Hello people,
So here's a question. I'm trying to run FreeBSD 12.0 on a new AMD
desktop PC, and it's not working. I've read the relevant parts of the
handbook and release notes, installed the package drm-kmod-g20190710,
and added
kld_list="/boot/modules/amdgpu.ko"
to rc.conf. Booting ends up in a silent hang: screen goes dark,
keyboard and mouse get no response, the system doesn't answer pings.
The only way out is to pull the plug.
Without loading that module, booting succeeds, but /dev/dri doesn't
exist and the X server refuses to run.
I've read the wiki page on graphics, and saw the statement that the
AMD drivers conflict with the EFI frame buffer. That doesn't apply; I
boot FreeBSD the "legacy" way, not through UEFI.
Have I missed something?
The computer is an HP Pavilion Desktop 590-p0025, with an AMD Ryzen 3
2200G processor and Radeon Vega 8 Graphics. The boot messages say
it's
CPU: AMD Ryzen 3 2200G with Radeon Vega Graphics (3493.52-MHz K8-class CPU)
Origin="AuthenticAMD" Id=0x810f10 Family=0x17 Model=0x11 Stepping=0
plus a long list of features.
In /boot/modules, I see files whose names include amdgpu_vega10,
vega12, vega20, and vegam, but not vega8. Could that be the problem?
How do I debug this? Preferably without pulling the plug over and
over.
