Hi, I'm trying to set up a Linux running on uvmm with a HW passthrough. I added `zynqmp_firmware` to my DTS (it was required for the device I'm trying to pass). However, Linux fails to add the device and I see: vm-1 | [ 1.772078] ledtrig-cpu: registered to indicate activity on CPUs vm-1 | VMM[guest]: No handler for SMC call: imm=0 a0=c200003f a1=3f ip=ffff800080026884 lr=ffff800080dcdb04 vm-1 | VMM[guest]: No handler for SMC call: imm=0 a0=c2000001 a1=0 ip=ffff800080026884 lr=ffff800080dcdb04 vm-1 | [ 1.805957] zynqmp_firmware firmware:zynqmp-firmware: probe with driver zynqmp_firmware failed with error -22 >From the traces I added, the failure is in `zynqmp_pm_get_api_version`. How do I add SMC handling? Best regards, Moshe _______________________________________________ l4-hackers mailing list -- [email protected] To unsubscribe send an email to [email protected]
