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.
