[Bug 40762] Kernel crashes when activation powersaving feature of mobility radeon x1400
https://bugzilla.kernel.org/show_bug.cgi?id=40762 --- Comment #1 from Keivan Moradi --- I still have this problem in linux kernel 3.4.55 in ubuntu 12.04.2 - When I activate dynpm kernel craches. - In the profile mode also I get the same error as I did before. I have noticed that the kernel do not changes the GPU and Vram frequencies correctly in the profile mode. This is what I get when I set it to mid: # echo mid > /sys/class/drm/card0/device/power_profile # cat /sys/kernel/debug/dri/0/radeon_pm_info default engine clock: 432000 kHz current engine clock: 209250 kHz default memory clock: 396000 kHz current memory clock: 135000 kHz PCIE lanes: 1 This is what I get when I set it to low: # echo low > /sys/class/drm/card0/device/power_profile # cat /sys/kernel/debug/dri/0/radeon_pm_info default engine clock: 432000 kHz current engine clock: 324000 kHz default memory clock: 396000 kHz current memory clock: 135000 kHz PCIE lanes: 1 This is what I get when I set it to high: # echo high > /sys/class/drm/card0/device/power_profile # cat /sys/kernel/debug/dri/0/radeon_pm_info default engine clock: 432000 kHz current engine clock: 432000 kHz default memory clock: 396000 kHz current memory clock: 396000 kHz PCIE lanes: 0 If you look at the above values, it is obvious that the default clock of mid and low should be replaced with each other. -- You are receiving this mail because: You are watching the assignee of the bug.
