Hi!

I have FreeBSD 12.0-RELEASE (amd64) installed on iMac 11,1 (late 2009), graphics card is vendor='Advanced Micro Devices, Inc. [AMD/ATI]'
device='RV770/M98L [Mobility Radeon HD 4850]'
I have installed Xorg and when I start it (I use startx from console) is just black screen. The same is when computer start and I have in/etc/rc.conf kld_list="/boot/modules/radeonkms.ko".

In the Xorg.log I have:
[ 505.376] failed to add FB for modeset
[ 505.376] (WW) RADEON(0): Failed to set mode on CRTC 0
[ 505.377] (EE) RADEON(0): Failed to enable any CRTC
I have installed drm-legacy-kmod and xf86-video-ati-legacy.

On the FreeBSD 11.2 I didn't have problem when I load driver from kernel but I had a problem with drm-legacy0kmod - black screen.
Now I am using scfb driver and it works.
And about boot:

sysctl machdep boothmetod shows UEFI

and
sysctl kern.vty shows vt

Thank you.

I installed FreeBSD 12.0 and after kldload radeonkms, saw a deprecation message:

info: [drm] Initialized drm 1.1.0 20060810
drmn0: =======================================================
drmn0: This code is obsolete abandonware. Install the graphics/drm-legacy-kmod pkg
drmn0: =======================================================

drmn0: Deprecated code (to be removed in FreeBSD 13): drm2 drivers

[...]

I installed this package as directed and followed its directions:

Simply add kld_list="/boot/modules/[driver].ko to /etc/rc.conf, for example
[...] kld_list="/boot/modules/radeonkms.ko" for the ATI/AMD GPU driver.

After doing so, I still get the deprecation message seen above. Turns out, it was using radeonkms.ko from this path but the drm2.ko dependency was loaded from the built-in /boot/kernel/drm2.ko. To get rid of the deprecation warning entirely, you must load both drm2 and the GPU driver from /boot/modules, e.g.:

kld_list="/boot/modules/drm2.ko /boot/modules/radeonkms.ko"

I don't know if the GPU drivers can be built to load DRM from the modules directory rather than /boot/kernel, but if not, the documentation needs updating.

the legacy (i.e., drm1) drivers as a port

– appears in the title bar. Seems inconsistent with https://github.com/FreeBSDDesktop/drm-legacy#readme

… drm and drm2 …

13.0-CURRENT as of June 6.
Can't really see the backtrace because of tiny screen, but it seems to be iicbb related at i915_attach.
