Bug ID: 95078
Summary: [Bisected] dGPU broken in linux 4.4.7
Product: DRI
Version: XOrg git
Hardware: Other
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
Assignee: dri-devel@lists.freedesktop.org
Reporter: nille.kungen@gmail.com
Kernel 4.4.7 broke support for my second graphics card and with that DRI 3.
In 4.4.7 it gets wrong ID with listproviders, it worked in 4.4.6.
Bad:
xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x76 cap: 0xf, Source Output, Sink Output, Source Offload, Sink
Offload crtcs: 4 outputs: 3 associated providers: 0 name:ARUBA @
pci:0000:00:01.0
Provider 1: id: 0x3f cap: 0x0 crtcs: 0 outputs: 0 associated providers: 0
name:HAINAN @ pci:0000:01:00.0
Good values are 0x4f and 0x86.
Bisect
git bisect bad | tee -a /root/bisect.log
791b5b0d2d01542a87af4b5f8fb2504ce2d5b352 is the first bad commit
commit 791b5b0d2d01542a87af4b5f8fb2504ce2d5b352

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.

Nice to see that the commit was reverted in 4.6RC5 and i can confirm that 4.6RC
now works.
I hope it also gets reverted in 4.4.y and 4.5.y as well.

Looking at the info i supplied in
http://www.linuxquestions.org/questions/slackware-14/current-14-2-and-dri-3-and-dri_prime-ain't-working-4175578108/
It looks like it's related to 94874 only kernel versions differ.

If the commit is reverted from the 4.4.y and 4.5.y this could be marked as
solved.
