[Solved]Control of automatic GPU switching in Linux 3.13

I'm using the Linux Kernel 3.13 of the testing repository, I have a laptop with Hybrid Graphics ATI/Intel:

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6730M/6770M/7690M XT] (rev ff)

I use the vgaswitcheroo method to shutdown the discrete GPU, it generally show this:

0:IGD:+:Pwr:0000:00:02.0
1:DIS: :Off:0000:01:00.0

But with the New Kernel Feature Automatic GPU Switching I can't shutdown the Discrete GPU of my Hybrid Graphics System, I got this output:

0:IGD:+:Pwr:0000:00:02.0
1:DIS: :DynPwr:0000:01:00.0

I have searched for the power_dpm_state in /sys/class/drm for change to "battery" mode but it file doesn't exist (With the Kernel 3.12 I can set up DPM to "battery" mode)
I don't want to use the Discrete GPU on Linux to save energy and with the DynPwr I got about 60 ͦ C

How Can I set up my Hybrid Graphics Cards for reduce the temperature?

Thanks!

Re: [Solved]Control of automatic GPU switching in Linux 3.13

Thanks for Response! Sorry I forgot to specify how I shutdown my Discrete GPU, I use 

echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

and I got this output:

[root@HP-pavilion-dv6 josejacomeb]# cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :DynPwr:0000:01:00.0

0:IGD:+:Pwr:0000:00:02.0
1:DIS: :DynPwr:0000:01:00.0

I searched in Internet about Hybrid Graphics and Linux 3.13 but I can't find information about this, Where Can I Find Information about Automatic GPU Switching?

Re: [Solved]Control of automatic GPU switching in Linux 3.13

I think this implies that you have reason to assume it's already off. As a last resort you could unbind the radeon DRM driver from the discrete Ati card. But that would be rather crude.

Have you tried passing radeon.dpm=1 to the [core] kernels? It is enabled by default in 3.13, but the infrastructure is only put in place is 3.11/3.12.

Claire is fine.

Re: [Solved]Control of automatic GPU switching in Linux 3.13

Thank you for your responses @Rexilion and @clfarron4 with the last kernel and the recent Linux Firmware my system works very good!

Re: [Solved]Control of automatic GPU switching in Linux 3.13

I am an Arch user on a notebook Asus X53BR-SX026D. This notebook does have powerxpress ATI/ATI switchable graphics, but this feature works correctly only on Windows.
In Arch, either switching or disabling through vgaswitcheroo destabilized my system, X could not (re)start at all, and to reboot I was forced to use SysRq keys.
Since linux kernel 3.11 my notebook finally stopped heating up to 80C right after boot, thanks to dpm.
Runtime power management ( DynPwr and such ) is a great feature for linux, but it works like a disaster for me, because it clearly tries to powerdown the discrete card, and this action leads to above effects.
And here is the cure:
Just add radeon.runpm=0 to kernel command line in GRUB
OR add a config to /etc/modprobe.d/, like that

cat /etc/modprobe.d/boot_radeon.conf
options radeon dpm=1
options radeon audio=1
options radeon runpm=0

But you need to include it into initramfs to truly take effect ( seems to be because of KMS ). To do so, add "/etc/modprobe.d/<config>.conf" to FILES section of /etc/mkinitcpio.conf and rebuild initramfs:

mkinitcpio -p linux

Thank you denspirit for now I'm using the Linux Kernel lts, my hardware doesn't work fine with radeon.runpm=0, I will wait for new versions of the Kernel

Re: [Solved]Control of automatic GPU switching in Linux 3.13

I have a Lenovo S540 with Intel/ATI hybrid graphics and I have been unable to get a graphical boot successfully so far. This thread may well offer me some clues to help but I wonder if any of you can tell me if you had to do anything special on the kernel boot line to get a graphical login at all?

Re: [Solved]Control of automatic GPU switching in Linux 3.13

mcloaked, does X fail because of "No screens found errors"?
Do you have xorg-xf86-video both -ati and -intel installed?

I do have both installed but I have now been able to get the system working fine with graphical boot by adding i915 and radeon to the MODULES line in mkinitcpio.conf and regenerating the initial ramdisk with mkinitcpio -p linux - after that rebooting brought up a normal graphical kdm login greeter screen.

I am using the stock kernel and I have no vgaswitcheroo parameter visible in the /sys area. So exploring using discrete/switcheable graphics is another venture that will need more exploring.

