Does anyone else have a similar problem?

Nille_kungen 04-22-2016 12:18 PM
I started recompiling the things related to the error but it didn't solve it.
Started to compile different version and found out that the problem is the current kernel.
I tried an older kernel i had installed and it started to work again and that kernel also shows the right ID with "xrandr --listproviders"

Nille_kungen 04-22-2016 01:59 PM
Kernel 4.4.6 work but not 4.4.7 or 4.4.8
I will see if i get time to bisect which commit that caused this so i can report a bug upstreams.

ReaperX7 04-22-2016 02:25 PM
Try adding:

Code:
export DRI_PRIME=1
to your system or user environment variables. Use root to create a file in /etc/profile.d as xorg_prime.sh and entire the command posted above, and then reboot. This should enable your secondary card correctly when you load Xorg.

You should also edit your /etc/X11/xorg.conf or /etc/X11/xorg.conf.d specific vendor file in use the following for your Radeon to use:

Code:
Option "AccelMethod" "glamor"
Option "DRI" "3"
You may need to enable glamor acceleration.

Nille_kungen 04-22-2016 02:35 PM
Glamor is worse for me and i do already have an /etc/X11/xorg.conf.d/20-radeon.conf i don't have problems with how to set DRI 3 it's that last kernel update broke it.
I need to bisect the kernel to see what broke it, 4.4.6 good and 4.4.7 bad.

ReaperX7 04-22-2016 02:41 PM
Have you tried kernel 4.4.8 yet?

Nille_kungen 04-22-2016 02:45 PM
Yes 4.4.8 is bad

ReaperX7 04-22-2016 02:48 PM
What about 4.5.2 or 4.6rc4?

Nille_kungen 04-22-2016 03:11 PM
Those won't be in slackware 14.2 so i haven't checked them i only looking into 4.4
I started bisect now if it goes fast i might finish it tonight and find the bad commit.

Nille_kungen 04-22-2016 03:18 PM
Since it calculates the ID:s wrong it i think it's only an typo and i might even supply a patch upstream but i need to wait for the bisect to finish first to know whats happening.
Normally i wouldn't post about this here but since we're so close to an release i posted so we don't get stable with an broken kernel for some users.

ReaperX7 04-23-2016 07:12 PM
What version of xorg-server is -Current using? 1.18.2 or 1.18.3?

willysr 04-23-2016 09:28 PM
1.18.3

voyagerok 04-24-2016 07:09 AM
Have the same issue on arch linux and fedora. On fedora it started after upgrading kernel from 4.4.6 to 4.4.7, on arch after 4.4.5 - 4.5.1.

It were broken in 4.6RC but it got fixed in 4.6RC5 "Revert drm/radeon: disable runtime pm on PX laptops without
dGPU power control".
But i got good news i did trace it and found the bad commit.
https://github.com/torvalds/linux/co...b2504ce2d5b352
An quick fix is to revert the bad commit.
Patch made with "git show -R 791b5b0d2d01542a87af4b5f8fb2504ce2d5b352 > /tmp/dGPU.patch"
Code:
commit 791b5b0d2d01542a87af4b5f8fb2504ce2d5b352
Author: Alex Deucher <alexander.deucher@amd.com>
Date:  Wed Mar 2 11:47:29 2016 -0500

    drm/radeon: disable runtime pm on PX laptops without dGPU power control
   
    commit e64c952efb8e0c15ae82cec8e455ab4910690ef1 upstream.
   
    Some PX laptops don't provide an ACPI method to control dGPU power.  On
    those systems, the driver is responsible for handling the dGPU power
    state.  Disable runtime PM on them until support for this is implemented.

I wonder if this may effect single cards as well?

Glad you found the fix for it. What is your Xorg.0.log producing now with the patch in place?
