Sorry for the late reply. It should work, I think. But currently (in Plucky) we’re missing Venus firmware:
[ 5.947627] qcom-venus aa00000.video-codec: Adding to iommu group 18
[ 5.949637] qcom-venus aa00000.video-codec: non legacy binding
[ 6.003894] qcom-venus aa00000.video-codec: Direct firmware load for qcom/sc8280xp/LENOVO/21BX/qcvss8280.mbn failed with error -2
[ 6.003900] qcom-venus aa00000.video-codec: fail to load video firmware
[ 6.008167] qcom-venus aa00000.video-codec: probe with driver qcom-venus failed with error -22
Not sure if adding the firmware is sufficient or if there are other pieces missing. I’ve opened a bug report for the missing fw: Bug #2115199 “Missing qcom venus firmware” : Bugs : linux-firmware package : Ubuntu
Assuming you’re on Plucky, can you give this linux-firmware package a try: arm64 build of linux-firmware 20250317.git1d4c88ee-0ubuntu1.3+20... : linux-firmware : Juerg Haefliger
