Re: [Intel-gfx] [PATCH v2] drm/i915: Increase WM memory latency values on SNB
Thanks for this Ville. Should this apply to 3.14 and 3.15? I'll try it on 3.15 first and report back. ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx

A few days (and really hot temperature days for the laptop) not a single flicker or anything.

The DRAM config, is this something that I have to/should check?

Re: [Intel-gfx] DP1 Monitor Flashes
I too am having the same issue. I'm running on kernel 3.12.6 (just updated) The issue happens less frequently, but it still happens and it's quite annoying. Previously I would just get lines like this: [ 342.071567] [drm:ilk_display_irq_handler], Pipe B FIFO underrun [ 342.071584] [drm:cpt_serr_int_handler], PCH transcoder B FIFO underrun But after the recent kernel update it looks like there are some more debug messages being sent out like this: [ 624.430107] [drm:i915_driver_open], [ 624.439972] [drm:i915_gem_context_create_ioctl], HW context 1 created [ 624.450177] [drm:i915_gem_context_destroy_ioctl], HW context 1 destroyed I have a bug open for this, but I haven't heard a response on next steps unfortunately :( https://bugs.freedesktop.org/show_bug.cgi?id=70254 -- Robert Navarro ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
