AMD Radeon RX 6800, 6800 XT and 6900 XT status?

<< < (3/3)

Hasturtium:
Reporting with an RX 6600 that’s been cheerfully hassle-free since kernel 6.1. So long as you hit that criterion, the 6700 should be a delight.

adaptl:
how did you guys get your 6600 set up? I'm stuck on linux 6.6 and I can only boot to ast, with no graphics acceleration

MPC7500:
From the wiki:

--- Quote ---AMD Radeon RX 6600 (XT) (Navi 23) - "amdgpu" driver works with 6.1.0, 6.2.0, 6.3.0, 6.4.0, 6.5.0, 6.8.0, 6.9.0, 6.10 and 6.11 in both 4k and 64k pagesize in LE; anything older does not work. Not tested with petitboot. Issues noted on a Sapphire Pulse RX 6600 with X server stability and twitchy application behavior; XFX Speedster SWFT 210 RX 6600 has run without incident or issue.

AMD Radeon RX 6700 XT - Works fine with Gentoo (Linux 6.3.3) with 4KiB page size, LE. Not tested with BE or 64KiB. Not tested in Skiroot.

Nevermind, the problem wasn't with my card, my kernel, or my petitboot. I booted up fedora workstation and gfx worked fine. The problem was just with KDE (and other DEs) not accepting multiple graphics drivers as described elsewhere on the wiki.

Before, I wasn't able to log in and set my system up without enabling the ast, so blacklisting it was problematic. But I was talking to some guy on IRC, he reminded me that you can access petitboot over serial. That's good enough for my setup. I can just use the VGA disable jumper and turn the PC on with autoboot most of the time.

The one problem I have right now is that I use genkernel's initramfs to unlock my LUKS storage, so I need to build that with amdgpu or something, otherwise I have to do it over serial. But yeah having serial interface to petitboot is awesome because it gets handed over to the main OS with kexec.

Too much information, I know. but I like to just follow up on this sort of stuff online just in case its useful to someone else. You wouldn't believe how much time ive spent on a wild goose chase flashing firmware. And all this stuff gets fed into a search engine or an LLM anyways...
