amd apu vga card driver for FreeBSD 12.1 tutorial for beginner

I’m a newbie for freebsd and have some experience for linux.
I have just installed FreeBSD for one week, I met a lot of trouble when I use it.
I just want to tell everyone that how to solve this problem then you could save you time .

This article only use for amd ryzen cpu (r3 2300u , r5 3500u, r7 3700u),radeon series , vega series vga card

R5 3500u have been tested


FreeBSD 12.1 can’t detect your vga card with drm driver , because the driver have bug .


I found this driver in FreeBSD github after searching a lot.

https://github.com/FreeBSDDesktop/kms-drm/tree/drm-v5.0-fbsd12.1

download it and unzip it
unzip kms-drm-drm-v5.0-fbsd12.1.zip

you have to install xorg before you do following steps

at first you have to install drm-kmo and gpu-firmware package from ports or pkg , it will install gpu-firmware automaticly

$ sudo pkg install drm-kmod
New packages to be INSTALLED:
drm-kmod: g20181126 [FreeBSD]
drm-current-kmod: 4.16.g20190305 [FreeBSD]
Message from drm-current-kmod-4.16.g20190305:

add a line into /etc/rc.conf.

For amdgpu: kld_list="amdgpu"
For radeonkms: kld_list="/boot/modules/radeonkms.ko"

to install xf86 admgpu driver

$ sudo pkg install xf86-video-amdgpu

restart your computer after above steps .
You will see this kind of infomations:

that means your amdgpu driver is loaded correctly.

add your UID is a member of the "video" group.
$ sudo pw groupmod video -m $USER


Run startx , go to xwindows, if have some problem with going into xwindows ,
you could find some message in /var/log/Xorg.0.log or run startx will got "[KMS] drm report modesetting isn't supported "
it maybe the pcids file is missing your device_id, just put your device_id in it.

You should run pciconf -lv to find vga card
for example:
#pciconf -lv

iwm0@pci0:2:0:0: class=0x028000 card=0x00148086 chip=0x25268086 rev=0x29 hdr=0x00
vendor = 'Intel Corporation'
device = 'Wireless-AC 9260'
class = network
vgapci0@pci0:4:0:0: class=0x030000 card=0x8589103c chip=0x15d81002 rev=0xd2 hdr=0x00
vendor = 'Advanced Micro Devices, Inc. [AMD/ATI]'
device = 'Picasso'
class = display
subclass = VGA
there are deivce id and vendor id in chip field.
0x15d8 is device_id
0x1002 is vendor_id


find your device_id in you /usr/local/share/pciids/pci.ids files
add your device id in AMD group when you can't find it in the file.

And then run startx again , it works fine

if you xorg have VSync problem ,enable TearFree into your xorg.conf


Section "Device"

### [arg]: arg optional
#Option "ShadowFB" # [<bool>]
#Option "DefaultRefresh" # [<bool>]
#Option "ModeSetClearScreen" # [<bool>]
Identifier "Card0"
Driver "amdgpu"
BusID "PCI:4:0:0"

Option "TearFree" "On"

Option "DRI" "True"
Option "AccelMethod" "exa"
Option "MigrationHeuristic" "greedy"
EndSection


for saving power , put this in your loader.conf . the following lines will enable dynamic power management on you gpu
compat.linuxkpi.amdgpu_dpm=1
compat.linuxkpi.amdgpu_bapm=1
compat.linuxkpi.amdgpu_runpm=1
compat.linuxkpi.amdgpu_dc=1


if you got xorg issue with "No Screen found " , maybe you work on securelevel mode , you can look at your /var/log/Xorg.0.log , you will find these information here

[ 18393.601] (WW) checkDevMem: failed to open /dev/mem (Operation not permitted)
[ 18393.601] (II) "glx" will be loaded. This was enabled by default and also specified in the config file.

solution: turn off securelevel and restart



#note:
(1)don’t use any secure level when you use the Xorg because the driver will be not loaded as you open the secure level. it’s so strange but it’s true.
(2)mtrr will be not added correctly when your bios setup the video memory to auto , maybe this is drivers bug,because windows10 have not any problem.
(3) you can use "pkg lock drm-fbsd12.0-kmod" for preventing it from upgrading

cd kms-drm directory and run make and make install, the module will install /boot/module directory

Thank you. The 5.0 driver allows my RX590 to work! I am only having problems now with the fan speed, as it appears the GPU fans are spinning at near full speed, creating too much noise.

