--- Comment #78 from Alex Deucher alexdeucher@gmail.com --- (In reply to Maxim Sheviakov from comment #77)
How do I do it? For the first link: Is it enough to copy http://cgit.freedesktop.org/~agd5f/linux/tree/drivers/gpu/drm/ radeon?h=new_smc to 4.3 source tree? Or should I use the git ver of kernel?
Either fetch the git tree and build it directly or apply the top 4 patches to another kernel.
Second link: what should I do with it?
Add the files to /lib/firmware/radeon and update your initrd if you are using one.
