Summary: R580 Powermanagement with Kernelmodesetting: Product: DRI Version: unspecified Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: revealed@freakmail.de
Hello!
I hope you can help me on this: - Chipset: "ATI Radeon X1950" (ChipID = 0x7240) - OpenSuSE 11.4 2.6.37.6-0.7-desktop x86_64 GNU/Linux
I had the same problem with the 32 Bit version of SuSE 11.4.
I an able to start my system using kernelmodesetting. Most things related to my GFX seem to work fine so far.
As i read on the xorg wiki there is powermanagement available for many cards.
If i issue: cat /sys/kernel/debug/dri/0/radeon_pm_info
I recieve this output: default engine clock: 508000 kHz current engine clock: 506250 kHz default memory clock: 600000 kHz current memory clock: 594000 kHz PCIE lanes: 0
I was just wondering, why there is no Voltage information available. And as my card is a PCI Express Extension card and not an integrated one i thought i might find PCIE Lanes 16 normally?
In dmesg output i can also find: [ 2.614836] [drm] radeon: power management initialized
According to lsmod the lm63 module was loaded automatically. So theres a hwmon structure for my card.
And debugfs contains some dri related files and is also accessible by a normal system user.
But if i want to switch powerprofiles (profile based) or dynpm it won´t work. I installed the radeonpm plasmoid from kdelook.org as i would want to comfortably switch profiles.
I get temperatures and actual clock information from the for radeon created filestructure. But no voltage info?
While searching freedesktop for information, i found it could be usefull for you to have a look into "vbios.rom" as i dont know how to read it, i will attache mine here.
Many thanks for your Help!
Greetings,
