I presume you are referring to fw_update(1)?
Which version of OpenBSD are you using? You might need -current for that card, although it should be supported by the amdgpu firmware tarball for the 6.8 -release & -stable versions (which is dated 2020-06-19 and contains Polaris files). I suppose you could boot from the ramdisk kernel then delete the files under /etc/firmware/amdgpu/ and make the directory immutable so that fw_update(1) will fail but that seems hacky in the extreme and will leave you without a functional GPU. Note that the nomodeset kernel parameter would also prevent the GPU from working under GNU/Linux because AMD cards require kernel mode setting so it isn't really a solution under that operating system.

not fw_update, but the initial boot after slicing up the drive and installing system components. that boot works fine and installs amdgpu automatically and directs users to install security updates. but then the next boot amdgpu is loaded after the kernel loads all drivers and instead of the screen adjusting to a higher resolution it goes blank/black with a tinge of backlighting. this happens with many distros and by adding nomodeset to grub it resolves the issue and amdgpu may be run without issue. openbsd does not utilize grub so i'm at a loss. |

Try -current then.
No, it doesn't. The amdgpu driver requires kernel mode setting. If you can get to a graphical desktop after applying that parameter then it's probably using the VESA driver, which will give terrible performance.

with openbsd installed i'm not that demanding on gpu performance.. i'd much rather have a stable and secure workable system.
upgraded to current with no change tried some bios settings too to no avail. was running fine early in the year i wonder if i roll back the version it may help. meantime if anyone has suggestions..... i have tried all displyport/hdmi/dvi ports on the gpu. |
