--- Comment #1 from Tom B <[email protected]> --- additional information: I can turn on/off the flicker using radeon dynamic power management: echo battery > /sys/class/drm/card0/device/power_dpm_state No flicker echo performance > /sys/class/drm/card0/device/power_dpm_state Flicker starts By changing the power state to performance the flicker happens. Using "battery" the flicker does not so it seems to be power related but not obvious. On "balanced" dpm, the flicker sometimes happens which is probably down to the power state. Changing the power state does not seem to affect the temperature at all. radeon-pci-0100 Adapter: PCI adapter temp1: +60.0°C (crit = +120.0°C, hyst = +90.0°C) Regardless of the power state the temperature is almost always exactly 60.0, sometimes it's 59.0 but there is no noticeable temperature difference between "battery" and "performance" and the clock speed does not seem to change Regardless of power state, the output of `cat /sys/kernel/debug/dri/0/radeon_pm_info` shows: uvd vclk: 0 dclk: 0 power level 0 sclk: 30000 mclk: 30000 vddc: 900 vddci: 850 pcie gen: 3 -- You are receiving this mail because: You are watching the assignee of the bug. ------------------------------------------------------------------------------ _______________________________________________ acpi-bugzilla mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
