Adsp fastrpc support for sm8750

[RFT PATCH v3 0/2] Adsp fastrpc support for sm8750

Posted by Alexey Klimov 2 months ago

Please test these changes therefore RFT tag. The fastrpc testing
application under linux doesn't work for me but I was told there
is a setup available somewhere in Qualcomm where this can be tested
(perhaps android?).

Changes from prev version:
- split patches into two: one adds mem node, second one
  adds fasrpc nodes.
- updated commit description.

(adding more Qcom folks to To: header, who asked to send this as soon
as possible)

I found time to compile and run the testing application. Currently it
seems to be untested under Linux (mainly strlcpy thingy and no manual
where files are expected to be found), there are also a lot of compilation
warnings.

========================================
Test Summary:
  Total tests run:    3
  Passed:             2
  Failed:             1
  Skipped:            0
========================================

RESULT: 1 test(s) FAILED

But the result is the same for CDSP (was it tested prior merging?).
The same results are for v75.

Adsprpcd works with audio_pd though. Maybe Qualcomm can help with this?
I don't think I will have enough time to debug this and narrow it down,
also very soon I will lose access to the device.

Best regards,
Alexey

Please open an issue in the repo with the above details so the FastRPC
folks can hopefully help sort this out

Good idea. Thanks. Done.
