You could enable UVD support on amdgpu using the original firmware from radeon, but you'd have to adjust the memory map on the GPU for SI to match radeon.  So updated firmware is not a requirement per se, it's just needed to keep the memory map the same as other GPUs.

Hi Matthew,

Back in November 2017, Piotr Redlewski, provided some patches for UVD support in the SI cards, the thread had the same subject as this message.

The outcome of a conversation between himself and other developers on the list was to wait for something in updated firmware.  As this was over 2 years ago, I was wondering if the firmware has been updated sufficiently for Piotr's patches to be reconsidered or modified to deliver the UVD support for the SI cards?

we discussed that internally quite lengthy and the firmware will probably never be released.

To be honest we actually considering dropping SI support completely from amdgpu.


Thanks for you help

Kind Regards
