Hello

Sorry for the late reply. It landed in spam for some reason. I apologize.

I have done that but they did not get copied to the /libdata
directory. I do not know when the makefile in the
src/sys/dev/microcode/radeon directory is being invoked.

Yes I manually copied these files and it worked.

On examining the radeok_cik.c file in the cik_init_microcode()
function (or something like that) it looks for the KAVERI*, then the
kaveri* files. As far as I can tell the kaveri* files are the new
firmware. You have to have all the kaveri* files in the libdata
directory, so that it will use all the new firmware, otherwise it
complains that old and new firmware is being mixed.

Thanks for the response.
