[SOLVED] Vulkaninfo amdgpu on -current

ernie young · 09-01-2020, 10:13 PM

Hello,

I ran vulkaninfo on both user & root and get the same error:

Code:

vulkaninfo
ERROR: [Loader Message] Code 0 : /usr/lib/libvulkan_radeon.so: wrong ELF class: ELFCLASS32
ERROR: [Loader Message] Code 0 : /usr/lib/libvulkan_intel.so: wrong ELF class: ELFCLASS32
ERROR at /tmp/Vulkan-Tools-sdk-1.2.141.0/vulkaninfo/vulkaninfo.h:240:vkEnumerateInstanceExtensionProperties failed with ERROR_INITIALIZATION_FAILED

I have looked at other information of people going through the same thing but I feel that I am missing something subtle. I tried appending

Quote:

radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1

to my elilo.conf but it disappears after rebooting (I had a generic kernel but it was erased when I ran eliloconfig previously; will work on this after I resolve this issue). I noticed that from /var/log/Xorg.0.log there's no amdgpu.

In addition, I tried setting up /modprod./amdgpu.conf (quote above) &

Code:

echo "blacklist radeon" > /etc/modprobe.d/blacklist.radeon.conf

from these websites respectively:
https://www.linuxquestions.org/quest...pu-4175639096/
https://www.linuxquestions.org/quest...el-4175543839/

Thank you in advance for any help provided.

Curiously, my "vulkaninfo" produces the same two errors, but not the third, followed by the full output, starting with: Vulkan Instance Version 1.2.141.

While I am not well versed in Vulkan, It seems that you are running on the radeon driver.

My /etc/X11/xorg.conf has this right now:

Code:

Section "Device"                                                               
        Identifier      "AMD"                                                  
        Driver          "amdgpu"                                               
        Option          "DRI3" "true"                                          
        Option          "TearFree" "true"                                      
        Option          "scaling mode" "Full aspect"                           
        Option          "DeleteUnusedDP12Displays" "true"                      
EndSection

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

Code:

[ 29872.000] (II) LoadModule: "amdgpu"                                         
[ 29872.000] (II) Loading /usr/lib64/xorg/modules/drivers/amdgpu_drv.so        
[ 29872.001] (II) Module amdgpu: vendor="X.Org Foundation"

Try this:

Code:

glxgears -info | head -n5

What does the output say? You may be using a device not supported by the amdgpu driver.

I personally have nothing appended to my kernel parameters, and it works as it should with a fairly recent card.

EDIT: Oh, also, I see that you are running -current, but to other users with a similar problem: if your AMD graphics card is very recent, Slackware 14.2 does not have the most recent X11/Mesa/DRM software to support it, even if you use the most recent kernel. In that case, you will need to switch to the -current branch.

I think here is your problem, i never had issues with vulkan on my hd7870, appending the parameters that you listed to the boot config was enough, but I'm using normal lilo with the huge kernel.
What is your GPU by the way?

Are you certain your GPU is supported by the amdgpu driver?

ernie young · 09-02-2020, 06:59 PM

Fat_Elvis & giomat, thank you for the help. So I get home from work and I powered up my computer and long an behold, my vulkan is working. Not sure why but my new system has been acting with a lot of glitches since I installed it a few days ago. (I had a partition gone wrong and took the courage to go from 14.2 to -current.)

Code:

$ glxgears -info | head -n5
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
GL_RENDERER   = AMD Radeon HD 7800 Series (PITCAIRN, DRM 3.35.0, 5.4.60, LLVM 10.0.1)
GL_VERSION    = 4.6 (Compatibility Profile) Mesa 20.1.6
GL_VENDOR     = X.Org

It's the same card as yours giomat: HD 7870

Since I don't have it in the bootloader, it got it from /etc/modprod.d/. We'll see how it plays going forward.

walecha · 09-02-2020, 08:35 PM

If this GPU is not the primary GPU or this GPU is the primary GPU but you don't need to see some kernel early printk or you are ok with 1 or 2 seconds of blank screen until the primary GPU framebuffer, then adding these line into /etc/modprobe/gpu.conf is sufficient to use amdgpu driver instead of radeon driver:

Code:

$ echo 'options radeon cik_support=0 si_support=0' | sudo tee -a /etc/modprobe/gpu.conf
$ echo 'options amdgpu cik_support=1 si_support=1 dc=1' | sudo tee -a /etc/modprobe/gpu.conf

When udev is started, the first line will disable support for CIK and SI models in radeon driver and then second line will enable support for CIK and SI models in amdgpu driver and using it to control the GPU.

