Dear Linux folks,
although there are no user visible issues, there is still the following error message in the log. > [ 1.235596] i915: render error detected, EIR: 0x00000010 > [ 1.235596] i915: page table error > [ 1.235596] i915: PGTBL_ER: 0x00000012 > [ 1.235596] [drm:i915_report_and_clear_eir] *ERROR* EIR stuck: > 0x00000010, masking > [ 1.235596] i915: render error detected, EIR: 0x00000010 > [ 1.235596] i915: page table error > [ 1.235596] i915: PGTBL_ER: 0x00000012 > [ 1.310633] [drm:intel_modeset_init], 2 display pipes available. > > The intel-gpu-tools [6] include the program `intel-error-decode`, which > give the following. > > $ ./intel_error_decode /tmp/5927_7/error > Time: 1402269737 s 277725 us > Kernel: 3.14.4-gnuowen > PCI ID: 0x27a2 > Detected GEN3 chipset > EIR: 0x00000010 > IER: 0x00028053 > PGTBL_ER: 0x00000012 > Display A: Invalid GTT PTE > Host Invalid PTE data > […] Is there an option that the GTT is dumped on such an error or the addresses are shown in the logs to exactly see where in memory the problem is?
