bridgman Do you know if the new libdrm that supports SI cards is called "libdrm-amdgpu-pro-radeon1"?

edit: ah sorry you are asking about PX there, maybe depend on combo if it is intel or amd cpu... but AMD is known to not writing documantation So maybe you should use modesetting ddx and not amdgpu when PX setup is there or something.Last edited by dungeon; 08 December 2016, 06:52 PM.

I see a lot of GCN 1.0 parts. Title of the page should be "Linux Download Center" unless something is going wacky in the "route to a different server depending on where you are" site logic.
Failing that, go to amd.com, click on "Get Drivers", then click on any of the first four "Linux" links. If you go down too far you'll end up getting legacy drivers.Test signature

But you're right, my model (R7 M360) is not listed in the release notes at http://support.amd.com/en-us/kb-arti...ase-Notes.aspx .
R7 M350/M380 are now supported although they're only GCN 1.0/1.1 .
Also the complete R7 M400 series is supported which should contain at least some Iceland chips (M440/460?).
What hell of AMD marketing department came up with this highly confusing naming scheme with different GCN generations in the same series?

They just don't write proper docs, what is advertised and what you get in reality greatly differ. Whatever marketing names are used and they write there, people with any of the following GPU names can try it (basically all GCNs)
BONAIRE, CARRIZO, FIJI, HAINAN, HAWAII, KABINI, KAVERI, MULLINS, OLAND, PITCAIRN, POLARIS10, POLARIS11, STONEY, TAHITI, TONGA, TOPAZ and VERDE

Originally posted by twriter View PostCurrently, the open stack offers a better user experience for hybrid graphics because APU and dGPU share the same GL implementation (Mesa).
Originally posted by twriter View PostPX support in the pro stack requires you to logout when switching between power saving and performance modes whereas the open stack supports DRI PRIME GPU offloading so you can use the dGPU only when you need it.
Still usually I get an empty OpenGL application window what has to get minimized/resized once before the content is shown.
Originally posted by twriter View PostRecently, we've pushed a lot of fixes upstream for hybrid graphics.
At the moment I still wonder about PCIe transfer rate to the dGPU. 16x is supported but only 1x is used afais.
Originally posted by twriter View PostAn easy way to get these is to use only the dkms package from the pro stack, with all other graphics components from Ubuntu.
Yes, I saw that 16.50 was trying to install the dkms packages for 4.9rcx on my system but failed.
Originally posted by twriter View PostSome laptops also require an upgraded DDX (xserver-xorg-video-amdgpu, 1.2.0 recommended).
Originally posted by twriter View PostHaving said that, PX systems tend to have a lot of quirks so unless we've tested your specific model, YMMV.
Just wonder why upstream amdgpu works and amdgpu-pro not?