If this GPU is the primary GPU and you want to see some kernel printk just after bootloader boots the kernel until GPU framebuffer takes over, then you have to include amdgpu driver into your initrd and add this line into your bootloader configuration:

Code:

radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1 amdgpu.dc=1

The full configuration /etc/X11/Xorg.conf is not required anymore in the normal use of recent Xorg (maybe starting from version 1.19) or if you are using wayland because Xorg or wayland will use udev to initialize the required hardware and input/output events. You can add some configuration in /etc/X11/xorg.conf.d/tuning_or_quirk.conf for special tuning or some quirk for buggy hardware like this:

Code:

$ cat /etc/X11/xorg.conf.d/20-intel.conf 
Section "Device"
    BusID      "PCI:0:2:0"
    Identifier "Intel Graphics"
    ## Default using xf86-video-intel
    Driver     "intel"
    Option     "AccelMethod" "sna"
    Option     "TearFree"    "true"
    Option     "SwapbuffersWait"  "true"
    Option     "ZaphodHeads" "VGA1,HDMI1,DP1"
    Option     "Backlight" "intel_backlight"
    ## Use xf86-video-modesetting
    #Driver     "modesetting"
    #Option     "AccelMethod" "glamor"
    ## global options
    Option     "DRI" "3"
EndSection

Is this 64-bit or 32-bit Slackware? Do you have multilib? I believe vulkaninfo uses the icd files in /usr/share/vulkan/icd.d. Here it loads 'radeon_icd.i686.json' first which shows a similar message and then produces the correct output with radeon_icd.x86_64.json. It will have the opposite behavior if I run /usr/bin/32/vulkaninfo instead.

ernie young · 09-03-2020, 06:49 PM

@walecha, yes, the Radeon card is the main one, with also integrated graphics from my Intel processor.I have updated the modprod.d/gpu.conf file. As for the bootloader, that requires a bit more time and understanding on my part. Thank you for your help.

@orbea, good questions, forgot to mention x64 & multilib. Thank you again for your help.

If you see that I am missing gaps, please feel free to point them out.

Yes, most common hardware works just fine without, but Xorg.conf is still very useful for tuning input devices, or driver options like the very useful "TearFree" present on "intel" and "amdgpu" drivers.

Thanks for the tip about the xorg.conf.d folder. I suppose this has the same effect as collating all options in one file.

I can't find the official amdgpu pages right now, as usual with most freedesktop.org projects, but the Gentoo wiki seems to list your PITCAIRN GPU as being supported by the driver. You also have sufficiently recent Mesa and DRM versions.

Glad to hear that.

I have also had some problems (the video getting corrupted, and hanging completely in my case) sporadically since I have installed a new mainboard, and I am convinced this is a hardware/ROM issue. This is usually solved with a hard reboot. It only happens within minutes of a reboot, so it isn't a real problem, but I wonder if it happens to other AMD CPU and/or AMD GPU owners.

ernie young · 10-04-2020, 06:43 PM

I have been playing with the part of walecha

Quote:

you have to include amdgpu driver into your initrd and add this line into your bootloader configuration:
Code:
radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1 amdgpu.dc=1

however I don't know how to do this. For example, on the bootloader I have included it as follows:

Code:

append="radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1 amdgpu.dc=1"
chooser=simple
delay=100
timeout=100
#
image = /boot/vmlinuz-generic-5.4.60  
 initrd = /boot/initrd_5.4.60.gz  
 root = /dev/sda2  
 label = 5.4.60  
 read-only

image=vmlinuz
        label=vmlinuz
        initrd=initrd.gz
        read-only
        append="root=/dev/sda2 vga=normal ro"

Furthermore, how do I update elilo because when I use eliloconfig my generic block gets erased. Should I be using efibootmgr?

