Hi Michel,

all your patches, both the already merged kernel bits in radeon/amdgpu 
and also all the userspace bits in libdrm/ati-ddx/amdgpu-ddx are all

Reviewed-and-tested-by: Mario Kleiner <mario.kleiner.de at gmail.com>

I successfully tested with old/current userspace and the new userspace 
patches from your own libdrm/ati-ddx/amdgpu-ddx repos, under radeon-kms 
with HD-5770 and amdgpu-kms with R9 380, under DRI2 and DRI3/Present 
with the new userspace and at least DRI3/Present with the old/current 
userspace (can't quite remember if i also tested with DRI2 on 
old/current userspace, but probably). Hardware measured timing tests all 
work fine.

So all is good, except for pre-DCE4 without pflip irqs, but for that see 
the patchset i just sent out, which should make those old asics work 
well as well.
