is 4k desktop possible on freebsd-12?

[tech-lists]

Hi,

I'm trying to get xorg to display 4k. The context is:

FreeBSD 12.0-ALPHA8 r339084 amd64
ports r481640
AMD RX580 GPU
Asus X99 Extreme3 mobo
cpu: intel e5-2699v4
48GB RAM
Samsung UE48JU6410U monitor connected via HDMI

drm-next-kmod-4.11.g20180822

xf86-video-scfb-0.0.4_7
xf86-video-vesa-2.4.0_2
linux_base-c7-7.4.1708_6 and all its xorg/mesa libs

/var/log/Xorg.0.log has this:

so would this indicate the card is 4k capable but the HDMI port on the
card is not? Or the port on the monitor? Or something else?

thanks,

for 4K@60FPS you need DP connection.

Hi

What is the actual problem? Do you get any 4K modes listed when you run
'xrandr' ?
I've been running 4K@60FPS on an external display for a long time on my
Intel laptops. However, that requires DP output. Your HDMI output is most
likely limited to 30 FPS (but should still display 4K resolution...).

thanks,

The problem is, I'd like 4k output but it seems I'm not getting it even
though the card and monitor are both capable of it. Problem also is my
lack of expertise in this area.

xrandr output:

Would that work at 30 fps given that Xorg.0.log shows the following:

[ 3474.097] (II) AMDGPU(0): Printing DDC gathered Modelines:
[ 3474.098] (II) AMDGPU(0): Modeline "3840x2160"x0.0 297.00 3840 4016
4104 4400 2160 2168 2178 2250 +hsync +vsync (67.5 kHz eP)

[ 3474.211] (II) AMDGPU(0): Printing DDC gathered Modelines:
[ 3474.211] (II) AMDGPU(0): Modeline "3840x2160"x0.0 297.00 3840 4016
4104 4400 2160 2168 2178 2250 +hsync +vsync (67.5 kHz eP)

ie, 4k @67.5kHz card output if I'm understanding correctly.

problem is monitor only has HDMI. I'm not sure it'll 4k@30fps is an
acceptable mode for it; need to check

Hi,
The HDMI 2.1 specification (need cables and ports at that level).  It goes to 10K (really) at 120 HZ.    I believe 1.4 supports 60 HZ but FPS tends to be limited to 30 at 4K resolution.  (this is limit of my understanding at this point)

You need check HDMI 2.0 available on video card and monitor.
For HDMI 1.4 you need check of support both card and monitor support 4K@24.

And you need a high quality HDMI 2.0 cable which is not too long.
All too often, people can't get 4K on HDMI because of bad cables.

Yes, the card, cable and monitor are all capable of 4k@30fps. The cable
and monitor were tested by connecting a laptop running linux mint. This
gave a 4k display @ 30fps. So for some reason, the card (AMD RX580)
isn't sending 4k.

Is there a resource explaining how/can anyone tell me how to make the
card send 4k? The xorg section of the handbook unfortunately hasn't been
much help.

thanks,

Do you have anything configured in /etc/X11/xorg.conf? If so, remove the
file and let X auto configure.
Otherwise try switching DDX driver, modesetting or amdgpu

/etc/X11/xorg.conf:

Section "Device"
Driver "amdgpu"
EndSection

VS

Section "Device"
Driver "modesetting"
EndSection

no. But there's a section in the handbook I missed; am reading it now

Hi, just to follow up to this,

I'd run out of time to work on this so installed latest ubuntu desktop,
then ran xrandr and it showed 4k as the top resolution. I didn't have to
make any modifications:

[snip]

DisplayPort-2 disconnected (normal left inverted right x axis y axis)

HDMI-A-0 connected primary 1920x1080+0+0 (normal left inverted right x

axis y axis) 1872mm x 1053mm

3840x2160 30.00 + 25.00 24.00 29.97 23.98
4096x2160 30.00 25.00 24.00 29.97 23.98
[/snip]

and then, additionally, installed boinc-client-opencl and boinc was able
to see the GPUand use it for crunching.

On FreeBSD I couldn't see a way of making the boinc client OpenCL-aware.

On the plus side, FreeBSD was much more stable on this hardware than
Ubuntu. Had to disable hyperthreading in the BIOS to stop it crashing
every few hrs on Ubuntu.

It would be interesting to know, if possible, what Ubuntu is doing that
FreeBSD isn't on this hardware.

thanks to all who replied/tried to help,

[Scott Bennett]

Have you installed lang/clover? If not, then that may be why you don't
see any devices there. For Nvidia, it would be lang/beignet instead.

beignet is for Intel.

If nvidia provides OpenCL for FreeBSD at all, it would be in
nvidia-driver.

(OP has an AMD Radeon RX 580, so clover indeed is the right one. Keep
in mind that clover is… not great, but boinc might work)

Also, boinc on FreeBSD apparently has some compatibility with
Linux-only compute jobs or something — OpenCL will only work with
FreeBSD-native ones.

[Scott Bennett]

Oops. Thanks for the correction! I hadn't looked at it in a long time
and apparently misremembered what the lang/beignet/pkg-descr said.
