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.

Alan: To be honest, code function names + responsibilities lack proper hierarchy - doens't look quite right from my perspective for readability / scalability.
In my opinion, we create a separate functions for load_fw vs heci_packet. But have a common utility function for the actual sending to HW (engine->emit_flush)
and waiting with a timeout (i915_request_wait). We know heci_packet will in future be used by PXP and potentially across both concurrently.
Then we mirror the same thing for general heci load (thus also allowing differentiated debug messages):
intel_gsc_engine_send_loadfw
| (allocate the request, use the gsc-ce).
|---> emit_gsc_heci_pkt (fill up the send-heci-pkt cmd)
|---> submit_to_gsc_fw(req, ... timeout)
intel_gsc_engine_send_hecipkt
| (allocate the request, use the gsc-ce).
| (we could even potentially create the MTL CS HEADER here itself
| since the GSC-CS memory header isnt an entity of the caller
| subsystem such as hdcp or pxp, but rather is the entity of the
| (GSC) command-streamer param, so bring it into intel_gsc_fw file)
|---> emit_gsc_fw_load (fill up the fw load cmd)
|---> submit_to_gsc_fw(req, ... timeout)
* intel_gsc_engine_send_hecipkt common to >1 caller-subsystems
Additionally, one last thing might be to move only sets of functions into separate files with common helpers:
intel_gsc_fw.c : all the firmware loading related functions
intel_gsc_heci.c : all the heci command packet sending related functions (here is where we can add the GSC-CS memory header population and in future, the host-session-id
allocation for PXP).
intel_gsc_cs_helper : for the submit_to_gsc_fw and other common functions to both fw-loading and heci-packet sending.

Wouldn’t that be a lot of repeated code just to have a little more readability.
Maybe just add some comments as to what the functions do that should avoid

Idk if filling the header in this function itself would be the best, we can have a common function defined here
If required to fill the header but I would like to give both hdcp pxp a little freedom as to when they fill
this up.

Alan: btw, from the internal specs, if i understand it correctly, at the heci command packet level, this ought to be called "heci_client_id", not "gsc_address".

This patch now *deletes* the file. The next patch adds it back. Please
be more careful before sending.
Please check that all commits build before sending, run something like:
$ git rebase -i $tip --exec="make -j8"
This should be standard practice for all contributions.
BR,
Jani.

From: Anshuman Gupta <anshuman.gupta@intel.com>
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_/HDCP_
%s/mei_dev/hdcp_dev
As interface to CP FW can be either a non i915 component or
i915 intergral component, change structure name Accordingly.

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.

Add 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.

Alan: See my review comment on patch #1 - i believe most of this function above (intel_hdcp_gsc_msg_send)
could go into a common intel_gsc_engine_send_hecipkt function (in a new gsc-heci specific file, i.e. intel_gsc_heci.c)
that lives in the uc/gsc domain, not here in display. In fact the "struct intel_hdcp_gsc_message" also also be renamed
to be "struct intel_gsc_heci_pkt_info" and its definition moved over to (and included from) a header in the uc/gsc domain.
I believe it make sense for the caller to allocate the objects but the common header to have the structure definition and
the common function can do the cmd-prep, submission, waiting (and eventually checking of pending-bit).

I can move a lot of these functions to intel_gsc_fw.c
But I still don’t see the merit in adding more functions and files in just for more readability

Replying back after the offline meeting. So just to recap, my concerns include:
1. In hindsight, "readability" wasn't the correct term - i wanted to highlight the importance of how we organize the code hierarchy in accordance to the HW architecture so
that if changes in future hw or workarounds are required, we can eventually can maintain as much common-hw changes (agnostic to the internals of the heci-pkt) to a single
layer
2. Also, with regards to the reviewing process, we know that 3 sets of series are emerging over these coming weeks - gsc-sw-proxy, hdcp and pxp and all of them are going to be
adding patches for the mtl-gsc-mem-header structure population and the gsc-cs heci-load-pkt command submission. So it might be better for reviewers and ourselves if we can
maintain roughly the same function names/locations/responsibilities as these coming series add-on or modify those common codes/..
So as per this mornings, meeting that included Daniele, here is the summary proposal we agreed on - that adds some common helpers while keeping other common-hw resposibilities
as caller-handled (to cater for different e2e flows):
Create new common utility files with common functions:
1. gt/uc/intel_gsc_uc_heci_cmd_submit.h
1. define the mtl-mem-header as per now
2. Add the "host-session-handle-rules" we need to add BIT-MASKS for different usages for host_session_handle
uint64_t: (details of these bitmasks can be discussed thru review but here is what we concluded from mtg:
- BITMASKS [63...60] (0000 = hdcp, 00001 = pxp-single, (downstrm-only 00002 = pxp-multi), future...)
- caller must obey - verified by intel_gsc_uc_heci_cmd_emit_mtl_memhdr
- BITMASKS [59...50] (caller-mask)
- caller can fill this with anything it wants
- PXP would use this arb-session-rolling-counter, hdcp could use this for pipe differentiation
- BITMASKS [49...00] (randomly generated number)
- caller to fill this with anything it wants but really should be randomly generated
* must be unique per calling process + usage.
2. gt/uc/intel_gsc_uc_heci_cmd_submit.c
a. helper -- intel_gsc_uc_heci_cmd_emit_mtl_memhdr
params:
- virt-ptr to the mem header (pinned object)
- message_address_type
- params = size
- flags (after
- host-session = (has to verify in the rules of "@HSH)" based on message_address_type)
b. common = intel_gsc_uc_heci_cmd_submit_packet
(does the same thing as the current code but an independant function,
NOT overloading the gsc-load or heci-submission based on "pkt" as current patch)
- mostly the same code
- caller will do mtl-header pre-population using the helper 2-a
- takes in the objects (from caller), creates the request internally
- no pending bit management - caller handles that the checking of "pending-bit" + "gsc_message_handle" echo
c. for PXP arb session - dont use priveleged instruction, use global instruction.
- need to verify if this works - testing was done to use GGTT like multi-session - expected to work.
- if works, we can use the same 2-b submission helper

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
--v3
-abstract DISPLAY_VER check [Jani]
