AMD's Radeon RX Announcement For E3 2016

[blubbaer]

A colleague of mine recently showed me some nice work done with Assembler for GCN. This only works with OpenCL with AMDGPU-PRO and RadeonSI. Those drivers don't support this feature officially. So I want to know if there are plans on supporting third party compiler and assembler for developing and optimizing OpenCL programs and OpenGL/Vulkan shaders. I know there is SPIR-V but this a portable IR not a native binary format.

Maybe the benefit of writings shaders and programs in assembler are small but it would be still a nice feature to have. Also to support an official binary format for GCN-native programs should be relatively easy.

Radeon RX, your prescription for awesome.

I'm wondering if FGLRX 15.12 released in 2015 will support the Polaris family in order to run OpenCL programs such as oclHashcat or ethminer that require it or will AMDGPU-PRO be backwards compatible?

No, fglrx isn't being updated for Polaris.

Anybody working on OpenCL for amdgpu?

I saw this on reddit 3 weeks ago.

Also, how about crossfire support on Linux? How about crossfire between a dGPU and an IGP? Will that happen on Linux, and if so, for what chip combinations?

I don't think you will hear much about this. Vulkan supports explicit multiadapter.

In general anything that runs on fglrx with current GCN hardware should run on amdgpu pro + Polaris as well... if it doesn't we would like to hear about it.

Michael, I'm sure you'll ask about open source Vulkan support, but assuming you get can't get any details on that please ask if they'll officially support running the proprietary Vulkan driver with the OSS GL driver anytime soon.

For now I'm more focused on free driver (without blob/proprietary firmware), with OpenGL 4.5 support, vulkan and OpenCL.

Yep. I'd like to know if there is a time frame for open sourcing their Vulkan driver.

I'm divided on whether to remain AMD or go Nvidia for my next gaming PC. Drivers could be the one thing that swings my decision.

phoronix Michael could you ask if it will be possible at some point to switch between radeonsi and amdgpu-pro without rebooting?

rebooting is only required for kernel driver change, mesa should work with amdgpu-pro kernel driver already. libraries should be switchable at runtime with alternatives or something like that.

Or better yet to use one or the other on a per application basis?

i guess it is doable with LD_LIBRARY_PATH tricks
