Bug ID: 64131
Summary: Radeon card stays in highest DPM power state on boot
and after resume
Product: Drivers
Version: 2.5
Kernel Version: v3.12-rc5-g34ec4de
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: lekensteyn@gmail.com
Regression: No
On startup (and after resume), I see the following:
switching from power state:
ui class: none
internal class: boot
caps:
uvd vclk: 0 dclk: 0
power level 0 sclk: 10000 mclk: 15000 vddc: 950 vddci: 950
power level 1 sclk: 10000 mclk: 15000 vddc: 950 vddci: 950
power level 2 sclk: 10000 mclk: 15000 vddc: 950 vddci: 950
status: c b
switching to power state:
ui class: performance
internal class: none
caps:
uvd vclk: 0 dclk: 0
power level 0 sclk: 10000 mclk: 15000 vddc: 950 vddci: 950
power level 1 sclk: 77500 mclk: 105000 vddc: 1150 vddci: 1150
power level 2 sclk: 84000 mclk: 105000 vddc: 1190 vddci: 1150
status: r
/sys/kernel/debug/dri/65/radeon_pm_info says:
uvd vclk: 0 dclk: 0
power level 2 sclk: 84000 mclk: 105000 vddc: 1190 vddci: 1150
The primary boot graphics device is an integrated Intel GPU, to which a monitor
is connected. The second HD6790 (BARTS) GPU is headless, but it still stays in
the highest power level (2). Only after X has started or an OpenCL program has
finished, power level 0 is entered.
Note: just attaching the a monitor does not change the power level, but the
switching to performance state kernel messages are printed. X *really* has to
be started with the AMD card being used for output, only then it will switch to
power level 0.
