drm-fbsd12.0-kmod black screen with SUMO (Radeon HD 6530D) on FreeBSD 12.0 and 12.1 #196

Open Zirias opened 4 years ago

Zirias commented 4 years ago

Loading radeonkms.ko disables my screen as it doesn't seem to find any displays. This is my graphics chip, integrated in an early AMD APU:

vgapci0@pci0:0:1:0:     class=0x030000 card=0x96401849 chip=0x964a1002 rev=0x00 hdr=0x00
    vendor     = 'Advanced Micro Devices, Inc. [AMD/ATI]'
    device     = 'Sumo [Radeon HD 6530D]'
    class      = display
    subclass   = VGA

Example of a log of this issue:

On FreeBSD 12.1, this doesn't work any more, so I tried to build the drm-v5.0-fbsd12.1 branch instead, which also succeeds to initialize my display, but crashes when used from X with hardware acceleration enabled. Loading this newer radeonkms.ko gives a log like this:

My assumption is that this was broken in Linux 4.16 and fixed in later versions, but so far, I wasn't successful myself in finding the key difference between the various versions ...

I just tried the drm-fbsd11.2-kmod port (based on 4.11 I think?) by removing the check for ${OPSYS} == FreeBSD && ${OSVERSION} > 1200000 -- it works fine on my FreeBSD 12.1 system and I have accelerated rendering back without any crashes :)