Also, how do I include amdgpu on my initrd?

Code:

# initrd created with 'mkinitrd -c -k 5.4.60 -f ext4 -r /dev/sda2 -m xhci-pci:ohci-pci:ehci-pci:xhci-hcd:uh 
ci-hcd:ehci-hcd:hid:usbhid:i2c-hid:hid_generic:hid-asus:hid-cherry:hid-logitech:hid-logitech-dj:hid-logitec 
h-hidpp:hid-lenovo:hid-microsoft:hid_multitouch:jbd2:mbcache:crc32c_intel:crc32c_generic:ext4 -u -o /boot/i 
nitrd.gz'

I have looked into different posts, Slackware guides and websites but I haven't really found these specifications. I am still learning to make the connections. Thank you in advance.

Bonus question

: do I have to recompile VIM to have it copy from VIM to paste outside, like to LQ? :-) Pasting into VIM with Shift+Insert from outside, works.

EFI bootloader like elilo, grub, or refind does not need to be updated/reinit like lilo. Just edit/change the config file and it will using new boot configuration on the next boot.

Just add amdgpu in the modules list eg.

Code:

-m xhci-pci:ohci-pci:other-module:another-module:amdgpu

As far as I know, you can't stack appends with elilo (regular lilo supported a global "append" option and then an "addappend" option that could be in the individual stanzas). I also don't know if elilo supports a global append. You may need to add them for every stanza (which is what I do).

Also, with elilo, you need to have all kernels and initrds residing on the EFI partition (the easiest would be to have them located directly in the EFI/Slackware/ folder, which is where eliloconfig stores them). You would need to copy the 5.4.60 kernel and initrd from /boot to /boot/efi/EFI/Slackware and update the location in the stanza or elilo won't be able to boot them.

I would try an elilo.conf like the following:

Code:

chooser=simple
delay=100
timeout=100
#
image=vmlinuz-generic-5.4.60  
  initrd=initrd_5.4.60.gz  
  root=/dev/sda2  
  label=5.4.60
  append="append="radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1 amdgpu.dc=1 vga=normal"
  read-only

image=vmlinuz
  label=vmlinuz
  initrd=initrd.gz
  read-only
  append="append="radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1 amdgpu.dc=1 root=/dev/sda2 vga=normal"

I'm not a fan of using eliloconfig for anything other than initial set up. It doesn't allow you to keep customizations in your elilo.conf. The nice thing with elilo (and other UEFI bootloaders) is once the efi stub is registered with your motherboard's firmware, you don't need to do anything other than updating the conf file. It doesn't require running anything after updating the conf (unlike lilo, which required you to run lilo to save everything). I just copy my kernel and initrd to the /boot/efi/EFI/Slackware folder and then update the elilo.conf to point to the new files.

ernie young · 10-06-2020, 07:17 PM

Luckily, the huge kernel is working well and can load my OS, but my generic kernel loads an error of ninety nines (99). This is how I tweaked the new elilo.conf:

Code:

chooser=simple
delay=100
timeout=100

# generic kernel
image = /boot/vmlinuz-generic-5.4.60  
 initrd=initrd_5.4.60.gz  
 root=/dev/sda2  
 label=5.4.60  
 read-only
 append="radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1 amdgpu.dc=1 resume=/dev/sdb2"

# huge kernel
image=vmlinuz
        label=vmlinuz
        initrd=initrd.gz
        read-only
        append="root=/dev/sda2 vga=normal ro"

I also commented out the two lines from /etc/modprod.d/gpu.conf unless I need them:

Code:

options radeon cik_support=0 si_support=0
options amdgpu cik_support=1 si_support=1 dc=1

I did add what walecha suggested to the mkinitrd. @Walecha, how did you come across this "other-module:another-module:amdgpu"? I looked for something to reference for the future but could not find this specific line on the net.

@bassmadrigal, I saw this as a typo on your comment, but would like to be sure:

You need to move your generic kernel to /boot/efi/EFI/Slackware and change the elilo.conf to remove the /boot/ from the image line (make sure your initrd is in there as well).