A little clean-up for the instructions is needed, as there are some problems with the link. The direct download for the file is:
https://github.com/FreeBSDDesktop/kms-drm/archive/drm-v5.0-fbsd12.1.zip

You will also need to download the firmware and install it.
https://github.com/FreeBSDDesktop/kms-firmware/archive/master.zip

A problem with following the instructions above, about installing drm-kmod from packages is that if you later on simply run pkg upgrade, it will overwright the updated drivers.

The power management options do not Need Linux support,it’s amdgpu drm driver option. You can search them in bing.com.

Thank you. I have found the documentation for the options. Hopefully I will have opportunity to try it out later this week.

You know, this is entertaining, but actually quite wrong. To install drm-v5.0 you need the graphics/drm-devel-kmod port and, of course, you won't be able to build it on 12.1.

Interesting. You still should rather edit the version stuff in the port's makefile instead of all these strange steps.

if you want to resume and suspend works, you should change linuxkpi makefile. but it works fine without suspend and resume when you dont change anything.
the follow post is for suspending and resuming I made it.

You will also need to download the firmware and install it.
https://github.com/FreeBSDDesktop/kms-firmware/archive/master.zip
This confuses me - what firmware? I installed graphics/drm-kmod and x11-drivers/xf86-video-amdgpu and the system works perfectly, 3d graphics included. There is some garbling of the FreeBSD boot logo before the AMD driver kicks in but other than that it works fine.

Running this on an RX570 but that shouldn't matter should it?

As a side note, is there any way to get the GPU temperature?

The firmware is part of graphics/drm-kmod. If you are manually installing the source from github, you will need to also manually install the firmware. There is no need to install the port if you are manually installing, and as I found out, if it is installed beforehand, running a blanket pkg upgrade will overwrite the 5.0 drivers. If installing the port gives you proper graphics support, then you don't need to install the 5.0 drivers. In my case, the 4.16 drivers from ports would not work.

I too am hoping to have some way to monitor the GPU temperature and fan speeds, but that may not be doable right now.

Ah ok, thanks for the clarification. I installed from ports so I should be good to go. Everything works fine: the monitor sleeps and wakes up, 3D works, I can go from fluxbox to terminal with no issues. The only issue is screen jumble after the FreeBSD logo during boot, until the driver kicks in but I can live with that.

that means your amdgpu driver is loaded correctly.

add your UID is a member of the "video" group.
$ sudo pw groupmod video -m $USER


Run startx , go to xwindows, if have some problem with going into xwindows ,
you could find some message in /var/log/Xorg.0.log or run startx will got "[KMS] drm report modesetting isn't supported "
it maybe the pcids file is missing your device_id, just put your device_id in it.

You should run pciconf -lv to find vga card
for example:
#pciconf -lv

iwm0@pci0:2:0:0: class=0x028000 card=0x00148086 chip=0x25268086 rev=0x29 hdr=0x00
vendor = 'Intel Corporation'
device = 'Wireless-AC 9260'
class = network
vgapci0@pci0:4:0:0: class=0x030000 card=0x8589103c chip=0x15d81002 rev=0xd2 hdr=0x00
vendor = 'Advanced Micro Devices, Inc. [AMD/ATI]'
device = 'Picasso'
class = display
subclass = VGA
there are deivce id and vendor id in chip field.
0x15d8 is device_id
0x1002 is vendor_id


find your device_id in you /usr/local/share/pciids/pci.ids files
add your device id in AMD group when you can't find it in the file.

And then run startx again , it works fine

if you xorg have VSync problem ,enable TearFree into your xorg.conf

add solution for Xorg "No Screen Found"
I can confirm that both solutions amdgpu and suspend works for me on the Lenovo E595. Thank you. It seems though that the sound doesn't work. Did you manage to get the sound working with your laptop?
Thank you

Thank you but I wasn't testing your solution :). My system works perfectly just using the standard x11/drm-kmod driver.
So what is the actual status on this to get vega working (all versions?)? Is it suffice to install x11/drm-kmod or x11/drm-kmod-devel and does it have to be from ports, or do packages work as well? I am asking the latter because on a system I have with an old Radeon the installation with packages gives:

Code:
$ pkg info | grep drm
drm-fbsd12.0-kmod-4.16.g20200221 DRM modules for the linuxkpi-based KMS components
drm-kmod-g20190710             Metaport of DRM modules for the linuxkpi-based KMS components
libdrm-2.4.102,1               Userspace interface to kernel Direct Rendering Module services
linux-c7-libdrm-2.4.91         Interface to kernel Direct Rendering Module (Linux CentOS 7.6.1810)
