PCON's DSC encoder capablities and HDMI2.1 sink's DSC decoder
capabilities.
v2: Addressed review comments from Uma Shankar:
-fixed the error in packing pps parameter values
-added check for pcon in the pcon related function
-appended display in commit message
v3: Only consider non-zero DSC FRL b/w for determining max FRL b/w
supported by sink.

* [Intel-gfx] [PATCH v5 14/15] drm/i915/display: Configure PCON for DSC1.1 to DSC1.2 encoding
@ 2020-12-16 5:31 ` Ankit Nautiyal
0 siblings, 0 replies; 46+ messages in thread
From: Ankit Nautiyal @ 2020-12-16 5:31 UTC (permalink / raw)
To: intel-gfx; +Cc: airlied, dri-devel
When a source supporting DSC1.1 is connected to DSC1.2 HDMI2.1 sink
via DP HDMI2.1 PCON, the PCON can be configured to decode the
DSC1.1 compressed stream and encode to DSC1.2. It then sends the
DSC1.2 compressed stream to the HDMI2.1 sink.
This patch configures the PCON for DSC1.1 to DSC1.2 encoding, based
on the PCON's DSC encoder capablities and HDMI2.1 sink's DSC decoder
capabilities.
v2: Addressed review comments from Uma Shankar:
-fixed the error in packing pps parameter values
-added check for pcon in the pcon related function
-appended display in commit message
v3: Only consider non-zero DSC FRL b/w for determining max FRL b/w
supported by sink.

If PCON has capability to convert RGB->YUV colorspace and also
to 444->420 downsampling then for any YUV420 only mode, we can
let the PCON do all the conversion.
v2: As suggested by Uma Shankar, considered case for colorspace
BT709 and BT2020, and default to BT609. Also appended dir
'display' in commit message.

* [Intel-gfx] [PATCH v5 15/15] drm/i915/display: Let PCON convert from RGB to YUV if it can
@ 2020-12-16 5:31 ` Ankit Nautiyal
0 siblings, 0 replies; 46+ messages in thread
From: Ankit Nautiyal @ 2020-12-16 5:31 UTC (permalink / raw)
To: intel-gfx; +Cc: airlied, dri-devel
If PCON has capability to convert RGB->YUV colorspace and also
to 444->420 downsampling then for any YUV420 only mode, we can
let the PCON do all the conversion.
v2: As suggested by Uma Shankar, considered case for colorspace
BT709 and BT2020, and default to BT609. Also appended dir
'display' in commit message.

If PCON has capability to convert RGB->YUV colorspace and also
to 444->420 downsampling then for any YUV420 only mode, we can
let the PCON do all the conversion.
v2: As suggested by Uma Shankar, considered case for colorspace
BT709 and BT2020, and default to BT609. Also appended dir
'display' in commit message.
v3: Fixed typo in condition for printing one of the error msg.

One concern I have here is what will happen if pcon returns 0 here. From SOC we will be sending
BT2020 RGB, so we expect it to be able to support this conversion. So ideally this should not be optional
but kind of mandatory for pcon to support.

Just initialize tmp to 0 and drop this else.

Next line should match the parenthesis, seems off.

One concern I have here is what will happen if pcon returns 0 here. From SOC we will be sending
BT2020 RGB, so we expect it to be able to support this conversion. So ideally this should not be optional
but kind of mandatory for pcon to support.

Just initialize tmp to 0 and drop this else.

Here also, match the parenthesis.
