Hello. I've got a HP Elitebook 850g1 with hybrid graphics:
$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT
Integrated Graphics Controller (rev 0b)
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] Mars [Radeon HD 8730M] (rev ff)
$ sudo cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS-Audio: :Off:0000:03:00.1
2:DIS: :DynOff:0000:03:00.0
I'm running Debian (sid, x86_64) with kernel 4.4.0-trunk-amd64 (same happens
with the 4.3.0-1-amd64 kernel) and Xorg 1:7.7+13 (1.18.0).
I'm having an odd issue where Xorg loads the correct "radeon" driver, but after
a split second, unloads it again and loads "modesetting":
[ 13.688] (II) config/udev: removing GPU device
/sys/devices/pci0000:00/0000:00:1c.4/0000:03:00.0/drm/card1 /dev/dri/card1

[ 13.693] (II) Loading
/usr/lib/xorg/modules/drivers/modesetting_drv.so
Full Xorg log at http://ziff.soleus.nu/Xorg.0.log.txt. I don't have a
xorg.conf, and no snippets in xorg.conf.d either.
This results in two providers in xrandr, Intel and modesetting (as opposed to
radeon, as I had before):
$ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x7d cap: 0xb, Source Output, Sink Output, Sink Offload
crtcs: 4 outputs: 6 associated providers: 0 name:Intel
Provider 1: id: 0x140 cap: 0x3, Source Output, Sink Output crtcs: 2
outputs: 2 associated providers: 0 name:modesetting
I can't set an offload sink:
$ xrandr --setprovideroffloadsink modesetting Intel
X Error of failed request: BadValue (integer parameter out of range
for operation)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 34 (RRSetProviderOffloadSink)
Value in failed request: 0x140
Serial number of failed request: 16
Current serial number in output stream: 17
And, I suppose this is normal because of the above, DRI_PRIME doesn't do much:
$ glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile
$ DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile
Strangely enough, the /sys device link for "card1", as mentioned in the Xorg
log, still points to the "correct" ATI device:
$ ls -l /sys/class/drm/card1/device
lrwxrwxrwx 1 root root 0 Feb 3 21:14 /sys/class/drm/card1/device ->
../../../0000:03:00.0
I'm a bit stumped here. How can I get my radeon device back in the xrandr
providers and working via DRI_PRIME?
Thanks,
Lennert
