src/sys/arch/x86/x86: genfb_machdep.c
Log Message:
x86/genfb: Re-enable shadowfb by defualt for now.
Something makes radeondrmkmsfb, at at least, extremely slow, and it's
not yet clear what, and shadowfb=true fixes it. I verified that the
framebuffer pages are correctly getting mapped write-combining, so
the page table entries aren't the problem -- not sure what is the
problem.
