This is the minimal patchset I have for working around the missed<br>
IRQs. I've been running it since Monday doing test runs for other<br>
work, and it appears to be stable.<br></blockquote><div><br>Works for me, no more missed IRQs nor hangs/delays with this patchset.<br><br>I have one questions though - would it be possible to control the interrupts behavior via a module parameter or debugfs entry to simplify debugging of this issue going forward?<br>
<br>For example, something like /sys/kernel/debug/dri/0/i915_irq_polling - writing '1' there would enable polling, and '0' would use the usual gen6_ring_get_irq. This would default to '1' on gen7, and '0' on older architectures.<br>
