Hi David, Leo,


Thank you for the UMSCH patches.

Are the  UMSCH and  vcn firmware are upstreamed ?
I want to try this on Strix.

not yet - we are working on it for kernel first. A few patches here need to be reviewed/acked, then cherry-picking one patch which is in another branch as dependency. I have firmwares used for testing and branches for mesa and libdrm to support the kernel features, but not ready for upstreaming.
