https://bugzilla.kernel.org/show_bug.cgi?id=90451 Bug ID: 90451 Summary: Dedicated gpu on HP 355 G2 not working correctly (slower than integrated+corrupt display in es2gears) Product: Drivers Version: 2.5 Kernel Version: 3.16 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: l55@xxxxxxxxxxxxxxxxxxx Regression: No The HP 355 G2 has an integrated R5 Mullins and a dedicated Hainan GPU(R5 M240). Only the integrated one seems to work correctly. When running "DRI_PRIME=1 es2gears"(dedicated) i get corrupt image and lower fps than with "es2gears"(integrated), while i think the dedicated should be way better. These are the results on Ubuntu 14.10(kernel 3.16). I also tried the Gears on Gallium livedvd (2014.12.25) with kernel 3.19-rc1 and devel mesa/xorg/radeon drivers ( http://www.gearsongallium.com/?p=1668 ). With Gears on Gallium the switchable graphics don't seem to work at all, it seems to use the integrated gpu always, even with DRI_PRIME=1. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
