Trouble Activating SGX on BeagleBone Black with Kernel 5.10.168-ti-r64

General Discussion

I’m trying to activate the SGX (PowerVR) on my BeagleBone Black with the kernel version 5.10.168-ti. Here are the steps I’ve taken so far:

  1. Verifying the loaded module (pvrsrvkm):
    The command shows that the module is loaded, which is a positive sign:lsmod | grep pvr pvrsrvkm
pvrsrvkm 368640 0
  1. Checking system messages:
    The command shows that the kernel has detected and initialized the driver without any apparent errors:dmesg | grep -i pvr pvr
[   73.563532] pvrsrvkm: loading out-of-tree module taints kernel.
[   74.023666] [drm] Initialized pvr 1.17.4948957 20110701 for 56000000.gpu on minor 1
  1. Attempting to start the rc.pvr service:
    When I try to start the service using the command , I encounter the following error:/etc/init.d/rc.pvr start
PVR:(Error): PVRSRVBridgeCall: Failed to access device.
PVR:(Error): OpenServices: PVRSRVBridgeCall failed.
PVR:(Error): PVRSRVInitSrvConnect: PVRSRVConnect failed.
SrvInit: PVRSRVInitSrvConnect failed (4)
/usr/bin/pvrsrvctl: SrvInit failed (already initialized?) (err=PVRSRV_ERROR_INIT_FAILURE)

Has anyone encountered this issue, or can provide guidance on how to successfully activate SGX on this kernel version?

activate SGX on BeagleBone Black with Kernel 5.10.168-ti-r64, and ensure SGX support is enabled in the kernel configuration. you may need to load the SGX driver and potentially apply custom patches if it’s not natively supported. check forums for specific kernel patches or instructions related to SGX on your board.

I looked at that a long time ago, it appears to be a dinosaur.
