Package: linux-image-amd64
Severity: wishlist
Since Linux 5.6, CONFIG_INTEL_MEI_HDCP is available which allows to use HDCP 2.2 with i915 graphics.
The HDCP support for AMD GPUs is already enabled (CONFIG_DRM_AMD_DC_HDCP=y).
Having this available in the kernel config would improve support for various video streaming
services and enable full use of package intel-hdcp. Its README claims CONFIG_INTEL_MEI_TXE must be
available as well, which might be an outdated information.
Please enable both CONFIG_INTEL_MEI_HDCP and CONFIG_INTEL_MEI_TXE as modules.

Hi Bastian,
Were you able to verify that enabling those two as modules make it
work?
The time for changes for bullseye is thight, so would like to hear a
confirmation, the needed changed could be tested and confirmed to
work.
Many thanks in advance already,
Regards,
Salvatore

I honestly do not know how to check from userspace. xrandr has a Content Protection flag that is

responsible for enabling/indicating HDCP usage. It works but I cannot verify it to be HDCP v2.2
(v1.4 works without those configs). libhdcpsdk has a HDCPSetProtectionLevel but I do not have the
time right now to write a test program.

Running 'xrandr --verbose' from Xorg should give you the supported
HDCP Content Type. If that reports "HDCP Type1" then support for HDCP 2.2 is
enabled.

HDCP Content Type. If that reports "HDCP Type1" then support for HDCP 2.2 is
enabled.

Works as expected. Enabling the two configs is sufficient.

Hi Vincent,
As it was verified to work and it adds important additional hardware
support, then yes please.
I just find at this stage the part very important, we should try to
enable additional HW support only if we have some verification that it
adds value for the users, this is why I mentioned it last time.

Salvatore
