These patches enable HDCP2.x on machines MTL and above.
From MTL onwards CSME is spilt into GSC and CSC and now
we use GSC CS instead of MEI to talk to firmware to start
HDCP authentication
--v2
-Fixing some checkpatch changes which I forgot before sending
out the series

drm/i915/hdcp: Keep cp fw agonstic naming convention
drm/i915/hdcp: HDCP2.x Refactoring to agnotic cp f/w
drm/i915/hdcp: Refactor HDCP API structures
Suraj Kandpal (4):
drm/i915/gsc: Create GSC request submission mechanism
drm/i915/hdcp: Fill wired_cmd_in structures at a single place
drm/i915/mtl: Adding function to send command to GSC CS

HDCP and PXP will require a common function to allow it to
submit commands to the gsc cs. Also adding the gsc mtl header
that needs to be added on to the existing payloads of HDCP
and PXP.

As now we have more then one type of content protection
secrity firmware. Let change the i915_cp_fw_hdcp_interface.h
header naming convention to suit generic f/w type.
%s/MEI_/FW_
%s/mei_fw/cp_fw
%s/mei_dev/fw_dev
As interface to CP FW can be either a non i915 component or
i915 intergral component, change structure name Accordingly.

From: Suraj Kandpal @ 2022-12-13 7:01 UTC (permalink / raw)
To: intel-gfx; +Cc: Rodrigo Vivi, Tomas Winkler
From: Anshuman Gupta <anshuman.gupta@intel.com>
It requires to move intel specific HDCP API structures to
i915_cp_fw_hdcp_interface.h from driver/misc/mei/hdcp/mei_hdcp.h
so that any content protection fw interfaces can use these
structures.

From: Suraj Kandpal @ 2022-12-13 7:01 UTC (permalink / raw)
To: intel-gfx
Adding function that takes care of sending command to gsc cs. We start
of with allocation of memory for our command intel_hdcp_gsc_message that
contains gsc cs memory header as directed in specs followed by the
actual payload hdcp message that we want to send.
Spec states that we need to poll pending bit of response header around
20 times each try being 50ms apart hence adding that to current
gsc_msg_send function
Also we use the same function to take care of both sending and receiving
hence no separate function to get the response.

To: intel-gfx; +Cc: Rodrigo Vivi, Tomas Winkler
MTL uses GSC command streamer i.e gsc cs to send HDCP/PXP commands
to GSC f/w. It requires to keep hdcp display driver
agnostic to content protection f/w (ME/GSC fw) in the form of
i915_hdcp_fw_ops generic ops.
Adding HDCP GSC CS interface by leveraging the i915_hdcp_fw_ops generic
ops instead of I915_HDCP_COMPONENT as integral part of i915.
Adding checks to see if GSC is loaded and proxy is setup

If you want to make an hdcp interface naming agnostic to the
implementation details, why do we have to have "fw" in the naming, at
all?
Why is "cp" duplicated?
You're calling the file "i915 Content Protection Firmware High-bandwidth
Digital Content Protection Interface".
Why are the names *impossible* to pronounce?
I'd just make this "i915_hdcp_interface".
BR,
Jani.

Makes sense switching too i915_hdcp_interface and removing the duplicated
cp and fw

Why not drop the fw part here too? Just take a step further and make the
interface agnostic to being about firmware.
fw_dev -> hdcp_dev
enum cp_fw_ddi -> enum hdcp_port
enum cp_fw_tc -> enum hdcp_transcoder
enumerator values accordingly, with a sensible prefix.
For naming, try saying the names aloud, as if you were discussing this
on the phone with someone. "enum cp_fw_tc" just does not work.

Jani.

The function naming needs to match file name.
intel_hdcp_gsc.[ch] -> intel_hdcp_gsc_xxx().

I see what you are saying here but these lines end up getting duplicated both in
mei_hdcp.c and intel_gsc_hdcp.c so wanted to get these in a single place so if there is
a change in future I have the same place to change
if you have any other suggestion that would be great or else ill have to go back to duplicating these
lines in the aforementioned files

The previous patch adds the header and the declarations for the
functions and this one adds the definitions. They should go together,
hand in hand.

I don't have the time to figure this out for you, but massive amounts of
static inlines in headers really aren't the way to avoid duplicating
this much code. It's not an abstraction, it's just a clunky way to avoid
copy-paste.
Also, the header is no longer self-contained, i.e. it assumes whoever
includes it also includes a bunch of *other* kernel headers to work.
