To clarify, there are a range of different issues with different amdgpu cards If anybody can provide tips for troubleshooting in any of these bug reports it would be very welcome. https://gitlab.freedesktop.org/drm/amd/-/issues/1519 navi2 - RX 6900 XT https://gitlab.freedesktop.org/drm/amd/-/issues/1446 vega RX 56 Red Dragon https://gitlab.freedesktop.org/drm/amd/-/issues/1293 Fiji-based cards since kernel 5.7 >>> Ultimately, even if it isn't hard to bisect, it doesn't feel fair that >>> AMD is validating their drivers work on x86 before a release but the >>> ppc64le users have to check things after a buggy release. >> >> Unfortunately smaller platforms will almost always get less testing than the >> more popular platforms, and I don't see that trend changing in the >> foreseeable future.

Does anybody know about programs from AMD or any other vendor to make their hardware available to volunteers in the Fedora development world? This is even more critical now that GPU delivery is such a huge problem. Shops that receive stock are selling it at double the RRP. Volunteers won't rush to buy those cards and it will take even longer to fully support them. Simply having a critical mass of developers with the right hardware can make a huge difference. For example, with 7 developers, maybe a given platform is always overloaded but with 8 developers maybe the backlog of bugs is fixed faster than new bugs are discovered. The same phenomena appears in so many domains: what some of us perceive now is like the congestion on a freeway at peak hour when the cars come in faster than they can go out. >> I will also say that regardless of ISA there are going to be times where >> bisection is needed.

Maybe it will be possible in 2022 or beyond. From a Fedora perspective, it could be interesting to align it with the release schedule. https://www.sipforum.org/news-events/test-event-wg-overview-and-charter-sipit/upcoming-sipit-events/ > > Dan > >> >>> How can we encourage greater use of ppc64le and aarch64 in those >>> communities?
