The Expected Linux Driver State For The Radeon VII

There was Plasma on the keynote https://youtu.be/bibZyMjY2K4?t=1975 so one would expect Linux support.

That was about threadripper

I thought we knew that Vega20 is not just a die shrink of Vega10, because of things like much greater double precision perf and 8bit support. As it is almost certain that Vega VII is a Vega20 part (MI50 has the exact same configuration except the 32GB HBM2) there must be driver updates.?

Really?


AMD Stages A Number Of Fixes Ahead Of Linux 4.20~5.0 - Plus Vega 20 "MGPU Fan Boost"

a lot of Vega 20 enablement code including compute support, initial xGMI support, VCN dynamic power gating, DC display code enhancements, VCN JPEG engine support,

With this first batch of fixes for this next kernel, there are several display/DC fixes, endian fixes for Vega, Vega 20 PowerPlay fixes, Picasso/Raven/Raven2 PowerPlay fixes too, manual fan control mode switching fixes, and a variety of other fixes pertaining to the yet-to-be-released Vega 20, Raven 2, and Picasso hardware. It looks like by the time that hardware

As it is almost certain that Vega VII is a Vega20 part (MI50 has the exact same configuration except the 32GB HBM2) there must be driver updates. Or is it possible to just use the old driver, and thus just not enabling those new features? Or was Vega10 already shipping those features, just without a driver available?

There were new ID added last month for both Vega 10 and Vega 20. But with regards to 'no changes', I am referring to what is already in the driver.

Phoronix: The Expected Linux Driver State For The Radeon VII

With yesterday's surprise announcement of the Radeon VII "Radeon 7" as a new $699 7nm second-generation Vega consumer graphics card launching in early February, you may be wondering about the open-source Linux driver support state. While nothing official has come down the wire yet, here is what appears to be the state for this new Vega graphics card on Linux...
