Or the interrupt change requests were invalid. In i915_irq.c, line 2050 we queue the RPS worker from the interrupt. That would be a good place for the first printk to verifiy we get interrupts. The next interesting function is ilk_compute_pm_iir() where we respond to the interrupt and see which way to reclock the GPU. Oh... gen6_pm_rps_work(): if (!dev_priv->rps.interrupts_enabled) return; that'll explain the lack of reclocking!</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
