[Bug 37841] New: Display distortion with powerprofile mid or low
https://bugs.freedesktop.org/show_bug.cgi?id=37841 Summary: Display distortion with powerprofile mid or low Product: DRI Version: XOrg CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: DRM/Radeon AssignedTo: dri-devel at lists.freedesktop.org ReportedBy: bugreport at spambog.com Overview: The display is distorted when power-profile low or mid is activated. Steps to reproduce: echo low > /sys/class/drm/card0/device/power_profile or echo mid > /sys/class/drm/card0/device/power_profile Actual Results: The display is distorted, but the system is still usable. The distortion consists of noisy flickering vertical stripes, with columns between them that look ok. When I choose powerprofile default or auto or high the distortion goes away and everything's as before. Output of cat /sys/kernel/debug/dri/{0,64}/radeon_pm_info: With powerprofile default: default engine clock: 50 kHz current engine clock: 499500 kHz default memory clock: 60 kHz current memory clock: 594000 kHz voltage: 1000 mV PCIE lanes: 16 default engine clock: 50 kHz current engine clock: 499500 kHz default memory clock: 60 kHz current memory clock: 594000 kHz voltage: 1000 mV PCIE lanes: 16 With powerprofile mid: default engine clock: 50 kHz current engine clock: 124870 kHz default memory clock: 60 kHz current memory clock: 405000 kHz voltage: 900 mV PCIE lanes: 16 default engine clock: 50 kHz current engine clock: 124870 kHz default memory clock: 60 kHz current memory clock: 405000 kHz voltage: 900 mV PCIE lanes: 16 With powerprofile low: default engine clock: 50 kHz current engine clock: 124870 kHz default memory clock: 60 kHz current memory clock: 405000 kHz voltage: 900 mV PCIE lanes: 16 default engine clock: 50 kHz current engine clock: 124870 kHz default memory clock: 60 kHz current memory clock: 405000 kHz voltage: 900 mV PCIE lanes: 16 With powerprofile high: default engine clock: 50 kHz current engine clock: 499500 kHz default memory clock: 60 kHz current memory clock: 594000 kHz voltage: 1000 mV PCIE lanes: 16 default engine clock: 50 kHz current engine clock: 499500 kHz default memory clock: 60 kHz current memory clock: 594000 kHz voltage: 1000 mV PCIE lanes: 16 Expected Results: No display distortion and perhaps other values in radeon_pm_info (values of mid and low profile should differ and perhaps there should have been some lanes deactivated by these profiles).

[PATCH v2] drm: Compare only lower 32 bits of framebuffer map offsets

After googling up an old "DRM map design" thread from 2005 (http://thread.gmane.org/gmane.comp.video.dri.devel/19545/focus=19689), and http://dri.freedesktop.org/wiki/DrmMapHandling I think I can answer this to some extent myself: For _DRM_SHM it is not an offset that is passed from/to userspace, but a handle, which I guess is kept within 32 bit. Although this is not fully clear to me after browsing through drm_addmap_core(), where the offset or handle is the result of vmalloc_user(). Tormod
