Radeon ROCm 4.1 Released - Still Without RDNA GPU Support

It is amazing that many years after the release of RDNA 1, AMD still doesn't have ROCm support for it, yet AMD wants to sell a overclocked 192bit RDNA2 chip without compute at Nvidia ampere 256bit GA104 prices by intentionally busting its 8Gb VRAM buffer because it is "designed for gaming at max 1440P settings". What a joke. Milan, as reviewed by anandtech, is also partly a regression in idle power due to subpar IO Hub chip L3 cache design. What a disappointment.
RDNA is for people whom has empty energy drink cans on their desk and the main color lights flashing all over the place.
GCN is for super computers and servers.Last edited by raun0; 24 March 2021, 04:25 AM.

I thought it was RDNA for desktops, CDNA for HPC?

Good point - I don't think that all the fixes from 20.45 have worked their way into the ROCm release stream yet but we should definitely mention that once the functionality is there.
It's possible that we may have to work through at least conceptually separating "the upstream for our compute components" from "our datacenter releases" as a pre-requisite since right now the ROCm releases kinda serve as both. That is going to be an increasing problem as we expand support to consumer hardware.
Thanks !
is there an effort to simplify/streamline the adoption of ROCm for end users?
Conceptually ROCm/HIP is fascinating and very promising, but it does not compare with the simplicity of installation (and 3rd party support/implementation) of nvidia.
Years ago I used to do cuda on nvidia,
Now I am on polaris (arch linux), i just spent 4 days (probably more, between AMD website, git repos, Arch AUR) to try to get pytorch, torchvisiom, torchtext to run.
Tried from native rocm on arch, to dockers. An ugly mess!
Finally yesterday night by creating my own pkgbuild (and a lot of kicking and screaming) got all instaleld
... to find out that the gpu computing stalls, no errrors, no dmesg -- just trying a jupyter notebook tutorial from torchtext
How do I debug?
How do i ask for help? ( I assume first thing will be: arch is not supported, followed by oh, polaris is not officially supported)
On top of that ROCm 4.1 is out and I have to recompile EVERITHING ....
Come on. ...

Pretty much all their APUs are GCN and I wouldn't claim those are for super computers and servers.

You shouldn't need to do more than "sudo pacman -S rocm-dev rocm-utils rocm-libs" if bridgman is correct about how it should just work w/o the dkms package with newer kernels.
I have a Polaris but no clue on how to run any ROCm stuff cause I've never done that so I can't help much more than that without being point towards some things to try with a tutorial.

It is fairly old, as the packages are old.
After the experience of the latest 4++ days I am tempted to put together my on pkg
With regards with pacman command: AMD expressly states to remove old packages before installing ... (on ubuntu/centos/redhat)

But in their instructions are the remove commands between updates and the notice to compile in a clean chroot when applicable.
