[PATCH v12 0/6] drm/i915: Enable HDCP 1.4 and 2.2 on Gen12+

[Ramalingam C]

Enabling the HDCP1.4 and 2.2 on TGL by supporting the HW block movement
from DDI into transcoder.

v12:
  r-b and ack are collected.
  few review comments are addressed.

Ramalingam C (6):
  drm/i915: mei_hdcp: I915 sends ddi index as per ME FW
  drm: Move port definition back to i915 header
  drm: Extend I915 mei interface for transcoder info
  misc/mei/hdcp: Fill transcoder index in port info
  drm/i915/hdcp: update current transcoder into intel_hdcp
  drm/i915/hdcp: Enable HDCP 1.4 and 2.2 on Gen12+

[PATCH v12 1/6] drm/i915: mei_hdcp: I915 sends ddi index as per ME FW

[Ramalingam C]

I915 converts it's port value into ddi index defiend by ME FW
and pass it as a member of hdcp_port_data structure.

Hence expose the enum mei_fw_ddi to I915 through
i915_mei_interface.h.

In few I915 files I am seeing this format of copyright too. If this is not
right I could add (C) too.

[PATCH v12 2/6] drm: Move port definition back to i915 header

[Ramalingam C]

We dont need the definition of the enum port outside I915, anymore.
Hence move enum port definition into I915 driver itself.

v2:
  intel_display.h is included in intel_hdcp.h
v3:
  enum port is declared in headers.
v4:
  commit msg is rephrased.
v5:
  copyright year is updated [Tomas]

[PATCH v12 3/6] drm: Extend I915 mei interface for transcoder info

[Ramalingam C]

I915 needs to send the index of the transcoder as per ME FW.

To support this, define enum mei_fw_tc and add as a member into
the struct hdcp_port_data.

v2:
  Typo in commit msg is fixed [Shashank]
v3:
  kdoc is added for mei_fw_tc [Tomas]

[PATCH v12 4/6] misc/mei/hdcp: Fill transcoder index in port info

[Ramalingam C]

For gen12+ platform we need to pass the transcoder info
as part of the port info into ME FW.

This change fills the payload for ME FW from hdcp_port_data.

v2:
  Doc is enhanced for physical_port and attached_transcoder [Tomas]

[PATCH v12 5/6] drm/i915/hdcp: update current transcoder into intel_hdcp

[Ramalingam C]

On gen12+ platforms, HDCP HW is associated to the transcoder.
Hence on every modeset update associated transcoder into the
intel_hdcp of the port.

v2:
  s/trans/cpu_transcoder [Jani]
v3:
  comment is added for fw_ddi init for gen12+ [Shashank]
  only hdcp capable transcoder is translated into fw_tc [Shashank]
v4:
  fw_tc initialization is kept for modeset. [Tomas]
  few extra doc is added at port_data init [Tomas]
v5:
  Few comments are improvised [Tomas]

[PATCH v12 6/6] drm/i915/hdcp: Enable HDCP 1.4 and 2.2 on Gen12+

[Ramalingam C]

>From Gen12 onwards, HDCP HW block is implemented within transcoders.
Till Gen11 HDCP HW block was part of DDI.

Hence required changes in HW programming is handled here.

As ME FW needs the transcoder detail on which HDCP is enabled
on Gen12+ platform, we are populating the detail in hdcp_port_data.

v2:
  _MMIO_TRANS is used [Lucas and Daniel]
  platform check is moved into the caller [Lucas]
v3:
  platform check is moved into a macro [Shashank]
v4:
  Few optimizations in the coding [Shashank]
v5:
  Fixed alignment in macro definition in i915_reg.h [Shashank]
  unused variables "reg" is removed.
v6:
  Configuring the transcoder at compute_config.
  transcoder is used instead of pipe in macros.
  Rebased.
v7:
  transcoder is cached at intel_hdcp
  hdcp_port_data is configured with transcoder index asper ME FW.
v8:
  s/trans/cpu_transcoder
  s/tc/cpu_transcoder

Re: [PATCH v12 6/6] drm/i915/hdcp: Enable HDCP 1.4 and 2.2 on Gen12+

[Winkler, Tomas]

Now I'm reading this other patch about DG1 ' drm/i915/dg1: Initialize DDI ports for DG1' , is this condition still correct here?
Is the condition 'INTEL_GEN(dev_priv) >= 12' sufficient ?

Tomas,

Thanks for reviewing the patches and providing the Ack/R-bes.
As we discussed offline, we need your ACK for submitting mei_hdcp
patches through dinq(drm-intel-next-queued). Please provide the same.
