[Bug 72921] DPM Power Cycle with AMD A8-6600K & MSI FM2-A55M-E33
https://bugs.freedesktop.org/show_bug.cgi?id=72921 --- Comment #11 from mmstickman at gmail.com --- If I recall correctly, I used AMD Radeon RAM when I built the system. I can't say whether or not the bug still occurs on the machine I posted this bug with because I built it as an office PC for someone else. Being a production machine, I didn't have any kind of boosters or overclocking features enabled. I think it's more than likely something to do with MSI's implementation of FM2/+ -- You are receiving this mail because: You are the assignee for the bug. -- next part -- An HTML attachment was scrubbed...

https://bugs.freedesktop.org/show_bug.cgi?id=72921 --- Comment #10 from Kertesz Laszlo --- Since this bug seems to be restricted to specific boards, without your help will be hard to solve it. You could try adjusting BIOS settings. Maybe you have some proprietary MSI specific "performance booster" settings or OC activated? Did you try resetting the BIOS to defaults? Do you have some special brand of memory? Also, looking at that dmesg output i see some lines beginning with "#" such as Jun 3 15:24:01 172.22.15.56 [ 51.381984] #011ui class: Jun 3 15:24:01 none etc. I dont have any of those in my dmesg and never had (A8-5500 and A8-6500 APUs on Gigabyte boards). -- You are receiving this mail because: You are the assignee for the bug. -- next part -- An HTML attachment was scrubbed...

https://bugs.freedesktop.org/show_bug.cgi?id=79806 Priority: medium Bug ID: 79806 Assignee: dri-devel at lists.freedesktop.org Summary: Performance degradation after resume Severity: normal Classification: Unclassified OS: All Reporter: enyecz at gmail.com Hardware: Other Status: NEW Version: unspecified Component: DRM/Radeon Product: DRI I have a Radeon HD 4350/4550 (RV770) card in my notebook. After resuming from suspend, there is a significant 3D performance drop (a bit less than 1/4 of original performance remains). The performance drop is exactly at the same level as it is after "echo low > /sys/class/drm/card0/device/power_dpm_force_performance_level", albeit power_dpm_force_performance_level still contains "auto". Bug is found in Ubuntu 14.04, but it was there at least since 13.10 (I have just found the workaround). The bug is there with kernel 3.13 (official), with 3.14 mainline and 3.15-RC8 which was build for Ubuntu 14.10. Workaround: when resume, execute "echo auto > /sys/class/drm/card0/device/power_dpm_force_performance_level". -- You are receiving this mail because: You are the assignee for the bug. -- next part -- An HTML attachment was scrubbed...

[Bug 77521] New: radeon: Horizontal lines of semi-random contents are sometimes displayed

They would only stay for a fraction of a second, before disappearing again. It's quite easy to trigger them by using the gnome expose function (the window overview).

lockdep splat while exiting PRIME
Hi,
While trying PRIME, I got a lockdep warning after exiting glxgears. Is
it harmful? The command was:
DRI_PRIME=1 glxgears
Offload provider is a GT425M (NVC0), output sink is an Intel i5-460M.
Kind regards,
Peter

looking for i915 direct programming sample application
Hi, did some more research. Is the following correct? -OpenCL is not yet supported for Intel GPU on Linux -i915 driver can be accessed by opening /sys/devices/pci/:00:02.0/device and ioctling it? Next I have to learn about output from GPU. In some docs I could read direct access to the graphics aperture from CPU is blocked by the hardware. I guess the output of GPU EUs must end up in the framebuffer. I need to learn how to create and read framebuffer devices.
