--- Comment #4 from Steve <netwiz at crc.id.au> --- I've been digging more into this.... I have 3 x displays - 2 x DVI, 1 x DP. Looking into debugfs, I can see that the clocks never change from sclk 900MHz, mclk: 105000. ie: # cat /sys/kernel/debug/dri/64/radeon_pm_info uvd vclk: 0 dclk: 0 power level 2 sclk: 90000 mclk: 105000 vddc: 1175 vddci: 1150 My kernel options are: # for i in /sys/class/drm/card0/device/power_*; do echo "$i: `cat $i`"; done /sys/class/drm/card0/device/power_dpm_force_performance_level: auto /sys/class/drm/card0/device/power_dpm_state: balanced /sys/class/drm/card0/device/power_method: dpm /sys/class/drm/card0/device/power_profile: default # for i in /sys/module/radeon/parameters/*; do echo "$i: `cat $i`"; done /sys/module/radeon/parameters/agpmode: 0 /sys/module/radeon/parameters/aspm: -1 /sys/module/radeon/parameters/audio: 0 /sys/module/radeon/parameters/auxch: -1 /sys/module/radeon/parameters/backlight: -1 /sys/module/radeon/parameters/bapm: -1 /sys/module/radeon/parameters/benchmark: 0 /sys/module/radeon/parameters/connector_table: 0 /sys/module/radeon/parameters/deep_color: 0 /sys/module/radeon/parameters/disp_priority: 0 /sys/module/radeon/parameters/dpm: -1 /sys/module/radeon/parameters/dynclks: -1 /sys/module/radeon/parameters/fastfb: 0 /sys/module/radeon/parameters/gartsize: 1024 /sys/module/radeon/parameters/hard_reset: 0 /sys/module/radeon/parameters/hw_i2c: 0 /sys/module/radeon/parameters/lockup_timeout: 10000 /sys/module/radeon/parameters/modeset: 1 /sys/module/radeon/parameters/msi: -1 /sys/module/radeon/parameters/mst: 0 /sys/module/radeon/parameters/no_wb: 0 /sys/module/radeon/parameters/pcie_gen2: -1 /sys/module/radeon/parameters/r4xx_atom: 0 /sys/module/radeon/parameters/runpm: -1 /sys/module/radeon/parameters/test: 0 /sys/module/radeon/parameters/tv: 0 /sys/module/radeon/parameters/use_pflipirq: 2 /sys/module/radeon/parameters/vm_block_size: 12 /sys/module/radeon/parameters/vm_size: 8 /sys/module/radeon/parameters/vramlimit: 0 # cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-4.4.3-300.fc23.x86_64 root=UUID=03ee98ed-d998-4518-b216-b77822a9319b ro quiet radeon.audio=0 radeon.tv=0 audit=0 selinux=0 # cat /proc/version Linux version 4.4.3-300.fc23.x86_64 (mockbuild at bkernel01.phx2.fedoraproject.org) (gcc version 5.3.1 20151207 (Red Hat 5.3.1-2) (GCC) ) #1 SMP Fri Feb 26 18:45:40 UTC 2016 -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
