Reuse framebuffer after a kexec (amdgpu / efifb)

[Guilherme G. Piccoli]

Thanks a lot Alex / Gerd and Thomas, very informative stuff! I'm glad
there are projects to collect/save the data and reuse after a kdump,
this is very useful.

I'll continue my study on the atombios thing of AMD and QXL, maybe at
least we can make it work in qemu, that'd be great (like a small
initdriver to reprogram de paravirtual device on kexec boot).

Cheers,


Guilherme
