RE: i915 trouble -- IRQ being disabled
I have the same problem too.
I ran glxgears for a long time then glxgears got hung. I looked into it and
found the 915 interrupt handler wasn't called, so
dev_priv->sarea_priv->last_dispatch is not updated anymore. However the ring
buffer works fine and the appropriate data had been written into the hardware
status page. The problem still happened after I unloaded/loaded drm module. But
this problem doesn't happen on another machine.
The following patch works fine for me (The IRQ is still disabled).
diff --git a/shared-core/i915_irq.c b/shared-core/i915_irq.c
index 5ff8788..b2905bb 100644
--- a/shared-core/i915_irq.c

return 0;
+ }
dev_priv->sarea_priv->perf_boxes |= I915_BOX_WAIT;
Thanks

Can you bisect it down to a single commit? If that's not possible with the kernel tree, you can try the drm git tree from git://git.freedesktop.org/git/mesa/drm . > Any ideas?
