AMDGPU-PRO 16.60 Released

[matszpk]

Quick question - does the same program work OK on the Bonaire ? I think that is what you are saying, just wanted to make sure.

Thanks...

Sorry, for my late answer.
Seemingly, Bonaire works fine with that drivers (OpenCL works fine). Unfortunatelly, I didn't make tests on OpenGL and desktop environment (X'es) (only OpenCL). Just, maybe only support for old GCN 1.0 devices have some bug.

bridgman dungeon , just for your record. Installed a fresh copy of Ubuntu 16.04.1, made all upgrades, and installed amdgpu-pro 16.60. Installation went fine, with no errors, but after rebooting the system I was only able to reach the login screen and type the user password, which results in a hard freeze and consequent hard shutdown. Then I was forced to login through the older non-updated kernel and run the uninstall script to sweep out the driver and get a working system again. Just to recall, my system is an HP Zbook 14 G2 mobile workstation, i7-5500u+AMD FirePro m4150 (aka Radeon R7 m260x). So the answer is no, the driver does not work yet with the R7 m260x. To be honest, AMD's official driver page makes a clear distinction between drivers for the R7 m260x (fglrx only) and the R7 m260/m265 (amdgpu-pro or fglrx depending on the OS) http://support.amd.com/en-us/download/linux. Out of curiosity, how is amdgpu-pro supposed to work on hybrid intel-amd graphics systems? Is igpu/dgpu switching supported at all? Finally, I tried also the mesa/radeon stack (current mesa version for non-HWE 16.04 is 12.0.6) and, as I expected, the PRIME offloading stuff is still a complete mess...

Can someone can this to bridgman? I don't really know where to post driver bugs. The new driver does not accept output blocks anymore. Eg, in GLSL:
out block{ vec4 a; vec2 b; } Out; Said shader is compiled to SPIRV for vulkan and causes pipeline creation to crash. I noticed this behavior in the 16.40 driver but I never got around to figuring out why. This is in a vertex shader where any writes to block.a or block.b will cause the pipeline creation to crash inside the driver binary. The problem is still found in the 16.60 driver running on Ubuntu 16.04 LTS.

Just so I get this right, can you walk me through what you are doing ? Shader program written in GLSL, then you are using glslangValidator to convert to SPIR-V and executing with a private Vulkan app ? Can you make any of this available to our devs, eg the shader program ?

You said you noticed the problem appear in 16.40 ? What was the latest version where it worked correctly ? (presumably 16.30 but just checking)

Thanks,
John

bridgman. That's about right. The shader is pretty much the one used in imgui. If you need me to I can strip down my app to just the pipeline creation probably by the next weekend.

The imgui shader is above. I'll put up my stripped down project on github by the next weekend if you still need it.

Can PowerXpress/Enduro machines with Intel GPU run AMDGPU-PRO?

Yup, just use "modesetting-amdgpu-pro" ddx provided instead of "amdgpu-pro" ddx.

On Ubuntu if you have px system just use "amdgpu-pro-install" script, but with "--px" switch:

Usage: $PROG [options...]

Options:
-h|--help display this help message
--px PX platform support
--compute OpenCL support only

That would be setup everything i think... you also have as script in a package called "amdgpu-pro-px" which do:

Usage: $PROG --mode|--reset|--help
--mode powersaving|performance
powersaving: shutdown dGPU, only use iGPU
performance: use dGPU for rendering, iGPU and dGPU for display
--reset
reset the script changes
--ispx
echo "true" if the platform can enable PX, otherwise echo "false"

Where can I find this script? I installed amdgpu-pro with the --px option and after restart the system works with the intel iGPU, but I cannot find how/where to execute this amdgpu-pro-px script (the only executable recognized by default in a terminal is amdgpu-pro-uninstall).

Thanks

Previously with FGLRX you do:

amdconfig --pxl
sudo amdconfig --px-dgpu
sudo amdconfig --px-igpu

(or that amdconfig might be aticonfig whatever)

and now with AMDGPU-PRO it is:

amdgpu-pro-px --ispx
sudo amdgpu-pro-px --mode performance
sudo amdgpu-pro-px --mode powersaving

If not in path then either add a path (export PATH="/opt/amdgpu-pro/bin:$PATH") or do it directly as this should be in /opt/amdgpu-pro/bin/amdgpu-pro-px then check if you can enable it:

/opt/amdgpu-pro/bin/amdgpu-pro-px --ispx

If "true" then do:

sudo /opt/amdgpu-pro/bin/amdgpu-pro-px --mode performance

Log out, log in... and that should be it i guess.

dungeon found it, thanks.
