I have enabled these options in the kernel and this error message is now gone: CONFIG_MTRR_SANITIZER=y CONFIG_MTRR_SANITIZER_ENABLE_DEFAULT=1 CONFIG_MTRR_SANITIZER_SPARE_REG_NR_DEFAULT=1 Unfortunately OpenGL performance is still unsatisfactory: [birdie@localhost ~]$ glxgears 4044 frames in 5.0 seconds = 808.746 FPS 4012 frames in 5.0 seconds = 802.318 FPS However this issue isn't a Linux kernel concern. Feel free to close this bug report if the aforementioned options are a must for the i915 drm functioning. note: glxgears isn't a benchmark. If you have performance problems with real apps you should file them at bugs.freedesktop.org. Thanks. |
Created attachment 25331 [details] Hardware and software info Intel Graphics HD video adapter doesn't perform well in OpenGL mode probably due to this error. I have Intel Core i5 650 CPU, 4GB of RAM and Intel H55 based motherboard. Some relevant hardware software/information is attached.