Re: [Solved]Control of automatic GPU switching in Linux 3.13

mcloaked, that's good, you enabled KMS by adding these.
vgaswitcheroo is actually in /sys/kernel/debug, recheck, please, if not searched there. this folder is accessible only by root.
Maybe DRI_PRIME would work for you. please log in to graphical desktop and type:

xrandr --listproviders

Consult with Hybrid Graphics page on ArchWiki, it is very helpful for us notebook owners.

EDIT:
vgaswitcheroo shows up only if KMS is enabled, check it out again if you haven't ^_^

OK I didn't check for vgaswitcheroo after I made the changes but I will do so and report back along with the xrandr command output.  I had been reading that there are some issues with the hybrid graphics code for Intel/ATI in the currently released kernel with a lot of patches coming in 3.14 to fix issues. But I'll report back later by editing this post.

Edit:

There is no vgaswitcheroo directory seen in the running machine - command as root:

# ls /sys/kernel/debug/
acpi        dma_buf        frontswap         kprobes  pkg_temp_thermal  sleep_time     wakeup_sources
bdi         dri            gpio              mce      pstate_snb        suspend_stats  x86
bluetooth   dynamic_debug  ieee80211         mei      regmap            tracing
cleancache  extfrag        intel_powerclamp  mmc0     sched_features    usb
#

also only the Intel graphics chip is seen with xrandr:

$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x48 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 5 associated providers: 0 name:Intel

on the other hand the two cards are seen with lspci:

# lspci |egrep 'VGA|Display'
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
06:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A]

One example of others seeing the vgaswitcheroo disappearing is at http://www.phoronix.com/forums/showthre … sappearing

Re: [Solved]Control of automatic GPU switching in Linux 3.13

I now have the 3.13.7 kernel which won't start the graphical boot (blank screen with a single static cursor at top left), even though it will boot to the console - but kernel 3.13.6 boots normally to the kdm greeter screen.  I have i915 and radeon in the modules section of mkinitcpio.conf file which was the only method I found to get 3.13.6 to boot to a graphical screen.  So I have had to downgrade the kernel to 3.13.6 to keep working on my machine.

My graphics hardware is:

$ lspci | egrep '(Graphics|Display)'
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
06:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A]

but

$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x48 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 5 associated providers: 0 name:Intel

Can anyone suggest a workaround that might get a successful graphical boot in kernel 3.13.7? I did see that there was a reasonable number of radeon related patches in 3.13.7

Re: [Solved]Control of automatic GPU switching in Linux 3.13

You seem to not being the only one with this problem ( see https://bbs.archlinux.org/viewtopic.php?pid=1390393) , but I am sorry I hadn't experienced vgaswitcheroo disappearing while KMS is enabled. Maybe you should check dmesg ( at boot, maybe you will find something interesting, or simply piping it's output to grep "radeon", MAYBE you should pay special attention to microcode related errors ), or Xorg bootup logs ( you said you can login to console) . It's also strange you have only one provider in xrandr output. Is it possible to disable either of videocards in BIOS on your machine?

However I don't know how to interpret the lines above!

Re: [Solved]Control of automatic GPU switching in Linux 3.13

Any line with something like 

ACPI Error: Method parse/execution failed [\_TZ_.TZ01._TMP]

clearly seems to be DSDT bug - a bug in your notebook's low-level firmware. It's nearly insolvable.
You may  try to update BIOS, or decompose@recompile DSDT by yourself.
I have not succeeded in the latter task, though in my case it just can't remember brightness between reboots and lockups GPU if I dare to switch it.

By the way, have you seen the Lenovo S540 wiki page on ArchWiki? It suggests to disable modesetting in intel videocard ( kernel parameter intel.modeset=0 means exactly that).

And I can't say anything about stack trace (!) in your dmesg. Maybe it's related to above intel modesetting.

Yes:

Bios is latest available!

I'll have a look at disabling Intel nomodeset and test later or tomorrow and report back. (This is a dual boot uefi machine booting via rEFInd)

Edit: booting the 3.13.7 kernel with intel,modeset=0 gives the same blank screen on graphical boot but the kernel loads fine - access vis ssh to downgrade the kernel to 3.13.6 and boot with the same parameter works fine though. So there remains a problem with the graphical boot for kernel .13.7

For the working 3.13.6 kernel the Xorg log is:

https://bugzilla.kernel.org/show_bug.cgi?id=61891

and I guess could have regressions as radeon patches have been included in kernel 3.13.7?

Re: [Solved]Control of automatic GPU switching in Linux 3.13

Reported to kernel bugzilla at https://bugzilla.kernel.org/show_bug.cgi?id=73291

Edit: After suggestion made in the above report I can workaround to get a successful boot to a graphical login by adding modprobe.blacklist=radeon to the kernel line.
